Abstract

A cross-ply tyre has its plies on the carcase layers which cross at an anger of 40-80 degrees, these plies consist of an approximately circumferential layer of steel cord wires and crossed fabric cord layers on top. Design gives a comfortable long-life tyre with good action, high resistance at its shoulder without using a large amt. of expensive high strength reinforcements.

Description

Gürtelreifen Radial tire

Die Erfindung bezieht sich auf einen Luftreifen in Gürtelbauweise, der sich bei sonst gleichem Niveau des Fahrverhaltens eines Stahlgürtelreifens durch besonders gute Komforteigenschaften und geringen Laufgummiverschleiß sowie durch verbesserte Haltbarkeit und Widerstandsfähigkeit im Bereich der Gürtelkanten auszeichnet, Es ist bekannt, daß Luftreifen in Stahlgürtelbauweise erhebliche Vorteile in Bezug auf Rollwiderstand, Seitenführungskraft, Lebensdauer usw. gegenüber Textilgürtelreifen und erst recht gegenüber Diagonalreifen aufweisen. Bei bestimmten Straßenzuständen und Geschwindigkeiten sind jedoch die den Fahrkomfort mitbestimmenden Dämpfungseigenschaften solcher Reifen nicht zufriedenstellend, insbesonders dann, wenn die Federung und Dämpfung des Fahrwerkes nicht optimal darauf abgestimmt sind. Andererseits stellen die geschnittenen Kanten der gekreuzten Stahlcordgürtellagen eine Unstetigkeit im Festigkeitsverband des Reifenkörpers dar mit der Folge, daß die Reifenschulterzone bei außergewahnlichen Einsatzfällen und Betriebsbedingungen erheblich gefährdet sein kann.The invention relates to a pneumatic tire in belt construction, which works with a steel belt tire with otherwise the same level of driving behavior particularly good comfort properties and low rubber wear as well as through characterized by improved durability and resistance in the area of the belt edges, It is known that pneumatic tires in steel belt construction have significant advantages in terms of on rolling resistance, cornering force, service life, etc. compared to textile belted tires and even more so compared to diagonal tires. With certain road conditions and speeds are, however, the damping properties that determine driving comfort Such tires are not satisfactory, especially when the suspension and The suspension damping of the chassis is not optimally matched to it. On the other hand, ask the cut edges of the crossed steel cord belt layers show a discontinuity in the Strength association of the tire body with the result that the tire shoulder zone considerably endangered in exceptional cases of application and operating conditions can be.

Es ist weiterhin bekannt, daß man zum Schutz dieser Schulterzonen und zur Erhöhung der Schnellauftüchtigkeit über den gekreuzten Stahlcordlagen eine die Kanten abdeckende Bandage anbringt, die meist aus einer Nyloncordlage mit in Umfangsrichtung verlaufenden Fäden besteht. Dieser zusätzliche Materialeinsatz bedeutet mehr Gewicht und verteuert den Reifen material- und fertigungsseitig.It is also known that one can protect these shoulder areas and to increase the speed of use over the crossed steel cord layers attaching bandage covering the edges, which is usually made of a nylon cord layer with in There is thread running in the circumferential direction. This additional use of material means more weight and makes the tire more expensive in terms of material and production.

Zur Verbesserung des Verschleißverhaltens ist -wie auch seit längerem bekannt - vorgeschlagen worden, die gekreuzten Lagen aus Stahlcord durch zwei oder mehr Lagen aus in Umfangsrichtung angeordneten, nebeneinanderliegenden Stahlcorden zu ersetzen. Ein solcher Reifen ist aber nicht in der Lage, Seitenkräfte in ausreichendem Maße aufzubringen und ein einwandfreies, präzises Lenken zu ermöglichen.To improve the wear behavior - as has been the case for a long time known - it has been proposed to cut the crossed layers of steel cord by two or more layers of steel cords arranged next to one another in the circumferential direction to replace. However, such a tire is not able to withstand sufficient lateral forces Apply dimensions and enable flawless, precise steering.

Die Aufgabe, einen komfortablen, langlebigen Reifen zu schaffen, dessen Fahrverhalten einwandfrei und dessen Schulterzone widerstandsfähiger als bei bekannten Konstruktionen ohne substantiellen Mehraufwand an Festigkeitsträgern ist, wird gelöst durch Umkehrung der Bauweise "gekreuzter Stahlcord mit Nylon-Bandage".The task of creating a comfortable, long-lasting tire, its Driving behavior flawless and its shoulder zone more resistant than known Constructions without substantial additional expenditure on reinforcement is solved by reversing the construction "crossed steel cord with nylon bandage".

Der erfindungsgemäße Reifen ist ein Luftreifen in Gürtelbauweise mit einer Karkasse aus mindestens 2 Lagen textilen Cordes, vorzugsweise Nylon, wobei die Corde dieser Lagen sich in einem Winkel von 400 bis 800, vorzugsweise 600 bis 700, kreuzen.The tire of the present invention is a belt type pneumatic tire with a carcass made of at least 2 layers of textile cords, preferably nylon, wherein the cords of these layers are at an angle of 400 to 800, preferably 600 to 700, cross.

Der Gürtel wird gebildet aus einer Lage Stahlcord, deren Krümmungsradius im Reifenquerschnitt größer als das Doppelte des Reifendurchmessers ist und deren Drähte in einem sehr spitzen Winkel zur Umfangsrichtung, d.h. annähernd 0 bis 100 verlaufen. Über dieser Stahlcordlage befinden sich zwei Lagen textilen Cordes, deren Einzelfäden unter einem Winkel von 120 bis 300 gekreuzt sind. Diese beiden textilen Gürtellagen sind breiter als die Stahlcordbandage und überdecken deren Rand an beiden Seiten. Insbesondere können die beiden textilen Gürtellagen durch Faltung eines schräggeschnittenen Streifens hergestellt sein.The belt is made from a layer of steel cord with a radius of curvature in the tire cross-section is greater than twice the tire diameter and their Wires at a very acute angle to the circumferential direction, i.e. approximately 0 to 100 get lost. Over this steel cord layer there are two layers of textile cords Single threads are crossed at an angle of 120 to 300. These two textile Belt layers are wider than the steel cord bandage and cover the edge on both Pages. In particular, the two textile belt layers can be folded by folding one be made obliquely cut strip.

Ein in dieser Weise aufgebauter Reifen übertrifft hinsichtlich Abrollweichheit, Verschleißfestigkeit und Haltbarkeit in der Schulterzone die sonst üblichen Stahlcord-Gürtelkonstruktionen, während Lenkungs- und Seitenführungseigenschaften infolge der Kreuzungskombination von Stahlcordlagen und darüberliegenden Textilcordlagen gleichwertig sind.A tire constructed in this way outperforms in terms of rolling softness, Wear resistance and durability in the shoulder zone the otherwise usual steel cord belt constructions, while steering and cornering properties as a result of the intersection combination of steel cord layers and overlying textile cord layers are equivalent.

In den Abbildungen 1 und 2 ist der Aufbau beispielsweise dargestellt. Die Abb. 1 zeigt den Querschnitt des erfindungsgemäßen Reifens. Die Abb. 2 zeigt eine Draufsicht auf die Festigkeitsträger des erfindungsgemäßen Reifens.In Figures 1 and 2, the structure is shown as an example. Fig. 1 shows the cross section of the tire according to the invention. Fig. 2 shows a plan view of the strength members of the tire according to the invention.

Abb. 1 zeigt den kopfnahen Teil eines Reifenquerschnittes mit Laufstreifen 1, Seitenteilen 2, Polsterstreifen 3 und Innenseele 4. Über der Karkasse 5, die aus 2 gekreuzten Lagen Textilcord besteht, befindet sich der Gürtel. Dieser ist aus einer Lage Stahlcord 6 und zwei sich kreuzenden Textilcordlagen 7 aufgebaut.Fig. 1 shows the head-near part of a tire cross-section with treads 1, side panels 2, upholstery strips 3 and inner liner 4. Above the carcass 5, the consists of 2 crossed layers of textile cord, is where the belt is. This is composed of a layer of steel cord 6 and two intersecting textile cord layers 7.

Letztere überdecken die Stahlcordlage an deren Rändern 8a und 8b um 1/5 bis 1/10 der Breite der Stahlcordlage.The latter cover the steel cord layer at its edges 8a and 8b 1/5 to 1/10 of the width of the steel cord layer.

Der Krümmungsradius R der Stahlcordlage ist doppelt so groß wie der Reifendurchmesser.The radius of curvature R of the steel cord layer is twice as large as that Tire diameter.

Abb. 2 verdeutlich den Verlauf der Fäden bzw. Drähte der einzelnen Verstärkungslagen, d.h. der Karkasse 5, der Stahlcordlage 6 und der beiden Textilcordlagen 7.Fig. 2 illustrates the course of the threads or wires of the individual Reinforcement layers, i.e. the carcass 5, the steel cord layer 6 and the two textile cord layers 7th
