The invention provides a two-gear bridge driving system for a vehicle and the vehicle adopting the two-gear bridge driving system. The transmission of the two-speed bridge drive system comprises a dual clutch and a planetary gear mechanism, by means of which torque from the electric machine can be selectively transmitted to the differential via a sun gear or a planet carrier of the planetary gear mechanism. Therefore, the two-gear bridge driving system is relatively simple in structure, and the phenomenon of power interruption in the gear shifting process can be avoided.
本发明提供了一种车辆用两挡电桥驱动系统及采用该两挡电桥驱动系统的车辆。该两挡电桥驱动系统的变速器包括双离合器和一个行星齿轮机构,借助于双离合器使得来自电机的扭矩能够选择性地经由行星齿轮机构的太阳轮或行星轮架传递到差速器。因此,根据本发明的两挡电桥驱动系统不仅结构相对简单而且能够实现在换挡过程中无动力中断现象。
