The invention relates to a combined hub and belongs to the technical field of hubs. The combined hub comprises a rim; the rim is of a hollow cylinder structure; a round ring is arranged inside the rim and welded to the rim; the rim is further connected with a spoke; the spoke is of a round board structure; a center hole is formed in the center of the spoke; the spoke is provided with multiple connection through holes; the connection through holes are evenly distributed in the spoke; a U-type groove is formed in the bottom of the spoke. The combined hub has the beneficial effects that the rim is connected with the spoke through bolts, the structure that a rim and a spoke of a traditional hub are integrated is changed, the rim and the spoke which are manufactured through spinning and other methods are high in strength and light in weight, the hub is easy to detach due to the bolt connection method, and if one component is damaged, the damaged component can be replaced conveniently. The combined hub is exquisite in design, reasonable in structure, unique in method and low in cost, and reduces the process difficulty of the hub.
