A vehicular wheel hub unit includes a radially outer bearing ring, a radially inner bearing ring, and a plurality of rolling elements supporting the inner bearing ring and the outer bearing ring for relative rotation. The inner bearing ring has an axially facing metal coupling surface configured to frictionally engage a connecting surface of an element, such as a bell of a constant velocity joint, adjacent to the inner bearing ring, and the coupling surface includes at least one first region having a plurality of coupling surface ablations configured to affect an amount of friction between the coupling surface and the connecting surface. Also a method including ablating at least a first region of a coupling surface of an inner bearing ring.

Axial relative movement of an auxiliary member (30) and a hub body (22z) is performed, the hub body (22z) and an inner race (21) are combined with each other in an axial direction, and a part of the hub body (22z) deformed by a blade (33) of the auxiliary member (30) is disposed inside an engagement concave portion (26) of the inner race (21).

The invention relates to a wheel end assembly for a vehicle, comprising a central wheel support member such as a spindle or a steering knuckle, and an outboard wheel end bearing arranged concentrically around the central wheel support member. The outboard wheel end bearing comprises roller elements accommodated between an inner race-forming part and an outer race-forming part surrounding the inner race-forming part. The inner race-forming part is configured to be supported by the central wheel support member. The central wheel support member comprises a first rotational lock portion. The inner race-forming part comprises a second rotational lock portion configured to engage with the first rotational lock portion to prevent the inner race-forming part from rotating relative to the central wheel support member. The invention also relates to a vehicle comprising such a wheel end assembly.

Disclosed is a wheel having a sphere at the hub of the rim which can rotate in all directions by the ball bearing it is supported by, wherein the sphere is produced from various metals, carbon fibre, etc. material. The wheel helps to prevent vehicles from skidding off tracks at turns even at high speeds or to prevent accidents that may occur as a result of swiping of vehicles with each other particularly during competitive racing.

In one aspect of the present disclosure, a wheel hub assembly is provided that includes a hub body having an outboard end portion and an inboard end portion, a bearing assembly, and a seal. The seal includes a seal case and a sleeve. The hub body and seal case are rotatable relative to the sleeve. The wheel hub assembly further includes a stop of the bearing assembly configured to resist movement of the sleeve toward the outboard end portion of the hub body as the hub body, bearing assembly, and sleeve are advanced together in an inboard direction along a vehicle spindle. The stop permits the bearing assembly to transfer a force applied in an inboard axial direction against the bearing assembly, such as by tightening of a spindle nut, to the sleeve and urge the sleeve along a vehicle spindle.

A locking system including a lock washer, a nut, and a retainer which together act to secure a wheel hub to a spindle. The lock washer has a tab which extends through the nut and the retainer, and which wraps around and back over the retainer in order to axially and rotationally secure the retainer. The tab has an initial position that corresponds to an unlocked position and a distal end of the tab extends beyond the hub in the initial position far enough to prevent an end cap from being placed over the tab when the tab is in the initial position. As such, installation of the end cap is not possible until the tab is bent into a locked condition.

A system for use in providing a load on a bearing mounted to a shaft includes a preload apparatus having a first extension and a second extension engageable with an inner race of the bearing and configured to provide a compressive load to the bearing. The first extension has a first projection and the second extension has a second projection. A stop ring is configured to limit a radially inward movement of the first extension and the second extension toward each other to position the first projection and the second projection relative to the bearing.

In some examples, an aircraft wheel assembly includes an axle, a bearing assembly, and a hub defining a bearing bore. The bearing bore may be configured such that the dynamic radial and axial thrust bearing reactions between the axle and the hub results in a first reaction force F.sub.R applied to the hub, the first reaction force F.sub.R having a radial component, and a second reaction force F.sub.N applied to the hub, the second reaction force F.sub.N having both a radial and an axial component.

A bearing device for wheels is configured so as to reduce an amount of deformation of an opening of an outer member while minimizing an increase in overall weight, thus preventing a deterioration in rolling fatigue life. The bearing device for wheels is provided with an outer member having double-row outer rolling surfaces, a hub ring having a wheel mounting flange and having a small-diameter stepped section, and an inner member constituted by at least one inner ring press-fitted over the small-diameter stepped section, the inner member having double-row inner rolling surfaces facing the double-row outer rolling surfaces. A band-shaped section having a predetermined band width and protruding radially by a protrusion amount is formed on at least a part of the wheel mounting flange-side outer peripheral portion of the opening of the outer member.

A flanged inner ring for wheel hub bearings, the inner ring comprising a tubular body supporting the bearing, the body being coaxial with an axis (A), and a flange, which is transversal to the axis (A), the flange being provided with a plurality of threaded through holes that are distributed around the axis (A) and includes:an outer annular mounting surface and an inner surface that is axially faced towards an outer ring of the bearing; the flange having a respective base axial thickness (SAF) and comprising for each threaded through hole, a respective radial arm which is arranged on the inner surface of the flange facing the outer ring; the inner ring being forged in one piece together with the flange and the radial arms. Between each pair of adjacent arms there is a flower-shaped sector with a chamfer made by forging along the outer surface thereof.
