Abstract

The invention is based on pneumatic radial ply vehicle tyres having a radial carcass and, above the belt, a ply comprising two adjacent strips which are composed of filaments of a heat-shrinking material running in the circumferential direction of the tyre. In order to achieve improved running properties in the case of these tyres and good manufacturing possibilities in tyre production, the two strips touch each other or are a distance apart which is however only up to about 15 % of the belt width. The individual strips can, however, be applied individually, so that the effect of a solid ply is produced, but additionally with increased dynamic pliableness in the area of the centre of the tread.

Description

GürtelreifenRadial tire

Die Erfindung betrifft einen Gürtelreifen (Fahrzeugluftreifen) mit Radialkarkasse und einer nahe oberhalb des Gürtels befindlichen Bandage aus zwei nebeneinanderliegenden, sich in Reifenumfangsrichtung erstreckenden Bändern, deren einander parallele Fäden oder dergl. praktisch in Reifenumfangsrichtung verlaufen und aus einem wärmeschrumpfenden Material bestehen. Insbesondere betrifft die Erfindung solche Gürtelreifen dieser Art, bei denen der Gürtel aus mehreren Stahlseillagen aufgebaut ist.The invention relates to a radial tire (pneumatic vehicle tire) with Radial carcass and a bandage made of two near above the belt adjacent bands extending in the tire circumferential direction, whose parallel threads or the like. Run practically in the tire circumferential direction and made of a heat shrinkable material. In particular, the invention relates such radial tires of this type, in which the belt consists of several steel cable layers is constructed.

Bei bekannten Gürtelreifen sind die aus wärmeschrumpfendem Material bestehenden Bänder lediglich im Bereich der Gürtelränder wirksam. Die Bänder, die im Vergleich zur Giirtelbreite etwa ein Drittel dieser Breite ausmachen, überragen die Gürtelkanten. Sie haben die Aufgabe, beim Herstellungsvorgang des Reifens Verwerfungen der Gürtelränder zu vermeiden, die bei grobstolligen Reifen eintreten können.Known radial tires are made of heat-shrinkable material existing ligaments only effective in the area of the belt edges. The tapes that make up about a third of this width in comparison to the belt width the belt edges. Their job is to avoid warping during the tire manufacturing process to avoid the edges of the belt, which can occur with coarse tires.

Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, durch die vorerwähnte Bandage die Laufeigenschaften des Reifens zu verbessern und im Vergleich zu einlagigen, sich etwa über die Gürtelbreite erstreckenden Gürteln eine verbesserte Konfektion (Aufbauen des Reifens) zu gewährleisten.The invention is essentially based on the object by The aforementioned bandage to improve the running properties of the tire and in comparison to single-ply belts extending roughly across the width of the belt, an improved one To ensure assembly (building the tire).

Zur Lösung dieser Aufgabe haben erfindungsgemäß die beiden Bänder der Bandage eine solche Breite, daß sie sich mit ihren einander zugekehrten Rändern berühren. Ferner ist es möglich, die beiden Bänder so zueinander anzuordnen, daß ihr gegenseitiger Abstand bis zu etwa 15 % der Gürtelbreite ausmacht.According to the invention, the two belts have to solve this problem the bandage is so wide that it fits with your each other touch the facing edges. It is also possible to align the two bands with one another to arrange that their mutual distance is up to about 15% of the belt width.

Somit ist eine sich im wesentlichen über die Gürtelbreite erstreckende Wirkung der Bandage möglich. Gegenüber den sogenannten Vollbandagen, also solchen Bandagen, die sich über die gesamte Gürtelbreite erstrecken, ergibt sich aber der Vorteil einer größeren dynamischen Weichheit in der Laufflächenmitte. Zugleich ergibt sich aufgrund der Erfindung der Vorteil einer verbesserten Konfektion; die nicht zu vermeidenden unterschiedlichen Durchmesser, auf denen die vorerwähnten Bänder anzuordnen sind, führen nicht zu unerwünschten Verwerfungen der Festigkeitsträger der erwähnten Bänder. Wellungen dieser Bänder in den Randbereichen auf vergleichsweise kleinem Durchmesser sind ausgeschlossen.Thus it is one that extends essentially across the belt width Effect of the bandage possible. Compared to the so-called full bandages, i.e. those Bandages that extend over the entire belt width, however, result from the Advantage of greater dynamic softness in the middle of the tread. At the same time results Due to the invention, the advantage of an improved assembly; they don't different diameters to be avoided on which the aforementioned tapes are to be arranged, do not lead to undesired warping of the reinforcements of the tapes mentioned. Corrugations of these bands in the edge areas on comparatively small diameters are excluded.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung dargestellt, in der ein Ausführungsbeispiel wiedergegeben ist.Further details of the invention are shown with reference to the drawing, in which an embodiment is shown.

Es zeigen: Fig. 1 einen Fahrzeugluftreifen als Riesenluftreifen für Lastfahrzeuge gedacht im radialen Teilschnitt und Fig. 2 eine Draufsicht auf den Gürtel und die Bandage des Reifens gemäß Figur 1.1 shows a pneumatic vehicle tire as a giant pneumatic tire for Trucks thought in radial partial section and FIG. 2 is a plan view of the Belt and the bandage of the tire according to Figure 1.

Der aus Gummi oder gummil-ihnlichen Stoffen bestehende Reifenkörper wird durch eine Radialkarkasse verfestigt, deren radial verlaufende Stahlseile 1 in den Reifenwülsten durch Umschlingen der dort befindlichen.ulstkerne 2 verankert sind. In der Reifenzenitpartie zwischen dem Laufstreifen 3 und den Stahlseilen 1 befindet sich der Gürtel 4, der sich praktisch über die Breite des Laufstreifens 3 erstreckt und in Reifenumfangsrichtung zugfest ausgeführt ist. Die drei Gürtellagen 5, 6 und 7 mit den einander parallelen Stahlseilen 8 sind so angeordnet, daß die Stahlseile 8 benachbarter Gürtellagen 5, 6 und 7 Dreiecke bilden.The tire body made of rubber or rubber-like materials is strengthened by a radial carcass whose radial steel cables 1 anchored in the tire beads by looping around the bead cores 2 located there are. In the tire tread between the tread 3 and the steel cables 1 is the belt 4, which is practically across the width of the tread 3 extends and is designed to be tensile in the tire circumferential direction. The three belt layers 5, 6 and 7 with the parallel steel cables 8 are arranged so that the Steel cables 8 adjacent belt layers 5, 6 and 7 form triangles.

Dabei verlaufen die Stahlseile 8 der Lagen 5 und 6 unter einem ° Winkel von 18 bis 22 zur Reifenumfangsrichtung, jedoch von Lage zu Lage entgegengesetzt schr ansteigend unter Bildung eines Kreuzverbandes, während die Stahlseile 8 der Lage 7 mit der Reifenumfangsrichtung Winkel von etwa 650 einschließen.The steel cables 8 of the layers 5 and 6 run at an angle from 18 to 22 to the tire circumferential direction, but opposite from layer to layer increasing steeply to form a cross connection, while the steel cables 8 of the Enclose layer 7 with the tire circumferential direction angle of about 650.

Nahe oberhalb dieses Gürtelverbandes befinden sich zwei Bänder 9 etwa gleicher Breite, die symmetrisch in bezug auf die Laufstreifen- bzw. Gürtelmitte angeordnet sind und in der Gürtelmitte entweder praktisch zusammenstoßen oder aber - wie in Figur 2 dargestellt - mit einem geringen gegenseitigen Abstand verlegt sind, der etwa 10 % der Breite B des Gürtels 4 ausmacht.Near above this belt association there are two bands 9 approximately the same width, which is symmetrical with respect to the center of the tread or belt are arranged and either practically collide in the middle of the belt or else - as shown in Figure 2 - laid with a small mutual distance which is about 10% of the width B of the belt 4.

Die Bänder 9 bestehen aus einander parallelen Polyamidcordfäden 11, die praktisch in Reifenumfangsrichtung verlaufen und eine Bandage für den Gürtelverband bilden.The bands 9 consist of parallel polyamide cords 11, which run practically in the circumferential direction of the tire and a bandage for the belt bandage form.

Für die beiden vergleichsweise breiten Bänder 9 ergeben sich die Wirkungen einer sogenannten Vollbondage jedoch mit verbesserten dynamischen Eigenschaften in der Lufflächenmittelzone. Die beiden Bänder 9 gestatten zudem eine faltenfreie Verlegung und Anordnung auch für den Fall, daß - wie in der Zeichnung dargestellt - die Bänder 9 nicht eben, achsparallel, sondern zur Rotationsach.se des Reifens hin geneigt oder gekrümmt verlaufen.The effects result for the two comparatively wide bands 9 a so-called full bondage, however, with improved dynamic properties in the air surface center zone. The two bands 9 also allow a wrinkle-free Laying and arrangement also in the event that - as shown in the drawing - The bands 9 are not flat, axially parallel, but to the rotational axis of the tire be inclined or curved.

In den äußeren Randbereichen der Bänder 9, also dort, wo ihre kleinsten Innendurchmesser sind, werden Faltenbildungen oder Wellen nicht entstehen können.In the outer edge areas of the bands 9, that is, where their smallest Inner diameter, wrinkles or waves will not occur.
