The invention provides a two-gear variable-speed electric bridge driving system which comprises two clutches and a plurality of gears; a first gear (G1) is arranged on a motor shaft, a second gear (G2), a fourth gear (G4) and a first clutch (C1) are arranged on a first shaft (S1), a third gear (G3), a fifth gear (G5), a sixth gear (G6) and a second clutch (C2) are arranged on a second shaft (S2), and a seventh gear (G7) is connected with a shell of a differential mechanism; the first gear is meshed with the second gear, the second gear is meshed with the third gear, the fourth gear is meshed with the fifth gear, the sixth gear is meshed with the seventh gear, the first clutch (C1) controls connection between the second gear (G2) and the first shaft (S1), and the second clutch (C2) controls connection between the third gear (G3) and the second shaft (S2). According to the electric bridge driving system disclosed by the invention, three-stage gear transmission is used under two gears, so that a relatively large transmission ratio can be obtained, and the rotating direction of the motor does not need to be changed during gear switching.

    本发明提供一种两挡变速的电桥驱动系统,其包括两个离合器和多个齿轮,第一齿轮(G1)设置于电机轴,第二齿轮(G2)、第四齿轮(G4)和第一离合器(C1)设置于第一轴(S1),第三齿轮(G3)、第五齿轮(G5)、第六齿轮(G6)和第二离合器(C2)设置于第二轴(S2),第七齿轮(G7)连接差速器的壳体,第一齿轮与第二齿轮啮合,第二齿轮与第三齿轮啮合,第四齿轮与第五齿轮啮合,第六齿轮与第七齿轮啮合,第一离合器(C1)控制第二齿轮(G2)与第一轴(S1)的连接,第二离合器(C2)控制第三齿轮(G3)与第二轴(S2)的连接。根据本发明的电桥驱动系统在两个挡位下均使用三级齿轮传动,能获得较大的传动比且在挡位切换时不需要改变电机转动方向。
