Technical solution of the present utility model is: a kind of electric bicycle wheel hub structure, including outer wheel hub and inner wheel hub, it is provided with gripper shoe between described outer wheel hub and inner wheel hub, described gripper shoe includes matrix and multiple support former, described support former is distributed in flaabellum shape centered by matrix, the top of each described support former is provided with flanging, the outer of described gripper shoe is provided with in-flanges, described flanging and described in-flanges all with the perpendicular shape in face of described support former, and described flanging is in opposite direction with described in-flanges, described gripper shoe is connected to the inner side of described outer wheel hub by welding described flanging, and sealing wire is formed in the bottom of described flanging, the base of described sealing wire and described in-flanges encloses one sealing surface of self-assembling formation.
Further improvement of the utility model is: the quantity of described support former be five, in falling " convex " font, the end face of each described support former is equipped with reinforcement, described reinforcement is arranged on the centrage of described support former.
Further improvement of the utility model is: described outer wheel hub, described inner wheel hub and described gripper shoe all use cold-reduced sheet to make, use cold pressing forming process to carry out press-fiting combination between three, and the contact site between three carries out welding then one entirety of formation.
This utility model provides a kind of electric bicycle wheel hub structure, described support former is distributed in flaabellum shape centered by matrix, it is provided with flanging on the top of each described support former, it is provided with in-flanges in the outer of described gripper shoe, by welding described flanging, described gripper shoe is connected to the inner side of described outer wheel hub, and sealing wire is formed in the bottom of described flanging, the natural formation on the base of in-flanges of sealing wire utilizing weld is closed, and it is provided with reinforcement on described support former, improve intensity and the fastness of gripper shoe, and enhance its aesthetics, extend its service life.During producing stock layout, the stock layout of described gripper shoe uses the mode of concavo-convex splicing to carry out stock layout in the case of having reserved development size, largely decrease the waste of material, the whole circle subplate structure that compares use material amount, the stock utilization of this kind of mode stock layout can reach about 65%, greatly reduces cost.
The beneficial effects of the utility model are: this utility model provides a kind of electric bicycle wheel hub structure, its simple in construction, bearing capacity is strong, is provided with reinforcement, improves intensity and the fastness of gripper shoe, service life is extended, it in contrast to traditional former constructional appearance more aesthetically pleasing, and stock utilization is high, compares material-saving, greatly reduce cost, be worthy to be popularized.
