The invention provides a hydraulic braking system of a highway-railway dual-purpose vehicle. The system comprises a hydraulic oil tank, an oil pump, a direction control valve assembly, a prefill valve, an energy accumulator, a foot brake valve, a front axle shuttle valve, a front axle brake cylinder and a rear axle brake cylinder. Multi-loop hydraulic braking modes, comprising three braking modesof service braking, emergency braking and parking braking, are adopted, hydraulic oil output by the oil pump can move towards different loops according to different braking modes, double-way braking is adopted under service braking, braking can be conducted under the condition that one way of hydraulic pressure loses efficacy, safety is guaranteed, and braking is more reliable.
本发明提供了一种包括液压油箱、油泵、方向控制阀组件、充液阀、蓄能器、脚制动阀、前桥梭阀、前桥制动分泵及后桥制动分泵。采用了多回路液压制动模式,包含常用制动、紧急制动、驻车制动三种制动模式,油泵输出的液压油能够根据不同的制动模式进行不同回路的走向,其在常用制动下,采用双路制动,可以实现在一路液压失效的情况下还可以进行制动,保证了安全,制动更可靠。
