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 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 inner rim, 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. Each of the gas springs may include a gas cylinder having an inner surface, and a piston movable within the gas cylinder. The piston may include a shaft, a piston head coupled to the shaft and having at least one recess therein, and at least one biasing member within the at least one recess. Each gas spring may also include at least one damping member adjacent the at least one biasing member and within the at least one recess to frictionally engage the inner surface of the gas cylinder.

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.

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. Gas springs may be operatively coupled between the inner rim and the outer rim and permitting relative movement therebetween. The wheel assembly may also include a sensor configured to sense the relative movement between the inner and outer rims.

The wheel assembly may also include a sensor configured to sense the relative movement between the inner and outer rims.

A mine material processing apparatus may include a rotatable drum to process mine material, and wheel assemblies configured for rotation of the rotatable drum. Each wheel assembly may include an inner rim, an outer rim surrounding the inner rim, and gas springs operatively coupled between the inner rim 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 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.
