An unmanned braking hydraulic system of an electric transmission dumper comprises a service brake, the service brake is connected with a braking relay valve and a logic shuttle valve, the logic shuttle valve is connected with a braking electro-hydraulic proportional valve and a pilot two-way full-hydraulic pedal valve, and the service brake and the braking relay valve are provided with pressure sensors. Each pressure sensor is connected with an electric controller and a cab display, the electric controller is connected with the braking electro-hydraulic proportional valve, and the system further comprises a braking energy accumulator, an emergency braking valve, a loading braking valve, an automatic braking applying valve and a hydraulic oil tank. The brake performance is monitored and adjusted in real time through the hydraulic sensor, closed loop control and remote brake control are achieved, the brake response is fast, hydraulic brake is automatically applied when a vehicle is in an active power failure or abnormal power failure condition, the operation safety of equipment is guaranteed to a great extent, free switching between a manual driving braking mode and an unmanned driving braking mode can be achieved, flexibility and changeability are achieved, and controllability is high.

    一种电传动自卸车无人驾驶制动液压系统,包括行车制动器,行车制动器连接有制动继动阀和逻辑梭阀,逻辑梭阀连接有制动电液比例阀和先导双路全液压踏板阀,行车制动器和制动继动阀设有压力传感器,压力传感器连接有电控制器和驾驶室显示器,电控制器与制动电液比例阀连接在一起,还包括制动蓄能器、紧急制动阀、装载制动阀、制动自动施加阀和液压油箱。本发明通过液压传感器实时监测并调节制动性能,实现控制闭环和远程操控制动,制动响应快,当车辆处于主动断电或异常断电情况时,自动施加液压制动,极大程度的保证了设备的运行安全性,可在人工驾驶制动模式与无人驾驶制动模式间自由切换,灵活多变,可操控性强。
