Non-pneumatic tire
InactiveUS7201194B2Supporting massHigh effective radial stiffness in tensionNon-inflatable tyresPneumatic tyre reinforcementsElastomerShear modulus
A structurally supported tire includes a ground contacting tread portion, a reinforced annular band disposed radially inward of the tread portion, and a plurality of web spokes extending transversely across and radially inward from the reinforced annular band and anchored in a wheel or hub. The reinforced annular band comprises an elastomeric shear layer, at least a first membrane adhered to the radially inward extent of the elastomeric shear layer and at least a second membrane adhered to the radially outward extent of the elastomeric shear layer. Each of the membranes has a longitudinal tensile modulus sufficiently greater than the shear modulus of the shear layer so that when under load the ground contacting portion of the tire deforms to a flat contact region through shear strain in the shear layer while maintaining constant the length of the membranes, the web spokes transmitting load forces between the annular band and the hub through tension in the web spokes not connected to the ground contacting portion of the tire.

A compliant wheel includes a compliant band and a plurality of web spokes extending transversely across and inward from the reinforced compliant band for attachment to a hub. The compliant band bends to comply with a contact surface and to envelope obstacles. The web spokes transmit load forces between the compliant band and the hub through tension in the web spokes not connected to the ground contacting portion of the wheel. The outer surface of the compliant band may be formed to include a tread, or a separate tread band may be attached.

Tension-based non-pneumatic tire
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, curved, oriented, and comprised of varying thicknesses of material which 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.

Web elements are sized, oriented and comprised of a material that facilitates buckling when subjected to a compressive 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.

Annular ring and non-pneumatic tire
The present invention provides an annular beam of monolithic construction of one homogeneous material and a related efficient, low-cost non-pneumatic tire. Specific geometric design, combined with nonlinear elastomer physical properties, enable the suppression of all reinforcing belts, continuous fibers, or other strengthening layers in the annular beam. The annular beam consists of at least two bands that are continuous in the circumferential direction and connected by a web geometry. The non-pneumatic tire consists of the annular beam, a ground contacting portion, a central wheel, and a plurality of web spokes that connect the wheel and beam. When the tire is loaded to a design load against a flat surface over a design contact length, a contact area of essentially uniform pressure is produced, while the load is transmitted from the beam to the hub via tension in the web spokes. The tire can be economically manufactured.

InactiveUS20130340902A1Quiet and comfortable rideReduce rolling resistanceHigh resiliency wheelsMetalworkingRolling resistance
Shock-absorbers used as wheel-spokes between wheel-hub and rigid rim, which may be lined with threaded rubber or having gripping features otherwise. It reduces rolling resistance, saving fuel. It improves drivability. The compliance of the shocks is commensurate with that of a comparable inflated tire, but optimized passively or actively circumferentially, vertically and laterally. Rubber-bushing or spoke-inclination enhances driving stability. Giant field assembled mining-truck-wheels may be produced and deployed and field-assembled quickly by common metalworking shops at fractional cost and weight. It is environmentally friendly, for hardly using or not using rubber. The gas or liquid of the shock spokes may be interconnected and cooled. Soft and hard driving may be controlled manually or by computer on the fly. It is suitable for applications ranging from bicycle wheels to aircraft landing gears. It is fireproof, bulletproof, airless and silent. It cannot bounce or skid at jumpstart or braking and on ice.
