20090272471 | SYSTEM FOR BALANCING A TIRE - The present invention is directed to a machine for balancing a pneumatic tire/wheel assembly and the balanced pneumatic tire. The pneumatic tire comprises an axis of rotation, a belt structure, an innerliner disposed radially inward of the belt structure, and two annular beads for securing the tire to a wheel. The tire includes an annular spacer structure and a thixotropic gel. The annular spacer structure is attached to the innerliner and is disposed radially inward of the belt structure. The annular spacer structure defines two interior circumferential grooves between axially outer sides of the annular spacer structure and portions of the innerliner extending radially inward toward the corresponding beads of the tire. The thixotropic gel is disposed within the circumferential grooves thereby defining two circumferential gel rings. The gel of each circumferential gel ring automatically, upon rotation of the tire, flows until no more forces, except direct centripedal forces, act on the gel such that the tire is rotationally balanced. | 11-05-2009 |
20100006195 | TYRE WITH INNER SURFACE PROVIDED WITH A NANOSTRUCTURE - The invention relates to automobile tyres or tyre assemblies or parts thereof suitable for being balanced by introduction therein of a thixrotropic balancing gel, wherein surfaces of the tyre or tyre assembly or part thereof which are intended to be in contact with the balancing gel are provided with a surface nanostructure with an average surface roughness in the range of 1-1000 nm. The surface nanostructure will enable the thixotropic balancing gel to move to the location, where it balances the tyre, significantly quicker than if the surface in question did not have the surface nanostructure. | 01-14-2010 |
20100043932 | WEIGHT FREE TIRE BALANCING SYSTEM - An improved apparatus, system and method of balancing a tire for a vehicle is provided. In an exemplary embodiment, a new tire for a vehicle is provided wherein the tire incorporates a plurality of removable portions and/or attachments that may be removed from their position on the external portion of the tire to properly balance the tire about the wheel assembly. Further, a system and method is provided that may be employed to properly balance the tire without the necessity of adding metal or other type weights to the wheel and tire assembly. | 02-25-2010 |
20100059154 | APPARATUS AND METHOD FOR DISPENSING VEHICLE BALLASTING WEIGHTS - An apparatus for and a method of dispensing a vehicle ballasting weight for balancing a portion of a vehicle. The method comprises dispensing a vehicle ballasting weight material comprising a flexible polymeric matrix material filled with a high density particulate material, and severing an incremental length of the vehicle ballasting weight material from an initial length of the weight material, where the incremental length can correspond exactly to a desired mass for the vehicle ballasting weight. | 03-11-2010 |
20100101692 | COMPOSITION FOR CORRETING FORCE VARIATIONS AND VIBRATIONS OF A TIRE-WHEEL ASSEMBLY - The present invention comprises apparatus and methods for improved correction of force variations and/or frequencies of a tire-wheel assembly. In particular embodiments, the invention comprises a system for improved correction of force variations and/or dampening of vibrations in a pneumatic tire-wheel assembly, which includes: a pneumatic tire-wheel assembly; and a plurality of dampening particles positioned within the tire-wheel assembly, wherein said particles are formed of at least one energy dampening viscoelastic material. In other embodiments, the present invention comprises a method for improved the equalization of force variations and vibrations of a pneumatic tire-wheel assembly comprising the steps of: providing a pneumatic tire-wheel assembly; providing a plurality of impact dampening particles, wherein the particles are formed of at least one energy dampening viscoelastic material; and, placing said plurality of particles in free movable relationship into a pressurization chamber within said tire-wheel assembly. | 04-29-2010 |
20100175798 | COMPOSITION FOR CORRECTING TIRE-WHEEL IMBALANCES, FORCE VARIATIONS, AND VIBRATIONS - Particular embodiments of the present invention include methods and compositions for improved correction of force imbalances, force variations, and/or dampening of vibrations in a tire-wheel assembly. In particular embodiments, the composition includes a plurality of particles for positioning within a pressurization chamber of the tire-wheel assembly, wherein said particles include a void. Further embodiments provide a void containing a tire balancing material or a viscoelastic material. The particle may also be formed of viscoelastic material. Methods of the present invention include the steps of: providing a tire-wheel assembly; providing a plurality of particles having a void; and placing said plurality of particles into a pressurization chamber within said tire-wheel assembly. | 07-15-2010 |
20120024439 | PNEUMATIC TIRE - A pneumatic tire including a separatable pair of mechanical fasteners wherein a first fastener of the pair of mechanical fasteners is provided on a tire inner surface. In this pneumatic tire, the obtained engagement force of the pair of mechanical fasteners is great and is essentially free of variations (positional variation within the tire and variation from tire to tire); the engagement force deteriorates/declines minimally over time due to extreme usage conditions including repetitive deformation and compaction over an extended period of time caused by tire rotation at high speeds in a state of relatively elevated temperatures; and the desired engagement force can be maintained over an extended period of time. | 02-02-2012 |
20120097299 | AUTO-BALANCING TIRE - A pneumatic radial tire includes a carcass, opposing bead portions, a carcass reinforcing ply extending between the bead portions, and opposing bead cores situated within respective opposing bead portions. An annular hollow tube member is situated within a bead portion, the tube member containing within a tube internal passageway a viscous fluid and a plurality of spherical balls within the viscous fluid. The spherical balls are dimensioned and sized to freely move circumferentially about the tube passageway. The balancing bodies operationally reposition within the tube passageway to cancel imbalance effects within a running wheel assembly including the tire. The tube member may be located in a tire apex member or form a tire bead core within the tire bead portion with carcass reinforcing ply endings surrounding the tube member. | 04-26-2012 |
20120111462 | Self-Balancing Pneumatic Tire and Method of Making the Same - A self-balancing pneumatic tire is provided having a built-in balancing gel system. In one embodiment, the tire, before cure, includes a green pneumatic tire assembly having an uncured tread defining an outermost layer; a first barrier layer; a second barrier layer situated adjacent the first barrier layer and intermediate the first barrier layer and the tread; and first and second gel precursors. The gel precursors are non-flowable prior to cure but flowable after cure. The gel precursors are respectively contained within spaced-apart first and second circumferential regions defined by confronting, non-contacting surfaces of the first barrier layer and the second barrier layer, each circumferential region further situated proximate opposing sidewalls of the tire and having a width of about 5 percent to about 25 percent of a final tread width obtained upon curing of the uncured tire assembly. In one example, the first and/or second barrier layers can be discontinuous. | 05-10-2012 |
