Steering brake system and engineering machinery
The invention discloses a steering braking system and engineering machinery, and the steering braking system comprises a gear pump, a priority valve, a hydraulic cylinder, a hydraulic cylinder, a hydraulic cylinder and a hydraulic cylinder, and an oil outlet of the gear pump is connected with a P port of the priority valve; an EF port of the priority valve converges with the working system; a CF port of the priority valve is respectively connected with a P port of the steering gear and a P port of the signal control valve; an Ls port of the steering gear is connected with an Ls2 port of the signal control valve; an Ls port of the priority valve is connected with an Ls1 port of the signal control valve; a port A of the signal control valve and a port P of the brake valve are respectively connected with the energy accumulator; the steering gear is used for controlling the steering oil cylinder to steer; the signal control valve is used for controlling parking brake; the brake valve is used for controlling service braking. Working, steering and braking share an oil source, mutual interference of the two braking systems during simultaneous working is avoided by means of the intermittent working characteristic of the braking systems, and steering and braking performance is guaranteed.
本发明公开了一种转向制动系统及工程机械，转向制动系统包括：齿轮泵，所述齿轮泵的出油口与优先阀的P口连接；优先阀的EF口与工作系统合流；优先阀的CF口分别与转向器的P口、信号控制阀的P口连接；转向器的Ls口与信号控制阀的Ls2口连接；优先阀的Ls口与信号控制阀的Ls1口连接；信号控制阀的A口、制动阀的P口分别与蓄能器连接；转向器用于控制转向油缸实现转向；信号控制阀用于控制停车制动；制动阀用于控制行车制动。本发明实现工作、转向与制动共有油源，利用制动系统间歇式工作特点避免了两者在同时工作时的相互干扰，保证了转向及制动性能。
