Problems solved by technology

[0004] A brake is a device that has the functions of decelerating, stopping or maintaining a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or decelerates moving parts in the machine. The brakes for automobiles are mainly disc brakes and drum brakes. Among them, disc brakes have higher braking efficiency than drum brakes. Disc brakes have fast heat dissipation, light weight, simple structure, and convenient adjustment. It can be driven in winter and under bad road conditions. The new regulations stipulate that in the field of commercial vehicles, cars above 12T must use disc brakes. At present, many models, such as buses, have begun to use disc brakes, but the operating temperature of disc brakes is high. , which requires more high-temperature-resistant raw materials. At present, the high-temperature resistance, wear resistance and high-temperature friction coefficient stability of disc brake friction materials have certain defects. How to prepare a kind of high-temperature resistance, good wear resistance and high temperature Disc brake pads for buses with a stable friction coefficient have become a technical problem to be solved at present

Abstract

The invention discloses a ceramic high-performance disc brake pad for a bus. The disc brake pad comprises, by weight, 14-18% of modified phenolic resin, 18-23% of a fabric material, 50-60% of filler and 8-10% of ceramic fibers, wherein the ceramic fibers are made of at least two of common aluminum silicate fibers, high-alumina aluminum silicate fibers, aluminum silicate fibers containing chromium oxide, aluminum silicate fibers containing zirconium oxide, aluminum silicate fibers containing boron oxide, polycrystalline alumina fibers and polycrystalline mullite; the fabric material is composed of one or more kinds in mineral fibers, glass fibers and paper fibers. The invention further discloses a manufacturing method of the ceramic high-performance disc brake pad for the bus. The ceramic high-performance disc brake pad for the bus is stable in high-temperature friction coefficient, good in abrasion resistance, simple in manufacturing method and low in cost.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a high-performance disc brake pad for ceramic buses and a preparation method thereof. Background technique [0002] Brake pads are also called brake pads or brake pads. In the braking system of a car, brake pads are the most critical safety parts and play a decisive role in the braking effect. Brake pads are generally made of steel plates, adhesive insulation layers and friction block composition. The friction block is composed of friction material and adhesive. When braking, the friction block is squeezed on the brake disc or brake drum to generate friction with it, so as to achieve the purpose of decelerating and braking the vehicle. It can be seen that the friction block determines the braking performance of the brake pad at high speed and high temperature. The friction material is an important part of the brake pad in the manufacturing process and use process. [0003] T...
