Problems solved by technology

However, these linear projections and thus the shadow-type pattern may therefore be particularly sensitive to friction during tire sidewall contact with ground stones or also during the transport of the tire, thus reducing the depth of the raised lines and the shadow-type pattern produced. pattern lifespan
Furthermore, these completely straight, linear raised surface profile sections that intersect at acute angles create contamination problems in the side shells formed in the tire curing mold for forming the side walls, which make it possible to additionally create Exhaust problems in the process

Embodiment Construction

[0027] figure 1By way of example, a construction of a pneumatic vehicle tire for passenger cars mounted on a rim 17 is shown, in which a bead core 6 (not shown) with a core profile is surrounded by a bead core 6 consisting of one or more layers. The carcass 4 of radial construction is surrounded in a conventionally known manner by carcass layers arranged one above the other starting from the bead core 6 between an inner layer of a known type formed particularly airtight extends inwardly through the shoulder area shown on the right (equatorial plane of the vehicle's pneumatic tire ), the shoulder area on the left (not shown) and up to the bead core with the core profile on the left (not shown), so that it is surrounded in a conventional manner.

[0028] For simplicity, in figure 1 Only the construction half on its right side is shown in Pneumatic tires for vehicles in , the construction halves go all the way to the equatorial plane These carcass plies consist in a conv...

Abstract

Vehicle tyre - in particular pneumatic vehicle tyre - with a profiled tread (2) and two side walls (1), wherein a hatched pattern composed of multiple linear protrusions (13) is formed on at least one side wall (1), which protrusions (13) can be assigned to a set of curves (9, 10, 11, 12) and do not intersect within the surface region (8) of the side wall (1) which is formed with the hatched pattern, wherein the linear protrusions (13) are each formed along their extent with an extent height of h < 0.8 mm measured perpendicularly with respect to the lateral surface contour of the side wall (1), wherein the linear protrusions (13) are each formed with a sectional contour in the cross-sectional planes perpendicular to the main direction of extent of the linear protrusion (13), which sectional contour is formed with a contour profile which is curved towards the interior of the tyre, at least in the outer part of the extent which is formed between the extent height (h / 2) and the extent height h of the linear protrusion (13) and which is formed in such a way that it points away from the tyre, and said sectional contour being formed with an apex point S of the protrusion (13) which is formed in the extent height h.

Description

technical field [0001] The present invention relates to a vehicle tire having a profiled tread and two sidewalls, in particular a pneumatic tire for vehicles, in which a pattern of shadowed (schraffurartiges) consisting of a plurality of linear protrusions is formed on at least one of the sidewalls , the linear projections are assigned to a curve family (Kurvenschar) and the linear projections do not intersect within the surface area of ​​the side walls formed with a hatched pattern, wherein the linear projections are each formed with a The extension height h, measured perpendicular to the outer contour of the side wall, is ≤ 0.8 mm. Background technique [0002] Pneumatic tires for such vehicles have long been known. This design with such shaded linear projections is used in the surface area of ​​the tire sidewall formed around the lettering displayed on the sidewall. This type of shaded design is also used in tire designs in which letters shown in capitals are formed on ...
