MOUNTING OF A WHEEL-HUB BEARING ON A MOTOR-VEHICLE SUSPENSION

摘要

The outer ring (3) of a motor-vehicle wheel-hub bearing (1) is housed in a cylindrical seat (9) of a strut (10) and is locked axially, on one side of the strut (10), by means of a radially inwardly-projecting rim (18) formed by cold deformation of a tubular portion (17) of the seat (9) and, on the other side, by means of a shoulder (11). A resiliently compressible ring (19) is inserted into the seat (9) of the strut (10) so as to be compressed axially between a lateral surface (12, 13) of the outer ring (3) of the bearing and the shoulder (11) or the deformed rim (18) of the seat (9), respectively, to compensate for any relative thermal expansion between the bearing and the seat.
