The invention discloses a middle chain transmission wheel core drive electric drive automatic speed change system. The system comprises a power input mechanism, a driving wheel, a speed reduction input mechanism, a wheel mounting shaft, a gear shifting transmission mechanism and a power output part, wherein the speed reduction input mechanism is arranged on an intermediate shaft outside the wheel,the gear shifting transmission mechanism and a power output part are arranged on the wheel mounting shaft, and the gearshift transmission mechanism comprises a double side synchronizer and a reduction component, a bilateral synchronizer can be combined with a power output component or a speed reduction assembly. The system is advantaged in that the reduction ratio is increased, so a high-speed motor can be adopted for driving, motor efficiency is improved, the endurance mileage is increased, meanwhile, a chain transmission mode is reserved, the acceleration and deceleration impact of the two-wheeled vehicle can be buffered, the distance change between chain wheels caused by up-and-down oscillation of a suspension system is reduced, and two-gear shifting can be realized; the electric two-wheeled vehicle has strong climbing and heavy load capacities, and the motor can be always located on the efficient platform.

    本发明公开了一种中置式链传动轮芯驱动电驱动自动变速系统,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均设置在车轮安装轴上的换挡传动机构和动力输出部件,换挡传动机构包括双侧同步器和减速组件,双侧同步器能够与动力输出部件或减速组件结合。采用以上方案,增大了减速比,从而能够采用高速电机作为驱动,提高了电机效率,增加了续航里程,同时保留链条传动的方式,可以缓冲两轮车加减速的冲击,减小悬挂系统上下震荡造成链轮之间的距离变化,并且能够实现两挡换挡,不仅使电动两轮车具有强大的爬坡和重载能力,而且使电机能够始终处于高效平台上。
