The invention further relates to a pneumatic vehicle tire.
Gürtellagen in Fahrzeugluftreifen sind üblicherweise mit Stahlkorden verstärkt. Dabei setzt sich jede Gürtellage aus in eine Gummimischung, der Gürtelaufpressmischung, eingebetteten, untereinander parallel verlaufenden Stahlkorden zusammen. Die Gürtellagen sind meist zueinander derart angeordnet, dass die Stahlkorde in der einen Lage die Stahlkorde in der anderen Lage kreuzen und jeweils unter einem bestimmten Winkel, bei PKW-Reifen in der Größenordnung von etwa 25°, zur Umfangsrichtung des Reifens verlaufen. LKW-Reifen weisen üblicherweise vier Gürtellagen auf, PKW-Reifen zwei Gürtellagen und eine die radial äußerste Gürtellage abdeckende Bandage, deren Festigkeitsträger beispielsweise aus Nylon bestehen und in Umfangsrichtung des Reifens orientiert sind. Diese 0°-Lage wird bevorzugt als Spulbandage aufgebracht, bei der ein Streifen aus in Gummi eingebetteten Nylonfäden spiralförmig um den aufgebrachten Gürtel gewickelt wird.belt plies in pneumatic vehicle tires are common reinforced with steel cords. This is where every belt position in a rubber compound, the belt-pressing mixture, embedded, mutually parallel steel cords together. The belt plies are usually arranged to each other such that the steel cords in one layer crossing the steel cords in the other layer and under each a certain angle, with car tires of the order of magnitude of about 25 °, extend to the circumferential direction of the tire. Truck tires usually have four belt layers on, car tires two belt layers and one covering the radially outermost belt ply Bandage, whose reinforcement For example, consist of nylon and in the circumferential direction of the tire are oriented. This 0 ° position is preferably applied as Spulbandage, in which a strip made of rubber-embedded nylon threads is wound spirally around the applied belt.

Die Stahlverstärkungen in Fahrzeugluftreifen tragen zu einem erheblichen Anteil am Gesamtgewicht des Reifens bei. Das Gewicht der Reifen erhöht auch entsprechend das Gewicht der Fahrzeuge, wobei der Treibstoffverbrauch mit dem Gewicht korreliert.The steel reinforcements in pneumatic vehicle tires contribute to a significant proportion of the total weight of the tire. The weight of the tires also increases the weight accordingly vehicles, with fuel consumption correlated with weight.
Insbesondere bei LKW-Reifen, die höheren Belastungen im Betrieb ausgesetzt sind, spielt auch die Gürtelhaltbarkeit, vorzugsweise im Bereich der Gürtelkanten, eine Rolle. Es ist ferner schon vorgeschlagen worden, Korde aus hochmoduligen Materialien. als Festigkeitsträger in den Gürtellagen von Reifen zu verwenden, wobei jedoch die geringe Biegesteifigkeit von Korden aus solchen Materialien, wie beispielsweise Korde aus Carbon oder Aramidfasern, nachteilig ist.Especially in truck tires, the higher loads Operational also plays the belt durability, preferably in the area of the belt edges, a role. It has also been proposed to make cords high modulus materials. as reinforcement in the belt layers of tires, but with low flexural rigidity cords made of such materials as cords Carbon or aramid fibers, is disadvantageous.
