Abstract: A wheel for a vehicle (e.g., a construction vehicle, an all-terrain vehicle, or other off-road vehicle) or other device, in which the wheel comprises a non-pneumatic tire and may be designed to enhance its use and performance and/or use and performance of the vehicle or other device, including, for example, to be able to be used longer and/or in more challenging conditions, such as, for instance, by being more thermally efficient (e.g., to avoid or reduce adverse effects such as rapid degradation in material properties that could otherwise arise due to excessive temperatures) and/or more resistant to cracking or other damage which could lead to premature failure (e.g., due to manufacturing artifacts and/or rocks and other hazards that can cut, chip, or tear it during use).
Abstract: A non-pneumatic wheel having an annular reinforcement structure that includes rectangular reinforcements within a shear layer. The rectangular reinforcements replace deforming rubber or polymeric materials and can thereby reduce the volume of deforming materials to optimize energy loss therein and reduce rolling resistance of the non-pneumatic wheel.

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. With the portion of the tire in the footprint region not bearing a significant portion of the load, non-pneumatic tire may exhibit a more comfortable ride subject to less noise and vibration and improved handling capabilities.

Abstract: The invention relates to a vehicle wheel, comprising a rigid rim and a flexible tire without an air charge, between which resilient spokes, offset at an angle with respect to the radial direction, are situated. The spokes are divided into three or more groups, which are separated axially from one another with an alternating oppositely directed angular offset.
Abstract: The present invention relates to a puncture-resistant device for a non-pneumatic mounted assembly of a two-wheeled vehicle, in particular for a bicycle, and to such a mounted assembly incorporating this device.

Abstract: The present invention provides an improved shear band for use in non-pneumatic tires, pneumatic tires, and other technologies. The improved shear band is uniquely constructed of honeycomb shaped units that can replace the elastomeric continuum materials such as natural or synthetic rubber or polyurethane that are typically used. In particular, honeycomb structures made of high modulus materials such as metals or polycarbonates are used that provide the desired shear strains and shear modulus when subjected to stress. When used in tire construction, improvements in rolling resistance can be obtained because of less mass being deformed and reduced hysteresis provided by these materials. The resulting mass of the shear band is greatly reduced if using low density materials. Higher density materials can be used (such as metals) without increasing mass while utilizing their characteristic low energy loss.

Abstract: A pneumatic tire with an internal toroidal safety structure that expands and provides emergency support between the tire tread and the wheel rim if the tire loses inflation pressure. The safety structure has an outer circumferential belt comprising one or more superposed layers of cord reinforced strips, the belt being secured to the safety structure in a relatively narrow central circumferential zone so that radial expansion of the toroidal safety structure is readily accommodated should the tire lose inflation pressure. The belt bears between the inner surface of the tread portion of the tire and the safety structure in the event of tire deflation or underinflation and thus guards against puncture. The safety structure may be an internal inflatable tube or a flexible resilient foam member, for example.
