A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.

A thermoplastic wheel hub (10) includes a center hub (26) for attachment to a wheel bearing (20) of a vehicle. The center hub (26) has a central shaft aperture (28) extending axially therethough and a plurality of lug apertures (30) spaced radially from and circumferentially about the central shaft aperture (28). The thermoplastic wheel hub (10) also includes a plurality of ribs (40) extending radially outwardly from the center hub (26). The thermoplastic wheel hub (10) further includes a cylindrical tire mount (46) connected to the ribs and extending axially in substantially a plane for mounting a non-pneumatic tire (12) thereon.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

A vehicle wheel overlay attachment system disclosed herein provides for wheel overlays, or wheel skins, that are readily installable over existing wheels by securing directly to a wheel center cap. The center cap is adapted to be inserted into the center hub portion of the wheel, much like a traditional center cap, but also contains a system for securing a wheel overlay to the center cap. When properly installed on the center cap, the wheel overlay will be snugly positioned over the wheel thereby changing the appearance of the vehicle wheel.

The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

The purpose of the present invention is to minimize decline in endurance, while improving vibration performance. The spokes of an airless tire are provided, as an integrated unit, with an outside annular portion joined to the inside peripheral surface of a tread ring, an inside annular portion joined to the outside peripheral surface of a hub, and a spoke plate portion of constant thickness providing linkage therebetween. The radial inner edge and the radial outer edge of the center plane of thickness of the spoke plate portion are respectively diagonal with respect to a tire axial-direction line. The intersection line at which the center plane of thickness intersects a plane that is at a right angle to the tire axial-direction line constitutes a straight line. The spoke length, which is the length from the radial inner edge to the radial outer edge along the intersection line, is constant for any given location in the tire axial direction.

A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.
