Abstract:
A system for dissipating sound shock waves within a vehicle tire includes a wheel upon which a tire is mounted to create an internal air chamber defined by the wheel and the tire. A flow-resistant barrier is coupled to the wheel or the tire and defines an air cavity within the internal air chamber. The barrier comprises a material that provides an acoustical resistance to sound shock waves passing therethrough. The air cavity defined by the barrier has a volume such that air within the cavity offers relatively small impedance to the passage of shock waves through the barrier and into the air cavity. The barrier also can produce frictional heat when displaced by a shock wave, thereby converting energy of the shock wave to heat to reduce noise associated therewith.
Abstract:
An inner-tube divided into many isolated cells of air. Two tubes on inside circumference of said inner-tube, one for inflating air and the other for deflating air. Each cell has two one-way valves, one for filling air and the other for extracting air. The inflating valve could have an observation window or an air pressure gauge attached to it for indicating when there is a puncture in one or more of the cells of air in the inner tube.
Abstract:
Disclosed is a tire/wheel assembly allowed to still further enhance run-flat durability thereof with a simple configuration. A tire/wheel assembly of the present invention is a tire/wheel assembly where a run-flat support member inserted, coaxially with a rim, in a cavity portion of a pneumatic tire. The tire/wheel assembly is formed of a configuration where a retention groove for lubricant on an inner peripheral surface of the pneumatic tire is provided in a manner that the retention groove is faced at least to an apex of the run-flat support member.
Abstract:
An improved tire provides an air-flow restrictor that may be installed inside a tire. The air-flow restrictor may restrict or prevent the flow of air in the direction opposite to the direction of rotation of the tire. Also, a method for saving fuel by inserting or retrofitting tires with air movement restricting inserts.
Abstract:
The invention is a light weight composite tire for use on multipurpose vehicles. The first of the tire is divided into chambers by laminated bulkheads which adds strength. The tire could be used on all terrain vehicles such as a rescue vehicle that requires light weight and the ability to be used on thin ice, mud, slush, swamps, marshes, rivers etc.
Abstract:
The invention is directed to a high-speed, puncture proof tire including a tire casing having a tread portion and a pair of side wall portions and a plurality of small diameter pressurized tubes disposed within the tire casing. Each pressurized tube has an elongate body fabricated from film material that is sealed crosswise along the length of the body to define at least two compartments that contain gas under pressure. The tubes can be oriented radially or circumferentially within the annular space of the tire casing. In another embodiment of the tire, at least one panel of film material resistant to shear forces is disposed within the annular space of the tire casing. The panel is sealed lengthwise thereof to define a plurality of small diameter pressurized tubes. Each pressurized tube is sealed crosswise along the length of the tube to define at least two compartments that contain gas under pressure.

Abstract:
A segmented tire for resisting complete deflation after being punctured. The segmented tire includes a tire having an inside wall and an outside wall. An outer peripheral wall extends between and is integrally coupled to an outer edge of the inside wall and the outside wall. Each of the inside and outside walls has a generally circular shape and has a central area having a circular opening therein. An inner peripheral wall extends between and is integrally coupled to an edge of each of the openings such that a generally airtight interior of the tire is defined. Each of a plurality of intermediate walls is positioned within the tire. Each of the intermediate walls extends between and is attached to the inner peripheral wall and the outer peripheral wall such that the intermediate walls radiate outwardly from the inner peripheral wall to the outer peripheral wall. Each of the intermediate walls extends between the inside wall and the outside wall such that each of a plurality of substantially air-tight chambers is defined between a pair of adjacent intermediate walls. The tire and the intermediate walls comprise an elastonmeric material.
Abstract:
The present invention is a pre-pressurized in-line skate wheel which is capable of being pressurized at low levels and which further includes an integral bladder device having an annular tube and three bladder rods which are in fluid communication with respect to each other. The wheel is configured with a rigid polyurethane hub formed with a drop center and further having a pair of radially extending flanges with three pairs of axial openings. The hub is further formed with three radially projecting spokes. The tire body surrounds the bladder device and is constructed of a generally more resilient polyurethane which bonds to the hub, flanges and bladder. The method of manufacture utilizes blow molding techniques for the bladder device which includes a post vulcanization chlorine bath. The tire body is formed using liquid thermoset polyurethane poured into an open cast mold. The resulting wheel ensures the rider of a long lasting, light weight tire with exceptional shock absorption properties to therefore provide a smooth and comfortable ride.
Abstract:
Disclosed is a pressurizable inner multi chambered tube for a tire having resilient radial walls in the body sealingly the chambers from one another. A ring shaped manifold on the tube communicates to the chambers by a check valve at each chamber, the check valves permitting fluid flow from the manifold to the chambers but preventing flow in the reverse direction. A valveless fluid passing fixture on the manifold permits the manifold to be connected to a source of pressurized air. If one chamber of the tube looses pressure, the remaining tubes will expand in an angular, circumferential direction and slide on the manifold so as to take up space formerly occupied by the one, depressurized chamber. The check valves of the remaining chambers will be released from engagement as the remaining chambers slide on the manifold.
