Patent ID: 7874732

Claim:
A drive wheel support bearing assembly which comprises: a hub axle, a constant velocity universal joint and a bearing unit which are unitized together; an inner member including an outer coupling member of the constant velocity universal joint and the hub axle mounted on an outer periphery of a hollow stem portion of the outer coupling member, one of double row inner peripheral side raceway surfaces of the bearing assembly being formed on the hub axle while the other of the inner peripheral side raceway surfaces is formed on the outer coupling member; an outer member having double row outer peripheral side raceway surfaces formed therein; rolling elements interposed between the raceway surfaces that radially confront to each other; hardened indentations formed in an inner periphery of the hub axle, the hub axle and the outer coupling member being 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 of the outer coupling member, to allow the hollow stem portion to bite into the indentations to crimp; and detecting device provided in the outer member for detecting a displacement or deformation of the outer coupling member of the constant velocity universal joint and a displacement or deformation of the hub axle.
