Abstract
A hub for a motor vehicle wheel provides a cylindrical portion that extends in an axial direction, and a flange extending in a radially outer direction from an axially outer end of the cylindrical portion. The hub includes a core of metallic material which extends into the cylindrical portion and in the flange of the hub, and a covering body of plastic material applied over the core.
Claims14
A hub for a motor vehicle wheel, the hub comprising:
- a cylindrical portion that extends in an axial direction, and
- a flange extending in a radially outer direction from an axially outer end of the cylindrical portion, wherein
- the hub includes a core of metallic material that extends into the cylindrical portion and in the flange of the hub, and a covering body of plastic material applied over the core;
- wherein
- the core forms, as a single piece, a cylindrical core portion that extends in the axial direction and a core flange that extends in a radially outer direction from an axially outer end of the cylindrical core portion, the cylindrical core portion and the core flange defining the cylindrical portion and the flange of the hub, respectively;
- and wherein
- wheel mounting holes are formed through the core flange, and
- wherein the core flange is star shaped and is formed by a plurality of spokes uniformly arranged around a central rotation axis (x) of the hub and extend radially outwardly from the axially outer end of the cylindrical core portion, and
- wherein the spokes are circumferentially separated by gaps, and wherein the covering body substantially fills the gaps.
