A wheel (10) comprises a main body (12) and is provided with at least one reinforcing structure (14) which increases the strength of the wheel (10). The reinforcing structure (14) is at least partially integrated inside the main body (12).

A journal for coupling a wheel to an axle is configured to be mounted in a bore of the wheel. The journal defines a reception space for receiving an axle. A locking element is pivotally mounted on the journal from a release position in which the axle is removable from the reception space and secured position in which a tooth of the locking element is engaged with a groove in the axle. When the tooth of the locking element is engaged in the groove withdrawal of the axle is prevented.

A wheel has a tire, two wheel disks disposed in a center of the tire, and a gasket disposed between the two wheel disks. Each of the wheel disks has an axle hole, a plurality of threaded holes, and a plurality of lock holes. The gasket has a center hole, a plurality of threaded apertures, and a plurality of lock apertures. An axle passes through the center hole and the axle holes.

A wheel comprising a plurality of wheel plies, each wheel ply including concentric inner and outer hoops and a plurality of circumferentially spaced spoke loops therebetween, wherein each of the spoke loops is entrapped within the hoops. In one embodiment the wheel comprises a laminate of alternating wheel plies and intermediate plies bonded together. A spoked frame comprising one or more of the wheels is provided, the frame including fairing means to substantially envelope the spokes and retain...

A journal for coupling a wheel to an axle has a main tubular body portion with a reception space for the axle and a separate locking element. The locking element is mounted in a cradle for pivotal movement about a pivot axis from a release position in which the axle is removable from the reception space to a position in which the axle is secured in position is the reception space. A biasing member such as a magnet, a spring or a tube of resilient material biases the locking element into the secu...

A wheel has a rigid rim, a soft tire arranged on the rigid rim, and a unit for generating different pressures from inside in the soft tire in contact zone of tire with road surface, at opposite sides of a vertical transverse plane of symmetry of the rim so as to cause pushing of the tire with rim of wheel along a roadway, the tire being subdivided in a plurality of separate chambers spaced from one another in a circumferential direction, the unit for generating different pressures being operativ...

Wheel, in particular, for a motor vehicle with a rim and a spider, where a bolted connection is provided in the area of transition from the rim to the spider, in which a bolt head or a nut on the outside acts in conjunction with a contact surface on the spider, where the bolted connection includes a spacer sleeve which, with one of its sides, acts in conjunction with the bolt head or the nut and, with its other side, with the contact surface in such a way that the bolt head or the nut projects a...

A wheel for a vehicle comprises a rim disposed about the rotational axis of the wheel and having a pair of axially spaced, circumferentially extending bead seats interconnected by a generally cylindrical base. An annular waffle located in a plane generally perpendicular to the rotational axis is secured to the base intermediate the axial ends thereof. A disk is removably secured to the waffle by way of a plurality of fasteners. The disk and waffle carry co-operating formations which can be broug...

A wheel comprising (i) an axle secured to a movable body, (ii) a rotator journaled on the axle so as to be freely rotatable and having at least three apexes disposed rotationally symmetrically around the axle, and (iii) rollers, each roller being mounted on one of the apexes of the rotator so as to be freely rotatable. Each side between apexes of the rotator is provided with a guiding surface which has small frictional resistance and is slidable.

A wheel, in particular for a bicycle, preferably for a motorcycle, with a hub, a rim, and spokes or a disk extending between the hub and rim. The wheel is vertically divided so as to include two wheel parts, and each of the two wheel parts comprises as integral parts one half of each of the hub, the spokes or the disk, and the rim. The wheel is designed and constructed to provide a simple and cost-favorable production, while ensuring the necessary stability or rigidity. The two wheel parts are m...
