Definitions
- the present invention relates to a tire having a reinforcing structure contained in the crown.
- the hinge effect can also provide for an unfavorable shape for the contact patch.
- the hinge effect can lead to a shorter contact occurring in the center of the tread and a longer contact occurring on the shoulders. Such activity has a deleterious effect on tread wear and rolling resistance.
- the hinge effect can also increase sensitivity of the tire to load variations.
- the shoulder ribs may experience a shorter contact with the ground man the center ribs for smaller loads.
- the shoulder ribs may be in much longer contact with the ground than the center ribs.
- This variation in the shape of the contact patch can also provide for excessive tread wear and increased rolling resistance.
- One approach for addressing the hinge effect is to provide several support belts in the crown portion of the tire.
- additional metal belts with metal cables at various angles can be provided to stiffen the tire and, therefore, reduce the hinge effect
- the addition of such belts also adds weight, which negatively affects the tire's fuel economy.
- additional heat generation can occur that also increases rolling resistance.
- a tire that can have unproved rolling resistance, tread wear, and load capacity would be useful. More particularly, a tire that can minimize or avoid the hinge effect without significantly increasing the mass or rolling resistance of the tire would be very beneficial. Such a tire that can also realize increased load capacities and improvement in durability would also be particularly useful.

- a pair of sidewall portions extend radially between a respective axial edge of the crown portion and a respective bead portion.
- a carcass ply extends between the bead portions, through the sidewall portions, and through the crown portion. The carcass ply is disposed radially- inward of the reinforcement band in the crown portion.
- the reinforcement structure can comprise a layer of at least one filament wound about the axis of rotation of the tire.
- the filament of the reinforcement structure can include a fiber selected from the group comprising polyvinyl alcohol fibers, aromatic poryamide (or "aramid”) fibers, polyamidVhnide fibers, polyimide fibers, polyester fibers, aromatic polyester fibers, polyethylene fibers, polypropylene fibers, cellulose fibers, rayon fibers, viscose fibers, polyphenylene benzobisoxazole (or ' ⁇ ") fibers, polyethylene naphthenate (TEN**) fibers, glass fibers, carbon fibers, silica fibers, ceramic fibers, and mixtures of such fibers.

Bead portions 150 each comprise a bead core 105 and a
- Carcass 110 help protect a carcass 110 that extends between the bead portions 150.
- Carcass 110 also wraps around bead cores 105 and bead apex 120 along each side of tire 100. It should be understood, however, that the present invention is not limited to tire constructions where carcass 110 is wrapped about bead cores 105 and/or bead apex 120 and includes, instead, other constructions where e.g., the carcass ends, or is anchored in, the bead portion as well.
- Carcass 110 may be constructed from a variety of materials including, by way of example, steel and various textile materials such as polyester, nylon, or rayon.
- tire 100 includes an inner liner 115 that covers the inner surface of tire 100.
- Inner liner 115 may be constructed from any material suitable for retaining the tire's inflation pressure.
- inner liner 115 may be constructed from a halo-butyl rubber.
- An inner layer 125 of rubber is positioned between inner liner 115 and carcass 110. Inner layer 125 provides additional support along radial direction R for tire 100.

- additional belts may be desired for protecting the carcass 110 and inner liner 115.
- tire 100 includes a reinforcing structure 160 located in crown portion 135 at a position that is radially inward of the tread 140.
- Reinforcing structure 160 has a circumferential extension modulus of about 5 OPa or greater and an axial plane shear modulus of about 10 MPa or greater. Accordingly, reinforcing structure 160 provides a stiffness to tire 100 that resists the hinge effect previously described.
- reinforcing structure 160 is constructed from a layer 165 mat includes a least one filament 170 wound in a coil-like manner about the axis of rotation of tire 100 and embedded in a resin 175.
- the angle a (FIG. 2) for the majority of such filaments 170 relative to the circumferential plan CP is about zero degrees.
- an angle a of plus or minus 45 degrees for filaments 170 may also be used such that the filaments are wound in a crossing manner along the circumferential direction of layer 165.
- the thickness of layer 165 (i.e. along the radial direction) may be e.g., at least about 1 to 5 mm, although other thicknesses may be used.
- the width of layer 165 (i.e. along the axial direction) is substantially the same width as the crown portion 135.
- any suitable materials meeting the mechanical properties described above may be used for the manufacture of filament 170 and resin 175.
- fibers and matrix material can be obtained commercially in a variety of forms. Fibers are available individually or as roving which is a continuous, bundled but not twisted group of fibers. Fibers are often saturated with resinous material such as polyester resin which is subsequently used as a matrix material. This process is referred to a preimpregnation. These combinations can take the form of tapes, cloth, or mats. These materials are then layed up in the desired dimensions of the reinforcement structure and then cured whereby the resin is polymerized using a number of means including heat, or UV radiation. This curing creates a permanent bond between the fibers and the resin. Ref. Jones, "Mechanics of Composite Materials", 1975. By way of example, a method and device for manufacture of a composite ring as may be used for reinforcing structure 160 is described in
- pre- impregnated composite fiber technology may also be used to manufacture reinforcing structure 160 by wrapping such fiber around a desired shape and curing same in an autoclave.
- the fibers may be provided as a spun yarn (or roving) generally comprising a large number (of (he order of several hundreds) of individual fibers of a diameter of several microns, these fibers all being side by side and, therefore, substantially parallel to each other, except for a few overlaps.

- Other materials may be suitable for the construction of the filament as well.
- Resin 175 is preferably selected so as to provide sufficient cohesion between the textile fibers so as to avoid rapid collapse in compression following micro-buckling of the fibers in resin 175.
- resin 175. For example, vinyl-ester or epoxy resins can be used.
- Other resins providing the required mechanical properties for reinforcing structure 160 may also be used.

Together, the multiple plies of support band 180 can provide a triangulated reinforcement which, under the various stresses that it experiences, undergoes very little deformation. Constructions that maybe used for support band 180 are set forth eg., in U.S. Pub.
- FIG. 4 illustrates another exemplary embodiment of tire 100 of the present invention also having a reinforcement structure 160.
- reinforcing structure 160 has a circumferential extension modulus of about 5 GPa or greater and an axial plane shear modulus of about 10 MPa or greater.
- reinforcement structure 160 in FIG. 4 includes a plurality of layers. More particularly, reinforcement structure 160 includes layers 165, 195, and 200. Each such layer is constructed from at least one filament wound about the axial direction as previously described for layer 165.

- support band 180 may be directly adjacent or in contact with layer 165.

- an overall thickness of at least about 1 mm to about 5 mm for structure 160 may be used, although other thicknesses may be used as well.
- FIO. 6 presents certain data from a simulation designed to explore the effectiveness of an embodiment of the present invention. More particularly, FIO. 6 provides a plot, for various loads, of the ratio of stiffness along the radial direction of a tire constructed with a reinforcing band 160 of the present invention to a reference tire not having reinforcing band 160. As shown, the stiffness of reinforcing band 160 allows tire 100 to operate at a lower deflection, which can improve durability and/or increase load capacity. By way of further example, at the maximum loading condition shown, the simulation projects a stiffness increase of 26 percent while deflection is reduced by 7.7 mm.
