    摘要: A radial tyre for motor vehicle includes: a crown with at least a tread and a crown reinforcement or belt, two inextensible beads, two sidewalls connecting the two inextensible beads to the tread, and a carcass reinforcement passing into the two sidewalls and anchored in the two inextensible beads. The belt is positioned circumferentially between the tread and the carcass reinforcement, and includes textile or metallic reinforcers coated with a rubber composition referred to as a “belt-coating rubber.” The belt-coating rubber, which is capable of reducing the tyre's rolling noise, includes a diene elastomer and more than 50 phr of a filler of high-density particles having a density of greater than 4 g/cm3.

    摘要: A heat-expandable rubber layer is provided to an inner all of a pneumatic tyre when the tyre is in an uncured state. The rubber layer is expanded when the tyre is in a vulcanized state. Once expanded, the rubber layer is capable of reducing rolling noises of the tyre. The rubber layer includes an elastomer composition based on at least an elastomer, e.g., natural rubber or butyl rubber; a reinforcing filler, e.g., silica and/or carbon black; between 10 and 80 phr of a blowing agent, e.g., an azodicarbonamide compound; and between 10 and 50 phr of a hot-melt compound with a melting point between 70° C. and 150° C., e.g., urea. The combination of the blowing agent and the hot-melt compound, at recommended high contents, makes it possible to very greatly reduce an expansion ratio and therefore a thickness of the rubber layer once the pneumatic tyre is vulcanized, without affecting noise absorption properties provided by the blowing agent.

    摘要: A radial tyre for reducing rolling noise includes a tread with a contact part located at a radially outer position to make contact with the road, two inextensible beads, two sidewalls connecting the beads to the tread, a carcass reinforcement, a belt arranged circumferentially between the radially outer part of the tread and the carcass reinforcement, and an inner crown layer located at a radially inner position. A formulation of the inner crown layer is different from a formulation of the contact part of the tread, and includes: 50 to 100 phr (parts by weight per hundred parts of elastomer) of a copolymer based on styrene and butadiene with a glass transition temperature of greater than −10° C., a reinforcing filler, and a crosslinking system.

    摘要: A radial tyre for a motor vehicle includes a crown, two beads, a crown reinforcement, and an inner crown layer. A tread of the crown includes a contact part located at a radially outer position and intended to make contact with a road surface. The inner crown layer is located at a radially inner position and is formed of an elastomeric material having a different formulation from that of the contact part of the tread. The inner crown layer is arranged circumferentially between the contact part of the tread and the crown reinforcement or between the crown reinforcement and a carcass reinforcement, and functions to reduce rolling noises of the tyre. The elastomeric material includes a rubber composition with at least: 50 to 100 phr of a copolymer based on styrene and butadiene with a Tg greater than −40° C., a reinforcing filler, a hydrocarbon-based plasticizing resin, and a crosslinking system.
