Abstract: A wheel assembly for coupling to an axle may include an outer rim, and distal inboard and outboard attachment points coupled to the outer rim. An inboard axle attachment assembly may include an inboard medial portion to be coupled to the axle and angularly spaced inboard arms extending outwardly from the inboard medial portion and defining proximal inboard attachment points. An outboard axle attachment assembly may be rotationally offset from the inboard axle attachment assembly and include an outboard medial portion to be coupled to the axle and angularly spaced outboard arms extending outwardly from the outboard medial portion and defining proximal outboard attachment points. Inboard gas springs may each be coupled between respective ones of the distal inboard attachment points and the proximal inboard attachment points, and outboard gas springs may each be coupled between respective ones of the distal outboard attachment points and the proximal outboard attachment points.

Abstract: A wheel assembly (1030) includes an inner rim (1031) to be coupled to the hub of the vehicle, and an outer rim (1033) surrounding the inner rim (1031). The wheel assembly (1030) also includes gas springs (1050) operatively coupled between the inner rim (1031) and the outer rim (1033) to provide a gas suspension permitting relative movement between the inner rim (1031) and the outer rim (1033). The wheel assembly (1030) also includes tread assemblies (1070) carried by the outer rim (1033). Each tread assembly (1070) includes a tread member support (1071) coupled to the outer rim (1033), and spaced-apart tread members (1072) carried by the tread member support (1071) and defining a tread pattern therebetween. Each tread member (1072) includes at least one rubber layer (1085), and at least one reinforcing layer (1086) in stacked relation.

Abstract: 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. An outer ring may be adjacent an inboard side of the outer rim and defining a closeable gap with adjacent interior portions of an inboard side of the inner rim to define a mechanical stop to limit relative movement between the inner rim and outer rim. The gas springs may be arranged on an outboard side of the outer ring.

Abstract: An off-highway vehicle (820) includes an off-highway vehicle frame (811) and a motor (814) carried by the off-highway vehicle frame (811). The off-highway vehicle (820) includes wheel assemblies rotatably coupled to the off-highway vehicle frame (811) without an intervening vehicle suspension and at least some of the wheel assemblies being driven by the motor (814). Each of the wheel assemblies may include an inner rim (831) coupled to a hub (821), an outer rim (833) surrounding the inner rim (831), and gas springs coupled between the inner rim (831) and the outer rim (833) to provide a gas suspension for relative movement between the inner and outer rims.

Abstract: A wheel assembly to be coupled to a hub of a vehicle, may include arcuate inner rim assemblies removably coupled together to define a circular inner rim to be coupled to the hub of the vehicle. Each arcuate inner rim assembly may include an arcuate inner rim segment, and an arcuate inner ring segment extending radially outward from the arcuate inner rim segment. The wheel assembly may also include arcuate outer rim assemblies removably coupled together to define a circular outer rim. Each arcuate outer rim assembly may include an arcuate outer rim segment, and an arcuate outer ring segment extending radially inward from the arcuate outer rim segment. The wheel assembly may also include gas springs operatively coupled between the circular inner rim and the circular outer rim to provide a gas suspension for relative movement therebetween.

Abstract: 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 with associated integral hydraulic dampers coupled between the inner and outer rims to provide a suspension for relative movement between the inner and outer rims. Each gas spring and associated integral hydraulic damper may include a first cylinder body and a second cylinder body slidable therein, and a first seal defining first and second gas chambers within the first cylinder body. Each gas spring and associated integral hydraulic damper may also include a shaft extending within the first cylinder body and into the second cylinder body defining a hydraulic fluid chamber, and an enlarged orifice body coupled to the shaft defining a hydraulic damper with the second cylinder body.
