The invention discloses a hydraulic braking system, a hydraulic braking system control method and an engineering vehicle, the hydraulic braking system comprises a hydraulic pump, a prefill valve, a brake valve and a brake oil cylinder of a brake, an oil inlet of the hydraulic pump is communicated with an oil tank, and an oil outlet of the hydraulic pump is communicated with an oil inlet of the prefill valve; one oil outlet of the prefill valve is communicated with an oil inlet of the brake valve, one oil outlet of the brake valve is communicated with the brake oil cylinder, the hydraulic brake system further comprises a proportional control throttle valve and a brake clearance adjusting device, and the proportional control throttle valve is arranged on a pipeline between the brake valve and the brake oil cylinder; the brake clearance adjusting device can adjust the clearance between a brake shoe and a brake drum of the brake. According to the hydraulic braking system, by adjusting the proportional control throttle valve and the brake clearance adjusting device, the negative effects that braking is too sensitive, and the comfort of an operator is poor when a whole vehicle is braked can be achieved.

    本发明公开了液压制动系统、液压制动系统控制方法及工程车辆,该液压制动系统包括:液压泵、充液阀、制动阀和制动器的制动油缸,液压泵的进油口与油箱连通,液压泵的出油口与充液阀的进油口连通,充液阀的其一出油口与制动阀的进油口连通,制动阀的其一出油口与制动油缸连通,该液压制动系统还包括比例控制节流阀和制动间隙调节装置,比例控制节流阀设置于制动阀与制动油缸之间的管路上;制动间隙调节装置能调节制动器的制动蹄与制动鼓之间的间隙。该液压制动系统,通过调节比例控制节流阀以及制动间隙调节装置,能解决整车制动时会体现出刹车过灵敏、操作者舒适感差等负面效果。
