<p>The invention relates to a rolling bearing arrangement (1) for a hub of a vehicle wheel. To minimize the friction of the bearing when using a bearing arrangement of this type the rolling bearing arrangement (1) comprises three rolling bearings (2, 3, 6) to support a first vehicle part (4) such as a wheel hub relatively to a second vehicle part (5) such as a flanged outer ring. Each rolling bearing (2, 3) comprises a first raceway (2', 3', 6') and a second raceway (2", 3", 6") for rolling elements (2"', 3"', 6"') located between the respective raceways. The first rolling bearing (2) is an angular contact ball bearing (ACBB). The first raceway (2') of the angular contact ball bearing (2) and the first raceway (3') of the second rolling bearing (3) are machined directly into the first vehicle part (4) and the second raceway (2") of the angular contact ball bearing (2) and the second raceway (3") of the second rolling bearing (3) are machined directly into the second vehicle part (5). The first raceway (6') of the third rolling bearing (6) is machined directly into a face side (7) of the second vehicle part (5) and the second raceway (6") of the third rolling bearing (6) is arranged at or in an auxiliary ring (8) which is connected with the first vehicle part (4). The second rolling bearing (3) is e.g. a cylindrical roller bearing and the third rolling bearing (6) is e.g. a thrust ball bearing having a larger pitch circle diameter than the cylindrical roller bearing.</p> |
