Abstract

The invention relates to a thermal insulation device used for an aviation braking airplane wheel. The thermal insulation device used for the aviation braking airplane wheel is used for conducting heat insulation on the aviation braking airplane wheel. The disk type aviation braking airplane wheel is generally composed of an airplane wheel assembly and a braking device. After an airplane is braked, a braking disk absorbs a large amount of airplane kinetic energy and converts the airplane kinetic energy into heat energy so that the temperature of the braking disk can be raised. While the airplane is unceasingly improved and upgraded, the temperature of the braking disk is further raised and the temperature of hydraulic oil is further raised. However, the spatial size and the basic structure of the braking airplane wheel of the improved airplane are relatively limited, and no large changes or large adjustment exists. According to the thermal insulation device, a suspended metal disk is applied and is made to make no contact with the braking disk so that the temperature of the metal disk can be lowered, and direct radiation of heat can be effectively reduced under the condition that the size and the weight are not affected.

Description

technical field [0001] The invention relates to a heat insulation device for aviation brake wheels, which is used for heat insulation of aviation brake wheels. Background technique [0002] Disc aviation brake wheels generally consist of a wheel assembly and a brake device. The brake device is composed of parts or components such as a brake disc, a cylinder block assembly, and a brake housing. When the aircraft brakes, the brake disc absorbs a large amount of aircraft kinetic energy and converts it into heat energy to increase the temperature of the brake disc. When the temperature of the brake disc rises, it will transfer and diffuse heat to the surroundings and cause the temperature of the surrounding materials to rise. Modern aircraft brake discs are generally made of carbon / carbon composite materials, which can withstand high temperatures as high as 600°C to 1200°C. However, the materials adjacent to the brake disc include aluminum alloy materials, rubber materials an...
