Description

brake disc

[0001] A brake disc, the present invention especially refers to a brake disc that strengthens the overall pressure resistance, impact resistance and deformation resistance (such as thermal deformation resistance) of the brake disc.

Any vehicle, such as a bicycle, a motorcycle or an automobile, the braking system is one of the most important systems. A good braking system can ensure that the vehicle can slow down the speed or stop immediately according to the environment. Traveling in response to an emergency (such as avoiding a vehicle collision). Up to now, there are many types of brake systems, among which the disc brake method is the most common, which is used to clamp the brake disc with the disc, and gradually reduce the speed of the wheel through friction to stop. [0003] As mentioned above, in this type of brake disc assembly, after the brake disc and the plate are rubbed at high speed each other, high temperatures will be generated. It is understandable that when the brake disc is in a high-temperature environment as a whole, the temperature of the entire disc body will gradually rise, which will cause the disc body of the brake disc to deform and cause the vehicle to produce vibration and abnormal noise, and the braking effect is poor. The disc is mainly made of two different materials, as shown in Figure 1, which is a generally known brake disc structure, as shown in the figure, the brake disc 1 is mainly composed of a disc body 11 and a drum 12.
