Description

Brake disc with protective device and method

Technical Field

The invention belongs to the technical field of brake discs, and in particular relates to a brake disc with a protective device and a method.

Background Art

The brake disc is the friction component of the disc brake. In addition to having the strength and rigidity required as a component, it should also have the highest possible and stable friction coefficient, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. The brake is a component in the braking system used to generate braking force to hinder the movement or movement trend of the vehicle. The friction brakes widely used in various types of automobiles can be divided into two categories: drum and disc according to the different rotating elements.

In view of this, a patent application with publication number CN118066230A proposes a brake disc and method with a protective device.

In the above patent application, the vehicle brakes by squeezing the brake disc. Vehicles parked after driving on rainy days and vehicles parked after washing and cleaning have the problem of residual water stains on the brake disc. As a result, the outer surface of the brake disc will cause rust after being stored for a certain period of time, which not only easily damages the brakes and causes safety hazards, but also reduces the service life of the brake disc and increases the cost of vehicle driving.
