Description

UNIROYAL ENGLEBERT J ^': * : :; :UNIROYAL ENGLEBERT J ^': * : : ; : Reifen GmbH * G213Tires GmbH * G213 Fahrzeugluftrei fenVehicle pneumatic tires

Die Neuerung bezieht sich auf einen Fahrzeugluftreifen in Radialbauart mit einer Radialkarkasse, dessen profilierter Laufstreifen durch eine gürtelartige Einlage verstärkt ist, die gebildet wird aus einem Faltgürtel, der eine weitere Gürtellage umfaßt und aus einer radial außen angeordneten Abdecklage, die mindestens so breit ist wie der freie Abstand zwischen den Faltenden der Faltlage.The innovation relates to a pneumatic vehicle tire of radial design with a radial carcass, the profiled tread of which is reinforced by a belt-like insert, which is formed from a folding belt, which comprises a further belt layer and from a cover layer arranged radially on the outside, which is at least as wide as the free distance between the fold ends of the fold layer.

Derartige Gürtelkonstruktionen sind bekannt. Sie werden insbesondere bei Hochgeschwindigkeitsreifen angewandt, da sie neben einer günstigen Laufstreifenverstärkung ein hoch geeignetes Mittel darstellen, das die Randtrennung der Gürtel lagen weitgehend einschränkt.Such belt constructions are well known. They are used in particular in high-speed tires, as they represent not only a cost-effective tread reinforcement but also a highly suitable means of largely limiting the edge separation of the belt layers.

Der Neuerung liegt die Aufgabe zugrunde, eine solche Gürteleinlage so leichtgewichtig wie möglich auszubilden und deren Hochbeanspruchbarkeit in Bezug auf Zug- und Biegefestigkeit beizubehalten, wobei sie im Zentral bereich durch eine geeignete Abdecklage bandagenartig fest eingebunden vorliegen soll.The innovation is based on the task of making such a belt insert as lightweight as possible and maintaining its high resilience in terms of tensile and bending strength, whereby it should be firmly bound in the central area like a bandage by a suitable covering layer.

Dadurch sind an Reifeneigenschaften vorhanden: Hochgeschwindigkeitseignung, hoher Fahrkomfort, geringer Rollwiderstand und hoher Widerstand gegen Gürtelrandtrennung sowie Schutz gegen Feuchtigkeit.This means that the tire has the following properties: high speed capability, high driving comfort, low rolling resistance and high resistance to belt edge separation as well as protection against moisture.

Neuerungsgemäß wird die Aufgabe dadurch gelöst, daß der Faltgürtel und die von diesem umfaßte weitere Gürtel lage aus aromatischem Polyamidkord bestehen und daß die Abdecklage aus Polyamid- oder Polyestereinfachgarn besteht.According to the innovation, the problem is solved in that the folding belt and the further belt layer encompassed by it consist of aromatic polyamide cord and that the cover layer consists of polyamide or polyester single yarn.

Hierdurch sind zusätzlich zu den vorgenannten Reifeneigenschaften aufgrund der gewählten Materialien eine Leichgewichtkonstruktion und eine feste Bandagierung durch die unter Wärmeeinwirkung schrumpfenden, unter 0° Orientierung vorliegenden Garnelemente vorhanden.In addition to the tire properties mentioned above, the materials selected provide a lightweight construction and a firm bandage thanks to the yarn elements that shrink under the influence of heat and are oriented at 0°.

Die Neuerung ist an Hand von Ausführungsbeispielen erläutert. EsThe innovation is explained using examples.

Fig. 1 einen Querschnitt durch eine Faltgürtel konstruktion,Fig. 1 a cross section through a folding belt construction, Fig. 2 einen Querschnitt durch eine weitere Faltgürtel konstruktion.Fig. 2 shows a cross section through another folding belt construction.

Der Fahrzeugluftreifen 1 nach Fig. 1 mit einer Radialkarkasse 2 und einem profilierten Laufstreifen 3 ist mit einer gürtelartigen Verstärkungseinlage 4 versehen. Diese Einlage besteht aus der gefalteten Gürtel lage 5, die aromatische Polyamidkorde aufweist, deren FaItenden 6 die Gürtelbreite b des Reifens bestimmen. Die Faltlage 5 um-' faßt eine weitere Gürtellage 7 ebenfalls aus aromatischem Polyamidkord. Dieses Material weist die höchste spezifische Zugfestigkeit aller nichtmetallischen Gürtelfestigkeitsträgerelemente auf, ist in der Bruchfestigkeit vergleichbar mit Stahl, ist jedoch etwa fünfmal leichter als Stahl. Die Faltbereiche der Einlage sind mit 8 und deren Enden mit 9 bezeichnet.The pneumatic vehicle tire 1 according to Fig. 1 with a radial carcass 2 and a profiled tread 3 is provided with a belt-like reinforcing insert 4. This insert consists of the folded belt layer 5, which has aromatic polyamide cords, the folded ends 6 of which determine the belt width b of the tire. The folded layer 5 comprises a further belt layer 7, also made of aromatic polyamide cord. This material has the highest specific tensile strength of all non-metallic belt strength carrier elements, is comparable to steel in terms of breaking strength, but is about five times lighter than steel. The folded areas of the insert are designated 8 and their ends 9.

In dem Frei raum zwischen den Enden 9 des Faltgürtels ist eine Abdecklage angeordnet. Die Abdecklage 10 besteht aus Einfachfäden aus Polyamid; z.B. des Typs 1400/1 dtex. Sie kann auch aus Polyester- Einfachfäden bestehen. Die Fäden sind parallel zu der Umfangsmittenlinie x-x, d.i. 0° Orientierung, angeordnet. Sie sind ebenfalls sehr leicht und weisen Schrumpfeigenschaft unter Wärmeeinwirkung auf. Dadurch ist die leichgewichtige, hochfeste und elastische Gürtel konstruktion der Einlage 4 fest eingebunden und erhöht dadurch die Festigkeit und Stabilität des Fahrzeugluftreifens 1.A cover layer is arranged in the free space between the ends 9 of the folding belt. The cover layer 10 consists of single threads made of polyamide, e.g. of type 1400/1 dtex. It can also consist of single polyester threads. The threads are arranged parallel to the circumferential center line x-x, i.e. 0° orientation. They are also very light and have shrinkage properties when exposed to heat. This firmly binds the lightweight, high-strength and elastic belt construction of the insert 4 and thereby increases the strength and stability of the pneumatic vehicle tire 1.

Der Fahrzeugluftreifen 11 nach Fig. 2 entspricht im wesentlichen der Ausführung 1. Hierbei ist lediglich die Abdecklage 10 gering die Faltenden 9 der Faltlage 5 überlappend angeordnet.The pneumatic vehicle tire 11 according to Fig. 2 essentially corresponds to the version 1. In this case, only the cover layer 10 is arranged to slightly overlap the fold ends 9 of the fold layer 5.
