Description

Carbon fiber disc

The model relates to a disc brake part, in particular to a carbon fiber disc with abrasion resistance and light weight.

The existing disc is used in the disc brake system of a bicycle, and the braking force of the bicycle is generated by friction between the disc and the brake pad. However, since most ordinary discs are made of iron discs, although this kind of disc is a wear-resistant structure, its heavier weight also increases the overall weight of the bicycle, which is not conducive to riding in a bicycle competition.

In order to solve the problem that the discs of the iron discs increase the overall weight of the bicycle, some people use carbon fiber discs to make the discs to provide brakes. However, the carbon fiber structure is less resistant to brake wear than the iron discs, so it can reduce the bicycle in use. However, it is easy to wear and damage, and it is not economical to use.

Since the existing carbon fiber discs are not resistant to the wear of the brake pads, they have the disadvantage of being less economical in use. For this reason, the present invention forms a wear-resistant structure at the contact position of the disc and the brake pad, which achieves the effect that the disc is lighter in weight and not easily damaged.

In order to achieve the above creative purpose, the present invention provides a carbon fiber disc, which is provided with a carbon fiber disc body, and an annular wear-resistant layer is formed on two opposite sides around the carbon fiber disc body, and each wear-resistant layer is embedded Set multiple metal powders.

Furthermore, the wear-resistant layers of the present invention are formed on the surface of the carbon fiber disc body.

Furthermore, the wear-resistant layers of the present invention are formed in the surface layer of the carbon fiber disc body.

Furthermore, in the present invention, an annular heat-resistant mesh is embedded in each wear-resistant layer.

Preferably, the heat-resistant mesh sheet of the present invention is a glass fiber mesh sheet or a titanium mesh sheet.

The new model forms a wear-resistant layer embedded with metal powder on the part where the carbon fiber disc provides the brake pads tightly. Through the better wear-resistant characteristics of the wear-resistant layer, the carbon fiber disc has the characteristics of lighter weight and When installed in the disc brake system, it has the function of being wear-resistant and not easily damaged, and has the economic value of light weight and wear resistance.
