Airplane wheel for integrated double-brake device

Abstract

The invention provides an airplane wheel for an integrated double-brake device. A braking unit of the braking wheel is the integrated double-brake device. The integrated double-brake device comprises two heat reservoirs which share a same brake shell; the inner surface of the drum of the brake shell is provided with a shared bearing disc which divides the heat reservoir of one disc brake into a large brake unit and a small brake unit, so the original single brake of the heat reservoir is changed into two brakes; during braking in taxiing, only the small brake unit runs, so operation conditions are improved while requirements on direction maintenance and turning during taxiing and deceleration of an airplane are met, which enables unfavorable wearing of a carbon disc to be avoided; and the two brake units both operate during braking in landing run or braking at the end of a take-off line, so requirements of a braking function of the airplane are met. According to the invention, the loading capability of a carbon disc is raised to a rated state, so operation conditions are improved, unfavorable wearing of the carbon disc is avoided, the inherent problem of great wearing of the carbon disc during braking in taxiing is overcome, the performance of a carbon-carbon composite friction product is given to full play, and the service life and economic benefits of the carbon disc are improved.

Description

technical field [0001] The invention relates to an aircraft landing gear, in particular to a wheel with connected double brake devices for a single-wheel main landing gear. Background technique [0002] Aircraft carbon brakes refer to the brake device that constitutes the heat storage of the disc brake wheel or the brake disc components of the friction element are completely made of carbon-carbon composite friction materials. Compared with steel brakes, it is light in weight, wear-resistant and relatively The advantages of high heat and high temperature non-bonding have significantly improved the aircraft's technical performance, reliability, safety and maintainability, so it has been widely used in modern aircraft. Carbon-carbon composite friction material brake discs for aircraft carbon brakes are usually referred to as carbon brake discs, or carbon discs. A set of carbon brake devices specifically includes a pressure disc and a pressure disc, several moving discs and stat...

Problems solved by technology

[0003] In order to overcome the poor adaptability to taxiing brakes in the prior art, the large amount of brake wear and the service life of carbon brake discs cannot reach the design given life value under the low-speed and low-energy state of the aircraft taxiing on the ground, the present invention proposes One-piece wheel with double brake device
