The invention provides a two-gear bridge driving system and a vehicle. On one hand, according to the transmission of the two-gear bridge driving system, a first clutch and a second clutch which are independent of each other are adopted to replace a synchronizer to achieve a gear shifting function, and a part of structure such as a pinion shaft is omitted, so that the two-gear bridge driving systemis simple in structure, low in cost, small in axial size and high in reliability; on the other hand, in the two-gear bridge driving system, the first clutch is arranged between the gear ring of a planetary gear mechanism and the transmission shell, and the second clutch is arranged between the sun gear and the planet carrier of the planetary gear mechanism. Therefore, under the condition that gear shifting is achieved through the first clutch and the second clutch, the phenomenon of power interruption cannot be generated in the gear shifting process.

    本发明提供了一种两挡电桥驱动系统及车辆。一方面,根据本发明的两挡电桥驱动系统的变速器通过采用彼此独立的第一离合器和第二离合器代替同步器实现换挡功能并且省略了例如小齿轮轴的部分结构,使得该两挡电桥驱动系统结构简单、成本低、轴向尺寸小且可靠性高;另一方面,在根据本发明的两挡电桥驱动系统中,第一离合器设置于行星齿轮机构的齿圈与变速器壳体之间且第二离合器设置于行星齿轮机构的太阳轮和行星轮架之间,因此在通过第一离合器和第二离合器实现换挡的情况下不会在换挡过程中产生动力中断现象。
