Problems solved by technology

However, a high cord density in two closely arranged working layers leads to higher tensions in the tire in the region of the end cords, which, without additional measures, can lead to loosening of the cord edges and thus disadvantageously significantly affect the durability of cord belts and vehicle tires

Embodiment Construction

[0057] figure 1 and figure 2 A radially constructed pneumatic commercial vehicle tire is shown having two side walls 2 extending in the radial direction R of the pneumatic vehicle tire and a crown region 3 formed axially therebetween. At the ends of their radially inward extension, the side walls are each formed with a bead region 1 in which a movement-proof (zugfester) in the circumferential direction U is formed in the circumferential direction over the entire circumference of the tire. Extended bead core 4 of known type. The bead core 4 is formed in a known manner from a coil of wire embedded in rubber extending in the circumferential direction U of the vehicle pneumatic tire. On the bead core 4 , a horn (core shoe) 6 with a triangular cross-section is formed in a conventional manner from hard rubber material. The vehicle pneumatic tire is formed with a carcass 5 passing outwardly in the radial direction R of the vehicle pneumatic tire from the bead core 4 formed in the...

Abstract

Pneumatic vehicle tyre for commercial vehicles, with a carcass (5), with a breaker belt (9) and with a profiled tread rubber (10), wherein the breaker belt (9) is formed by a number of belt plies (13, 14, 15), which are arranged lying one on top of the other from the radial inside to the radial outside and of which two belt plies (13, 15) are formed as working plies, wherein the radially inner working ply (13) and the radially outer working ply (15) have steel reinforcing elements (23, 25), which are arranged in relation to the circumferential direction at an angle of 10°-24°, wherein the reinforcing elements of the two working plies cross one another, characterized in that the adjacent reinforcing elements (23) of the radially inner ply (13) of the two working plies (13, 15) in the vehicle tyre have different cord spacings in relation to one another than the adjacent reinforcing elements (25) of the radially outer ply (15) of the two working plies (13, 15).

Description

technical field [0001] The present invention relates to a vehicle pneumatic tire for a commercial vehicle having a carcass, having a cord band mounted radially outside the carcass, and having a cord band mounted on the cord band A shaped tread radially outer in which the cord band is formed of a plurality of cord band plies arranged one above the other from the radially inner towards the radially outer, at least two of the cord bands being formed as working layer, where the radially inner and radially outer working layers of the two working layers are layers with parallel steel reinforcing fabric cord belts embedded in rubber, where the reinforcing fabric of the radially inner working layer is in It is oriented at an angle α with the circumferential direction U, with 10°≤α≤24°, and the reinforcing fabric of the radially outer working layer is at an angle γ with the circumferential direction U, with 10°≤γ≤24°, where Seen in the circumferential direction U of the vehicle tire, ...
