An independent friction block brake pad

Abstract

The invention discloses an independent friction block brake pad, and belongs to the technical field of braking. The independent friction block brake pad comprises a steel back, brake blocks, elastic elements, guide sleeves, a dovetail block, small shafts and linings, wherein the brake blocks are fixed on one side of the steel back respectively through the small shafts and the linings respectively; the other side of the steel back is connected with the dovetail block; positioning plates are arranged between the brake blocks and the steel back; each brake block consists of at least three friction blocks; the elastic elements and the guide sleeves are positioned between the positioning plates and each friction block. According to the technical scheme, an independent friction block combination is adopted, each friction block is connected with each lining by adopting each independent small shaft, and independent elastic elements and the guide sleeves are arranged correspondingly below the friction blocks; during assembly, the elastic elements of different specifications can be matched with the friction blocks according to the position of each component of the brake pad, so that the effects of flexibly configuring the friction blocks and freely adjusting the heights of the friction blocks and brake stress are achieved.

Description

technical field [0001] The invention belongs to the technical field of brakes, and relates to a shaft-disc brake pad structure, in particular to a brake pad with an independent friction block. Background technique [0002] The brake pad is an important braking component in the braking device and the braking system. The structure of the brake pad is one of the main factors affecting the braking performance, especially in the shaft-disc brake system. Due to the The radial linear velocity of the disc increases linearly from the inside to the outside, resulting in inconsistent friction power on the friction surface, resulting in unstable braking performance and a large difference in the thickness of the inner and outer rings of the brake material, that is, the phenomenon of eccentric wear. Therefore, after long-term use of the brake disc, the disc surface Often uneven. Therefore, the structural design of the brake pad should not only be strong and reliable, but also need to ove...

Problems solved by technology

During the braking process, because the positions of the three rivets that fix the brake block are involved with each other or the adjustment height is limited, the braking of the brake pads is not stable enough, and eccentric wear occurs, especially when braking at high speeds, the resulting pressure is high and the temperature is high. , the above situation is more obvious

[0005] The general polygonal brake block and the brake pad composed of spherical floating structure are firstly pressurized and sintered the cold-pressed brake block directly on the frame, then assembled on the spherical support, and finally assembled on the polygonal steel plate through the circlip. On one side of the back, the structure is complicated to assemble and requires high precision. The spherical surface and the elastic circlip can play a certain role in preventing partial wear, but the phenomenon of partial wear still exists, and the brake pads fall off from the spherical support, causing traffic accidents. pose a greater security risk
