The invention belongs to the technical field of vehicle braking, and particularly relates to a brake-by-wire system and a wide-body mining dump truck, which comprise an air supply unit, a multi-loop protection valve, a braking execution unit, a pair of front axle braking air chambers, a plurality of pairs of middle and rear axle braking air chambers, a front axle braking loop, a front axle air cylinder, a single-channel EBS valve and a middle and rear axle braking loop, comprising a middle-rear axle air cylinder, a multi-channel EBS valve, a service brake valve and an electromagnetic relay valve. The electromagnetic relay valve is arranged, the air inlet is communicated with the middle and rear axle air storage cylinder, the first air outlet is communicated with the control port of the single-channel EBS valve, and the second air outlet is communicated with the control port of the multi-channel EBS valve, so that an air braking safety system and an electronic braking safety system are combined, and the automatic braking auxiliary function is achieved; the braking system can actively brake when encountering sudden dangerous situations or the distance between the braking system and a front vehicle and pedestrians is smaller than the safe distance, and therefore the performance and safety of the braking system are improved.
本发明属于车辆制动技术领域,具体涉及一种线控制动系统及宽体矿用自卸车,包括供气单元、多回路保护阀、制动执行单元,包括一对前桥制动气室和多对中后桥制动气室、前桥制动回路,包括前桥储气筒和单通道EBS阀、中后桥制动回路,包括中后桥储气筒和多通道EBS阀、行车制动阀以及电磁继动阀。本发明设置电磁继动阀,并使进气口与中后桥储气筒相连通,第一出气口与单通道EBS阀的控制口相连通,第二出气口与多通道EBS阀的控制口相连通,从而将气压制动和电子制动安全系统相结合,以此具有了自动刹车辅助功能,能够在遇到突发危险情况或与前车及行人距离小于安全距离时主动进行刹车,据此提高了制动系统的性能和安全性。
