Hub-bearing assembly for a wheel of a motor vehicle

Abstract

A hub-bearing assembly includes a stationary radially outer ring, a flanged hub extending into an interior of the radially outer ring and configured to rotate relative to the radially outer ring, and a radially inner ring mounted on the flanged hub and axially abutting a portion of the flanged hub. A toothed sleeve is mounted to the hub axially inward of and adjacent to the radially inner ring and is rotationally fixed relative to the flanged hub. An auxiliary ring is mounted on the flanged hub in contact with the toothed sleeve. The flanged hub includes an axially inner rolled edge in contact with the auxiliary ring and configured to maintain a preload on the radially inner ring, and the auxiliary ring is configured to accommodate deformations induced by the formation of the rolled edge.
