The invention relates to a brake device, and discloses a hydraulic brake system and an engineering vehicle, the hydraulic brake system comprises an oil inlet path and two brake paths, and the oil inlet path is sequentially provided with a prefill valve and an energy storage device; the brake oil way comprises a manual brake oil way provided with a mechanical brake valve and an electric control brake oil way provided with a traveling electric control brake valve, one end of the manual brake oil way and one end of the electric control brake oil way are both connected with the oil inlet oil way, and the other end of the manual brake oil way is connected with a brake through a shuttle valve. And the other end of the electric control brake oil way is connected with the brake through the shuttle valve, so that the manual brake oil way or the electric control brake oil way is selectively communicated with the brake through the shuttle valve. The braking function during manual operation can be achieved, the automatic braking function during unmanned driving can also be achieved, the braking synchronism of two paths can be guaranteed, and the dangers such as rollover caused by failure of one side when the left braking and the right braking are independent are avoided.
本发明涉及制动装置,公开了一种液压制动系统及工程车辆,该液压制动系统包括进油油路和两路制动油路,所述进油油路上依次设置有充液阀和蓄能装置,所述制动油路包括设置有机械制动阀的人工制动油路和设置有行车电控制动阀的电控制动油路,所述人工制动油路一端和所述电控制动油路一端均与所述进油油路连接,所述人工制动油路另一端通过梭阀与制动器连接,所述电控制动油路另一端通过所述梭阀与所述制动器连接,以通过所述梭阀选择性地使所述人工制动油路或所述电控制动油路与所述制动器连通。既可以实现人工操纵时的制动功能,也可以实现无人驾驶时自动制动功能,可保证两路制动同步性,避免左右两边制动独立时因一侧失效发生侧翻等危险。
