The invention discloses an automobile brake system with an auxiliary hand brake device, which comprises a hand brake cable connecting assembly, a telescopic part is arranged in the opposite direction of a stay wire of the hand brake cable connecting assembly, a pressure medium inlet and outlet of the telescopic part is connected with a pressure medium source through an electromagnetic valve, and an electromagnetic coil of the electromagnetic valve is connected with a power supply through a switch. The switch is installed on the rear portion of the pedal braking vane, when the pedal braking vane is treaded to the bottom, the switch is closed, the electromagnetic valve coil is powered on, the telescopic component contracts to drive the hand brake handle to rotate, the ratchet wheel and pawl structure is synchronously self-locked, and automatic parking hand braking, loosening of the pedal braking vane, power loss of the electromagnetic valve coil and return of the electromagnetic valve are completed. And when the hand brake is manually released, the telescopic component is returned. Compared with the prior art, automatic hand braking can be achieved after the vehicle is parked by stepping on the brake pedal, and the vehicle is prevented from sliding on a ramp.

    本发明公开一种带辅助手刹装置的汽车刹车系统,包括手刹线连接组件,在手刹线连接组件的拉线反方向设置有伸缩部件,伸缩部件的压力介质进出口通过电磁阀与压力介质源连接,电磁阀的电磁线圈通过开关与电源连接,而开关安装在脚踏刹车板的后部,当脚踏刹车板被踩到底时,开关闭合,电磁阀线圈得电,伸缩部件收缩带动手刹把转动,棘轮棘爪结构同步自锁,完成驻车自动手刹,松开脚踏刹车板,电磁阀线圈失电,电磁阀回位,但此时由于棘轮棘爪的原因,伸缩部件无法回位,当手动松开手刹,伸缩部件回位。与现有技术相比,本发明能够在脚踩刹车踏板至车辆驻车后自动手刹避免车辆在坡道上溜车。
