A motor vehicle wheel hub bearing and a method for mounting the bearing onto a motor vehicle suspension

摘要

A motor vehicle wheel hub bearing comprises an outer race (2) which can be mounted in a cylindrical seat (14) formed in a suspension strut (13) and fixed in the seat by cold rolling. The outer race has an outer cylindrical surface (18) adapted to be fitted into the seat (14). The cylindrical surface (18) extends over the whole axial dimension of the outer race (2) and has a greater axial dimension than that of the strut (13). The two axially opposite ends of the cylindrical surface (18) are constituted by respective axial tubular projections (19), (20) adapted to be deformed by cold forming radially outwardly towards respective opposite lateral surfaces (16, 12) of the strut (13) so as to fix the bearing to the strut.
