AI Technical Summary

Technical Problem

Existing automotive brake discs have poor heat dissipation efficiency, with only a small amount of gas able to enter the heat dissipation vents, resulting in poor heat dissipation.

Method used

Cooling holes are arranged in a ring array on the outer wall of the brake disc, and a cooling groove with a larger diameter is provided. Semi-cylindrical auxiliary grooves are provided on the upper and lower end faces of the brake disc, and arc-shaped and semi-cylindrical auxiliary grooves are provided on the brake pads. Combined with the combination structure of guide rod and coil spring, heat dissipation and friction are enhanced.

Benefits of technology

It significantly improves gas entry efficiency, enhances airflow cooling effect, expands heat dissipation area, improves braking response speed and stability, and extends component lifespan.

Abstract

The utility model provides automobile brake assembly structure relates to brake assembly technical field, include: brake disc, the cooling hole that is equidistantly seted up with ring array shape is seted up on brake disc outer wall, cooling hole is circular hole shape structure, the cooling groove of cylindrical slot structure is seted up with one cooling groove in every cooling hole place on brake disc outer wall, the diameter of cooling groove is greater than the diameter of cooling hole. The utility model is in the heat dissipation performance aspect, the ring array cooling hole of brake disc outer wall cooperates the cooling groove of greater diameter, significantly promotes gas access efficiency, enhances the airflow cooling effect, the semicylindrical first auxiliary groove on its upper and lower end surface not only expands the heat dissipation area, still strengthens heat dissipation through increasing surface roughness, the arc second auxiliary groove and semicylindrical third auxiliary groove on the brake pad of the utility model further expand the heat dissipation area, under the synergistic effect of multiple structures, effectively reduce the temperature of brake disc and brake pad in the braking process, avoid the brake performance attenuation caused by high temperature.
