WHEEL BEARING FOR MOTOR VEHICLES

摘要

The invention relates to a wheel bearing for motor vehicles, substantially consisting of a multi-row angular contact bearing (1). Said multi-row angular contact bearing comprises an outer bearing ring (4) arranged in a hub (2) of a fastening flange (3) on the vehicle side and an inner bearing ring (7) arranged on a hub (5) of a fastening flange (6) on the wheel side, and a plurality of rolling elements (12, 13) that are disposed between the bearing rings (4, 7) one next to the other in at least two rows (8, 9) and that are held by at least two bearing cages (10, 11) interspaced in the peripheral direction at even distances. The rolling elements (12, 13) roll off in respective two adjacent groove-type races (16, 17 and 18, 19) that are machined into the inner face (14) of the outer bearing ring (4) and into the outer face (15) of the inner bearing ring (7), the contact angle axes (20, 21) thereof being pitched towards each other in an O arrangement and the races being axially delimited only on one side by respective shoulders (22, 23, 24, 25). The invention is characterized in that both the outer bearing ring (4) and the inner bearing ring (7) of the angular contact bearing (1) are one-piece and are completely integrated with its races (16, 17 and 18, 19) into the fastening flanges (3, 6) on the wheel and vehicle side, respectively, at least on row (8 or 9) of the rolling elements (12 or 13) being configured as balls. Said balls can be filled into the angular contact bearing (1) by axially inserting them into the clearance between the bearing rings (4, 7) and then tilting them into the races (17, 19).
