Abstract
Die Erfindung betrifft einen Fahrzeugluftreifen mit einer Radialkarkasse (2) und zwei Wulstbereichen (1), welche je einen Wulstkern (3) und einen dem Wulstkern (3) aufsitzenden Wulstkernreiter (4) aufweisen, wobei die Karkasse (2) von axial innen nach axial außen um die Wulstkerne (3) geführt ist und in einem Karkasshochschlag (2a) endet und wobei Wulstverstärker (6) in den beiden Wulstbereichen (1) des Fahrzeugluftreifens angeordnet sind, wobei ein Wulstverstärker (6) Monofilamente aus Stahl als Festigkeitsträger aufweist. Die Erfindung zeichnet sich dadurch aus, dass die Monofilamente derart in dem Wulstverstärker angeordnet sind, dass diese einen Winkel α von 48° bis 60 mit der Umfangsrichtung einschließen gerade und linienförmig ausgebildet sind.The invention relates to a pneumatic vehicle tire having a radial carcass (2) and two bead regions (1) each having a bead core (3) and a bead core rider (4) seated on the bead core (3), the carcass (2) extending axially inward to axially externally around the bead cores (3) and ending in a carcass turn-up (2a) and wherein bead reinforcements (6) are arranged in the two bead regions (1) of the pneumatic vehicle tire, a bead reinforcement (6) comprising steel monofilaments as reinforcement. The invention is characterized in that the monofilaments are arranged in the bead reinforcement such that they form an angle α of 48 ° to 60 with the circumferential direction being straight and linear.
Description
Die Erfindung betrifft einen Fahrzeugluftreifen mit einer Radialkarkasse und zwei Wulstbereichen, welche je einen Wulstkern und einen dem Wulstkern aufsitzenden Wulstkernreiter aufweisen, wobei die Karkasse von axial innen nach axial außen um die Wulstkerne geführt ist und in einem Karkasshochschlag endet und wobei Wulstverstärker in den beiden Wulstbereichen des Fahrzeugluftreifens angeordnet sind, wobei der Wulstverstärker Monofilamente aus Stahl als Festigkeitsträger aufweist. The invention relates to a pneumatic vehicle tire having a radial carcass and two bead regions, each having a bead core and a bead apex seated on the bead core, the carcass being guided axially inward to axially outward about the bead cores and terminating in a carcass turnup, and bead reinforcements in the two bead regions the pneumatic vehicle tire are arranged, wherein the bead reinforcement monofilaments made of steel as a strength carrier.
Ein derartiger Fahrzeugluftreifen ist aus der
Aus der
Wulstverstärker sind dem Fachmann hinreichend bekannt. Das obere Ende des Wulstverstärkers, welches dem Gürtel zugewandt ist, kann oberhalb oder unterhalb des oberen Ende des Wulstkernreiters enden und das untere Ende des Wulstverstärkers endet auf Höhe des Wulstkernreiters oder auf Höhe des Wulstkernes. Das obere Ende des Wulstverstärkers reicht nie unter den Gürtel. Der Wulstverstärker ist eine gummierte Festigkeitsträgerlage, welche parallel zueinander und voneinander beanstandete Festigkeitsträger aufweist und welche ringkreisförmig im Bereich des Wulstes um den Reifen umläuft. Bead reinforcements are well known to those skilled in the art. The upper end of the bead enhancer which faces the belt may terminate above or below the upper end of the bead apex and the lower end of the bead enhancer terminates at the level of the bead apex or at the level of the bead core. The upper end of the bead enhancer never reaches under the belt. The bead enhancer is a rubberized reinforcing layer which has mutually parallel reinforcements and mutually opposing reinforcements and which circulates around the hoop in the region of the bead.
Man ist ständig bemüht, das Handling des Fahrzeugluftreifens zu verbessern, ohne seine übrigen Eigenschaften nachteilig zu beeinflussen. It is constantly trying to improve the handling of the pneumatic vehicle tire without adversely affecting its other properties.
Es ist daher die Aufgabe der Erfindung, einen Fahrzeugluftreifen zur Verfügung zu stellen, der ein verbessertes Handling aufweist, ohne dessen Rollwiderstand zu verschlechtern. It is therefore the object of the invention to provide a pneumatic vehicle tire having improved handling without deteriorating its rolling resistance.
Die Aufgabe wird gelöst, indem die Monofilamente derart in dem Wulstverstärker angeordnet sind, dass diese einen Winkel α von 48° bis 60° mit der Umfangsrichtung einschließen. The object is achieved by arranging the monofilaments in the bead reinforcement in such a way that they enclose an angle α of 48 ° to 60 ° with the circumferential direction.
Der Wulstverstärker des erfindungsgemäßen Reifens dient der Versteifung des Wulstbereiches, was durch seine geraden, nicht wellenförmig oder spiralförmig verformten Monofilamente erreicht wird. Ferner bilden die Festigkeitsträger des Wulstverstärkers mit den Festigkeitsträgern der Karkasse mit den vorgenannten Winkeln einen sehr geeigneten Kreuzverband, wodurch die Schubverformungen in der Seitenwand deutlich reduziert werden. Durch beides wird ein Handlingvorteil ohne Nachteil im Rollwiderstand erreicht. Der Wulstverstärker reicht mit seinem dem Gürtel zugewandten Ende nicht bis unter diesen. The bead reinforcement of the tire according to the invention serves to stiffen the bead area, which is achieved by its straight, non-wavy or helically deformed monofilaments. Furthermore, the reinforcing elements of the bead reinforcement with the reinforcements of the carcass with the aforementioned angles form a very suitable cross dressing, whereby the shear deformations in the side wall are significantly reduced. By both a handling advantage without disadvantage in the rolling resistance is achieved. The bead enhancer does not reach below the belt-facing end.
Vorteilhaft ist es, wenn die Monofilamente eine Konstruktion 1 × 0,15 mm bis 1 × 0,35 mm, vorzugsweise die Konstruktion 1 × 0,30 mm aufweisen. It is advantageous if the monofilaments have a construction 1 × 0.15 mm to 1 × 0.35 mm, preferably the construction 1 × 0.30 mm.
Vorteilhaft ist es, wenn die Monofilamente im Wulstverstärker in einer Dichte von 80 bis 130 epdm, vorzugsweise in einer Dichte von 110 epdm angeordnet sind, wodurch eine ausreichende Festigkeit in Verbindung mit den Monofilamenten erreicht wird. It is advantageous if the monofilaments are arranged in the bead reinforcement in a density of 80 to 130 epdm, preferably in a density of 110 epdm, whereby a sufficient strength is achieved in connection with the monofilaments.
Vorteilhaft ist es, wenn der Wulstverstärker einlagig ausgebildet ist, da hierdurch bereits ein ausreichender Kreuzverband gebildet wird. Weitere Lagen würden Gewicht, Kosten und Rollwiderstand erhöhen, aber nicht im gleichen Maße die Wirksamkeit bezüglich der Fahreigenschaften. It is advantageous if the bead amplifier is formed in one layer, since this already a sufficient cross dressing is formed. Other layers would increase weight, cost and rolling resistance, but not the same degree of ride performance.
In einer Ausführungsform ist der Wulstverstärker zwischen Wulstkernreiter und Karkasshochschlag angeordnet. In einer alternativen Ausführungsform ist der Wulstverstärker axial außen in Bezug auf den Karkasshochschlag angeordnet. In einer wiederum alternativen Ausführungsform ist der Wulstverstärker axial innen in Bezug auf den Wulstkern angeordnet und zwischen Karkasse und Wulstkern platziert. Die hohe Wirksamkeit des Kreuzverbandes mit der Karkasse wird in allen drei vorgenannten Ausführungsformen erreicht. In one embodiment, the bead booster is disposed between bead apex and carcass turnup. In an alternative embodiment, the bead enhancer is located axially outward of the carcass turnup. In yet another alternative embodiment, the bead enhancer is disposed axially inward of the bead core and placed between the carcass and the bead core. The high effectiveness of the cross dressing with the carcass is achieved in all three aforementioned embodiments.
Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnungen, welche schematische Ausführungsbeispiele darstellen, näher beschrieben. Further features, advantages and details of the invention will now be described in more detail with reference to the drawings, which illustrate schematic embodiments.
