摘要:
A method and apparatus are disclosed for flatproofing a tire and wheel assembly (208) with a flexible, lightweight foam-fill by supplying at least two polyurethane reactive materials to a static mixer (116). The static mixer mixes the reactants, and a nucleating gas is supplied to the mixed reactants in the static mixer to form a liquid reactant mixture with entrained gas. The reactant mixture is injected into the tire and wheel assembly where the mixture reacts and foams replacing the air in the tire with a flexible, lightweight semi-open cell foam-fill. The resulting foam-filled tire and wheel assembly is then allowed to cure.

A semi-pneumatic tire assembly including a tire casing (22) and a lining (26) is provided. The lining (26) includes a contoured inward surface (30) defining an inflation chamber (18) about an associated wheel rim. The lining (26) minimizes the risk of puncture damage from an object penetrating the tire casing (22) while allowing pneumatic cushioning of the ride and cooler running temperatures as compared to solid-fill tires. Additionally, the semi-pneumatic tire will carry the same load or more than the same tire filled with permafoam and/or solid urethane foam wingfil. The tire assembly is formed by injecting a curable, lining-forming material (96) into a cavity (57) defined between the tire casing (22) and a molding member (50). The molding member (50) includes a contoured outer surface (54) which molds the inward surface of the lining (26). The molding member (50) may be an inflatable airbag (100) retained in the tire assembly during service. Alternately, the molding member (50) may be a solid core (114) which is removed prior to mounting the tire casing (22) and lining (26) on the associated rim.

An auger for a grinder material for a tire filling machine, having: a cylindrical column; and a plurality of flights extending outwardly from the cylindrical core, wherein (i) the flights are arranged in pairs extending radially outwards from the cylindrical column at 180 degrees to one another, and (ii) each flight has a sharpened leading edge. Each pair of flights are positioned at angles of approximately 50 or 60 degrees to one another, and each flight extends approximately half way around the circumference of the cylindrical column, and there are no outer edge notches in the flights.

The present invention relates to a tire structure which is used for a power generation system using tire deformation and is formed by coupling, to an inside of a tire, spikes operated in conjunction with deformation of a tire. More particularly, the present invention relates to a tire structure having spikes coupled thereon, the tire structure including: a tire; an attachment layer positioned between an inner surface of the tire and a spike supporting layer, and allowing the spike supporting layer to be coupled to the inside of the tire; and a spike supporting layer coupled to the inside of the tire by the attachment layer and supporting the spikes operated in conjunction with deformation of the tire, thereby enabling an existing tire to be used for the power generation system using tire deformation.
摘要:
A mold (16) for molding a foamed tube for a tire of the present invention is formed from a first mold (16A) and a second mold (16B). Each mold has an annular concave portion (18A,18B) for tube molding, and joining faces (24,25,26,27) which are continuous with the annular concave portion and are formed at an inner side and an outer side, in a radial direction, of the annular concave portion. Each of the joining faces (24,25) of the first mold and the joining faces (26,27) of the second mold has horizontal joining faces (24A,25A,26A,27A) provided adjacent to the annular concave portion in a direction orthogonal to an axial direction at a radially inner side and a radially outer side of the annular concave portion, and an inclined joining face (24B,25B,26B,27B) provided continuously with the horizontal joining face so as to be inclined with respect to the horizontal joining face at one of an inner side and an outer side in the radial direction.

Verfahren zur Herstellung eines notlauffähigen Fahrzeugrades, bestehend aus einer Felgenhörner und ein Felgenbett aufweisenden Felge und einem luftgefüllten, im wesentlichen aus Gummi oder einem ähnlichen Elastomer bestehenden Fahrzeugreifen. In den Fahrzeugreifen ist ein mit einer Schaumfüllung ausgeschäumter Innenreifen als Notlaufstützkörper eingelegt. Es wird eine einteilige Felge verwendet, in deren Felgenbett ein schlauchförmiger Innenreifen aus Gummi in drucklosem Zustand eingelegt wird. Der Reifen wird über den drucklosen schlauchförmigen Innenreifen hinweg auf die Felge aufgezogen und die Schaumfüllung wird nach der Montage des Reifens in den schlauchförmigen Innenreifen eingefüllt.
摘要:
A toroidal semifinished product (5) made of raw elastomeric material is semivulcanized in a semivulcanization chamber (4) defined between two half-moulds (2, 3) disposed close to each other. The same pressure as that exerted by the gases generated in the semifinished product (5) is created in the mould (1a). The half-moulds (2, 3) are moved apart from each other and pressure in the mould is gradually reduced, thereby giving rise to the expansion and consequent transferring of the semifinished product (5) from the semivulcanization chamber (4) to a surrounding final vulcanization chamber (6). When the inner diameter of the semifinished product (5) is larger than the inner diameter of the final vulcanization chamber (6), said chamber is closed at its inner circumferential edge and then, after possible pressure increase in the mould, at its outer circumferential edge, in order to integrally enclose the semifinished product and enable completion of the vulcanization process.
