Description

Technical Field

[0001] The utility model relates to an aluminum-carbon hub structure and belongs to the technical field of hubs. Background Art

[0002] The hub is one of the key parts of a bicycle. It is located at both ends of the axle and is mainly used to fix the wheels on the bicycle. Its main function is to transfer the power of the bicycle to the wheels so that they can rotate. The hub is usually composed of two parts: the shell and the bearing. The shell is responsible for protecting the bearing and fixing it to the wheel, while the bearing is responsible for supporting the wheel and providing smooth movement during riding.

[0003] The existing hubs on the market all have aluminum alloy shells, or aluminum alloy shells with a piece of carbon fiber wrapped in the middle, which are relatively heavy, and the existing aluminum alloy shell processing technology is very complicated. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an aluminum-carbon hub structure, which combines carbon fiber prepreg cloth and aluminum alloy blades together and is formed into an integrated hub structure through mold heating, thereby reducing the complicated process of aluminum alloy shell processing, enhancing the strength of the hub shell, and reducing the weight of the hub.

[0005] The utility model is realized through the following scheme: an aluminum-carbon hub structure, which includes a shell and a spoke connecting seat, the shell is a cylindrical structure, a spoke connecting seat is connected to both ends of the shell, the spoke connecting seat is a circular structure, blades are connected to the outer wall of the spoke connecting seat, and through holes are opened on the blades.

[0006] The shell is made of carbon fiber.

[0007] The shell, the spoke connecting seat and the blades are integrally formed.

[0008] The spoke connecting seat and the blades are both made of aluminum alloy.

[0009] The number of the blades is 4, 5, 6 or 7, and the blades are evenly distributed on the outer wall of the spoke connecting seat.

[0010] The beneficial effects of the utility model are:
