An electric auxiliary driving system for a bicycle comprises a pedal shaft (1), a planetary gear mechanism (20), an auxiliary motor (M2) used for driving an output shaft (21) and a control motor (M1), and the transmission ratio between the pedal shaft (1) and the output shaft (21) is controlled through the planetary gear mechanism. A first one-way clutch (10) operably connected to the control motor (M1) and configured to prevent rotation of a rotatable member (4) of the planetary gear mechanism in a forward direction while allowing free rotation thereof in a reverse direction. A second one-way clutch (12) is configured to drivingly connect the auxiliary motor (M2) to the output shaft (21) when the auxiliary motor (M2) is turned on and to disengage the auxiliary motor (M2) from the output shaft (21) when the auxiliary motor is turned off but the output shaft (21) continues to rotate forward.

    一种用于脚踏车的电动辅助驱动系统,包括一踏板轴(1)、一行星齿轮机构(20)、用以驱动一输出轴(21)的一辅助马达(M2)以及一控制马达(M1),透过行星齿轮机构来控制踏板轴(1)与输出轴(21)之间的传动比。一第一单向离合器(10),可操作地连接到控制马达(M1),配置用以阻止行星齿轮机构的一可旋转构件(4)在一向前方向上的旋转,同时允许其在反向自由旋转。一第二单向离合器(12)配置以当辅助马达(M2)被开启时将辅助马达(M2)驱动地连接至输出轴(21),并且当辅助马达关闭但输出轴(21)继续向前旋转时用以将辅助马达(M2)从输出轴(21)分离。
