A hub for bicycles or the like including a hub shell which is rotatably supported relative to a hub axle, a rotor rotatably supported relative to the hub axle, and a freewheel device having two interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each contain axial engagement components. The hub-side freewheel component is non-rotatably and axially fixedly connected with the hub shell. The rotor-side freewheel component is non-rotatably connected with the rotor and is movable in the axial direction relative to the rotor and the hub shell between a freewheel position and an engagement position. Rolling members are provided for defined accommodation in the hub-side freewheel component to support the hub shell relative to the hub axle. The hub-side freewheel component is connected with the hub shell through a multiple thread having at least two separate, axially spaced apart thread grooves.

A hub is provided for two-wheeled vehicles having a hub axle, a hub body, a rotatable driving device, and having a toothed disk freewheel. The toothed disk freewheel includes a pair of engagement components cooperating with one another, each having at least one axial toothing. The axial toothings are biased to an engaging position via a biasing device. The biasing device is configured as a pulling force device which pulls both axial toothings together.

An axle depends from a heavy-duty vehicle. Each one of a pair of wheel end assemblies is mounted on a respective one of the ends of the axle. Each wheel end assembly includes a pair of bearings mounted on a spindle of the axle, and a wheel hub rotatably mounted on the bearings. A cavity is formed in the wheel end assembly between the bearings. A port is formed in the wheel hub and extends axially inwardly from an outboard end to a lubricant cavity of the hub, and angles radially inwardly from the outboard end to the lubricant cavity at an angle relative to an axial centerline of the hub. Lubricant for the bearings is introduced into the cavity by means of the port, and the port is tapped to receive a plug to seal it and contain the lubricant in the cavity. The port also provides a visual indicator if there is a leakage of semi-fluid grease.

An apparatus for a vehicle is provided that includes an axle with a keyway. A spindle sleeve is present that has a spindle sleeve inner surface axis coaxial with the axis of the axle. A spindle sleeve outer surface axis is not coaxial with the axis of the axle, and the spindle sleeve has a sleeve washer that has a keyway tab. A retaining nut is in selective rotating communication with the sleeve washer such that rotation of the retaining nut is communicated to the sleeve washer to cause the spindle sleeve to rotate relative to the axle when the retaining nut is in rotating communication with the sleeve washer. Rotation of the retaining nut is not communicated the sleeve washer to cause the spindle sleeve to rotate relative to the axle when the retaining nut is not in rotating communication with the sleeve washer.

A wheel support device for a vehicle includes a bearing that rotatably supports a wheel, and is lubricated by a lubricant, a bearing support member, and a self-discharge type charge eliminator provided on a surface of a particular member. The self-discharge type charge eliminator is configured to change air around the self-discharge type charge eliminator into negative air ions, and eliminate charge by causing the air ions to attract positive charges of the particular member for neutralization, so as to reduce the quantity of charge of the particular member, and thereby reduce the quantity of charge of the lubricant.

To obtain a structure wherein water having entered the gap between the bottom surface of an annular groove in a rotation-side flange and the inside surface in the axial direction of the brake rotor can be easily drained to the outer space. The outer diameter DO of the annular groove 15 is larger than the diameter DDI of the inscribed circle of the opening portion outside in the axial direction of the water drain holes 17a and is smaller than the diameter DDO of the circumscribed circle of the opening portion outside in the axial direction of the water drain holes 17a.

Wheels for use on vehicles and methods of manufacturing vehicle wheels are described in the present disclosure. According to one embodiment, a method includes a step of manufacturing a wheel that includes a rim, a center disk, and a plurality of spokes. The rim may include a substantially-cylindrical barrel adapted to seal a tubeless tire. The center disk may include a central bore adapted for engagement with an axle of a vehicle. Also, the plurality of spokes may be adapted to connect the center disk to the rim. The method further includes the step of deforming outwardly-facing surfaces of the spokes using one or more hammering or punching instruments.

The air transmission structure includes a statorhaving an annular outer wall with at least one aperture, an air inlet, and an air passage between the air inlet and the at least one aperture on the annular outer wallbiased against the non-rotating spindle. A housing includes interior annular walls mounted in radially spaced relation with the annular outer wall of the stator to form an annular cavity therebetween, and at least one aperture formed through the interior annular wall, and air outlet, and an air passage between the at least one aperture and air outlet. A seal is inserted within the annular cavity and defines a radial air passage between the apertures defined within the stator annular outer wall and the housing interior annular wall. An annular bearing between the stator and housing is configured to allow the housing to rotate with respect to the stator.

The invention relates to a running gear structure (4) for a commercial vehicle. The running gear structure comprises a lower transverse strut (8) and an upper transverse strut (9). The lower transverse strut (8) and said upper transverse strut (9) are fixedly connected to each other. The upper transverse strut (9) comprising two recesses (12, 13) which limit a space (14) located above the lower transverse strut (8). The space (14) is open at least in upper direction and dimensioned for accommodating a suspension spring (6). Preferably, an axle body and longitudinal swinging arms (22, 23) of the running gear structure (4) have a skeletal design with a plurality of struts (5). It is possible that the running gear structure (4) is L-shaped in a side view. Here, one leg of the L is formed by a horizontal structure part forming the longitudinal swinging arms (22, 23) whereas the other leg of the L is formed by a vertical structure part forming the axle body.

A bicycle wheel assembly may include a rim, a hub assembly, a plurality of spokes and a damper assembly. The damper assembly includes a damping element configured to apply a damping force against at least one spoke of the plurality of spokes. The damping force may be applied in an axial direction of the bicycle wheel and/or to a segment of the at least one spoke near the hub assembly.
