摘要： A continuously variable friction drive transmission for a bicycle is provided by driving the rear bicycle wheel by frictional engagement with a rotating rim driver. The rim driver has a lateral conical surface matching a lateral conical surface of a driver plate. A transmission driver wheel is selectively positioned between the lateral conical surfaces of the rim driver and driver plate. The position along a shifting arm of the transmission driver wheel determines the speed ratios obtained between the driver plate and rim driver. The driver plate is then rotated by the pedal assembly through a speed increasing coupling. The transmission driver wheel is always in contact with the driver plate. When the driver plate ceases to rotate and the rear wheel and rim driver continue to rotate, the force on the transmission driver wheel automatically rotates the shifting arm on which the transmission driver wheel is coupled to kick the transmission driver wheel out of engagement with the conical surface of the rim driver thereby allowing the rear bicycle wheel to freewheel. The transmission driver wheel is returned into mutual engagement between the conical surfaces of the driver plate and rim driver, when the driver plate again rotates at a speed fast enough to couple the driver plate and rim driver again into a force transmitting relationship.
摘要翻译：通过与旋转轮辋驱动器摩擦接合来驱动后自行车车轮来提供用于自行车的连续可变的摩擦驱动传动装置。轮辋驱动器具有与驱动器板的侧向圆锥形表面匹配的侧向锥形表面。传动驱动轮被选择性地定位在轮辋驱动器和驱动器板的侧向圆锥形表面之间。沿传动驱动轮的移动臂的位置决定了驱动板和轮辋驱动器之间获得的速比。然后驾驶员板通过踏板组件通过增速联轴器旋转。传动驱动轮始终与驱动板接触。当驾驶员板停止旋转并且后轮和轮辋驾驶员继续旋转时，变速器驱动轮上的力自动旋转传动驱动轮连接的变速臂，以使变速器驱动轮脱离与锥形从而允许后自行车车轮飞行。当驱动板再次以足够快的速度旋转以将驱动器板和轮辋驱动器再次耦合到力传递关系时，变速器驱动轮被返回到驱动器板和轮辋驱动器的锥形表面之间的相互接合。

摘要： To encourage the use of bicycles for both recreation and transportation by reducing the normally excessive load on the cyclist during hill climbing. A simple on/off push button controls the power assist while a clutch automatically handles both engagement and disengagement. The invention enables a powerful (80 to 150 watts of power delivered to the bicycle tire), compact, lightweight (2.5 to 4 kg) system capable of boosting a cyclist during the hills of a 1 to 2 hour bicycle ride. The system is compatible with most bicycles, is easy to install yet includes a theft deterrent mount. The system includes several safety features including a very modest high speed limit (e.g. 12 mph) beyond which power assist is automatically disabled, and a modest power level which can be overridden by normal bicycle brakes.

摘要： A variable speed shaft drive system for bicycles employs a drive shaft that is generally horizontally coupled between the pedals and the rear wheel of the bicycle. A pinion gear at the forward end of the drive shaft is engaged by a ring gear driven by the pedals to transmit drive power from the pedals to the drive shaft. A drive head at the rear end of the drive shaft frictionally engages a drive pick-up plate mounted to the rear wheel of the bicycle to transmit drive power from the rotating drive shaft to the rear wheel. Infinitely variable speed control is achieved by means of a shifting fork actuated by the user to position the drive head at selected distances from the center of the drive pick-up plate. Alternatively, a second drive head/pick-up ring combination may be substituted for the ring gear/pinion gear combination driven by the pedals to provide even smoother operation. The second drive head may be positioned a fixed distance from the center of its associated pick-up ring or it may also be made variable, resulting in a dual variable speed shaft drive to provide a greater range of speed ratios selectable by the rider.

摘要： A friction drive for a vehicle wherein a friction drive wheel is mounted to engage frictionally the pneumatic tire constituting the periphery of a vehicle traction wheel, such drive wheel being carried on a strut mounted to swing about an axis remote therefrom and which is parallel to and spaced from the axis of the traction wheel in an arrangement such that the strut is subjected to a reaction torque in response to driving friction force in one direction which in turn urges the center of the drive wheel towards the center of the ground wheel. The drive wheel is of lesser diameter than the traction wheel so as to effect a reduction in rate of rotation, and is of frusto-conical configuration so that a variation in drive ratio can be driven by a storage battery powered direct current motor, with the batteries carried either on the vehicle or on a trailer towed thereby.

摘要： A transmission for a pedal-propelled vehicle has a drive shaft rotated by a crankset and disposed radially with respect to the driving wheel of the vehicle. A friction wheel is slidably connected to the shaft by a one-way clutch and is in engagement with a friction member connected to the driving wheel to rotate therewith. The friction wheel includes a tubular shaft through which the drive shaft extends. A shifting unit is connected to the friction wheel by means of the tubular shaft to slide along the drive shaft therewith but is held against turning. The shifting unit includes a gear train having a pinion in mesh with a fixed rack parallel to the drive shaft. First and second normally inoperative connections between the tubular shaft and the gear train are provided, the first to drive the gear train to rotate the pinion to shift the unit and the friction wheel towards the axis of the friction member and the second to drive the gear train to shift the unit and friction wheel towards the periphery thereof. The connections are made by a control including means responsive to the speed of the tubular shaft and means, adjustable by the operator, resiliently opposing the speed responsive means. When the speed responsive means is dominant, the first connection is rendered operative, when the resilient means is dominant, the second connection is rendered operative, and when neither means is dominant, a neutral is established with neither connection operative, the transmission thereby effecting ratio changes in relation to the wanted rate of pedalling or cadence that is established by the resilient means.

摘要： A bicycle propelling means employing an electric motor having a cone-shaped driving roller which engages one side of the bicycle tire. A cylindrical, freely-rotating roller engages the opposed side of the tire to assure positive contact between the coneshaped roller and the tire. An increase or decrease in the rate of travel of the bicycle is obtained by shifting the periphery of the cone-shaped roller in a plane common to the side of the tire, thus engaging the tire at varying diameters of the roller; The rate of travel then being directly proportional to the diameter of the cone-shaped roller in contact with the tire.

摘要： The present invention disclose a continuously variable reciprocating prime mover. The feature of this continuously variable reciprocating prime mover is that the reciprocating rotatory motion of the legs is modified into the reciprocating linear flexion and extension of the legs, by which one leg is flexed while the other leg is stretching, the combined force of the legs can be multiplied by the force. After each linear motion stroke is completed, the reverse linear motion stroke is repeated, and the driving direction remains unchanged. At any moment of the full stroke of the reciprocating linear flexion and extension of the legs, both can generate 2 times of the instantaneous power equivalent to the maximum moment point of the circular rotation.

摘要： Compared to derailleur bicycle chain transmissions, internal hub transmissions for bicycles have higher friction and a lower torque capacity. In addition, bicycle hub transmissions are generally incompatible with alternate drive arrangements such as direct-drive, or different mounting options such as mono-blade mounting. The present invention addresses these concerns by employing bevel gears with roller teeth in a planetary bicycle hub transmission. The bevel gear configuration allows larger planet gears, which gives sufficient circumferential space for roller teeth to reduce the meshing friction. The larger planet gears also increase the allowable torque. Furthermore, the bevel gear configuration facilitates the high ratios required for direct-drive, and results a hub structure highly compatible with mono-blade mounting. With this is view, the hub is designed for both chain-drive and direct-drive, and for both double-blade and mono-blade mounting.
摘要翻译：与拨链器自行车链条变速箱相比，自行车的内部轮毂传动装置具有更高的摩擦力和更低的扭矩能力。此外，自行车轮毂变速器通常与诸如直接驱动或诸如单刀片安装的不同安装选项的替代驱动装置不兼容。本发明通过在行星式自行车轮毂传动装置中采用带齿轮的锥齿轮来解决这些问题。锥齿轮配置允许更大的行星齿轮，这为滚齿提供足够的周向空间，以减少啮合摩擦。较大的行星齿轮也增加了允许扭矩。此外，锥齿轮配置有助于直接驱动所需的高比率，并且导致与单刀片安装高度兼容的轮毂结构。有了这个观点，该轮毂设计用于链驱动和直接驱动，以及双刀片和单刀片安装。
