The invention discloses a hydrostatic driving vehicle walking brake system, a brake valve and a brake method, which are applied to the output end of a brake pump, the hydrostatic driving vehicle walking brake system comprises a prefill valve and the brake valve, a pedal position signal of the brake valve is associated with a hydrostatic closed walking system, and braking is implemented by stages through the brake valve. Pressure oil output by the brake pump passes through the prefill valve and then outputs high pressure to the energy accumulator, output power of the energy accumulator is output to the brake valve, the output pressure is controlled to the service brake according to the angle proportion of stepping on the brake valve by a driver, the pressure is output in a three-section mode, in the first stage, the brake valve outputs no brake pressure, and in the second stage, the brake valve outputs no brake pressure. The position sensor outputs signals, and the vehicle is decelerated during driving; in the second stage, the brake valve outputs low pressure, and the driver feels like braking; and in the third stage, the brake valve rapidly builds pressure, and the requirements for emergency braking and braking distance are met.

    本发明公开了一种静液压驱动车辆行走制动系统、制动阀及制动方法,应用于制动泵输出端,包括充液阀和制动阀,所述制动阀的踏板位置信号与静液压闭式行走系统关联,通过所述制动阀分阶段实施制动,所述制动泵输出的压力油经过所述充液阀后输出高压到蓄能器,所述蓄能器的输出动力到所述制动阀,通过驾驶员的踩踏所述制动阀角度比例控制输出压力到行车制动器,压力分三段式输出,在第一阶段中,制动阀无制动压力输出,位置传感器有信号输出,车辆行车减速;在第二阶段中,制动阀低压输出,驾驶员有刹车的过程感觉;在第三阶段中,制动阀快速建立压力,满足紧急刹车和制动距离的要求。
