The sleeve covers a radial slot formed in the projections and the arms of a spring locking ring for axially removably securing the joint bell to a toothed driving ring fixed on a rotatable hub. The other end of the sleeve has a radially inwardly projecting flange which is sealingly axially clamped against a rigid annular part secured to or integral with the hub.

Abstract: A constant velocity joint has an outer bell telescopically coupled for rotation with a rotatable hub of a hub bearing unit so as to provide torque transmission thereto. The joint bell is releasably axially coupled to a rotatable member of the hub bearing unit by an annular connector. The connector includes a radially inwardly extending annular flange axially clamped against a rigid annular part fixed to or integral with the hub, and a radially outer portion extending axially around a cylindrical surface of the joint bell. This outer portion has a resiliently radially expansible section with one or more radially inwardly extending protrusions providing a snap connection with a relief or recess formed on the cylindrical outer surface of the joint.

Abstract: A bearing unit comprises a radially outer stationary race (1) and a pair of radially inner rotatable half-races (2a, 2b). An intermediate annular chamber (8) is defined between the outer race (1) and the inner half-races. The intermediate chamber communicates with the outside through first air passages (5) formed in the outer race and with the inside of the bearing unit through second radial air passages (6) defined between the inner half-races. The second passages (6) are defined by an intermediate annular member (10) which is axially interposed between the inner half-races (2a, 2b) and forms one or more blade surfaces (12a, 12b) extending from the second passage (6) to the intermediate chamber (8) for capturing air from the intermediate chamber and conveying it into the second passage.

Abstract: The unit has a rotating hub (10) having an outwardly projecting radial flange (11) defining an outwardly facing edge (12), and a braking rotor (20) which is integral with or fixed for rotation with a flange (21, 41) which projects radially inwards and which defines an opening (23, 43) with an internal edge (22, 42). The edges (12 and 22, 42) of the two flanges (11 and 21, 41) are adjacent to each other and face each other radially. The two edges (12 and 22, 42) have, at least along one portion thereof, the same noncircular shape, for example an oval or lobe shape, in the same radial plane in order to enable the braking torque to be transmitted from the braking rotor (20) to the hub (10). The braking rotor may be mounted on the hub flange (11) by way of an annular support member (40).

Abstract: A wheel assembly includes a hub and bearing unit in which an annular hub has an axial cylindrical seat with an outer ring of a bearing fitted thereto with radial interference. The ring is locked axially on the hub between a pair of annular rims which project radially outwardly from the outer cylindrical surface of the ring and have been cold-deformed so as to engage two opposite surfaces of the hub. The hub also has an outer radial flange for fixing a brake rotor which in turn has an inner radial flange arranged substantially in the same plane as the flange. The brake rotor is locked axially on the hub by at least one cold-deformed annular rim which projects radially outwardly from the flange on the hub so as to engage a respective one of two radial surfaces of the flange.
