The invention relates to a service brake emergency rescue device for a hydraulic brake vehicle model. The service brake emergency rescue device comprises a brake pedal, a brake master cylinder, a hydraulic controller and wheel brakes. The device is characterized in that: the brake master cylinder is connected to the hydraulic controller through a first brake loop, a first hydraulic sensor and a first execution valve; the brake master cylinder is connected to the hydraulic controller through a second brake loop, a second hydraulic sensor and a second execution valve; and an instrument for displaying the internal pressure condition of the double loops and a control panel for controlling the on-off of the first execution valve and the second execution valve are arranged in a cab. According tothe invention, a failed loop is temporarily interrupted through the execution valve, so that an increased idle stroke of the brake pedal is eliminated, and the residual brake loop is subjected to pressure buildup more controllably, so that the residual brake performance is fully utilized.

    本发明涉及一种液刹制动车型的行车制动紧急救援装置,包括制动踏板、制动主缸、液压控制器和车轮制动器;特征在于,所述制动主缸经由第一制动回路、第一液压传感器和第一执行阀与液压控制器相连;所述制动主缸经由第二制动回路、第二液压传感器和第二执行阀与液压控制器相连;驾驶室内设有用于显示双回路内部压力情况的仪表以及用于控制第一执行阀和第二执行阀通断的操纵板。本发明通过执行阀将失效的一个回路暂时中断,以消除制动踏板增加的空行程,更可控的对剩余的制动回路进行建压,以充分的利用剩余的制动性能。
