Connection device () for connecting a rim () to a wheel hub () presenting a peripheral connecting outline (), which is integral with a support body () of the wheel hub (), and a complementary connecting outline (), which is obtained circumferentially along a mounting border () of the rim (), and which presents a shape which is complementary to the peripheral connecting outline () in order to render angularly integral in relation to each other the rim () of the wheel hub (); the peripheral connecting outline () and the complementary connecting outline () both presenting a radius (R) of angularly variable dimensions with continuity on a plane with is transverse to the rotation axis (A), and are both provided with at least one respective convex portion () () in relation to the rotation axis (A).

Connection device for connecting a rim to a wheel hub

Sealing device for a rolling contact bearing () provide with a first shield () and second shield () which a re made of metal material and which are respectively coupled to an outer race () and an inner race () of the rolling contact bearing () itself, and a seal () which is made of synthetic material and which is integral to the first shield () and which presents a sealing lip () which is arranged substantially in contact with the second shield (); the first shield () is defined by a cylindrical portion () which is assembled on the outer race (), and the seal () is anchored to the cylindrical portion () in order to freely extend from and overhand the cylindrical portion () itself and presents, in axial section, a tapering shape towards a cylindrical sliding surface () of the second shield ().

Sealing device for a rolling contact bearing

Sealing device () for a wheel hub group () connected to the differential () of a vehicle, and provided with a rolling bearing (), the sealing device () being mounted in such a way as to protect the bearing () from a lubricating fluid for the lubrication of the differential (), and presenting a first shield () which is integral with an outer race () of the bearing (), a second shield () which is arranged inside the first shield () and which is integral with an inner race () of the bearing () and which faces the first shield () itself, and a dynamic sealing element () which is interposed between the first and second shields (); the second shield () being defined by a support portion () made of metallic material and force fit onto the inner race () and a cylindrical encoder () which is integral with the support portion (), and the first shield () being made of metallic material lined with rubber material, and being provided with a loophole () which is suitable for being engaged by a reading sensor () for reading a signal generated by the encoder () itself.

Sealing device for a wheel hub group

A hub-bearing unit for a motor vehicle wheel comprises a bearing housed in a central axial cylindrical seat of a radially outer annular hub adapted for connection to the wheel of a vehicle. The bearing has an rotating ring the axial width of which is greater than that of the cylindrical seat. The outer ring comprises at least one tubular projection extending axially from one side of the outer ring. The tubular projection comprises an end portion projecting beyond a side surface of the hub and cold deformed in a radially outer direction towards said side surface, so as to lock the outer ring on the hub.

Bearing-hub unit for motor vehicle wheel

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.
