Fahrzeugluftreifen Vehicle tires

Die Erfindung betrifft einen Fahrzeugluftreifen mit einer weitestgehend luftdicht ausgeführten Innenschicht und mit einem in seinem Inneren an der dem Laufstreifen gegenüberliegenden Innenfläche haftend angebrachten, schallabsorbierenden Schaumstoffring, wobei der Schaumstoffring an einer vorab aufgebrachten The invention relates to a pneumatic vehicle tire with a largely airtight running inner layer and with an inside of the tread opposite inner surface adhered, sound-absorbing foam ring, wherein the foam ring applied to a pre-applied

Klebmittellage haftet. Ein derartiger Fahrzeugluftreifen ist beispielsweise aus der EP-A-1 659 004 bekannt. Der beispielsweise aus Polyurethanschaum bestehende Ring wird mittels eines Klebers, welcher aus einem in einem Lösungsmittel gelösten synthetischen Adhesive layer adheres. Such a pneumatic vehicle tire is known, for example, from EP-A-1 659 004. The existing example of polyurethane foam ring is by means of an adhesive which consists of a dissolved in a solvent synthetic

Der Rubber may be made, attached to the inner surface of the tire. It is also possible to attach the foam ring by means of suitable adhesives. Of the

Schaumstoffring reduziert die Geräuschabgabe des Reifens sowohl in den Foam ring reduces the noise emission of the tire both in the

Fahrzeuginnenraum als auch in die Fahrzeugumgebung. Vehicle interior as well as in the vehicle environment.

Jedoch ist durch die Anordnung des Schaumstoffringes die thermische als auch die mechanische Belastung des Fahrzeugluftreifens erhöht. Dieses ist insbesondere für die Hochgeschwindigkeitshaltbarkeit des Reifens nachteilig. However, the arrangement of the foam ring, the thermal and the mechanical load of the pneumatic vehicle tire is increased. This is particularly detrimental to the high speed durability of the tire.

Der Erfindung liegt die Aufgabe zu Grunde, einen Fahrzeugluftreifen mit einem in seinem Inneren angeordneten Schaumstoffring zur Verfügung zu stellen, dessen Hochgeschwindigkeitshaltbarkeit mit denjenigen baugleichen Fahrzeugluftreifen ohne Schaumstoffring vergleichbar ist. Gelöst wird die gestellte Aufgabe erfindungs gemäß dadurch, dass die Klebmittellage im Zusammenspiel mit dem Schaumstoffring eine weitestgehende Luftdichtigkeit aufweist und dass etwa in Projektion des Schaumstoffringes keine Innenschicht angeordnet ist. The invention is based on the object to provide a pneumatic vehicle tire with a foam ring arranged in its interior, the high-speed durability of which is comparable to those identical pneumatic vehicle tire without foam ring. The object is achieved fiction, in accordance with the fact that the adhesive layer in conjunction with the foam ring has a largely airtightness and that, for example, in projection of the foam ring no inner layer is arranged.

Erfindungswesentlich ist, dass etwa im Bereich des Schaumstoffringes, also radial außen in Bezug auf den Schaumstoffring, auf die Innenschicht verzichtet ist. Die Innenschicht reicht somit mit einem ersten Abschnitt - im Reifenquerschnitt betrachtet - vom linken Reifenwulst über die Seitenwand etwa bis zum linken Ende des Schaumstoffringes. Im Bereich des Schaumstoffringes ist auf die Innenschicht verzichtet. Der zweite Abschnitt der Innenschicht reicht etwa vom rechten Ende des Schaumstoffringes über die Seitenwand bis zum rechten Reifenwulst. Es hat sich überraschenderweise gezeigt, dass die Hochgeschwindigkeitshaltbarkeit durch dieses Weglassen der Innenschicht im Zenit des Reifens verbessert ist, weil hierdurch der Wärmeaufbau im Reifen reduziert ist. Auf die luftdicht ausgeführte Innenschicht kann im Zenit des Reifens verzichtet werden, weil der Schaumstoffring in It is essential to the invention that the inner layer is dispensed with, for example, in the region of the foam ring, that is to say radially outward in relation to the foam ring. The inner layer thus extends with a first section - viewed in the tire cross section - from the left tire bead over the side wall approximately to the left end of the foam ring. In the area of the foam ring is dispensed with the inner layer. The second section of the inner layer extends approximately from the right end of the foam ring over the side wall to the right tire bead. It has surprisingly been found that the high-speed durability is improved by this omission of the inner layer in the zenith of the tire, because this heat is reduced in the tire. On the airtight running inner layer can be omitted in the zenith of the tire, because the foam ring in

Kombination mit der diesen Schaumstoffring haftend haltenden Klebmittelschicht eine ausreichende Luftdichtigkeit erreicht. Zudem ist durch das Weglassen der Innenschicht im Zenit des Reifens an Materialkosten eingespart.  Combined with the adhesive layer holding this foam ring sufficient air tightness achieved. In addition, the omission of the inner layer in the zenith of the tire saves material costs.

Vorteilhaft ist es, wenn die Klebmittellage ein Dichtmittel, vorzugsweise ein It is advantageous if the adhesive layer is a sealant, preferably a

Polyurethan-Gel ist oder eine viskose Mischung auf Basis eines Butylkautschukes, eines Polybutens oder auf Basis von Silikon ist. Die Klebmittellage wird gleichzeitig als ein zur selbsttätigen Abdichtung vorgesehenes Dichtmittel verwendet. Das Dichtmittel ist eine selbsthaftende, viskose Dichtmasse mit einer starken Klebrigkeit, welche Einstiche von bis zu 5 Millimetern Durchmesser selbständig abdichtet. Nach einem Durchstich durch den Laufstreifen bis durch in den Reifeninnenraum umschließt das Dichtmittel den eingedrungenen Fremdkörper vollständig, dichtet den Innenraum gegenüber der Umgebung ab und verhindert so einen Druckluftverlust des Reifens. In einer anderen Ausführung der Erfindung ist die Klebmittellage an sich weitestgehend luftdicht ausgeführt, wodurch eine zusätzliche Sicherheit bei einem Verrutschen des Schaumstoffringes erhalten ist. Vorteilhaft ist es, wenn der Schaumstoffring eine Breite von 50 mm bis 190 mm, vorzugsweise eine Breite von etwa 120 mm aufweist, wobei die Breite in axialer Richtung gemessen ist. Es ist eine maximale Schallabsorption bei geringst möglichem Wärmeaufbau erzielt. Vorteilhaft ist es, wenn die Klebmittellage eine größere Breite als die Breite des Schaumstoffringes aufweist, so dass die Klebmittellage zwischen 2 mm und 8 mm, vorzugweise etwa 5 mm über jedes der beiden Enden des Schaumstoffringes hinausreicht, wobei die Breite in axialer Richtung gemessen ist. Es ist die Polyurethane gel is or is a viscous mixture based on a butyl rubber, a polybutene or based on silicone. The adhesive layer is simultaneously used as a sealant intended for automatic sealing. The sealant is a self-adhesive, viscous sealant with a strong tack, which self-seals punctures of up to 5 millimeters in diameter. After a puncture through the tread through through into the tire interior, the sealant completely encloses the invaded foreign body, seals the interior from the environment, thus preventing a loss of compressed air of the tire. In another embodiment of the invention, the adhesive layer is designed to be largely airtight, thereby providing additional security in a slipping of the foam ring is obtained. It is advantageous if the foam ring has a width of 50 mm to 190 mm, preferably a width of about 120 mm, wherein the width is measured in the axial direction. It is a maximum sound absorption achieved with the least possible heat build-up. It is advantageous if the adhesive layer has a greater width than the width of the foam ring, so that the adhesive layer extends between 2 mm and 8 mm, preferably about 5 mm beyond each of the two ends of the foam ring, wherein the width is measured in the axial direction. It is the

Dichtwirkung bei Produktionstoleranzen sichergestellt. Sealing effect ensured at production tolerances.

Vorteilhaft ist es, wenn die Breite des innenschichtlosen Bereiches unterhalb des Schaumstoffringes geringer als die Breite des Schaumstoffringes ist, so dass die Innenschicht und der Schaumstoffring an jedem Ende des Schaumstoffringes eine Überlappung zwischen 2 mm und 8 mm, vorzugsweise von etwa 5 mm aufweisen. It is advantageous if the width of the inner layerless region below the foam ring is less than the width of the foam ring, so that the inner layer and the foam ring at each end of the foam ring have an overlap between 2 mm and 8 mm, preferably of about 5 mm.
