A wheel hub bearing for motor vehicles, comprising a hub and a bearing unit in turn comprising a radially outer ring, at least one radially inner ring, at least one crown of rolling bodies between the radially outer ring and the radially inner ring, whereas the hub has a radial stiffening. The radial stiffening of the hub has a misalignment (d) respect to a seat, i.e. a distance between a centerline axis (Y) of the seat of the radially inner ring on the hub and a centerline (Z) of the radial stiffening less than or equal to 25% of a length (l) of the seat.

Described herein is an axle assembly and method of fabrication thereof. The axle assembly includes an axle having a first geometric shape housed within an axle housing having a second geometric shape. A shock absorber is located between the axle and the axle housing. The shock absorber supports the axle within the axle housing and comprises a first material and comprises a multi-sided configuration. The first geometric shape and the second geometric shape comprising polygons.

Hub bearing assembly for a vehicle wheel, the assembly having an axial tubular appendage capable of being inserted into a central hole of a wheel of the vehicle, and wherein the tubular appendage has a radially outer surface of substantially cylindrical shape; a collar of cylindrical shape being mounted on the tubular appendage so as to cover a second centring section of the radially outer cylindrical surface, and having an insert of metallic material and an inner coating layer which at least partially covers the insert and is formed on the insert by galvanizing.

An axle tube assembly includes an axle tube, a first tube reinforcement apparatus disposed in the axle tube at one end and a second identical tube reinforcement apparatus disposed into the axle tube at the second end the reinforcement apparatuses welded in place to the axle tube, a first spindle assembly coupled to the first tube reinforcement apparatus, a second spindle assembly coupled to the second tube reinforcement apparatus, and an elongated connector rod or tube connected to the first and second to reinforcement apparatuses inside the axle tube and disposed between the reinforcement apparatuses the first and second spindle assemblies having spindle bodies welded to the cylindrical ends of the axle tube.

A wheel hub includes a one-piece hub base body configured to surround at least a portion of a rolling-element bearing, the base body having a first axial end region configured to attach to a wheel adapter and/or to a wheel and a second axial end region axially opposite the first axial end region. An annular reinforcing body, which may be a metal band, is mounted on a radially outer surface of the second axial end region and connected to the radially outer surface at a joint.

A method of manufacturing a rolling bearing unit for supporting a wheel includes detecting a current value flowing through an electric motor (19) configured to drive a roll (22) and determining a time to terminate a caulking process on the basis of the detected value when a caulking section (13) is formed by pressing the roll (22), inclined with respect to a central axis of a hub main body (7) and supported in a rotatable state about a central axis of the roll, against a cylindrical section (12), installed on an inner end portion of the hub main body (7) in the axial direction, while the roll (22) is rotated about the central axis of the hub main body (7).

An automobile hub of a multilayer rim includes a wheel disc and a rim that is composed of at least two layers of metal rings by nesting, and a gap is preset between two adjacent metal rings; an outer side of one end of the wheel disc includes axial rim mounting grooves, and one end of the rim is inserted into the rim mounting grooves to fix the rim to the wheel disc.

A manufacturing method of a wheel bearing device, the wheel bearing device including an outer ring member, an inner shaft member that includes a shaft portion that has an inside raceway and a flange portion, a plurality of rolling elements, a seal provided at an end portion of the outer ring member on the first axial side and including an axial lip, and a lip contact surface provided on the side of the inner shaft member and contacted by the axial lip, includes: processing the outside raceway with a distance in an axial direction from a first reference position being managed, a first reference position being set on the outer ring member; and providing the seal at a predetermined position, in the axial direction, of the outer ring member with respect to the first reference position.

A wheel includes a main hub portion having outer and inner portions, the inner portion being spaced from the outer portion by a main hub sidewall; a ring portion configured to engage the main hub portion so as to enclose the outer portion and the inner portion and create an enclosed void; and an exterior covering surrounding at least part of the main hub portion and the ring portion at the enclosed void. A method of forming a wheel includes forming a main hub portion having an outer portion and an inner portion; forming a ring portion configured to engage the main hub portion so as to enclose the outer portion and the inner portion and create an enclosed void; assembling the main hub portion and the ring portion into an assembled hub; and overmolding an exterior covering surrounding at least part of the main hub and ring portions.

An axle assembly for a vehicle including a differential assembly, a first axle tube extending outwardly from a first side of the differential assembly and defining an axle bore, a first axle shaft rotatably received in the first axle tube, and defining an annular groove extending radially inwardly from its outer surface, a retainer nut axially fixed to a distal end of the first axle tube, the retainer nut having an annular flange extending inwardly into the axle bore and defining an annular outer raceway, a snap ring received in the annular groove, and an axial thrust component disposed in the axle bore of the first axle tube between the snap ring and the outer raceway of the retainer nut.
