摘要： This invention is based upon the unexpected finding that a hydrocarbon traction resin can be dispersed into the oil used in making an oil extended emulsion and solution rubbers to attain improved performance characteristics. For instance, this technique allows for the hydrocarbon traction resin to be incorporated into the rubber at a higher level than would ordinarily be possible using conventional mixing techniques. In tire tread compounds this provides improved wet traction characteristics without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). This technique can be used to incorporate a resin into virtually any synthetic rubber that can benefit from being oil extended. It is of particular value in making resin modified solution styrene-butadiene rubber (SSBR), emulsion styrene-butadiene rubber (ESBR), high cis-1.4-polybutadiene rubber, and synthetic polyisoprene rubber which are formulated for use in tire tread compounds.

摘要： It has been unexpected found that silylated triglyceride oils can be incorporated into tire tread rubber formulations that include reinforcing fillers to provide improved wet traction characteristic, rolling resistance, and tread-wear without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). The level of silica coupling agent needed in such formulation can also typically reduced. The present invention more specifically discloses a rubber formulation which is comprised of (1) a rubbery polymer; (2) a reinforcing filler, such as silica or carbon black; and (3) a silylated triglyceride oil. The silylated triglyceride oil will include silyl groups of the structural formula: —(CH2)n—Si(OR)3, wherein n represents an integer within the range of 1 to 8, and wherein R represents an alkyl group containing from 1 to 8 carbon atoms.

摘要： A non-pneumatic tire is described that includes a ground contacting annular tread portion, a shear band, wherein the shear band is formed of a first and second inextensible layer, and a low modulus material positioned between the first and second inextensible layer. The non-pneumatic tire further includes a connecting web positioned between a hub and the shear band, wherein the connecting web is formed of one or more spokes extending from an inner ring to an outer ring, wherein the one or more spokes are formed from a material reinforced with a three dimensional spacer structure.

摘要： A self-inflating tire assembly includes an air tube mounted within a tire sidewall groove. The air tube is in contacting engagement with opposite angled groove surfaces surrounding the air tube. A segment of the air tube is flattened from an expanded diameter to a flat diameter by bending and compression of the groove in a rolling tire footprint to force air evacuated from the flattened segment along a tube air passageway. The sidewall groove extends into an annular, axially extending, sidewall surface such as an axially oriented surface of a tire chafer protrusion located in non-contacting relationship with the rim. The opposite groove surfaces comprise a rubber composition, the rubber composition comprising: a diene based rubber; from 0.25 to 5 parts by weight, per 100 parts by weight of rubber (phr), of a self-lubrication agent capable of migrating from the rubber composition to the groove surface and disposing on the groove surface as a liquid; and from 1 to 15 parts by weight, per 100 parts by weight of rubber (phr), of a vulcanization modifier for use in the second rubber composition include α,ω-bis(N,N′-dihydrocarbylthiocarbamamoyldithio)alkanes, bismaleimides, and biscitraconimides.
