Description

Technical Field

[0001] The utility model belongs to the technical field of brake discs, and particularly relates to a high-strength carbon-ceramic brake disc assembly for motorcycles. Background Art

[0002] With the prevalence of domestic motorcycle races, the driving speed of motorcycles is getting faster and faster. Therefore, when motorcycles participate in races, the requirements for the braking system are more stringent compared to ordinary vehicle conditions.

[0003] Common ordinary cast iron discs will generate extremely high temperatures during emergency braking at high speeds. Moreover, the thickness of motorcycle brake discs is generally 4 - 5 mm. After being exposed to high temperatures for a long time, the matrix material will be damaged, resulting in deformation of the brake disc. When the vehicle brakes, there will be a strong sense of jitter, reducing the braking effect. During the race, it will not only affect the race results, but in severe cases, there will be a risk of braking failure. Content of the Utility Model

[0004] Aiming at the above deficiencies existing in the prior art, the utility model provides a high-strength carbon-ceramic brake disc assembly for motorcycles, which solves the problem of low braking performance caused by brake disc jitter in the braking system of racing motorcycles under extreme working conditions.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A high-strength carbon-ceramic brake disc assembly for motorcycles, including a brake disc and a hub. The inner edge of the brake disc and the outer edge of the hub are fixedly connected and fixed through the cooperation of fastening screws and fastening nuts; the brake disc is of an annular structure, and a number of ventilation holes are arrayed on the surface; the hub is of a circular structure, and a circular connection hole is provided in the middle of the hub; two layers of hollow air ducts are arranged outside the circular connection hole, the outermost layer is an arc-shaped air duct, and the inner layer is a fan-shaped air duct.

[0007] Further, the ventilation holes are of an elliptical hole structure, and the number is 18 - 24.

[0008] Further, 4 - 6 connecting plates are provided on both the outer edge of the hub and the inner edge of the brake disc, and screw holes with a diameter of 10 - 12 mm are provided on the connecting plates.

[0009] Further, an air duct is provided between the brake disc and the hub.

[0010] Further, the length of the arc-shaped air duct is greater than the length of the fan-shaped air duct.

[0011] Further, the width of the fan-shaped air duct is greater than the width of the arc-shaped air duct.

[0012] The beneficial effects of the utility model are as follows:

[0013] (1) In this utility model, the brake disc is made of carbon fiber reinforced ceramic matrix composite material, and the service temperature can reach 1500 degrees Celsius, ensuring that the matrix of the brake disc will not deform during high-speed emergency braking of the motorcycle, thus improving stability;

[0014] (2) In this utility model, by arranging oval ventilation holes in an array on the friction surface of the carbon-ceramic brake disc, the heat in the brake disc can be quickly dissipated during the vehicle's driving process, reducing the heat of the brake disc;

[0015] (3) In this utility model, two layers of hollow air ducts are arranged in an array on the adapter. This design not only reduces the weight of the brake disc assembly, improves the driving range, but also accelerates the flow of air through the large-area hollow structure, causing air masses to continuously form around the brake disc assembly during the motorcycle's driving process, thereby quickly reducing the temperature of the braking system.
