The invention relates to a discrete hydraulic valve airplane wheel brake control system which comprises a control system. The digital brake valve group comprises a pressure boosting valve group, and the pressure boosting valve group comprises at least one pressure boosting switch valve; the pressure reducing valve group comprises at least one first pressure reducing switch valve; when the airplane wheels are controlled to be braked, the control system sends out an instruction to control the booster valve set to act, the oil pressure in the airplane wheel actuator is increased, and therefore airplane wheel braking is achieved; when the airplane wheel is controlled to be loosened, the control system sends out an instruction to control the pressure reducing valve set to act, the oil pressure in the airplane wheel actuator is reduced, and airplane wheel loosening is achieved. Instructions can be sent for the pressure boosting valve set and the pressure reducing valve set, the opening number and time of the switch valves are controlled, then the airplane wheel is controlled to achieve braking and brake loosening, control over airplane wheel braking can be achieved through a simple structure, the requirement for the cleanliness of hydraulic oil is lowered through the switch valves, and the reliability of the airplane wheel is improved. And the pollution resistance is high, so that the use cost is reduced.
本发明涉及一种离散液压阀机轮刹车控制系统,包括控制系统;数字刹车阀组,数字刹车阀组包括:升压阀组,升压阀组包括至少一个升压开关阀;和降压阀组,降压阀组包括至少一个第一降压开关阀;其中,当控制机轮刹车时,控制系统发出指令控制升压阀组动作,机轮作动器内的油压升高,以实现机轮刹车;当控制机轮松刹时,控制系统发出指令控制降压阀组动作,机轮作动器内的油压降低,以实现机轮松刹。本发明可以针对升压阀组和降压阀组发出指令,控制开关阀开启的数量以及时间,进而控制机轮实现刹车和松刹,采用简单的结构就可以实现对机轮刹车的控制,采用开关阀降低对液压油的清洁度的要求,耐污染能力较强从而降低使用成本。
