TECHNICAL FIELD

[0001] The utility model relates to brake disc technical field, concretely relates to a drum brake disc of assembly. BACKGROUND

[0002] Brake disc, simply speaking, is a round dish, and it is also rotating when the car is running. The brake caliper clamps the brake disc to generate braking force, and it clamps the brake disc to play the role of deceleration or parking when the brake is pressed. The brake disc has good braking effect, and is easier to maintain than the drum brake. There are disc brakes and drum brakes, and air brakes. Many older cars are front disc and rear drum, and many cars are front and rear disc brakes. The disc brake is better than the drum brake in heat dissipation, and is not easy to produce heat recession in high-speed braking state, so the high-speed braking effect is good. But in the low-speed cold brake, the braking effect is not as good as the drum brake, and the price is higher than the drum brake. Therefore, many medium and high-grade cars adopt full disc brake, and ordinary cars adopt front disc and rear drum. Relative to low speed, and the truck and bus that need braking force still adopt drum brake.

[0003] But the existing brake disc body in the process of rotating, because the airflow in the heat dissipation hole cannot form a more effective flow with the outside airflow, so that the heat in the heat dissipation hole cannot be more effective, the heat dissipation is slow. To solve the above problems, the utility model discloses a kind of heat dissipation brake disc including brake disc body and heat dissipation component, the inner side surface of the brake disc body is provided with heat dissipation component, the heat dissipation component includes flow guide plate, flow guide groove, heat dissipation hole, first heat dissipation groove, arc part, wind baffle, connecting plate and second heat dissipation groove, the inner side surface of the brake disc body is integrally formed with flow guide plate.
