Abstract

The invention relates to a double motor wheel edge drive system of an electric vehicle. The double motor wheel edge drive system includes a reduction gearbox, a left wheel in transmission with a lefthaft shaft, and a right wheel in transmission with a right half shaft, the double motor wheel edge drive system further includes a motor M1 and a motor M2 which are integrally fixed to the same side of a reduction gearbox shell and arranged in the longitudinal direction of the vehicle, and the reduction gearbox shell is internally provided with a left transmission assembly for realizing transmission between the left half shaft and the motor M2 and a right transmission assembly for realizing transmission between the right half shaft and the motor M1. Compared with the prior art, the double motor wheel edge drive system has the advantages that the space is saved, compactness and integration are improved, the structure is simple, the manufacturing cost is low, two-stage deceleration is realized, and requirements for performance of the drive motors are lowered.

Description

technical field [0001] The invention relates to the field of drive and transmission of electric vehicles, in particular to a dual-motor wheel side drive system for electric vehicles. Background technique [0002] Compared with traditional fuel vehicles, pure electric vehicles have many advantages such as zero emission, high efficiency, quiet and smooth operation, and are an important trend in the future development of automobiles. According to the drive system configuration, pure electric vehicles are mainly divided into two categories: centralized drive and distributed drive. Compared with centralized drive electric vehicles, distributed drive electric vehicles have outstanding advantages such as short drive transmission chain, high transmission efficiency, and compact structure. In addition, because the wheel drive torque is independently controllable, the vehicle dynamics control performance is better. It can greatly improve the active safety performance of the vehicle. ...
