A mounting hole 33 is provided at the bottom of the lower brake disc 2 to fix the lower brake disc 2 to the bottom end of the upper brake disc 1. A mounting bolt 34 is provided on the inner wall of the mounting hole 33. The outer wall at the top of the mounting bolt 34 is threadedly connected to the inner wall at the bottom end of the upper brake disc 1. The stability between the upper brake disc 1 and the lower brake disc 2 is further improved by the mounting bolt 34. The bottom end of the upper brake disc 1 close to the outer side of the lower brake disc 2 is fixed. A locating pin 35 is connected for limiting the position of the upper brake disc 1 and the lower brake disc 2 when they are installed. A locating hole 36 is opened at the top outer side of the lower brake disc 2. The outer wall of the bottom end of the locating pin 35 slides on the inner wall of the locating hole 36. Through the coordinated use of the locating pin 35 and the locating hole 36, the upper brake disc 1 and the lower brake disc 2 can be quickly positioned, thereby improving the installation efficiency of the upper brake disc 1 and the lower brake disc 2. At the same time, the locating pin 35 and the locating hole 36 can further improve the firmness and stability between the upper brake disc 1 and the lower brake disc 2.

[0031] Reference Figure 2 and Figure 3The cross-sections of the upper brake disc 1 and the lower brake disc 2 are both set to an L shape, which can provide better support and deformation resistance in different directions, while increasing the contact area between the brake disc and the air, which helps to dissipate heat faster and improve the heat dissipation efficiency of the brake system. There are multiple groups of mounting holes 1 31 and mounting holes 2 33, and the multiple groups of mounting holes 1 31 and mounting holes 2 33 are arranged in a circular array on the center line of the brake disc 1 and the lower brake disc 2, which enhances the stability of the connection between the upper brake disc 1 and the lower brake disc 2.

Multiple groups of locating pins 35 are provided, and the multiple groups of locating pins 35 are respectively arranged on both sides of the mounting hole 31. The multiple groups of locating pins 35 can more accurately realize the positioning of the upper brake disc 1 and the lower brake disc 2. During the installation process, multiple positioning points can more accurately guide the alignment of the two brake discs, reduce installation deviation, and improve installation accuracy and efficiency. At the same time, the locating pins 35 distributed on both sides of the mounting hole 31 can enhance the stability after installation, and effectively reduce the deformation and loosening of the brake disc during operation.

[0032] Reference Figure 2 - Figure 4 A heat dissipation component is provided on the inner walls of the upper brake disc 1 and the lower brake disc 2, and the heat dissipation component includes a heat dissipation hole 41, and the heat dissipation hole 41 is opened through the top of the upper brake disc 1, and the heat dissipation hole 2 is opened through the bottom of the lower brake disc 2.

A notch 2 44 is provided in the shorter portion of the L shape of the upper brake disc 1, and a notch 1 43 is provided in the shorter portion of the L shape of the lower brake disc 2, which can reduce the weight of the brake disc, and a through groove is provided in the middle portion where the upper brake disc 1 and the lower brake disc 2 are connected, and the through groove is connected with the notch 1 43 and the notch 2 44, which helps to optimize the flow of air inside the brake disc and further improve the heat dissipation efficiency.

[0033] Working principle: When in use, when the upper brake disc 1 and the lower brake disc 2 are assembled and installed, the locating pin 35 at the bottom of the upper brake disc 1 is first inserted into the locating hole 36 at the top of the lower brake disc 2, which can quickly and accurately achieve positioning, reduce installation deviation, and improve installation accuracy and efficiency. At the same time, multiple groups of locating pins 35 are distributed on both sides of the installation hole 31, which enhances the stability after installation and effectively reduces the deformation and loosening of the brake disc during operation.

[0034] At this time, the upper brake disc 1 and the lower brake disc 2 are firmly connected by the mounting bolt 1 32 in the mounting hole 1 31 and the mounting bolt 2 34 in the mounting hole 2 33. The plurality of mounting holes are distributed in a circular array to disperse the stress and impact force generated during braking, making the combination of the two more stable and reliable, and reducing the risk of loosening or separation that may occur during high-intensity braking operations.

[0035] During use, the L-shaped design of the upper brake disc 1 and the lower brake disc 2 increases the contact area with the air, which helps to dissipate heat faster. At the same time, the heat dissipation hole 41 running through the top of the upper brake disc 1 and the heat dissipation hole 42 running through the bottom of the lower brake disc 2, as well as the notch 44 of the upper brake disc 1, the notch 43 of the lower brake disc 2 and the through groove connecting the two in the middle, together constitute an efficient heat dissipation channel, which optimizes the flow of air inside the brake disc, further enhances the heat dissipation effect, reduces the temperature rise of the brake disc, reduces the risk of thermal attenuation, and ensures the stability of braking performance.
