The invention discloses a dumper braking system and a dumper braking method. According to the dumper braking system, an oil inlet P1 of a front wheel mechanical brake valve, an oil inlet P2 of a rear wheel mechanical brake valve and an oil inlet P3 of an electric auxiliary brake valve are all communicated with an oil pump. An oil return opening T1 of the front wheel mechanical brake valve, an oil return opening T2 of the rear wheel mechanical brake valve and an oil return opening T3 of the electric auxiliary brake valve are all communicated with the oil tank. And an oil outlet A2 of the rear wheel mechanical brake valve is communicated with a hydraulic input end of the rear wheel brake. The electric brake pedal, the rear wheel driving motor, the control switch and the electric auxiliary brake valve are all electrically connected with the controller. The controller applies current to the electric auxiliary brake valve according to the on-off state of the control switch and the rotation angle of the electric brake pedal. An oil outlet A1 of the front wheel mechanical brake valve and an oil outlet A3 of the electric auxiliary brake valve are both communicated with the hydraulic input end of the front wheel brake. The brake precision is high, the brake performance is good, and the service life of the front wheel brake and the rear wheel brake can be prolonged.

    本发明公开了自卸车制动系统及自卸车制动方法。该自卸车制动系统,前轮机械制动阀的进油口P1、后轮机械制动阀的进油口P2和电辅助制动阀的进油口P3均与油泵连通。前轮机械制动阀的回油口T1、后轮机械制动阀的回油口T2和电辅助制动阀的回油口T3均与油箱连通。后轮机械制动阀的出油口A2与后轮制动器的液压输入端连通。电制动踏板、后轮驱动电机、控制开关和电辅助制动阀均与控制器电连接。控制器依据控制开关的启闭状态和电制动踏板的旋转角度向电辅助制动阀施加电流。前轮机械制动阀的出油口A1和电辅助制动阀的出油口A3均与前轮制动器的液压输入端连通。制动精度高、制动性能好,且能提升前轮制动器和后轮制动器的使用寿命。
