A non-pneumatic tire is described that includes a ground contacting annular tread portion, a shear band, wherein the shear band is formed of a first and second inextensible layer, and a low modulus material positioned between the first and second inextensible layer. The non-pneumatic tire further includes a connecting web positioned between a hub and the shear band, wherein the connecting web is formed of one or more spokes extending from an inner ring to an outer ring, wherein the one or more spokes are formed from a material reinforced with a three dimensional spacer structure.

A web structure for a non-pneumatic tire includes a first corrugated ring having a first plurality of peaks and a first plurality of valleys. The first corrugated ring is a metal ring. The web structure further includes a second corrugated ring having a second plurality of peaks and a second plurality of valleys. The second corrugated ring is a metal ring. The second plurality of valleys are affixed to the first plurality of peaks by brazing or welding.

A non-pneumatic tire (1) includes three or more tubular bodies (2) and a plurality of elastically deformable connecting members (3) interconnecting the tubular bodies (2) and disposed along a tire circumferential direction in each annular space (9) provided between the tubular bodies (2) adjacent to each other in a tire radial direction. The tubular bodies (2) are provided with an inner tube (6) positioned on an innermost side in the tire radial direction and attached to an axle, an outer tube (4) positioned on an outermost side in the tire radial direction, and an elastically deformable intermediate tube (8) positioned between the inner tube (6) and the outer tube (4). The connecting member (3) is provided with a pair of connecting plates (21 and 22) having both end portions in the tire radial direction directly connected to the tubular body (2) and extending in the tire radial direction and separated in the tire circumferential direction from an outside toward an inside in the tire radial direction. A position (P1) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the outside in the tire radial direction and a position (P2) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the inside in the tire radial direction are shifted in the tire circumferential direction in the intermediate tube (8).

A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring. The support structure is constructed of a thermoplastic material and having reinforcement cords embedded therein. The non-pneumatic tire also includes a circumferential tread extending about the outer ring.

The invention provides in a first aspect a non-pneumatic tire and wheel assembly comprising an outer annular ring having a ground contacting tread portion and a shear band, one or more spoke disks, wherein each spoke disk is connected to the shear band, wherein each spoke disk has at least two spokes, wherein each spoke has a first leg and a second leg, wherein a continuous strip of reinforcement is received in the first leg and the second leg.

A spiral spring wheel includes a ring spring and a leaf spring assembly surrounding an outer surface of the ring spring. A shoe is placed over the leaf spring assembly. The shoe sidewalls extend past the leaf spring assembly and tuck under the ring spring. Each torsion spring in a first plurality of torsion springs extends in a clockwise spiral shape from a flange to an inner surface of the ring spring. Each torsion spring in a second plurality of torsion springs extends in a counterclockwise spiral shape from the flange to the inner surface of the ring spring.

An assembly has a wheel and a nonpneumatic tire. The nonpneumatic tire includes a plurality of helical springs. Each helical spring includes a first end portion, a second end portion, and an arching middle portion. Each helical spring being is interlaced with at least one other helical spring thereby forming a laced toroidal structure extending about an entire circumference of the nonpneumatic tire. The toroidal structure supports an entire load placed on the nonpneumatic tire. The plurality of helical springs are constructed of a predetermined material that maintains strength and ductility down to 17 K.
