Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 As shown, a brake pad in this embodiment includes a brake pad base plate 1 and a brake lining 2 fixed by bonding. As the biggest improvement of this embodiment, such as figure 2 As shown, a metal powder particle coating 3 is provided on the bonding surface of the brake pad base plate 1 and the brake lining 2, and the brake pad base plate 1 and the brake lining 2 are passed through the metal powder particle coating 3 Spray adhesive 4 bonding on top. Preferably, in this embodiment, the particle size of the metal powder particle coating is -20 mesh to +100 mesh, and the ...

Abstract

The invention relates to the technical field of automobile braking and particularly discloses a brake block and a method for improving the bonding strength of a brake block bottom plate and a brake lining. By arranging metal powder particle coatings on the bonding surfaces of the brake block bottom plate and the brake lining, a layer of quite rough structure with an uneven macro surface is formed on each bonding surface, and certain porosity is achieved among metal powder particles. Compared with the prior art, the micro superficial area of the bonding surfaces is greatly increased, and by spraying a bonding agent on the metal powder particle coatings for bonding, the bonding strength is greatly improved. The shear strength of the brake block is improved, and the safety performance of the brake block is improved.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a brake pad and a method for improving the bonding strength of a brake pad bottom plate and a brake lining. Background technique [0002] The structure of a traditional automobile brake pad is mainly composed of a brake pad base plate and a brake lining. A layer of liquid phenolic resin adhesive is pre-sprayed on the surface of the brake pad bottom plate and dried at low temperature. The material of the brake pad bottom plate is generally cold-rolled sheet or hot-rolled sheet. Before the brake lining material is prefabricated, it is a granular mixture containing solid powder binder. After the granular mixture is put into the cavity of the prefabricated mold, it passes through a certain temperature, Under pressure and time conditions, the adhesive undergoes a curing reaction, and finally, the brake lining and the brake pad base plate are bonded together. However, for ...
