More particularly, a method of improving the performance characteristics (such as e.g., increasing the bending stiffness) of a shear band without increasing its thickness or to reducing the thickness of a shear band while maintaining its performance characteristics and to shear bands constructed according to such method is provided as well as shear bands constructed according to such method.

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.

The tire is mounted on the rim portion of the wheel and includes a cylindrical tire body presenting a transversely flat inner surface that engages the outer surface of the wheel. A plurality of traction lugs are spaced circumferentially around the tire and extend radially outwardly from the tire body. A plurality of drive lugs are spaced circumferentially around the tire, extend radially inwardly from the tire body and engage corresponding receptacles on the rim portion of the wheel.

Abstract: Tire blocks are described. The techniques described herein may enable multiple blocks of foam to substantially fill an inside of a tire. Each of the blocks used to fill a tire may have a wedge shape and a rigidity that is sufficient to operate the tire without air pressure. The wedge shape of each of the tire blocks has sides that may be positioned at least partially against sidewalls of the tire and sides that may be be positioned against other blocks of foam. The tire can then be inflated to the desired air pressure for operation. Because of the density of the foam and the wedge shape design, a failed tire can still be used for normal operation.

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, 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.

The tire body element includes multiple concentric layers with alternating spokes. A bonded multilayer cover may be employed which is received within a recess in an outer surface of the tire body element from the tire tread. An attachment plate is engaged to the cover and attached to the wheel.

Abstract: The invention provides a non-pneumatic tire which can improve a riding quality, a noise performance and the like while improving a durability, and can further sufficiently suppress a buckling of a ground portion between spokes, because a circumferential fluctuation of a tire rigidity is hard to be generated due to a positional relationship between a spoke position and a center position of the ground surface, and a strain can be dispersed into each of portions of a support structure body.

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.

Abstract: A resilient tire that supports a load without internal air pressure includes a ground contacting tread portion and sidewall portions extending radially inward from said tread portion and anchored in bead portions adapted to remain secure to a wheel during rolling of the tire. A bias ply carcass extends between the beads to support the sidewalls. A reinforced annular band is disposed radially inward of the tread portion. The band comprises an elastomeric shear layer at a radially outer side of the bias ply carcass and a membrane adhered to a radially outward side of the elastomeric shear layer. Each of the bias ply and membrane 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 foamed rubber may be one of cellular rubber or closed cell cellular rubber. The tire having further regions made of closed cell cellular rubber may be made as an integral solid rubber tire in a mold, such as a split mold in a one-step process.

Abstract: A wheel and solid rubber tire comprising a circular mounting disk having an axis perpendicular through the center of the circular disk. A wheel rim is rigidly affixed circumferentially around the mounting disk and has a cylindrical surface extending from one end of the rim to another and, axially aligned about the axis of the mounting disk. Multiple angled cross ribs having top and bottom edges rigidly affixed at the bottom edges to the cylindrical surface of the wheel rim substantially continuously thereacross at an angle from one end of the rim to the other and evenly spaced circumferentially therearound. One or more base layers of even thickness rubber are bonded to the cylindrical surface interposed between the angled cross ribs, and multiple additional layers of even thickness rubber are bonded to the one or more base layers with each additional layer bonded to the next so that a solid rubber tire is formed which is directly bonded to the wheel rim.

Abstract: The running characteristics of a tire for a wheel are improved to provide a more quiet run, by attaching to an inner and/or outer surface of the tire vibration absorbing elements. Vibration absorbing elements may even be inserted into the tire material itself. The vibration absorbing elements are secured to the tire surface in a force and moment or torque transmitting manner by vulcanization or by a suitable adhesive. A strap may hold the individual absorbing elements together or the elements may form integral parts of the strap which is secured to the tire surface, for example, by a rubber vulcanizing operation. The vibration absorber elements may be secured to an inner tube instead of to the tire.
