Abstract
A wheel hub includes a wheel rim and a support. The wheel rim has an inner rim surface, an outer rim surface and a connection concave. The wheel rim is composed of a metallic layer and a carbon fiber layer. The outer rim surface has an outer wall to be the metallic layer. The wheel hub is composed of the metallic layer and the carbon fiber layer. Compared to the conventional wheel hub made of a single metallic material or a carbon fiber material, the wheel hub made of metal and carbon fiber of the present invention is light in weight, endurable, and cost-effective. The outer wall of the outer rim surface of the conventional wheel hub is easily to be damaged by an external force when in use, which result in a break of the carbon fiber to lose the strength of the carbon fiber. By contrast, the present invention has the metallic layer to protect the outer wall of the outer rim surface of the wheel rim, so that the carbon fiber layer of the wheel rim won't be hit by an external force so as to enhance the quality of the wheel hub.
