Anti-falling heat dissipation brake pad

Abstract

The invention discloses an anti-falling heat dissipation brake pad. The anti-falling heat dissipation brake pad comprises a steel backing, a friction plate and a heat dissipation pad arranged between the steel backing and the friction plate, wherein a plurality of first through holes are formed in the steel backing, the friction plate is provided with counter bores, and the number of the counter bores is identical with that of the first through holes; the heat dissipation pad is provided with second through holes, the number of the second through holes is identical with that of the first through holes, the heat dissipation pad is made of heat conduction materials, a plurality of heat dissipation holes are distributed in the heat dissipation pad, and axes of the heat dissipation holes are perpendicular to those of the second through holes; the friction plate, the heat dissipation pad and the steel backing are fixed in the mode that pins sequentially penetrate through the counter bores, the second through holes and the first through holes from top to bottom. The friction plate and the steel backing of the brake pad are firmly fixed and are not prone to fall off, heat dissipation performance is good, and the security coefficient is high.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an anti-falling off heat dissipation brake pad. Background technique [0002] As the speed of the car increases and the load increases, the role of the brake pads becomes more and more important. Existing brake pads are generally fixed by means of friction pads sticking to the steel back. During use, the friction pads are easily detached from the steel back due to shear force. If the brake pads fall off during driving, the consequences will be disastrous. Moreover, the friction lining is tightly attached to the steel back, and the friction lining cannot dissipate heat quickly. If the temperature of the friction lining is too high, the friction coefficient between the friction lining and the brake drum will become smaller, and at the same time, the friction lining and the brake drum will be deformed, resulting in braking. The dynamic efficiency becomes lower, thereby causing ...

AI Technical Summary

Problems solved by technology

Existing brake pads are generally fixed by means of friction pads sticking to the steel back. During use, the friction pads are easily detached from the steel back under the action of shear force.

If the brake pads fall off during driving, the consequences will be disastrous

Moreover, the friction lining is tightly attached to the steel back, and the friction lining cannot dissipate heat quickly. If the temperature of the friction lining is too high, the friction coefficient between the friction lining and the brake drum will become smaller, and at the same time, the friction lining and the brake drum will be deformed, resulting in braking. Lower dynamic efficiency, resulting in safety hazards
