The invention provides a two-gear bridge driving system and a vehicle. A transmission of the two-gear bridge driving system comprises a duplicate planetary gear mechanism, the duplicate planetary gearmechanism only comprises one sun gear, the sun gear is fixed relative to an input gear of the transmission, and the sun gear is always engaged with one planetary gear in the duplicate gear. Therefore, compared with a two-gear bridge driving system in the prior art, the two-gear bridge driving system is simpler in structure, low in cost and light in weight, and good NVH control is easy to achieve.

    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双联行星齿轮机构,该双联行星齿轮机构仅包括一个太阳轮,该太阳轮与变速器输入齿轮相对固定,并且该太阳轮与双联齿轮中的一个行星轮始终处于啮合状态。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电桥驱动系统相比结构更简单、成本低、重量小,并且易于实现良好的NVH控制。
