Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of brake discs and relates to a high-performance carbon-ceramic brake disc for racing vehicles. Background Art
[0002] The average speed of the racing vehicles is maintained at 250km / h, and the top speed may even reach over 300km / h. When braking at top speed, it usually only takes 3-4 seconds to decelerate from 300km / h to 0km / h to ensure the safety of the race. This requires the brake disc to have excellent comprehensive performance to meet the needs of the above racing. It is precisely because of the special road conditions and race conditions of the racing vehicles that the brake disc will generate high temperature when working. The temperature of professional racing vehicles can reach up to about 1000℃ when braking. When the heat dissipation effect of the brake disc is poor and the matcha action area of the brake disc cannot reach the extreme uniform temperature, it will seriously affect the use effect of the vehicle. Not only will the braking performance affect the race results, but it may even result in brake failure, threatening the life safety of the driver. Heat dissipation effect has become an important consideration for brake discs used in racing vehicles. Carbon ceramic brake discs have emerged to replace traditional metal discs, but most carbon ceramic brake discs are only used in ordinary road conditions. The maximum operating temperature of the brake disc is below 500°C. Relying on its own material properties, it can achieve rapid cooling, and the requirements for structural design are not high. However, when used in racing vehicles, its operating temperature reaches over 1000°C. This requires carbon ceramic brake discs to rely on their own material cooling while combining the most excellent structural design to achieve rapid cooling of the brake disc as a whole.
