The invention relates to the technical field of electric power-assisted mid-motor assemblies, in particular to a fast-to-install large-reduction-ratio electric power-assisted mid-motor assembly. According to the technical scheme, a motor shell comprises a first shell body and a second shell body which are assembled in a butt joint mode, the second shell body is detachably connected with one end of a bicycle five-way pipe, and the other end of the bicycle five-way pipe is connected with a locking nut; the speed-reducing power-assisting mechanism comprises an epicycloidal gear, a middle cycloidal gear, a cycloidal output gear, a motor stator and a motor rotor, wherein the motor stator and the motor rotor are coaxially arranged with the epicycloidal gear, the middle cycloidal gear and the cycloidal output gear to reduce the axial thickness of the motor assembly. On the basis of an existing traditional bicycle, a middle shaft, a crank and pedals of an original bicycle are detached, the device is installed at a five-way pipe, and building of an electric power-assisted bicycle driving system is achieved; according to the invention, the motor rotor, the motor stator and other driving structures are coaxially arranged with the epicycloidal gear, the middle cycloidal gear, the cycloidal output gear and other speed reducing mechanisms, so that the axial thickness of the motor assembly can be reduced.
本发明涉及电助力中置电机总成技术领域,尤其涉及一种快捷安装式大减速比电助力中置电机总成。其技术方案包括:所述电机壳体包括相互对接组装的第一壳体与第二壳体,所述第二壳体与自行车五通管一端可拆卸式连接,所述自行车五通管另一端连接锁紧螺母;所述减速助力机构包括外摆线轮、中间摆线轮、摆线输出轮以及与三者同轴布置以缩小电机总成轴向厚度的电机定子和电机转子。本申请可以在已有传统自行车的基础上,通过将原车的中轴、曲柄、脚踏拆除,在五通管处安装本装置,实现电助力自行车驱动系统的搭建;本申请将电机转子、电机定子等驱动结构与外摆线轮、中间摆线轮、摆线输出轮等减速机构同轴设置,可减少电机总成的轴向厚度。
