FIELD OF THE INVENTION
The invention refers to the transducers accumulating compressed air energy by the use of human muscle strength or by the use of kinetic energy of the bicycle that conduct that energy to the bicycle at that moment, which have the possibility also to accumulate energy from an external source, for example: from an electric engine upon the stoppage of the bicycle.
BACKGROUND OF THE INVENTION
A bicycle with the use of compressed air energy is well- known, which has a compressor and an engine connected with the propulsor of the bicycle (JP10218075, B62M23/02, 1998). This transducer has a separated from each other compressor and an engine, which complicates and raises the price of the structure. For the realization of the compressor high precision of production is required.
The closest analogy of the invention is the reversible transducer of compressed air energy intended for the bicycle, which has a combined compressor-engine, controlled transmission placed on the frame of the bicycle, which is connected with the compressor-engine and with the rear wheel of the bicycle, control mechanism, which has two levers with control links and a compressed air tank (JP2005035502, B62M1/10, B62M17/00, B62M23/02, 2005).
The shortcomings of the well-known transducer are:
- The low productivity of the compressor, because of which the energy is accumulated slowly and uncontrollable,
-The low efficiency of the engine, which is conditioned with the fact that the air released from the chamber to the atmosphere has still an extremely high pressure, -The low technological effectiveness of the structure, as a high precision is required for the production of parts, because of which the cost price is high.
The task of the invention is:
- Raising the productivity of the compressor through conducting a higher speed of rotation to the shaft of the transducer, as well as ensuring the controllability of the productivity through ensuring the controllability of the speed of rotation of the shaft,
-Raising the efficiency of the transducer in the engine operating regime through conditioning the moment of air inlet with the cam length, thanks to which pressure is inlet in such an extent that the engine can consume more fully,
-Raising the technological effectiveness of the structure and making it cheaper to make the device affordable to the wide range of consumers.

DETAILED DESCRIPTION OF THE INVENTION:
The compressor-engine 1 is placed on the rotary frame 2 (Fig.5 and 6). The working shaft 3, through bearings 4 and 5, is set on the rotary frame 2 in coaxial hubs, with the possibility to turn around the axis 6. The chain wheel 7 is coaxial to the shaft 3, is freely set on the hub of rotary frame 2 from the side of one of its fronts (as is seen also on Fig.3), and from the other front it has an internal toothed hub, which serves to the possibility of being coupled with the coupling 8. The coupling 8 is set on the shaft 3 and has one degree of freedom towards it: it may be moved on the shaft only towards the axis 6. There are external teeth on one end of the coupling 8 to be coupled with the chain wheel 7, and there are two cams on the other end, about which will be spoken later. In case of being coupled with the chain wheel 7, it couples the chain wheel to the shaft 3. There is a circular slot in the external surface of the coupling 8, in which is placed the half-washer 9 with the possibility of slipping, which has two axial lugs to be joined with the fork lever 10 hingly. The fork lever 10 is hingly set on the axle 11 of the rotary frame 2 and serves to the movement of the coupling 8 towards the axis 6. Cone-shaped discs 12 and 13 are placed on the end of the shaft 3, the 12 of which is affixed firmly. The disc 12 has a hub with external ball grooves, and the disc 13 - internal. The discs can be coupled to each other th rough bails 14, with the possibility of rolling friction movement of the disc 13 towards the axis of the disc 13. The discs 12 and 13 are pressed to each other through a spring plate 15. The rim 16 affixed on the rear wheel passes between the discs 12 and 13 as shown in Fig.7-9. The disc 12 may also be movable, but in that case it must have its spring (is not shown in the drawings). The other head of the shaft 3 is made in the form of the eccentric, on the role and importance of which will be spoken later.
The axle 17 is firmly affixed to the frame of the bicycle (Fig. 3, 4, 5) and serves as a swing axle for the rotary frame 2. Also the sheath of rope 19 coming from the control lever 18 (Fig. 1) is affixed to the frame of the bicycle, and the head of the rope is affixed to the rotary frame 2. The rope 19 serves to the realization of the rotation of the frame 2, in the result of which the discs 12 and 13 cooperate with the rim 16 or are separated from it through the pull back spring 20. The sheath of rope 22 coming from the control lever 21 (Fig.l) is affixed to the frame 2 and the end of the rope is affixed to the head of fork lever 10 (Fig.2, 3, 5). The rope 22 serves to the rotation of the fork lever 10 around the axle and to the movement of the coupling 8 towards the axis 6. The spring 23 serves to the return of the lever 10 to the initial position.
The tank 24 serves as storage for compressed air and simultaneously as the main frame of the bicycle. To supply the tank 24 from an external source, for example from the electric engine, an electric engine 26 is coupled on the plate 25, besides the plate 25 is affixed to the frame of the bicycle, and the exit shaft of the electric engine is coupled to the disc 12 as shown in Fig.10.
The structure of the compressor- engine 1 is as follows (Fig.3 and 13) :
The eccentric 27 of the shaft 3 serves to conduct backward- forward movement to the pistons 28, 29 and their bracket 30 through the connecting rod 31. The cylinders 32 and 33 are positioned with their flanges opposite, and the valve units are placed between the flanges, forming a cylinder-valve block, which is affixed by the flanges to the lower cantilever beams of the rotary frame 2. The valve units is composed of the plates of contact with the atmosphere 34 and 35, the valve plates of compressed air 36 and 37, as well as the seats 38 and 39 of valve plates. The valve plates of atmosphere 34 and 35 are connected with the cam 40 operating them through fork lever 41 and through the rolls 42 and 43 set on its ends with the possibility of free spin, besides the lever 41 is hingly set on the axle 44 of the rotary frame 2 and with its other end it is connectively joined with the opening lever 45, which has a possibility of rotation by the small angle of its axle 46. The valve plates of compressed air 36 and 37 are connected with the cam 47 operating them through fork lever 48 and roll 49 and 50 set on its end with the possibility of free rotation, besides the lever 48 is connectively set on the axle 51 of the rotary frame 2 and is hingly joined with the opening lever 52 with its other side, which has a possibility of rotation by the small angle of its axle 53. The possibility of rotation of the axles 46 and 53 by the small angle may be realized when they are placed on the base 54 with flexible material, for example retina, filled in the two pits 55 and 56. The base 54 has also a hole 57 for the contact with atmosphere and an exit for the contact with the tank 24 through the tube 58. The compressor-engine is enclosed in a case 59 that has a door 60. The case 59 serves also as lubricating tank of compressor- engine (crankcase).
The transducer may operate in 4 operating regimes: compressor's, engine's, idler's and external power source.
Below is presented the description of those four operation regimes :
1. (Fig.1,2, 7) in case of necessity to brake the movement of the bicycle or in case of wanting to change energy, the bicycler presses the lever 18 and makes a frame 2 rotation through the rope 19. In the result of it the discs 12 and 13 touch the rim 16, forming friction transmission. In case of increasing the force on the lever 18 the rotary angle is increased, the rim 16 gets closer to the axis 6 and touches the discs in the range of smaller diameters of them, in the result of which the quantity of transmission is increased, and the shaft 3 rotates quicker. Simultaneously the spring plate 15 is pressed more and its effect of force is increased. It follows from the mentioned that the biker has a possibility to choose the wanted speed of making the movement slower (negative acceleration). As per the presented sketches, the operation of the lever 18 is made by hand, but the rotation of the frame 2 may be realized also by other means, for example by foot lever. Thus, in compressive operating regime the operation chain is as follows: rim 16 - discs 12 and 13 - shaft 3 connecting rod 31 - compressor 1 - valve unit - tube 58 - tank 24.
2. (Fig.1,3, 8) In case of necessity of using the potential energy of compressed air in the tank 24, the biker moves (for example: pushes with his/her thumb) the lever 21 and conducts a rotation to the lever 10 through the rope 22 around the axle 11. In the result of this, the half-washer 9 moves the coupling 8 towards the axis 6 and couples it with the chain wheel 7 at first, later positions the cams 40 and 47 under the fork levers 41 and 48, operating the valve units. Thus, the operation chain in the engine operating regime is as follows: tank 24 - tube 58 - valve unit - engine 1 - connecting rod 31 - shaft 3 - coupling 8 - chain wheel 7 - carrying element of the bicycle - rear wheel of the bicycle. In the presented sketches the carrying element of the bicycle is presented in the form of a chain, but it can be realized also in another, for example in the form of a toothed belt.
3. (Fig.2, 4, 9) In the idle operating regime of the transducer none of the control levers 18 and 21 is pressed: discs 12, 13 - rim 16 friction transmission is not operated by the coercion of the spring 20, and the coupling 8 - chain wheel 7 couple is not operated by the coercion of the spring 23. The chain wheel 7 freely spins with the carrying element (chain) as an idler wheel. In this operating regime the biker rides the bicycle as a common bicycle.
4. (Fig.10) At the stoppage of the bicycle it is possible to couple the transducer to the external power source, for example to the electric engine, which will spin the shaft 3 and will operate the transducer as a compressor charging the tank 24. In this operating regime there is no need to press the levers 18 and 21, and the rear wheel of the bicycle does not spin. In the presented sketches the plate 25, with the electric engine 26 placed on it, is affixed on the frame of the bicycle, and the exit shaft of the electric engine is coupled to the disc 12 through holes 61. But the coupling of the transducer to the external source is possible to make also by other well-known means.
As the cylinders 32 and 33 are positioned oppositely and are affixed to the frame 2 and the pistons 28 and 29 are placed face to face in the general bracket 30 which makes a backward- forward movement, then the work of the compressor-engine is two-cycle both in compressive and in engine operating regime.
In the compressive operating regime, each of the pistons, moving away from the valve unit, makes an air intake by the passage connected with the atmosphere 57, and approaching to the valve unit, makes a pumping of the compressed air towards the tank 24 through the tube 58. When the first of the pistons makes an intake cycle, the second makes an pumping cycle and vice versa. The cycles follow one another each 180° of the rotation of the shaft 3.
In the engine operating regime the compressed air tank 24 is acting as an energy source in the engine operating regime, which is connected with the valve unit by tube 58.
Each of the pistons makes the cycle of moving from the valve unit by the coercion of the compressed air, and during the cycle of approaching, used air is pumped to the atmosphere. The contour of the cam 47 is chosen so that for the inlet of the compressed air into the cylinder 32 or cylinder 33, the corresponding va!ve plate (36 or 37) is kept open during about 50° rotation of the cycle, and the remained 130° rotation is made by the inlet air energy, which conditions the high efficiency of the engine. The contour of the cam 40 ensures the successive opening of the plates 34 and 35 to outlet the used air into the atmosphere during the corresponding cycles.
The case 59 serves also as crankcase: the oil poured on its floor, thanks to the backward-forward movement of the bracket 30, is dispersed and lubricates and cools down all the moving parts of the compressor-engine.
