The invention relates to the field of tire type walking equipment, and discloses a load-sensitive hydraulic brake valve and a load-sensitive hydraulic system thereof, and the load-sensitive hydraulic system comprises the load-sensitive hydraulic brake valve, a load-sensitive pump, a priority valve, a steering hydraulic system, a working hydraulic system, a shuttle valve and corresponding connecting pipelines; a P port, an A port, a B port, a T port, an LS1 port, an LS port, a low-pressure alarm pressure switch and a brake lamp pressure switch are arranged outside the load-sensitive hydraulic brake valve. According to the system, full-hydraulic dynamic braking can be achieved on equipment without a prefill valve, the equipment efficiency is improved, the installation cost is reduced, the energy consumption is reduced, and the service life is prolonged. Wherein the load-sensitive hydraulic brake valve integrates a brake function, a pressure maintaining function, a high-low pressure switching function, a pressure signal selection function and a pressure alarm function; the invention has the advantages of fast braking response, low noise, low failure rate, high safety coefficient, compact structure, low cost, low energy consumption and long service life.

    本发明涉及轮胎式行走设备领域,公开了一种负载敏感液压制动阀及其负载敏感液压系统,该负载敏感液压系统包括负载敏感液压制动阀、负载敏感泵、优先阀、转向液压系统、工作液压系统、梭阀及相应连接管路;所述负载敏感液压制动阀外部具有P口、A口、B口、T口、LS1口、LS口、低压报警压力开关和制动灯压力开关。本发明系统不需要装备充液阀就能在设备上实现全液压动力制动,提高设备效率,降低装机成本,降低能耗、延长使用寿命。其中负载敏感液压制动阀集成制动功能、保压功能、高低压切换功能、压力信号选择功能及压力报警功能于一体;本发明制动响应快、噪音小、故障率低、安全系数高、结构紧凑、成本低、能耗低、使用寿命长。
