Embodiment Construction

[0034] This embodiment is used for a static disc assembly of a certain type of brake device. Such as figure 1 As shown, it includes one static plate 1, three protective sheets 2 and 24 rivets 3. Wherein, the three protective sheets 2 are evenly distributed on the inner peripheral surface of the static disk 1 , embedded between the convex keys located on the inner peripheral surface of the static disk, and fixed by rivets 3 .

[0035]The static disk 1 is the prior art, made of carbon-carbon composite material, with a total weight of 3.5kg; the protective sheet is 1Cr18Ni9Ti, and the surface treatment is passivation. The utility model comprises friction discs and 9-15 convex keys. Each of the protruding keys is evenly distributed on the inner peripheral surface of the friction disc, and the distance between adjacent protruding keys forms a key groove. The keyway has a width of 13-18mm and a depth of 12-16mm. In this embodiment, the outer diameter of the static disc is 412 mm...

Abstract

A static disc assembly for aviation airplane wheel braking is provided. Protection pieces are embedded and fixed in the surfaces of protruding keys of a friction disc, the concave arc faces of the protection pieces are attached to the convex arc faces of the groove bottoms of protection piece installation grooves, the convex arc faces of the protection pieces are attached to the concave arc facesof the groove bottoms of the protection piece installation grooves, and grooves in the protection pieces correspond to concave key grooves of a static disc. The stress form of the static disc assemblyis changed, the concave key grooves of the static disc are prevented from being stressed, the service life of the static disc assembly is prolonged, the safety of the static disc assembly is improved, the radial torque of the convex keys of a brake shell can be shared through cooperative use of the grooves of the protection pieces, damage to the static disc due to stress of the grooves of the static disc is avoided, and the service life of the static disc is prolonged.

Description

technical field [0001] The invention relates to the field of aircraft brakes, in particular to a static disc assembly structure for aircraft wheel brakes. Background technique [0002] The aircraft brake wheel comprises a wheel assembly and a brake device, and the wheel assembly and the brake device are mounted on the main landing gear shaft of the aircraft. The wheel assembly is mainly used to bear the weight of the aircraft and support the aircraft; the brake device is mainly used for braking the aircraft. The brake device is mainly composed of a cylinder block, a piston assembly, a brake housing, a compression disc assembly, a moving disc assembly, a static disc, a pressure bearing disc, and a steel pressure bearing disc. The static plate cooperates with the convex key of the brake housing through the key groove, and is fixed on the landing gear of the aircraft. When the aircraft brakes, the brake hydraulic oil enters the cylinder seat under the brake pressure, pushes t...
