Description

Brake pad with good heat dissipation performance

Technical Field

The utility model relates to a brake block technical field specifically is a brake block of heat dispersion preferred.

Background

The brake block, also called brake block, in the braking system of car, brake block is the most crucial safety part, and the brake block plays decisive role to all good and bad brake effect. The brake block is generally composed of a steel plate, a bonding heat insulation layer and a friction block, wherein the heat insulation layer is made of a non-heat-transfer material and aims to insulate heat; the friction block is composed of friction material and adhesive, and is extruded on the brake disc and the brake drum to generate friction during braking, so that the aim of decelerating and braking the vehicle is fulfilled. From the application object, the brake pads are divided into: brake pads for disc brakes, brake pads for drum brakes, brake pads for large trucks; from the composition of the friction material, brake pads are mainly classified into the following categories: asbestos brake blocks, semi-metal brake blocks, less-metal brake blocks, NAO formula brake blocks, ceramic brake blocks and NAO ceramic brake blocks. Ceramic brake pads are a new variety of friction materials, originally developed by the japan brake pad industry in the last 90 th century. The ceramic brake pad is composed of ceramic fibers, a filler substance without iron, an adhesive and a small amount of metal, and has the advantages of high temperature resistance, no noise, no ash falling, no corrosion to a hub, long service life, environmental protection and the like. Although ceramic brake pads are unlikely to replace traditional brake pads in a short period of time, modern automobiles are developing towards high performance, high speed, safety, comfort and the like, which requires that brake systems as important components of automobiles must be safe and reliable, and new brake materials must be continuously developed to meet stricter requirements, and the ceramic brake pads are necessarily a development trend in the future. When the brake pad is used, the friction block is gradually abraded due to the friction effect, the brake pad needs to be replaced in time after the friction material is used up, otherwise, the steel plate and the brake disc can be in direct contact, the brake effect can be lost finally, the brake disc is damaged, and the driving safety is influenced. For your driving safety, please regularly check and replace the brake pads. Automotive friction materials are key materials for friction (contact) brakes and clutches for braking and transmission. The automobile brake block is a key part of automobile brake transmission, and directly influences the driving safety performance of an automobile. The main subjects of the automobile brake in the 21 st century are to be safer, lighter and meet the requirement of environmental protection, which not only needs to develop new materials, but also needs to adopt new structures and new systems so as to greatly improve the comprehensive service performance of the brake and realize the light weight. The performance of the brake system is good and bad, and the normal use of the brake system of the automobile is directly influenced, so that the realization of the performances of comfort, safety and the like of the automobile is concerned.

However, the existing brake pad has the following problems:

1. the heat dissipation performance is still insufficient.

2. The brake block is quite inconvenient to disassemble and assemble.
