The invention relates to the technical field of engineering machinery, in particular to a brake system for an engineering vehicle and a mining dump truck. According to the brake system for the engineering vehicle, two oil inlets of a first manual-automatic switching valve are respectively communicated with a first electric proportional brake valve and a first pedal valve, and two oil inlets of a second manual-automatic switching valve are respectively communicated with a second electric proportional brake valve and a second pedal valve; in this way, the first manual-automatic switching valve can selectively communicate the first brake oil port A1 with the first electric proportional brake valve or the first pedal valve according to the vehicle driving state, and the second manual-automatic switching valve can selectively communicate the second brake oil port A2 with the second electric proportional brake valve or the second pedal valve according to the vehicle driving state. In this way, the braking purpose during manual driving or automatic driving of the vehicle can be achieved. Therefore, the driving safety and reliability are improved. And meanwhile, the priority of manual brake operation is also improved.
本发明涉及工程机械技术领域,尤其涉及一种工程车辆用制动系统及矿用自卸车。工程车辆用制动系统由于第一手自切换阀的两个进油口分别与第一电比例制动阀以及第一踏板阀连通,第二手自切换阀的两个进油口分别与第二电比例制动阀以及第二踏板阀连通,这样第一手自切换阀可根据车辆驾驶状态将第一制动油口A1选择性与第一电比例制动阀或第一踏板阀连通,第二手自切换阀可根据车辆驾驶状态将第二制动油口A2选择性与第二电比例制动阀或第二踏板阀连通,如此可实现车辆人工驾驶或自动驾驶时的制动目的。进而提高驾驶的安全可靠性。同时还提高了有人操作制动的优先级。
