The invention provides a two-gear bridge driving system and a vehicle, a transmission of the two-gear bridge driving system adopts two independent intermediate shafts parallel to an input shaft of the transmission, and the two intermediate shafts are respectively provided with an intermediate gear which is always meshed with an input gear of the input shaft; and two clutches are utilized to enable the intermediate gears to be selectively connected with or disconnected from the corresponding intermediate shafts in a torsion-resistant manner. As a result, the two-speed bridge drive system according to the invention also allows torque to be selectively transmitted from two different torque transmission paths, and the axial dimension of the transmission is reduced compared to the transmission of the two-speed bridge drive system described in the background art.

    本发明提供了一种两挡电桥驱动系统及车辆,该两挡电桥驱动系统的变速器采用与变速器输入轴平行的两根独立的中间轴,两根中间轴分别设置有与输入轴的一个输入齿轮始终啮合的中间齿轮,并利用两个离合器使得中间齿轮与对应的中间轴选择性地以抗扭的方式联接或解除这种联接。由此,根据本发明的两挡电桥驱动系统同样能够实现选择性地从两条不同的扭矩传递路径传递扭矩,并且与背景技术中说明的两挡电桥驱动系统的变速器相比减小了变速器的轴向尺寸。
