摘要： This disclosure relates to a tire including a spiral cord layer and core-material cord layer arranged between an upper and lower layer of spiral cord layer in a tire crown portion, both the occurrence of groove cracking and occurrence of separation from width-direction end of core-material cord layer can be suppressed. The tire can include carcass which toroidally extends between pair of bead portions; spiral cord layer which is arranged on tire radial-direction outer side of carcass in crown portion and in which an upper and lower layer are formed by spirally winding reinforcing cord; and core-material cord layer which is arranged between upper and lower layer of spiral cord layer. The reinforcing cord of spiral cord layer are composed of carbon fibers, and core-material cords of core-material cord layer have an angle in a range of 0° to 50° with respect to a tire circumferential direction.

摘要： The invention relates to a pneumatic vehicle tire having two or more belt plies which have reinforcement members crossing one another at an angle, wherein the reinforcement members within each belt ply are arranged substantially parallel to and spaced apart from one another and are embedded in rubber material, wherein the belt has at least one first belt ply, the reinforcement members of which are formed by steel monofilaments of the reinforcement member class Ultra-Tensile (UT) with in each case a tensile strength of 3080 N/mm2 to 4190 N/mm2, wherein the steel monofilaments have a diameter D of 0.33 mm to 0.37 mm. It is the object of the invention to provide, at lower cost, a pneumatic vehicle tyre with low rolling resistance, by way of simultaneously simplified production. This is achieved in that the steel monofilaments have a torsion value of approximately zero windings in the case of a length dimension of 200 times the diameter of the steel monofilament.

摘要： A pneumatic tire includes a carcass, a tread portion and a belt layer having a first inclined belt ply, circumferential direction belt ply, and second inclined belt ply. Ground contact edge side belt plies extend from tire width direction end portions of the second inclined belt ply toward tire width direction outsides, at a tire radial direction outside of the carcass. With respect to a tire circumferential direction, an angle of cords of the first inclined belt ply is from 45° to 60°, an angle of a cord of the circumferential direction belt ply is 5° or less, an angle of cords of the second inclined belt ply is from 30° to 60°, and an angle of cords of the ground contact edge side belt plies exceeds 5° and is 30° or less. A distance dimension of the ground contact edge side belt plies is 80% or more of a ground contact width.

摘要： In one aspect, a method provides a reciprocating bolt by a bolt assembly having a bolt assembly body, a cap affixed to the bolt assembly body, and a base affixed to the bolt assembly body opposite the cap. The method includes biasing a bolt carrier in the bolt assembly body in a retracted position relative to the bolt assembly, resulting in a center portion of a diaphragm disposed between the cap and the bolt assembly body being deflected toward the cap. The method also includes applying an actuation force to the bolt carrier so as to move the bolt carrier from the retracted position to an extended position relative to the bolt assembly by oppositely deflecting the center portion of the diaphragm toward the base, and discontinuing the applying of the actuation force while the bolt carrier is in the extended position.

摘要： A manufacturing apparatus of a rubber sheet containing a steel cord, including a feeding device which feeds the steel cord while keeping a specified tension; a forming device which winds the steel cord being fed by the feeding device around engagement parts spaced from each other with a predetermined width; and a placement device which places on a rubber sheet member, the steel cord wound around the engagement parts with the predetermined width. The forming device includes forming parts which press bent portions of the steel cord wound around the engagement parts to form a bending shape of the bent portions, and the placement device includes a plurality of retaining parts disposed in two rows spaced apart from each other with the predetermined width to retain the bent portions in a state in which the steel cord having the bending shape is placed on the rubber sheet member.

摘要： The pneumatic tire includes a carcass layer, a belt layer disposed outward of the carcass layer in the tire radial direction, and a tread rubber disposed outward of the belt layer in the tire radial direction. Moreover, the belt layer is formed by laminating a pair of cross belts having a belt angle with an absolute value from 10° to 45° both inclusive and mutually opposite signs, and the circumferential reinforcing layer having a belt angle within a range of ±5° relative to the tire circumferential direction. Moreover, the distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10≤Gsh/Gcc.
