A wheel assembly may include an inner rim, and an outer rim surrounding the inner rim. The outer rim may include outer rim segments each hingeably coupled in end-to-end relation to an adjacent outer rim segment to define the outer rim. The wheel assembly may also include gas springs operatively coupled between the inner and outer rims, and tread members each carried by a respective one of outer rim segments.

A wheel assembly for coupling to an axle may include an outer rim, distal inboard attachment points coupled to the outer rim, and distal outboard attachment points coupled to the outer rim. The wheel assembly may also include an axle attachment assembly that includes a medial portion to be coupled to the axle, rotationally spaced inboard arcuate arms extending outwardly from the medial portion and defining proximal inboard attachment points, and rotationally spaced outboard arcuate arms extending outwardly from the medial portion and defining proximal outboard attachment points. The wheel assembly may also include inboard gas springs, each coupled between respective ones of the distal inboard attachment points and the proximal inboard attachment points, and outboard gas springs, each coupled between respective ones of the distal outboard attachment points and the proximal outboard attachment points.

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 said inner rim and said outer rim. The wheel assembly may also include hydraulic dampers operatively coupled between the inner rim and the outer rim.

The present invention relates to moving apparatus based on bearing points created by ends of lever arms with changeable length. The lever arm comprises two main components: body and end of lever arm. Lever arm body moves spirally or pendulously around the axis which is different from its axis, end of lever arm moves in and out along the lever arm body. The combination of movement of body and end of the lever arm creates bearing points of the apparatus on the terrain, thus creating capability to overcome barricades of the apparatus. Moreover, the combination of these two movements, when following appropriate principles, creates equilibrium for the frame of the apparatus on various terrains.
