However, the existing brake disc cooling rib structure has the problem that the temperature of the brake disc is increased due to untimely cooling. Temperature gradients and thermal stresses are formed during the heat dissipation process, thereby causing thermal fatigue cracking of the brake disc. Particularly in many long ramp lines, the heat dissipation performance of the brake disc is required to be higher.
