The invention relates to a device for achieving a pressure maintaining parking function through a hydraulic braking system and a ball valve. The device for achieving the pressure maintaining parking function through the hydraulic braking system and the ball valve comprises a hydraulic braking system, an one-way valve, a pressure-maintaining ball valve, a motor or an electromagnetic actuator, a pressure-maintaining parking control unit, a hydraulic pressure sensor and a wheel cylinder, the braking function of an original hydraulic braking system is reserved, and the device further has the pressure-maintaining parking function. Compared with the prior art, the one-way valve, the pressure maintaining ball valve, the motor or the electromagnetic actuator and the hydraulic pressure sensor are additionally arranged on an original hydraulic braking system, the pressure maintaining parking function can be achieved, an extra parking braking system is omitted, cost is reduced, space is saved, and installation is convenient.

    本发明涉及一种利用液压制动系统和球阀实现保压驻车功能的装置,所述的利用液压制动系统和球阀实现保压驻车功能的装置包括液压制动系统、单向阀、保压球阀、电机或电磁作动器、保压驻车控制单元、液压力传感器、轮缸,保留了原液压制动系统的制动功能,还具有保压驻车功能。与现有技术相比,本发明在原液压制动系统上增加一个单向阀、一个保压球阀、一个电机或电磁作动器和一个液压力传感器就能够实现保压驻车功能,省去了额外的驻车制动系统,降低成本,节省空间,安装方便。
