Embedded brake pad

Abstract

The invention relates to an embedded brake pad. The brake pad, namely an embedded friction body type brake pad, is characterized in that a plurality of friction block components forming friction with a brake disc are arranged on a backboard of the embedded friction body type brake pad; each friction block component is a base plate combined friction block component, a base plate-free combined friction block component or a round recessed fixed plate type friction block component embedded in the backboard; the base plate combined friction block component consists of a friction block, a base plate and an embedded pin; the base plate-free combined friction block component consists of a friction block and an embedded pin; the round recessed fixed plate type friction block component consists of a friction block, a round recessed base plate, an elastic gasket, an embedded cylindrical pin and a dowel. The embedded brake pad is reasonable in design and simple in structure, and has the characteristics of uniform stress, reliable performance, prolonged service life, simplified manufacturing process, improved production efficiency, easiness for assembly, disassembly and replacement, reduction in cost and the like, and the load bearing capability of the friction block is improved while the breakage risks of the friction block are greatly reduced.

Description

technical field [0001] The invention belongs to brakes, in particular to an embedded brake pad made of metal powder metallurgy, which is especially suitable for disc brakes of railway vehicles. Background technique [0002] As we all know, brake pads are an important part of brakes, and are widely used in transportation tools such as railway vehicles, automobiles, motorcycles, and airplanes, and sports machinery such as wind power generation. Among the high-speed train brakes, the disc brake structure is the most widely used. The friction pair of the disc structure brake is composed of a brake disc and a brake pad. The frictional brake pad consumes the energy of the moving vehicle through the mutual friction between the brake disc and the brake pad to achieve the purpose of stopping the vehicle. As the speed of the train increases, the braking energy increases, requiring the friction pair to achieve the braking function under high temperature and high speed conditions, whic...

AI Technical Summary

Problems solved by technology

Although the above-mentioned patents solve the structural design of the brake pads and the reliability of the friction pair, the disadvantages and shortcomings of the above-mentioned patents are that the structure of the brake pads is complicated, the manufacturing cost is high, and the combination of the friction block and the back plate The friction block and the back plate are connected together by the riveting method. Although the riveting method can make the two parts have the advantage of reliable connection strength, the riveting method must design the friction block into a hole structure to meet the riveting process. conditional requirements

At the same time, it is difficult to add buffer pads to the brake pads of this riveted structure, which is not conducive to improving the uniformity of contact stress distribution and improving the life of brake pads and brake discs.
