A hub for bicycles includes a hub shell which is rotatably supported relative to a hub axle by two roller bearings disposed on opposite ends of the hub shell, a rotor rotatably supported relative to the hub axle by two rotor bearings, and a freewheel device having an interacting hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each have axial engagement elements and are axially movable relative to one another between a freewheel position and an intermeshing engaging position. The rotor is disposed in the same axial position both in the freewheel position and in the engaging position. A driving torque is transmitted in the engaging position. The hub-side freewheel component has an inner central receiving space with a bearing seat and a roller bearing received to rotatably support the hub shell. The hub-side freewheel component includes an appendix protruding outwardly from the axial body section.

A vehicle is disclosed that may include a vertical axle, a support rod coupled to the vertical axle, and a wheel assembly coupled to the vertical axle via the support rod. The wheel assembly may include a centerless rim, a stationary hub coupled to the support rod and disposed at least partially within the centerless rim, and a roller guide supported by the stationary hub and shaped to roll along the centerless rim. The wheel assembly may be configured to rotate at least one hundred and seventy degrees relative to the vehicle.

An apparatus for a vehicle is provided that has an axle with an axis. A spindle sleeve with a spindle sleeve inner surface axis coaxial with the axis of the axle is present, along with a spindle sleeve outer surface axis that is not coaxial with the axis of the axle. The spindle sleeve has an inner surface and an outer surface. A sleeve washer is present along with a bearing that has an inner race, an outer race, and a roller. The inner race has an inner surface and a front surface in which the front surface is located forward of the inner surface in a lateral direction. The inner race has a curved surface that extends from the front surface to the inner surface, and the sleeve washer engages the front surface. The apparatus also includes a retainer that engages the spindle sleeve and the curved surface.

A bicycle hub with an axle, a shell, a rotor with a rotor body and a freewheel device with, a hub-side toothed disk device coupled to the hub shell, and a rotor-side toothed disk device interacting therewith and coupled to the rotor body, to drivingly couple the rotor to the hub shell in the driving direction and decouple from one another when freewheeling. The toothed disk devices include an end toothing and are biased to an engagement position. A sprocket accommodation is on the rotor body which includes on the hub-side end an inner radial wall to support a hub-side rotor bearing. On an end face at the hub-side end of the rotor, radially between the inner radial wall and an rotor outer wall, a circumferential accommodation accessible from the end face is configured, so the rotor-side toothed disk device is accommodated in a fixed driving manner and axially movable.

An axle assembly includes an axle housing having a passage. An axle extends through the passage. A bearing supports the axle in the passage. An adaptive bearing preload adjustment system is mounted adjacent the bearing. The adaptive bearing preload adjustment system is selectively activatable to adaptively adjust a preload force on the bearing.

A mower deck can include roller assemblies that prolong the life of bearings by more evenly distributing the roller's load to the bearings. The roller assembly can include a roller that is secured between opposing bearings via a tapered shaft of the roller and a correspondingly tapered collar that is housed within the corresponding bearing. The interface between the tapered shaft and the tapered collar causes the collar to be secured snugly within the bearing while also providing even distribution of the roller's load to the bearing.

Systems and methods for an axle shaft system of an electric vehicle are provided. A reversible axle shaft flange is optionally couplable to the axle shaft such that in a first orientation, the reversible axle shaft flange is coupled to the axle shaft and in a second reverse orientation, the reversible axle shaft flange is decoupled from the axle shaft. The reversible axle shaft flange is detachable in order to reverse an orientation and reinstall in the other orientation. The reversible axle shaft flange couples to a wheel hub via a plurality of fasteners such that torque is transferred from the axle shaft to a wheel via the reversible axle shaft flange in the first orientation. With the axle shaft in a decoupled state, rotation is not transferred from the wheel to an electric machine such that a towing operation with wheels in contact with ground is possible.

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.

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.
