Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake discs, in particular to a dustproof automobile brake disc. Background Art

[0002] The brake disc is a very important component in the braking system. A good brake disc has stable braking, no noise, and no vibration. The change in size of the brake disc after heating does not increase the travel of the brake pedal. It has better drainage properties, which can reduce the situation of poor braking caused by water or mud.

[0003] When the automobile brake disc is working, it rotates and the friction generates high heat. In order to ensure the service life of the brake disc, a relevant heat dissipation structure needs to be set up to dissipate the heat. The traditional heat dissipation structure generally includes heat dissipation holes and heat dissipation grooves opened on the surface of the brake disc. The heat dissipation path and method are relatively simple. In particular, the heat between the two friction discs cannot be effectively dissipated. In addition, the heat dissipation groove is generally annular, and a large amount of external dust is easily adhered to the groove, which further affects the heat dissipation effect.

[0026] Working principle: The utility model discloses a dustproof automobile brake disc. When in use, multiple groups of linear heat dissipation holes 3 on the surface of the friction outer disc 1 rotate with the brake disc to form a vortex rotation state, and cooperate with the heat dissipation ring groove 6 to dissipate heat. The dustproof net 7 can effectively block external dust and avoid a large amount of dust adhering to the heat dissipation ring groove 6 to affect heat dissipation.
