The invention discloses a dual-motor drive axle with a gear shifting structure, which is characterized in that a first motor is rigidly connected with an output shaft of the first motor, and a first power output unit and a second power output unit are arranged on the output shaft of the first motor; one side of the drive axle is connected with the first power output unit and the second power output unit. The other side of the drive axle is connected with a second speed change device, and the second motor is connected with the second speed change device. The first motor drives the first power output unit and the second power output unit to shift gears; the first power output unit and the second power output unit transmit power to a drive axle, and meanwhile, a second motor drives a second gearbox to assist running power when the running power of the vehicle is insufficient; the drive axle achieves coupling between power output by the first power output unit and the second power output unit and power output by the second speed change device, the power and torque redundancy of a single-motor system are reduced, and the economical efficiency and the dynamic property of the whole vehicle are improved.
本发明公开了一种带换挡结构的双电机驱动桥,包括:第一电机与第一电机输出轴刚性连接,第一动力输出单元与第二动力输出单元设置在第一电机输出轴上;驱动桥的一侧分别连接第一动力输出单元与第二动力输出单元;驱动桥的另一侧连接第二变速装置,第二电机与第二变速装置相连。本发明通过第一电机驱动第一动力输出单元和第二动力输出单元进行换挡;第一动力输出单元和第二动力输出单元将动力传递至驱动桥,同时第二电机驱动第二变速箱实现在车辆行驶动力不足时,对行驶动力进行辅助;驱动桥实现第一动力输出单元和第二动力输出单元输出的动力与第二变速装置输出的动力之间的耦合,降低单电机系统功率及转矩冗余,提高整车的经济性和动力性。
