The invention provides a two-gear bridge driving system and a vehicle. A transmission of the two-gear bridge driving system comprises a triple planetary gear mechanism, a first clutch and a second clutch, the first clutch and the second clutch are independent of each other, and the triple planetary gear mechanism only comprises a sun gear and three groups of planetary gears fixed to one other. Thesun gear is always engaged with one group of planet gears, the other two groups of planet gears are always engaged with one gear ring, and each gear ring is connected with a shell of the transmissionthrough the first clutch and the second clutch. Therefore, compared with the two-gear bridge driving system in the prior art, the two-gear bridge driving system is simpler in structure, lower in cost, and small in axial size and weight and can realize good NVH control.

    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包括三联行星齿轮机构以及彼此独立的第一离合器和第二离合器,该三联行星齿轮机构仅包括一个太阳轮以及彼此固定的三组行星轮,太阳轮与其中一组行星轮始终处于啮合状态,其余两组行星轮则分别与一个齿圈始终处于啮合状态,各齿圈经由第一离合器和第二离合器与变速器的壳体相连。因此,根据本发明的两挡电桥驱动系统与上述根据现有技术的两挡驱动电桥相比结构更简单、成本更低、轴向尺寸和重量都小,并且易于实现良好的NVH控制。
