Abstract: Sealing device (1) with a sensor for a rolling bearing (2), in which the sealing shield (7) is mounted between two races of the rolling bearing (2), and a encoder wheel (8) is arranged inside the rolling bearing (2) between the two races and the shield (7); a detecting (9) sensor being arranged inside a housing (10) which is obtained through the shield (7) and which is also arranged with a respective detecting surface which directly faces the encoder wheel (8).

Abstract: In a vehicle wheel hub bearing unit and brake arrangement, the bearing forms a rotating radial flange (11) adapted for securing to a radial flange (12) of a brake member and rotate fixedly therewith. The brake member flange (12) is located substantially in the same radial plane of the bearing flange (11) and secured directly to the peripheral portion thereof. A form or splined connection (13, 14) couples the flanges (11, 12) in non-rotatable manner. The hub bearing flange (11) has a shoulder (15, 135) radially protruding from the axially inner side thereof so as to provide an axially inner abutment for the brake member flange (12). The brake member flange (12) is axially restrained from axial outward motion by the wheel rim (16, 21).

Abstract: There is disclosed a method of mounting a wheel hub bearing assembly to the knuckle (10) of a vehicle suspension standard by forcefully inserting the outer race (20) of the bearing in a bore (11) in the knuckle (10). The bore has a groove (15) near its axially outer side to accommodate a snap ring (14) for axially securing the bearing's outer race (20) within the bore (11). Angularly spaced radial slots (24) are provided in the axially outer rim of the knuckle (10); a hub bearing unit is assembled separately. The snap ring (14, 14') is fitted over the hub at an axial location between the axially outer end portion (23) of the bearing outer race (20) and a portion (34) of the hub (16) facing said end portion (23); at least one axially tapered sliding surface (33, 34, 23) is provided between said facing portions (23, 34).

Abstract: There is disclosed a wheel hub or hub unit of the type having a radial hub flange (13) providing connection to the wheel (40) and to a brake member (10) having an annular disc portion having a plurality of ears (11) radially protruding from its inner edge. The hub flange (13) defines a plurality of axial passages, in the form of peripheral radial recesses (19) or bores (17, 17') for slipping a plurality of axial pins (30) to be fitted in holes (12) obtained in the brake member ears (11) and in openings (22) obtained in at least one radial wall (23) of a brake carrier (20) rotatably fast with the hub (14) to rotationally secure the brake member (10) to the hub. When the wheel (40) is mounted on the outside of the hub flange, axial movement of the pins towards the outside is stopped by the wheel.

Abstract: A vehicle wheel hub bearing unit is disclosed, in which the outer race (10) of the bearing has a radial bearing flange (11) providing an axially protruding edge (12) adapted for being folded by rolling in a radially outer direction to secure for rotation a flange (21) of the brake member (20). The brake flange (21) is clamped between the rolled edge (12') and a peripheral undeformed radial edge (13) of the same bearing flange (11). The hardness of the material forming the axial edge (12) to be deformed by rolling is between about 200 HV and 300 HV. This edge (12) protrudes axially from the brake flange (21) by a length (d) shorter than 5 mm. The thickness (e) of said edge (12) is within 1 and 3.5 mm. The axial thickness (a) of the edge (12') deformed by rolling against the brake flange (21) is less than 3.5 mm and the axial thickness (c) of the undeformed radial peripheral edge (13) exceeds said axial thickness (c) by a length x=0.4.div.1 mm.

Abstract: There is disclosed a system for mounting a wheel hub bearing unit into a cylindrical seat (11) obtained in the suspension standard (12) of a vehicle. An axially outer circumferential groove (16) is obtained in the cylindrical seat (11). Proximate to the axially outer side (10a) of the outer race (10) of the bearing there is provided an elastic insert(15) of annular shape having a radial portion (15a) adjacent to said tace (10a) and constituting an axial stopping means for the outer race of the bearing. Elastically flexible portions (15b) are radially protruding from the outer surface or the bearing and are adapted to elastically bend and snap fit into said qroove (16) when the insert (15) is pushed axially into the cylindrical seat (11) of the suspension standard (12).
