The invention relates to a power assembly alternating gear-shifting variable-speed driving system suitable for hybrid and pure electric vehicles, which comprises a front axle and a rear axle of the vehicle respectively provided with a set of motors (an engine and a generator are additionally arranged on the front axle of the hybrid vehicle), front and rear axle electric control clutches, front and rear axle 3-4-speed electric control manual gearboxes and the like. The front and rear shaft electric control manual gearbox is alternately controlled through a computer program to shift gears (because the front and rear shafts are alternately driven in the gear shifting process, the power is not interrupted). And automatic gear shifting can be realized, so that the gear shifting process is smoother. Timely free switching of front drive, rear drive and four-wheel drive of the vehicle can also be achieved.
本发明涉及一种适用于混动和纯电动汽车的动力总成交替换档变速驱动系统,其包括:车辆前后轴各配置一套电动机(混动在前轴加配发动机和发电机)、前后轴电控离合器、前后轴3‑4速电控手动变速箱等,通过电脑程序交替控制前后轴电控手动变速箱进行换档(因换挡过程中前后轴交替驱动,动力没有中断)。可以实现自动换档使换档过程更平顺性。也可以实现车辆前驱、后驱和四驱的适时自由转换。
