Description

UNIT RIO MECHANICAL MODULE FOR ELECTRIC VEHICLES DESCRIPTION D? THE INVENTION The present invention relates to an electric motor bicycle, and more particularly to a unitary self-contained direct drive mechanical module (or "unitary mechanical module") for electric bicycles or other vehicles. The invention also includes equipment for converting a standard bicycle into an electric bicycle by the use of a unitary mechanical module. For the purpose of background information, and now returning to the drawings, Figure 19 (a) illustrates a standard bicycle 100 ("or bicycle") which is a two-wheeled vehicle typically comprised of. a front steering wheel 102 and a rear wheel 104 that can be attached to the frame by quick disconnect units 105. The standard bicycle 100 includes a frame assembly 106 having a shaft 108 which articulates a front fork 110 for steering by the handlebar 109 by a cyclist of the bicycle 100. As illustrated in Figure 19 (b), the rear wheel 104 is hinged at the rear end of the frame 1,06 by a pair of rear supports (or "scraps") 112. A Seat tube 111 is carried by frame 106 adjacent to rear wheel 104 and a seat post 113 in which a saddle seat 115 is placed therein to accommodate a cyclist.

In the standard bicycle 100, a horizontally oriented journal (or crank stump) 117 is located under the seat tube 111 which supports a drive mechanism 120. "propelled" by a cyclist. The drive mechanism 120 generally comprises a crank 123 hinged on the crank stump 117 which includes a toothed chain 129 having a plurality of teeth together with the crank 123 located therein together with the pedals 125 rotatably articulated at each end 127 of the crank 123. Each wheel typically consists of a tire 114 mounted on a rigid rim 116, an axle 118, a wheel axle mechanism (or "wheel axle") 122 and spokes 124 connecting the rigid rim 116 to the wheel shaft 122 to form a shaft / axle assembly of the wheel 121. The wheel shaft 122 surrounds the shaft 118 and is free to encircle the shaft 118 through a support assembly 126 (not shown). The tire / rim assembly 128 is attached to the wheel shaft 122 through an assembly of the spokes 124 which are mounted in a woven pattern 130 to form a wheel / axle assembly of the wheel 140. This woven pattern 130 of Rays have relatively few variations with a large number of existing bicycle wheels that are common in the use of the same or similar to thirty-six or thirty-four lightning-weave pattern. A "chain" wheel tooth target 150 is mounted on the rear wheel 104, and is connected to the wheel tooth of the crank 129 by a chain 152 so that the application of power by the cyclist on the pedals 125 propels the bicycle 100. A derailer 154 is often replaced by the single objective wheel tooth 150 (or target wheel tooth), and may have a plurality of wheel teeth 156, 158, 160, 162, 164 and 166 (illustrated in the Figure 9) to provide variable gear for the cyclist's comfort when starting or climbing hills or for the cyclist's effectiveness. One of the characteristics of a bicycle is the ability of the wheel to be removed for repair, such as repairing a floor. As described above, the typical bicycle wheel is constructed of a tire / rim assembly connected to the wheel axle through a series of woven spokes. The axle of the wheel mounted on the wheel axle uses a support assembly. The axle / wheel axle assembly typically has rather imprecise manufacturing tolerances and as such provides a poor reference frame for the propulsion elements of the above systems. This occurs because bicycles are typically of high proportion, low cost, consumer products manufactured, so that the tolerances of the components are not as high as a high quality mechanism. Most bicycles sold in the world and in use are in the lowest or most inaccurate tolerance ranges. Also, when the wheel (or tire) is repaired and then replaced in the scraps of the frame, the shaft can become slightly raised with respect to the frame. As such, the tolerances by the mounted grooves of the wheel axle allow a wide latitude of assembly. Inaccurate manufacturing tolerances of the shaft and wheel axle / axle supports are typical of such low cost mechanisms. These large wheel tolerances and bicycle frame components present a significant problem in the design of reliable direct drive propulsion systems where several system components are mounted on different parts of the bicycle (for example, in the frame, in the shaft, etc.) If the various components of the propulsion system are mounted on the components of the bicycle, which have inaccurate tolerances in reference to one another, then the propulsion system suffers (or will suffer) from these same poor alignment tolerances with rough use. To avoid excessive use, reduced efficiency and reduced performance as a result of such imprecise tolerances, an effective propulsion system should ideally use a design that is independent of such imprecise tolerances in the bicycle axle / axle assembly as well as changing the relative tolerances of the table. It is this design concept that forms this invention. In the past, electric propulsion systems for bicycles have been implemented through a variety of methods that utilized electric motor power for any complement or replacement of the previous cyclist's drive mechanism in the propulsion of the bicycle. For example, these methods include friction roller drives, belt drives, gear drives, and chain drive. For example, friction drives typically involve the application of an electric motor or "drive source" to a wheel or "the target mechanism" through a roller mechanism. The roller can be attached directly to the drive source or through a clutch mechanism. The roller transfers the drive source energy through contact of the roller on the target wheel through friction between its respective surfaces. This type of drive system suffers from mechanical losses associated with the detachment between the roller mechanism and the target wheel as a result of reduced friction and the energy required to compress the rubber tire. The performance in humidity, rain, snow and mud is negligible at best.

By means of the additional example, electric bicycles have direct drive systems, such as belt drive, gear and chain, typically providing high power coupling efficiencies than friction roller drive systems.These systems however require a high degree of efficiency. mechanical integrity in the geometry of the drive components For example, there needs to be enough tension in the belt and chain of the belt drive systems and the chain and the proper alignment or gear engagement in the gear drive system The proper and accurate mechanical alignment must be rigidly maintained with the shock and repair many tires and wheels to extend the life of the unit.There have been a number of designs that can provide direct coupling between an engine or electric motors mounted externally to the wheel. the rear bicycle and the axle of the wheel. For example, an engine can be mounted either on the diagonal or the horizontal rear members (or "brackets") of the frame. A direct coupling in these cases can be carried out through a 90-degree bevel gear between the motor shaft and the axle-axle assembly of the wheel. In this case, external shocks will cause use of the gear. In addition, it is difficult to remove the rear wheel for repair. The drive can be done through a chain, which is better but still mechanically complex and subject to the same type of problems. It is also difficult to achieve the correct reduction ratios between the RPM of typical engines and that of the rear wheel, typically between 10: 1 and 25: 1. An engine can be mounted on the rear wheel and a very large "wheel tooth" of diameter almost as large as the diameter of the wheel can be operated. Such systems have been demonstrated but the strong upper part and the object to the relative dislocation of the elements have not been accepted because they are clumsy. Other direct drives have been reduced to practice with the motor mounted in the vicinity of the pedal crank. They can be coupled to the rear wheel by an engagement drive with suitable clutches inside the crank housing and therefore through the usual bicycle chain or through a separate long chain to a separate wheel tooth on the rear wheel. They can also be attached to the rear wheel through the long shafts and bevel gears. While some of these are usable and practical, they require a special style bicycle design that may be more expensive than desired. For designs in which a motor mounted externally to the rear wheel, an improvement is described in Patent Application No. 08/803, 067 entitled "Precision Direct Drive Mechanism for a Power Assit Apparatus for a Bicycle", by Mayer et al. . Presented on February 20, 1997. In this concept, an engine is mounted on a plate that is indexed separately to the axis of the rear wheel. The motor drives a pinion gear (or pinion wheel tooth) which is indexed separately to the axle of the rear wheel, which, through the meshed gears, a chain or belt drives a target gear (or wheel tooth) which is also attached to the shaft through a support or freewheel clutch arrangement. That is, the pinion-motor assembly with its frame mounted and the target gear (or wheel tooth) are separately indexed off the axle, with the target gear (wheel tooth) currently indexed from the wheel axle. Thus, these elements are precisely aligned in a benign environment with respect to each other, all being indexed from the presumably common and concentric points. However, even with this improved and more compact configuration, we have found in practice that for most bicycles, the tolerances of the support shaft and the tolerances of the wheel support shaft are highly variable with use and shock of the rough real world. In more detail, if the engagement between the pinion wheel tooth (or gear) and the target wheel tooth (or gear) occurs to a long lever arm of the shaft, the clearance of the bearings may change the engagement or alignment of the pinion gear / object, leading to the use of eventual gear, tooth breakage, or misalignment of such teeth. Additional concerns are the difficulties of achieving the alignment of shafts (such as the motor shafts, or the target wheel) and the fabricated tolerances of components over time and with rough normal usage. Another class of direct drive systems are based on the "wheel axle motors" which are designated on the axes of the front wheels or the rear wheels. This class of drives has its own considerations of cost and operating characteristics. None of the electric bicycle drive propulsion systems described above provide the important advantages of the inventive unit mechanical module for an electric bicycle propulsion system having a high degree of mechanical integrity in the alignment geometry of the drive components. still under shock and rough use. These advantages are achieved by the unique configuration of the unit mechanical module having drive components comprising a drive source (or an electric motor), a pinion drive coupling component (such as a chain wheel tooth, meshing). or pinion of the pulley or combination thereof), a coupled component of the target mechanism (or a chain wheel tooth, drive gear or belt wheel tooth), the actual mechanical coupling mechanism of the target or target wheel, and the drive wheel or target, a, which is usually the rear wheel. By using various ratios of the wheel tooth, the invention can achieve a wide range of gear ratios and therefore adaptability to a wide range of engines. Also, by the use of a freewheel clutch incorporated in the unitary mechanical module, the bicycle is completely free rolling without any drag in virtually no applied power. Additionally, when in production, the unitary mechanical module can be assembled and tested as an integral unit of operation, and then it is easily and simply attached to the bicycle frame. Specifically, the present invention achieves these advantages through the use of a unitary mechanical assembling module having a mounted frame assembly in which all propulsion elements are assembled and aligned with a wheel (or "drive") engaged, which is a disc-shaped assembly with a large center opening that allows the objective coupling to be placed around a wheel axis outside the diameter of the wheel axis.In the preferred embodiment, the objective coupling has a slot pattern which engages the Lightning pattern woven from a bicycle wheel to allow the objective coupling to be concentrically attached to the target wheel by the gear with the woven ray pattern by securing elements.The frame frame is attached to the target coupling by a support or like, even a freewheel clutch.The mounting plate has an opening (or "element") to r Elect an electric motor to enable a pinion or gear wheel tooth fixed on the motor to engage the wheel tooth and through a chain to the target wheel tooth (or gear) turn the wheel of the target bicycle on the power application Suitable for a cyclist using the propulsion controls on the bicycle. Thus, the present invention provides the advantages of having an independent self-contained separate (and self-aligning) self-contained unit mechanical module that overcomes misalignment problems between the drive source and the target by utilizing a common reference frame. The integrity of the alignment of the chain or mesh of the gear is therefore permanently to ensure even in the rough terrain and rough shock and use. This invention can thus be advantageously carried out using a chain drive, gear drive or belt drive system because one of its important advantages is its inherent cancellation of the usual causes of misalignment by the prior art devices. This has the additional advantage of being easily installed on almost any rear wheel of the bicycle by a single and mechanically described coupling. It works efficiently, essentially independent of the axle / wheel axle frame and assembly and the wheel / wheel axle tolerances. According to the invention, a unitary mechanical module for mounting a propulsion system on a bicycle comprises a frame frame having a motor and a target wheel tooth integrally mounted on the mounting frame. The objective wheel tooth defines a shaped disk member having a center opening to allow the driving wheel tooth to be positioned around an axis of the bicycle wheel. The driving wheel tooth is connected to a bicycle wheel through a clutch and the objective coupling makes it possible to mount the wheel tooth substantially concentrically to a wheel axle by gear with a wheel pattern of the bicycle by securing the wheel. elements. The mounting frame is rotatably attached to the target wheel tooth to allow for rotation "alignment" of the target wheel tooth around the wheel axis, and proper alignment with an electric motor. The mounting frame has an element for receiving an electric motor to enable a pinion wheel tooth attached to the motor to propel the target wheel tooth and rotate the wheel of the bicycle. In the method, the mounting box provides a single reference point for aligning the pinion wheel tooth with the target wheel tooth, ie, thereby allowing the unit mechanical module to operate on its own, for example in a bank , independent of the bicycle per se. In another embodiment of the invention, a propulsion system equipment is provided to convert a standard bicycle having a frame and front and rear wheel, with the rear wheel having a wheel axle and axle together with a wheel pattern in an electric bicycle. The equipment comprises a battery suitable for being fixed to the bicycle, an electric motor having a pinion wheel tooth (or gear) fixed thereto, with the electric motor suitable for being connected to the battery by a battery cable. A unitary member comprises a target wheel tooth, a gearbox assembly and reduction frame or chain mechanisms that precisely align with each other. The wheel tooth of the target coupling comprises a disk-shaped assembly having a center opening to allow the unitary member to be placed about the axis outside the wheel axis. The objective coupling has a pattern that attaches a rear wheel pattern to the target wheel tooth to allow the target wheel tooth to be concentrically bonded to the spokes by gear with the spoke pattern by securing the elements. The mounting frame is rotatably connected to the unitary member by a support or the like and has an opening for receiving the electric motor to allow the engagement of the target wheel tooth for the aligned rotation of the wheel in the application by the rider of controls. electric propulsion fixed to the bicycle. The freewheel clutch can be mounted either on the pinion-motor wheel tooth shank or on the wheel attachment mechanism. Thus, the mounting frame provides a single reference point for aligning the pinion wheel with the target wheel tooth. In still another embodiment of the invention, an electric bicycle comprises a frame having a cyclist's seat and the propulsion controls placed thereon. A leading driving wheel has an axle fixed to a front portion of said frame, together with a rear wheel that has an axle with a wheel pattern fixed to a rear portion of the frame.

The target coupling is fixed to the rear wheel to enable the target wheel tooth to be concentrically attached to the rear wheel by gear with the wheel by securing the elements. The mounting frame is secured to a fixed portion of the frame for transmitting torsional force and is attached to the unitary member through a support or the like and has an opening for receiving the electric motor to enable drive towards the engagement of the wheel tooth objective for the aligned rotation of the rear wheel in the application by the cyclist of the propulsion controls. Thus, the mounting frame provides a single reference point for aligning the pinion wheel tooth with the target wheel tooth. Preferably, according to the invention, a unitary mechanical module for mounting a propulsion system on a bicycle comprises an objective wheel tooth defining a shaped disk member having a center opening to allow the target coupling to be located around a wheel axle of the bicycle.

A mounting frame is rotatably attached to the target wheel tooth to allow rotation of the target wheel tooth about the wheel axis and has a suitable opening for receiving an electric motor to enable a driven wheel tooth attached to the motor to engage a second wheel tooth mounted by a second shaft located in the mounting frame. The second shaft of the wheel tooth is positioned to trigger the target coupling and rotate the wheel of the bicycle. In another preferred embodiment, a propulsion system kit is provided to convert a standard bicycle having a frame and rear and front wheels, with each having a wheel axle, axle and a spoke pattern, on a bicycle driven electric. A suitable battery for driving an electric motor is fixed to the bicycle, together with an electric motor having an actuator fixed thereto. The electric motor is suitable to be connected to the battery by means of a battery cable. A unitary mechanical module for mounting a propulsion system on a bicycle comprises a target wheel tooth defining a shaped disk member having a center opening to allow the target wheel tooth to be positioned around an axle of the wheel of a wheel. the bicycle with the target wheel tooth joining the bicycle wheel pattern to enable the wheel tooth to be substantially concentric attached to the wheel by gear with the pattern by securing the elements. A mounting frame is aligned and rotatably attached to the target wheel tooth to allow aligned rotation of the wheel tooth target around the wheel axis and has an opening to receive the electric motor that allows the drive to engage a second wheel tooth located to it. The second wheel tooth is mounted on a second shaft that engages the target wheel tooth to propel the target wheel tooth and rotate the wheel of the bicycle in the application by a cyclist of propulsion controls located in a bicycle frame. The mounting frame provides a single reference point by aligning the pinion wheel tooth with the target wheel tooth. In yet another preferred modality, an electric bicycle comprises a frame that has a seat of the cyclist and the propulsion controls placed and in it. The bicycle includes a driveable front wheel having an axle fixed to a front portion of the frame, and a rear wheel having an axle with a fixed pattern, to a rear portion of the frame. A propulsion system for the bicycle comprises a battery fixed to the bicycle, and an electric motor having an actuator fixed thereto, the electric motor suitable for being connected to the battery by a battery cable.

The mounting frame maintains a single reference point by aligning the pinion wheel tooth with the target wheel tooth. Preferably, the above embodiments having the second wheel tooth and the shank include a third wheel tooth concentrically mounted on top of the second shank, ~~ with the actuator that rolls the second wheel tooth which in turn rotates the third tooth of the wheel. wheel that is positioned to engage the target wheel tooth. In more detail, and by way of example, the target wheel tooth is preferably attached to the mounting frame by a support. In addition, a clutch way is fixed between the pinion wheel tooth and the motor. Further still, the objective coupling (or the target wheel tooth) may include a pattern of the groove arranged to join a woven beam pattern of the bicycle wheel, or simply joins with a wheel axle located on the wheel of the bicycle.

According to the invention, a disk-shaped member for an electric bicycle propulsion system preferably comprises a target wheel tooth comprising a disk-shaped assembly having a center opening to enable the target wheel-tooth member to be placed around a wheel axis, and the woven ray pattern that allows the tooth of the target wheel joining the woven ray pattern of a wheel to enable the wheel tooth to be concentrically attached to the wheel outside the diameter of the wheel wheel axis by the gear by securing the elements.

As pointed out in more detail in the following, the embodiments of this invention provide a »Significant number of advantages. For example, the key points of the invention include the establishment of a common reference or mounting frame and the structure that ensures precision alignment for the complete propulsion system under all conditions. This reference frame is formed by the disc or wheel tooth of the lens together with the cavity extension collar and the grooved surface. This disc provides a solid mounting joint with the wheel through the grooved surface that joins the axle of the wheel and spokes. The disc is kept concentric with the wheel axis, but an eccentrically large accuracy is not required. The gear of the wheel tooth is attached to the reference frame disc through a free-wheel clutch or directly attached to the reference frame disk. The motor mounting frame is attached to the reference frame disk through a bracket on the disc cavity extension collar. The motor is attached to the motor mounting frame, in such a way as to provide proper engagement of the actuators and the target wheel tooth, independent of the shaft tolerances and the wheel axle support. The driving wheel tooth (or gear) is attached directly to any motor, or through a form of roller clutch, depending on whether the gear (or tooth wheel) driver has a freewheel clutch. In this way, the pinion wheel tooth, the target wheel tooth and any intermediate gear are precisely aligned irrespective if they are interconnected by a chain, a gear, or a belt. The motor mounting frame is attached to the bicycle frame to prevent rotation of the mounting frame, that is, to transmit torque force from the propulsion to the bicycle. The invention maintains the entire propulsion system within the same frame of reference, thereby inhibiting the propulsion system tolerances within the propulsion system. These tolerances are determined by the manufacturing tolerances of the propulsion system components as designed independent of the vehicle manufacturing tolerances. This allows the propulsion system to be applied to any vehicle, while maintaining the integrity and operation of the propulsion system. The invention itself, together with the additional objects and attendant advantages, will be better understood by reference to the following detailed description taken in conjunction with the accompanying drawings.

Figure 19 (a) is a side elevational view of a standard bicycle, and Figure 19 (b) is an enlarged view of the opposite side of the rear wheel of Figure 19 (a). Referring now to Figures 1-3, an important aspect of the unitary motor module 200 (or "unit propulsion module") concerning the proportions of a reference frame for aligning a pinion wheel tooth to a wheel tooth objective. This is achieved by the use of a "mounting box" 204 of the unitary motor module 200 to accurately align a pinion wheel tooth 242 of an electric motor 230 to the wheel / wheel axle assembly 140. (shown in Figures 3 and 19). As all the drives and objective elements of the unit mechanical module are mounted to the mounting frame 204, a single integral and the independent reference point ensure their proper alignment. The attachment of the mounting frame 204 to the spoke / wheel axle assembly 140 (and to the bicycle frame) allows a stable reference frame, since the wheel / axle assembly of the wheel 140 is attached directly to the tire / rim assembly 128 of the wheel 104 (what is the objective drive mechanism of the unit motor module 200). As described hereafter, this reference frame eliminates imprecise or varying tolerances of the wheel / axle assembly of the wheel 140 and the tire / rim assembly 128 and the axle 118 and the frame assembly 106, so that it provides rigid alignment of the drive and the objective elements of the unitary motor module 200 even with the accompanying shock and the holder of use in such drive systems. Turning now to Figure 1, in one of the preferred embodiments of the invention, the mounting frame 204 is connected to a motor having a pinion wheel tooth 242 mounted thereto which are interconnected by a chain 211 to a tooth of target wheel 202 with a target coupling 203 having a pattern 205 (shown in Figure 5 (b)) that joins the woven ray pattern 130 of the bicycle wheel (shown in Figure 19). An inactive wheel tooth (or gear or pulley or "idle") 228 can be used to provide tension between a chain 211 to secure the gear between the pinion wheel tooth 242 and the target wheel tooth 202. The inactive 288 also it can be used to allow the chain 211 to engage more teeth of the pinion wheel tooth 242 and thus allow closer spacing between the pinion wheel tooth 242 and the target wheel tooth. The mounting frame 204, when attached directly to the target wheel tooth 202 through a support 206, such as a ring bracket, allows the reference frame of the target wheel tooth 202 to rotate freely within acceptable tolerances while maintaining its mechanical attachment to the mounting frame 204. In addition, the mounting frame 204 includes an opening of motor 224 shown in Figures 2 and 3 (or other mechanical element for attachment) for a motor 230 to be located thereto. Figure 2 illustrates the position of the engine 230 having a motor shaft 244 that meshes a planetary gear 246 suitable for reduction of the gear, such as RPM reduction from 5: 1 or 7: 1. By the use of this important configuration, the planetary gear reduction system between the motor shaft 244 and pinion wheel tooth 242 allows the user to select the preferred ratio of the overall RPM between the motor and the bicycle wheel. which can be adjusted over a wide range of high values. The planetary gear 246 in turn engages the pinion wheel tooth 242, which is interconnected by a chain to the target wheel tooth. This simple configuration will be the lowest cost of certain applications. The ratio of the overall reduction between the engine RPM 230 and the RPM of the bicycle wheel 104 is easily adjusted by the ratio of diameters or number of teeth between the pinion wheel tooth 242 and the target wheel tooth 202. A fast disconnect 500 for the -motor 230 is provided to provide a strip 245 on the motor shaft 244 which is attached to the inlet of the planetary gear system 246. Of course, in a simpler configuration the gear reduction is not needed yet. planetary. For example, the motor 230 can be connected directly to the pinion wheel tooth and the ratio of the overall RPM between the motor 203 and the drive wheel 104 (not shown) is smaller. In this case, a lower RPM motor is necessary. As further illustrated in Figure 3, the mounting frame 204 receives the motor 230 having its motor shaft 244 perpendicular to the mounting frame 204. Through the mechanism as illustrated in Figure 1, the motor 230 is suitable to provide power to the pinion wheel tooth 242. The target wheel tooth 202 is attached to an extension collar (or rotating tube) 207 or the like, which is interconnected to a target coupling 203 which engages the spokes 124 of the wheel bicycle 104 around the axis of the wheel 122 but mounts to the spokes 124 outside the axis of the wheel 122. The objective coupling 203 has the same wheel tooth pattern 205 of the bicycle wheel 104 and is fixed thereto as illustrated additionally in Figure 8 (b). The internal diameter of this complete assembly becomes large enough to fit over virtually all types of the wheel axle 122. The coupling secures the spokes and typically propagates the torsional force of spokes 16 or 18 to its strongest point. This objective coupling 203 is rigidly connected to (or part of) the rotating tube 207 that can be rotated with respect to the mounting frame 204 due to the ring support 206. Thus, as described, the invention provides a common reference point for the various components of the. direct drive system that allows to control the tolerances within the propulsion drive system as well as isolated from the tolerances of bicycle components. Simply by way of example, the target wheel tooth 202 and the target coupling 203 (or "interlocked coupling") can be constructed of any designed plastic or aluminum that can be molded, and the mounting frame 204 is preferably aluminum, both by light weight and relatively high thermal conductivity for the purpose of dissipating engine heat. As noted in the above, target wheel tooth 202, which is preferably driven by a chain 211 of the tooth, pinion wheel 242, is mounted through a freewheel clutch 277 proximate the rotary tube 207. The freewheel clutch allows the wheel to rotate freely without entrainment of the electric motor 230, when the electric motor is not being driven. This wheel-free clutch 277 significantly reduces the drag of the wheel, a discernible effect to the cyclist of the bicycle, and improves the range of the bicycle. The wheel free clutch 277 can be implemented as a roller clutch or "free wheel" in the pinion wheel tooth gear or as a free wheel clutch in the target wheel tooth. In this way, when the target wheel tooth rolls faster than the rear wheel, it engages and drives the wheel. When sliding with the engine off, the free wheel allows the rear wheel to rotate with the target wheel tooth 202 disengaged. An appropriate "freewheel" or "one-way roller" clutches that can be incorporated into the unitary motor module 200 are made from Dicta Corp. or Lida Machinery Co. , Ltd. of Tao Yuan, Taiwan, and is a freewheel that employs ratchets in the clutch. It is located on the target wheel tooth that drives the rear wheel. It is incorporated in the gear or wheel tooth and is concentric with the axis of the wheel as part of the mechanism. Another suitable unit is a roller clutch made by Torrington, Inc. of Connecticut that can be incorporated into the intermediate shank in which are two wheel teeth mounted in the two stages of gear reduction configuration. As described hereinafter, there are several methods for implementing a clutch feature in one way for the propulsion system, for example, one possible way would be to put a roller clutch between the motor and the pinion gear. An alternate mechanization would be to put a clutch of the free wheel between the wheel and the target wheel tooth or gear. If the clutch of the free wheel is located between the wheel and the drive gear, then the free wheel should be attached to the cavity extension collar of the reference frame disc already described. On the other hand, if a clutch is carried out in a manner between the motor and the pinion gear, the driven gear should be directly and firmly attached to the disk and the cavity extension collar. As illustrated, a ring bracket 206 allows the mounting frame to rotate around a rotating tube. The rotating tube 207 is rigidly attached to the target coupling 203 (or beam coupling or lens coupling, which as illustrated is a shaped disk member that is circular with the tube 207 (or a cavity collar) in the center. The support 206 connects, and interconnects the target wheel tooth 202 having the cavity collar 207 in a centrally located opening 208 of the target wheel tooth 202 and an opening 210 of the mounting frame 204, which are concentric to each other. The objective coupling 203 which drives the bicycle wheel is a shaped disk member having the central opening 208 and an external and internal surface 212, 214. In this embodiment, the target wheel tooth 202 includes a plurality of teeth of chain 216 suitable for engaging the chain 211 in this embodiment.The cavity collar 207 allows clearance of the wheel shaft 104. The freewheel clutch (or "freewheel") can also be mounted as described in the above or in any target wheel coupling-tooth mechanism or the output shaft of the planetary gears 246. The target wheel tooth 202 is mounted on the rotating tube 207 by the freewheel ("freewheel"). ) or in a manner the clutch 277. The freewheel 277 can be mounted on the motor shaft 244 between the pinion wheel tooth 242 and the motor shaft 244. As illustrated, when the motor 230 is off and the shaft is stationary, the pinion wheel tooth 242 can rotate along with the chain 211. The rotary tube 207 is precisely mounted to the mounting frame 204 by a ring bracket 206 or concentric with the rear axle. The mounting frame 204 is mounted to the bicycle frame 106 by elements ensuring adequate 235, as shown in Figures 14, 15. For example, as can be understood from Figures 14 and 15, the quick disconnect (or the "quick disconnect clamp") can be attached to the mounting frame 204 to the bicycle frame 106 ( by any diagonal or horizontal rear support 112) instead of securing the elements 235. In this way, the torsional force of the propulsion system is transmitted to the rear wheels which of course, eliminate any rotation between the mounting frame 204 and the bicycle frame 106. When the engine 230 is off, the target wheel tooth 202 is stationary and the bicycle wheels coupled to the tube can rotate due to the action of the freewheel 277. When the engine 230 is on, ie , the target wheel tooth 202 is rotating faster than the bicycle wheel engaged, the free wheel 277 engages and "the target wheel tooth 202 drives the bicycle wheel couplings coupled to the tub As described in Figures 1, 3, the unit motor module 200 is completely independent of the bicycle per se as it can be operated by itself, for example, in a bank. The mounting frame provides and maintains rigid alignment of the complete propulsion module independent of the tolerances of the axle shaft of the bicycle wheel. The unitary mechanical module, when attached to the spokes, may even be off a little from the center off with respect to the axis with remarkably small effect. In addition, as illustrated in Figures 14 and 15, the unit motor module 200 can be attached to the frame by the quick disconnect 234 to ensure easy repair or replacement of a tire or the module itself. Returning now to Figures 4 (a) and (b), the invention can be practiced when forming the target coupling 203 and the target wheel tooth 202 in an integral unit. In addition, as illustrated in Figure (b), a belt 278, such as a "V" belt 278 can be used in place of a chain interconnecting the pinion wheel tooth 242 and the target wheel tooth 202. As shown in FIG. illustrated, a "V" slot 284 is formed in both of the pinion wheel teeth 242 and the target wheel tooth 202 (and the inactive wheel tooth 288) to receive the "V" belt. Similarly, the target wheel tooth 202 defines a similar surface groove 286 for receiving a "V" belt 278 or the like. Other forms of belt configurations can be easily used by modifying the pinion wheel tooth 242 and the target wheel tooth 204 to receive such belts 278. Simply by means of the illustration, Figures 5 (a) and 5 (b) show another embodiment of the unit motor module 200 suitable for using meshed gears (with the gear of the pinion in the ed line) when it was observed "outside" of the bicycle 100. The meshed gears, in contrast to a chain and wheel tooth, have the advantage of being very compact and can work very well with this rigid alignment concept of the mounting frame 204. In this embodiment, the pinion wheel tooth 242 (shown in a ed line) or the pinion pulley must be located closer radially towards the t gap so that the appropriate gear is maintained between a gear of the pinion and the target wheel tooth. Also, the motor rotates in the opposite direction to the drive for the chain drive. As described, the mounting frame 204 and the target wheel tooth 202, which is aligned together with a freewheel clutch 277 located therebetween. The mounting frame 204 is mounted to the target wheel tooth 202, albeit an opening 210 in the mounting frame 204, by means of a connection to a tube cavity extension 207 or the collar 207 ("tube 207") of the tooth of the tooth. target wheel 202 that is mounted to bicycle wheel 104 as described in the following. A projection 209 can be formed on the mounting plate 204 to secure the mounting plate 204 by means of a clamp or similar to the frame assembly (not shown). Returning to Figure 5 (b), the inner surface 214 (not shown) on the other side of the target wheel tooth 202 includes an annular region 218 located generally concentric on the target wheel tooth that opens 208. The annular region 218 includes a plurality of slots 220 that adjust the beam pattern of a standard bicycle wheel (e.g., such as the common 36-spoke or 34-spoke configuration, the middle at each wheel end 122). A plurality of drilled tapered holes 222 are spaced around the annular region 218 which serves the purpose of receiving screws (not shown) for securing the target coupling 203 to the wheel spokes 124. Alternatively, the keyways (not shown) may have gaps. (not shown) can take place from the gaps joining the plate (not shown, but illustrated in Figures 6 ((b)). The mounting frame 204 defines a second opening 224 for receiving an electric motor (not shown). As illustrated with ed lines, the pinion wheel tooth 242 (SI) is positioned to engage the target wheel tooth 202. An enlarged view of the annular target coupling pattern suitable for engaging the spokes 124 of a spoke 33, Cross wheel of a bicycle wheel is shown in Figure 5 (c) As illustrated, the target coupling 203 includes cross slots 224 to form spokes 124 of the bicycle wheel e provides a firm mechanical coupling of the target 203 link to the bicycle wheel (not shown). While Figures 5 (a) and 5 (b) illustrate a tangled gear drive system, a chain drive system as described above involves only moving the pinion wheel tooth of the wheel tooth 202 and using the teeth better than the gears in the target wheel tooth 202. As described above, the motor in a chain drive would rotate in the opposite direction as a meshing drive gear to impart the same rotary direction to the bicycle wheel. As illustrated in Figure 6 (a), the unit motor module 200 is shown as having an electric motor (or motor) 230 when it would appear to be "outside" of the bicycle wheel if it is attached to the wheel (not shown). An electric motor 230 suitable for use with this invention is a motor brush having an operating speed R.P.M. of about 3000 R.P.M. at approximately 4000 R.P.M. together with the integral control electronics. Brush motors of a wide variety, can be used. Other motors with a wide range of RPM operation can be used with several reduction mechanisms taught in it. The motor 230 has an electrical 232 cable suitable for plugging into a connector module 231 for interconnection to a battery. As illustrated in the above, the target wheel tooth 202 is mounted in the mounting frame 204 in the second opening 224 provided therein. The large diameter of the opening 210 in the mounting frame 204 is suitable for slipping on top of the wheel / wheel axle assembly. The motor 230 can be quickly attached to the mounting frame 204 by quick release labels 234, and can be quickly removed by the rotation of the labels 234 or other similar quick disconnect insurers. As illustrated, the pinion wheel tooth 242 is coupled by the chain 211 to the target wheel tooth 202. In this way, the motor 230 can be quickly removed or simply replaced by the release of the labels 234 and disconnecting the cable. 232 of the connector module 231 inside the motor 230. Returning now to FIG. 6 (b), the target wheel tooth 202 is mounted on the opposite side of the mounting side 204 of the motor side. Since this is an integral "unit mechanical module", the pinion wheel tooth 242 ("SI") and the target wheel tooth 204 (or "S4") remain perfectly meshed or aligned with each other, whether or not the module it is exactly concentrically attached to the bicycle wheel 104 and independent of any loose tolerance and changing tolerances of the axle of the wheel or supports. In addition, in cases where the bicycle wheel deforms or is otherwise in less than a planar configuration, the alignment of the chain between the pinion wheel tooth 242 and the target wheel tooth is accurately maintained . Figure 6 (b) also illustrates the use of the ring assembly 236 to secure the target coupling 203 to the wheel of the wheel hub 122. The inner surface 214 of the other side of the target link 203 includes an annular region 218 which is concentric with the objective wheel tooth opening 208. The annular region has cross slots 220 that adjust the lightning pattern 130 of a standard bicycle wheel (not shown). The recesses 222 are located in the annular region 218. The cross slots 220 adjust, the ray pattern 130 of the bicycle wheel, such as the rear wheel of Figure 19. In Figure 7, the target module 204 is shown in combination with the target wheel tooth 202 having the target coupling 203 (shown in shaded lines) engaging a beam of thirty six beam, three cross wheel patterns of a bicycle wheel. A suitable material for the construction of the target coupling 203 would be Al 6061 having a black coating or the like, or it could be made of a plastic together with the molded metal strung inserts. For precisely the integration of a woven pattern 130 of a spoke wheel, the target coupling 203 provides a rugged construction suitable for receiving the imposed torsional force loads on the target wheel tooth 202. Turning now to Figure 8, the module of unit motor 200, with a motor 230 and the pinion wheel tooth 242 using the chain 211 drives the target wheel tooth 202, is shown in an "outside" side view of the bicycle wheel 104. The bicycle wheel 104 includes an axle 118, a wheel axle 122, a plurality of spokes 124 positioned around the axle 118 (as further illustrated in Figure 16 (a) (b) (c)), and connecting the pneumatic / rim assembly 124. The mounting frame 204 and the target wheel tooth 202 are mounted around the shaft 118 although the opening target wheel tooth 208 and the plate aperture 210 -respectively on the target wheel tooth 202 and the mounting frame 204 . As illustrated in the foregoing, the unit motor module 200 includes a plurality of quick-release mounts, such as the labels 234, the motor 230 can be rapidly detached from the mounting frame. When re-engaging, the exact gear alignment is automatically established. This aspect provides significant advantages, when it is useful for easy repairs (replacement) and to convert the bicycle from one side to another between conventional electrical configurations. Also, a clutch roller manner 240 may be concentric with the target wheel tooth 202 and the bracket 206 or may be attached to a pinion wheel tooth 242 in the motor. As it is apparent, this is a module of the complete propulsion or "equipment" to convert a bicycle into an electric bicycle. That is, if voltage is applied to the motor, the motor can drive the pinion wheel tooth which in turn can handle the larger 202 target wheel tooth and functions as a unit independent module. In addition, this unit mechanical module 200 can be attached to the outside diameter of the wheel of the wheel axle 122. The mounting frame 204 is easily rotated about the wheel axis for any position to join the frame 106 which does not interfere with the support of the bicycle frame 112. As illustrated from the "inside" perspective in the Figure 9, the unit motor module 200 with the motor 230 and the pinion wheel tooth 242, is mounted to the bicycle wheel 104, with the spokes 124 and the wheel shaft 122 by a mounting ring 236. Mainly for the illustration, the "interior shows a derailed gear group 156 and has a plurality of teeth 156, 158, -160, 162, 164, and 166 suitable for manual gear adjustment." As described above, Figure 9 shows the coupling of the target coupling 203 (or the target wheel tooth 202) connected or meshed with the bicycle wheel 104 in the following manner: the mounting ring 236 formed by two semi-circular pieces 238,239 the affluence adjusted against the wheel tooth 202 and assures it to be positioned to receive the spokes 124. A plurality of screws 249 (or pins where the holes 222 are replaced with keyways) or the like, extend through the wheel that the spokes 124 then secure to the tooth target wheel 202 as a unit to the bicycle wheel 104. As a result the target wheel tooth 202 tightly and precisely joins the wheel / wheel axle assembly of the wheel 104. The target wheel tooth 202 through the virtue of the grooves maintained precisely to the wheel 104, maintaining concentricity with the wheel / wheel axle assembly, although perfect concentricity is not required. In this way, the target wheel tooth 202 can be rigidly mounted to the spokes 124 of a bicycle wheel 104. The mounting ring 236 includes a plurality of recesses 270 that joins the recesses 222 of the annular region 218 of the tooth of the wheel. target wheel 202, as shown in Figure 5. It is important to recognize that the unit mechanical module 200 automatically focuses on the reasonable and practical tolerances on the axis of the bicycle 100 to a fairly close tolerance. Perfect centering is not required for drive gear alignment - perfect pinion. It is important to note that the opening of plate 210 in the mounting frame is much larger than the wheel axis and diameter of the wheel axis. Thus, the entire unit can be rotated about the axis for an adequate angular position with respect to the members of the bicycle frame 106. The mounting frame 204 is then connected to the frame by a strap or plug 235, as shown in the Figure 14 or a quick disconnect clamp such as a clamp "C" (not shown). This is necessary to maintain the position of the unit with respect to frame 106 and to transfer the torsional force to the frame. When this connection can be the quick disconnect clamp, it facilitates the rapid disconnection of the module 200 from the frame 106 and the repair of the rim / fast tire. Turning now to Figures 10 (a), 10 (b) and 11, another preferred embodiment of the unit mechanical module of the present invention is illustrated. In this embodiment, the unit mechanical module includes an objective wheel tooth 202 ("S4") defining a shaped disk member having a center opening 210 to allow the target wheel tooth 202 to be placed to be placed on the axis of the wheel. 118 wheel of the bicycle. As in the above, the target wheel tooth 202 is joined with a bicycle wheel 104 to enable the target wheel tooth 202 to be substantially concentric with the gear wheel, the woven beam pattern 130 by the target coupling 203 and the insured items as described above. The mounting frame 204 is aligned with and rotatably attached to the target wheel tooth 202 to allow rotation of the target wheel tooth 202 ("S4") around the wheel axis 118. The mounting frame 204 has an opening 224 for receiving an electric motor 230 for enabling a pinion wheel tooth 242 ("SI") fixed by the motor shaft 244 of the motor 230 to engage a second wheel tooth 250 ("S2") by the chain 211. The mounting frame 204 includes the projection 209 which enables the mounting frame 204 to be secured to the frame. The second wheel tooth S2 is mounted by a second shaft 252 located in the mounting frame 204, is aligned with the pinion wheel tooth 242. The third wheel tooth 264 ("S3") is also mounted on the same second shank 252 as the wheel tooth S2, and is aligned with the target wheel tooth 202. The third wheel tooth S3 is positioned to engage the target wheel tooth 202, such as by the chain 276, and the rotatable target wheel tooth 202 thereby rotates the bicycle wheel 104. In this "2-chain" mode there are two teeth, S2 and S3 mounted on an intermediate shaft. The motor drive pinion wheel tooth 242 (SI) through the first chain 211. The wheel tooth S2 which is normally larger than SI, in turn drives S3 and the final wheel 202 target tooth (S4) ) by a second chain 276. While the teeth SI, S2 are on one side of the mounting frame 204, and the wheel teeth S3 and S4 are illustrated on the other side of the mounting frame, the tooth pair SI, S2, S3 and S4 may be in several positions with respect to the mounting frame 204, for example, SI and S2 may be on the same side of the mounting frame 204 with S3 and S4. By using the two drive chains, the overall gear ratio can easily be adjusted by placing the number of teeth in SI, S2 (or the other wheel teeth). Also, in a similar manner, two or more belt drive systems can be used. Consequently, this can provide great flexibility and reduced size as different engines that have different costs, RPM, etc., can be easily adapted as the power sources. As described, it is apparent that this configuration is elegant and very compact. Also, in this case the free wheel 227 can also be mounted, concentric with the axis between the target wheel tooth 202 and coupling 203 in this case, or, for example, in the intermediate shaft between S-1 and S-2. In another embodiment of the invention, as illustrated in Figure 12, the mounting frame 204 may include a second opening 270 additionally (not shown) suitable for receiving a second electric motor 272 having a second pinion wheel tooth 274. The second pinion wheel tooth 274 can be connected to the pinion wheel tooth 242 in a manner that the target wheel tooth 202 is driven by both electric motors 230, 272. For example, the pinion wheel tooth 242 and the second pinion wheel tooth 274 are connectable and aligned together by a chain 276 to provide rotational power to the target wheel tooth. Also, one of the motors 230 may include in one manner the roller clutch 240 and the other electric motor 272 may include a roller clutch. In this way, one motor can be closed off while the other motor is operating to mount the level, however, for the degree of inclination the second motor can be turned on to effectively bend the available power to the target wheel tooth and the wheel. the bike. As understood, one or more independent integral propulsion modules can be mounted to a bicycle and optimum torsional strength and efficiency at relatively low RPM can be provided. In another embodiment of the invention shown in Figures 13, the motor 230 is mounted in the mounting frame 204 in a parallel (or horizontal) position for the main axis of the mounting frame 204. By the use of a pair of bevel gears 290, 292, the motor pulse 230 is supplied to the target wheel tooth. By the use of this configuration, a cylindrical motor 230 whose axis is parallel to the plane of the mounting frame can be used. The bevel gear 290, 292 which transmits rotation of a shaft parallel to the mounting frame to a shaft perpendicular to the plate, can work reliably with shock and vibration due to the rigid "unitary" assembly. All the other propulsion elements are the same. This provides additional ability to adapt to longer cylindrical motors instead of pancake designs. In this way, the width of the engine projection can be minimized and another engine having an extended cylindrical shape can be used without having the engine projection a substantial horizontal distance. Another embodiment of the invention is shown in Figure 14 which illustrates an equipment 299 for converting a standard bicycle (shown in shaded lines) to an electric bicycle that easily connects and is disconnected from any bicycle. It allows the simple fall of the rear wheel by the wheel and repair of the tire.

By using this equipment, the unitary mechanical module can be easily mounted or attached to the outer diameter ("O.D".) Of a bicycle wheel wheel axle, virtually adjusting any bicycle and quickly transforming it into a high-performance electric bicycle. In more detail, the propulsion system equipment is provided to convert a standard bicycle having a frame 106 and the front wheel 102 and the rear wheel 104, with the rear wheel 104 having a shaft 118 and wheel spindle 122 together with a wheel pattern (or woven pattern) 130 on an electric bicycle. The equipment 299 comprises a battery 300 suitable for being fixed to the bicycle 100, an electric motor 230 having a pinion wheel tooth gear 242 fixed thereto, with the electric motor 230. suitable to be connected to the battery 300 by a battery cable 232. The 328 propulsion controls are attached to the .109 handlebar by the speed control. These components together with the above unitary member 200, and all the components described in the foregoing comprise the "equipment," which can convert any standard bicycle into a high-performance electric bicycle. Also, as illustrated in Figure 14 (and Figures 6 (a), (b), and Figure 8 above), the equipment 299 provides the components of the unitary motor module 200, which includes the electric motor 230 which is joins the mounting frame 204. The connection of the motor 230 allows for the pinion gear 242 to entangle itself with the target wheel tooth 202 fixed to the wheel of any standard bicycle by the target coupling 203, independent of the axle support and the support tolerances of the wheel axle. A warning frame clamp 235 is attached to the projection 209 of the motor mounting frame 204, to prevent the motor 230 and the mounting frame 204 from rotating on the frame assembly 106 and thus provides a point of the stable mount for the unit mechanical module. Alternatively, the clamp 235 can be replaced with the previously suggested quick disconnecting element (such as the quick disconnect 234 shown in Figures 18 (a), (b) and (c)) so that the unitary wheel / wheel module wheel can be slid quickly by the tire / wheel component. This quick disconnect is similar to the quick disconnect fitted with the bicycle wheel clamps to the scraps in the bicycle frame. • As illustrated in the foregoing, the unit motor module 200 includes a plurality of fast discharge settings, such as the labels 234, the motor 230 can be quickly highlighted from the mounting frame. When the exact gear alignment is set automatically. These features provide significant advantages, when both are useful for easy repairs (replacement) and for converting the bicycle backrest and establishing between conventional and electrical configurations. Also, one way of roller clutch 240 may be concentric with the target wheel tooth 202 and the bracket 206 or may be attached to a pinion wheel tooth 242 in the motor. As it is apparent, this is a complete propulsion module or "equipment" to convert a bicycle into an electric bicycle. That is, if voltage is applied to the motor, the motor can drive the pinion wheel tooth, which in turn can drive the larger target wheel tooth 202, and function as a unit self-contained module. In addition, this unitary mechanical module 200 may be attached to the outer diameter of the wheel axis of the bicycle 122. The mounting frame 204 is easily rolled around the axis of the wheel by any position to attach to the frame 106 that does not interfere with the bicycle frame support 112. In another embodiment of the invention illustrated in the Figure 15, an electric bicycle 400 comprises a frame 106 having a cyclist's seat 115 and the propulsion controls 328 positioned therein. A steerable front wheel 102 by handlebar 109 has an axle 118 fixed to a front portion of frame 106, together with a rear wheel 104 having an axle with a wheel pattern fixed to a rear portion of the frame. A propulsion system 400 comprises a battery 300 attached to the bicycle 400, and an electric motor 230 having a pinion wheel tooth 242 fixed thereto of the electric motor 230 suitable for being connected to the battery 300 by a battery cable 232. These components, together with the unit mechanical module, described in the foregoing, comprise the electric bicycle 400 according to the present invention.

As illustrated in Figures 16 (a), (b) and (c) the practice of the invention of Figure 15 (and of Figures 1-14) is not limited to an objective coupling 203 having a lightning pattern. "interlaced", but may use a variety of modalities of a target coupling 203 to transfer rotary power to the rear wheel and may provide an independent self-alignment system. Turning now to Figures 16 (a), (b) and (c), with similar numerals illustrating similar elements, the axis of the wheel 122 rotates around a support assembly 126. The axis of the wheel 122 has an "extended" flange 514 having a sufficient annular extension to form a plurality of openings 516 around the flange 514 for receiving the securing elements 518, such as keyways, bolts, screws or the like, placed in a matched plurality of openings 522 forward or inside the target wheel tooth 202. In this manner, the target wheel tooth 202 in combination with the elements 518 the target coupling 203. In this embodiment, the free rotating clutch 277 is positioned on the pinion wheel tooth 242 Turning now to Figure 16 (b), the freewheel clutch is positioned between the target wheel tooth 202 and the wheel axle 122. The axle of the wheel 122 has extended flanges 53, 534 that are n close or adjacent to the tooth target wheel 202 and the flange of the wheel shaft 514 respectively. The elements 518 securing, such as keyways, bolts, screws or the like, placed in a matched plurality of openings 522 in or within the target wheel tooth 202 attached with a plurality of openings 536 in the flange of the free wheel 532. The securing elements 540, such as keyways, bolts, screws or the like, placed in a matched plurality of openings 538 in or within the flange of the free wheel 534 attached with a plurality of openings 522 in the target wheel tooth. In this way, the combination of the target wheel tooth 202, the flanges 532,534 in the wheel free clutch 277 and the secured elements 518 and 540 form the target coupling 203. Figure 16 (c) shows a double ended wheel axle 550 having a pair of free-wheel clutches 277 on the outside of each extended wheel axle flange 514 of the flange 122 with the target wheel tooth 202 located in an annular configuration on the clutch of the free wheel 277. The clutches of freewheel 277 are fixed to the shaft by the use of a threading 552 placed therein. In this way, the combination of the target wheel tooth, the freewheel clutch 277 and the threading of the shaft 552 forms the target coupling 203.

Turning now to Figure 17, a disengage motor bracket 500 that can be used with the present invention using any chain, or belt drive as illustrated. For example, the "quick disconnect" feature for motor 230 will be used in various applications such as for folded bicycles, or in areas where 230 motor safety may be required. The "quick disconnect" feature can be used where the ends of the motor shaft 502 have a strip that slides in and out of the shaft in which a wheel tooth or wheel teeth are mounted. As illustrated, the motor shaft comprises an outer strip 504 which engages a shaft 506 with an inner strip 508 which is supported by two supports 510, 512 spaced apart in the mounting frame 204. The motor housing includes fast-release labels 234, or the like that can be moved quickly, by which they allow the motor shaft 502 to be removed or inserted within the inner strip of shaft 508. Returning now to FIGS. 18 (a), (b) and (c) a Quick disconnect motor holder 600 can be used with the present invention using a gear drive. Whereby e.1 gear for gear engagement between the pinion wheel tooth 242 and the target wheel tooth 202, by mainly rotating the labels 234 as illustrated in Figures 18 (a), (b) and (c) allowed the motor to be removed from an open to closed position, respectively. As it is apparent, by the mounting frame 204 including a shaft suitable for engaging and disengaging a motor shaft 244 from a power to a power position without power in any gear or disengagement of the motor 230 from the mounting frame, the motor 230 can Remove quickly for storage and care when necessary. Primarily by means of the illustration, the following examples establish the typical design parameters to achieve the predetermined operation of the torsional force and efficiency. EXAMPLE 1 The present unitary mechanical module can provide optimum cycling of the torque and efficiency by reducing the RPMs of a high RPM motor to a relatively low number of revolutions per minute ("RPM"). to push the bicycle at a predetermined speed. For example, for a given pinion of modest diameter of 1"(what is necessary to keep the unitary reasonably small overall mechanical module), the reduction of the overall speed of the engine RPM can be determined by the selection of the target wheel tooth. a diameter of the given target wheel tooth of 7"and the diameter of the pinion of 1", the resulting reduction ratio is 7: 1. If a gear of the pinion is used, it must be of this order of diameter to allow for less than several teeth engage driven gear for low noise, efficiency and tension At 10 miles per hour ("MPH") for a 26"wheel bicycle, the wheel RPM and driven gear is 155 RPM. This would be for a 1085 RPM engine. EXAMPLE 2 Since most of the available engines started more efficiently at 3000 RPM or above, a very high reduction ratio is required. As illustrated in Figures 10 (a) and 10 (b), the desired ratio can be easily achieved previously with the unitary 2-chain mechanical module and the previously described planetary gear configuration. Using an electric motor having an optimum rotational capacity of about 3000 R.P.M., a bicycle speed of approximately 12 MPH can be achieved as follows. By reference to Figures 10 (a) and 10 (b) above, SI = 1", S2 = 4", S3 = 1"and S4 = 4 1/2." Thus, a gear reduction ratio of about 18 or 20 is realized and the RPM speed prior to the bicycle wheel can be achieved. It will be understood that variations in the embodiments of the invention are possible. For example, the invention can be applied to any of the front wheels of the bicycle or the rear wheel, in a similar manner as is described in the foregoing by the application of the invention to the rear wheel. This is achieved quickly, as the power cable from the appropriately placed battery is flexible and can be easily adapted to reach the gear motor. In yet another variation, the mounting frame may have a cavity extension collar to which it may be attached by a support to the interior of the target wheel tooth, such that the target wheel tooth freely rotates on the extension collar of the tooth. cavity. In yet another variation, the present invention can be applied to numerous applications where the advantages of implementing the invention can be gained, such as mopeds, scooters, and motorcycles.; three wheeled vehicles that include vehicles such as tricycles, four-wheel vehicles that include wheelchair vehicles, surrey style, golf cart style, and delivery style; multi-wheeled vehicles, material handling systems that include conveyors and selection and location style systems, and robotics. In another variation of the invention, the target wheel may extend beyond a spoke wheel to any target wheel of any propulsion system.

While the relative community of the lightning weave pattern and configuration is important, this is not critical to carrying out the invention. For example, in a solid "disk" wheel, the disk must have mounting holes that join the wheel in such a way to maintain concentricity with the wheel. In still yet another variation, the invention can be applied to various drive sources including electric motors, gasoline engines, or any other type of rotary drive source that would be suitable for mounting to a mounting frame of the present invention. In still a further variation, the mounting frame may include a receiving collar, a strip or other suitable mechanical connection that allows the target coupling to be precisely aligned with the mounting frame. In this way, an opening in the mounting plate is not necessarily required. The embodiments described in the foregoing provide a number of significant advantages. For example, because the propulsion system consists of the motor, the pinion wheel tooth, the clutch, the target wheel tooth, and the target wheel, this invention keeps the entire propulsion system within the same reference frame assigned by the assembled plate, so it inhibits the propulsion system tolerances within the propulsion system. These tolerances are determined by the manufacturing tolerances of the components of the propulsion system as designed independent of vehicle manufacturing tolerances. This allows the propulsion system to be applied to any vehicle, while maintaining the operation of the propulsion system. This mounting frame reference is formed by the target wheel tooth or disc with the cavity extension collar and the grooved surface that forms a wheel pattern. This disc provides to join the assembly with the wheel through the grooved surface that joins with the axis of the wheel and the spokes. The disc remains concentric with the axis of the wheel. The wheel tooth engagement is either attached to the reference frame disc through any freewheel clutch or directly attached to the reference frame disc. The motor mounting frame is attached to the reference frame disc through a bracket on the collar of the disc cavity extension. The motor is attached to the motor mounting frame, in such a way as to provide proper engagement of the pinion and the drive (or wheel tooth) gears, independent of the axle and bearing tolerances of the wheel axle. The pinion wheel tooth is directly attached to any motor directly, or through a roller clutch form, which depends on whether the gear (or tooth wheel) actuator has a free transport clutch. The radio mounting frame is attached to the bicycle frame to prevent rotation of the mounting frame. In this way, the drive and the target elements are properly aligned to a single frame of the reference. This unitary or integral feature of the propulsion system that is self-contained can be demonstrated by holding the complete assembly by hand and pulling it off. It should be noted that this invention avoids the assembly of the wheel axle, and as a result the tolerance of the problems associated with the axle and the support must be avoided. This is a significant, important aspect of this invention, and separates it from other drive systems. Another important advantage of the invention includes the fact that the tolerances of the propulsion system are independent of the vehicle. The pinion wheel tooth is held to the drive gear by the tolerances of the propulsion system, instead of the tolerances of the axle or frame support of the bicycle. The axis of the pinion wheel tooth and the motor are kept parallel with the wheel and the target wheel tooth by the tolerances of the propulsion system, specifically the mounting frame and the reference of the target wheel tooth. In the case of using gears, the gearing of the pinion wheel tooth (or pinion) and the target wheel tooth gears are maintained to the tolerances of the propulsion system. Thus, the reference frame disc provides the stable connection of the propulsion assembly to the wheel. Of course, it should be understood that a wide range of changes and modifications can be made to the preferred embodiment described above. It is therefore thought that the foregoing detailed description will be understood to be the claims including all equivalents, which are intended to define the scope of this invention.
