Abstract

The invention takes as its departure point a pneumatic vehicle tyre, whose profiled tread exhibits a wear indicator. In order to permit a relatively accurate judgement of the degree of wear of the tread, the invention provides, in the tread, an incision whose side surface forms a comparatively small angle, of approximately 30 to 60 DEG , but preferably of approximately 40 DEG , with respect to the tread. Consequently, the indicating surface of the indicator incision is enlarged.

Description

Die Erfindung betrifft einen Fahrzeugluftreifen mit einem profilier­ ten Laufstreifen, der mit einem Abnutzungsindikator versehen ist.The invention relates to a pneumatic vehicle tire with a profiling tread, which is provided with a wear indicator.

Abnutzungsindikatoren haben die Aufgabe, dem Benutzer des Fahrzeugs den Abnutzungszustand seines Luftreifens anzuzeigen. Die bekannten Indikatoren dieser Art haben aber den Nachteil, daß sie nur den gesetzlich vorgeschriebenen Endzustand aufzeigen. Wenn dieser Zustand erreicht bzw. der Laufstreifen abgefahren ist, kann eine weitere Benutzung des Luftreifens nicht mehr stattfinden.Wear indicators are responsible for the user of the vehicle indicate the state of wear of its tire. The well-known However, indicators of this type have the disadvantage that they only Show the legally required final state. If this condition reached or the tread is worn, another Use of the tire no longer take place.

Aufgrund der Erfindung soll ein Fahrzeugluftreifen vorgeschlagen werden, dessen Abnutzungsindikator eine relativ genaue Beurteilung des Abnutzungsgrades des Reifenlaufstreifens ermöglicht. Es soll also auch dann schon eine Beurteilung möglich sein, wenn der Lauf­ streifen erst geringfügig, also beispielsweise nur zu einem geringen Teil abgefahren ist.A pneumatic vehicle tire is proposed on the basis of the invention the wear indicator is a relatively accurate assessment the degree of wear of the tire tread. It should So an assessment should be possible even when the run streak only slightly, for example only to a small extent Part has left.

Zur Lösung dieser Aufgabe ist erfindungsgemäß im Laufstreifen ein Einschnitt vorgesehen, dessen Seitenfläche in bezug auf die Lauf­ fläche einen vergleichsweise kleinen Winkel, und zwar einen Winkel von nur etwa 30 bis 60°, vorzugsweise einen Winkel von etwa 40° bildet.To solve this problem, the tread according to the invention Incision provided, the side surface with respect to the barrel area a comparatively small angle, namely an angle from only about 30 to 60 °, preferably an angle of about 40 ° forms.

Dieser geringe Anstieg führt zu einer vergleichsweise großen Anzeige­ fläche des Indikatoreinschnittes, so daß sehr gut der Abnutzungs­ zustand des Laufstreifens beurteilt werden kann. Eine solche Beur­ teilung kann dann noch erleichtert vollzogen werden, wenn die flach ansteigende Seitenfläche der Einschnitte mit Kennzeichnungen, ggf. mit Zahlen versehen ist.This slight increase leads to a comparatively large display area of the indicator incision, so that the wear is very good condition of the tread can be assessed. Such an appraisal division can then be made even easier if the flat  increasing side surface of the incisions with markings, if necessary with Numbers is provided.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt:In the drawing, an embodiment of the invention is shown. It shows:

Fig. 1 einen radialen Teilschnitt durch einen Fahrzeugluft­ reifen und Fig. 1 ripen a radial partial section through a vehicle air and

Fig. 2 eine Draufsicht auf den Laufflächenabschnitt gemäß Fig. 1. FIG. 2 shows a top view of the tread section according to FIG. 1.

Die die Profilierung des Laufstreifens 1 bildenden Blöcke 2 sind durch Nuten 3 voneinander getrennt. Von diesen gehen Einschnitte 4 zur Seite hin aus. Diese Einschnitte 4 haben eine Breite, die geringer ist als diejenige der Nuten 3.The blocks 2 forming the profile of the tread 1 are separated from one another by grooves 3 . Notches 4 extend from these to the side. These cuts 4 have a width that is less than that of the grooves 3 .

Wichtig ist, daß die Seitenflächen 5, also der Grund wesentlich flacher ansteigen als die Seitenflächen 6 der Nut 3. Der Anstieg der Seiten­ flächen 5 beträgt - gemessen gegenüber der Lauffläche 7 - lediglich etwa 40°.It is important that the side faces 5 , that is to say the bottom, rise substantially flatter than the side faces 6 of the groove 3 . The increase in the side surfaces 5 is - measured compared to the tread 7 - only about 40 °.

Die Seitenflächen 5 können mit beliebigen Markierungen ausgestattet sein, die die Ablesung erleichtern.The side surfaces 5 can be equipped with any markings that facilitate reading.
