摘要

A wheel support unit is constituted by a rolling bearing whose rings have attachment flanges respectively for a wheel and for a vehicle suspension and a constant velocity joint fixed for rotation with the ring provided with the attachment flange for the wheel; this ring is constituted by two sleeve-shaped half-rings fitted together coaxially, a first on a second, the first half-ring being formed integrally at one end with the wheel attachment flange and the second half-ring being formed integrally at its opposite end with a bell housing for the constant velocity joint, which is formed as an independent unit composed of two rings mounted concentrically with the interposition of rolling bodies; the joint being an interference fit in the bell and the two half-rings being an interference fit with each other and the respective parts being fixed together by welding.
