The invention provides a resultant force output center shaft motor of an electric bicycle. The resultant force output center shaft motor comprises a motor and a manpower module, the motor and the manpower module are assembled at a five-way position of the bicycle through a shell, the manpower module comprises a mandrel, and pedals are assembled at two ends of the mandrel; the mandrel and an output shaft of the motor are respectively in transmission connection with a resultant force assembly, the resultant force assembly and the mandrel are coaxially assembled, the resultant force assembly comprises an inner sleeve connected with power output of the manpower module and an outer sleeve connected with power output of the motor, and a middle sleeve for unidirectionally integrating resultant force of the inner sleeve and the outer sleeve is assembled between the inner sleeve and the outer sleeve; and the end part of the middle sleeve is fixedly assembled with a chain wheel. In the motor, the resultant force assembly simultaneously receives manpower and electric power transmission through the middle sleeve, compared with two traditional independent clutch structures, the motor is greatly simplified, and the two clutch structures do not interfere with each other. In addition, the component can be integrally assembled and installed, more convenience is achieved, and meanwhile the overall assembly error can be greatly reduced.

    本发明提供一种电动自行车合力输出中轴电机,它包括马达、人力模块,所述马达、人力模块通过壳体装配在自行车的五通位置,所述人力模块包括心轴,所述心轴的两端装配脚踏;所述心轴与马达输出轴分别与合力组件传动连接,所述合力组件与所述心轴同轴装配,所述合力组件包括连接人力模块动力输出的内套,连接马达动力输出的外套,所述内套、外套之间装配有单向整合二者合力的中套;所述中套的端部与牙盘固定装配。在该电机中,合力组件通过中套同时承接人力和电力的传动,比起传统的两个单独离合结构大大简化,并且两个离合结构之间不会产生干扰。另外,该部件可以整体装配安装,更加的方便,同时也可以大大降低整体装配误差。
