The invention relates to a pin shaft type cycloid hub motor, which belongs to the technical field of electric bicycles, and comprises a motor assembly and a cycloid speed reducer assembly. The cycloidspeed reducer assembly comprises a rotating arm, a cycloid planet wheel sleeving the rotating arm, and a pin wheel matched with the cycloid planet wheel; end discs used for supporting the rotating arm are arranged at the two sides of the cycloid planet wheel, the cycloid planet wheel is connected with the end discs through pin shafts, and the pin shafts are used for limiting rotation of the cycloid planet wheel. A pin wheel housing of the pin wheel is arranged on the inner side of the wheel hub and is fixedly connected to the wheel hub or is integrally designed with the wheel hub; the motor assembly is located in the side, away from the cycloid planet wheel, of the end disc and comprises a motor rotor fixed to the rotary arm and a motor stator arranged in the circumferential direction ofthe motor rotor. By adopting the pin wheel housing for output, compared with the prior art, the overload capacity and the impact resistance are high, the structure is simple and compact, and the sizeis smaller.
本发明涉及一种销轴式摆线轮毂电机,属于电动自行车技术领域,包括电机组件和摆线减速器组件,摆线减速器组件包括转臂和套设在其上的摆线行星轮,以及与摆线行星轮匹配的针轮;摆线行星轮的两侧设有用于支撑转臂的端盘,摆线行星轮与端盘之间通过销轴连接,销轴用于限制摆线行星轮的自转;针轮的针齿壳设置在轮毂的内侧,固定连接在轮毂上或与轮毂为一体设计;电机组件位于端盘远离摆线行星轮的一侧,包括固定在转臂上的电机转子和设置在电机转子周向的电机定子。本发明通过采用针齿壳输出,与现有技术相比,具有较大的过载能力和较高的耐冲击性能,而且结构简单、紧凑,体积更小。
