Description

Technical Field

[0001] The utility model relates to the field of brake pads, and more specifically to a universal wear-resistant brake pad. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the braking system of a car. The quality of all braking effects is determined by the brake pads. Brake pads are generally composed of steel plates, adhesive heat insulation layers and friction blocks. The heat insulation layer is composed of non-heat-conducting materials for heat insulation; the friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc and brake drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking.

[0003] For example, a kind of brake sensitive and safe wear-resistant universal brake pad friction block disclosed in announcement number CN109163040A includes the following raw materials: elastic particles, glass fiber, barite powder, flake graphite, heavy calcium carbonate, vermiculite and resin. The present invention adds elastic particles, glass fiber, barite powder, flake graphite, heavy calcium carbonate, vermiculite and resin in the formula, and the elastic particles can make the brake pad soft and noiseless, heat-resistant and wear-resistant, safe and comfortable, and have a stable friction coefficient, and can also appropriately replace the amount of resin to improve the heat resistance level of the product; glass fiber increases the compressive strength of the product, and the main component of flake graphite is C carbon, which is lubricating, heat-resistant, conductive and heat-conductive, reduces the friction coefficient, and reduces wear; heavy calcium carbonate increases the density of the brake pad and improves the compressive strength; vermiculite increases the porosity of the brake pad and reduces noise.

[0004] It can be seen from the above-mentioned public scheme that the surface of the current brake pad is flat and smooth, so it is not easy to keep the lubricating oil on the front and rear surfaces of the brake pad for a long time. The lubricating oil is easy to lose, thereby reducing the lubricating effect of the brake pad, increasing the wear of the brake pad, and reducing the protectiveness of the brake pad. At the same time, the edges of the brake pad are prone to breakage and warping after long-term use, which not only affects the use effect of the brake pad, but also affects the service life of the brake pad.
