The invention discloses a preferential steering double-loop braking quantitative open-type system of a mine vehicle, and relates to the technical field of associated equipment of underground coal mines. The system comprises a gear pump, a safety valve set, a preferential valve, a steering gear, a steering oil cylinder assembly, a prefill valve, a main manifold block, an energy accumulator assembly, a double-line braking valve, a running braker assembly, a control valve, a lifting oil cylinder assembly, an oil return filter, an oil suction filter and a hydraulic oil tank. The preferential steering double-loop braking quantitative open-type system is simple in structure, and the number of applied elements and components is small; and by means of reasonable connection of all connectors of theabove components, preferential steering and double-loop braking of underground trackless auxiliary transportation equipment can be achieved well.

    本发明公开一种矿用车辆优先转向双回路制动定量开式系统,涉及煤矿井下相关设备技术领域,包括包括齿轮泵、安全阀组、优先阀、转向器、转向油缸组件、充液阀、主油路块、蓄能器组件、双路制动阀、行车制动器组件、控制阀、举升油缸组件、回油过滤器、吸油过滤器和液压油箱。本发明结构简单,元部件应用少,通过将前述部件的各个接口合理的连接,能够很好地实现井下无轨辅助运输设备优先转向、双回路制动。
