Description

Technical Field

[0001] The utility model relates to the field of brake discs, in particular to a wear-resistant automobile brake disc. Background Art

[0002] In the vehicle's braking system, the disc brake structure is now commonly used. When braking, the friction between the friction pad in the brake caliper and the brake disc causes the car to slow down. The brake disc has a good braking effect and is easier to maintain than a drum brake. During the braking process, the brake disc will heat up quickly. If the heat dissipation effect of the brake disc is poor, long-term use will easily cause the brake disc to deform and cause danger. At the same time, the existing brake discs also have poor wear resistance and a short service life. Based on this, the utility model proposes a wear-resistant automobile brake disc, which consists of a disc body, a wear-resistant disc, and an end cover seat. The disc body is stacked with multiple layers of heat dissipation discs. Adjacent heat dissipation discs are separated by pads to make the heat dissipation gap larger. The disc body and the wear-resistant disc are connected by a reinforcing block. The reinforcing block can improve the stability of the disc body and the wear-resistant disc, and the wear-resistant disc itself can use the ceramic layer thereon to improve the wear resistance, so that it has strong weather resistance, wear resistance, high temperature resistance and other characteristics to meet the use requirements.
