Embodiment Construction

[0025] figure 1 and figure 2 Shown is a pneumatic tire of radial configuration for a utility vehicle having two side walls 2 extending in the radial direction R of the vehicle tire and having axially formed between said side walls The crown area (top area)3. These side walls each have, on their extended ends directed inwards in the radial direction, a bead area 1 in which a bead core 4 of known type is formed, which in the circumferential direction U Has high tensile strength and extends circumferentially over the circumference of the tire. In a known manner, the bead core 4 is formed in a wound manner from a wire, which extends in the circumferential direction U of the pneumatic vehicle tire and is embedded in rubber. An apex (bead filler) 6 that is triangular in cross section is formed on the bead core 4 from a hard rubber material in a conventional manner. The pneumatic vehicle tire is formed with a carcass 5 extending outward across the left-hand side in the radial d...

Abstract

Vehicle pneumatic tyre for utility vehicles having a carcass (5), having a belt (9) which is built up radially outside the carcass (5) and having a profiled tread (10) which is built up on the belt (9), radially outside the belt (9), wherein the belt (9) is formed from at least four belt layers (14, 17, 13, 15) arranged lying one on the other from radially on the inside to radially on the outside, wherein the first belt layer (14) which is arranged furthest on the inside in the radial direction R is embodied with parallel strength members (24) embedded in rubber, the second belt layer (17) which is arranged on the first belt layer (14) is embodied with parallel strength members (27) embedded in rubber, the third belt layer (13) arranged on the second belt layer (17) is embodied with parallel strength members (23) embedded in rubber, and the fourth belt layer (15) arranged on the third belt layer (13) is embodied with parallel strength members (25) embedded in rubber, characterized in that the third belt layer (13) and the fourth belt layer (15) are working layers in which the strength members (23) of the third belt layer (13) enclose in their orientation an angle alpha with respect to the circumferential direction U where 10 degrees < alpha < 45 degrees and the strength members (25) of the fourth belt layer (15) enclose in their orientation in each case an angle gamma with respect to the circumferential direction U where 10 degrees <= gamma <= 45 degrees, wherein, when viewed in the circumferential direction U of the vehicle tyre, the strength members (23) of the third belt layer (13) have an opposed axial direction of inclination to that of the strength members (25) of the fourth belt layer (15), in that the strength members (24) of the first belt layer (14) enclose in their orientation an angle beta with respect to the circumferential direction U where 0 degrees <= beta <= 5 degrees, and the strength members (27) of the second belt layer (17) enclose in their orientation an angle epsilon with respect to the circumferential direction U where 40 degrees <= epsilon <= 75 degrees.

Description

technical field [0001] The present invention relates to a pneumatic vehicle tire for a utility vehicle, the pneumatic vehicle tire having a carcass, having a belt constructed on the outside in the radial direction of the carcass, and having a belt constructed on the belt A shaped tread radially outer, wherein the belt is formed of at least four belt layers arranged on top of each other from radially inner to radially outer, wherein in the radial direction R The first belt layer arranged on the innermost side is formed with a plurality of parallel strength members embedded in rubber, and the second belt layer arranged on the first belt layer is formed with a plurality of parallel strength members embedded in rubber. strength members, a third belt layer arranged on the second belt layer is formed with parallel strength members embedded in rubber, and a fourth belt layer arranged on the third belt layer forms There are multiple parallel strength members embedded in the rubber. ...
