The invention relates to the technical field of electric power-assisted speed control systems of bicycles, and discloses an electric power-assisted speed control system and a bicycle. A shell of the electric power-assisted speed control system is provided with a rotatable first power shaft and a transmission shaft; a rotor of the motor set is connected with the driving gear, the first planetary gear set and the second planetary gear set share the same inner gear ring, and a first sun gear is arranged on the first planet carrier. The first planet gear is meshed with the inner gear ring and the driving gear; a first clutch transmission assembly is arranged between the first power shaft and the first sun gear; a plurality of second planet gears are fixedly connected with the multi-stage driving gear set and are meshed with the inner gear ring and the first sun gear; a second clutch transmission assembly is arranged between the transmission shaft and each stage of the multi-stage driven wheel set. A gear shifting convex part of the first gear shifting mechanism is propped against the first clutch transmission assembly, so that the first power shaft is in transmission connection with the first sun gear; and the gear shifting convex part of the second gear shifting mechanism is propped against any second clutch transmission component, so that the corresponding driven wheel is in transmission connection with the transmission shaft.

    本发明涉及自行车的电助力变速系统技术领域,公开了一种电助力变速系统和自行车,该电助力变速系统的壳体上具有可转动的第一动力轴和传动轴;电机组的转子连接驱动齿轮,第一行星齿轮组和第二行星齿轮组共用同个内齿圈,第一行星架上设有第一太阳轮;第一行星轮啮合内齿圈和驱动齿轮;第一动力轴与第一太阳轮之间设有第一离合传动组件;多个第二行星轮与多级主动轮组固定连接,并啮合内齿圈和第一太阳轮;传动轴和多级从动轮组的每一级之间均设有第二离合传动组件;第一换挡机构使其换档凸部抵接第一离合传动组件使得第一动力轴与第一太阳轮传动连接;第二换挡机构使其换档凸部抵接任一第二离合传动组件使得其对应的从动轮与传动轴之间传动连接。
