Abstract
A hybrid connection element, in particular a bearing outer element of a wheel bearing, includes a core part made of steel and a reinforcement part made of plastic. The reinforcement part at least partially encases the core part. The core part includes a hollow cylindrical bearing unit extending in an axial direction and a flange extending in a radial direction. The reinforcement part includes at least one reinforcement rib which transmits force between the bearing unit and the flange of the core part.
Claims12
A hybrid connection element, in particular a bearing outer element of a wheel bearing for securing a vehicle wheel,
- having a core part made of a first material, and
- a reinforcement part made of a second material, which at least partly encases and thus reinforces the core part,
- wherein the core part comprises a hollow cylindrical bearing unit for forming a rolling bearing, which extends in an axial direction,
- wherein the core part comprises a flange, which extends in a radial direction from one axial end of the bearing unit,
- wherein the reinforcement part comprises at least one reinforcement rib, which transmits forces between the bearing unit and the flange of the core part,
- wherein the at least one reinforcement rib comprises two reinforcing ribs that bridge a weight-reduction aperture in the flange in the radial direction in order to transmit forces across the aperture by means of the reinforcement part, and
- wherein the at least one reinforcement rib is of hollow design in order to save weight.
A hybrid bearing outer element of a wheel bearing comprising:
- a core part, made of a first material, having a hollow cylindrical bearing unit which extends in an axial direction and a flange which extends in a radial direction from one axial end of the bearing unit;
- and
- a reinforcement part made of a second material, at least partially encasing the core part and having multiple hollow reinforcing ribs extending across a weight reduction aperture of the core part in the radial direction.
