Abstract: For the purpose of facilitating correct fitting of a motor vehicle wheel onto a hub (10) which forms a central axial tubular projection (11) for insertion into a central wheel hole (30), a hub assembly comprises an annular cylindrical element (20) to be fitted on the projection (11) and having a plurality of circumferentially spaced resilient portions (21) capable of exerting force in radially outward directions on the wheel hole to support the wheel resiliently in an essentially centred manner relative to the hub.

Abstract: A hub for a motor vehicle wheel forms a central axial tubular projection with an outer cylindrical surface for inserting into a central hole through a wheel. An insert of non-oxidisable metal with a cylindrical portion is fixed to the cylindrical surface of the hub to cover this surface.

Abstract: A bearing-suspension standard assembly for a motor vehicle wheel comprises a standard (10) with an essentially cylindrical seat (11), and a bearing unit (12) with a non-rotating outer race (13) fixedly mounted in the seat (11). A cementing material (16) cooperates with the outer race (13) and the standard (10) so as to lock the bearing unit (12) in the seat (11)F.

Abstract: A bearing and suspension standard assembly for a wheel of a motor vehicle comprises a standard (10) with a cylindrical seat (11) in which there is formed at least one circumferential groove (111, 112), and a bearing (12) with a stationary outer race (13) mounted in the seat (11). The outer surface of the outer race (13) has at least a cylindrical side portion of smaller diameter (133) joined to a greater diameter portion (131) by means of an inclined surface (137) facing an inclined or concave portion (117) of the groove (111, 112). An annular fastening element (21) is inserted between the smaller diameter side portion (133) and the seat (11). The annular element (21) has an end portion (213) forcedly inserted between the inclined surface (137) of the bearing and the inclined or concave facing portion (117) of the groove (111, 112) so as to oppose relative movements between the bearing and the standard in at least one axial direction.
