[0027] When the brake disc is working, the first brake disc body 1 and the second brake disc body 2 are guided to dissipate heat through the axial ventilation path and radial heat dissipation groove of the heat dissipation structure 3. The heat dissipation holes 62 and guide plates 63 of the partition column 6 drive the lateral airflow through the airflow channel 7 to be discharged outward. The heat dissipation holes 44, heat dissipation grooves 45 and fin groups 47 dissipate the heat of the hub part 4.

[0029] The heat dissipation structure 3 forms an axial ventilation path through the first ventilation port 31 and the second ventilation port 32. Combined with the radial diffusion groove design of the first heat dissipation groove 33 and the second heat dissipation groove 34, it realizes multi-directional airflow when the brake disc rotates, accelerates the outward diffusion of heat, and can also increase the contact area with air through the groove structure.

[0037] The main body 61 of the partition column establishes a transverse airflow channel between the disks through the heat dissipation holes 62. Combined with the spiral distribution of the airflow guide plate 63, it forms a guiding effect, promotes airflow through the heat dissipation holes 62 and the airflow channel 7, and increases the heat dissipation efficiency.
[0038] The working principle of the high heat dissipation brake disc provided by this utility model is as follows:
[0039] When the brake disc is working, the first brake disc body 1 and the second brake disc body 2 are guided to dissipate heat through the axial ventilation path and radial heat dissipation groove of the heat dissipation structure 3.

The fixing part 54 and positioning groove 53 of the connecting part 5 maintain the structural stability. Rapid heat dissipation is achieved through multi-stage heat dissipation paths and optimized structure.
[0040] Compared with related technologies, the high heat dissipation performance brake disc provided by this utility model has the following beneficial effects:
[0041] The first brake disc body 1 and the second brake disc body 2 form a double-layer heat dissipation system with the heat dissipation structure 3 and the partition column 6, so that the high-temperature airflow is discharged to the outside through the airflow channel 7; the wheel hub 4 reduces weight while ensuring strength, and the ventilation hole 44, the third heat dissipation groove 45 and the heat dissipation fin group 47 increase the heat dissipation capacity of the wheel hub 4, so as to achieve efficient heat dissipation, structural stability and lightweight as a whole.
