In addition, the brake disc with the full-floating connection structure comprises the brake disc body 100 and the fixed disc body 200, wherein the brake disc body 100 is connected with the fixed disc body 200 through the connecting frame 300, the middle part of the brake disc body 100 is provided with the mounting shaft hole 110 for mounting the fixed disc body 200, and the fixed disc body 200 is in clearance fit with the mounting shaft hole 110, so that the brake disc body 100 and the fixed disc body 200 can move relatively radially; the edge of the installation shaft hole 110 is provided with a plurality of uniformly distributed first bulges 120, a first notch 130 is formed between two adjacent first bulges 120, a plurality of second bulges 210 are arranged on the outer side of the fixed disc body 200, a second notch 220 is formed between two adjacent second bulges 210, the first bulges 120 are correspondingly arranged in the second notches 220, the second bulges 210 are correspondingly arranged in the first notches 130, and the thickness of the second bulges 210 is larger than that of the first bulges 120.

The first bracket 300a and the second bracket 300b of the connecting frame 300 are respectively disposed at two sides of the brake disc body 100 and the fixed disc body 200, so that the brake disc body 100 can perform bidirectional axial movement between the first bracket 300a and the second bracket 300 b. Specifically, the connecting frame 300 is provided with a plurality of spacing protruding blocks 310 and connecting protruding blocks 320 which are alternately distributed, the spacing protruding blocks 310 are arranged corresponding to the first protrusions 120, and the connecting protruding blocks 320 are connected with the second protrusions 210.

In the present embodiment, the fixed rotor 200 is clearance-fitted with the mounting shaft hole 110 by placing the fixed rotor 200 in the mounting shaft hole 110 so that the brake rotor 100 and the fixed rotor 200 can move radially with respect to each other. The second protrusions 210 and the second recesses 220 are respectively corresponding to the first recesses 130 and the first protrusions 120 of the brake disc body 100 one by one, and then the fixed disc body 200 and the brake disc body 100 are connected together through the mounting frame. Since the thickness of the second protrusion 210 is greater than that of the first protrusion 120, when the brake disc body 100 is connected with the fixed disc body 200 through the mounting bracket, a gap exists between the brake disc body 100 and the first and second brackets 300a and 300b, so that the brake disc body 100 can perform bidirectional axial movement between the first and second brackets 300a and 300 b. Therefore, when the brake disc body 100 is subjected to overheat deformation in the braking process, the brake disc body 100 has enough deformation floating travel and movement travel in the radial direction and the axial direction, so that the impact and vibration of the brake disc body 100 to the fixed disc body 200 can be effectively eliminated, the stability and the service life of the fixed disc body 200 are maintained, and the braking performance is guaranteed.
