The invention belongs to the technical field of aviation machinery, and particularly relates to an airplane wheel brake control valve group and an airplane brake system provided with the airplane wheel brake control valve group. Switching of an emergency braking module and a shutdown braking module is achieved by controlling the electromagnetic valve, shutdown braking and emergency braking share two pressure output channels, reversing is achieved through the selector valve, two operation tasks of emergency braking and shutdown braking can be completed through a single set of brake valve, an electro-hydraulic pressure servo valve is replaced by a rotary direct-drive servo valve set, and the operation efficiency is improved. The internal leakage is reduced; the device has the characteristics of high integration level, compact appearance, small volume, light weight and high reliability. The method is suitable for being popularized and used in aircraft manufacturing.
本发明属于航空机械技术领域,具体涉及一种机轮制动控制阀组及配置有该机轮制动控制阀组的飞机刹车系统。通过控制电磁阀实现应急刹车和停机刹车模块的切换,停机刹车和应急刹车共用两个压力输出通道,通过选择阀实现换向,单套刹车阀即可完成应急刹车和停机刹车两种操作任务,通过选用旋转直驱伺服阀组替代电液压力伺服阀,减少了内泄漏;具有集成度高、外形紧凑、体积小、重量轻、可靠性高的特点。适于在飞机制造中推广使用。
