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 inner rim. 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. An inboard flange may extend radially outward from an inboard side of the inner rim to define an inboard mechanical stop with the outer rim. An outboard flange may be spaced from the inboard flange and extend radially outward from an outboard side of the inner rim to define an outboard mechanical stop with the outer rim.

A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

Wheel with an in-wheel suspension system, and suspension member thereof. Wheel includes: stationary member including an axis, rotary member rotatable about the axis, and selective suspension system. The selective suspension system has at least one suspension member positioned between the stationary member and the rotary member, thereby providing a fixed distance therebetween, and retains the fixed distance when stressed up to a threshold value, and recoverably alters the fixed distance when stressed over the threshold value. The suspension member includes: cylindrical housing, piston slidably movable in the cylindrical housing, and compression spring whose first end is connected to the piston and second end is connected to the housing. The compression spring, when fully relaxed or compressed under the threshold value, maintains the housing and piston at a normally fixed distance. Applicable to wheelchairs and bicycles, among other self-propelled and powered vehicles.

A wheel connectable to a vehicle. The wheel includes a stationary member having an axis, a rotary member rotatable about the axis, and at least one support member positioned between the stationary member and the rotary member, thereby providing a normally fixed distance therebetween. The support member is adapted to retain the distance when stressed up to a threshold value and to recoverably alter the distance when stressed over the threshold value.

A wheel assembly for a vehicle may include an inner rim to be coupled to the vehicle, and an outer rim surrounding the inner rim. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide relative movement between the inner rim and the outer rim. Each of the gas springs may include a gas cylinder body, and a gas piston including a hollow piston shaft and an enlarged piston head coupled thereto. The enlarged piston head may be slideably moveable within the gas cylinder body and define first and second gas cylinder chambers on opposing first and second sides of the enlarged piston head. The enlarged piston head may have an orifice therethrough permitting gas flow between the first gas cylinder chamber and the hollow piston shaft.
