Description
Technical Field
The invention relates to an aircraft wheel, in particular to a combined aircraft wheel.
Background
The aircraft wheel is an important bearing part of an aircraft landing gear, is also a rotating part, is provided with an aircraft tire and a brake device, is arranged on a wheel axle at the bottom end of a landing gear support post, and is used for taking off, landing and sliding, braking and supporting the aircraft. The nose landing gear wheels are typically without braking devices, known as non-braked wheels; the main landing gear wheel carries a brake device, called a brake wheel.
Here, as a matter of knowledge, as well as an understanding of the present invention, it is necessary to explain the concept of "wheel" and the development of "wheel" slightly. Long ago, far from ancient times, we know the wheel and axle, the simplest and most basic mechanical element or part, and thus invent and create a woodware carrier for vehicles and wheels; the wheel includes: the three components are mainly connected together by mortise and tenon joints. The center of the wheel hub is used for inserting the wheel shaft, and the shaft is supported on the wheel hub, or the wheel hub is supported on the wheel shaft; spokes (spokes or webs, webs) are used to couple and support the rim on the hub. With the development of smelting technology, three integrated copper wheels, iron wheels and steel wheels are cast and forged. The application of the rubber, the rubber tire is mounted on the rim, and various load-bearing traveling wheels such as wheels, engineering machinery wheels and the like in the modern sense are achieved; the rim is also called a rim, and the rim has a raised rim at both end sides for fixing the mounted tire. Further, there are also jurisdictions (wheel jurisdictions) associated with wheels, namely wheel keys, that limit the movement of the wheel on the axle.
The aircraft wheel mainly consists of a wheel hub. The position of the wheel on the landing gear axle is limited and fixed by a boss on the axle and an axle nut, and a wheel key is not used. The aircraft wheel hub comprises a hub (hub), spokes (spokes), a rim (rim), typically a one-piece, or one-piece monolithic structure. Because the aircraft tire is rigid, the two end rims of the wheel rim must be designed into a removable rim or a movable rim so as to be used for mounting and dismounting the tire. In the past, aircraft wheels were mainly made from castings, with lower technical performance; at present, the aircraft wheel is mainly manufactured by a light alloy forging and has high technical performance. With the development of large, heavy-duty aircraft and high-speed aircraft, stronger-load-capacity and larger-size aircraft wheels are required, which brings new challenges to the design and manufacture of the aircraft wheels. In order to configure a larger brake heat reservoir, the wheel cavity is desirably large and deep. The existing wheel structure of the forged piece is mainly divided into a single spoke plate (web) or a bowl shape and a split type, and the longitudinal section of the single spoke plate structure is basically in an E shape and comprises a wheel hub, a spoke and a wheel rim. The split type wheel hub is of a two-single-spoke structure, and the longitudinal sections of the two half wheel hubs are basically E-shaped. The inner cavity of the wheel with the single-spoke plate structure is deep and is the preferred type of the brake wheel, but the structure is complex, and the production and the manufacture are not facilitated. The split structure is convenient to manufacture and maintain, but the inner cavity of a common airplane wheel is shallow and small, a large brake heat reservoir is inconvenient to arrange, and the application is limited. The integrated single-piece integral structure of the hub, the spoke and the rim has the advantages that: succinct, the assembly of being convenient for, structural integrity is good, but also meets the problem in developing. The wheel hub is a large piece of the aircraft wheel. The structural design of the prior airplane wheel has the defects that the hub of the integral airplane wheel is lack of maintainability, and the hub of the integral airplane wheel is required to be disassembled and scrapped when being used and cracked, and basically cannot be repaired; the processing and manufacturing manufacturability is poor, the mechanical property of a large-size (the wheel combining diameter is generally more than 450 mm) hub forging is not high, and the dispersion difference is large; in addition, the size of the forging is large, the structure is complex, the existing forging equipment is difficult to adapt, and higher requirements are put forward on the tonnage of the forging equipment; both of which increase the production cycle time and production cost. Optimizing and improving the structural design of the airplane wheel is an urgent need for production practice and airplane development while improving the production process.
