A shortcoming of the aforementioned patent is that the mounting inner disc and the friction outer disc member of the brake disc are connected and fixed by a plurality of threaded rods or plug pins, requiring individual manipulation at each connection point during installation, which is complex and cumbersome, and results in low assembly efficiency.

[0004] In summary, there is a need for a brake disc structure that is easy to install, simple to operate, and has high assembly efficiency. Utility Model Content

[0005] The utility model is designed to overcome the shortcomings of the prior art in which the inner disc and the friction outer disc of the brake disc are connected and fixed by a plurality of threaded rods or plug pins, and each connection position needs to be operated one by one during installation, which is complicated and tedious to operate and has low work efficiency. The utility model provides a brake disc structure that is easy to install, simple to operate and has high assembly efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A brake disc structure comprises an inner disc, an outer disc and a retaining spring, the outer diameter of the inner disc and the inner diameter of the outer disc matching each other, a plurality of placement grooves being provided on the disc surface of the inner disc, the placement grooves being arranged in a ring shape at the outer edge of the inner disc, a connecting block matching the placement grooves being fixed on the inner ring wall of the outer disc, the outer disc being connected by the cooperation of the connecting block and the placement grooves, a plurality of limit blocks being fixed on the disc surface of the inner disc, the limit blocks and the placement grooves being located on the same surface of the inner disc, the limit blocks being arranged in a ring shape at the outer edge of the inner disc, the limit blocks being located on the side of the placement grooves, the limit blocks being provided with limit grooves, all of the limit grooves together forming an annular retaining groove matching the retaining spring, the annular retaining groove and the placement grooves being located on the same annular contour, the retaining spring and the annular retaining groove being socketed with each other.

[0008] During installation, the placement grooves on the inner disc are aligned with the connecting blocks on the outer disc. The inner and outer discs are assembled together by fitting the placement grooves and connecting blocks together. The retaining spring is then installed into the annular retaining groove formed by all the limiting grooves. This allows the connecting blocks within the placement grooves to be positioned and fixed, thus completing the assembly and fixation between the inner and outer discs. This makes installation easy, simple, and efficient. Furthermore, the retaining spring's inherent elasticity can buffer the force transmitted between the inner and outer discs during vehicle movement or braking, thus protecting components.

[0009] Preferably, the limiting blocks and placement slots are alternately arranged on the surface of the inner disk. By alternating the limiting blocks and placement slots, the retaining spring can more comprehensively and evenly position and fix the connecting blocks in the placement slots, thereby improving the fixing effect and enhancing the structural stability.

[0010] Preferably, the stop block is L-shaped, with one side end of the stop block fixed to the inner disk surface, and the other side end of the stop block facing the central axis of the inner disk. The stop slot is formed by the stop block and the inner disk surface. The stop block has a simple structure, is easy to manufacture, and has low production cost.

[0011] Preferably, the connection block and the outer disk, and the limit block and the inner disk are fixed by welding, which has a good fixing effect.

[0012] Preferably, the shape of the retaining spring is a cylindrical spiral. The cylindrical spiral retaining spring design facilitates the retaining spring to be installed in the annular retaining groove, and on the other hand, ensures a good limiting effect of the retaining spring while also providing a certain buffering capacity for the force transmission between the inner and outer discs.

[0013] Preferably, the inner disc is provided with a plurality of hollow holes, through which the external airflow can repeatedly pass through the inner disc through the hollow holes, thereby improving the heat dissipation effect of the brake disc.

[0014] The beneficial effects of the utility model are: easy installation, simple operation, high assembly efficiency; it has the function of protecting parts; it improves the fixing effect and enhances the structural stability; it has a simple structure, is easy to process, and has low production cost; and it improves the heat dissipation effect.
