Fahrzeugluftreifen Vehicle tires
Die Erfindung betrifft einen Fahrzeugluftreifen mit einem Laufstreifen mit in mehreren Spikespuren angeordneten Spikes, wobei das mittlere Drittel der Aufstandsfläche des Laufstreifens frei von Spikes bleibt. The invention relates to a pneumatic vehicle tire with a tread with arranged in several spikes tracks spikes, the middle third of the footprint of the tread remains free of spikes.
Die Ice-Performance eines mit einem bespikten Laufstreifen versehenen Reifens wird im Wesentlichen durch die Anzahl der Spikes, das Spikegewicht, den Überstand der The ice performance of a bespikts treaded tire is essentially determined by the number of spikes, the spike weight, the supernatant of
Spikepins über die Laufstreifenoberfläche sowie die Position der Spikes im Laufstreifen bestimmt. Da die Anzahl der Spikes im Laufstreifen, das Gewicht der Spikes, deren Überstand über die Laufstreifenperipherie durch gesetzliche Vorschriften limitiert bzw. vorgegeben sind steht als Optimierungsparameter im Wesentlichen die Spikepositionierung zur Verfügung. Es ist üblich, Spikes über den Reifenumfang in Spikespuren - entlang von parallel zum Reifenäquator in Umfangsrichtung kreisförmigen umlaufenden Linien - anzuordnen. Um den Effekt der Spikes auf eisigem Untergrund voll zu erhalten ist es üblich die Spikes in einer Anzahl von Spuren, insbesondere zwischen acht und vierzehn Spuren, anzuordnen, um zu verhindern, dass beim Abrollen des Reifens ein in den Spike pins over the tread surface as well as the position of the spikes in the tread determined. Since the number of spikes in the tread, the weight of the spikes, whose protrusion over the tread periphery are limited or prescribed by law, the optimization parameter is essentially spike positioning. It is common to arrange spikes over the circumference of the tire in spiked tracks - along circumferential circumferential lines parallel to the tire equator. In order to keep the effect of the spikes on icy ground full it is common to arrange the spikes in a number of tracks, especially between eight and fourteen tracks, to prevent when rolling the tire into the
Untergrund eintretender Spike in eine bereits vorhandene Kratzspur im Eis, welche ein vorher in den Untergrund eingetretener Spike verursacht hat, eintritt. Für das Underground entering spike enters an existing scratch track in the ice, which has caused a previously entered into the underground spike occurs. For the
Abrollgeräusch von mit Spikes versehenen Laufstreifen ist es jedoch vorteilhafter, möglichst wenige Spikespuren vorzusehen. Darüber hinaus ist die Wirkung von Spikes in den der Laufstreifenmitte benachbarte Spikespuren etwas höher, was dazu führt, dass möglichst viele Spuren soweit wie möglich nahe dem Reifenmittelbereich angeordnet werden. Diese Randbedingungen führen dazu, dass die Spikes in den einzelnen However, rolling noise of treads provided with spikes, it is more advantageous to provide as few spikes traces. In addition, the effect of spikes is slightly higher in the tread marks adjacent the tread center, resulting in as many tracks as possible being located as close as possible to the tire mid-area. These boundary conditions cause the spikes in the individual
Spikespuren unter geringeren Abständen angeordnet werden. Auch bei mit ABS ausgerüsteten Fahrzeugen hat sich nun herausgestellt, dass es beim Bremsen immer wieder vorkommt, dass innerhalb einer Spikespur angeordnete Spikes in die Kratzspur von vorherigen Spikes, wie oben geschildert, eintreten und dadurch die Wirkung der Spikes beeinträchtigt wird. Der Erfindung liegt die Aufgabe zugrunde, an Laufstreifen von Reifen, vorzugsweise solchen, die auf Fahrzeugen mit ABS verwendet werden, die Spikes in den Spikespuren derart anzuordnen, dass beim Bremsen ein Eintauchen von Spikes in die Kratzspur eines vorherigen Spikes vermieden ist. Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass die Maximalanzahl der Spikes pro Spikespur der aus der Gleichung U / 125 ermittelten ganzen Zahl entspricht, wobei U der entlang des Reifenäquators gemessene Umfang des neuen Reifens in mm ist, und wobei der Mindestabstand der Spikes innerhalb einer Spikespur 125mm beträgt. Durch die erfindungsgemäße Anordnung der Spikes in den Spikespuren wird verhindert, dass ein in den Untergrund einlaufender Spike in eine unter der Wirkung des ABS -Systems durch einen vorherigen Spike erzeugte Kratzspur im Eis eintaucht. Die Wirkung der Spikes auf Eis bleibt somit voll erhalten. Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die ein Ausführungsbeispiel darstellt, näher beschrieben. Dabei zeigt die einzige Figur, Fig. 1, eine Draufsicht auf eine Teilabwicklung eines Laufstreifens eines Fahrzeugluftreifens. Der in der Figur gezeigte Laufstreifen ist für Winterreifen von Personenkraftwagen vorgesehen und ist mit Spikes 1 versehen. Die in der Figur dargestellte Ausgestaltung des Laufstreifens mit Profilelementen ist für die Erfindung nicht von Belang, sodass auf sie nur kurz eingegangen wird. Der Laufstreifen weist schulterseitig je eine Blockreihe 2, 2' mit durch Quernuten 3, 3' voneinander getrennten Blöcken 2a, 2'a auf, wobei der Blockreihe 2 benachbart jeweils paarweise angeordnete und in Umfangsrichtung durch Schrägrillen 4 voneinander getrennte Blöcke 4, 5 und der Schulterblockreihe 2' benachbart eine weitere Blockreihe 6 aus durch Quernuten 9 voneinander getrennten Blöcken 6' verlaufen. Über den Laufstreifenumfang zick-zack- förmig verlaufende Nuten 7, 7' trennen die Blockreihe 6 von den Blöcken 5 und von den Schulterblöcken 2'a. Die Mittelumfangslinie des Laufstreifens bzw. die Äquatorlinie des Reifens ist mit A-A, die Aufstandsflächenbreite des Laufstreifens bei am Fahrzeug montiertem Reifen ist mit B bezeichnet. Die Spike traces are arranged at shorter intervals. Even with vehicles equipped with ABS, it has now been proven that when braking again and again occurs that located within a spike track spikes in the scratch track of previous spikes, as described above, occur and thereby the effect of the spikes is impaired. The invention is based on the object of treads of tires, preferably those that are used on vehicles with ABS, the spikes in the spike tracks to be arranged such that when braking an immersion of spikes in the scratch track of a previous spike is avoided. The object is achieved according to the invention in that the maximum number of spikes per track matches the determined from the equation U / 125 integer, where U is measured along the tire equator circumference of the new tire in mm, and wherein the minimum distance of the spikes within a Spike track is 125mm. The inventive arrangement of the spikes in the spike lanes prevents a running into the ground spike is immersed in a generated under the action of the ABS system by a previous spike scratch track in the ice. The effect of the spikes on ice thus remains fully intact. Further features, advantages and details of the invention will now be described with reference to the drawing, which illustrates an embodiment in more detail. The sole FIGURE, Fig. 1, shows a plan view of a partial development of a tread of a pneumatic vehicle tire. The tread shown in the figure is intended for winter tires of passenger cars and is provided with spikes 1. The embodiment of the tread with profile elements shown in the figure is not relevant to the invention, so they will be discussed only briefly. The tread on the shoulder side each have a row of blocks 2, 2 'with mutually separated by transverse grooves 3, 3' blocks 2a, 2'a, wherein the block row 2 adjacent each paired and circumferentially by oblique grooves 4 separate blocks 4, 5 and the Shoulder block row 2 'adjacent another Block row 6 from 6 separated by transverse grooves 9 blocks' run. About the tread circumference zigzag-shaped extending grooves 7, 7 'separate the block row 6 of the blocks 5 and the shoulder blocks 2'a. The center circumference line of the tread or the equatorial line of the tire is designated by AA, the tread width of the tread in the case of a tire mounted on the vehicle is denoted by B. The
Profilblöcke 2a, 2'a, 4, 5 und 6' sind jeweils mit einer Vielzahl von Einschnitten 8 mit einer Breite von 0,4 mm bis 0,6 mm versehen. In jedem Profilblock 2a, 2'a, 4, 5 und 6' verlaufen die Einschnitte 8 jeweils zumindest im Wesentlichen parallel zueinander und, wie gezeigt, im Wesentlichen in oder unter einem spitzen Winkel zur  Profile blocks 2a, 2'a, 4, 5 and 6 'are each provided with a plurality of sipes 8 having a width of 0.4 mm to 0.6 mm. In each profile block 2a, 2'a, 4, 5 and 6 ', the incisions 8 each extend at least substantially parallel to each other and, as shown, substantially at or at an acute angle to
Laufstreifenquerrichtung. Die Einschnitte 8 können in Draufsicht betrachtet und wie gezeigt zumindest abschnittsweise einen wellen-, zick-zack- oder treppenförmigen Verlauf aufweisen. Tread transverse direction. The incisions 8 can be viewed in plan view and, as shown, at least in sections have a wave, zig-zag or staircase-shaped course.
Im Zentralbereich Z des Laufstreifens, welcher sich über ein Drittel der In the central area Z of the tread, which is about one third of the
Aufstandsflächenbreite B erstreckt, ist der Laufstreifen frei von Spikes, gemäß den gesetzlichen Anforderungen für mit Spikes versehenen Winterreifen. In den beiden Seitenbereichen Sl und S2 sind die Spikes 1 in Spikespuren Si bis s10 angeordnet, wobei die Spikespuren Si bis s5 in der einen und die Spikespuren s6 bis s10 in der zweiten Footprint width B extends, the tread is free of spikes, in accordance with the legal requirements for spiked winter tires. In the two side areas Sl and S2, the spikes 1 are arranged in spike tracks Si to s 10 , the spike tracks Si to s 5 in one and the spike tracks s 6 to s 10 in the second
Laufstreifenhälfte und zur Äquatorlinie A-A symmetrisch verlaufend angeordnet sind. Unter einer Spikespur wird eine in Umfangsrichtung des Laufstreifens bzw. Reifens kreisförmig umlaufende Linie verstanden, auf welcher jeweils eine Anzahl von Spikes 1, wie noch beschrieben wird, positioniert ist. Tread half and equatorial line A-A are arranged to extend symmetrically. A spike track is understood to mean a circular circumferential line in the circumferential direction of the tread or tire, on each of which a number of spikes 1, as will be described, are positioned.
Gemäß der Erfindung beträgt die maximale Anzahl der Spikes 1 in einer Spur Si bis s10 der aus der Division des in mm angegebenen Umfangs U des Reifens durch die Zahl 125, ermittelbaren ganzen Zahl, die Kommastellen bleiben unberücksichtigt. Der According to the invention, the maximum number of spikes 1 in a track Si to s 10 is the integer number that can be determined from the division of the circumference U of the tire indicated in mm, the decimal places are disregarded. Of the
Minimalabstand der Spikes 1 in einer Spikespur Si bis s10 beträgt 125mm. Über den Umfang des Laufstreifens können die Spikes 1 in den Spikespuren Si bis s10 unter gleichen oder im Wesentlichen gleichen Abständen angeordnet sein, insbesondere dann, wenn ihre Anzahl der Maximalanzahl entspricht. Der Umfang U des Reifens wird bei neuem Reifen und entlang des Reifenäquators A-A ermittelt. Die Zahl 125 basiert auf der durchschnittlichen Schlupflänge von etwa 125 mm, welche beim ersten Schlupfereignis beim Blockierbremsen eines Fahrzeuges, welches mit ABS ausgerüstet ist, bei einer Geschwindigkeit von 90 km/h (höchste zulässige Geschwindigkeit bei Spikereifen) auftritt. Beim Fahren auf eisigem Untergrund hinterlassen die Spikes 1 bei einem derartigen Bremsmanöver in der Bodenaufstandsfläche eine Kratzspur bestimmter Länge im Eis. Die durch die Erfindung vorgegebene Maximalanzahl der Spikes 1 und der vorgegebene Mindestabstand eines nachfolgenden Spike 1 in der gleichen Spur verhindert, dass dieser Spike 1 in die Kratzspur des vorherigen Spikes 1 eintaucht. Dadurch bleibt die Wirkung sämtlicher Spikes 1 in allen Spikespuren Si bis s10 voll erhalten. Minimum distance of spikes 1 in a spike track Si to s 10 is 125mm. Over the circumference of the tread, the spikes 1 in the spike tracks Si to s 10 may be arranged at equal or substantially equal intervals, in particular if their number corresponds to the maximum number. The circumference U of the tire is determined on a new tire and along the tire equator AA. The number 125 is based on the 125 mm average slip length which occurs at the first slip event during stalling braking of a vehicle equipped with ABS at a speed of 90 km / h (maximum permissible speed for studded tires). When driving on an icy surface leave the spikes 1 in such a braking maneuver in the ground contact patch a scratch track of certain length in the ice. The predetermined by the invention maximum number of spikes 1 and the predetermined minimum distance of a subsequent spike 1 in the same lane prevents this spike 1 is immersed in the scratch track of the previous spike 1. As a result, the effect of all spikes 1 is fully preserved in all spike lanes Si to s 10 .
Bei einem PKW- Winterreifen der Dimension 205/55R16 mit einem Umfang von For a car winter tire of dimension 205 / 55R16 with a circumference of
2002,8 mm ergibt sich aus U / 125 als Maximalanzahl der Spikes 1 pro Spikespur Si bis s10 16. In den einzelnen Spikespuren sl bis slO können beispielsweise folgende Spikeanzahlen gewählt werden: 2002.8 mm results from U / 125 as the maximum number of spikes 1 per spike track Si to s 10 16.
