Problems solved by technology

However, during the preparation of the drum brake lining with a semi-arc shape, there will be machining errors in the semi-arc structure, and the accumulation of installation errors will make the drum brake lining and its frictional couple in the braking process. It is difficult for the friction pair to achieve comprehensive friction, and only after a long enough running-in can effective friction be generated

Abstract

The invention belongs to the technical field of drum-type parking brake linings for automobiles, and discloses a drum-type parking brake lining for an automobile. In the technical scheme, the drum-type parking brake lining consists of a brake lining body and a friction increasing layer stuck to the arc-shaped surface of the brake lining body, wherein the friction increasing layer is made by performing the procedures of burdening, mixing, spraying, baking and the like on silicon carbide micro powder of 2,000-3,000 meshes, silicon carbide micro powder of 300-450 meshes, aluminum oxide micro powder, modified high bauxite micro powder and high-temperature-resistant gum for an automobile brake. By adopting the brake lining having the structure, the friction surfaces of mating plates are prevented from being damaged during friction braking between the mating plates, thereby effectively enhancing the initial braking force of the brake lining, and achieving friction force which can meet a certain standard more effectively at the initial use stage of a friction material of the brake lining.

Description

technical field [0001] The invention belongs to the technical field of automobile drum type parking brake linings, in particular to an automobile drum type parking brake lining and a preparation method thereof. Background technique [0002] Brake linings are divided into disc brake linings and drum brake linings, also known as brake pads, as key components and wearing parts for safe driving of motor vehicles, mainly made of friction materials composed of reinforcing materials, fillers and adhesives made. The drum brake lining has a semi-circular arc structure, which effectively fits with the circular brake pair (brake drum) when the brake is applied, and generates sufficient braking force through a certain braking pressure. Make the vehicle stop safely. However, during the preparation of the drum brake lining with a semi-arc shape, there will be machining errors in the semi-arc structure, and the accumulation of installation errors will make the drum brake lining and its f...
