Wheel bearing unit and method for producing the same

摘要

The invention relates to a wheel bearing unit (1) for a vehicle wheel, comprising a hub element (2, 3, 2′) which has an axially (a) extending cylindrical section (4) to be supported by a bearing arrangement (5) and which has a radially (r) extending flange section (6) for fixing the vehicle wheel and/or a brake disk at a face side (7) of the flange section (6), wherein the bearing arrangement (5) has an outer ring (8). To ensure a firm and cost effective axial connection between the hub element and the outer ring, the invention is characterized in that the outer ring (8) has a radially extending insection (9) at its a outer circumference (10), wherein the axially (a) extending cylindrical section (4) of the hub element (2, 3, 2′) is deformed partially (11) so that a section of it interferes in the insection (9) for axially fixing the hub element (2, 3, 2′) relatively to the outer ring (8). The invention also relates to a method for producing a wheel bearing unit.

1. Wheel bearing unit for a vehicle wheel, comprising:
a hub element which has an axially extending cylindrical section to be supported by a bearing arrangement and which has a radially extending flange section configured to fix the vehicle wheel and/or a brake disk at a face side of the radially extending flange section, the bearing arrangement having an outer ring, the outer ring has a radially extending depression in an outer surface along an outer circumference thereof, wherein the axially extending cylindrical section of the hub element is deformed partially so that a section thereof is positioned in and engages the depression for axially fixing the hub element relative to the outer ring, the axially extending section of the hub element has an axial end located on a side of the radially extending depression opposite from the radially extending flange section of the hub element, wherein the outer ring extends axially past the axial end of the hub element such that a portion of the outer surface of the outer ring is not enclosed by the hub element.
