Embodiment Construction

[0033] This embodiment is a heat shield assembly installed on a certain type of aircraft, aviation wheel cylinder block assembly, including a heat shield 1 and two indicating rod frames 2 . The two indicating rod frames are symmetrically distributed on the edge of a plane end face of the heat insulating board, and the lower surface of the horizontal plate in the indicating rod frame is attached to the surface of the heat insulating board, through which the indicating rod frame The vertical plate in the brake device is fixedly connected with the cylinder block assembly in the brake device; the other end surface of the heat shield has an axially protruding reinforcement plate, and a gap is formed between the outer edge and the inner edge of the heat shield The slope is consistent with the installation profile of the cylinder block assembly. After the horizontal plate is fixedly connected to the end surface of the plane end of the heat insulating plate, the edge of the horizontal...

Abstract

The invention relates to a heat baffle component for an air cylinder seat component of an aircraft wheel. Two indication rod frames are symmetrically distributed on the edge of the end face of a planeend of a heat baffle; vertical plates in the indication rod frames are fixedly connected with the air cylinder seat component in a braking device; an axially bulged reinforcing plate is arranged on the surface of the other end of the heat baffle; and an oblique surface formed between the outer edge and the inner edge of the heat baffle is consistent with a mounting profile of the air cylinder seat component. After horizontal plates are fixedly connected with the end surface of the plane end of the heat baffle, the edges of the horizontal plates are flush with the edge of the excircle of the heat baffle. A gap between the heat baffle and the air cylinder seat component is 5-6mm. The heat baffle component is mounted on the air cylinder seat component; heat from the braking device is obstructed by the heat baffle; direct contact of the heat from the braking device with the air cylinder seat component is avoided; the obstructed heat is directly conducted and radiated, so that a temperature of oil in the air cylinder seat component is reduced; and the heat baffle component has the characteristics of simple structure, light weight and convenience in mounting and dismounting.

Description

technical field [0001] The invention relates to a heat insulation plate of an aircraft wheel cylinder block assembly, which belongs to the technical field of aviation machinery and can be used for heat insulation or heat protection of the aircraft wheel cylinder block assembly. Background technique [0002] The aircraft wheel needs to be braked or frequently tapped when the aircraft performs landing braking and taxiing on the ground. When the braking energy of the aircraft wheel accumulates in a large amount, the temperature of the brake disc will rise, and the cylinder block assembly of the aircraft wheel will Under heat radiation or conduction, the temperature of the cylinder seat oil will rise, which will eventually cause the carbonization of the cylinder seat oil or the failure of the sealing ring. Therefore, thermal protection of the cylinder block is required. [0003] At present, there are related technical solutions in the prior art to solve the thermal protection p...
