Abstract

The invention relates to a pneumatic vehicle tyre with tread profiling which has blocks, these blocks having fine indents (segments) in a wave shape. So that the effect of the fine indents can be matched to the cross-section of the blocks, according to the invention the amplitude of the waves is greater in the centre of the blocks in comparison with the amplitude in the edge area of the blocks. It is expedient in this arrangement that the amplitude of the fine indents becomes gradually greater towards the centre of the blocks.

Description

Die Erfindung betrifft einen Fahrzeugluftreifen mit einer Blöcke auf­ weisenden Laufflächenprofilierung, wobei diese Blöcke Feineinschnitte in Wellenform aufweisen.The invention relates to a pneumatic vehicle tire with a block Pointing tread pattern, these blocks fine cuts have in wave form.

Feineinschnitte sind durch Bleche in der Vulkanisierform erzeugte schmale, langgestreckte Einschnitte, die z.B. eine Breite von 0,5 mm haben und sich im Regelfalle bis in die Wurzel der zugehörigen Blöcke radial nach innen erstrecken. Diese Feineinschnitte führen nicht nur zu einer Verbesserung der Rutschfestigkeit des Reifens, vielmehr sind diese Feineinschnitte auch in der Lage, die Verformbarkeit des zuge­ hörigen Blockes zu beeinflussen.Fine cuts are made by sheets in the vulcanizing mold narrow, elongated incisions, e.g. a width of 0.5 mm have and as a rule down to the root of the associated blocks extend radially inward. These fine cuts not only lead to improve the skid resistance of the tire, rather these fine cuts also capable of deforming the block.

Es ist bekannt, die Feineinschnitte wellenförmig oder zickzackförmig auszubilden, um so eine gewisse Richtungsunabhängigkeit in bezug auf das Greifvermögen der durch die Feineinschnitte bewirkten Kanten zu gewährleisten.It is known that the fine incisions are wavy or zigzag train so as to have a certain directional independence with regard to the grip of the edges caused by the fine incisions guarantee.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, durch eine besondere Formgebung der Feineinschnitte deren Wirkung an den Block­ querschnitt anzupassen.The invention is based on the object by a special shape of the fine cuts their effect on the block adapt cross-section.

Zur Lösung dieser Aufgabe ist erfindungsgemäß die Amplitude der Wellen im Zentrum der Blöcke größer im Vergleich zur Amplitude im Randbereich der Blöcke, wobei vorzugsweise eine allmählich größer werdende Ampli­ tude vom freien Rand der Blöcke zum Blockzentrum hin gewählt wird. Demgemäß wird im Zentrum der Blöcke gewissermaßen eine vergleichsweise große Länge der Feineinschnitte untergebracht, die mit einer erhöhten Verformbarkeit der Blöcke verbunden ist, so daß demgemäß die Blöcke auch im Zentrum ihres Grundrisses eine vergleichsweise große Verform­ barkeit haben, zudem aber auch in diesem Bereich über entsprechend große Maßnahmen zur Erhöhung der Rutschsicherheit verfügen.According to the invention, the amplitude of the waves is used to achieve this object larger in the center of the blocks compared to the amplitude in the edge area of the blocks, preferably a gradually increasing ampli tude is chosen from the free edge of the blocks to the block center. Accordingly, a kind of comparative becomes in the center of the blocks large length of the fine incisions housed with an increased Deformability of the blocks is connected, so that the blocks  a comparatively large deformation also in the center of their floor plan availability, but also in this area via accordingly have large measures to increase slip resistance.

Eine solche Anordnung der Feineinschnitte führt zu einer wesentlichen Verbesserung der Griffigkeit des Reifens sowohl auf nasser Fahrbahn als auch bei verschneitem Untergrund.Such an arrangement of the fine incisions leads to an essential one Improve the grip of the tire both on wet roads as well as on snow-covered ground.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.

Die Abb. zeigt eine Teildraufsicht auf die Lauffläche eines Fahrzeugluftreifens, der vorwiegend für die Winter­ verwendung gedacht ist.The figure shows a partial top view of the tread of a pneumatic vehicle tire, which is primarily intended for winter use.

Zu beiden Seiten der Laufflächenmitte befindet sich eine Blockreihe 1 aus zickzackförmig verlaufenden Blöcken 2. Die Laufflächenränder werden hingegen gebildet von Blockreihen, deren Blöcke 3 von einem im wesentlichen rechteckigen Grundriß sind, und zwar so, daß sie sich im wesentlichen quer zur Reifenumfangsrichtung erstrecken. Die Blöcke 2 und 3 weisen je Feineinschnitte auf mit einer Breite von etwa 0,5 bis 0,8 mm. Die in den Reihen 1 befindlichen Feineinschnitte sind mit 4 und die seitlich außen gelegenen Feineinschnitte mit 5 bezeichnet.On both sides of the center of the tread there is a row of blocks 1 made of blocks 2 running in a zigzag shape. The tread edges, on the other hand, are formed by rows of blocks, the blocks 3 of which are of a substantially rectangular outline, in such a way that they extend essentially transversely to the tire circumferential direction. Blocks 2 and 3 each have fine incisions with a width of approximately 0.5 to 0.8 mm. The fine incisions located in rows 1 are designated by 4 and the fine incisions located on the outside by 5 .

Die Feineinschnitte 4, 5 sind je wellenförmig ausgeführt, jedoch mit der Besonderheit aufgrund der Erfindung, daß die von ihnen beschrie­ bene Amplitude zum Zentrum des Blockes hin größer wird, was bei lang­ gestreckten Blöcken bedeutet, daß die Amplitude auf halber Länge der Blöcke am größten ist. Die Feineinschnitte 5 sind paarweise angeord­ net, während die Feineinschnitte 4 nur in Einzelanordnung vorgesehen sind in der Weise, daß sie von einem freien Rand eines Blockes sich zum anderen freien Rand erstrecken, während die seitlich vorgesehenen Feineinschnitte 5 etwa auf halber Länge der zugehörigen Blöcke enden.The fine incisions 4 , 5 are each wave-shaped, but with the special feature of the invention that the amplitude described by them becomes larger towards the center of the block, which means with elongated blocks that the amplitude is greatest at half the length of the blocks is. The fine incisions 5 are net angeord pairs, while the fine incisions 4 are provided only in a single arrangement in such a way that they extend from one free edge of a block to the other free edge, while the lateral incisions 5 end approximately half the length of the associated blocks .

Es liegt auch im Rahmen der Erfindung, nicht nur eine Änderung der Amplitude vorzunehmen, vielmehr kann auch gleichzeitig die Wellenlänge im Sinne der Vergrößerung der Amplitude verringert werden.It is also within the scope of the invention, not just a change in To make amplitude, rather the wavelength can be simultaneously be reduced in the sense of increasing the amplitude.
