The invention provides a power module of an electric power-assisted bicycle. A power module of the electric power-assisted bicycle comprises a pedal shaft, a fluted disc output shaft, a speed reducer output shaft and a motor output shaft. The pedal shaft is arranged in the axial direction. The fluted disc output shaft comprises a first section and a second section which are arranged in the axial direction, the inner diameter of the first section is larger than the outer diameter of the second section, and the pedal shaft is concentrically sleeved with the first section through a first one-way bearing in the radial direction. When the pedal shaft is stressed to rotate, the first one-way bearing drives the fluted disc to extend out of the shaft. The speed reducer output shaft is concentrically arranged on the outer side surface of the second section in a sleeving mode through a second one-way bearing in the radial direction. And the motor output shaft is concentrically sleeved on the speed reducer output shaft along the radial direction. When the motor output shaft drives the speed reducer output shaft to rotate, the speed reducer output shaft drives the fluted disc output shaft through the second one-way bearing.
本发明提供一种电动助力自行车的动力模块。电动助力自行车的动力模块包括脚踏轴、齿盘出轴、减速机输出轴以及电机出轴。脚踏轴沿轴向设置。齿盘出轴包括具有沿轴向排列的第一区段及第二区段,第一区段的内直径大于第二区段的外直径,且第一区段通过第一单向轴承沿径向同心地套设于脚踏轴。脚踏轴受力转动时通过第一单向轴承驱动齿盘出轴。减速机输出轴通过第二单向轴承沿径向同心地套设于第二区段的外侧表面。电机出轴沿径向同心地套设于减速机输出轴上。电机出轴驱动减速机输出轴转动时,减速机输出轴通过第二单向轴承驱动齿盘出轴。
