Example Embodiment

[0019] The front landing gear wheels of modern aircraft generally do not have brakes, and brake devices are equipped on the wheels of the two main landing gears. The two aircraft main landing gears are usually arranged symmetrically on both sides of the aircraft fuselage. This embodiment takes one of the main landing gear and one wheel installed as an example to illustrate the control process of the aircraft hydraulic brake system main landing gear braking the wheel normally and the take-off line braking. Since emergency braking is not involved, the aircraft emergency braking system is not shown in the figure. Emergency brake system is by prior art.

[0020] In this embodiment, the power supply circuit of the electric valve is mechanically controlled, thereby controlling the slide valve of the electric valve to move and switch the oil circuit, so as to realize the control of the brake wheel 7, that is, the way of stepping on the brake with the normal brake system can also rea...

Abstract

The invention discloses a normal aircraft brake system. The normal aircraft brake system comprises a travel switch, a hydraulic brake valve, an electric valve, an electro-hydraulic servo valve, an antiskid control box and a speed sensor, wherein the hydraulic brake valve is mounted near a pedal mechanism below a cockpit baseplate; and the antiskid control box is mounted in a main gear cabin. The travel switch controls the on/off of the electric valve; and the electric valve is mounted on a hydraulic pipeline at the downstream of the hydraulic brake valve. The electro-hydraulic servo valve is mounted on a hydraulic pipeline at the downstream of the electric valve. The normal aircraft brake system can satisfy the increasing take-off line brake requirement of a traditional normal aircraft brake system, is reasonable in structure, simple and feasible, accords with the ergonomic principle, facilitates to relieve the driver burden, and can eliminate the accident potential due to communication of a take-off line brake switch caused by wrong actions.

Description

technical field [0001] The invention relates to an aircraft wheel hydraulic braking system, in particular to an aircraft hydraulic normal braking system fully capable of taking off line braking. 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. The modern aircraft wheel braking system usually includes a normal braking system (working medium is hydraulic oil) and an emergency braking system (usually compressed gas). The emergency braking system is a safety measure for the driver to take after the normal braking system fails. Due to the increase of aircraft take-off thrust, the brake pressure required for take-off line brakes is much higher than that required for normal brakes, especially carbon brakes. The existing normal brake system can no longer meet this requirement, an...
