The embodiment of the invention relates to a high-speed switch valve active railway vehicle braking system which comprises a hydraulic valve block assembly, an energy accumulator and an oil tank, andthe hydraulic valve block assembly is communicated with the energy accumulator and the oil tank; the hydraulic valve block assembly comprises a hydraulic pump, a motor, a one-way valve, an overflow valve, a first high-speed switch valve, a second high-speed switch valve, a third high-speed switch valve, a fourth high-speed switch valve, a first brake pressure output interface, a second brake pressure output interface, a first electromagnetic reversing valve and a second electromagnetic reversing valve. Two paths of brake pressure output are adopted, accurate control over the brake pressure ofthe two paths of brake cylinders can be met, and the functions of service brake, parking brake, emergency brake, remote release and the like of a vehicle can be achieved.
本发明实施例涉及一种高速开关阀主动式轨道车辆制动系统,包括:液压阀块组成、蓄能器和油箱,所述液压阀块组成分别与所述蓄能器、所述油箱连通;其中,所述液压阀块组成包括液压泵、电机、单向阀、溢流阀、第一高速开关阀、第二高速开关阀、第三高速开关阀、第四高速开关阀、第一制动压力输出接口、第二制动压力输出接口、第一电磁换向阀和第二电磁换向阀。本发明采用两路制动压力输出,可满足对两路制动缸的制动压力的精确控制,可实现车辆的常用制动、停放制动、紧急制动、远程缓解等功能。
