Patent ID: 7862440

Claim:
A method of producing a nut assembly comprising a nut and a pressure plate non-releasably connected to each other so as to be rotatable relative to each other; said nut comprising: a drive portion for engaging a tool, a contact region for engaging the pressure plate, and an axially extending integral neck; said pressure plate comprising: an annular pressure plate body having an outer diameter and a central aperture into which the axially extending neck of the nut extends at least partially such that an extension of the neck partially overlaps or engages behind the pressure plate to form the non-releasable connection between the nut and the pressure plate, a felly contact region facing away from the nut, a contour which is radially expanded toward the felly contact region for mounting the pressure plate on the nut, a support surface provided for engaging the contact region of the nut, and a transition region between the support surface and the outer diameter; said method comprising forming the annular body, the outer diameter, the central aperture, the felly contact region, the radially expanded contour, the support surface, and the transition region of the pressure plate to final form in a single forming operation before assembly with the nut, wherein said single forming operation is a warm pressing operation which takes place in a multi-step sequence tool and includes a one-time heating process.
