Abstract

The invention provides an automobile brake lining which comprises a friction part and a connecting part, wherein the friction part comprises the following components by mass percentage: 10-20% of adhesive, 25-35% of composite fiber, 2-10% of carbon fiber, 5-10% of glass fiber, 2-10% of aramid fiber, 5-15% of friction increasing agent, 2-15% of friction reducing agent, 20-25% of filler, 1-2% of releasing agent, and 0-5% of colorant. The connecting part comprises the following components by mass percentage: 10-20% of adhesive, 30-40% of composite fiber, 0-15% of mineral fiber, 0-15% of friction increasing agent, 0-15% of friction reducing agent, 30-45% of filler, 1-2% of releasing agent, and 0-5% of colorant. With the adoption of the automobile brake lining, the connection between the brake lining and a brake assembly is firmer and more reliable, the material cost of the connecting part is lowered greatly, and great resource waste caused by replacement of the brake lining is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile brake lining and a preparation method thereof. Background technique [0002] In the prior art, the automobile brake lining is a key component of the automobile braking system, and its performance is directly related to driving safety and braking efficiency. At present, the installation of the brake lining of the truck generally adopts the method of mechanical riveting or bolt connection on the brake drum / disc. Since the riveting part / bolt connection part of the brake lining only plays the role of mechanical connection and fixation, and does not participate in the braking friction, the mechanical connection parts will be discarded every time the brake lining is replaced, resulting in a huge waste of resources, which is not in line with National energy conservation and emission reduction policies. Therefore, technical measures should be taken to improve the...
