摘要:
A tire according to the present disclosure includes a carcass comprising a carcass body portion that extends toroidally between a pair of bead cores and a carcass foldback portion that extends from the carcass body portion and folds back around a perimeter of the bead cores from a tire width direction inner side to a tire width direction outer side, and a communication device embedded on the tire width direction outer side of the carcass foldback portion, wherein, when in a standard state in which the tire is fitted to an applicable rim, a prescribed internal pressure is applied, and no load is applied, a cord extension direction of the carcass foldback portion is inclined with respect to a tire radial direction when viewed in a tire width direction.

A tire comprising at least one carcass-type reinforcing structure and comprising a crown reinforcing structure having at least one working layer. At least one working layer is radially on the inside of at least one carcass layer, in the sidewalls, the tire comprises at least two carcass reinforcing layer portions extending over a radial distance at least equal to 50% of the radial distance between an end of a shoulder and the radially inner end of the radially innermost circumferential reinforcing element, at least in the equatorial plane, the reinforcing elements of the carcass reinforcement make an angle less than 80°, and the reinforcing elements of the working layer cross with the reinforcing elements of the carcass-type reinforcing structure by an angle greater than 40°, when the tire comprises at least two working layers radially on the inside of at least one carcass layer, the reinforcing elements of the at least two working layers being crossed by an angle of at most 5° and when the tire comprises at least one working layer radially on the outside of the carcass-type reinforcing structure, the reinforcing elements of the at least one working layer crossing with the reinforcing elements of at least one working layer radially on the inside of at least one carcass layer by an angle of at least 30°.

A heavy duty tire comprises: a carcass ply of cords extending between bead portions; and a bead reinforcing layer disposed in each of the bead portion. The carcass ply has edges winded around the bead cores so that the winded portion has a base part extending along the bead core from the axially inside to the axially outside thereof, and a radially outer part extending axially inwards on the radially outside of the bead core. The bead reinforcing layer comprises: a curved portion extending along the base part; an axially outer portion extending radially outwardly, separation from the base part; and an axially inner portion extending radially outwardly along a main portion of the carcass ply. The bead reinforcing layer is composed of a ply of cords laid side by side, and the spacing Da of the cords in an axially outer part beneath the bead core, of the curved portion is not less than 1.5 times and not more than 3.0 times the spacing Db of the cords in the axially outer portion.
摘要:
A carcass ply producing apparatus for producing a carcass ply constituting a carcass layer of a tire includes a supply head for supplying one or a plurality of ply cords, a head driving mechanism for reciprocating the supply head along a widthwise direction of the carcass ply, a sticking body having a sticking surface to which the ply cord supplied by the supply head is stuck, a sticking body driving mechanism for moving the sticking surface of the sticking body along a longitudinal direction of the carcass ply, and a moving amount controlling mechanism capable of controlling a moving amount of the sticking surface with respect to a moving amount of the supply head. When the ply cord is supplied along the widthwise direction of the carcass ply, a disposition angle of the ply cord with respect to the longitudinal direction can be changed.
摘要:
This invention pertains to a new method for manufacturing tires, an apparatus used with the new method and the article manufactured by the new method. The article is called the reinforced liquid elastomer tire (RLET). The method of manufacture includes placement of reinforcing materials inside a tire molding cavity and subsequently surrounding the reinforcement with a liquid elastomer which encapsulates the reinforcement and takes the outside shape of the tire mold. The liquid elastomer is solidified and the completed RLET is removed from the mold and ready for service.
摘要:
A process for manufacturing, in one stage, a tire comprising a carcass reinforcement (1) which is radial in the sidewalls and oblique radially beneath a crown reinforcement (3), composed of at least two layers (31) and (32) of reinforcement elements (310) and (320) which are crossed from one layer to the next, wherein there is pre-shaped to a diameter D1 and by means of a sleeve of at least one shaping ply N, vulcanized and formed of reinforcement elements forming with the circumferential direction an angle &agr;1, laid on the building drum T of diameter D, at least the central part of a carcass reinforcement ply (1) formed of radial reinforcement elements (10) forming with the circumferential direction an angle ∓&bgr;1. There is laid on the central part at least one crown ply (31, 32) formed of reinforcement elements (310, 320) oriented relative to the circumferential direction at angles ±&ggr;1 (&mgr;&ggr;1), &ggr;1 being little different from &bgr;1. Shaping is effected by bringing the internal diameter D1 of the cylindrical blank to the internal diameter D2, which is the diameter of the vulcanized tire.
摘要:
Tire including at least one carcass reinforcement of at least one ply anchored in each bead B to at least one bead wire, each bead being reinforced by at least two reinforcement plies formed of reinforcing elements inclined relative to the circumferential direction at an angle between 10null and 30null, said reinforcement plies being axially adjacent to the carcass ply wherein the reinforcing elements of at least one ply of the carcass reinforcement, in each part adjacent to the two bead reinforcement plies, are inclined relative to the circumferential direction at an angle between 50null and 80null and are radial in the part located between the radially upper ends of said two reinforcement plies, said ends being located radially outside the sidewall points that define the maximum axial width of the tire when mounted on its intended wheel rim and inflated.
