Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to an air-cooled brake disc. Background Art

[0002] The brake disc is a very important component in the vehicle's braking system. It also rotates when the vehicle is moving. The braking force of the brake disc comes from the brake caliper. According to the different materials, it is divided into carbon fiber ceramic brake discs and metal brake discs. The brake disc generates braking force by clamping the brake disc with the brake caliper. When you step on the brake, it clamps the brake disc to slow down or stop the car. During use, the existing brake disc is limited by its own ventilation and heat dissipation performance, which causes the heat generated by the brake disc during continuous braking to dissipate slowly, affecting the overall cooling effect of the brake disc. Therefore, we propose an air-cooled brake disc. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model ventilates through the ventilation duct formed between the front brake disc body, the rear brake disc body, the outer partition column and the inner partition column, and at the same time uses the outer air outlet on the outer partition column and the inner air outlet on the inner partition column to increase the ventilation effect. The air guide blades on the inner ring surface of the brake disc hub can generate an air guide airflow when the brake disc body rotates, thereby accelerating the air flow around the front brake disc body and the rear brake disc body, ensuring smooth discharge of the airflow through the front air holes and the rear air holes, thereby improving the ventilation and heat dissipation performance of the brake disc, facilitating the rapid dissipation of heat generated by the brake disc during continuous braking, and ensuring the overall cooling effect of the brake disc.
