Description

TECHNICAL FIELD

[0001] The utility model relates to the field of brake disc, especially to a brake disc ventilation and heat dissipation structure. BACKGROUND

[0002] The brake disc is a round plate, which rotates when the vehicle is running. The brake caliper clamps the brake disc to generate braking force. When the brake is pressed, it clamps the brake disc to slow down or stop the vehicle. The brake disc has good braking effect and is easier to maintain than the drum brake.

[0003] During the running of the vehicle, the brake disc rotates synchronously with the gear. During the braking of the vehicle, the friction between the brake disc and the caliper can reduce the speed. However, the brake disc that is always in friction with the caliper will continuously heat up. If the heat in the brake disc cannot be quickly dissipated, the long-term accumulation of heat will cause the brake disc to deform. Therefore, the brake disc needs regular maintenance. If deformation is found, the brake disc needs to be polished or replaced. Therefore, improving the heat dissipation performance of the brake disc can effectively improve the durability of the brake disc.

[0004] In related technologies, the traditional product does not have a ventilation structure on the head, and the scribe line on the brake disc of the traditional product does not penetrate the entire disc surface, resulting in poor heat dissipation effect of the entire product. There may be a phenomenon of heat decay of the brake disc, which affects the braking performance of the brake disc and reduces the safety of the vehicle.

[0005] Therefore, it is necessary to provide a brake disc ventilation and heat dissipation structure to solve the above technical problems. SUMMARY

[0006] The utility model provides a brake disc ventilation and heat dissipation structure, which solves the problem of poor heat dissipation effect.

[0007] To solve the above technical problems, the brake disc ventilation and heat dissipation structure provided by the utility model comprises a head, a brake disc ring, and a D-shaped head screw.

[0008] The brake disc ring is provided with a plurality of through scribe grooves arranged in a ring array, the through scribe grooves penetrate the disc surface of the brake disc ring, the head is provided with a plurality of head air guide grooves arranged in a ring array, the head is provided with a plurality of first mounting holes arranged in a ring array, the brake disc ring is provided with a plurality of second mounting holes arranged in a ring array, and the brake disc ring is provided with a plurality of air ducts arranged in a ring array.

[0009] Preferably, the head is installed on the brake disc ring through the D-shaped head screw passing through the first mounting hole and the second mounting hole, and the through scribe grooves are aligned with the head air guide grooves.

[0010] Preferably, the air guide groove of the closure is obliquely arranged, and the inner side of the air guide groove is narrow and the outer side is wide.

[0011] Preferably, a support block is fixedly connected to the inner surface of the brake disc rim, a positioning block is fixedly connected to the top of the support block, and a positioning hole is provided on the closing head.

[0012] Preferably, the positioning block is adapted to the positioning hole.

[0013] Compared with related technologies, the brake disc ventilation and heat dissipation structure provided by this utility model has the following beneficial effects:

[0014] This utility model provides a brake disc ventilation and heat dissipation structure. The air guide grooves at the closure end guide the airflow, ensuring that the air from the cooling duct is evenly directed towards the front of the brake disc, thus uniformly dissipating heat to both the inner and outer sides. The through-groove design allows for full connectivity between the inner and outer sides of the brake disc rim. The air from the air guide grooves blows outward along the through-groove, directly blowing away dust generated during brake pad friction, preventing it from accumulating on the brake pads. Firstly, this effectively improves the problem of decreased friction coefficient due to dust accumulation on the brake pads. Secondly, by removing dust and heat simultaneously, it alleviates brake fade caused by high temperatures, significantly reducing both the brake disc and brake pad temperatures, effectively balancing the wear rate on both sides of the brake disc.
