Problems solved by technology

The heat insulation device in this invention solves the problem of warping and deformation under the high temperature after braking, but its heat insulation effect is similar to that of steel heat insulation disks, and it cannot meet the requirements of combining high temperature brake disks after braking with cylinders made of non-high temperature resistant materials. The function of the seat assembly is separated

Embodiment Construction

[0054] This embodiment is a composite pad for a certain type of machine brake device, including a welding assembly 5 and a plurality of gasket groups; each gasket group is composed of an inner gasket 6 and an outer gasket 7 . Each gasket group is loaded into each gasket mounting hole on the disc surface of the welding assembly 5 respectively; the inner gasket 6 in the gasket group is located on the side where the welding assembly has a heat insulator, and the inner gasket The small outer diameter end of the inner gasket is sequentially loaded into the inner gasket via hole in the center of the pad 4, the inner gasket via hole in the center of the heat insulating part 2, and the gasket installation hole in the center of the frame 1, so that the outer circumferential surface of the inner gasket is stepped The end surface of the outer gasket 7 is fitted to the end surface of one end of the skeleton 1 in the welding assembly 5; the outer gasket is located on the other side of the w...

Abstract

The invention relates to a combined type pallet for a brake wheel. The combined type pallet for the brake wheel comprises a welding assembly and a plurality of gasket groups. Each gasket group is composed of an inner gasket and an outer gasket. The gasket groups are separately arranged in gasket mounting holes on the surface of a circular disk of the welding assembly. The inner gaskets in the gasket groups are positioned on the side, where a heat insulation piece is arranged, of the welding assembly, and the outer gaskets are positioned on the other side of the welding assembly, and the innergaskets are riveted with the outer gaskets. When the gasket groups are assembled with the welding assembly, the gasket groups and the welding assembly are combined into the combined type pallet. According to the combined type pallet for the brake wheel, the factors that pressure affects the deformation of the pallet welding assembly and the thermal deformation of materials caused by the heat transfer of a high-temperature brake disc after the brake are eliminated; and meanwhile, the heat insulation piece is additionally arranged, so that the heat insulation effect is greatly strengthened, anda cylinder seat assembly composed of non-high-temperature resistant materials is protected.

Description

technical field [0001] The invention relates to the field of aircraft braking, in particular to a composite pad used for uniform loading and heat insulation of a brake wheel brake device. technical background [0002] The brake wheel generally consists of a wheel assembly and a brake device. The brake device is composed of parts or components such as a brake disc, a cylinder seat, a piston assembly, and a brake housing. When braking, high-pressure oil enters the piston cavity, and the piston moves forward under the pressure, pressing the pressure disc to the moving disc and the static disc. Keys are passed to the wheel assembly to brake or turn the aircraft. When the aircraft brakes, in order to ensure that the force of the piston is evenly loaded on the pressure plate, and to avoid partial wear of the brake disc due to excessive local pressure, resulting in brake failure, a steel pad is often added between the pressure plate and the piston. , Install the brake disc wear ...
