The patent abstract shows that the present invention relates to the field of brake disc technology, specifically to brake discs and brake disc manufacturing processes, comprising a brake disc body. The outer wall of the top of the brake disc body is provided with a T-shaped groove, and the internal fixed connection of the T-shaped groove is a fixed rod. The internal rotation connection of the T-shaped groove is an upper disc body, and the outer wall of the bottom of the upper disc body is fixedly connected to a movable rod. The outer walls of multiple movable rods are slidably connected to the internal of the T-shaped groove. The outer wall of one side of multiple fixed rods is provided with a buffering mechanism. The compression force generated by the housing movement on the buffer spring can cause deformation, absorption, and energy storage of the buffer spring, thereby buffering the impact force received by the T-shaped groove, avoiding the sudden braking of the T-shaped groove, which will increase the wear of the T-shaped groove and increase the impact force on passengers inside the vehicle. Correspondingly, buffering the T-shaped groove reduces the impact force generated during emergency braking, while improving the stability of the braking system and passenger comfort.
