<p>A hub bearing assembly for a motor vehicle wheel comprises a flanged ring (10) and a set of pin connection elements (20). The flanged ring (10) defines a central axis of rotation (x) and comprises a tubular core (15) made of steel and an outer flange (11) of light metallic material in which axial through bores (12) are formed. The pin connection elements (20) each have a head portion (22), an axial cylindrical shank portion (21) which defines a respective longitudinal axis (y) parallel to the axis of rotation (x) and is accommodated in one of the bores (12), and a threaded cylindrical surface (24) for connecting the flanged ring (10) to a wheel or to a suspension standard of the vehicle. The shape of each head portion (22) is different from that of a solid of revolution generated about the longitudinal axis (y) of the shank portion (21). Each head portion (22) is accommodated in a respective recess (16) of corresponding shape, formed in one (13) of the two radial opposite faces of the flange (11).</p> |
