摘要:
The invention relates to a pneumatic vehicle tire (1) comprising two bead wires (2) which are configured in the radially lower section of a tire sidewall, a carcass (3) which is constituted of one or more carcass layers of parallel reinforcements and which extends from the bead wire (2) of the first tire sidewall (11) through the tire crown section (5) to the bead wire (2) of the second tire sidewall (11), a belt (6) of one or more belt layers which extends in the tire crown section (5) across the entire circumference of the tire and in the axial direction from tire shoulder to tire shoulder, and a profiled tread (7). A single rubber layer (13) of a rubber material extends in the peripheral direction of the tire across the entire circumference of the tire while forming the tire surface on the inner side of the pneumatic vehicle tire and covers the carcass (3). Said rubber layer (13) extends on the radial inner side of every bead wire (2) axially outwards to the axial outer side of the tire and is designed so as to extend on the axial outer side of the tire while forming the tire surface towards radially outwards through the tire sidewall (11) along the carcass (3) while covering the carcass (3) towards the axial outer side of the vehicle tire to the tire shoulder.

A tire casing (302) is formed on an annular toroidally shaped building surface. The tire casing 302 has a cord attachment elastomeric layer (250) extending over the toroidally shaped building surface to a pair of radial inner ends (32R); a first and second bead stack (220), each bead stack (220) having an axially inner stack (222) and an axially outer stack (224) the axially inner stack (222) attached to one of the radial inner ends (32R) of the first elastomeric layer (250); one or more continuous lengths of first ply cords (32A), and one or more continuous lengths of second ply cords (32B). The one or more continuous lengths of the first ply cords (32A) in combination with the one or more continuous lengths of the second ply cords (32B) form a bias angled cord reinforced belt structure, the first ply cords (32A) forming one cord reinforced sidewall and the second ply cords (32B) forming an opposite cord reinforced sidewall.

A pneumatic radial tire has a nominal section width of 255 mm or more, and an outer diameter of 720 mm or more. At least one carcass layer (6) is constructed between paired right and left bead cores (4) with the two end portions of the carcass layer (6) being folded back from the inside to the outside of the tire around the respective bead cores (4) in a way that their corresponding bead fillers (5) are enclosed in the two folded end portions thereof. The length of each bead filler (5) in the radial direction of the tire is 5% to 20% of the section height of the tire. The carcass layer (6) is formed of organic fiber cords each made of at least one type of organic fiber which has an expansion ratio of 1% to 5% when a load of 2.0cN/dtex is applied to the organic fiber. A sheet-shaped rubber reinforcement layer (7) with a thickness of 0.5 mm to 2 mm, whose rubber has a larger rigidity than that of the sidewall section (2), is interposed between the carcass layer (6) and a sidewall section (2) on each side of the tire.
摘要:
Die Erfindung betrifft einen Fahrzeugreifen mit einem Laufstreifen, einem Gürtel (4), Seitenwänden (13), Wulstkernen (5) mit einem Kernprofil (6) und mit mindestens zwei Einlagcn(2) mit Festigkeitsträgern. Um einen Fahrzeugreifen mit einem Reifenmodul bereitzustellen, bei dem bei einem Mehrlagenreifen ein zu breiter Wulst vermieden wird, wird vorgeschlagen, dass die erste und die zweite Einlage (1,2) dergestalt außermittig von der radialen Mittelachse (3) des Fahrzeugreifens positioniert sind, dass sowohl ein Ende der ersten Einlage (1) als auch ein Ende der zweiten Einlage (2) auf jeder Wulstseite jeweils nur einen Wulstkern (5) umschlingen und die jeweils gegenüberliegenden Enden (9,10) bis maximal im Bereich neben dem Wulstkern (5) auf der Reifeninnenseite (11) reichen.
摘要:
A tire (2) comprises a tread (4), a sidewall (6), a bead (8), a carcass (10) and a belt (12). The belt (12) includes a belt ply (26). The belt ply (26) is formed by a ribbon (28) wound spirally in a circumferential direction of the tire (2). The carcass (10) includes a first carcass ply (22) and a second carcass ply (24) provided on an outside in a radial direction of the first carcass ply (22). The first carcass ply (22) is turned up around the bead (8). The first carcass ply (22) includes a turned-up portion (34) extended almost outward in the radial direction and a turned-up end (36) positioned on an outside in the radial direction of the turned-up portion (34). The turned-up end (36) is positioned on an inside of the second carcass ply (24).
