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, an outer rim surrounding the hub, and gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension permitting relative movement between the inner rim and the outer rim. The wheel assembly may also include a sidewall cover assembly that includes an inner sidewall cover coupled to the inner rim and extending radially outward toward the outer rim. The sidewall cover assembly may also include an outer sidewall cover coupled to the outer rim and extending radially inward toward the inner rim and in sliding overlapping relation with the inner sidewall cover permitting relative movement between the inner sidewall cover and the outer sidewall cover.

A system for use in providing a load on a bearing mounted to a shaft includes a preload apparatus having a first extension and a second extension engageable with an inner race of the bearing and configured to provide a compressive load to the bearing. The first extension has a first projection and the second extension has a second projection. A stop ring is configured to limit a radially inward movement of the first extension and the second extension toward each other to position the first projection and the second projection relative to the bearing.

A wheel assembly 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 permitting relative movement between the inner rim and the outer rim. The wheel assembly may also include tread assemblies carried by the outer rim. Each tread assembly may include a tread member support coupled to the outer rim, and spaced-apart tread members carried by the tread member support and defining a tread pattern therebetween. Each tread member may include at least one rubber layer, and at least one reinforcing layer in stacked relation.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A system for use in providing a load on a bearing mounted to a shaft includes a preload apparatus having a first extension and a second extension engageable with an inner race of the bearing and configured to provide a compressive load to the bearing. The first extension has a first projection and the second extension has a second projection. A stop ring is configured to limit a radially inward movement of the first extension and the second extension toward each other to position the first projection and the second projection relative to the bearing.

A wheel assembly for a tire includes a circular hub member for securing to a rotatable axle of a vehicle, a first rim piece for engaging the hub member, a second rim piece for engaging the first rim piece, and a plurality of cylindrical sleeves for engaging both the first rim piece and the second rim piece. The first rim piece has cylindrical first shafts each engaging a first end of one of the sleeves. The second rim piece has cylindrical second shafts each engaging a second opposite end of one of the sleeves. An outer cylindrical surface of each sleeve engages a separate and distinct part the tire.

A lock-ring system may include one or more lock-ring sections configured to at least partially define an annular lock-ring and one or more coupler plates configured to couple a first ring section end of a first lock-ring section to either a second ring section end of the first lock-ring section or to a ring section end of a second lock-ring section. The one or more coupler plates may be configured to be received in ring recesses of the one or more lock-ring sections. The one or more coupler plates may be coupled to the one or more ring section ends by fasteners and may be configured to slide relative to the ring recesses when the fasteners are loosened, so that a lock-ring formed by the one or more lock-ring sections may be mounted on, or removed from, a wheel assembly. A handle may be used to assist with maintaining separation of the lock-ring sections during handling and to assist with handling the lock-ring during removal and installation of the lock-ring on a wheel assembly.

A wheel cover assembly for a vehicle wheel may include a wheel rib that is attachable to a rim inner surface of a wheel rim of the vehicle wheel, a cover body having a cover body outer surface, a cover body inner surface, and a cover body outer edge having an outer diameter that is greater than an inner diameter of the wheel rib and less than an inner diameter of an open end flange of the wheel rim. A cover mounting mechanism operatively connected to the cover body has a cover locking position wherein the cover mounting mechanism engages the wheel rib to retain the wheel rib between the cover mounting mechanism and the cover body and secure the wheel cover assembly to the vehicle wheel when the wheel rib is attached to the rim inner surface.

Methods and devices and clamps for separating a hub from a rotor of a rotor/hub assembly, including a platform having a top portion to receive the rotor and an opening to allow a pusher from a jack or press to pass through the opening, and a set of clamps configured to hold the rotor in a fixed position with respect to the platform while the pusher pushes through the opening to contact the hub to separate the hub from the rotor. The clamps are generally C-shaped and devoid of moving parts and slip inwardly upon the platform to hold the rotor while the pusher pushes upward to release the hub from the rotor, and the clamps have a slot to allow the clamps to rotate and store out of position in a non-use mode.

A vehicle includes a vehicle wheel, a vehicle frame and an adjustment mechanism configured to move the vehicle wheel relative to the vehicle frame. The adjustment mechanism includes a cam stud and a cam spacer. The cam stud extends at least partially through the vehicle frame. The cam spacer is rotationally fixed to the cam stud. Rotating the cam spacer moves the vehicle wheel relative to the vehicle frame.
