Problems solved by technology

But at present, the shortcomings of semi-metallic brake pads are becoming more and more prominent, such as serious corrosion under the action of moisture, high noise and vibration during braking, and certain damage to the brake disc. Most semi-metallic brake pads are easy to wear during use. The generated dust, which is adsorbed on the wheel hub, is difficult to clean, and it is easy to cause corrosion of the wheel hub due to its long-term influence, which greatly restricts the application of semi-metallic brake pads

Abstract

The invention discloses a vanadium-contained semimetallic brake block. The vanadium-contained semimetallic brake block includes, by weight, 5-7 parts of red copper fibers, 3-6 parts of potassium hexatitanate whiskers, 4-5 parts of barium sulfate, 15-25 parts of ferrovanadium powder, 4-6 parts of frictional powder, 13-15 parts of short stainless steel fibers, 6-10 parts of graphite, 2-4 parts of cellulosic fibers, 7-9 parts of coke blacking, 1-5 parts of modified resin nitrile fibers, 3-7 parts of chromite ore fine, 1-5 parts of nitrile rubber, 5-9 parts of ceramic adhesive agents and 8-10 parts of spray-bounded aluminum silicate fibers. The brake block obtained by material mixing, steel backing treatment, press molding, heat treatment, packaging and storage is low in wear rate, not prone to being dusty, high in density, good in heat dissipation, small in vibration, low in noise and high in corrosion resistance. The whole manufacturing process is simple, stability is good, cost is low and the cost-performance ratio is high.

Description

technical field [0001] The invention relates to a brake pad, in particular to a vanadium-containing semi-metal type brake pad. Background technique [0002] The braking system is one of the most important safety systems on a car, and the brake pads are an important part of the entire braking system. Conventional brake pads are divided into: 1. Asbestos type, because asbestos fibers have high strength and high temperature resistance Therefore, it meets the requirements of brake pads and clutch discs, and has the tensile strength of fibers and the hardness and wear resistance of high-grade metal materials. Due to the poor thermal conductivity of asbestos-type brake pads, it is easy to produce toxic gases that endanger human health. It has been eliminated by our country; 2. Asbestos-free organic type mainly uses glass fiber, aromatic polyester fiber and other fibers as reinforcement materials, and its performance mainly depends on the type of fiber and other mixtures. It is the...
