In a non-pneumatic tire, a plurality of first to third curved sections (21d) to (21f) and (22d) to (22f) curved in a tire circumferential direction are formed at first and second elastic connecting plates (21) and (22) in an extension direction in which the first and second elastic connecting plates extend, in a tire side view when a non-pneumatic tire (1) is seen from a tire width direction (H), curved directions of the first to third curved sections neighboring in the extension direction are opposite to each other, and each of the first and second elastic connecting plates, and inflection sections (21g), (21h), (22g) and (22h) disposed between the first to third curved sections neighboring in the extension direction has a smaller cross-sectional area than other portions.

Provided is an omni wheel including a suspension structure, which may sustain an increased load and drive on a rough terrain such as a stairway or a bumpy ground, and which includes a flywheel unit receiving power from outside and rotating around a rotation axis; suspension units formed radially on opposite surfaces of the flywheel unit; and a ground wheel having opposite ends connected to ends of a pair of the suspension units formed on one surface and the other surface of the flywheel unit, respectively.

A wheel assembly 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 and permitting relative movement therebetween. The wheel assembly may also include a rigid inboard cover ring coupled to an inboard side of the outer rim and extending radially inward toward the inner rim. A flexible inboard seal may be coupled between the rigid inboard cover ring and the inner rim.

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 the inner rim and the outer rim. The wheel assembly may also include a disk coupled to the inner rim. The wheel assembly may also include inboard lateral stops carried by an inboard interior surface of the outer rim, and outboard lateral stops carried by an outboard interior surface of the outer rim so that the inboard lateral stops and the outboard lateral stops cooperate to limit relative lateral movement of the disk and the outer rim.

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. At least one gas spring may have a controllable operating response.
