Field of the Invention

[0002] The present invention generally relates to the field of variable helical traction or helical propulsion.

Background of the Invention

[0003] There presently exists very few industrial solutions for helical drive propellers besides undedicated examples and applications in inspection piping and pipeline pigging wherein transportation by means of opened tubular pipes and tubes longitudinally in length as rails is considered. It is proposed herein that an innovative and efficient helical propulsion systems would render said transportation means far more desirable.

Summary of the Invention

[0004] The shortcomings of the prior art are generally mitigated by a progressive helical traction and/or propulsion drive shaft acting as a continuously variable transmission system which can actuate either: a combination of helically actuating angular wheels to linearly actuated angular wheels about the inside of a tubular shaped rail while having both firstly a rotational plane radial to a drive shaft’s central axis of rotation and secondly a rotational plane from within the central axis of rotation of a mechanised and motorized drive shaft; including possible inclusion of a helical to linear propulsion drive shaft capacity with the same rotational plane combination previously described for angular wheels respective to drive shaft but with the inclusion of aligned capacitors or aligning inductors being respectively field actuated or field inducted, or field actuating or field inducting, about a tubular guide shaped field or shaping field from a guiding rail following a pattern made for combination of variable helical traction or propulsion with angular wheels.

[0005] In this aspect, the inventive drive shaft is modular, variable, scalable and industrially suited for industrial production and industrial use. Its inventive design is essentially multi- configurable and practically endlessly modulable and combinable in order for the inventive drive shaft system’s design to execute its main purposes being to provide both the function of a progressive traction and/or propulsion helical drive shaft system and the function of a continuously variable helical transmission.

[0006] In another aspect, the invention is said to be industrially modular because of its ability to be configurable into various displays and layouts of helical drive shaft designs which are variable namely in the dimensions, lengths, diameters and shapes, motorization and actuation. It is also modular and variable following namely the number of angular wheels or alike aligned capacitors or aligning inductors, the number and intercalating alternance of angular wheel rows or alike aligned capacitor or aligning inductor rows. It is also modular and variable following the number of drive and propulsion shafts being combined according to a displacement device attaching the helically driven shaft and thereby forming part of a transportation system functional unit of which the live load is being thereafter distributed and carried by means of the tubular railing assemblies where are comprised helical to linear displacement fields. It is modular and variable in order to suit any specific transportation function from being displaced by at least one transportation functional unit based on such drive shaft combinations and mostly. It is modular and variable so that all angular wheels or alike aligned capacitors or aligning inductors can variate and be assembled in order to be operated in respect to a given linear direction of the drive system with its transportation device with any given transportation functional embodiments and the functional unit configurations.

[0007] In another aspect, the inventive drive shaft is said to be functionally and industrially scalable because its design can be produced massively and thus from a simple and central assembly of miter gears, for example, associated per angular wheels, or alike mechanism, which can be scaled altogether with potential variations of dimensions of the diameter of the angular wheels and of the aligning inductors according to the internal diameter of the tubular rail assemblies or displacement fields.

[0008] In another aspect, the invention is said to be an industrial continuously variable helical transmission because of its simplicity. Indeed, the solution as described in the patent revolves around a simple design which implies at least one single drive shaft to actuate at least two intermediate and counteracting and engaging actuating elements. In the design, there is one central external fixed drive shaft bushing with a straight groove in the length of the drive shafts axis of rotation for the drive shaft’s translation within the axis of rotation of the drive shaft. In the design, the drive shaft is solidary to the drive shaft rotation in its axis or rotation, which receives at two places - being the respective endings of one actuating stud solidary perpendicularly with the drive shaft-, and whose function is to make the drive shaft solidary with the drive shaft’s axis of rotation. In the design, there is a central intermediate actuating element being immediate to the drive shaft, and between the later drive shaft centrally and the said central exterior fixed drive shaft bushing, there is an actuating cylindrical bushing with a helical groove engaged with the said actuating stud solidary perpendicularly with the drive shaft whose function is to: firstly, engage into a central miter gear; secondly, engage towards an angular wheel swiveling caster’s miter gear and, thirdly, to rotate it from in the axis of rotation of the drive shaft at a 90 degree angle in order to, fourthly, articulate and define directly a variable position of angular position of at least one actuating angular wheel’s miter gear or aligning inductor within an axis of rotation being radial to the central axis of the drive shaft, and; lastly, in order to generate the said continuously variable transmission function with angular wheels or aligning inductors engaged rotationally about the axis of rotation of the said drive shaft and made variably rotational radially to the axis or rotation of the said drive shaft to generate an infinitely progressive and variable helical drive displacement along tubular rail assemblies or displacement fields. In the design, the infinitely progressive and variable helical drive is operated along in a driving linear direction defined from a standpoint relative to an either clockwise or counter clockwise rotation of the drive shaft axis of rotation relative to the angular wheel’s and aligning inductors’ angular position within the internal diameter surface of the tubular rail assemblies. The internal diameter surface of the tubular rail assemblies constitutes and provides the main traction and propulsion cylindrically helical moment of force’s orientation plane of engagement or along through the displacement and induction field’s differentiating direction of electromagnetic and superconducting potentialities.

[0009] The inventive design achieves the function of the progressive linear speed and direction drive and as such by a variable transmission of the angular position of actuating and actuated elements, which will be explained in greater detail in the present application.

[0010] In another aspect, the invention is dedicated to the development of a modular, variable and scalable helical drive transmission mechanical solution which allows a resistance-free and continuously variable control of the angular orientation of at least one angular wheel’s swiveling casted located about an axis of rotation radial to a rotative support shaft’s axis of rotation and about which swiveling casters holding the angular wheels rotate about the central axis of rotation of the said rotative support shaft to generate a helical traction or propulsion.

[0011] Thereby, in another aspect, the invention can be said to be a modular, variable, scalable and industrial helical drive transmission engaged with a shaft design for angular wheels located along the length of the drive shaft into angular row designs, mostly intercalated angular row configurations for optimal distribution of helical traction, propulsion and transmission.

[0012] Thereby, in another aspect, the invention allows modular, variable, scalable and industrial helical driving transmissions to be driven within and along tubular shaped rails designed with an open circular cross sections which, by means of the drive shaft’s displacement device holding the drive shafts rotationally and transmitting the load carried outside the tubular rail, beholds the central transmission shaft’s axis of rotation in such way to allow the angular wheels’ swiveling caster configured around the drive shaft to define the helical angular position variably and radially about the axis of rotation of the drive shaft in such way that the angular wheels can free rotate freely about their own axis of rotation while additionally being rotating about the axis of rotation of the drive shaft.

[0013] Thereby, in another aspect, the invention allows the displacement of goods and people along the path set by an open circular cross sectional rail assembly and within which the driving transmission translates and transmits mechanically the relative directions of resistances of the angular wheels’ position to generate helical traction translated into a linear displacement of a helical drive system.

[0014] In yet another aspect, the invention discloses the engaging of at least one angular wheel’s swiveling caster which is engaged in at least one opposing side of at least one swiveling caster in order to transmit and combine variably either clockwise or counter clockwise the required force moments, said opposing force moments, simultaneously and solidary with at least one common drive shaft and at least two intermediate and counteracting and engaging actuating elements.

[0015] In this aspect, the constituting rationale of the invention is firstly (1) to combine with engaging and solidary made actuating elements to at least one progressively driven, continuously variable and helically engaging angular wheel for its resistance-free variation, and secondly (2) with a design which is solidary and is not affected by the rotational force and inertia when at least one progressively variable and helically drivingly engaging angular wheel system is rotating about the axis of rotation of the central transmission shaft system and rotating about a radial axis to the axis of rotation of the drive shaft, and thirdly (3) to progressively variate the driving control in both terms of linear speed and of linear direction in such way that there is no variation of resistance applied to a main actuating drive shaft when the at least one angular wheel is drivingly engaged by the central transmission shaft system variably along the linear direction set by its natural displacement path defined as a helical motion and/or traction and/or propulsion pattern along the inner surface of a tubular shaped rail and/or along a linear to tubular driving tubular shaped rail, environment or field for helical propulsion.

[0016] In another aspect, the invention allows an innovative drive shaft and multiple actuating members defined with at least two intermediate and counteracting and engaging actuating elements centrally actuated by the said central drive shaft’s actuating studs. The design is inventive as it allows a multiconfigurational and logical design which consists in modular rotational swiveling caster units, pairs and so forth forming angular wheel rows, and thus engaging within the central axis of rotation of the drive shaft, indirectly with a drive shaft’s translational movement while within being solidary with the rotation plane of the drive shaft by means of straight grooves internally solidary to the drive shaft and into which the drive shaft’s perpendicularly oriented and solidary actuating studs can translate along longitudinally the axis of rotation of the drive shaft in order for at least one helical groove bushing’s rotational actuation while surrounding the drive shaft and around which there’s a drive shaft or straight groove bushing’s internal surface with a said straight groove longitudinal in the axis of rotation of the drive shaft and grooved internally from and comprised with at least one to two straight grooves engaged with at least one drive shaft’s actuating stud, which by being actuating the helical groove from being translationally across the helical groove of at least one central rotative helical grooved bushing, allows and constrains the helical groove bushing to rotate while being solidary and engagingly geared from one of its cylindrical side edges to control neutrally, without resistance or variation of any given resistance as aforementioned, the combined and opposed force moments required for having at least one angular wheel swiveling caster variate from the underneath described interacting mechanism relating to the drive shaft movement, which located section underneath the swiveling caster is engaging with an engaging gear, as well in rotative in the radial axis of rotation to the drive shaft’s axis of rotation, with one or both its sides interacting directly with at least one helical groove bushing’s geared and engaging gears being intermediate between the drive shaft and drive shaft and which is counteracting with the actuating stud which is engaged translationally by the drive shaft actuation located centrally and within the inventive design drive shaft.

[0017] In another aspect, the invention further fills the room left for an industrially viable solution that enables the angular variation of angled wheels and other applicable helical propulsion systems. As well, the invention supplies the industrial requirements and demand for a helical drive system and transmission design contributing to alternative and innovative designs for a modular variable drive shaft helical drivers and propellers’ drive shaft for infinitely progressive drive and continuously variable transmission that can be energy efficient and that can give way for a compact design to limit the inertia of the drive system, assure a smooth transmission variation of at least one to multiple sets of wheels compacted in the length of the rotor, and allow a maximal diameter of angular wheels for their lowest possible rounds per minute at higher speeds of rotation for a given round about the axis of rotation of the central transmission shaft in a tubular rail assembly with the outer diameter of the drive system defined by the angular wheels external edges and the inner diameter surface of a tubular rail assembly, both of which diameters are meant to be as optimally corresponding and engagingly fit as possible to allow an optimal angular wheel and central transmission shaft helical traction.

[0018] In another aspect, the invention further fills the room left for a variable pitch system that can variate along 180 degrees in respect to the degree of freedom of rotation of angular wheels set from a radial axis of rotation in respect to the axis of rotation of their support member being the central transmission shaft, in order to produce a progressive linear direction inversion at a continuously variable transmission rate, and with having the ability to progressively switch continuously and inversely the linear driving direction and the driving speed longitudinally along the axis of the rails. In this aspect, the angular wheels can be said to drive the direction and to determine the drive direction speed respectfully progressively and continuously from minus 90 degrees to plus 90 degrees, with having a middle angular position set at 0 degree to define an idling speed or a said stationary stopping of the drive system from its linear speed from either direction defined by the angular wheels in respect to the linear direction determined by the longitudinal driving orientation of the tubular rail assemblies and in respect to the direction of rotation of the central transmission shaft in its axis of rotation. [0019] Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

[0020] The aforesaid and other objectives of the present invention are realized by generally providing a modular design for a main drive shaft drivingly engaging progressively at least one continuously variable angular wheel and/or induction actuators made rotatable around an radial axis to the central axis of rotation of a drive shaft and also made rotatable around the central axis of rotation one the central transmission shaft as a means of helical traction and propulsion system with the possibility of integrating other variable angular propulsion means.

[0021] In one aspect, there is a central transmission shaft in which at least one angular wheel’s angular position is made progressively variable through a mechanical pattern combining and neutralizing at all times the overall force resistance and moments relating to the controlled rotation of at least one swiveling caster of at least one angular wheel, for example, for up to and over a 90 degrees rotation clockwise and anti clockwise by means of at least one drive shaft and at least with two intermediate and counteracting and engaging actuating elements to each sides of at least one swiveling caster of at least one angular wheel.

[0022] In such previous aspect, the invention allows thereby a controlled and resistance-free rotation of at least one swiveling caster comprised solidary of at least one angular wheel, for example, for up to and over a 90 degrees rotation clockwise and 90 degrees anti clockwise, thereby to act a resistance-free and continuously variable transmission in which the rotation of at least one angular caster about a respective axis radial to the central transmission shaft system.

[0023] In such previous aspect, the said pattern can be made configurable with more than one angular wheels at different positions, said sets of angular wheels or sets of helical propulsion means, along the length of the central transmission shaft, with at with at least one drive shaft and at least with two intermediate and counteracting and engaging actuating elements equivalent to reaching two opposing sides of at least one or more swiveling casters of at least one or more angular wheel wheels in order to combine and neutralize at all times the overall force resistance and moments relating to the controlled rotation of at least one or more swiveling casters of at least one or more angular wheels from the at least one main drive shaft and at least two intermediate and counteracting and engaging actuating elements equivalently reaching at least two opposing sides of at least one or more swiveling casters of at least one or more angular wheel wheels.

[0024] In another aspect, the progressive rotation and variation of the angular position and actuating induction defines a helical motion along the inner surface of a tubular shaped rail and the displacement and induction field differentiating direction of electromagnetic and superconducting potentialities relating with the tubular shaped rail which determines both continuously the linear speed and progressively the direction of the linear movement of the drive system as a whole in respect to the longitudinal axis of the tubular rails and the direction of rotation of the central transmission shaft which supports the angular wheels and/or induction actuators as they can reach plus 90 degrees or minus 90 degrees, set from a middle idling position defined as 0 degree in respect of the direction of the axis of rotation of the main drive shaft.

[0025] The features of the present invention which are believed to be novel are set forth with particularity in the appended claims.

[0026] Other and further aspects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

Detailed Description of the Preferred Embodiment

[0065] A novel continuously variable helical transmission system will be described hereinafter. Although the invention is described in terms of specific illustrative embodiments, it is to be understood that the embodiments described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.

[0066] The figures of the present invention are classified in 9 categories of drawings.

[0067] The first category, covered firstly by figures 1 and 2, presents respectively an overall lateral and overall face view of the central drive system 5.

[0068] In figures 1 and 2, there is a central transmission shaft 5 which comprises a main supporting member 4, such as shown in greater detail in figures 3 and 4.

[0069] The main supporting member 4 is a central part of the central transmission shaft 5. The main supporting member 4 supports an assembly of angular wheels 40 and/or aligning inductors 41 onto swiveling casters 35.

[0070] The central transmission shaft 5 comprises on both of its ends of two flanges 10 and 15, respectively on the motor 85 side and on the actuator 86 side.

[0071] The motor 85 can engagingly drive the central transmission shaft 5 either with being solidary with the flange 10 and/or 15 and/or directly with main supporting member 4 and/or the drive shaft 90, such as presented in figure 1, and in greater details in figures 5 to 10.

[0072] The flanges 10 and 15 are comprised of fixation accesses 11 and 8 to secure with screws 20 the flanges 10 and 15 to main central support member 4 of the support shaft 5.

[0073] In figures 3 and 4 the central transmission shaft is made of six rounded grooves said fixation base 6 which allow a rotation within and along of the swiveling casters 35.

[0074] Referring now to figures 1, 23 and 24, there is a displacement device 110 with a central transmission shaft 5 of which the embodiment holds the main drive shaft rotationally by means of intermediate bearing 25. And in the figure 1, there are bearings 25 onto and surrounding the flanges 10 and 15 on each side of the main supporting member to allow the free rotation of the central transmission shaft 5 in the axis 105 of rotation. In that embodiment, the main supporting member is being central and rotational within a guiding tubular rail 115, as shown figures 23 and 24, and also compatible for the displacement and induction fields 125 forming differentiating direction of electromagnetic and superconducting potentialities. [0075] In figures 3, 4 and 8, a swiveling caster fixation base set within through the central transmission shaft allows the swiveling caster to interact and to be secured with a said fixation access 39 and a retaining element 37 acting as a main retaining element.

[0076] In figure 2, the angular wheels 40 or induction actuators 41 are meant to rotate along their axis of rotation 108 relative to the angular wheel axle 50.

[0077] In figures 2 and 24, the angular wheels 40 or induction actuators 41 are meant to rotate along their axis of rotation 105 relative to the central transmission shaft 5; or to be actuated about the L axis of linear inducting centerline and both Y and/or Z axis of radial inducting centerlines. The angular wheels 40 or induction actuators 41 are meant to be interacting with the main displacement moment of force 107. The interaction is being set by the common point of moment of force between angular wheel’s most external diameter 103 interacting with inner surface of rail 115; or the moment of force of the aligning inductor actuating field 125 which allows the displacement induction field variations into differentiating direction of electromagnetic and superconducting potentialities such as defined in figures 25 to 36.

[0078] In figure 8, the retaining element 37 is located around and within the main support member’s fixation base 6.

[0079] In figures 2, 8 and 9, the wheel caster 35 and its bore 38 allow space and holds the angular wheel 40 axel and/or induction actuator 41 location to be solidary with variable caster orientation C in the axis 106 of rotation radial to the axis of rotation 105 of the main support member with the central transmission shaft.

[0080] The angular wheel 40 axel and/or induction actuator component 41 can thereby swivel about an axis 106, radial to axis 105, and remain solidary to main support member 4 of central transmission shaft 5, and rotate and align along in the axis 108 of the axel 50.

[0081] The angular wheel embodiment can be comprised of various and alternative coatings 45 according to the operational helical traction and/or propulsion drive meant to be generated.

[0082] Within and centrally across part of the main support member of the central transmission shaft, is located a flange fixation access of the central transmission shaft 8 for flanges 10 and 15 in relation to fixation access 11 and 8 that can be secured with screws 20.

[0083] Within and centrally across all of the main support member of the central transmission shaft, is located a central bore opening 9 of the central transmission shaft for the drive shaft 90. [0084] About the said bore 9 located within and centrally in the main support member can be located centrally a drive shaft, covered by figures 5, 6 and 7, and covered by figures 8, 9 and 10, around which there is a inventive design for a progressive drive of the angular wheels 40 and/or aligning inductor 41 onto swiveling caster. The design allows a continuously variable transmission of the swiveling casters with a modular and scalable set of angular wheel rows defined by at least one swiveling caster of at lest one angular wheel according to distance and location, such as defined in designs 150 to 157 of figure 12, and designs 205 to 1208 of figures 13 to 22, all defined about a single central drive shaft 90 translational actuation along the central axis 105 of the central transmission shaft.

[0085] The second category, covered mainly by figures 3 and 4, presents respectively a detailed lateral view of the main parts from of the central transmission shaft and an overall face view of the assembly of the angular wheels and swiveling casters.

[0086] The third category, covered by figures 5, 6 and 7, presents the most central and internal embodiment of the invention which allows the actuation of the angular position of the angular wheels and/or induction actuators.

[0087] In those figures of the continuously variable helical transmission system within the central transmission shaft 5, there is translational displacement of the actuating drive shaft 90 with its actuating studs 60, which are rotating solidary within the axis of rotation of the central drive because of at least one straight groove 77 of a central external fixed drive shaft bushing 75. The said at least one straight groove of a central external fixed drive shaft bushing can either be independent or entirely solidary to the central transmission shaft, from which the actuating studs are firsthand located across, perpendicular and solidary with the drive shaft, and which the groove allows the a translational and guided displacement of the drive shaft plane longitudinally along axis 105 while being rotating rotationally around axis 105 within the plane of rotation of the central transmission shaft 5.

[0088] In the embodiment of figures 5 to 10, there are 2 actuating studs and for each, one central external fixed drive shaft bushing around the drive shaft, and the studs are located within part of the flanges 10 or 15, and part of the supporting member of the central transmission shaft.

[0089] There is at least up to 180 degrees of rotation made possible for the angular wheels and according to their casters, in respect to the plane of rotation of axis 105. From the location of actuating stud, around the drive shaft, and from being surrounded and guided by a straight groove of the central external fixed drive shaft bushing being either independent or entirely solidary to the central transmission shaft, the studs can force simultaneously the actuation of a central right cam bushing cage 65 with helical groove 66 or a central left cam bushing cage 70 with helical groove 72, across which the studs 60, when translationally along axis 109 and displaced along longitudinally the axis 105, actuate rotationally such said bushing cage 65 and 72 either clockwise or counter clockwise.

[0090] The rotation of the cam bushing cages 65 and 70 are central and modular in themselves, can vary to carry functions of infinitely progressive drive and continuous variable transmission as described along designs 205 to 1208.

[0091] The design revolves around a modular design suited for intercalated rows 34 of angular wheels 40 and/or aligning actuators 41 constituted of at least one angular wheel 40 in which with each one of the swiveling casters is being engaged respectively left and/or right laterally with a dual configuration and design of intercalated rows 34, This is demonstrated in figures 1 to 10, where in which the central right and left external rotatable cam bushing cage configuration 65 and 70 are respectively solidary with at least one actuating miter gears 80 derived from design 154 and/or 155 of figure 12; and where in which, such as designs 205 to 1208 of figures 12 to 22, there is at least one external rotatable bushing cage 65 or 70 functionally external and oriented respectively towards engaging within part of a solidary miter gear 80 engaging rotationally in the axis 105, on the one of the sides respectively of at least one caster 35. Furthermore, from one of the outer and/or inner limits of the distance and location 99-a and/or 99-b, there is an engagement mechanism made centrally and solidary with at least one miter gear 81, which is thereby made rotational in the axis 106 for the swiveling caster 35 in order to actuate its angular and/or aligning position being radial to axis 105 and engaged on either right and/or left sides respectively to at least one caster 35.

[0092] In respect to the logical layout of the embodiment of the drive shaft 90 displayed with external rotatable drive shaft bushings 65 and/or 70, actuated in respect to embodiment of figures 5, 6 and 7, would consequentially actuate and generate, according the layout of the design 205 to 1208, applicable in all principles for the design as described with the drawings, a variable translational and linear displacement orientation of plane B to the right as defined in the design 205 to 1208 of figures 13 to 22 by DBR. [0093] The fourth category, covered by figures 8, 9 and 10, presents both the central and internal embodiment of the invention which allows the actuation of the angular position of the angular wheels 40 and/or induction actuators 41 and the surrounding embodiment of the central transmission shaft 5.

[0094] From the aforementioned embodiment covered among figures 5 to 10, there is on each external rotatable cam bushing cage 65 or 70, a side which, from the cylindrical edge of the bushing design of cam bushing cage 65 or 70, which is characterized by being formed of as a solidarization interface 66 and 71, respectively engaging solidary a another gear solidarization interface of the central of miter gear of the drive shaft, and thus which actuation actuates at least one miter gear 81 of the angular wheel 40 and/or induction actuator 41 from the miter gear 80 of central right and left cam bushing cages 65 and 70.

[0096] The gear mechanism relating to gears 80 and 81 can be executed with other and equivalent designs, namely either from the interior or the exterior of said gears 80 and 81, and can thus be engaging with other types of gears such as bevel gears and other designs of actuation of the drive shaft 90 such as interacting along with at least one helical grooved rack, bevel gear and pinion.

[0097] The fifth category, covered by figure 11, presents an alternative embodiment design for the central transmission shaft 5 with alike internal design and surrounding embodiment to allows the actuation of the angular position of the angular wheels 40 and/or induction actuators 41.

[0098] There is the embodiment of figure 11 an actuator motor 91 located from the flange 15 and being solidary displacing the drive shaft 90 along longitudinally in the axis 105, but not necessarily also rotating within the axis of rotation axis.

[0099] The sixth category, covered by figure 12, presents the fundamental inventive aspects of the central transmission shaft 5 design from the standpoint of the location of the actuation mechanism relating to the drive shaft 90, and rotative cam bushing 65 and/or 70, and moreover from the distance defined from the location and direction of actuation of the swiveling casters 35 with respect to the aforementioned miter gear mechanism which allows the actuation of the angular position of the angular wheels 40 and/or induction actuators 41, and thus along designs 150 to 157 for modular intercalated possibilities of rows 34 of angular wheel 40 or induction actuator 41 rows defined by at least one swiveling caster of one angular wheel and/or inductor actuator according to a said distance and location 99-a or 99-b.

[00100] The seventh category, covered by figures 13 to 22, presents in the following respective order, designs 205, 206, 207, 208, 209, 210, 211, 212, 405, 406, 407, 408, 409, 410, 404, 412, 413, 414, 415, 416, 417, 418, 419, 420, 450, 451, 452, 453, 454, 455, 605, 606, 607, 608, 609, 610, 805, 806, 807, 808, 809, 810, 811, 812, 813, 814, 815, 816, 817, 818, 819, 820, 1005, 1006, 1007, 1205,

1206, 1207, 1208; which designs present all industrially suitable, inventive and non-evident designs from one row 34 of angular wheels 40 constituted into a one to six, and more, angular wheel 40 and/or inducting actuator 41 row designs along at least a one central transmission shaft 5 design driven in the rotational plane orientation A to the central drive system 5, and being rotational in the axis 106, radial to axis of rotation 105, namely for a displacement device 110 or 112 and embodiment from the designs ranging among 205 to 1208. [00101] All inventive designs of the embodiments ranging among designs 205 to 1208 are always referred to a main design being either 205, 405, 450, 605, 805, 811, 815, 1005 or 1205, which determine the two main functions of the design of the central transmission shaft 5, being the infinitely progressive drive and continuously variable transmission of the angular wheels 40 and/or induction actuators 41 from the actuation of the drive shaft 90.

[00102] The eighth category, covered by figures 23 and 24, presents the device system 110 with central transmission shaft 5 being oriented towards engaging within the axis of rotation 105 of the central transmission shaft 5 which is as well the rail driving orientation. [00103] The central transmission shaft 5 circulates along and through tubular rail 115 and/or displacement field 125 along open circular cross sections of tubular rail 120 and/or displacement field 125.

[00104] The ninth category, covered mainly by figures 25 to 36, present the motorization of the central transmission shaft 5 and the relation with angular wheels 40 angular position variation relative to induction actuator 41 relative to the generation of magnetic flux in displacement field 125. [00105] The rotation A of the central transmission shaft 5 in its central axis 105 and the direction of such rotation, ACW or ACCW, of the central transmission shaft 5, are generally applied and determined from a motorization source 85 or additional motorization source 86 set onto either the central transmission shaft 5 and/or at least one angular wheel 40 and/or at least one induction actuator 41 which can be drivingly engaged for example with a mechanical 85 or induction source 125; and can thereby include portions of the rail 115 and of the displacement and induction field differentiating direction of electromagnetic and superconducting potentialities 125, namely relating with the energy supply of the tubular rail 115 or from displacement device 110 forming with central transmission shaft 5 transportation system, whether direct or alternative current; and can thereby include induction function in and with other portions of a central transmission shaft 5, such as, and not limited to, the main support member 4 as A4, or flange 10 and/or 15 as Al 015, and not limited to, for the main propelling force of the inventive drive system device, which may imply part of the swiveling angular wheel caster and/or aligning inductor-aligned capacitor 35 as A35, the angular wheel 40 and/or induction actuator 41, the angular wheel axle 50 as A50, the angular wheel coating 45 as A45 with induction actuator components, the caster bore for the angular wheel axel 38 as A38, and the retaining element of the swiveling angular wheel caster 37 as A37. Therefore, the drive shaft can be conductive and conducted, and be driven by means of variations of inductive and capacitive reactance to the displacement and induction field differentiating direction of electromagnetic and superconducting potentialities 125.

[00106] Alternative means of supplying the energy for the actuation of drive shaft 5 along within rail 115 and in relation with displacement field 125, can include, and not limited to, the central transmission shaft A4, caster A35, bore A38, wheel and hub A35, coating A40, axel A50, including all other aforesaid potentially actuating components such as wheels, not shown in the drawings, being axial to the rail 115 while being relative and solidary to the displacement device 110, can supply and be supplied directly or indirectly by active and/or passive means such as with, and not limited to, piezoelectrical devices and akin along the rail 115 as A115 and in itself the displacement field device 125 as A125.

[00107] Whether one central drive system 5 is, or is not, directly, or indirectly driven, such as through being only pushed or pulled for example, the progressive variation C of the angular wheels 40 can be of a great interest to execute the function of breaking at 0 degree. In such display, the angular wheels 40 are idling with their axis of rotation 108 being parallelly positioned in respect to the longitudinal direction 105 of the rails 115 and of the central transmission shaft 5 or of a central idling shaft 5 which remains in a stationary moment in respect to the linear speed and linear direction B of the drive system with central transmission shaft 5 and displacement device 110 in respect to its displacement rail 115, and as such, independently of the axial rotation A of the central drive 5 and idling shafts 5 rotational movement in the axis of rotation 105.

[00108] The axial rotation A of the central idling shaft 5 can be progressively reduced to none if the progressive variation C of the angular wheels reaches plus 90 degrees or minus 90 degrees from its middle idling position set at 0 degree. Thereby the angular rollers 40 can be set in a pure progressive idling position when the angular wheels progressively reach plus 90 degrees or minus 90 degrees with respect to their axis of rotation being perpendicularly positioned at 0 degree in respect to the longitudinal direction of the rails 105 and radial 106 to the axis 105 of rotation of the central transmission shaft 5.

[00109] In drawings 25 and 26, and 27 to 30, there are respectively a lateral view and schematic tridimensional view of the design for the drive shaft 5 and tubular rail 115 with displacement field apparatus 125.

[00110] In the drawings 25 and 26, the given alternative embodiments relative to the induction actuator 41 and relative to drive shaft 5 can imply multiple sources and possibilities of induction interaction as being a prime mover actuator, the displacement field 125 being a secondary actuator relative to mover drive shaft 5.

[00111] The prime mover drive shaft 5 can comprised, and not be limited to the drive system device 5, of the swiveling angular wheel caster and/or aligning inductor-aligned capacitor 35 as A35 when being polarized and conducting and/or conducted inductively, such as the angular wheel 40 as A40 and/or induction actuator 41 itself, the angular wheel axle 50 as A50, the angular wheel coating 45 as A45 with induction actuator components, the caster bore for the angular wheel axel 38 as A38, and all potentially suitable and implied parts being solidary with the main central shaft 4 as A4, and the flanges 10 and 15 as A1015.

[00112] For example, the variation of the casters 35 as A35 polarity and angular position C, and the rotation A and the polarity of the drive shaft 5 in themselves along a full range of variable capacitive and inductive reactance with the interface of the displacement field 125 along and preferably within the tubular rail 115, with direct surface of contact and of displacement field 116 which limits the airgap.

[00113] A design with a closed tubular rail 115 may also be possible, and thus with having a capsule with live load inside the rail, for say between two terminals (pigs for pipelines, in-pipe inspection robots), and/or with having as well an a bonding field connected apparatus with an outside capsule from a closed rail 115 being capable of following the inside drive-shaft with a retaining electromagnetic field as a displacement device with the transportation system carrying the load.

[00114] In drawings 25 to 29, the polarization motorization field 125 of displacement occurs as patterns of magnetic flux direction along a tubular linearly axial and radial, with configuration of actuating stators ML for axial linear thrust in MLF induction force field potential and with configuration of actuating stators MYZ for axial and radial thrust in MYZFA and/or MYZFB induction force field potentials for the actuation of the induction actuators 41 both linearly in the L axis of linear inducting centerline and both Y and/or Z axis of radial inducting centerlines.

[00115] ML is the main axial linear inducting stator switcher of displacement and induction field differentiated direction of electromagnetic and superconducting potentialities.

[00116] MZY is the main axial radial and axial inducting stator switcher of displacement and induction field differentiating direction of electromagnetic and superconducting potentialities.

[00117] From drawing 28, MLF and MYZFA and MYZFB stators can be excited with a magnetic flux along solenoidal coils and/or permanent magnets that direct the inductive reactance axially for the MLF stators and both axially and radially for the MYZFA and MYZFB stators. The design and invention are not limited to such inductive reactance variation approach only. For instance, there could be an embodiment there in which apply superconducting magnets that can provide alternative inductive and capacitive reactance for the actuation of the induction actuators 41.

[00118] In drawing 29, the displacement field 125 embodiment is generated with ML and MYZ stators which interact by means of L, Y and Z crossings, and defined preferably but not limited to, junctions and relays of inductive and capacitive reactance. When combined, the crossings of L, Y and Z axis execute the function of directing a magnetic flux along junction relays for the actuators 41 poles YA and YB to be controlled along differentiating and differentiated directions of electromagnetic and superconducting potentialities in themselves determining the direction and speed of the drive shaft 5 with axial and radial Halbach arrays variations.

[00119] YA is the main radial and axial induction actuator 41 primary mover pole.

[00120] YB is the main radial and axial induction actuator 41 primary mover pole.

[00121] The interaction of the axial L and radial Y and Z stators and junction relays with permanent magnets and/or coils of the primary induction actuator 41 each having polarized endings that can interact both variably and produce a variable the AMF (alternative magnetic field) to generate a torque induction produced in the direction of YZ. The axis of orientation perpendicular to the 108 axis is YZ axis, both being about a radial axis 106 to the axis 105, being correlated to angular position C of the angular wheel 40.

[00122] The angular position of YZ variates correlatively with the main mechanism the aforementioned mechanism within drive shaft 5, and can actuate either linearly along attractive and repulsive forcefields of induction in axis L and/or angularly along said attractive and repulsive forcefields induction in radial and axial induction circumferential axis Z and Y all of which determines the direction and speed of the drive shaft 5 with interacting with the axial and radial Halbach array actuating variations.

[00123] Through drawings 30 to 36, the displacement field are herein described as follows:

- L is the main axis of the linear, said axial more properly, inducting centerline stator switcher of displacement and induction field differentiated direction of electromagnetic and superconducting potentialities.

- L axis can decline in both as LAI, LA2, LA3, and more, symmetrically from L as the main linear centerline, and in LB1, LB2, LB3, and more, as well symmetrically from L as the main axial centerline of all axial centerlines which directs inductive reactance thrust axially along the MLF stators; which produces axially and linearly a Halbach array which is interacting and inversing variably; and which the polarization from the magnetic flux frequency is axially driving the inducting actuators 41 along Y centerlines being alternated in the axial direction of L axis, and that can provide both axial and radial centerlines.

Y axis can decline in both as Yl, Y2, Y3, and more, starting from the first inductive MYZ stator perpendicularly to L as the main radial centerline which directs inductive reactance thrust axially along the MYZ stators. When the MYZ stators are interacting with angular wheels at a degree between plus 90 degrees and minus 90 degrees, the stators in ML are variably delayed at junction relays and thus preferably in the capacitive form.

Y is the main radial and axial inducting centerline switcher for the displacement and induction field differentiating direction of electromagnetic and superconducting potentialities of induction actuators 41.

[00124] The actuators 41 are comprised of primary moving poles YA and YB interacting about the MYZFA and/or MYZFB induction force field potential axial and radial patterns being led by the main driving interacting magnetic flux along junction relays for the actuators 41 poles YA and YB.

[00125] The embodiment of figures 30 to 36 is a simple and innovative approach being a turnkey solution with the variation of angular position C of angular wheels 40 and actuating magnetic fluxes and inductive force fields to generate transportation magnetic fields suited for helical traction and propulsion.

[00126] The angular position C of the angular wheels 40 can be variably following the YA and YB pattern of L, Y and Z crossings, and its control can be correlated preferably along the differentiating and differentiated directions of electromagnetic and superconducting potentialities in sync with the direction and speed occurring at force moment 107 with axial and radial Halbach arrays variations.

[00127] Inductive reactance is produced within a cylindrical Halbach actuator array, axially with MLF, and/or radially and axially with MYZ within Halbach arrays interacting and inversing variably the polarization along the L axis as crossing switches of junction relays actuated by the magnetic flux induced by the actuators 41 YA and YB.

[00128] The switching of Halbach arrays along MLF and MYZ interact directly with YA and YB of the LAB of the actuators 41, and can be the central transmission shaft itself A4, for example.

[00129] The LAB is the correlated axis of Halbach array angular drive of induction actuator 41 within axis 108 of angular wheel 40.

[00130] In figures 31, ZA is the alternative magnetic field drive orientation relative to axel 50 of main YA radial and axial orientation of induction actuator 41. And ZB is the alternative magnetic field drive orientation relative to axel 50 of main YB radial and axial orientation of induction actuator 41. When ZA and ZB of are parallel to Y and Z, they are also parallelly in aligned with YZ. The axis of orientation perpendicular to the LAB is thereby YZ. In such angular position, the YA and YB of actuators 41 are correlated to the angular position C in 9Z along Z centerline axis which corresponds to YZ1.

[00131] In figure 31, LABI is parallel to axis 105, being as well axis L, and YA and YB respective degrees ZA and ZB are being aligned respectively in 9A and 9B along Y centerline axis, with Z aligned with YZ.

[00132] In figures 32, LABI is angular to axis 105, with YA and YB respective degrees ZA and ZB being aligned respectively in 9A and 9B along Y1 and LAI centerline axis crossings and Y2 and LB1 axis crossings respectively and with Z1 aligned angularly with YZ1.

[00133] In figures 33, LABI to LAB4 are angular to axis 105, with their YA and YB respective degrees ZA and ZB being aligned respectively in 9A and 9B along Y1 to Y4 and LAI centerline axis crossings and Y2 to Y5 and LB1 axis crossings respectively and with Z1 to Z 4 aligned angularly with YZ1 to YZ4.

[00134] In figures 34, LABI to LAB4 are perpendicular to axis 105, with their YA and YB respective degrees ZA and ZB being aligned respectively in 9A and 9B along Y1 and both LAI and LB1 centerline axis crossings, and with Z1 to Z4 being perpendicular with YZ1 to YZ4 and parallel with L.

[00135] In figures 35, LABI to LAB4 are parallel to axis 105, with their YA and YB respective degrees ZA and ZB being aligned respectively in 9 A and 9B along Y1 to Y5 along and main L centerline axis crossings and with Z1 to Z4 being parallel with YZ1 to YZ4 and perpendicular with L.

[00136] In figures 36, LABI to LAB3 are perpendicular to axis 105, with their YA and YB respective degrees ZA and ZB being aligned respectively in 9A and 9B along Y1 to Y3, from LAI to LA5, and from LB1 to LB5 centerline axis crossings, and with Z2 and Z3 being perpendicular with YZ1 to YZ8 and parallel with L axis.

[00137] While illustrative and presently preferred embodiments of the invention have been described in detail hereinabove, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
