摘要： A multi-speed transmission for transmitting power between a first shaft and a second shaft includes a plurality of gear sets, a plurality of connector gears corresponding to the plurality of gear sets and a shifting mechanism. Each gear set includes a first gear rotatably disposed about the first shaft, a uni-directional free wheeling mechanism between the first gear and the first shaft, and a second gear coupled to the second shaft. The uni-directional free wheeling mechanism permits the first gear to freely rotate about the shaft when the first gear rotates in a preselected direction relative to the rotation of the first shaft and locks the first gear to the first shaft at all other times. The first and second gears are spaced apart from one another but may be interconnected by one of the plurality of connector gears. Each connector gear is movable between an engaged position and a disengaged position. In the engaged position, each connector gear mutually engages the first gear and the second gear of the gear set. In the disengaged position, each connector gear is disengaged from the first gear and the second gear. The shifting mechanism moves each one of the plurality of connector gears between the engaged position and the disengaged position. The shifting mechanism maintains at least one of the plurality of connector gears in the engaged position at all times.

摘要： A variable-speed gear mechanism comprises a pinion with spring-biased radial pins and a face gear with an operative face that meshes with the pinion at various meshing radii. The gear has a central part which defines a radially innermost set of part-cylindrical sockets. Each socket has an axial opening which faces outwardly from the gear face and a lateral opening which faces radially outwardly and through which a pin is received laterally into the socket during meshed operation. A recess extends radially outwardly and in both circumferential direction from the bottom of the lateral opening of each socket, permitting unobstructed movement of a pin to and from the socket. A circular groove may define the required recesses. Its depth at a particular radius may be sufficient to avoid contact between the pins and the face gear thereby providing a neutral function. Meshing structure at a next larger meshing radius may consist of another set of sockets with lateral openings facing radially inwardly. Radial grooves may direct a pin located in a socket of the innermost set to a corresponding socket in the other set as the pinion is moved radially to change gear ratios.
摘要翻译：变速齿轮机构包括具有弹簧偏置的径向销的小齿轮和具有在各种啮合半径处与小齿轮啮合的操作面的平面齿轮。齿轮具有限定径向最内侧的部分圆柱形插座的中心部分。每个插座具有从齿轮面向外的轴向开口和面向径向向外的侧向开口，并且在啮合操作期间销通过该侧向开口被插入到插座中。凹部从每个插座的横向开口的底部沿圆周方向径向向外延伸，从而允许销与插座之间的畅通无阻的运动。圆形槽可以限定所需的凹槽。其在特定半径处的深度可能足以避免销和面齿轮之间的接触，从而提供中性功能。下一较大啮合半径处的啮合结构可由具有侧向开口面向径向向内的另一套插座组成。当小齿轮径向移动时，径向槽可以将最内侧组件的插座中的销引导到另一组中的相应插座，以改变传动比。

摘要： This invention relates to bicycles, specifically to an improved speed changing mechanism for a bicycle. The primary attribute of this invention is the utilization of a pair of pinion shafts and a pair of face gears to accomplish variation in speed. The face gear teeth and pinion are designed so that only one pair of teeth mesh at a time so that effectively they run as a pair of spur gears. The pinion shafts both forward and aft float inside a telescopic sleeve which allows a large number of gear ratios to be installed on the bicycle. The telescopic sleeve functions as a drive shaft connecting the output of the crank to a follower. The cyclist can select a gear ratio at the crank end by positioning the forward pinion. The aft pinion is positioned by a cable plus a cable lever. The invention eliminates the chain and provides a constant speed ratio at the crank. The telescopic sleeve eliminates the tension in the chain and will increase bearing life. The invention does not require major modifications to the bicycle because the free wheel mechanism and crank are not disturbed.
摘要翻译：本发明涉及自行车，具体涉及用于自行车的改进的变速机构。本发明的主要特征是利用一对小齿轮轴和一对面齿轮实现速度变化。齿轮齿和小齿轮被设计成一次只啮合一对齿，从而有效地作为一对正齿轮运行。前后的小齿轮轴在伸缩套筒内浮动，允许在自行车上安装大量的传动比。伸缩套筒用作将曲柄的输出连接到从动件的驱动轴。骑自行车者可以通过定位前进小齿轮来选择曲柄端处的齿轮比。尾部小齿轮由电缆加上电缆杆定位。本发明消除了链条并且在曲柄处提供恒定的速度比。伸缩套筒消除了链条中的张力，并将增加轴承寿命。本发明不需要对自行车进行大的修改，因为自由轮机构和曲柄不受干扰。

摘要： A multi-speed transmission has particular usefulness in bicycles, completely eliminating the use of the commonly used derailleur and the exposed flexible cable and the readjustment problems inherent with that prior structure. The transmission includes separate concentric gear rings which to a certain extent operate independently of each other. A shift mechanism for shifting the transmission is such the transmission can not be shifted from one gear to a non-adjacent gear without stopping at a gear therebetween. That is, no gear can be skipped. This is accomplished by a particular relationship of a pawl, a pusher, a shift segment plate and barrels mounted on the shift segment plate, among other parts.
摘要翻译：多速变速器在自行车中特别有用，完全消除了常用的拨链器和暴露的柔性电缆的使用以及该现有结构所固有的重新调整问题。变速器包括在一定程度上独立于彼此操作的单独的同心齿圈。用于移动变速器的换档机构是这样的，即，变速器不能在不停止在其间的齿轮的情况下从一个档位转移到不相邻的档位。也就是说，不能跳过任何齿轮。这是通过棘爪，推动器，换挡段板和安装在换档挡板上的桶的特定关系等来完成的。

摘要： A transmission gear mechanism having a plurality of drive gears and a shiftable driven gear. Eccentric gears are provided between the drive gears to smoothly transfer the driven gear from one drive gear to the next during shifting without interrupting the power transmission. Bearing surfaces are provided to bias the driven gear into contact with the drive and eccentric gears at all times to maintain power transmission.

摘要： A gear drive comprising one or more gear stocks, each gear stock including a plurality of concentric gears arranged in a predetermined size progression order along a shaft and being engaged to a preselected level of torsional engagement to rotate with respect thereto. The respective stock gears transmit torque to the shaft by a frictional engagement mechanism comprising a plurality of washers interspaced between adjacent gears, with at least the end sliding washers making positive torsional engagement with the shaft, and an axial spring compressing the stock gears against the washers, and against each other through the washers, to a predetermined level of frictional engagement. An idler gear is carried in a yoke slidably and pivotally engaged at one end thereof to a shaft in parallel alignment with the stock gear shaft, where the other end of the yoke engages steps in a register slot, located to correspond to the engagement positions of the respective stock gears with the idler gear. The idler gear also simultaneously engages a driven gear, which in one of the embodiments can be any one gear of a second gear stock constructed substantially as set forth above, to provide a preselected gear ratio. At either end of the drive change gears are combined with said gear drive to provide a predetermined torque or speed advantage.

摘要： A changeable speed gear attachment for mounting on a standard bicycle without the need for modification of the bicycle is disclosed. The attachment includes a housing which mounts on the frame of the bicycle and includes a driving pinwheel gear having several adjacent concentric rows of teeth, a driven pinwheel gear having at least one row of teeth, a driving pinion gear operating off the driving pinwheel gear and slidably mounted so as to selectively engage one of the several rows of teeth, and a driven pinion gear which is driven by the driving pinion gear and which, in turn, drives the driven pinwheel gear. The pinwheel gears are each connected to a sprocket externally of the housing and the sprockets are connected to the sprockets of the bicycle by means of conventional bicycle chains.
