<p>The invention relates to an interchangeable wheel bearing unit (3), for example for commercial vehicles, comprising a wheel hub (2) and two tapered roller bearings (1, 1'), each having an outer ring (4, 4') and an inner ring (5, 5'), between which a respective row of tapered rollers (6) is situated, and a securing ring (8) in at least one of the inner rings (5, 5') of the tapered roller bearing (1, 1'). The aim of the invention is to assemble said wheel bearing unit (3) without specialist knowledge and special tools, using simple tools that are available in garages, without a specific requirement for cleanliness during the assembly process. To achieve this, each outer ring (4, 4') of the tapered roller bearings (1, 1') has a cylindrical extension (10), which runs coaxially with the wheel hub axis (9) towards the outer face of the bearing and into which a respective seal (12, 12') is inserted, and a retaining element (13, 13'), which is supported on the corresponding inner ring (5, 5') and axially fixes the outer ring (4, 4'), is located on the opposite face of the respective tapered roller bearing (1, 1') from the seal (12, 12'). ® KIPO & WIPO 2009</p> |
