The invention relates to a different-shaft type automatic stepless hybrid speed change system and a power-assisted bicycle. The system comprises a motor, a controller, a harmonic drive speed reducer and a pedal through shaft. The controller is in conduction connection with the motor, and the motor is in driving connection with a wave generator of the harmonic transmission speed reducer; the pedalthrough shaft is arranged on the harmonic transmission speed reducer in a penetrating manner, one end of the pedal through shaft rotatably extends out of the wave generator of the harmonic transmission speed reducer, and the other end of the pedal through shaft extends out of a flexible gear of the harmonic transmission speed reducer and is in driving connection with the flexible gear; and a hybrid power output fluted disc is arranged on a rigid gear of the harmonic drive speed reducer. Therefore, a hybrid power mode, a pure electric mode and a pure treading mode can be selected according to riding requirements; riding is flexible and convenient, riding pleasure is high, treading riding can be kept easy and relaxed at a medium speed and a high speed, meanwhile, power transmitted by the motor and power transmitted by the pedal through shaft can be well mixed and output according to the set rotating speed proportion, stepless speed change at a stepless position is achieved, and more comfortable and more intelligent riding is achieved.
本发明涉及一种异轴式自动无段混动变速系统及助力自行车,该系统包括电机、控制器、谐波传动减速器和脚踏通轴;控制器与电机导通连接,电机与谐波传动减速器的波发生器驱动连接;脚踏通轴穿设在谐波传动减速器上,且脚踏通轴的一端可转动地从谐波传动减速器的波发生器伸出,另一端从谐波传动减速器的柔性齿轮伸出并与柔性齿轮驱动连接;谐波传动减速器的刚性齿轮上设有混合动力输出齿盘。这样即可根据骑行需要选择混合动力模式、纯电动模式和纯踩踏模式,骑行灵活、便利,骑行乐趣高,且在中速和高速时也能保持踩踏骑行容易、轻松,同时可以很好地将电机传递过来的动力和脚踏通轴传递过来的动力依据设定的转速比例混和动力输出,实现了无段位的无极变速,实现更舒适更智能的骑行。
