The invention discloses a chain type central drive electric drive automatic speed change system. The system comprises a power input mechanism, a drive wheel, a gear shifting transmission mechanism, awheel axle connected with an intermediate shaft outside the wheel through a chain transmission assembly and a speed reduction output mechanism arranged on the wheel axle, wherein the power input mechanism transmits power to the speed reduction output mechanism through the wheel outer middle shaft, the gear shifting transmission mechanism, the chain transmission assembly and the wheel shaft in sequence, and the speed reduction output mechanism drives the driving wheel to rotate. The system is advantaged in that the speed reduction transmission path is prolonged, the speed reduction ratio is increased, a high-speed motor can be adopted for driving, the motor is located on an efficient output platform, motor efficiency is greatly improved, two sides of the driving wheel are arranged in a central driving mode, the balance is good, and meanwhile a chain transmission mode is reserved; in addition, two-gear gear shifting can be achieved, the electric two-wheeled vehicle has strong climbing and heavy load capacity, and the motor can be located on the efficient platform all the time.

    本发明公开了一种链条式中央驱动电驱动自动变速系统,包括动力输入机构、驱动轮、换挡传动机构、通过链条传动组件与轮外中间轴连接的车轮轴以及设置在车轮轴上的减速输出机构,动力输入机构依次通过轮外中间轴、换挡传动机构、链条传动组件和车轮轴将动力传递给减速输出机构,由减速输出机构带动驱动轮转动。采用以上技术方案,延长了减速传动路径,增大了减速比,从而能够采用高速电机作为驱动,使电机处于高效输出平台上,大幅提高了电机效率,且驱动轮两侧采用中央驱动式的布置方式,平衡性好,同时保留链条传动的方式,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。
