There is presently no way to efficiently correlate the natural laws of inertia with the art of a stepless automobile transmission. Unsuccessful efforts to invent a serviceable transmission have been on-going since the first automobile was produced and include numerous arrangements of the friction clutch and variations of the cone methods. The present invention is based on a unique and new principle, with no suggestion of precedent in prior transmission design. The low efficiency of a conventional power transmission contribute greatly to air pollution and fuel shortages. The inertial resistance to instant change of the velocity of a particle is so severe that no velocity change can occur in nature unless the change is stepless, regardless of the velocities involved. To name an instance, a drag racing vehicle makes it's own stepless transmission by wasting energy at the spinning wheels. All conventional power transmissions must have designed method of waste in order to be sufficiently stepless to work. If waste does not occur in a slipping power train, then it occurs in the engine cylinders via pressure variation that reduces the input torque and releases unburned carbon into the air. This condition is visible when a heavy truck is attempting along with much shifting and double clutching, to force

acceleration with power glut. In this instance the exhaust gases contain more carbon than the engine is burning. Stepless change of motion is enigmatic; it can be said if the change is stepless, it does not occur at all, and velocity is increased without the event of inertial resistance. Regardless of enigma, it is sufficiently observable that stepless power transmission nearly neutralizes inertial resistance, whereas conventional stepped transmission creates inertial resistance' that must be overcome with added input power. Barring gravity (hills and friction), it can be said that the manner in which a load is moved determines the load.

When conventional transmissions use a fluid action torque converter,-" reduction gearing multiplies the torque delivered by the converter turbine. Starting the movement of a vehicle in the relatively high ration of 3:1 underdrive, or low gear, is impossible without some form of slip-waste built into the system.

When a conventional transmission is in a 1 :1 , or high gear, mode there is no gearing to multiply the turbine torque; if the turbine is efficiently coupled and turning as fast as the input driven pump, the turbine provides very little driving torque. When acceleration is attempted in high gear, and more inertial resistance cuts in accordingly, acceleration becomes sluggish, and is accomplished by an extreme power glut which is necessary to sufficiently increase the converter pump RPMs ahead of the turbine RPMs to generate torque to change the vehicle velocity. Since typical driving conditions require frequent acceleration in high gear, it becomes a very wasteful factor.

Another impediment to solving the fuel and pollution problem is the resistance to change on the part of established producers.

A driving engine puts out mechanical energy in the form of torque and RPMs. The RPMs in the upper three-quarters of the engine range are subject to a degree or operator control by variation of the fuel input, or acceleration; the engine torque is

not subject to operator variation or control except as it naturally relates to the RPMs. the conventional systems of automobile power transmission provide the operator with a workable range of speed selection but are seriously lacking in the ability to provide an efficient output drive. The output load is comprised mostly of inertial and gravity resistance; the driving torque requirements for a given speed, or change of speed, varies almost continuously, i.e., the most efficient torque to RPM ratio varies almost constantly. The number of useful torque to RPM ratios within a common range of driving conditions is infinite. However, conventional power transmissions can only provide three or four distinct ratios. Thus, the ratio is seldom optional. A vehicle cannot move without sufficient torque, and so the engine must supply excess fuel and power which, most of the time, is dumped into the air as pollution and heat. This power glut has an adverse effect on engine combustion, thereby exhausting more unburned carbon.

Conventional power transmission does not have the low and stepless ratios to handle the starting loads of extensive and permanent over-drive gearing. A vehicle with a conventional transmission, driving on gentle terrain and at cruising speeds, is using only a fraction of. the input power generated by the engine because the output, with it's range limited to a 1:1 ratio and carrying little, if any, inertial and gravity loads, cannot digest the energy essentially generated by an engine that is forced, by the absence of overdrive gearing, to rotate as fast as the output. This excess combustion, along with the associated low quality burn due to low pressure, contributes substantially to excess fuel use and air pollution.

According to the present invention, acceleration is efficiently achieved by the smooth and stepless upward change of the ratio, while concurrently the input RPMs is appropriately increased. The conventional transmission accelerates by glutting the system with input torque, in one ratio, to get output RPMs up to a speed that

reduces the inertial resistance sufficiently for the next higher ratio to handle the load.

The public is not yet aware that a major source of air pollution and excess fuel use is due to the primitive state of the power transmission art and its secondary influence on engine combustion. However, stepless transmission such as that according to the present invention can reduce fuel use and pollution up to fifty percent and more. A recent unsuccessful effort to produce a serviceable stepless power transmission was based on the German patent of Manfred Koser. Koser's work involved the conventional cone system. More specifically, the method used cones back to back, "a split pulley", to vary the pitch diameter of the driving and driven pulleys to vary the input to output ratio.

A stepless hydraulic system according to the present invention, with a variable pump driving a hydraulic motor, is serviceable in low speed applications such as in some types of construction equipment. A high RPM hydraulic motor that can also provide starting torque requires movement of more fluid than is practical in automobile power transmissions.

The state of the art in railroad power transmissions involves a combustion power source that is delivered to the output via electric motors that provide a magnetic type starting torque related to the electric output of a diesel driven generator. Nothing in the transmission can provide a low enough ratio for one engine to start the train. Thus two or more engines are hauled in useless tow for the occasional event of producing sufficient torque to start the train in a relatively high ratio.

The transmission according to the present invention provides infinitely low rations and allows the same power source to start a train to pull it at high speeds.

Power transmission manufacturers refer to conventional planetary transmission and stick shift truck transmissions as efficient machines; they look to engines and other means to reduce fuel use and air pollution. However, the conventional power transmissioh is, in fact, the culprit responsible for more fuel waste and air pollution that all other industrial factors combined.

One aspect of the present invention is, therefore, to reduce excess fuel consumption and air pollution. In a conventional automobile transmission there is a low degree of correlation between engine input power and the transmission output load due to the opposition to the natural laws of inertia by the conventional system. This lack of correlation is conventually managed by the over-production of power that is, by design, dissipated to make the drive and driven work albeit inefficient. In other words, due to conventional make-shift automobile transmissions more fuel is wasted than is actually used, and this waste is the source of more air pollution than all other sources combined. The constant variables in an automobile drive train require a steplessly variable transmission with a substantially extended range to precisely correlate the input power with the output load and eliminate most of the fuel waste. The stepless transmission according to the present invention provides the necessary correlation. In addition, the steplessly variable power transmission according to the present invention provides increased performance including the quality of smooth phenomenal, acceleration which occurs during the stepless increase of ratio in simultaneous balance with the increasing input RPMs. The near neutralized effect of inertia is a pleasant experience for the driver, and because the wheel spinning phenomena of the conventional transmission is eliminated, the infinitely low and stepless ratios provide other new and exciting capabilities such as an increased ability to ascent sharp inclines in mud or snow.

Aspects of the present invention include reduction in the number of parts, the size, weight and cost of transmission and also to eliminate parts such as friction clutches that have a short longevity

The present invention comprises three basic means, however, each function can be accomplished with elements that vary in number, design, and medium. Variation in the implementation of these elements remains within the scope of the present invention but varies the strength of the transmission as well as a corresponding cost and size variation.

The three basic means in context with three performing elements are: (1) an input driven first gear with axially disposed teeth, reciprocating on diameters of; (2) an output driving gear; and (3) a transitive connection between the first gear teeth and a reaction base that steplessly restricts , and varies, the rotation of the first gear teeth, around the first gear axis, while the first gear axis rotates around the second gear axis, whereby, the path pattern of the first gear teeth is steplessly changed and this steplessly changes the input-output ratio.

These and other aspects and functions of the present invention may be better understood in relation to the following figures, the figures are presented for the purpose of illustration, and are not intended to limit the scope of the present invention in any manner.

As shown, the three basic elements that perform the three basic functions are: first gear; a second gear; and a transitive connection to a reaction. base (housing). In a preferred embodiment of the present invention, the input drive, from the engine, directly rotates the transmission pump, the carrier and the control unit 9, so the reaction base for this pneumatic drive is the engine cylinder head. Of course, the input power is variable according to the accelerator. However, an aspect of this invention is to precisely and efficiently allocate a torque to RPM ratio according to a variable output load, and this is accomplished by the transmission's ability to steplessly change the path pattern of the first gear teeth. The straight patterns provide higher torque and lower RPMs, while the path evolves through elliptic and more rounded patterns to provide higher RPMs with less torque. Since the input torque to RPMs composition is reallocated in the transmission, the transmission drive train provides a reaction basis for the force which changes the path of the first gear teeth. The variable disposition of reaction base, and the transitive connection to it, provide substance for a multitude of variation designs, within the scope of the invention. For example, the preferred embodiment provides a mechanically linked transitive connection from the first gear teeth to a reaction base (housing), via the third gear guide channels, the swivels, and seat 10. Also, pistons 29 holds the third gear axis 4 on orbit 22, and the reaction base for the fluid pressure on pistons 29 is a high pressure reservoir. Yet another accessorial

restriction on the rotation of the first gear teeth 8 comes from the restrictor turbine. Finally, the first gear axis 6 is driven directly by the engine.

To clarify, there are four means to the power train in the preferred embodiment, and variation in number or position of these means indicates a variation of the transmission, within the scope of the invention. A transitive connection to a reaction base is called the third basic means to the invention. A variation, within the scope of the invention, of the third basic means, is seen in variation A, as shown in figure 19, in which the entire third gear mechanic is omitted, and this includes the third gear 3, the swivels 12-20, the control unit 9 and seat 10 wit it's tire 46, wherein, a part of the restriction load from the first gear teeth is carried by the force from restrictor 21. A substantial part of the drive train goes through the direct engine driven rotation of the first axis 6.

Conventional transmissions, driven with a conventional torque converters, pass the entire drive from the input driven pump to the output driving turbine by fluid dynamics, excepting some late model vehicles lock the output to the engine in the highest ratio. Stock racing cars use a straight-through drive, and their lack of fuel efficiency is widely known.

The present variation A also shows how the first means a first gear 1 , may vary in number and position, and still remain within the scope of the invention. Figure 19, shows two first gears, and in accordance with this additional gearing is added to the second means, i.e. the second gear 2. All gearing fastened to the multi- meshed second gear cylinder is called the second gear 2. Variation B omits the restrictor 21 , and the third means is largely provided by the third gear guide channels and their supporting mechanics which include the swivels 12-20 and seat 10 swivels 12-20 and seat 10. However, smaller portions of the reaction load are carried by oil pressure behind piston 29, and the direct engine drive on the first

gear axis 6. Except for the omission of the restrictor 21, variation B, shown in figure 20, is similar to the preferred embodiment.

Variation C of the present invention is shown is figure 21, and is similar to variation A except that variation C has only one first gear 1 and has the double depth second gear channels as shown in figure 23 in order to provide more contact between the first gear teeth and the second gear channels. Also variation C has over-drive gearing. Extreme reduction occurs as the first gear teeth move on nearly straight lines, and multiplies the input torque accordingly, during the low starting ratios. The diametrical bias of teeth 8 is driven directly by the engine input, and the reaction base for this portion of the drive is the engine cylinder head. A fluid restriction, against the rotation of teeth 8, around their first gear axis, provides a variable drive that automatically adjusts the input torque to the output load. That is, when the output torque load increases, the path of teeth 8 becomes straighter, producing more torque and less RPMs. And, a constant speed is maintained by accelerating the input engine. However, as the output torque load decreases, the path of teeth 8 evolves towards more elliptic, rounded patterns to increase the output RPMs, and in order to maintain constant speed the input RPMs are reduced. It is an inherent characteristic of this variation C to evolve toward the highest output RPMs that are driveable by the input torque. Torque cannot occur without resistance, and torque is measured by the resistance that it overcomes. Thus, the present transmission provides the highest output RPMs that can be driven by the input torque, thereby using most of the energy released by combustion.

The amount of turbine torque that a fluid power transmission can generate is primarily related to the coexisting difference in the pump and the turbine RPMs, whereas the present restrictor 21 is capable of generating more torque on a moving turbine than a conventional converter type turbine because the present turbine 78

always rotates about one-third the RPMs as that of the output shaft. The conventional turbine rotates three or four times faster than the output shaft; this is made possible by the extreme low ratios provided by diametrical gearing.

In variation C of the present invention the overdrive gearing multiplies the load on gear 1 from gear 2 accordingly. The restrictor turbine provides a torque force that restricts the rotation of teeth 8 to reciprocate in the diametrical channels of the second gear 2, so that an extreme torque drive is placed on the output second gear which overrides and minimizes the load from the overdrive gearing.

The figures indicating that implementation of the invention requires at least three elements to execute three basically essential functions. The first element and it's function is an input driven first gear with it's teeth reciprocating in diametrically disposed channels of the second element, this second element and it's function is an output driving second gear, with diametrically disposed channels, receiving the first gear teeth. The third element is a transitive connection between the first gear teeth and a reaction base. This transitive connection changes the path pattern of the first gear teeth, to change the input to output ratio.

Although the basis of the invention is contained in these three elements and functions, the design variation of each element and variation of numerical and positional combinations of the elements provides substance for unlimited transmission designs within the scope of the present invention, i.e., the character of the first gear element is not lost in variation A, where two input driven first gears share the same elemental function, and the second gear element maintains the same function, regardless of how many meshes are fastened to the second gear cylinder. A distinction of the heavy duty preferred embodiment is that the third elemental function is split into four circuits to provide a transitive connection between the first gear teeth 8, and a static reaction base. The first circuit is a

transitive mechanical connection between teeth 8 and the housing 83, via the third gear channels, on through swivels 12-20 and seat 10 to housing 83. The second is a transitive connection between teeth 8 and a static reaction base, via the third gear channels on to pistons 29 that are further connected by fluid pressure to a pump reservoir. The third is a mechanical connection between teeth 8 and a static reaction base, via the first gear axis 6, on through carrier 32 and input shaft 31 to an engine cylinder head. The fourth circuit is a transitive connection between teeth 8 and a reaction base, via the first gear connection to gear 25, on through gear 26 to., a fluid connection to starter 80, and also the engine head via restrictor pump 79. A purpose of the aforesaid four circuit connection is to balance the strength of the transitive connections, it the driving contacts, between the input, and the output second gear 2. As shown in Figures 4, 5, 22 and 23, all of teeth 8 are driving at all times, and most of the teeth are placing a direct drive on the output second gear 2. The first gear also drives the second gear indirectly, via the balance gear 66, meshing with the standard teeth part 67 of the second gear 2.

The preferred embodiment can steplessly transmit driving power in three ways: (1) with the restrictor neutralized and the third gear in action; (2) with the restrictor in action and the third gear neutralized; and (3) with both the restrictor and the third gear in action.

Examining each numbered part of the present invention, the first gear 1 is shown in the preferred embodiment having axially disposed teeth, equipped with friction reducing sleeves. The unique gearing between the input driven first gear and the output driving second gear provides high load bearing strength as more than one- half of the first gear teeth are meshed at any time, and the third gear bad opposes the second gear load, thereby neutralizing any shear stress on the teeth. The Teeth 8 are

confined to reciprocate on the diameters of the second 2 and third 3 gears and these remain still, in the neutral mode, while their axis, 4 and 5 remain aligned. However, when third gear axis 4 moves away from axis 5, however slight, to form orbit 22, and the third gear is restricted by swivels 12-20 and restrictor 21 , output second gear 2, must rotate, at it's pitch circle, a distance that is approximately the distance that axis 4 moves on orbit 22, during a coexistent time, the reduction and torque at this point of transmission is related to the difference in the size of orbit 22 and the size of the pitch circle of the second gear 2.- The torque load on carrier 32, from driving the first gear axis 6, on orbit 7, is diametrically distributed by the multipurpose gears 24, 25 and 26.

The variation shown in Figure 19 indicates how a plurality of first gears may be implemented and the teeth 8 may be track rollers in lieu of studs with sleeves.

The second gear 2 is integrated with a cylinder shaped unit driven at one end by the first gear, and driving the output shaft at the other end via the overdrive pinions 27. The second and third gears always rotate slower than the first gear. For example, the input shaft may rotate several hundred times while the second gear rotates once, and generates torque accordingly, within the limits of the machine strength. The machine strength is increased substantially by use of the restrictor 21. With the strength provided, the phenomenal reduction and torque that the system can generate between the first and second gears, allows practical use of the overdrive pinions to steplessly increase the transmission range. The variation shown in Figure 12, omits the overdrive pinions, in lieu of a direct connection between the second gear and the output shaft, this arrangement is best for heavy, off the-road equipment. The third gear 3 is another ring gear that is sometimes called the channel guide. Section 4 shows this guide in the neutral mode and section 3 shows it's axis 4

moving on orbit 22 because the third gear axis rotates on orbit 22 during a forward mode, the third gear rotates counter clockwise, relative to it's own axis, but, the sprag action of swivels 12-20 does not permit counter clockwise rotation, as related to the housing. Since teeth 8 are confined to diameters of the second and third gears, and the third gear, reverse rotation, as related to the housing, is restricted by swivels 12-20 and restrictor 21 , any input motion curves the path of teeth 8 relative to the housing, and the output second gear is driven forward accordingly.

Variations A and C omit this third gear, along with coordinate parts including swivels 12-20 and control unit 9. The third gear axis 4 is essential to the geometrical discussion of the invention in all variations except A and C. When this axis is aligned with axis 5 the second and third gears remain still, in the neutral mode, while teeth 8 reciprocate on their diameters. When axis 4 moves away from axis 5, to form orbit 22, then the second gear rotates a distance that is approximately the distance that axis 4 moves on orbit 22. Thus, occurs the reductions and generation of torque. Axis 4 is moved radially by oil pressure on pistons 29.

All teeth 8 cross the fixed central axis of the transmission unit 5. It is also the axis of the input shaft, the output shaft, the second gear, the control unit and orbit 22. The first gear axis 6 is driven on fixed orbit 7 by the input driven carrier

32. Crank 33 is rotatably connected here, to assist in driving control unit 9.

The first gear teeth 8 are equipped with sleeve bearings and occur at the pitch circle of the first gear. In figure 12 a variation 8A shows teeth 8 to be track rollers. The control unit 9 provides means for the stepless change of ratio that includes the radial movement of axis 4. This unit is rotated at input speed by a special connection to the first gear via crank 33. This unit comprises pistons 29,

slide block 41, cylinder block 40, and slide block housing 45. Operator controlled oil flows through line 30 to move pistons 29, which moves block 41, which moves axis 4 to determine the transmission ratio. This unit is omitted in variations A and C Swivel seat 10 provides a fixed reaction seat for swivels 12-20, when clutch

11 is closed. When clutch 11 releases, the seat turns freely, thereby neutralizing the third gear action allowing a reverse drive if the restrictor is in the reverse mode.

Clutch 11, when closed, the vehicle will not move backwards. . When closed, the vehicle has a positive mechanical drive up to 1.5 to 1 overdrive and the seat will not prevent forward free wheel. The clutch should be open when the overdrive exceeds 1.5 to 1 overdrive. The overdrive range goes up to 3 to 1 overdrive. The clutch is released during the neutral and reverse modes by opening valve 74 to low pressure. A puφose of the swivels 12-20 is to provide a sprag action, as related to the housing, for the third gear that is guiding teeth 8. Section 5 shows the swivels in the neutral mode and any movement of axis 4 away from the working side 42, will seat swivel 12. The third gear, in section 6, rolls like a wheel, with the seated swivels being the grounded area. The working, or holding, swivels are near still, while the non-working swivels, on side 43 have lifted to ride the second gear, thereby eliminating the type friction that would occur in a ratchet and ball system. Although the rotation of the second and third gears is relatively slow, the main load-bearing dwell, on any swivel, is a split second. The place that the swivels bear rotates much faster than the actual swivel. At the instant the vehicle starts, the load on the swivels and the third gear, is less than the second gear load on teeth 8, and the load reduces to a minimal amount, in accord with the increase in the inertial momentum.

This preferred embodiment, as shown by section 9 is a heavy duty design for large freight trucks, whereas the aforementioned starting load on the third gear and the swivels is highly modified by force from the restrictor 21. The lighter duty non- positive transmission, as shown 'in variations A and C, indicates that the swivels 12- 20 and the third gear 3 may be eliminated.

Restriction 21 comprises a pump 79, a turbine 78, and a stator 80. It generates torque, that is transmitted to the first gear 1 via multipurpose gear.26, thereby modifying the mechanical output reaction load on the third gear 3, and swivels 12-20. This restrictor is neutralized, for the reverse and neutral modes, by opening valve 70 to low pressure, thereby releasing stator 80 via lock 68, while substantially reducing the restrictor oil volume.

The third gear 3 and swivels 12-20 provide for the positive mechanical drive, during the range from neutral up to 1.5 to 1 overdrive, while the restrictor modifies the load on them. During the range from 1.5 to 1 overdrive to 3 to 1 overdrive, the third gear 3 and the swivels 12-20 are neutralized, while the restrictor and the carrier driven axis 6 provide the input torque.

The restrictor generates more torque than a conventional converter because the gearing provides greater difference between the pump speed and the turbine speed. For example, in the common ratio of 1 :1 , the pump is rotating 3 times faster as the turbine. Extreme torque bads are put on the output second gear 2 by. the overdrive gearing, pinions 27, in order to increase the transmission range and reduce the motion of the second and third gears. The high torque load is well driven because of the phenomenal gear reduction and mechanical advantage provided by the diametrical movement of the input teeth 8 on the output second gear channel. That is, if the transmission leaves neutral into ratios that are near 300 to 1 underdrive, between the input and the second gear, the reduction and correlating torque at the

output shaft 28, is still 100 to 1 underdrive. Thereby, relegating the transmission limits to material strength. The multiple meshes at the output shaft and the low friction multiple meshes of teeth 8 with the second and third gears provide ample strength to carry said extreme loads. The reaction load, on the swivels, from teeth 8 via the third gear guide channels, would be nearly the same as the teeth 8 drive on the output second gear 2, except, the restrictor puts a constant clockwise force on teeth 8, via gear 26, thereby substantially modifying the load on the swivels and the third gear guide channels. The use of the restrictor 21 in combination with a third gear 3, is for heavy duty power transmission. Variation B used the third gear method, only, and variations A and C use only the restrictor 21. As the ratio increases, the load on the swivels lessens until the ratio reaches 1.5 to 1 overdrive, a point when there is no load on the swivels. The restrictor 21 and input driven axis 6, provides the drive, up to 3 to 1 overdrive, that is the highest driving ratio. Due to the high torque load on the second gear 2 caused by the overdrive pinions, the restrictor toque cannot override the positive mechanical drive of the swivels.

A basic difference in the present restrictor and a conventional torque converter is that the conventional torque converter transmits all of the input drive to the output by fluid dynamics. In restrictor 21, fluid dynamics transmits a part of the input drive while the first gear axis 6 is connected to and mechanically driven by input shaft 31 to provide another part of the input drive. When the restrictor is implemented in the preferred embodiment, fluid dynamics provides a smaller fraction of the power transmission, due to the mechanics of third gear and its supporting swivels. In variation B the restrictor is omitted entirely.

Thus, restrictor 21 provides a force that restricts counter clockwise rotation of the first gear teeth 8. While the mechanically driven first gear axis 6 provides the diametrical motion of teeth 8, that is a factor in the generation of extremely high

output torque. The light duty variations A and C, which omits the third gear 3 and it's supporting mechanics, rely on the restrictor and the input driven axis 6 to change the path pattern of teeth 8, to change the ratio. The restrictor action produces far more torque than a comparable action of a conventional torque converter. For example, at a 1 to 1 ratio, the restrictor pump is rotating three times faster as the turbine, but the conventional torque converter's lack of torque in the high ratios, has been so problematic that the later model vehicles lock the engine and the output together, in the high ratio. This is a trade-off, because any arrangement which does not include a stepless variation of ratio, in accord with the output load, is grossly inefficient.

One purpose of restrictor 21 is to take up the overdrive when the positive mechanical drive ceases at 1.5 to 1 overdrive, and continue the ratio increase up to 3 to 1 overdrive; another is to modify the compression stress on swivels 12-20, during very low ratios, while maintaining a positive, non-slip mechanical drive. The swivels provide a static reaction base for the third gear channel guides that guide teeth 8, and also restrict the counter clockwise rotation of the first gear 1. The restrictor places a clockwise force on teeth 8 via gear 26, thereby modifying the load on swivels 12-20, and the third gear. As the transmission ratio goes higher the load on the swivels decreases until zero load occurs at 1.5 to 1 overdrive. The power train from the input shaft to the output second gear 2, is split into several tributaries that include the orbiting drive of first gear axis 6, by the input driven carrier 32, the input driven rotation of control unit 9, that participates in driving axis 4 on orbit 22, the reaction force of pistons 29 holding axis 4 on orbit 22, the reaction drive from seat 10 and housing 83, to the guiding channels of the third gear 3, via swivels 12-20, and the force from the restrictor 21 that participates in the drive.

The structural principle of the restrictor is similar to that of a conventional torque converter, but the generated torque, is used to directly restrict the rotation of teeth 8 as opposed to the conventional converter's purpose, of driving the output. Consequently, the select name is restrictor, as opposed to converter. The restrictor is shown graphically in the figures, as an element without unnecessary detail.

Although a pump, turbine, and stator are the basic parts, the design variations, for this element are boundless.

The diameter 22 of the variable orbit axis 4 relates to the transmission ratio. The third gear axis 4 is radially moved by pressure on pistons 29. The diameter of this orbit, which may be infinitely small, divided into the pitch diameter of the second gear, is related to the ratio, where transmissions, large enough to minimize the machine tolerance may hold ratios such as 1000 to 1 underdrive, or smoothly increase the ratio up to overdrives that are limited only by material strength. This orbit 22 is essential to a positive mechanical transmission, as shown by section 9. The one way clutch bearing (truck bearing 23) with the inner race on the input carrier, and the outer race on the output driving second gear prevents the second gear from rotating faster than the carrier. The result is free forward wheeling during forward ratios up to 3 to 1 overdrive, to smooth the positive mechanical drive. This combination also allows a desirable type of automatic throttle breaking at the ratio of 3 to 1 overdrive.

The main reverse gear 24 is located on the first gear shaft, and meshes with gear 26 to provide the reverse mode, when gear 26 is locked via lock 69. Lock 11 releases seat 10 to neutralize the third gear, during the reverse mode, the driving mesh of the reverse mode is dramatically distributed between the main reverse gear 24 and the minor reverse gear 25, and the gears are connectively meshed by gear 26.

In addition, there is a minor reverse gear 25 which acts with gear 24 to transmit force from restrictor 21, via multipurpose gear 26, to restrict the counter clockwise rotation of teeth 8 to change their path pattern. During this time lock 69 is released. When multipurpose ring gear 26 is locked in place, by lock 69, it provides the static reaction to reverse the drive on the output second gear 2, via gears 24 and 25. this gear is fastened to the turbine side of restrictor 21 , and transmits a fluid force from the restrictor, that restricts counter clockwise rotation of the first gear teeth 8, while the first gear axis 6 is connected to, and mechanically driven, by the pump side of restrictor 21. When the transmission is in a forward or neutral mode, the lock 69 is released and gear 26 rotates slowly forward.

The steplessly changing, and the extremely low ratios, 300 to 1 underdrive, that are inherent to the present invention, make it practical to extend the transmission range, up 3 to 1 overdrive, by implementing overdrive pinions 27. A variety of output designs are indicated in the drawings, which include the output shaft 28 united with a shaft gear, and another design, with the output shaft fixed solidly to the second gear cylinder.

Control pistons 29 are activated by operator controlled oil pressure that flows through housing 83, via line 71 into the cylinder block 40. The action of these pistons moves the third gear axis 4 away from the center of the transmission. Low pressure on these pistons together with springs 38 move the third gear back into the neutral position. The position of these pistons is directly related to the transmission ratio at a coexistent time.

Input shaft 31 is part of the same piece that forms pump 79, in variations A and C. This piece fastens to carrier 32 with bolts 89 to form a solid unit that carries gears 1, 24, 25 and 88.

Carrier 32 fastens to drive block 94 that participates in driving crank 33 at input speed, regardless of the position of axis 4.

Crank 33 provides a driving input connection to control unit 9. the crank is connected to the input drive in a manner that rotates control unit 9 the same as that of carrier 32, regardless of the position of axis 4. the crank is driven by its connection to the first gear 1 at axis 6, by teeth 8 at torque track 95, by teeth 8 meshing with the third gear 3, channels, and by the corrugated fitting of grooves 93 to drive block 94. the crank has an internal driving connection to slide block 41 that has 30° play as shown in section 10. As shown in section 8, one-half turn of park lock 34 fastens the transmission in the park mode. The one-half turn meshes the lock with output shaft gear 102, and stops against an overdrive pinion 27.

Housing assembly bolts 35 fasten the two heading housing together.

The movement between swivel pin 36 and swivel 12-20 is minimal and oscillating. The pin bears a variable and fleeting load during approximately 30 % of an input revolution. The intangible location of the load rotates with the speed of the input. A function of restrictor 21 is to modify the ad on these pins.

Section 9 shows how the second gear is a multipurpose cylinder shaped unit with the present bearing supporting the output end. Although the second gear output 37 is a large bore type, the action is no more than the output shaft bearing 65, because the second gear rotates one third as fats as the output shaft 28.

Swivel springs 38 press the swivel into tire 46 an instant before the driving load compression occurs. As shown in section 6, with the transmission in the forward mode, the swivels on the working side 42 are seated, under compression, and nearly still, while the swivels on the non-working side 43 have lifted, and ride the second gear via swivel fulcrum 82. This action occurs during each input revolution.

The springs 38 provide a tightness and fidelity of contact that is necessary to prevent noise and maintain the reaction efficiently.

A basic function of the present invention, is the objective restriction of the rotation, of the first gear 1, by anti-friction means. The embodiment, shown in figure 9, uses a method which allows the restricting swivels 12-20 to extend through the second gear cylinder, via second gear cylinder slots 39, to the fixed reaction seat 10. Variations, as indicated by detail, eliminated the entire combination, containing the third gear 3, the swivels and swivel seat, the slots and the entire control unit, and executes the aforesaid restriction via the single action of restrictor 21. the slots are included in the preferred embodiment, because of the sprag action, as related to the housing, of the load bearing swivels. Means to accomplish the restriction are many, such as ratchets and one way clutches, and may be substituted in lieu of the means shown in the figures.

Cylinder block 40 is part of control unit 9, and is bolted to slide block housing 45 to provide rotatable support for radially movable slide block 41 ; block

40 is also aligned with and rotatably connected to output shaft 28. This block carries the oil flow through line 30, that moves slide block 41.

As shown in section 7, slide block 41 is radially movable by force from piston 29. Section 9 shows that the present slide block shaft carries, on one end, the third gear shaft 77. Section 10 shows that there is 30° of play between the driving crank 33 and the driven block 41 which allows pistons 29 to remain approximately 90° off a line from axis 6 to axis 4, regardless of the position of axis 4. This 90° disposition of pistons 29 is not a critical factor, but contributes to the efficiency of the pressure in line 30. As seen in section 10, torque is transmitted to block 41 from crank 33 when the transmission is in the neutral mode, this prevents the would-be adverse effects of quick-starting unit 9. When the transmission is in the

forward mode, unit 9 is rotated by the input driven crank 33, that binds to the block 41 shaft, because it orbits around a different axis than that of crank 33.

Working side 42 indicated the side of the transmission wherein swivels 12- 20 descend and seat on tire 46 to provide the reaction force necessary to the transmission method indicated by the preferred embodiment shown in Section 9.

Non-working side 43 is indicated on the side of the transmission, where swivels 12-20 depart from their seat on tire 46 and ride on the second gear cylinder. Although the second gear and the third gear turn together, at constant velocity, during a ratio, the swivels stand still and bear on the working side, while they catch up on the working side. This is due to the variable angular disposition of the swivels that also determines the lengths of cylinder slots 39.

Third gear gear grooves 44 are a design factor which provides lateral support for swivels 12-20 and also allows them to fold in for compactness.

Slide block housing 45 is one of the control unit parts that bolts to cylinder block 40, with bolts 85, to form a supporting and rotatable housing for slide block

41 .

Seating tire 46 is a rubber-like piece, fastened to seat 10, for purposes which include noise prevention. Also, the tire compresses slightly to distribute the reaction load among three or four swivels. Any swivel, in the working area 42, that is not under compression, is coexistently driven into bearing position by springs 38. The plasticity of the tire allows springs 38 to force the swivels to indent the tire, before the compression bad occurs, the swivels are comparable to a nine tooth gear, multiplied by an underdrive ratio, and the tire smooths and dampens this function of the transmission. For example, in a 10:1 underdrive ratio the swivels would act on the output second gear, like a gear with 90 teeth.

One revolution of the second gear 2 indicates three revolutions of the output shaft 28. Th output signal revolution 47, together with a clock, provides the data for a dashboard speedometer, and part of the data for computer aided vehicle operation. Input revolution signal 48, together with signal 47, provides data which indicates the transmission ration, in the preferred embodiment. Signals 47 and 48 indicate the transmission efficiency when applied in the non-positive drive variation, shown in section 19.

Input head 49 fastens to tube 30 and output head 92, to make housing 83. The input shaft is solidly fastened to carrier 32, and input shaft bearing 50 shares a bearing load with bearing 55.

The first gear minor bearing 51 shares a load with bearing 54. Parts 31 and 32 are solidly bolted together and provides alignment. Bearings 52 provide support to gear 25. Although multipurpose ring gear bearing 53 is one of the large bore bearings, the action taking place is minimal because both races of the bearing turn in the same direction at nearly the same RPMs.

Major bearing 54 of the first gear 1 shares a load with bearing 51.

Carrier bearing 55 shares a load with bearing 50; this is a large bore bearing, but the action is modified because both races rotate in the same direction, i.e. the bearing action is related to the difference in the input RPMs and the second gear RPMs; as the ratio increases, bearing action goes down, until there is no bearing action when the ratio reaches 3 to 1 overdrive.

The input side second gear bearing 56 shares a load with the output side second gear bearing 85. Although these are large bore bearings, the slow rotating second gear, turns one third the RPMs as that of the output shaft 28, so the second gear bearing action is about the same as output shaft bearing 28.

Input side swivel seat bearing 57, and output side swivel seat bearing 58 rotate one third the RPMs as shaft bearing 65 when the transmission is in the forward mode. During reverse mode, both races rotate with the second gear cylinder, so there is no bearing action at all. The carrier rotates control unit 9 via a three part combination that includes a torque drive on track 95 by teeth 8, a torque drive from carrier teeth 93 to crank teeth 75, and a crank action from the first gear 1 to crank 33, that is rotatably supported by crank bearings 59. This three part combination drives axis 4 on orbit 22, regardless of its radial position on orbit 22, and also maintains axial alignment between axis 4 at control unit 9 and axis 4 at carrier 32.

The load on tooth 8 from the second gear is in the opposite direction as that of the load from the third gear. Whereas, each tooth 8 is equipped with two friction reducing sleeves 60 that rotate in opposite directions. The aforesaid relates to the preferred embodiment, as shown in section 9 and section 3, but, as shown by the variation in section 19, anti-friction designs may include roller bearings and track rollers.

The third gear bearing is located between the third gear shaft and the crank shaft to provide rotatable support for axis 4.

The action of the large bore control unit bearing 62 is modified, because both races rotate in the same direction, and the bearing action is related to the difference in the input RPMs and the second gear RPMs. As the ratio increases, the bearing action decreases until there is no bearing action at all, when the ratio is 3 to 1 , overdrive occurs.

The alignment bearing 63 maintains a rotating alignment between control unit 9 and output shaft gear 98, to support the action of seals 104.

The overdrive pinion bearings 64, together with lugs 97, supports pinions 27.

The balance gear 66 is fastened to minor reverse gear 25. and meshes with the output second gear, standard teeth part 67. The mesh between gears 66 and 67, provides a diametrical distribution of the input drive on the output.

The second gear standard teeth part 67 diametrically -balances the input drive on the output second gear cylinder.

When valve 70 is opened to high pressure, stator lock 68 locks stator 80 in place to generate torque for the forward mode. When valve 70 is on low pressure, the lock releases for the neutral and reverse modes.

When high pressure is on the reverse lock piston 69, via valve 73, multipurpose ring gear 26 cannot rotate, thereby becoming a static reaction for gears 24, 25, 66, and 1.

The five binary valves 70, 71 , 72, 73 and 74 and their oij lines appear only in the preferred embodiment; variation B has only four valves, and variations A and C have only three valves. Each valve may open to high or low pressure, according to signals from computer 1.12. When valve 70 opens to high pressure, for the forward mode, high pressure oil flows into restrictor 21 , and stator lock 68 pressure locks stator 80 in place. Meanwhile, valve 73 is on low pressure and multipurpose gear 26 is free to rotate; static reaction seat 10, is locked in place by high pressure at valve 74.

Valves 70 and 72 are wired to the same signal, but they are always on opposite pressures. When valve 72 is opened to low pressure, providing a cooling oil flow from valve 70, across the transmission and out valve 72. The cooling oil leaves the restrictor via the tight space between the pump and turbine in a much smaller volume than the potential high pressure input at line 70; the restrictor passes

cooling oil, but still remains full for the forward mode. High and low pressure at valve 71 are factors in the position of control pistons 29 which determines the transmission ratio.

When valve 70 opens to bw pressure for the neutral mode, valve 72 opens to high pressure, continuing the cooling flow, but changes the direction, to a high pressure input from valve 72, across the transmission and out to low pressure, through valve 70. Although cooling oil seeps into the restrictor, between the pump and the turbine, the low pressure output suction at valve 70 keeps the restrictor oil volume down for the neutral and the reverse modes. Meanwhile, the low pressure at valve 70 has released the stator lock 68, and stator 80 rotates freely in either direction to further neutralize restrictor 21. During the neutral mode valves 71 , 73 and 74 are opened to low pressure; low pressure at valve 71 , allows the third gear axis 4 to align in the center with axis 5 which is its neutral position, .and valve 73 frees gear 26 via lock 69, and valve 74 neutralizes the third gear mechanics by releasing seat 10 via lock 11. When the transmission changes from neutral to the reverse mode, valve 73 changes to high pressure to lock gear 26 via lock piston 69.

The crank teeth 75 mesh with carrier teeth 93, and all are milled on arcs around axis 6. This allows the input carrier 32 to deliver a smooth rotary drive to control unit 9, via the crank teeth 75, regardless of the radial position of axis 4. Drive block stud 76 facilitates the assembly of block 94 that carries the driving teeth 93.

The third gear shaft 77 carries grooves 44 and third ger channel guides 3. This shaft carries the reaction force from the swivels to the third gear channels that guide teeth 8. The output driving part os the restrictor is turbine vane 78. This turbine is fastened to the multi-purpose gear 26 that rotates slightly faster than the second

gear; the second gear can never rotate more than one third the RPMS than that of the output shaft 28. As an example, in the common ratio of 1 to 1 , the turbine is rotating one third as fast as the input driven restrictor pump, thereby generating much more torque than a conventional torque converter in a conventional transmission in the same ratio. The turbine and restrictor are designed relatively small, because their purpose is to assist in bearing the reaction load on swivels 12- 20, but, not to override the positive mechanical drive until the ratio goes higher than 1.5 to 1 overdrive. When the restrictor takes over the drive up to 3 to 1 overdrive. In other words, the transmission is in 3 to 1 overdrive before the restrictor ceases to generate torque.

In the present invention, both the restrictor pump 29 and the restrictor 21 may be designed smaller than a conventional torque converter in a comparable vehicle because the first gear axis 6 is driven on orbit 7 by carrier 32 that is fastened to the input shaft 28. This mechanical drive axis 6 is the force which drives teeth 8 on diameters of second gear 2, and this is a large part of the total input drive. Therefore, a lesser part of the input drive is sustained by the fluid dynamics, in the preferred embodiment which has a positive mechanical drive from the third gear mechanics, the function of the fluid dynamics is further reduced and is not an essential part of the input drive. However, restrictor 21 is included to cut-in for heavy duty power transmission.

The pump action and the inertial effect on the working fluid increases the fluid velocity by directing the fluid in a high frequency spiral around the pump axis. When the stator 80 is rotating freely in the neutral and reverse modes, most of the fluid energy is dissipated centrifugally into the restrictor walls. However, when stator 80 is fastened to a static reaction seat via lock 68, the angle of the stator vanes changes the direction of the fluid and the frequency of the spiral path directing the

fluid toward the turbine vanes, and the turbine vanes places a force on multipurpose gear 26 that restricts the counter clockwise rotation of teeth 8.

The third gear and the second rotate the same RPMs, but the third gear axis 4 also rotates on orbit 22. This causes the swivels to seat and lift, as opposes to the drag action of a rachet system. Although each swivel acts only in it's respective slot 39, the seat and lift action is improved by swivel fulcrum 82. The fulcrum straddle the slots and provide more precise bearing for the rocker action. This constant contact of the swivels, and the springs and pliant tire 46 prevents noise and smooths the action. The housing 83 comprises two heads a middle tube and a fill block.

As shown is figure 1 , the transmission according to the present invention has a housing 83 made with housing tube 30 enclosed with an input head 49 and an output head 92. These heads are fastened to tube 30 with bolts 35. The input heads supports an input shaft 31 via bearings 50, and also supports the turbine side of a gear 26 via bearing 94. Another side of gear 26 is rotatably mounted on the inside of a second gear 2 via bearing 53. An input shaft 31 is fastened to a carrier 32 via dowel bolts 87, to form a solid unit, that rotatably supports gears 1 , 24, 25, and 66. The solid unit also forms a pump part of a restrictor 21. Restrictor 21 comprises a pump 79 a turbine 78 and a stator 80. The stator 80 is rotatably mounted on the input head 49 via stator bearing 81 and held in place by stator lock 68. The input head 49 has an oil passage line and a binary valve 70 that connects to stator lock 68 and restrictor 21. A second gear 2 is a cylinder-shaped unit that is rotatably supported by housing 83, via bearings 56 and 85 and a furring block 84. A first gear 1 is rotatably mounted in carrier 32 and has axially disposed teeth 8 that are each covered with two sleeve bearings 60. The teeth are transitively connected to diametrically disposed second gear channels. A ger 24 is milled into the first gear

shaft and meshes with gear 26. A balance gear 66 is fastened to gear 25 and meshes with the standard tooth part 67 of the second gear 2. The first gear 1 is rotatably connected to a crank 33 and teeth 8 are transitively connected to crank 33. Carrier block 89 fastens to carrier 32 via studs 97, and carrier block teeth 88 are moveably meshed with crank teeth 75. Crank 33 is connected to control unit 9 via slide block 41 that is moveably fitted on a cylinder block 40, and a slide block housing 45. An output shaft 28 is rotatable supported by control unit 9 via bearing 63 and further supported by the output head 92 via bearing 65. Control unit 9 is rotatably mounted on the inside of second gear 2 via bearing 62. A third gear 3 and a third gear shaft 77 are rotatably mounted on crank 33 via bearing 61. Swivels 12- 20 are loosely connected to the third gear shaft ar grooves 44 by swivel pins 36. Swivels 12-20 are laterally and transitively supported by slots 39 in the second gear 2. A seat 10 is rotatably mounted on the outside of the second gear cylinder via bearings 57 and 58. A tire is fitted on the inner side of seat 10. The second gear 2 meshes with overdrive pinions 27 rotatably supported by studs 97 via bearing 64.

A piston 11 and lock balls 99 are fitted into the housing tube 30 and an oil passage connects piston 11 to high and low pressure oil via binary valve 74. Another piston 69 and lock balls 100 are fitted into housing tube 30 and an oil passage connects piston 69 to high and low oil pressure via binary valve 73. Pistons 29 are fitted into cylinder block 40 and an oil passage through head 92 connects these pistons to high and low pressure oil via binary valve 71. A cool oil passage occurs in head 92 and connects the inner transmission to high and low oil pressure via binary valve 72. Swivel springs 38 transitively connect the swivels to the third gear 3. The dashboard control mechanics, that can be implemented with this preferred embodiment, can vary, is design, from totally manual, to totally under computer control. In order to fully discuss the transmission operation a dashboard control

schedule is defined bebw, and it is seen that the control method is partly manual and partly automated via computer.

As seen in figure 22, an operator's dial 100 has a forward section 102, a neutral section 103, and a reverse section 104. The forward section has an incremental Miles Per Hour scale 108. A movable mounted mode and speed selector 101 is mounted on the operator's dial 100, and it is electronically connected to a computer 112. An output RPM indicator 105 is mounted on the operator's dial 100 and is electronically connected to an output RPM data source 113, and also to the computer 112. An input RPM indicator 106 is mounted on the operator's dial 100 and is electronically connected to an input RPM data source 114 and computer 112.

A pump 115 is hydraulically connected to a high pressure reservoir 116 and a low pressure reservoir 117, and to an electrical source 118. The high pressure reservoir 110 and the low pressure reservoir 111 are both hydraulically connected to each of a group of binary valves that includes valves 70, 71, 72 and 73. These valves are also electronically connected to the appropriately programmed computer

112, and electrical source 118. Valve 70 is hydraulically connected to restrictor 21 and the stator lock 68; valve 71 is hydraulically connected to a piston 29; valve 72 is hydraulically connected to a cool oil line; valve 74 is hydraulically connected to piston 69; and valve 73 is hydraulically connected to piston 11. All of these valves are electronically connected to the computer 112 and electrical source 118. Valves 70 and 72 are wired to be at opposite pressures at all times.

Figures 12 and 13 show the input driven first gear 1 meshed with the output driving ring gear 2 and the third gear 3 channel guide shown by dotted lines, This first gear teeth 8 are confined, immutably, to reciprocate on the diameters of the second and third gears. First gear axis 6 is driving on orbit 7 while the second and third gears remain still with their axis aligned to provide the neutral mode.

Figure 14 indicates the movement of axis 6 alone orbit 7 by plotting its position at 22 (1 2)° intervals, and also, the correlating position of a tooth 8 when the second gear is still, these showing the geometric necessity that tooth 8 move on a straight line relative to the second and third gears. In figure 15, the third gear axis 4 is moved away from gear axis 5 and teeth 8 are still meshed with and confined to the diameters of both the second and third gears. It is also seen that any movement of the input driven first gear axis will force the output second gear, or the third gear, or both, to rotate; rotation of axis 6 on orbit 7 drives axis 4 on orbit 22 around axis 5. Figure 16 indicates that axis 6 has driven 22(1/2)° and rotated axis 4 on orbit 22, 22(1/2)°. Diameter X is always aligned with axis 4 and 5. the terminal of diameter X is prevented from moving with axis 4 by swivels 12-20, resulting in the perimeter of gears 2 and 3 rotating a distance Z that is similar to the motion of axis 4 during a coexistent time. In figure 17, a continuation of the plotting shown in Figure 16 serves to plot a tooth 8 pattern for a particular ratio that is also in correlation with the size of orbit 22.

In the operation of the preferred embodiment of the transmission according to the present invention in the neutral mode, engine output shaft is fastened directly to input shaft 31. A computer 112 electronically prevents the engine from starting except when the operator's mode stick 101 is in the neutral sector 103 of an operator's dial and mode stick 100.

The preferred embodiment is a heavy duty power transmission with a multi- path power train, and with parts that can be cut in or out, to provide three different power train arrangements. For example, the power transmission can occur at restrictor 21 , while the third gear 3 is neutralized; it can occur at the third gear 3

while restrictor 21 is neutralized; or the present transmission can carry extremely heavy bads when both restrictor 21 and third gear 3 are working together. The following description defined the arrangement that includes both restrictor 21 and third gear 3 working together to provide a heavy duty power transmission.

With the engine and valve pump 115 running, and the mode stick 101 in the neutral sector 103 of the dial 100, the computer 112 signals the activation of the neutral mode. Accordingly, valve 70 opens to low pressure thereby releasing stator 80 to rotate neutrally and freely, and also reducing the fluid volume in restrictor 21 via low pressure line 70 to neutralize the fluid drive.

Meanwhile, valve 72 is opened to high pressure by the same neutral signal from computer 112, and cool oil flows through head 92 via line 72 and on across the transmission unit to the tight space between turbine 78 and pump 79, where it flows through and out of the transmission via low pressure line 70. The tight space between the restrictor pump and turbine, does not allow oil to flow into the restrictor as fast as it can flow out at the low pressure line 70, hence the desired low oil volume in restrictor 21 for the neutral mode, is maintained while a degree of cooling circulation continues.

Meantime, the same neutral signal from the computer 112 activates valve 71 to open to bw pressure which allows pistons 29 to remain seated in the neutral position; i.e., axial alignment of axis 5 and the third gear axis 4. An input driving carrier 32 is rotating the first gear axis 6 and a balance gear axis on fixed orbit 7 while the first gear teeth 8 reciprocate in the diametrically disposed guide channels of the second and third gears, and the second gear 2 and the third gear 3 remain still, in the neutral mode.

At the same time, during the neutral mode, and according to computer 112, binary valve 73 is open to low pressure, and multipurpose gear 26 and turbine 78 rotate slowly in a clockwise direction, without driving. Concurrently, pump 79 is rotating at an input speed via carrier 32 without transmitting any drive because stator 80 can rotate freely, in both directions, and the restrictor fluid volume is below the driving level because of the low pressure line 70-

Meanwhile, binary valve 74 is open to low pressure, according to the neutral signal from computer 112. Although seat 10 is free to rotate at this low pressure, it remains still, during this neutral mode. At the same time, an input driven carrier 32 and first gear 1 are both rotating control unit 9 via a unique and transitive connection to a crank 33. This transitive connection provides a three way drive that rotates control unit 9 at constant input speed regardless of the radial position of third gear axis 4. This three way drive is comprised of a driving, but movable, connection between carrier teeth 88 and crank teeth 75, and a constant but transitive drive on crank 33 from teeth 8 in crank track 95, and a cranking drive, on crank 33 from it's rotating connection to the first gear axis 6, that is input driven around orbit 7.

The first gear axis 6 and balance gear axis 120 are input driven on orbit 7 by carrier 32. the first gear teeth and the balance gear teeth rotate counter clockwise, the amount necessary for the teeth to reciprocate on diameters of the second and third gears while they remain still, in the neutral mode. The first gear 1 , and the balance gear 66 are fastened to gears 24 and 25 that have smaller pitch diameters. Gears 24 and 25, mesh with the multipurpose gear 26 thereby causing gear 26 and turbine 78 to rotate clockwise, slowly, with no driving effect, during the neutral mode.

In review, the input driven carrier 32 rotates pump 79, axis 6, axis 120, crank 33, and control unit 9, in a clockwise direction at input speed, while all other parts remain still.

While the transmission is in the neutral mode, the computer 112 will allow the mode stick 101 to be moved to the reverse sector 104 or the forward sector 102.

In the reverse mode pitch diameters of gear 24 and 25, being slightly less than the pitch diameter of gears 1 and 66, act so that when the second gear 2 is held still by the vehicle load, during the neutral mode, the difference in pitch diameters and teeth forces multi-purpose gear 26 to rotate forward, in a clockwise direction, approximately one-fifteenth the RPMs as that of input driven carrier 32. When operator's stick 101 is moved into the reverse sector 104 of dial 100, the computer 112 opens valve 73 to high pressure on piston 69 thereby stopping and holding gear 26 by ball clutching it to the house 30. According to this gearing, the output driving second gear 2 must rotate counter clockwise, in reverse, approximately one- fifteenth the RPMs as that of the input driven carrier i.e., while gear 26 is held still, the second gear 2 is rotating in reverse , at the approximate ratio of 15 to 1 underdrive. The design of the preferred embodiment includes the overdrive pinions 27, so, the input to output ration, in reverse is approximately 5 to 1 underdrive. The valve position, in the reverse mode, is the same as that in the neutral mode, except valve 73 is open to high pressure to hold gear 26. this valve 73 is open to taw pressure during the neutral and forward modes.

Second gear 2 and third gear 3 are transitively pinned together by the first gear teeth 8 so that gears 2 and 3 rotate together, at the same RPMs, around their respective axis, however the low pressure at valve 74 allows third gear 3, swivels 12-20, and seat 10 to rotate, slowly, in a reverse direction without any driving action, during the reverse mode. Carrier 32, crank 33, and control unit 9 rotate at

input RPMs during all modes, this prevents quick start shock when the transmission begins to drive forward.

When the operator's speed and mode stick, is placed on the line between the neutral sector 103 and the reverse sector 104, the computer 112 signals valve 74 to alternate between high and low pressure, at a designed frequency, to provide a downhill brake action in the transmission..

The forward mode of the present preferred embodiment provides a variety of driving dispositions. For example, in a vehicle, standing with the engine running, and the transmission in the neutral mode, if the driver desires to accelerate at the maximum rate and reach a speed of one hundred miles per hour and to maintain a steady speed while the output, bad varies, speed and mode stick 101 is pushed forward to the one hundred miles per hour mark on scale 108 on the forward sector of the operator's dial 100. When stick 101 enters forward sector 101 , all binary valves act according to the computer 112 signals. Thus, valve 70 opens to high pressure, to activate restrictor 21 by locking stator 80 and increasing the restrictor fluid volume to the working stage. Restrictor 21 is a driving accessory, as opposed to a driving necessity. Valve 73 remains open to low pressure so gear 26 and turbine 78 can rotate in a clockwise direction. Valve 72 opens to bw pressure allowing cooling oil to flow from high pressure at restrictor 21, through the tight space, between pump 79 and turbine 78, across the transmission and out valve 72 to low pressure reservoir 117. Oil cannot flow out of restrictor 21 as fast as it can flow in at high pressure line 70, thus an operating fluid volume is maintained in the restrictor while cooling circulation. Valve 74 opens to high pressure to lock seat 10 thereby activating third gear 3 mechanics by providing a static reaction base for the third ger sprag action via swivels 12-20. Valve 71 opens to high pressure on pistons 29.

The transmissfon ratio changes according to the change in the distance between second gear axis 5 and third gear axis 4, which distance is directly related to the position of piston 29, and while valve 71 is opened to high pressure, there is a constant force via pistons 29, toward increasing the distance between axis 5 and axis 4 however, pistons 29 cannot push axis 4 into a ratio, other than the coexisting ratio between the engine input and the vehicle speed. Thus, the transmission ratio changes in simultaneous accord with the change in the ratio between the engine input and the vehicle speed. There is a mechanical connection between the engine and the vehicle wheels, except during forward freewheeling. This mechanical connection exists during all ratios, up to 1.5 to 1 overdrive. In ratios that are higher than 1.5 to 1 overdrive, and on up to 3 to 1 overdrive, the third gear mechanics ceases to drive, and the output is carried by carrier 32 driving the first gear axis 6 around orbit 7, together with the turbine 78 force that restricts the counter clockwise rotation of teeth 8 via gears 1, 24, 25 and 26. The balance gear 66 is designed to provide a diametrically opposed input drive on output second gear 2.

When speedometer 105 aligns with the speed and mode stick 101 the computer 112 changes valve 71 to low pressure thereby preventing the ratio from going higher. If the output bad increases the input RPMs is increased to maintain constant speed. To reduce speed the input RPMs are reduced while stick 101 is pulled back to the desired speed indication.

If an extremely low speed is indicated by the position of speed stick 101 , such as one mile per hour, the transmission can provide this, but conventional combustion engines cannot limit the input enough to be fully efficient unless there is a degree of output torque load, such as mud, hill, etc. In conventional power transmission, wheel spinning occurs when the vehicle's inertial resistance to a sudden change in velocity is greater than the

resistance of the tire traction. The present stepless transmission provides extreme acceleration without tire spinning by neutralizing the vehicle's inertial resistance in stepless changes of the transmission ratio and stepless velocity changes of the vehicle. With favorable terrain and wind conditions, the transmission of the present invention can drive an ordinary vehicle up to three hundred (300) miles per hour. To drive in mud or snow, or up steep inclines, mode stick 101 is placed at a very low speed mark on scale 108, and the ratio remains extremely low, .If the input RPMs are increased without moving stick 101, the ratio goes lower. Change in the input RPMs can change the ratio, unless stick 101 is moved. The mode stick 101 can be moved anywhere except reverse on dial 100, at any time and any speed, while the engine is running. The mode stick can be moved from neutral into reverse at zero output RPMs. When pressure on pistons 29 moves the third gear axis 4 radially away from axis 5, axis 4 in input driven, clockwise, around axis 5 on orbit 22 by the input driven control unit 9, the third gear 3 is prevented from rotating counter clockwise relative to the housing 83. The counter clockwise rotation is prevented by swivel 12-20, reaction from the statically locked seat 10. This geometrical connection forces the third gear 3 to rotate clockwise at it's pitch circle a distance approximately equal to the distance around orbit 22. That is, if the diameter of orbit 22 is one-fourth that of the second gear diameter and axis 4 is input driven, 360° on orbit 22, then gears 2 and 3 must rotate clockwise approximately 90° in relationship to housing 83; the input rotates one revolution while the output driving second gear 2 rotates about 90°.

The input driving first gear teeth are transitively confined to the diametrically disposed third gear guide channels, and also transitively confined to the diametrically disposed guide channels of the output driving second gear 2. These gears 2 and 3 are transitively pinned together by the first teeth 8 and always rotate

together at the same RPM around their respective axis 5 and 4. The output driving second gear 2 is rotating 90° while the input driven third gear axis 4 orbits 360° thereby providing 4 to 1 underdrive, reduction, between the input and second gear 2. The 3 to 1 overdrive pinions 27 increase the ratio between input shaft 31 and output shaft 28 to a 4 to 3 underdrive. A stepless change in the size of orbit 22 steplessly changes the input-output ratio.

In figure 5, it can be seen that the reaction load on the third gear from teeth 8, would be similar to the force on the second gear from teeth 8. Except, a fluid bases clockwise force on teeth 8 from the restrictor turbine 78 via gears 1 , 24, 25, 26 and 66 substantially modifies the load on the third gear, the swivels and seat 10 with its tire 46, while placing an additional force toward driving output second gear 2.

A positive mechanical drive from the engine to the vehicle wheels occur in all ratios up to 1.5 to 1 overdrive. Any engine roughness is dampened by its forward free wheel character together with the fluid accessory force from turbine 78.

Power transmission between input driven first gear 1 and output driving second gear 2 occur at the transitive or rolling contact between teeth 8 and the second gear channels. The motion of teeth 8 is confined to straight line diameters of second gear 2. However, a curving path pattern of teeth 8 as related to a fixed housing is related to the input-output ratio. For example, when teeth 8 are reciprocating on straight lines relative to the housing the mode is neutral, however, during the highest ration the teeth circle around axis 5. A very slight arcuate curve of teeth 8 can rotate the output second gear 1° while the input shaft 31 rotates 360°. Furthermore, if output resistance is sufficient, torque can be generated in inverse proportion to the RPM ratios. The present preferred embodiment implements two

units to steplessly change the path pattern of teeth 8. These units are a restrictor 21 and a third gear 3.

Figures 12 through 17 show how the path pattern of teeth 8 are steplessly changed by the guide channels of the third gear 3 to steplessly change the input- output ratio.

In figure 5, more specifically, to tooth 8 on the bottom side of first gear 1 marked by the number 8, it is already known that tooth 8 is confined to movement on the straight line diameter of second gear 2, relative to the second gear 2. It can be seen that if third gear is prevented from rotating counter clockwise, as related to a fixed reference, by swivels 12-20 seating on tire 46 of seat 10 fixed to the housing 83, then output driving second gear 2 must rotate clockwise, forward.

During the neutral and reverse modes, all moving parts in diametrically balanced rotation, but in the forward mode third gear axis 4 orbits around central axis 5 at input revolutions in a clockwise direction while third gear 3 rotates on axis 4 in a counter clockwise direction. However, the pitch circle of the third gear is pinned to second gear 2 by teeth 8, and both the second and third gear rotate clockwise, together, relative to the housing. This rotation of the third gear is one- third the RPMs of output shaft 28. Referring specifically to figure 7, this action is similar to the dynamics of a rolling wheel, because the non-working side 43 is moving twice as fast as the orbiting axis 4, while the working side 42 is relatively still, and the centrifugal pull caused by direction change at the non-working side counter balanced by the velocity changes that occur on working side 42.

The only parts of the preferred embodiment that lift and seat are swivels 12 through 20. Although the bearing end of the swivels lift and seat, the rocker design of the swivels, the fulcrum studs and the springs 38, keep the swivels in bearing contact at all times. The swivels gradually descend to bearing position on the pliant

tire 46. The only purpose of springs 38 is to prevent the swivels from rattling. When a swivel is bearing the direction of the load on the inner side is the same as the coexistent direction of axis 4, so that the load stress on the bearing swivels is pure compression and springs 38 have no function other than to tighten the swivels. The swivels will seat and bear without the springs or the fulcrums, however the hydraulic currents cause an audible click that is remedied by springs 38.

In review the preferred embodiment is a heavy duty transmission, having a stepless range from neutral to 3 to 1 overdrive, and capable of driving in ratios lower than 150 to 1 underdrive. The extreme internal material stresses caused by this unusual reduction and generation of output torque is carried by the substantial increase and distribution of the load bearing points in the power train, and the absence of shock loads, due to the stepless ratio change.

The diametrical gearing according to the present invention is quite different in mechanical principle than that of conventional gearing. When input driven planet gear teeth of the present invention are rotating an output driving ring gear, while they are reciprocating on diameters of the ring gear, many new and desirable gearing arrangements and functions are made available. For example, a typical and conventional gearing arrangement of an automobile transmission involves internal planet gearing that multiplies the input turbine torque three or four times to provide the bwest reduction, and generate the maximum output torque. Of course, this limited low gearing also limits the use of overdrive gearing. On the other hand, the present invention, using diametrical gearing and a simple two gear arrangement can multiply the input torque more than a hundred times permitting extreme overdrive gearing that can extend a stepless range from neutral to more than three to one overdrive at the output shaft. Another example of the superiority of the diametrical gearing system is that the planet gear axis may be driven, on its orbit, directly, by

the engine shaft , while the planet gear axially disposed teeth are restricted by the input turbine to provide a stepless change of ratio. Due to this and the extreme reduction that can occur at the diametrical mesh between planet gear teeth 8 and output ring gear 2, a very small part of the power train goes through fluid connection between the pump and turbine as opposed to that of a conventional automatic transmission. Yet another example of the exceptional ability of the diametrical gearing is the load bearing potential of the power train. In the preferred embodiment and variation B, literally all of the planet gear teeth 8 are drivenly meshed at all times. In variations A and C at least half of the planet gear teeth are drivenly meshed at all times. The driving teeth can address driveri ring gear 2 at various angles which provides extreme mechanical advantage. However, in the gearing of conventional transmissions all gear driving occurs in a tangential direction and no reduction occurs except the reduction that is related to the difference in gear sizes. Also, the load bearing strength at the mesh between any two gears is limited to the beam strength of one or two teeth. In short, a single planet gear working in the diametrical gearing system of the invention will carry more load than several comparable planet gears in a conventional gearing system.

In review, a direct mechanical input drive, from the engine, rotates planet gear axis 6 on its fixed orbit 7 in a clockwise direction, the planet gear 1 is meshed with an output ring gear 2, and this mesh tends to rotate the planet gear in a counter clockwise direction around its axis 6 while planet gear teeth 8 reciprocate on diameters of the ring gear, restriction on the rotation of teeth 8 tends to curve their path and the diameters of the output ring gear must rotate accordingly. Diametrical gearing can provide more reduction and torque with two gears than it is practical to attempt in conventional gearing with any number of gears.

The three elements that are essential to the function of the present invention are (1) an input driven PLANET GEAR with teeth reciprocating on a diameter of; (2) an output driving RING GEAR; and (3) A COMPONENT (restrictor) to restrict the rotation of the planet gear teeth. All three elements may vary in number and arrangement to provide an endless variety of transmission designs within the scope of the invention. Of course, an input planet gear with conventional spur gear teeth reciprocating on diameters of an output ring gear could be included in these variations. However, it is- characteristic of a conventional spur gearing mesh that only one or two teeth provide all of the drive for a mesh during any point in time. In the preferred embodiment of the present invention all of the axially disposed teeth are driving at all times in order to carry the extreme load that occur from the phenomenal reduction that is provided. In variations A and C, at least one-half of the axially disposed teeth are driving at any time, and all teeth remain in driving contact at least half of the time. In the preferred embodiment and variation B, all of the axially disposed teeth are driving all of the time.

An essential function of the invention is the confinement of an input planet gear teeth to movement on a straight line that is a diameter of output driving ring gear 2. This straight line motion is immutable as related to the ring gear 2. When the motion of planet gear teeth 8 is also on a straight line as related to a fixed reference, there can be no rotary drive put on output ring 2 so the transmission is in neutral mode, the other essential function of the invention is to curve the path of teeth 8 as related to a fixed reference thereby forcing output ring gear 2 to rotate, to maintain the immutable status of teeth 8 confinement to the ring gear diameters. The rotation of output ring gear 2 is related to the curve of the input driven planet gear teeth 8, as related to a fixed reference. For example, the slightest curve of teeth 8

forces gear 2 to rotate accordingly. This method of power transmission provides a stepless ratio change along with more reduction than any gearing ratio change along with more reduction than any gearing method previously reported.

Variation A omits the entire third gear 3 mechanics. This includes carrier block 89, crank 33, control unit 9, third gear 3, swivels 12-20, seat 10, tire 46, piston 11 , balls 99, bearings 57, 58, 62, 59 and 61 , valves 74 and 71 , and other supporting parts such as springs 38. Although the omission of the third gear mechanics minimizes the elements of the invention, it gives up the positive mechanical driving aspect of the invention as provided by the third gear mechanics in the preferred embodiment. Although part of the drive train in Variation A is fluid connected, it is far more efficient than any conventional power transmission especially where a conventional power torque converter is used. A conventional automobile power transmission using a torque converter can multiply the input turbine torque 3 or 4 times with its internal gear reduction, to provide the highest output torque, necessary for functions such as starting the vehicle. In Variation A, however, the input power train comprises a positive mechanical input drive to rotate axis A6 of the two planet- gears A1 and A1A on orbit A7, and restrictor A21 provides a force to curve the planet gear teeth A8. Reductbn occurs between the input and the output, by and according to the path of teeth A8. A very slight curve in the path of teeth A8 can multiply the input torque of the input turbine A78 by more than a hundred times. Inversely, a very slight input torque from the input turbine A78 will start the vehicle moving. Since the ratio change in Variation A is stepless and bad oriented, very little inertial load occurs. If the output load increases, the path of teeth A8 will naturally evolve toward straighter patterns and lower the transmission ratio accordingly; the operator may increase the input RPMs to maintain constant speed. Variation A is automatically in the highest ratio that is

drivenly compatible with the output load and the input power. As shown in figure 19 variation A indicates how plurality of the first essential element may be implemented.

The first essential element is sometimes called the first gear 1 , and sometimes an input planet gear 1. In figure 12 these two gears are marked A1 and A1A. Variation A also shows a transmission design without overdrive pinions and the highest input to output ratio is 1 to 1. Although the restrictor A21 appears to be similar to a conventional torque converter, the implementation of the two is quite different. In the conventional torque converter the turbine contains, all the drive between the input and the output, however, restrictor A21 of the present invention restricts the counter clockwise rotation of teeth A8, as opposed to driving, while the engine input shaft provides a direct mechanical drive to rotate axis A6 of planet gears A1 and A1A. Another important difference in the conventional converter and the present restrictor is that the restrictor turbine turns much slower as related to the pump than the converter turbine. This occurs in the variation with overdrive gearing.

Variation B is similar to the preferred embodiment except that restrictor 21 is omitted. All parts in variation B have corresponding parts in the preferred embodiment. The counter clockwise rotation of input driven planet gear 1 around its own axis 6, is restricted by a reaction force from the housing tube 30 via seat 10, swivels 12-20 and the third gear guide channels. Referring to figure 7 third gear axis 4 is shown, pushed away from axis 5 and driven along its orbit 22, by input forces. In this variation there is a positive mechanical connection between the engine and the vehicle wheels except when the vehicle free-wheels away from the drive. When a first gear tooth 8 moves in the diametrically disposed channels of the second and third gears, the mechanics is similar to a wedge action; if a tooth 8 moves 10

millimeters on a second gear diameter while the second gear pitch circle moves 1 millimeter in a tangent direction, the input torque is multiplied 10 times in a tangent direction, the input torque is multiplied 10 times at the second gear. The stepless radial movement of third ^' gear axis 4 steplessly increases the transmission ratio as fast and as smooth as the vehicle's inertial resistance is converted into momentum. The transmission ratio, and ratio between the engine and the vehicle wheels, changes simultaneously, this is why phenomenal acceleration can occur without spin-scratching the vehicle's tires. If no other force except the input drive intervened, all points on third gear 3 would move on an orbit exactly the same as orbit 22 of third gear axis 4. However, a reaction force from the housing does intervene when the sprag action of swivels 12-20 blocks any counter clockwise motion as related to the housing 83. A transitive point on working side 42 of third gear 3 that is in line with axis 4 and axis 5, is always held still by swivels 12-20 at the instant that the alignment occurs. This geometrical arrangement forces an outer terminal point of a third gear diameter to rotate approximately the same distance that axis 4 moves on orbit 22 during a coexistent time. The side where this hold action is occurring is working side 42 and the opposing side of the transmission is riding side 43. Since the third gear diameter is forced to rotate and first ger teeth 8 is confined to movement on the third gear diameter, teeth 8 must curve, as related to a fixed reference. Since the third gear cannot rotate counter clockwise because of swivels 12-20, the output second gear 2 must rotate clockwise a distance similar to the distance that axis 4 moves on orbit 22; if the diameter of orbit 22 is one-tenth the diameter of the second gear 2, the output second gear 2 will rotate 36° while input shaft 31 rotates 360° and the input torque is multiplied by ten at the output second gear 2. The transitive point held still at the instant, is materially intangible and moves at input RPMs, however the tangible second and third gears rotate one-

third the RPMs as that output shaft 28. Whereas, the internal motion of the transmission system is relatively slow.

Variation C is enclosed within a cylinder shaped housing C83 that comprises a central tubing part C30, an input head part C49, and an output head C92. This three piece housing C83 is bolted together with bolt C93. The input head C49 supports a rotatably mounted input shaft C31 via bearing C50, and the- input shaft C31 is fastened to and part of carrier C32 rotatably mounted on the second gear C2 via bearing C55. Gears C1, C24, C25, C66 are rotatably mounted in carrier C32. The pump C79 is milled into the input face of carrier C32. The turbine side C78 of restrictor C21 is connected to gear C26 rotatably mounted on housing C83 and second gear C2 via bearings C53 and C94. Gear C26 meshes with gears C24 and C25. Gears C25 and C66 are fastened together and supported by axle C120. The first gear C1 is fastened to gear C24 and both are supported by bearing C51 and C54. Balance gear C66 meshes with gear C67 fastened to and part of second gear C2. Split piston and lock balls C69 are set in housing tube C30. The first gear C1 is diametrically meshed with second gear C2 rotatably supported by bearings C57 and C37. The output shaft C28 is rotatably supported by bearings. C65 and C63. Overdrive pinions C27 are rotatably mounted on studs C84 of head C92, via bearings C64. Stator C80 is rotatably mounted on housing head C49. Stator tack piston is set in head C49. Binary valve C70 is hydraulically connected tb restrictor C21 and stator lock C68.

Binary valve C72 is hydraulically connected to the transmission interior. Binary valve C73 is hydraulically connected to lock piston C69.

An endless variety of computerized driving programs, with different degrees of automation, may be consistent with the present invention. For example, in variations A and C, the ratio changes automatically and simultaneously with the input RPMs; the transmission automatically and steplessly seeks the highest ratio for any

combination of input RPMs with the output load. The operator's dashboard equipment for variation C requires only three buttons: reverse, neutral and forward along with a conventional accelerator.

A vehicle is started in the neutral mode and when forward is indicated by the forward button the vehicle will move regardless of the lowest of input RPMs because of the reduction that is provided by the reciprocation of teeth 8 in the second gear channels. As the input RPMs increase, the transmission ratio moves simultaneously and steplessly, through infinitely low ratios up to the highest ratio permitted by the output load, the increase in input RPMs in correlation with the stepless evolvement of the transmission ratio provides a very desirable driving performance. If the output load permits, the transmission can continue driving up to 3 to 1 overdrive. The overdrive pinions C27 make the extremely low ratios that are inherent to the present systems more practical.

The only binary valves that are required for the operation of the variations A and C are valves 70 and 72 for cooling and neutralizing restrictor C21 during the reverse and neutral modes, and valve 73 for the reverse and downhill brake modes. the forward mode signal activated restrictor C21 by increasing its oil volume and locking stator lock C68 via opening valve 70 to high pressure. A small amount of cooling oil flows between the pump and turbine, through the transmission, and out the valve 72. The larger flow through valve 70 provides the necessary volume build-up, in the restrictor, to provide the forward mode.

The preferred embodiment, and variation B implements a positive mechanical drive, as opposed to fluid dynamics, and the input-output ratio correlates with the position of the third gear axis 4 that further correlates with the position of pistons 29. Because of this, the stick and dial method is indicated as the control method for the preferred embodiment.

in variations A and C, a very slight force on teeth 8 will cause the vehicle to creep, because of the extreme torque multiplication that occurs at the second gear channels. Whereas, a neutral button signals a neutral mode that opens valve 70 to bw pressure and valve 72 to high pressure. Valves 70 and 72 work opposite and under the same signal. The low pressure on line 70 releases stator C80 via lock C68 and also decreases the restrictor oil volume to provide the neutral mode.

During this neutral mode the reverse button may signal valve 73 to open to high pressure and lock gear C26 via piston C69 to provide the reverse-mode, the reverse mode is fully mechanical and is not driven by the restrictor C21. . - The forward signal button opens valves 72 and 73 to low pressure and valve

70 to high pressure to lock stator C80 via lock C68, and to increase the restrictor oil volume. The stepless and efficient increase in forward input-output ratios is automatic because the system inherently seeks the highest ratio that is driveable by the coexistent input torque. The engine accelerator steplessly controls the transmission ratio, for a given load, at the same time that it changes the input RPMs. it is emphasized that the various pressure locking devices 69, 68, and 11 have no similarity to the multiple friction clutches that are inherent to the conventional planetary type power transmissions, the conventional clutches engage during high speeds and must rub to damped the shock caused by large gaps between the driving ratios. The bcks 69, 68, and 11 of the present invention engage when the parts are relatively still, and they are designed to hold on contact as opposed to the rubbing contact of the conventional clutches.

In the operation of variation C, input shaft C31 is connected directly to the power source and fastened to carrier C32. This shaft-carrier unit is supported by input head C49 and second gear C2 via bearings C50 and C55. the carrier rotates first gear axis 6 and gear C66 axis on a fixed orbit C7. the carrier is fastened to, and

drives, pump C79 at input RPMs. Power from pump C79 and stator C80 is transmitted via fluid medium to turbine C78 fastened to multipurpose gear C26. the gearing indicated that gear C26 rotates about one-third the RPMs as that of the output shaft C28, and during the low staring ratios, the difference in the pump RPMs and the turbine RPMs is extreme, so the torque factor of the pump power is substantially increases at the slow turning turbine C78, and consequently at the multipurpose gear C26. This increased torque at gear C26 tends to restrict the rotation of the teeth of gears C66 and C1 around their respective axis, via meshing contact with gears C24 and C25, fastened to gears C66 and C1. that is, gears C66 and C1 are driven at their axis around fixed orbit 7 by a direct mechanical input drive, and also restricted at their teeth by a fluid generated torque from turbine C78 via gears 24, 25, and 26. The diametrical gearing between the first gear teeth C8 and the diametrical channels in the second gear C2 is similar to the corresponding gearing in the preferred embodiment. However, the path pattern of teeth C8, is changed by the force resulting from the mechanically driven axis C6 coupled with the turbine force on teeth C8, in addition, third gear 3 mechanics are omitted. The resulting force, together with the output load registered at the second gear C2 channels, determined the path patterns of teeth C8 to determine the input-output ratios. In other words, the input-output ratio and the stepless change of the ratio, is bad oriented. If the load is such that the aforesaid forces on teeth C8 and axis C6 can curve the path of teeth C8 only one degree, away from a straight line, relative to the housing, while the input shaft C31 makes a full 360° revolution, then the output second gear C2 must rotate one degree to provide a ratio of 360 to 1 underdrive between the input and the output second gear C2. Since this variation C has the 3 to 1 overdrive gearing at pinions C27, the actual ratio between the input shaft and the output shaft is 120 to 1 underdrive. As the output load reduces relative to the input

power, the path of the teeth C8 evolves toward more elliptical, rounded patterns and the input-output ratio goes upward. The stepless range of this variation C design is from neutral to 3 to 1 overdrive. If the load increases, the path of teeth C8 will steplessly evolve toward more accurate, straighter patterns as the input-output ratio moves steplessly toward lower ratios as required by the load, and the input is increased to maintain constant speed.
