ABSTRACT:
A drive wheel support bearing assembly includes a hub axle, a constant velocity joint and a bearing unit which are unitized together, and an inner member made up of an outer coupling member of the CVT with the hub axle mounted on an outer periphery of a hollow stem portion of the outer coupling member. Inner peripheral side raceway surfaces are formed on the hub axle and the outer coupling member. Hardened indentations are formed in an inner periphery of the hub axle, and the hub axle and the outer coupling member are plastically coupled integrally with each other by radially outwardly expanding a mounting area, at which the hub axle is mounted on the hollow stem portion, to allow it to bite into the indentations to crimp. Sensors for detecting the displacement or deformation of the outer coupling member and the hub axle are provided in the outer member.
