NON-PNEUMATIC TIRE
A non-pneumatic tire defining axial, radial, and circumferential directions. The tire includes an annular lattice structure extending radially between an inner circumferential edge and an outer circumferential edge. The lattice structure exhibits topological polarization, with the inner circumferential edge being stiffer than the outer circumferential edge. The topological polarization includes asymmetry in mechanical response to opposing forces applied to the inner and outer circumferential edges. The lattice structure which provides topological polarization endows the tire with localized softness along the outer radius, which enables extreme absorption of asperities, without transferring significant forces to the axle. In some embodiments, the lattice structure further exhibits topological protection, including the topological polarization characteristics being maintained upon experiencing wear at the outer circumferential edge. In some embodiments, the lattice structure is, or is akin to, a Kagome lattice arrangement.
Tire having replaceable discrete traction elements
A tire may comprise a hub and a plurality of discrete traction elements coupled to the hub. Each of the traction elements may comprise a backing plate and an elastomeric material bonded to the backing plate. Circumferentially adjacent traction elements may axially overlap.
Non-pneumatic tire
A non-pneumatic tire comprises: a band part including an inner band and an outer band, the outer band being separated from the inner band by a predetermined distance to surround the inner band; and a spoke part provided to extend in a circumferential direction of the tire between the inner band and the outer band, the spoke part including one or more holes when viewed in the circumferential direction and one or more holes when viewed in an axial direction of the tire.
Solid tire provided with cushioning holes
Described herein is a resilient tyre (1) designed to be used on industrial and construction machinery, said resilient tyre (1) comprising a plurality of circular layers of elastic material set on top of one another in the radial direction, said layers forming, proceeding from the centre of the resilient tyre (1) towards the periphery, an inner portion referred to as base (2), an outer portion referred to as tread (3), and two lateral surfaces (4, 4′) with height (Q). The resilient tyre (1) comprises a plurality of cushioning holes (7) made in both of the lateral surfaces (4, 4′) of the resilient tyre (1), said cushioning holes (7) substantially having a wing-like shape.

Tires with segmented tire bodies, embedded mounting elements and partially embedded cleats
Segmented tires employ segments featuring cooperating recesses and protrusions at opposing sides thereof for mating of the segments with one another in the assembled tire body. Cleated tires with embedded cleats of greater rigidity than the tire body material provide improved traction in muddy or other slippery conditions while the compressible tire body smooths out the ride harshness of the tire. Mounting elements are also embedded within the segments of the tire body for secure mounting and reliable retention of the segments.
Variable compliance wheel
A system for adjusting the compliance of a wheel is provided. In one embodiment, wheel segments are adjusted, causing the stiffness of the wheel to change. Such adjustments can be made while the wheel is rotating, allowing the wheel compliance to be changed while a vehicle is in motion.
Shear band and non-pneumatic tire
A shear band and a non-pneumatic tire is described which includes a ground contacting annular tread portion; a shear band, and a connecting web positioned between a hub and the shear band. The shear band is preferably comprised of a three-dimensional spacer fabric having a first and second layer connected by connecting members. The three-dimensional spacer fabric has a defined depth. The three-dimensional spacer structure further includes a plurality of cells formed between the connecting members, and wherein one or more of the cells are filled with a filler material. The filler material may be foam or a thermoplastic elastomer.
Shear band with interlaced reinforcements
A shear band that may be used e.g., in a non-pneumatic tire having interlaced reinforcing elements positioned within a shear layer of elastomeric material. A variety of configurations may be used to create the interlaced positioning of the reinforcing elements including e.g., a horizontal diamond or vertical diamond configuration.
Tire with variable shear element
A tire includes a central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.
