Embodiment Construction

[0048] In this embodiment, on the basis of the braking system of the prior art, a hydraulic switch is added on the basis of the approaching brake wheel braking device to form an aircraft braking system with an air residual pressure alarm function.

[0049] This embodiment includes a brake command sensor 1, an anti-skid brake control box 2, a wheel speed sensor 3, an electro-hydraulic pressure servo valve 4, an electromagnetic hydraulic lock 5, a hydraulic switch 7, a landing switch, an automatic circuit protection switch 12, and a +28V power supply 13 , hydraulic source 8 and oil tank 9, wherein said landing switch is divided into left landing gear landing switch 10 and right landing gear landing switch 11.

[0050] The positive pole of the +28VDC power supply 13 is connected with the positive pole of the automatic circuit protection switch 12, the negative pole of the automatic circuit protection switch 12 is connected with the power input terminal of the right landing gear la...

Abstract

The invention provides an aircraft brake system with an air over-pressure alarming function and a control method. The aircraft brake system with the air over-pressure alarming function comprises a hydraulic switch; a state signal output port of the hydraulic switch communicates with an input end of a pressure collection interface of an anti-skid braking control box; and a hydraulic pressure collection port communicates with a hydraulic pipeline of a working oil port of a brake device. A working oil port of an electro-hydraulic pressure servo valve is accessed into a hydraulic pipeline. A powersupply input end of a right landing gear ground switch communicates with a cathode of a circuit protection automatic switch; and a power supply output end of the right landing gear ground switch communicates with a power supply input end of a left landing gear ground switch. A power supply output end of the left landing gear ground switch communicates with a signal collection interface of a sliding brake control box ground switch. According to the aircraft brake system with the air over-pressure alarming function, by using the hydraulic switch to detect the pressure of a brake pipeline, the over-pressure situation in an air brake system of an aircraft is found earlier and treated earlier to avoid a fault that the aircraft lands with pressure when the aircraft has no ground protection function or ground protection of the aircraft fails to work; and therefore, tire burst accidents are prevented, and the aircraft landing braking safety and reliability are enhanced.
