Embodiment Construction

[0063] Figure 1 to Figure 4 A tread pattern of a prior art vehicle pneumatic tire for passenger cars is shown. The vehicle pneumatic tire is constructed in a known manner (not shown in detail) and has: two tire beads extending in the circumferential direction U on the circumference of the vehicle pneumatic tire; A carcass of radial construction extending upward and in the axial direction A of a pneumatic tire of a vehicle from bead to bead, the carcass having one or two layers of reinforcing fabric embedded in rubber; A buffer extending in the radial direction R of the vehicle pneumatic tire outside the carcass, in the circumferential direction U on the circumference of the vehicle pneumatic tire, and in the axial direction A of the vehicle pneumatic tire from shoulder to shoulder Belt with one or two layers of reinforcing fabric made of steel or aramid embedded in rubber; A strip with a reinforcing fabric oriented in the circumferential direction embedded in rubber so as t...

Abstract

The invention relates to a tread profile of a pneumatic tire for vehicles having radially raised profile elements (1, 2, 3, 4) - in particular profile block elements and/or profile ribs - separated from each other by profile grooves (13, 14, 15), wherein at least one profile groove (14) is formed having a directional component of the main extent thereof in the circumferential direction U of the pneumatic tire for vehicles, wherein the profile groove (14) is formed having a groove root (18) aligned along the extent thereof and having a groove wall (16, 17) on each side of the groove root (18), formed having a groove wall (16, 17) extending in the radial direction R thereof from the groove root (18) to the shell surface radially outwardly delimiting the adjacent profile elements (2, 3), wherein a plurality of protrusions (20); is formed in the groove root distributed along the main extent of the groove (14), wherein said protrusions (20) each are made of at least two protrusion segment disposed adjacent to each other in the direction transverse to the main extent of the groove (14), wherein the protrusion (20) forms the shell surface of a cylindrical segment or a truncated cone segment in one of the two adjacent protrusion segments, and the shell surface of a cylindrical segment or a truncated cone segment in the other, wherein the axes of the cylinder segment or truncated cone segment are formed below the groove (14) having main direction components transverse to the main extent direction of the groove, wherein the two adjacent protrusion segments are formed having different radii of curvature over the extent of each in the protrusion segment.

Description

technical field [0001] The invention relates to a tire stripe of a pneumatic tire for a vehicle, the tire stripe has a plurality of radially raised stripe units separated from each other by a plurality of stripe grooves, especially a stripe block unit and / or a stripe rib, wherein at least A striated groove whose main extension has a directional component in the circumferential direction of a pneumatic tire for vehicles, wherein said striated groove is configured with a groove base oriented along its extension and on both sides of said groove base In each case a groove wall is formed, which extends in its radial direction from the groove base to radially outward and delimits the outer surface of the adjacent strip unit. Background technique [0002] The human ear is extremely sensitive to noise in the frequency range of 1000 Hz. In operation, a vehicle pneumatic tire happens to exhibit disturbing resonances in this range. [0003] Such tire stripes are well known. The circ...
