By providing the heat dissipation channel 41 on the annular side wall of the main disk 1, and the heat dissipation channel 41 is evenly arranged on the main disk 1 along the circumferential direction, the heat generated by the main disk 1 during braking can be dissipated as soon as possible to prevent the heat from being transferred to the connecting disk 3, so as to avoid local gluing or local pitting of the connecting disk 3.

The processing precision is high and the manufacturing cost is low. By providing a heat dissipation channel 41 on the annular side wall of the main disk 1, and the heat dissipation channel 41 is evenly arranged on the main disk 1 along the circumferential direction, the heat generated by the main disk 1 during braking can be dissipated as soon as possible to prevent the heat from being transferred to the connecting disk 3, so as to avoid local bonding or local pitting of the connecting disk 3. In order to avoid the weakening of the strength of the heat dissipation channel 41, a reinforcing rod 42 is also provided in the heat dissipation channel 41. Through the cooperation of the above structure, the heat dissipation effect of the device is increased.
