The invention provides a two-gear variable-speed bridge driving system which comprises a motor (E), a motor shaft (Se), a double clutch (DC), a plurality of gears, a planetary gear set (PG) and a differential (D), the motor shaft (Se) is connected with a rotor of the motor (E) and a driving part of the double clutch (DC), a first driven disc (C1) of the double clutch (DC) is connected with one of the gears, and a second driven disc (C2) of the double clutch (DC) is connected with the other of the gears. A second driven disc (C2) of the dual clutch (DC) is connected to the other of the plurality of gears, one gear for transmitting torque through a first transmission path to a terminal gear of the plurality of gears and the other gear for transmitting torque through a second transmission path to the terminal gear, the sun gear (PG1) of the planetary gear set (PG) being connected to the terminal gear, and the sun gear (PG2) of the planetary gear set (PG) being connected to the sun gear (PG1) of the planetary gear set (PG). The planet carrier of the planetary gear set (PG) is connected to the shell of the differential (D). According to the two-gear speed change bridge driving system, the structure is compact, and the high transmission ratio can be achieved through the small size.

    本发明提供一种两挡变速的电桥驱动系统,其包括电机(E)、电机轴(Se)、双离合器(DC)、多个齿轮、行星齿轮组(PG)和差速器(D),电机轴(Se)连接电机(E)的转子和双离合器(DC)的主动部分,双离合器(DC)的第一从动盘(C1)连接多个齿轮中的一个齿轮,双离合器(DC)的第二从动盘(C2)连接多个齿轮中的另一个齿轮,一个齿轮用于将扭矩通过第一传动路径传递给多个齿轮中的终端齿轮,另一个齿轮用于将扭矩通过第二传动路径传递给终端齿轮,行星齿轮组(PG)的太阳轮(PG1)与终端齿轮连接,行星齿轮组(PG)的行星架与差速器(D)的壳体连接。根据本发明的两挡变速的电桥驱动系统结构紧凑、可以利用较小的尺寸实现较高的传动比。
