The invention provides a multi-gear electric drive system and a vehicle with the multi-gear electric drive system, and the multi-gear electric drive system comprises an input shaft, an output shaft, a motor and a motor, the planet row is connected with the driving motor, and the planet row is provided with a fixing piece which is kept static relative to the shell and a plurality of transmission pieces which rotate relative to the shell; the sliding part is arranged on the input shaft in a sleeving mode in an axial sliding mode, the sliding part is provided with a first position connected with one of the transmission parts and a second position connected with one of the other transmission parts, and the planet row transmits power to the input shaft through the sliding part; the output shaft is connected with the input shaft through a transmission assembly. According to the multi-gear speed reducer, multi-gear output of the output shaft is achieved through the planet row, compared with a single-gear speed reducer, the driving motor can work in a high-efficiency interval, the energy consumption of the driving motor is reduced, the development difficulty of the driving motor is lowered, and the economic performance of the whole vehicle is improved.

    本发明提供了一种多挡电驱系统及具有其的车辆,多挡电驱系统包括:输入轴,输入轴可轴向转动地设于壳体上;行星排,行星排与驱动电机连接,行星排具有与壳体保持相对静止的固定件,以及具有相对壳体转动的多个传动件;滑动件,滑动件可轴向滑动地套设在输入轴上,滑动件具有与其中一个传动件连接的第一位置,和与其余的传动件中的一个连接的第二位置,行星排通过滑动件将动力传递至输入轴;输出轴,输出轴通过传动组件与输入轴连接。在本发明中,利用行星排实现输出轴的多挡输出,较单挡减速器而言,驱动电机能够工作在高效率区间,降低驱动电机的能耗,降低驱动电机开发难度,改善整车的经济性能。
