The invention discloses a middle chain transmission type central electric driving system which comprises a power input mechanism, a driving wheel, a speed reduction input mechanism arranged on an intermediate shaft outside the wheel, a wheel mounting shaft connected with the intermediate shaft outside the wheel through a chain transmission assembly and a speed reduction output mechanism arranged on the wheel mounting shaft. The power input mechanism transmits power to the driving wheel through the speed reduction input mechanism, the chain transmission assembly, the wheel installation shaft, the speed reduction output mechanism and a power output component in sequence. By the adoption of the technical scheme, the advantages of a central driving structure are reserved, the motor is arrangedin the middle of the two-wheeled vehicle, the speed reducing mechanism is arranged on one side of the driving wheel, meanwhile, a chain transmission mode is adopted, the acceleration and decelerationimpact of the two-wheeled vehicle can be buffered, and the distance change between chain wheels caused by the up-and-down oscillation of a suspension system can be reduced; in addition, the speed reduction input mechanism is additionally arranged beside the power input mechanism, and the speed reduction ratio is further increased.

    本发明公开了一种中置链传动式中央电驱动系统,包括动力输入机构、驱动轮、设置在轮外中间轴上的减速输入机构、通过链条传动组件与轮外中间轴连接的车轮安装轴以及设置在车轮安装轴上的减速输出机构,动力输入机构依次通过减速输入机构、链条传动组件、车轮安装轴、减速输出机构和动力输出部件将动力传递给驱动轮。采用以上技术方案,不仅保留了中央驱动结构的优点,而且将电机设置在两轮车中间位置,将减速机构设置在驱动轮的一侧,同时采用链条传动的方式,不但可以缓冲两轮车加减速的冲击,还能减小悬挂系统上下震荡造成链轮之间的距离变化;另外,在动力输入机构旁增设减速输入机构,进一步增大了减速比。
