Description

Technical Field

[0001] The utility model relates to the technical field of braking, in particular to a novel friction disc combination structure. Background Art

[0002] Among high-speed and heavy-load friction materials, C / C-SiC composite materials have been widely used in the fields of heavy-load and high-speed braking or transmission due to their advantages such as high mechanical strength, good thermal conductivity and stable friction performance, such as braking or transmission devices of aircraft, tanks, and automobiles. Under high-speed and heavy-load conditions, due to the characteristics of the anisotropy of C / C-SiC composite materials, their strength is insufficient and their reliability is poor. At the same time, the material also has the problem of poor heat dissipation, causing the friction surface temperature to be too high, thereby reducing the service life of the friction disc; and the existing metal disc of the moving disc is rivet-fixed with several fan-shaped friction plates to form an overall annular friction plate, but there is a gap between adjacent friction plates, which affects the friction area.
