Abstract
Official abstract text for this publication.
A bearing-hub assembly having a rolling bearing provided with a stationary radially outer ring, at least one rotatable radially inner ring and at least one row of rolling bodies is provided. The bearing-hub assembly includes a light alloy hub, provided with a flanged portion and a cylindrical housing. The cylindrical housing is axially located inside the radially inner ring and is provided with an external lateral surface having a complementary shape with an internal lateral surface of the radially inner ring.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bearing-hub assembly comprising: a rolling bearing provided with a stationary radially outer ring, at least one rotatable radially inner ring and at least one row of rolling bodies, a light alloy hub, having a flanged portion and a cylindrical housing, axially located inside the radially inner ring and provided with an external lateral surface having a complementary shape with an internal lateral surface of the radially inner ring, and wherein along the internal lateral surface of the radially inner ring, a first plurality of annular grooves alternate between a first plurality of annular protrusions. 2. The bearing-hub assembly according to claim 1 , wherein along the external lateral surface of the hub a second plurality of annular grooves alternate between a second plurality of annular protrusions and in the first plurality of annular grooves of the radially inner ring the second plurality of annular protrusions of the hub are located, while in the second plurality of annular grooves of the hub the first plurality of annular protrusions of the radially inner ring are located. 3. The bearing-hub assembly according to claim 1 , wherein the at least one row of rolling bodies further comprises two rows of rolling bodies having pitch diameters (De, Di) of different size. 4. The bearing-hub assembly according to claim 1 , wherein the at least one row of rolling bodies further comprises at least first and second rows of rolling bodies, the bearing-hub assembly further comprising a first radially inner race of the first row of rolling bodies is formed integrated into the radially inner ring, wherein a second radially inner race of the second row of rolling bodies is formed on an annular insert, being part of the radially inner ring and integrated in the radially inner ring by a rolled edge, the rolled edge being located at an inner ring end and protruding radially towards outside and axially towards the annular insert.
