Hub sleeve formed of deep-drawn parts

摘要

A hub for a bicycle or the like consists of two coaxial sleeve members secured together against relative axial and rotational movement. Each sleeve has an outwardly extending spoke flange disposed transversely of the hub axis. One sleeve member is cylindrically shaped and has an axial length approximately the same as the hub. The other sleeve member is cup-shaped and fits over one end of the cylindrical-shaped sleeve member. The two sleeve members are deep-drawn parts. The sleeve members can be secured together in various ways such as mechanical interconnection, welding or by an adhesive material.
