Problems solved by technology

However, when the vehicle brakes, the contact position between the brake pad and the brake disc will produce some copper-containing dust due to the friction of the braking force. These dust will enter the environment through air, rainwater, suspended particles, etc., thereby causing environmental pollution.

Abstract

The invention discloses a heat dissipation type brake disc containing rare metal, and belongs to the field of automobile brake pads. The heat dissipation type brake disc aims to solve the problems that an existing automobile brake pad is poor in heat dissipation performance, abrasion resistance and hot crack resistance. The heat dissipation type brake disc comprises a brake mastering disc, the brake mastering disc is provided with one or two friction surface layers, and the brake mastering disc comprises the following raw material of, vanadium-containing pig iron, graphite powder, tin powder,zinc powder, zinc powder, ferrochrome, ferromanganese, barium sulfate and silicon carbide; and each the friction surface layer comprises the following raw material of, aluminum oxide, magnesium oxide,iron powder, steel fibers, carbon fibers, graphite powder, molybdenum disulfide, silicon dioxide and titanium dioxide. The brake disc is formed by sintering the brake mastering disc containing rare metal and the friction surface layers, the friction surface layers are ensured not to generate abnormal wear to the brake disc through reasonable raw material ratio, the heat dissipation performance, the wear resistance and the hot crack resistance of the brake disc are enhanced, the wear rate is reduced, the requirement of high-speed braking can be met, the braking reliability is improved, and theservice life of the brake disc is prolonged.

Description

technical field [0001] The invention relates to the field of automobile brake pads, in particular to a heat dissipation type brake disc containing rare metals. Background technique [0002] With the continuous increase of the number of automobiles in our country, the pollution problems caused by this have been paid more and more attention by people. [0003] At present, the brake materials of the existing automobile brake pads mostly use metal copper. Copper is a key component in the design of brake pads. It not only inhibits the wear, noise and vibration of brake pads and brake discs, but also helps It is used to improve the friction stability of brake pads and brake discs at various operating temperatures. However, when the vehicle brakes, some copper-containing dust will be generated at the contact position between the brake pad and the brake disc due to the friction of the braking force. These dust will enter the environment through air, rainwater, suspended particles, ...
