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 1 An example of the structure of a pneumatic vehicle tire for a passenger car mounted on a rim 17 is shown, in which a bead core 6 (not shown) with a core profile is surrounded by a diameter composed of one or more layers The structural carcass 4 is surrounded in a conventionally known manner by carcass layers arranged on top of each other, starting from the bead core 6, between an inner layer of a known kind that is formed to be particularly airtight. The inside extends through the shoulder area shown on the right (the equatorial plane of the vehicle’s pneumatic tire ), the shoulder area on the left side (not shown) and up to the bead core with the core profile on the left side (not shown), so that it is enclosed in a conventional manner.

[0028] For simplicity, in figure 1 Only shows the construction half on its right side In the vehicle pneumatic tire, the structure half reaches the equatorial plane These carcass layers are conventionally composed of a known...

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 with a molded tread and two sidewalls, especially a pneumatic vehicle tire, in which a schraffurartiges pattern composed of a plurality of linear protrusions is formed on at least one sidewall These linear protrusions belong to a curvilinear family (Kurvenschar), and these linear protrusions do not intersect within the surface area of ​​the side wall formed as a shadow pattern, wherein the linear protrusions are formed to have a curve along their extension. The extension height measured perpendicular to the outer contour (Mantelkontur) of the side wall h≤0.8mm. Background technique [0002] This type of vehicle pneumatic tire has long been known. This design with such shaded linear protrusions is used in the surface area of ​​the sidewall formed around the letters displayed on the tire sidewall. This kind of shaded design is also used in tire design, in which letters displayed in capitals are formed on the s...
