摘要： A variable speed transmission having a plurality of tilting balls and opposing input and output discs is illustrated and described that provides an infinite number of speed combinations over its transmission ratio range. The use of a planetary gear set allows minimum speeds to be in reverse and the unique geometry of the transmission allows all of the power paths to be coaxial, thereby reducing overall size and complexity of the transmission in comparison to transmissions achieving similar transmission ratio ranges.

摘要： A fully automatic infinitely variable torque converter bicycle transmission makes use of cam followers acting between a driver wheel connected with an input and a follower wheel connected with an output. Torque is varied by varying a radial position of the cam followers relative to the driver wheel and the follower wheel, wherein a return of the cam followers toward an outer radial position is delayed. All force transmitting components of the apparatus are mechanically engaged without relying on friction.

摘要： A continuously variable automatic drive has a front driving sprocket and a rear driven sprocket. Each of these sprockets has a housing and a plurality of involute-shaped toothed segments, each having a leading end and a trailing free end. The toothed segments are symmetrically spaced around their housings and pivotally attached to their housings about their leading ends. Each toothed segment is movable between a first position where the trailing free end is pivoted inwardly closest to the housing and the effective diameter of the sprocket is smallest and a second position where the trailing free end is pivoted outwardly farthest from the housing and the effective diameter of the sprocket is largest. The highest gear ratio is produced when the front driving sprocket is at the second position and the rear driven sprocket at the first position. The lowest gear ratio is produced when the front driving sprocket is at the first position and the rear driven sprocket is at the second position. The springs are biased so that the gearing defaults to the highest gear ratio, at the relaxed, neutral position, where no force is applied to the driving sprocket.

摘要： The present invention is directed to an improved variable sprocket transmission of a type that is particularly well-suited for use in multi-speed bicycles. More particularly, a variable sprocket transmission for a multi-speed bicycle is provided which can be smoothly and easily shifted without noise, is reliable, and can be easily used by both experienced and novice bicyclists. The variable sprocket transmission of the present invention can be manually shifted through a sequentially ordered set of distinct speed ratios using a single shift lever or, in the alternative, can be automatically shifted without input from the bicycle rider based on measured operating parameters.

摘要： A steplessly variable-ratio drive has a drive wheel having a hub rotatable about a drive axis, adapted to be normally rotated in a forward direction about the axis, and having at least three angularly equispaced pivots radially equispaced from the axis. Respective segments each have an inner end pivoted at the respective pivot on the hub, an outer end radially offset from the respective pivot, and a radially outwardly convex curved outer surface. Respective springs braced generally radially between the outer ends of the segments and the inner ends of the adjacent segments urge the outer ends radially outward. A driven wheel has a hub rotatable about a driven axis substantially parallel to the drive axis, adapted to be normally rotated in the forward direction about the driven axis, and having a plurality of angularly equispaced pivots radially equispaced from the driven-wheel axis. Respective segments each have an inner end pivoted at the respective pivot on the driven-wheel hub, an outer end radially offset from the respective pivot, and a radially outwardly convex curved outer surface. A belt is spanned over and interconnects the wheels.

摘要： A steplessly variable transmission is described in which a driving element and a driven element are adjustable eccentrically to one another and are coupled via pivotal levers which are journalled on one element and can be brought into force transmitting clamping engagement with the other element via coupling shoes. In the context of this series connection the two change speed units are inversely combined with an eccentric positioning device being provided which either jointly actuates the members with the ring tracks associated with the coupling elements or the members with the coupling elements. The force transmitting zones of engagement of the two units are angularly displaced relative to one another and the eccentricities of the two units and also the lever arms associated with the coupling elements can be so selected that ideal transmission ratios result which are largely free of fluctuations.

摘要： A continuously variable transmission includes a power input driving a sun gear which in turn drives a plurality of planetary gears. Within each planetary gear is mounted an over-rolling clutch. The planet gear is free to rotate about its raceway in one direction and is locked from rotation in the opposite direction. The shaft mountings for each planetary gear are suitably journalled in a carrier ring rotatably mounted within the housing. An internal gear, integrally mounted within the output housing, meshes with the planetary gears and is driven by them. An eccentric system, comprised of two nested eccentrics within the housing and anchored to an axle, controls the degree of oscillation imparted to the planetary gear raceway shafts. The eccentric system is continuously positionable so as to increase the rotation of the input sun gear from a one-to-one ratio up to the maximum designed output. As the eccentricity is increased, the planetary gear system superimposes a pulse drive on the sun gear that exponentially multiplies the drive rotation rate. Thus, the output housing is driven at a greater rate of rotation than the planetary carrier. When the eccentrics are at the zero eccentricity position, the transmission operates as a direct drive with no internal gear motion.
摘要翻译：无级变速器包括驱动太阳齿轮的动力输入，所述太阳齿轮又驱动多个行星齿轮。在每个行星齿轮内装有一个过滚动离合器。行星齿轮在一个方向上绕其滚道自由旋转，并且在相反的方向上被锁定以避免旋转。用于每个行星齿轮的轴安装件适当地轴颈安装在可旋转地安装在壳体内的托架环中。整体安装在输出壳体内部的内齿轮与行星齿轮啮合并由它们驱动。偏心系统由壳体内的两个嵌套的偏心轮组成，并被固定在一个轴上，控制给行星齿轮滚道轴的摆动程度。偏心系统可连续定位，以便将输入太阳齿轮的旋转从一对一的比例增加到最大设计输出。随着偏心度的增加，行星齿轮系统将脉冲驱动器叠加在太阳齿轮上，使驱动旋转速度呈指数倍增。因此，输出壳体以比行星架更大的旋转速度被驱动。当偏心体处于零偏心位置时，变速器作为直接驱动而无内部齿轮运动。

摘要： Drive mechanism, particularly for use with a bicycle, of the type having variable diameter drive and driven members connected by an endless belt which engages adjustable segments on the members. Through a control member the drive ratio can be adjusted to multiple, discrete settings. Belt wrap is maintained between the belt and the drive and driven members at all settings by two idlers which are independently supported for movement. A locking rail is used to release and secure the segments on the members and a split clutch is used with the driven member for easy rear wheel removal. The mechanism has a lost motion device to accommodate forward and rearward pedaling without harming the drive mechanism. The drive mechanism is modular in contruction so it can be used with frames of varying sizes and the drive mechanism can be quickly removed from or assembled to the bicycle frame when replacement is desired.

摘要： A transmission means for transmitting power between input and output drives in which a rack and pinion gear assembly and a cam adjacent the pinion cooperate with the drives to provide a variable gear ratio therebetween. The gear assembly includes inner and outer gear rack pairs, in which such gear rack pair has oppositely facing toothed rack portions which are spaced apart sufficiently to receive the pinion gear and cam therebetween, with an outer surface of the cam adjacent at least one of the oppositely facing toothed rack portions. Resilient connectors interconnect the end portions of each pair of toothed rack portions to as to permit limited resilient movement between the rack portions of each pair. A rotor engages the rack pairs to transmit that power therebetween. Preferably, a gear ratio changer can vary spacing between input and output axes in such a direction as to provide a favourable change in effective radius of action of the drive in addition to the gear ratio resulting from the rack and pinion gear assembly.
