Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a self-ventilating and heat-dissipating disc brake disc. Background Art

[0002] The disc brake, commonly known as the disc brake, is a very important component in the braking system. It is a brake disc connected to the wheel. The disc brake disc rotates with the wheel when the car is driving. When braking, the high-pressure brake oil pushes the brake pad, and the friction between the brake pad and the disc brake disc plays a role in slowing down or stopping the car. The potential energy of friction is eventually converted into heat energy, which will inevitably make the brake disc need to withstand high temperatures. Based on the limitations of material properties and processes, the disc brake disc can only be provided with various heat dissipation holes to increase the surface area and improve the heat dissipation efficiency. This method has the disadvantage that the heat dissipation efficiency is difficult to improve. When the outer ring of the disc brake disc is subjected to high heat, the inner ring of the disc brake disc contacts the heat. Under long-term heating conditions, the disc brake disc is squeezed by the brake pad and is prone to distortion.

[0003] The existing self-ventilating heat-dissipating disc brake disc can refer to the Chinese utility model patent with the authorization announcement number CN217152785U, which discloses a self-ventilating heat-dissipating disc brake disc, including a disc brake disc, which is composed of three parts: a first disc brake pad, a second disc brake pad and a heat-conducting steel ring. The first disc brake pad and the second disc brake pad are both provided with a card slot, and the first disc brake pad is penetrated with at least two first through holes, and the second disc brake pad is penetrated with at least two second through holes. The heat-conducting steel ring is inserted into the card slot, and when braking, the heat is introduced into the heat-conducting steel ring, which avoids the inner disc brake disc from being squeezed and twisted, and the service life of the brake disc is increased. The convex heat-conducting block makes the temperature in the hollow cavity of the heat-conducting steel ring higher, and air convection is formed in the hollow cavity of the heat-conducting steel ring, which accelerates the entry of cold air from the outside into the heat-conducting steel ring, and improves the heat dissipation efficiency of the disc brake disc.

[0004] When the above equipment is in use, the convex heat-conducting block makes the temperature in the hollow cavity of the heat-conducting steel ring rise, and air convection is formed in the hollow cavity of the heat-conducting steel ring, which accelerates the entry of external cold air into the heat-conducting steel ring. At the same time, dust is easily accumulated inside the equipment in the later stage, thereby reducing the heat dissipation efficiency of the equipment in the later stage. Utility Model Content
