Embodiment Construction

[0027] The present invention seeks to achieve a specific configuration of circumferential grooves in the tread of a vehicle pneumatic tire for passenger motor vehicles or trucks to reduce tire noise / road noise, especially through these circumferential grooves when the tire is rolling Or that part of the noise generated in these circumferential grooves. The generation and propagation of sound waves in the circumferential grooves is in particular due to the so-called "horn" effect, in which all sound waves are amplified by forming a sound funnel between the curved tire rolling surface and the road when the tire is turned in and out. The sound of firing. Furthermore, during rolling, the circumferential grooves form tubular resonators with the road surface, wherein a noise fraction in this tire noise / road noise can be generated by flow processes and the periodic interaction of these resonances.

Abstract

The invention discloses a pneumatic vehicle tyre. The pneumatic vehicle tyre for passenger vehicles or vans has at least one wide circumferential groove (1, 1', 1", 1"'), which runs in the circumferential direction and is bounded on the tread periphery by two edge borders (1a, 1'a, 1" a, 1"'a) which run parallel to one another and linearly, and has a groove base (13, 13', 13") as well as two groove edges (9, 10, 9', 10', 9", 10"), wherein elements (11, 12, 11' 12', 11", 12") which project on the groove edges (9, 10, 9', 10', 9", 10") are formed alternately in the circumferential direction on one or other of the groove edges (9, 10, 9', 10', 9", 10"), wherein each projecting element (11, 12, 11', 12', 11", 12") has a groove edge section (9a, 10a, 9'a, 10'a, 9"a, 10"a) lying opposite on the opposite groove edge (9, 10, 9', 10', 9", 10"), which groove edge section (9a, 10a, 9'a, 10'a, 9"a, 10"a) runs least essentially in the radial direction starting at the edge border (1a, 1'a, 1"a, 1"'a) as far as the groove base (13, 13', 13"), wherein the groove base (13, 13', 13") runs in a meandering or corrugated shape along and between the projecting elements (11, 12, 11', 12', 11", 12"), wherein the projecting elements (11, 12, 11', 12', 11", 12") are essentially of wedge-like design and are bounded by oblique faces (14, 14', 14") which extend in the axial direction as far as the groove base (13, 13', 13") and run in the circumferential direction at least essentially over the circumferential extent of the elements (11, 12, 11', 12', 11", 12"), wherein the projecting elements (11, 12; 11',12',11",12") are provided in at least two different circumferential lengths (L1 to L5, L1' to L5'; L1" to L5") and follow one another according to a specific sequence over the circumference of the circumferential groove (1, 1', 1", 1"' ).

Description

technical field [0001] The present invention relates to a vehicle pneumatic tire for passenger motor vehicles or trucks, the vehicle pneumatic tire having at least one wide circumferential groove running in the circumferential direction, which is formed at the periphery of the tread by two The parallel and rectilinear edges delimit and have a groove base and two groove sides, wherein the protruding elements on the groove sides are formed alternately in the circumferential direction on the one and the other groove side, wherein , each protruding element is opposite a groove side section at the opposite groove side, the groove side section runs at least substantially in the radial direction and starts at the edge up to the groove bottom , wherein the grooved base runs meandering or undulating along the protruding elements and between the protruding elements. Background technique [0002] A pneumatic vehicle tire of this type, preferably a commercial vehicle tire, is known fro...
