An electric auxiliary motor module is characterized in that a motor in a shell drives a wave generator with a speed reduction structure, so that the wave generator is matched with a rigid gear to drive a flexible gear, a connecting seat is formed on the inner periphery of a ring piece at the front end of the flexible gear, and the connecting seat is provided with a connecting thread section and a connecting friction surface which are adjacent to each other; a connecting piece is locked through the connecting thread section in a screwed mode, the connecting friction face abuts against the connecting piece to generate friction force so that transmission can be achieved, and the connecting piece driven by the motor and a crankshaft penetrating through the shell in a pivoted mode can drive a fluted disc base to drive a fluted disc of the electric bicycle through one-way ratchet wheel structures respectively. The effect of electrically assisting bicycle power is achieved; due to the fact that the connecting piece and the connecting base do not need to be locked through a plurality of fixing pieces, and the flexible gear is in a cup shape instead of a cap shape, the weight can be reduced, the axial size and the radial size can be shortened, and the requirements for light weight of a bicycle and miniaturization of a motor module can be met for being arranged on a five-way pipe of the bicycle.

    一种电动辅助马达模块,是在外壳内的马达驱动一减速构造的波产生器,使其配合刚性齿轮带动一柔性齿轮,所述柔性齿轮在其前端的环片内周缘形成一连接座,所述连接座具有相接邻的连接螺纹段及连接摩擦面,以连接螺纹段螺锁一连接件,并以所述连接摩擦面抵靠于所述连接件产生摩擦力而能传动,使所述马达驱动的连接件及枢穿所述外壳的曲柄轴能各自通过单向棘轮构造驱动一齿盘座带动电动自行车的齿盘,达到电动辅助自行车动力的效果;由于所述连接件与所述连接座之间无需使用多个固定件锁紧且柔性齿轮采杯型而非帽型,故能减轻重量并缩短轴向、径向的体积,满足自行车轻量化与马达模块小型化可供设置于自行车五通管的需求。
