Flanged bearing ring for the hub of a motor vehicle wheel

摘要

A flanged bearing ring has a tubular core of steel and an outer flange of a light metal in which there are formed axial through bores for accommodating bolts for mounting a wheel to the ring; fixed in each bore is a steel insert which forms a threaded inner cylindrical cavity extending between two opposite faces of the flange, and one or two transverse shoulders which are in contact with the material of the flange so as to oppose relative axial movements of the steel insert with respect to the flange.

1. A flanged bearing ring for a motor vehicle wheel, the flanged bearing ring defining a central axis of rotation and comprising:
a tubular core made of a first material comprised of a high toughness metal; a flange extending in a radially outer direction and comprised of a second material lighter than the first material, the flange being integral with the tubular core and having a plurality of axial through bores at positions equally angularly spaced from one another around the central axis of rotation, each of the axial through bores defining a respective axis parallel to the central axis of rotation; a plurality of steel inserts, each being fixed in one of the axial through bores and providing a threaded inner cylindrical cavity extending between an axially inner radial face of the flange and an axially outer radial face of the flange; and at least one first transversal outer surface extending transversely with respect to the central axis of rotation and in contact with the second material of the flange so as to counter relative axial movements of the plurality of steel inserts with respect to the flange.
