无级变速器
摘要：
一种无级变速器(CVT)可以与电马达结合使用以促进对自行车骑车者的动力辅助。在一些实施例中，该CVT和马达是安装在该自行车的框架上、位于该自行车的后轮轮毂前方的位置处。在一些实施例中，该CVT是安装在该自行车框架的多个构件上并且由这些构件所支撑，从而使得该CVT是与该自行车的曲柄轴同轴的。该曲柄轴被配置成用于驱动该CVT的多个元件，这些元件被配置成用于操作性地驱动这些牵引环和这些牵引行星件。在一些实施例中，该马达被配置成用于驱动该CVT的多个元件。在其他实施例中，该马达被配置成用于驱动该曲柄轴。披露了用于这样的CVT的创造性的部件和组件。
摘要（英）：

A continuously variable transmission (CVT) can be used in concert with an electric motor to facilitate power assistance to a rider in a bicycle. In some embodiments, the CVT and motor is mounted on the frame of the bicycle at a location forward of the rear wheel hub of the bicycle. In some embodiments, the CVT is mounted on and supported by members of the bicycle frame such that the CVT is coaxial with the crankshaft of the bicycle. The crankshaft is configured to drive elements of the CVT, which are configured to operationally drive the traction rings and the traction planets. In some embodiments, the motor is configured to drive elements of the CVT. In other embodiments, the motor is configured to drive the crankshaft. Inventive component and subassemblies for such a CVT are disclosed.
