The invention discloses a vehicle hydraulic braking device with a mechanical backup braking function and application. The device comprises a hydraulic braking unit and a mechanical backup braking unit. The hydraulic brake unit comprises a brake piston and a brake block which are arranged in a brake shell; a hydraulic cavity between the brake piston and the brake piston cylinder is connected with a hydraulic oil way control unit and drives the brake piston and the brake block through hydraulic pressure. The mechanical backup braking unit comprises an energy storage spring, a backup braking piston rod and an unloading unit which are arranged in a backup braking shell; an energy storage hydraulic cavity is formed between the backup brake piston rod and the brake shell and connected with an energy storage oil way. The energy storage hydraulic cavity is connected with the unloading unit, and hydraulic oil in the energy storage hydraulic cavity is discharged through the unloading unit; and the rod part of the backup brake piston can be introduced into the hydraulic cavity of the brake shell to drive the brake piston and the brake block. According to the device, when a hydraulic braking oil way breaks down, the reliability and safety of braking can be improved by braking wheels through the mechanical backup braking unit.

    本发明公开了一种带机械备份制动的车辆液压制动装置及应用,装置包括液压制动单元和机械备份制动单元;液压制动单元包括制动壳体内的制动活塞以及制动块;制动活塞与制动活塞缸之间的液压腔与液压油路控制单元连接通过液压驱动制动活塞及制动块;机械备份制动单元包括设于备份制动壳体内的蓄能弹簧和备份制动活塞杆及卸荷单元;备份制动活塞杆与制动壳体之间为蓄能液压腔,蓄能液压腔与蓄能油道连接;蓄能液压腔与卸荷单元连接,通过卸荷单元排出蓄能液压腔中的液压油;备份制动活塞的杆部可传入制动壳体液压腔中驱动制动活塞及制动块。本装置可在液压制动油路故障时,通过机械备份制动单元对车轮的制动,提高制动的可靠性和安全性。
