Embodiment Construction

[0026] This embodiment describes the technical solution of the present invention in detail by controlling the braking wheel of an aircraft main landing gear.

[0027] This embodiment includes a brake command sensor 1, a control box 2, an electro-hydraulic servo valve 3, an electromagnetic valve 4, a brake wheel 5, a speed sensor 6, an electromagnetic hydraulic lock 7 and a brake pressure sensor 8.

[0028] The brake command sensor 1 is installed under the cockpit floor, is mechanically connected with the pedal mechanism, and is manipulated by the driver stepping on the brake pedal to generate a brake command voltage signal. The brake command sensor 1 has an electrical interface, is electrically connected with the control box 2 through a cable, and sends the brake command voltage signal to the control box 2 . The operating voltage required by the brake command sensor 1 can be provided by the control box 2 .

[0029] Speed ​​sensor 6 is installed on the wheel shaft of the aircr...

Abstract

The invention relates to an airplane electrical signal transmission brake antiskid control system. When brake is carried out, an electro hydraulic servo valve can not output brake pressure, a control box emits a control signal to an electromagnetic hydraulic lock, the electromagnetic hydraulic lock unlocks by energization, the hydraulic power source is switched on, and the brake is carried out on a brake machine wheel with maximum brake pressure. During a brake process, if the machine wheel slips, the control box controls the electromagnetic valve for energization to release pressure. The system is simple and easy to be carried out, the reliability and security of the brake system operation can be greatly increased during taking off, landing rollout processes, the work load of a driver is reduced, even the electro hydraulic servo valve generates fault, the tire burst can be effectively avoided, and the airplane usage safety is ensured.

Description

technical field [0001] The invention relates to an aircraft fly-by-wire brake anti-skid control system, in particular to an aircraft fly-by-wire brake anti-skid control system which still has a failure safety function when an electro-hydraulic servo valve fails. Background technique [0002] The aircraft wheel brake system is a component of modern aircraft landing gear, and is the basic guarantee equipment for the safe operation of aircraft take-off, landing roll and ground taxi control. Prevent punctured tires. Electronic anti-skid brake control systems are widely used in modern advanced aircraft, and the traditional hydraulic transmission control brakes have been developed to control brakes through wires, that is, fly-by-wire brakes. In the fly-by-wire mode, the brake command sensor replaces the hydraulic brake valve. The basic composition of aircraft fly-by-wire brake anti-skid control system includes four accessories of brake command sensor, speed sensor, control box a...
