Embodiment 1

[0023] In this embodiment, the automatic brake is set to one level. The automatic brake anti-skid valve uses an electro-hydraulic servo valve 3 as a common anti-skid valve.

[0024] An aircraft hydraulic brake system with automatic braking capability. The system includes: hydraulic brake valve 1, electro-hydraulic servo valve 3, pressure reducing valve 2, hydraulic-electric valve 7, first conversion valve 8, automatic brake switch K, throttle The device 9, the one-way valve 10, the speed sensor 5 and the anti-skid control box 4.

[0025] Among them, hydraulic brake valve 1, electro-hydraulic servo valve 3, speed sensor 5 and anti-skid control box 4 constitute a normal brake system. The normal brake system is set according to the existing technology.

[0026] Automatic brake switch K, pressure reducing valve 2, hydraulic valve 7, first switching valve 8, throttle 9, check valve 10, speed sensor 5, anti-skid control box 4 constitute an automatic brake system. The speed sensor 5, the...

Embodiment 2

[0036] This embodiment is different from the first embodiment in that the automatic braking system is two-stage. A two-stage automatic brake is set, and the decompression pressure of one pressure reducing valve is lower than that of the other pressure reducing valve.

[0037] This embodiment is an aircraft hydraulic brake system with automatic braking capability, including hydraulic brake valve 1, electro-hydraulic servo valve 3, first pressure reducing valve 11, second pressure reducing valve 12, first hydraulic and electric valve 13, and Two-hydraulic electric valve 14, first switching valve 8, second switching valve 15, first automatic brake switch K1, second automatic brake switch K2, throttle 9, one-way valve 10, speed sensor 5 and anti-skid control box 4 .

[0038] Among them, hydraulic brake valve 1, electro-hydraulic servo valve 3, speed sensor 5 and anti-skid control box 4 form a normal brake system. The first automatic brake switch K1, the second automatic brake switch ...

Abstract

The invention provides an aircraft hydraulic brake system with an independent antiskid function. The system comprises an automatic brake system of primary brake and an automatic brake system of secondary brake, wherein the automatic brake system of primary brake comprises an automatic brake switch K, a reducing valve, an electrohydraulic valve, a first conversion valve, a throttler, a check valve,a speed sensor and an anti-skid control box; and the automatic brake system of secondary brake comprises a first automatic brake switch K1, a second automatic brake switch K2, a first reducing valve,a second reducing valve, a first electrohydraulic valve, a second electrohydraulic valve, an electrohydraulic servo valve, a first conversion valve, a second conversion valve, a throttler, a check valve, a speed reducer and an anti-skid control box. The aircraft hydraulic brake system is used for executing anti-skid control with independent or common anti-skid valve, so that an aircraft normal brake system has an automatic brake function, the running range of the normal brake system can be improved and expanded, the choice of an automatic brake mode is provided for drivers, the distance of landing run is shorted by 35 percent, aircraft take-off and landing safety can be guaranteed, the airfield runway utilization rate and equipment utilization rate can be increased, and the economic, social and military benefits are remarkable.

Description

Technical field [0001] The invention relates to an aircraft wheel hydraulic brake system, in particular to an aircraft hydraulic brake system with automatic braking capability. Background technique [0002] Aircraft wheel brake system is a component of modern aircraft landing gear. It is the basic guarantee equipment for the safe operation of aircraft take-off, landing roll and ground taxi control. It is used to ensure that the taxi distance is shortened after landing, and the aircraft is stopped as soon as possible. Prevent the tire from bursting. Ground traffic congestion is a growing problem in many cities that are now accelerating modernization. Air traffic is no exception, with inbound and outbound flights waiting for the runway at the airport. With the development of civil aviation, the issue of the provision of airport runway resources and the utilization of airport runway resources have a significant impact on the safety and rapid arrival and departure of flights. How t...
