The invention discloses an automotive dual-motor driving device which comprises a first motor, a second motor, a third connecting gear, a third driving shaft and a synchronizer, the left end of a first driving shaft of the first motor is connected with a left half shaft, a first connecting gear is arranged at the right end of the first driving shaft of the first motor, and a second connecting gear is arranged at the left end of a second driving shaft of the second motor. The third connecting gear is arranged on the third driving shaft, the third driving shaft is connected with the right half shaft, and the synchronizer is at least switched between a first working position and a second working position: in the first working position, the synchronizer is connected with the first connecting gear and the third connecting gear, and the first connecting gear and the third connecting gear rotate synchronously; and in the second working position, the synchronizer is connected with the second connecting gear and the third connecting gear which rotate synchronously. The invention further provides a vehicle. According to the invention, single-motor and double-motor power switching can be realized, and the system efficiency is improved.

    本发明公开一种车用双电机驱动装置,包括第一电机和第二电机,第一电机的第一驱动轴左端与左半轴连接,右端设置第一连接齿轮,第二电机的第二驱动轴左端设置第二连接齿轮,还包括第三连接齿轮、第三驱动轴和同步器,第三连接齿轮设置于第三驱动轴,第三驱动轴与右半轴连接,同步器至少在第一工作位和第二工作位切换:第一工作位时,同步器连接第一连接齿轮和第三连接齿轮,二者同步转动;第二工作位时,同步器连接第二连接齿轮和第三连接齿轮,二者同步转动。本发明还提供一种车辆。本发明能够实现单电机、双电机动力切换,提高系统效率。
