The invention provides a two-gear variable-speed bridge driving system which comprises a double clutch (DC) and a planetary gear set (PG). A driving part of the double clutch (DC) is connected with a rotor of a motor (E) through a motor shaft (A1), a first driven disc (C1) is connected with an output shaft (A2), a second driven disc (C2) is connected with a sun gear of the planetary gear set (PG), the sun gear can be rotationally arranged on the periphery of the output shaft (A2) in a sleeving mode relative to the output shaft (A2), a gear ring of the planetary gear set (PG) is fixed to a shell of the gearbox, the planet carrier is connected with the first gear set driving wheel (G11), the first gear set driving wheel (G11) can be rotationally arranged on the periphery of the output shaft (A2) in a sleeving mode relative to the output shaft (A2), and the second gear set driving wheel (G21) is connected with the output shaft (A2). According to the two-gear variable-speed bridge driving system, transmission is stable in the gear shifting process, and a transmission system can be free of power interruption.

    本发明提供一种两挡变速的电桥驱动系统,其包括双离合器(DC)和行星齿轮组(PG),双离合器(DC)的主动部分通过电机轴(A1)与电机(E)的转子连接,第一从动盘(C1)与输出轴(A2)连接,第二从动盘(C2)与行星齿轮组(PG)的太阳轮连接,太阳轮能相对于输出轴(A2)转动地套设在输出轴(A2)的外周,行星齿轮组(PG)的齿圈固定于齿轮箱的壳体,行星架与第一齿轮组主动轮(G11)连接,第一齿轮组主动轮(G11)能相对输出轴(A2)转动地套设在输出轴(A2)的外周,第二齿轮组主动轮(G21)与输出轴(A2)连接。根据本发明的两挡变速的电桥驱动系统,换挡过程中传动平稳,传动系统可以没有动力中断。
