AI Technical Summary

Technical Problem

The existing disc brake systems of new energy vehicles are susceptible to mud, dust and dust. The brake disc lacks heat dissipation devices, which leads to accelerate wear of the brake pads, reduces the life and performance of the brake system, and affects driving safety.

Method used

A split outer ring hub brake device is designed, including brake calipers, brake discs, airflow diffusers, side stain removal plates, edge stain removal plates, ventilation holes and ventilation grooves. The brake disc is cooled through the airflow diffuser and the jet pipe, and the side and edge decontamination plates remove sand and dust from the surface of the brake disc.

Benefits of technology

It realizes the self-cleaning and self-cooling effect of the brake disc, protects the surface and brake pads of the brake disc, extends the life of the brake system, improves driving safety, and saves vehicle usage costs.

Abstract

The utility model belongs to the technical field of new energy automobile braking, and discloses a new energy automobile split type outer ring hub braking device which comprises a brake caliper, a brake disc is installed on the brake caliper in a matched mode, two airflow diffusers are installed at one end of the brake caliper, the two airflow diffusers are fixedly installed on the two sides of the brake caliper respectively, and the two airflow diffusers are connected with the brake caliper. Two side dirt removing plates and an edge dirt removing plate are installed at the other end of the brake caliper, the two side dirt removing plates are installed on the two sides of the brake caliper respectively, one ends of the two side dirt removing plates are tightly attached to the disc faces of the two sides of the brake disc, and the edge dirt removing plate is installed on the upper portion of the brake caliper. One end of the edge decontamination plate clings to the edge of the brake disc. Under the combined action of the decontamination structure and the cooling structure, the surface of the brake disc and the brake pad are protected, the working temperature of the brake disc is reduced, the service life of a brake system is prolonged, the performance of the brake system is improved, the driving safety is enhanced, and the vehicle using cost is saved.
