摘要:
This invention relates to pneumatic tires and more particularly to a so-called safety tire comprising a carcass having a tube accommodated therein and spaced from the carcass to form inner and outer air chambers. A loose, circumferentially extending, puncture-resistant band is positioned substantially in the mid-circumferential plane of the tire between the underside of the tire tread and the tube. A further feature of the invention is the provision of means which produces an audible signal should the outer chamber become deflated. Another feature of the invention is the provision of means which, in use, limit radial and/or axial expansion of the tube should the outer chamber become deflated. A final feature is the provision of means which inhibit or prevent removal of the bead portions of the tire. from their respective seats upon deflation of the tire.

A tire has a succession of peripherally arranged compartments. The compartments are interconnected by separate passages via one-way check valves for inflating the compartments through one passage and deflating them through another. The passages are both connected to a main valve which enables the passages and thereby the compartments to intercommunicate at least during inflation or deflation but separates the passages and thereby the compartments otherwise.

A vehicle tire casing and inner inflated tubular member of material comprising lead (or optionally other highly malleable metal having high ductility in the range of that of lead and copper, and substantially pure aluminum and tin). Lead, which may be flexed many thousands of times without fracture, is resistant to puncture and may be welded by simple heating without flux, is preferred; when copper, aluminum or tin is used the tubular member is sheathed in and flexibly bonded to a thin-rubber envelope. The invention comprehends a doughnut-shaped lead inner tube; but optionally the tubular member comprises annularly arranged tubular elements, each having a middle portion of greatest inflated bulge, from which portions curvingly slope to wider constrictions at ends of the elements. These constrictions may be: flattened, hermetically bonded plies of the tubularmember material; or only substantially flat, having lines of seam or spot welding, allowing passage of gas between the welds. The invention includes a wheel, having laterally projecting flanges, inward of which casing flanges are held.

An inner tube assembly for a pneumatic tire is disclosed. The assembly includes a pair of inner tube systems, one of which surrounds the other and intercommunicates therewith via a valve unit that is adapted to allow a pneumatic fluid to flow unidirectionally from the inner one of such tube systems to the outer one of said tube systems and effect an equilibrium of pressure. The valve unit, however, is adapted to close when the outer one of such tube systems is punctured and undergoes a pressure drop relative to the inner one of such tube systems, thereby to pneumatically isolate the interiors of such tube systems from one another.

An arrangement for securing the beads of a pneumatic tire in the rim therefor, according to which an annular inflatable body is located in the interior of the beaded pneumatic tire which inflatable body in non-inflated or in only slightly inflated condition has an inner diameter greater than the diameter defined by the seating surfaces of the tire. The annular inflatable body has two reinforcing layers respectively including thread-shaped elements inclined in a left hand and right hand way so as to cross each other. The arrangement is such that in non-inflated condition of the inflatable body the thread-shaped elements form with the circumferential direction of the tire an angle of from approximately 23.degree. to 32.degree..

A wheel having an inflatable tire and designed to be used on automobiles, airplanes, trucks, and the like. The tire has an outer wall provided with an outer tread surface and surrounding a predetermined axis, this outer wall having a pair of opposed side edge regions from which a pair of side walls extend integrally from the outer wall inwardly toward the axis and terminate in inner peripheral edges which surround the axis. An intermediate wall is integral with the outer wall and is situated between and spaced from the side walls, also extending inwardly toward the axis so as to define with the outer walls a pair of air chambers which are separated from each other by the intermediate wall. The wheel includes a suitable mounting structure on which the tire is mounted in such a way that fluid-tight seals are provided at the inner peripheral edges of the side and intermediate walls. In this way if the tire should become punctured or lose air pressure for any reason at one of its chambers it will still be capable of providing fully operative service as a result of the air pressure in the other of its chambers.

A pneumatic insert for a pneumatic tire comprises a generally toroidal shaped hollow member having a pair of annular insert beads with sidewalls extending therefrom joined to an insert crown portion. An annular flap portion is joined to the outer surface of each insert sidewall at the bead area and extends beyond each bead a predetermined amount.The pneumatic insert is disposed in a standard tire and mounted on standard rim. The insert flaps are tucked between the respective insert beads and the bead support surface of the rim to provide a leak-tight seal. When the insert is inflated the insert beads push the respective tire beads against the rim flange. In one embodiment the tire is inflated through an air passage member disposed between the tire and insert beads. In another embodiment the tire is inflated directly through the tire sidewall with a hypodermic needle. The insert inflation chamber and the tire inflation chamber do not communicate and can be inflated to different pressure levels.Other embodiments of the pneumatic insert include fabric reinforcements and/or protective caps.

A pneumatic tired wheel having excellent highspeed performance after puncture comprises a tubeless tire, a bead stopper and a rim. The tubeless tire comprises a pair of elastic reinforcements having a Shore A hardness of at least 47, the bead stopper comprises an independent air-tight chamber and a crown portion with at least one inextensible reinforcing layer. The crown portion has an outer diameter determined in connection with the outer diameters of the flange of the rim and the tread portion of the tire.

The present invention comprises a complete suspension system for multiple axle vehicles, including a single axle suspension structure, a tandem axle suspension structure wherein road and tire excitations of each axle are isolated from the opposing axle and from the sprung mass or vehicle frame, and a third structure interconnecting the tandem axles with articulated load equalizing rocker beams which are separately trunnioned in the suspension structure supported by said tandem axles. Both the single axle and the tandem axle suspension structures employ spherically shaped, pressure resistant, elastomeric spring means formed with cup shaped seats which, in turn, exhibit a varying spring rate upon said elastomeric spring means being subjected to load.

PUNCTURE PROOF OR UNDERFLATABLE TIRE WHICH MAY BE OF THE TUBED OR TUBELESS VARIETY BUT IN EITHER EVENT PROVIDED WITH A PLURALITY OF SUBSTANTIALLY AIR-TIGHT CELLS ADJACENT A MANIFOLD WHICH IS ADAPTED TO HAVE A NORMAL INLET FROM THE EXTERIOR OF THE TIRE THROUGH A TIRE VALVE WHICH MAY PASS THROUGH THE WHEEL RIM AND WHEREIN THE MANIFOLD IS CONNECTED TO EACH OF THE CELLS THROUGH A VALVE WHICH PERMITS AIR TO PASS THROUGH THE MANIFOLD TO A CELL WHEN THE PRESSURE OF A PARTICULAR CELL HAS CRITICALLY DROPPED DUE TO A PUNCTURE OF A RUPTURE OF A WALL THEREOF. THE TIRES IN ACCORDANCE WITH THE INSTANT INVENTIONALLY ALSO INCLUDE A SPECIAL VALVE LOCATED BETWEEN EACH CELL IN THE MANIFOLD OF SUCH NATURE AS WILL PERMIT AIR FROM THE MANIFOLD TO BE PASSED TO A CELL WHICH HAS LOST AIR AND WILL ALSO PERMIT AIR TO BE PASSED FROM THE CELL BACK TO THE MANIFOLD WHEN THE MANIFOLD PRESSURE HAS BEEN RELIEVED BY OPENING ITS INLET VALVE.
