The invention provides a bridge driving system which comprises a plurality of motors, two output half shafts and a center shaft, a first transmission mechanism is arranged between each motor and the center shaft, and a second transmission mechanism is arranged between the center shaft and a differential mechanism. Each first transmission mechanism is provided with a first intermediate shaft, a first gear shifting device, a first gear transmission unit and a second gear transmission unit, and the first gear shifting device can be selectively in transmission connection with the central shaft through the first gear transmission unit or the second gear transmission unit; the second transmission mechanism is provided with a second gear shifting device, one side of the second gear shifting device is in transmission connection with the differential mechanism through a third gear transmission unit, and the other side of the second gear shifting device is in transmission connection with the differential mechanism through a fourth gear transmission unit or is directly in transmission connection with the differential mechanism. According to the electric bridge driving system, gears can be conveniently adjusted, different torques can be output, and the reliability of the electric bridge driving system in use can be improved.

    本发明提供了一种电桥驱动系统,包括多个电机、两个输出半轴,以及中心轴,各电机与中心轴之间分别设有第一传动机构,中心轴与差速器之间设有第二传动机构;各第一传动机构均具有与第一中间轴、第一换挡装置,以及第一齿轮传动单元和第二齿轮传动单元,且第一换挡装置能够择一地通过第一齿轮传动单元或第二齿轮传动单元与中心轴传动相连;第二传动机构具有第二换挡装置,第二换挡装置的一侧通过第三齿轮传动单元和差速器传动相连,第二换挡装置的另一侧通过第四齿轮传动单元和差速器传动相连,或直接与差速器传动相连。本发明所述的电桥驱动系统,便于对挡位进行调节,而输出不同扭矩,还利于提高电桥驱动系统在使用中的可靠性。
