BEARING ARRANGEMENT FOR A HUB OF A VEHICLE

摘要

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 two radial rolling bearings (2, 3) and two axial rolling bearings (4, 5) to support a first vehicle part (6) such as a wheel hub relatively to a second vehicle part (7) such as a flanged outer ring. Each rolling bearing (2, 3, 4, 5) has a first raceway (2', 3', 4', 5') and a second raceway (2", 3", 4", 5") for rolling elements (2"', 3"', 4'", 5"') located between the respective raceways. A first auxiliary ring (8) is firmly connected, e.g. press fitted, with the first vehicle part (6) and a second auxiliary ring (9) is mounted to the second vehicle part (7), e.g. by deformation of a part (10) of the second vehicle part (7). The first raceways (2', 3') of the two radial rolling bearings (2, 3) are machined directly into the first vehicle part (6). The first auxiliary ring (8) has the first raceways (4', 5') of the two axial rolling bearings (4, 5). The second raceways (2", 4") of the first radial rolling bearing (2) and the first axial rolling bearing (4) are machined directly into the second vehicle part (7). The second auxiliary ring (9) has the second raceways (3" 5") of the second radial rolling bearing (3) and the second axial rolling bearing (5). The two radial rolling bearings (2, 3) are e.g. cylindrical roller bearings and the two axial rolling bearings (4, 5) are e.g. thrust ball bearings having a larger pitch circle diameter than the cylindrical roller bearings.
