The invention discloses a middle-mounted wheel core driving electric driving automatic speed change system. The system comprises a power input mechanism, a driving wheel, a gear shifting transmissionmechanism arranged on a middle shaft outside the wheel, a middle shaft inside the wheel connected with the middle shaft outside the wheel through a chain transmission assembly, and a speed reduction output mechanism arranged on a wheel mounting shaft, wherein the gear shifting transmission mechanism comprises a single-side synchronizer, an overrunning clutch and a speed reduction assembly. The system is advantaged in that the speed reduction output mechanism is additionally arranged at the wheel core position of the driving wheel, the speed reduction ratio is increased, and therefore a high-speed motor can be adopted for driving, motor efficiency is greatly improved, the endurance mileage is increased, meanwhile, a chain transmission mode is reserved, and acceleration and deceleration impact of the two-wheeled vehicle can be buffered; the distance change between the chain wheels caused by up-and-down oscillation of a suspension system is reduced, two-gear gear shifting can be achieved,the electric two-wheeled vehicle has the high climbing and heavy load capacity, the motor can be located on an efficient platform all the time, and motor efficiency is further improved.

    本发明公开了一种中置式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换挡传动机构、通过链条传动组件与轮外中间轴连接的轮内中间轴以及设置在车轮安装轴上的减速输出机构,换挡传动机构包括单侧同步器、超越离合器和减速组件。采用以上方案,在驱动轮的轮芯位置增设减速输出机构,增大了减速比,从而能够采用高速电机作为驱动,大幅提高了电机效率,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,进一步提高了电机效率。
