The invention provides an electric automobile driving device and system and an electric vehicle. The electric automobile driving device is arranged on a chassis of the electric automobile, and the electric automobile further comprises a plurality of wheels arranged on the chassis. The electric automobile driving device comprises a plurality of motors and speed reducers, the number of the motors isequal to that of the wheels, the speed reducers are mechanically connected with the motors respectively, and each speed reducer is further mechanically connected with one wheel, wherein each motor isused for driving one wheel through one speed reducer. Compared with the prior art, a differential mechanism does not need to be arranged, the power loss between devices is reduced, and each wheel canbe driven more flexibly by adopting a distributed driving structure. Besides, the electric automobile driving device is arranged on the chassis of the electric automobile, so that the gravity centerof the electric automobile is reduced, and the running stability of the whole automobile is improved.

    本申请提供一种电动汽车驱动装置、系统以及电动汽车。所述电动汽车驱动装置设置在电动汽车的底盘上;所述电动汽车还包括设置在所述底盘上的多个车轮;所述电动汽车驱动装置包括:多个电机,所述电机的数量与所述车轮的数量相等,以及与每个所述电机机械连接的减速器,每个所述减速器还与一个所述车轮机械连接;其中,每个所述电机用于通过一个所述减速器进而驱动一个所述车轮。与现有技术相比,无需再设置差速器,减少了器件之间的动力损失,并且采用分布式驱动结构可以对每个车轮的驱动更加灵活。此外,该电动汽车驱动装置是设置在电动汽车的底盘上的,降低了电动汽车的重心,提高了整车行驶的稳定性。
