Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a combined brake disc structure. Background Art

[0002] As we all know, a brake disc is simply a round plate, which rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes.

[0003] In the prior art, brake discs made of cast iron have the advantages of strong durability and good corrosion resistance when in use, but they also have the disadvantage of being heavy, which increases the load of the vehicle; while brake discs made of carbon ceramics have the advantages of excellent heat dissipation performance and light weight, but they also have the problems of being not wear-resistant and requiring a high replacement frequency; in order to reduce the mass of the brake disc and minimize the friction loss of the brake disc, we propose a combined brake disc structure.

At the same time, the combination of the cast iron brake disc and the carbon ceramic brake block reduces the overall mass of the brake disc and effectively reduces the friction loss of the brake disc.

[0009] By adopting the above technical solution, after the connecting disc is tightly attached to one side of the cast iron brake disc, the threaded rod can penetrate the connecting disc, thereby facilitating the fixing of the cast iron brake disc.

[0010] Preferably, the outer side wall of the threaded rod is threadedly connected with a fixing nut.

[0011] By adopting the above technical solution, the fixing nut can be pressed tightly against the connecting disc by tightening the fixing nut on the threaded rod.
