    Abstract: A non-pneumatic tire for supporting a load by working in tension comprising a generally annular inner ring, a generally annular outer ring, and an interconnected web having a plurality of web elements and comprising a plurality of generally polygonal openings. Web elements are sized, oriented and comprised of a material that facilitates buckling when subjected to a compressive load. By buckling, those elements in a deformed portion of the tire between a wheel and a footprint region where the tire contacts a surface can assume a significantly reduced portion of the load, if any. This causes web elements in other portions of the interconnected web to operate in tension to support the load.

    Abstract: An agricultural implement is provided that includes a hitch assembly configured to couple the agricultural implement to a tow vehicle, and a carrier frame pivotally coupled to the hitch assembly. The agricultural implement also includes a pair of wheel assemblies each rotatably coupled to the carrier frame by a respective pivot joint. The agricultural implement further includes an actuator assembly configured to rotate each wheel assembly about the respective pivot joint in a first direction by applying a first torque, and to rotate each wheel assembly about the respective pivot joint in a second direction, opposite the first direction, by applying a second torque. A magnitude of the first torque and a magnitude of the second torque are substantially equal.

    Abstract: An agricultural implement is provided that includes a hitch assembly configured to couple the agricultural implement to a tow vehicle. The agricultural implement also includes a carrier frame pivotally coupled to the hitch assembly by a main pivot joint such that the main pivot joint resists substantially all lateral loads between the carrier frame and the hitch assembly. The agricultural implement further includes a pair of wheel assemblies each rotatably coupled to the carrier frame by a respective knuckle pivot joint, and an actuator assembly configured to rotate each wheel assembly about the respective knuckle pivot joint while the agricultural implement is in both a working and transport position.

    Abstract: A run-flat device, which is inserted into pneumatic tires to allow mobility in the event of pressure loss in the pneumatic tire, can comprise an inner ring, outer ring, and an interconnected web connecting the two. The run-flat device can support an applied load by working in tension and compression.

    Abstract: A non-pneumatic tire for supporting a load by working in tension comprising a generally annular inner surface, a generally annular outer ring, and an interconnected web having a plurality of web elements and comprising a plurality of generally polygonal openings. Web elements are sized, oriented and comprised of a material that facilitates buckling when subjected to a compressive load. By buckling, those elements in a deformed portion of the tire between a hub and a footprint region where the tire contacts a surface may assume a significantly reduced portion of the load, if any. This causes web elements in other portions of the interconnected web to operate in tension to support the load. Since the tire is non-pneumatic, it may be easier to maintain and may have a longer life than standard pneumatic tires since it eliminates the possibility of blowouts, flat tires, or tires operating with low air pressure. By virtue of the portion of the tire in the footprint region not bearing a significant portion of the load, non-pneumatic tire may also exhibit a more comfortable ride subject to less noise and vibration and improved handling capabilities.
