The invention relates to an automatic brake device for folding an undercarriage, and belongs to the field of design of aircraft hydraulic systems. The device comprises an automatic brake actuating cylinder, a rib plate, a spring, a base, a rocker arm and an emergency brake pressure reducing valve, the rib plate is fixed on the automatic brake actuating cylinder; one end of the spring is connected with the rib plate; the other end of the spring is connected with the rocker arm; the base is connected with the rocker arm; and the emergency brake pressure reducing valve is positioned below the automatic brake actuating cylinder. By means of the automatic braking device, the rotating airplane wheel can be braked in the retracting process of the airplane wheel, meanwhile, the automatic braking pressure is removed after the airplane wheel cabin door is retracted in place and an undercarriage retracting and releasing switch is closed to be neutral, and the safety of an airplane is guaranteed.
本发明涉及一种起落架收上自动刹车装置,属于飞机液压系统设计领域。该装置包括自动刹车作动筒、肋板、弹簧、底座、摇臂和应急刹车减压阀;所述肋板固定在自动刹车作动筒上;所述弹簧的一端连接肋板,弹簧的另一端连接摇臂;所述底座与摇臂连接;所述应急刹车减压阀位于自动刹车作动筒的下方。通过使用本发明中的自动刹车装置,可以实现机轮在收上过程中将转动的机轮刹停,同时在轮舱门收上到位起落架收放开关回中立后卸除自动刹车压力,保证飞机安全。
