Brake pad with dust filter structure

Abstract

The invention relates to a brake pad with a dust filter structure. The brake pad with the dust filter structure comprises a brake pad body, a dust collection part, a dust filter box and an air inducing mechanism, wherein a dust discharge groove is formed in the brake pad body; the lower end of the dust discharge groove communicates with the dust collection part; and a filter screen is fixedly connected to the inner wall of the dust filter box in a direction vertical to a dust discharge channel. In the case that lots of dust is generated due to continuous wear between the brake pad body and a brake disc, the dust can be discharged into the dust collection part through the dust discharge groove, the air inducing mechanism discharges the dust in the dust collection part into the filter box, and the dust is prevented from being accumulated on working surfaces of the brake pad body and the brake disc to cause adverse effects to a brake force of a brake system; and in addition, through the arrangement for the filter box, the dust generated in a brake process can be filtered, clean air is discharged into the atmosphere, and the dust is effectively prevented from being directly dischargedinto air, so that air pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a brake pad with a dust filtering structure. Background technique [0002] Automobile brake pad refers to the friction material fixed on the brake disc rotating with the wheel. The friction block on the brake pad is subjected to external pressure to generate friction, so as to achieve the purpose of decelerating the vehicle. The brake pad is generally composed of a back plate and a heat insulation layer. and friction blocks. When the existing brake pads brake the car, the friction between the brake pads and the brake disc will produce dust. If the dust is not discharged in time, it will easily adhere to the surface of the friction block, which reduces the friction coefficient of the brake pads, reduces the braking force of the car, and affects the braking force. Effects, among other things, dust is an air pollutant, and its direct release into the atmosphere can lead to envir...

Problems solved by technology

When the existing brake pad is braking the car, the friction between the brake pad and the brake disc will produce dust. If the dust is not discharged in time, it will easily adhere to the surface of the friction block, which reduces the friction coefficient of the brake pad, reduces the braking force of the car, and affects the braking force. effect, besides, dust is an air pollutant, and its direct discharge into the atmosphere will cause environmental pollution
