Embodiment Construction

[0021] figure 1 with figure 2 A commercial vehicle pneumatic tire with a radial structure is shown. The vehicle pneumatic tire has two sidewalls 2 extending in the radial direction R of the vehicle pneumatic tire and a crown region (top region) axially formed therebetween 3. These sidewalls are respectively formed to have a bead region 1 at the extending ends directed inwardly in the radial direction, in which the bead region is formed with an anti-stretching (zugfester) in the circumferential direction U. A bead core 4 of a known type extending on the circumference of the tire. The bead core 4 is formed by coiling a metal wire embedded in rubber extending in the circumferential direction U of a pneumatic tire of a vehicle in a known manner. A horn (Kernreiter) 6 with a triangular cross-section is formed on the bead core 4 by a hard rubber material in a conventional manner. The pneumatic vehicle tire is formed to have a carcass 5 that passes from the bead core 4 formed in t...

Abstract

Vehicle tyres for commercial vehicles, comprising a carcass (5), a belt (9) configured radially outside the carcass (5) and a profiled tread (10) configured radially outside the belt (9) on the belt (9), wherein the belt (9) is formed from at least four belt plies (13, 14, 15, 17) arranged on each other radially from the inside to radially on the outside, wherein the reinforcements (23) of the first belt ply (13) enclose in the alignment thereof an angle of 10° - 45° with respect to the circumferential direction and the reinforcements (25) of the third belt ply (15) in alignment thereof enclose an angle of 10° - 45° with respect to the circumferential direction, wherein as viewed in the circumferential direction (U) of the vehicle tyre the reinforcements (23) of the first belt ply (13) comprise an opposite axial direction of inclination with respect to the reinforcements (25) of the third belt ply (15), and wherein the reinforcements (24) of the second belt ply (14) in the alignment thereof enclose an angle of 0° - 5° with respect to the circumferential direction, characterised in that the reinforcements (27) of the fourth belt ply (17) in the alignment thereof enclose an angle of 50° - 52° with respect to the circumferential direction.

Description

Technical field [0001] The present invention relates to a pneumatic vehicle tire for a commercial vehicle. The pneumatic vehicle tire has a carcass, a cord band constructed radially outside the carcass, and the cord band constructed radially outside the cord band. A shaped tread on a cord, wherein the cord is formed by at least four cord belt layers arranged one above the other from the radially inner to the radially outer, wherein the innermost in the radial direction R The first cord tape layer is formed to have a reinforcing fabric embedded in rubber in parallel, and the second cord tape layer arranged on the first cord tape layer is formed to have a reinforcing fabric embedded in rubber in parallel. The third cord tape layer arranged on the second cord tape layer is formed to have a reinforcing fabric embedded in the rubber in parallel and the fourth cord tape layer arranged on the third cord tape layer is formed to have the rubber embedded in parallel The reinforced fabric...
