A unit forming a wheel-hub includes an outer bearing ring that is stationary and a flanged body that is directly connected to a pillar of a vehicle are provided with respective locking surfaces for locking the outer ring inside an assembly seat of the flanged body.

Wheel-hub bearing unit

A hub-bearing assembly for rotatably mounting a tilling disc about an axis of rotation. The hub-bearing assembly includes an annular hub providing an axially extending tubular portion, comprising a housing and a radially outer flange for mounting a disc. A bearing unit is mounted within the housing. An elastic damping body axially is fitted between the radially outer flange and the disc.

Damping flange for agri-hub

A hub-bearing assembly for agricultural use having a rolling bearing, a housing, a closing cap and an axial retention feature. The roller bearing includes an outer ring, at least one inner ring, at least a row of rolling bodies and a sealing device. The housing includes an almost annular cylindrical shape, the housing at one end forming a radial flange, containing the rolling bearing and being in direct contact with the bearing outer ring. The closing cap is assembled on the housing at the opposite end with respect to the end, where the housing forms the flange. It is noted that the cap is cup shaped. The axial retention feature is located along an external surface of the outer ring. The retention feature is located opposed to the axial sliding of the outer ring with respect to the housing.

Hub-bearing assembly

A hub-bearing assembly is disclosed, wherein the hub-bearing assembly is used for rotatably mounting a tilling disc about an axis of rotation is disclosed. The hub-bearing assembly comprises an annular hub comprising an axially extending tubular portion defining a cylindrical housing and an outer flange for mounting a disc, a bearing unit mounted in the housing, and an elastic damping body arranged in the housing and radially interposed between the hub and an outer ring of the bearing unit.

Hub-bearing assembly for rotatably mounting a tilling disc

A rolling contact bearing () providing a radially inner ring () into which a shaft of a pinion unit can engage, a radially outer ring () which can be inserted into a cylindrical seat () provided in a frame (), a plurality of rolling bodies () arranged between the two rings () so as to allow the radially inner ring () to rotate with respect to the radially outer ring (), and an axial locking element () which is mounted on a lateral annular recess obtained in the radially outer ring () and can be screwed to the frame () so as to axially lock the radially outer ring () within the cylindrical seat (); an axial retaining element (), is associated with the radially outer ring () and radially interferes with the locking element () so as to secure the locking element () within the annular recess ().

Rolling contact bearing

In a hub-bearing assembly for the wheel of a motor vehicle, the hub () forms integrally or is fixedly secured to a radial flange () fixable to a wheel (). Associated with the assembly is a measuring device () mounted to a non-rotating part () of the vehicle and operatively facing a radial surface () integral with the flange (). The measuring device () detects in real time variations of the axial position of the surface () caused by elastic deformation of the flange () provoked by forces transmitted from the wheel () to the hub flange ().

Monitoring the axial load acting on the hub of a motor vehicle wheel

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

Sealing device for a flanged bearing for a wheel hub in which the flanged ends ( ) of the outer race ( ) have the metallic rings ( ) of a sealing device ( ) pressed on to their internal surfaces; each metallic ring ( ) incorporates a rubber element ( ) which is suitable for forming a static seal on the outer race of the bearing; the rubber element ( ) extends towards the inner race ( ) of the bearing ( ) to then bend back towards the outside of the bearing itself with an appendix ( ), which forms two seals ( and ) on the internal surface of a second metallic ring ( ); the latter is pressed on to the external surface of the inner race ( ) of the bearing; a rubber element ( ) is applied to the ring ( ) in correspondence with its free end ( ) which is axially turned towards the inside of the device; the rubber element ( ) presents at least two lips ( and ), one of which creates a dynamic seal between the two races ( and ) of the bearing together with the above-mentioned lips ( and ) of the metallic ring ( ), while the second lip ( ) creates a static seal of the ring ( ) against the surface ( ) of the inner race ( ) of the bearing which it faces.

Sealing device for a flanged bearing

A stud comprises a head and a stem with a threaded end length and a length having an axial knurling proximate to the head and adapted to be driven with radial interference into an axial bore of a radial flange portion fast for rotation with the hub of a motor vehicle wheel. The stud comprises at least one knurled surface having an area other than zero in a projection on a plane perpendicular to the longitudinal axis of the stud. The knurled surface is adapted to co-operate with the radial flange portion for preventing rotation of the stud.

Studs for connecting a wheel and a brake element to a motor vehicle wheel hub unit

A sealing assembly for rolling bearing comprises a shield interference fitted to a first race of the bearing. The shield comprises a rigid support having an axial sleeve portion for connection to the first race, and a radial flange portion extending towards the second race of bearing. The support forms a U-fold acting as an axial stopping means for co-operating with a mating surface of the first race to axially lock the shield with respect to said first race.
