Description

Technical field [0001] The invention relates to the technical field of mechanical braking, in particular to a heavy mechanical brake pad and a processing method thereof. Background technique [0002] Brake pads are also called brake pads. In the brake system of heavy machinery, brake pads are the most critical safety parts. The brake pads play a decisive role in the effectiveness of all braking. [0003] The earlier car brake pads were asbestos type brake pads, but asbestos has been confirmed by the medical community to be a carcinogen. Every time you brake, the brake pads will emit millions of asbestos fibers into the air. The needle-like fibers can easily enter the lungs and stay there, causing irritation and eventually lung cancer; in addition, asbestos type There is another important problem with brake pads: As asbestos is thermally insulated, its thermal conductivity is particularly poor.

Problems solved by technology

Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and the needle-like fibers can easily enter the lungs and stay there, causing irritation, which can eventually lead to the occurrence of lung cancer; in addition, asbestos-type There is another important problem with brake pads: because asbestos is adiabatic, its thermal conductivity is particularly poor. After repeated use, the brake will cause heat to accumulate in the brake pads. After the brake pads become hot, their braking performance will decrease. Changes, to produce the same friction and braking force will require more times to step on the brakes, if the brake pads reach a certain temperature, it will cause brake failure

However, the formula design of some semi-metallic brake pads often has a certain degree of blindness, which causes some inherent shortcomings of semi-metallic brake pads to be magnified, such as serious corrosion under the action of moisture, and greater damage to brake drums or brake discs. Big and so on
