Abstract

An organic fibre brake pad with satisfactory radiating effect comprises the following components according to weight percentages: 5-9% of cashew nut oil friction powder, 5-7% of tyre powder, 4-8% of chromite, 4-7% of calcined petroleum coke, 3-7% of crystalline flake graphite, 4-7% of squama-shaped aluminium powder, 4-7% of ceramic fibre, 4-7% of antimony sulphide, 4-7% of brass fibre, 3-5% of glued alumino-silicate fibre, 9-12% of vermiculite powder, 10-15% of phenolic resin, 7-10% of barite, 0.5-1% of polyacrylonitrile fibre, 3-6% of wood pulp fibre, 3-6% of viscose fibre and 3-6% of bamboo carbon fibre; the invention is especially applicable to a rear brake with comparatively high brake comfort requirement of a family car and the like, after the brake pad is used, the car brake is sensitive, the braking is stable without brake scream, comfort performance is good, and the brake drum or brake disc has no damage and ash falling in long-term use.

Description

technical field [0001] The invention relates to an automobile brake pad, in particular to an organic fiber brake pad with good heat dissipation. Background technique [0002] The performance of semi-metal brake pads or metal-less brake pads currently on the market is not very good. They are severely corroded under the action of moisture, and the noise is high when braking, and there is a brake squeal; the damage to the brake drum or brake disc is relatively serious. Large, the brake system is easy to lock if it is not used for a long time. In addition, most semi-metallic or metal-less brake pads are prone to dust generated during use. These dusts are adsorbed on the wheel hub. Because it is difficult to clean, it is easy to cause corrosion of the wheel hub due to its long-term influence. Although organic fiber brake pads can solve the above problems to a certain extent, the existing organic fiber brake pads do not have good heat dissipation, and long-term use may easily lea...
