The invention discloses a hydraulic auxiliary braking system of a vehicle. The system comprises an axle, a transmission shaft, a speed reducer, a clutch, a hydraulic pump, a hydraulic oil tank and a control valve, the axle is of a hollow structure, a shell of the speed reducer is fixedly connected to the axle, the transmission shaft is arranged in the axle, and one end of the transmission shaft extends to the end of the axle; the clutch is connected between the other end of the transmission shaft and the input end of the speed reducer, and used for connecting or disconnecting the other end of the transmission shaft and the input end of the speed reducer, and a main shaft of the hydraulic pump is connected to the output end of the speed reducer; and an oil inlet of the hydraulic pump is communicated with the hydraulic oil tank, an oil outlet of the hydraulic oil pump is communicated with an inlet of the control valve, and an outlet of the control valve is communicated with the hydraulic oil tank to form a hydraulic loop. According to the system, the impact force generated by a non-driving axle to a vehicle during braking is reduced, the braking distance is shortened, the braking performance of the vehicle is improved, the loss of friction plates is reduced, and a protection effect on a brake pad of a vehicle braking system is achieved.

    车辆的液压辅助制动系统,包括车桥、传动轴、减速器、离合器、液压泵、液压油箱以及控制阀,所述车桥为中空结构,减速器的外壳固定连接在车桥上,传动轴置于车桥内部,其一端延伸至车桥的端部;离合器联接在传动轴的另一端与减速器的输入端之间,用以使传动轴的该另一端与减速器的输入端联接或断开,液压泵的主轴联接在减速器的输出端;液压泵的进油口与液压油箱连通、液压油泵的排油口与控制阀的进口连通、控制阀的出口与液压油箱连通以构成一个液压回路。本发明减小了非驱动车桥在制动时对车辆产生的冲击力,缩短制动距离,提高了车辆的制动性能,减轻摩擦片的损耗,对车辆制动系统的刹车片起到保护作用。
