Description

Technical Field

[0002] The motorcycle disc brake assembly is mainly responsible for converting the rider's braking operation into braking force to slow down or stop the vehicle. It is a device that drives the brake pads to clamp the brake disc through a hydraulic system to achieve braking. Its core components include brake discs, calipers, brake pads and oil pumps. It has the advantages of high braking efficiency, good heat dissipation performance, convenient maintenance and strong drainage. It is widely used in current motorcycles. When the disc brake assembly is used, the brake disc is exposed to the air, and some designs have heat dissipation holes. Although it can achieve the effect of quickly dissipating heat and reducing thermal decay, the brake disc is exposed during riding and is often covered with dust or gravel. Especially when riding on muddy roads, mud adheres to the brake disc, which can easily lead to brake failure. Moreover, when foreign matter adheres to the brake disc, it is easy to cause wear on the surface of the brake disc during braking, affecting its service life. In addition, during some long-distance riding, when on a downhill road for a long time, due to frequent braking, it is also easy to cause more heat to accumulate on the brake disc, resulting in thermal decay, affecting the braking effect, and there is a risk of brake failure. ‌‌ Summary of the invention
