A brake device of a dump truck comprises a parking brake, a parking hydraulic cylinder, a first energy accumulator, a front axle brake, a rear axle brake, a second energy accumulator, a third energy accumulator, a two-way brake valve and a second hand-operated direction valve. A first oil inlet P1 of the second hand-operated direction valve is communicated with the first energy accumulator, a second oil inlet P2 of the second hand-operated direction valve is communicated with an execution port A2 of the two-way brake valve, an execution port B of the second hand-operated direction valve is communicated with the rear axle brake, and an execution port A of the second hand-operated direction valve is communicated with a rod cavity of the parking hydraulic cylinder; and an oil return port T ofthe second hand-operated direction valve is communicated with the oil tank. The brake device is simple in structure, and loading braking can be automatically carried out during parking braking.

    一种自卸车的制动装置,包括停车制动器、停车液压缸、第一蓄能器、前桥制动器、后桥制动器、第二蓄能器、第三蓄能器、双路制动阀和第二手动换向阀;所述第二手动换向阀的第一进油口P1与第一蓄能器连通,第二手动换向阀的第二进油口P2与双路制动阀的执行口A2口连通,第二手动换向阀的执行口B与后桥制动器连通,第二手动换向阀的执行口A与停车液压缸的有杆腔连通,第二手动换向阀的回油口T与油箱连通。本发明结构简单,可实现进行停车制动时自动进行装载制动。
