The invention relates to a bridge drive system for a vehicle, comprising a parking lock comprising a housing (5), an actuator, a disk (12), a restoring part (9) and a multi-way valve (3), the actuator being arranged in the housing (5) and having a locking portion (71), the disk (12) being arranged in the housing (5), the restoring part (9) being arranged in the housing (5), the restoring part (9) being arranged in the housing (5), and the multi-way valve (3) being arranged in the housing (5). The disc part (12) is arranged in a rotationally fixed manner on a transmission shaft (13) of the bridge drive system and is configured with a counter-locking part (121), the multi-way valve (3) is configured to be switchable between a first valve position, a second valve position and a third valve position, and when the multi-way valve (3) is in the first valve position, the counter-locking part (121) is in the second valve position, and when the multi-way valve (3) is in the third valve position, the counter-locking part (121) is in the third valve position. The fluid (6) can be supplied from the fluid source (1) to a hydraulic chamber formed by the housing (5) and the actuator via the multi-way valve (3) to drive the actuator to move axially against the action of the reset member (9) such that the locking portion (71) engages the mating locking portion (121) to achieve rotational locking of the disk (12), the fluid (6) can be discharged from the hydraulic chamber via the multi-way valve (3) when the multi-way valve (3) is in the second valve position, and the fluid (6) can be discharged from the hydraulic chamber via the multi-way valve (3) when the multi-way valve (3) is in the second valve position. And when the multi-way valve (3) is located at the third valve position, the multi-way valve (3) blocks communication between the fluid source (1) and the hydraulic cavity.

    本发明涉及一种用于车辆的电桥驱动系统,电桥驱动系统包括驻车锁止器,驻车锁止器包括壳体(5)、执行件、盘件(12)、复位件(9)和多通阀(3),其中,执行件布置在壳体(5)内并且构造有锁定部(71),盘件(12)抗旋转地布置在电桥驱动系统的传动轴(13)上并且构造有配对锁定部(121),多通阀(3)被配置为能够在第一阀位、第二阀位和第三阀位之间进行切换,其中,在多通阀(3)处于第一阀位时,流体(6)能够从流体源(1)经由多通阀(3)供给至由壳体(5)和执行件形成的液压腔以驱动执行件克服复位件(9)的作用轴向移动,使得锁定部(71)与配对锁定部(121)接合,从而实现盘件(12)的旋转锁定,在多通阀(3)处于第二阀位时,流体(6)能够经由多通阀(3)从液压腔中排出,从而执行件能够在复位件(9)的作用下复位以解除盘件(12)的旋转锁定,在多通阀(3)处于第三阀位时,多通阀(3)阻隔流体源(1)和液压腔的连通。
