Abstract

The invention provides a non-asbestos wet-rolled automobile drum type brake block and a manufacturing method thereof. According to the manufacturing method of the drum type brake block, aluminum silicate, zinc powder, blanc fixe, needle-shaped wollastonite, compound graphite, cellulosic fibers, aramid fibers, steel fibers and phenolic resin are poured into a harrow type mixer to be mixed, liquid resin is added in the mixing process, the mixed materials are pulverized by a pulverizer and then are placed in shade places to be dried for 3-4 hours, the dried materials are then put into a hopper of a roller press to be rolled and then are conveyed into a cutting forming machine, the materials are coated with glue and then are adhered to the shoe of the brake block, conventional outer arc polishing, spraying, mark printing and accessory installation, riveting and packaging are carried out after heat treatment and cooling, and finally the brake block is formed. According to the non-asbestos wet-rolled automobile drum type brake block and the manufacturing method thereof, due to the fact that the liquid resin and the wet-rolling technique are applied, the work environment of workers is greatly improved, energy consumption is greatly reduced, environmental performance is good, and the brake block manufactured with the method is free of heat fading, stable in friction coefficient, good in friction performance, stable in braking, sensitive, reliable, and long in service life.

Description

technical field [0001] The invention relates to a drum brake pad used for parking and driving brakes of automobiles, in particular to an asbestos-free wet rolling automobile drum brake pad and a production method thereof. Background technique [0002] Brake pads are a vital part of motor vehicles. The quality of the braking performance is directly related to the safety of parallel vehicles. Since the birth of the first automobile brake pads, people have been continuously improving the various performances of brake pads. With the continuous progress of the automobile industry, the requirements of automobiles for brake pads are also increasing, and the paint puts forward higher requirements for the thermal stability, wear resistance, and thermal recession of brake pads. Existing friction pads (brake pads) used for braking and transmission mainly include disc brake pads and drum brake pads. Among them, the drum brake has a cast iron piece similar to a tambourine, called a brake...
