[0002] With the improvement of people's living standards, cars have gradually entered thousands of households, which has also promoted the rapid development of the automobile industry. As one of the main components in the automobile braking mechanism, the quality of the brake disc is closely related to the braking performance of the car. During the braking process of the car, the friction between the brake disc and the caliper is needed to drive the wheels connected to the brake disc to slow down.

Therefore, the brake disc must have good heat dissipation performance to ensure that the brake disc can cool down quickly and maintain stable performance. The brake discs currently on the market have a relatively simple structure, and heat dissipation is slow during braking, affecting braking performance. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figures 1 to 3 The utility model provides a combined heat dissipation brake disc: it includes a brake disc 1 and a brake disc 2 5 connected to each other, a plurality of equidistantly distributed internal threaded tubes 7 are axially fixed to the end surface of the brake disc 2 5, each internal threaded tube 7 is connected to a bolt 4, the brake disc 1 is connected to the brake disc 2 5 through the bolt 4, the outer surface of the brake disc 1 axially penetrates a plurality of equidistantly distributed countersunk holes 3, the small-diameter end of each countersunk hole 3 is sleeved with an internal threaded tube 7, each countersunk hole 3 is penetrated by a bolt 4, the outer surfaces of the brake disc 1 and the brake disc 2 5 are axially penetrated by a plurality of equidistantly distributed heat dissipation holes 2, and a plurality of equidistantly distributed blades 6 are connected in the middle of the brake disc 1 and the brake disc 2 5. The end faces of 6 are horizontally penetrated by multiple equally spaced countersunk holes 28, and each countersunk hole 28 is movably connected to an internal threaded tube 29. Each internal threaded tube 29 is axially fixed to the end face of the brake disc 25. Each countersunk hole 28 is provided with a bolt 210, and the end of the bolt 210 is threadedly connected to the internal threaded tube 29. The inner side of the brake disc 1 is axially provided with multiple equally spaced blind holes 11, and each blind hole 11 is inserted with a bolt 210. Each blade 6 is horizontally penetrated by multiple equally spaced heat dissipation holes 212. The blade 6 is made of an iron-based high-temperature alloy. The inside of the brake disc 1, the inner side of the brake disc 25 and the outside of the blade 6 are coated with heat dissipation paint, and the outside of the brake disc 1 is coated with a heat-sensitive pigment layer.

[0021] By connecting a plurality of equally spaced blades 6 between the brake disc 1 and the brake disc 2 5, a heat dissipation hole 12 is provided on the surface of the brake disc 1 and the brake disc 2 5, and a heat dissipation hole 2 12 is provided on the outer side of the blade 6, so that when the brake disc rotates, the blade 6 is driven to rotate. When the blade 6 rotates, wind force is generated, and the wind force is used to dissipate the high temperature generated by the brake disc during braking.

When the blade 6 rotates, wind force will be generated, and the wind force will be used to dissipate the high temperature generated by the brake disc during braking. At the same time, Sack 1 dissipates heat for the entire brake disc, and the heat dissipation holes 2 12 further cool down the blade 6 to prevent the blade 6 from accumulating excessively high temperature on the brake disc, which will affect the wind temperature when the blade 6 rotates, thereby ensuring the cooling effect of the blade 6 on the brake disc. Providing a heat dissipation coating on the outside of the blade 6 further improves the heat dissipation efficiency of the brake disc. When the blade 6 is damaged When replacement is needed, first take out bolt 4, remove brake disc 1 from blade 6, then find the damaged blade 6, remove bolt 2 10 on blade 6, pull out the damaged bolt 2 10 from the outside of internal threaded tube 2 9, replace with a new blade 6, and then install bolt 2 10 back into internal threaded tube 2 9, then install brake disc 1 back onto blade 6 so that internal threaded tube 7 is inserted into countersunk hole 3, and then fix it with bolt 4.
