A variable track wheel comprises a rim suitable for receiving a tire, and a disc through which said wheel is mountable on a hub, said disc being removably secured by fastenings to a connecting member provided in said rim, said connecting member projecting towards a rotation axis of said wheel, said wheel further comprising a plurality of spacers interposed between an annular perimeter zone of said disc and said connecting member of said rim, said disc and said rim being mountable in a plurality of reciprocal axial positions and in a plurality of reciprocal orientations to obtain a variation in the track of said wheel, said wheel further comprising at least one centering device for mutual positioning of said disc and of said rim said centering device comprising a hole and a pin said hole or said pin being provided in said connecting member or in said disc said centering device further comprising a coupling element so conformed as to cooperate with said hole and with said pin for reciprocally coupling said pin and said hole.

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.

A composite wheel assembly and method of construction thereof is provided. The composite wheel assembly includes a wheel having an inwardly facing surface, an outwardly facing surface, a generally cylindrical barrel portion, and a plurality of apertures formed about a central hub aperture. At least one wheel cladding is fixedly bonded to at least one of the inwardly facing surface, the outwardly facing surface, and the generally cylindrical barrel portion. The wheel cladding increases the stiffness and/or strength of the wheel between about 2-16% or greater as compared to the wheel not having the at least one cladding.

A materials handling equipment has blades of a lifting fork wherein each of the blades engages a blade wheel that moves between a retracted position when the blade is lowered and an extended position when the blade is raised to lift and support a load. The blade wheels have a plurality of tires linearly aligned on a common axis, the tires each having a circular circumference and a sinusoidally varying peripheral surface. The sinusoidally varying peripheral surfaces have relative peaks and valleys uniformly spaced around the circular circumference wherein the peaks and valleys are mutually nested.

The invention at hand refers to a wheel disc brake assembly comprising a wheel rim, a coupler ring and an annular brake disc arranged in a concentric manner, wherein an outer surface of the coupler ring is connected to an inner surface of the wheel rim and an inner surface of the coupler ring is connected to an outer surface of the annular brake disc. The wheel disc brake assembly further comprises a caliper with at least two brake pads facing each other, wherein the caliper surrounds at least a part of the inner surface of the annular brake disc and the at least two brake pads are configured to press against opposite side faces of the annular brake disc.

A solid wheel for a rail vehicle includes a wheel rim arranged on the circumference of the solid wheel, a tread and a hub for a wheelset shaft, wherein the wheel rim is connected to the hub via an end wall and a rear wall, where the hub is arranged at the center of the solid wheel and includes a longitudinal axis such that a high radial and axial strength of the wheel flange as the basis for a low sound emission is provided by virtue of the solid wheel forming a cavity that is delimited by the end wall and the rear wall, where the end wall and the rear wall transition into each other below the wheel flange in an arched manner, and the end wall has first openings and the rear wall has second openings in order to open the cavity outwards in a spoked manner.

A non-inflatable tire for an agricultural implement, including a sole, a tread, and a pair of sidewalls connecting the sole to the tread is provided. A first sidewall extends from the sole to the tread, while the second includes an internal portion which extends from the sole to the tread and an external portion projecting from the tread. The first sidewall and the tread are designed so as to jointly hold the external portion of the second sidewall in line with the internal portion.

The bicycle hub assembly includes a hub axle, a hub body, a bearing unit, a lock member, and a tool engagement member. The bearing unit is configured to rotatably support the hub body around the hub axle with respect to the rotational center axis. The bearing unit includes an outer race, an inner race and a plurality of rolling members. The lock member prevents the inner race of the bearing unit from rotating relative to the hub axle. The tool engagement member is configured to rotate the inner race of the bearing unit relative to the hub axle.

The invention relates to a manufacturing method and a structure of a wheel rim. The manufacturing method mainly comprises the steps of forming a rim body made of a carbon fiber material in a cavity of a molding die; forming a rim assembly by extruding a metal material and assembling the rim assembly to the rim body; and forming a rim coating by tightly encapsulating a carbon fiber material on a surface of the rim body assembled with the rim assembly.

A wheel assembly to be coupled to a hub of a vehicle may include an inner rim to be coupled to the hub of the vehicle and an outer rim surrounding the hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between said inner rim and said outer rim. The wheel assembly may also include hydraulic dampers operatively coupled between the inner rim and the outer rim.
