The invention discloses an electric driving system, a power system of an electric automobile and the electric automobile, the electric driving system comprises a shell, two driving motors and two speed reducers, the two driving motors are arranged on the shell, the two driving motors are provided with motor output shafts, the two motor output shafts are coaxially arranged, the two speed reducers are arranged on the shell, and the two speed reducers are coaxially arranged on the shell. The two speed reducers are symmetrically arranged on the outer sides of the two driving motors at intervals, each speed reducer comprises a first planet row and a second planet row, the first planet row is in transmission connection with one driving motor, the second planet row is arranged on the first planet row in a sleeving mode and is in transmission connection with the first planet row, and the output end of the second planet row is used for being in transmission connection with a wheel on one side. According to the technical scheme, through the two driving motors and the two speed reducers which are independently arranged, independent driving of the wheels on the two sides is achieved, the axial distance is shortened, the overall structure is more compact, the problems that a traditional parallel shaft is large in axial distance and difficult to arrange are solved, the structural bearing requirement is small, and efficiency is improved.

    本发明公开一种电驱动系统、电动汽车的动力系统和电动汽车,电驱动系统包括壳体、两个驱动电机和两个减速器,两个驱动电机设于壳体,两个驱动电机具有电机输出轴,两个电机输出轴同轴线设置,两个减速器设于壳体,两个减速器间隔且结构对称设置于两个驱动电机外侧,每一减速器包括第一行星排和第二行星排,第一行星排传动连接一驱动电机,第二行星排套设第一行星排且与第一行星排传动连接,第二行星排的输出端用以传动连接一侧车轮,本发明技术方案通过独立设置的两个驱动电机和两个减速器,实现两侧车轮的单独驱动,缩短了轴向距离,整体结构更紧凑,解决了传统平行轴轴向距离大、不好布置的问题,结构承载需求小、提高效率。
