Description
Die Erfindung betrifft einen Fahrzeugluftreifen mit JThe invention relates to a pneumatic vehicle tire with J
einer auf die Profilstollen und/oder -rippen der Lauffläche aufgebrachten Schicht. Solche Schichten sollen die Laufflächen bei bekannten Reifen dahingehend verbessern, daß Risse am Grund der Rillen der Lauffläche verhütet werden, oder daß solche Risse vor dem Eindringen von schädlichen Stoffen geschützt werden. Hierzu wird die Schicht vorwiegend auf den Boden der Profilrillen aufgelegt und besteht aus Material von geringer Härte und dafür umso größerer Weichheit bzw. Zähigkeit.a layer applied to the tread lugs and / or ribs of the tread. Such layers are supposed to improve the treads in known tires to the effect that cracks at the bottom of the grooves of the tread be prevented, or that such cracks are protected from the ingress of harmful substances. This is done the layer is mainly placed on the bottom of the profile grooves and consists of material of low hardness and therefore all the greater softness and toughness.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, die scharfen seitlichen Oberkanten der Profilstollen und/oder -rippen zu erhalten, die das Durchschneiden eines etwa vorhandenen Schmierfilms auf der Straße bewerkstelligen sollen. 909822meU HIn contrast, the invention is based on the object of maintaining the sharp lateral upper edges of the tread lugs and / or ribs, which are intended to cut through any existing lubricating film on the road. 909822meU H
Zur Lösung dieser Aufgabe sind die bekannten Maßnahmen nicht geeignet. Es zeigt sich, daß sich die Stollenkanten nach nicht allzulanger Reifenlaufzeit durch die elastische Verformung der Stollen selbst und durch die Rauheit der Straßenoberfläche abrunden, und daß damit ihre Schärfe verlorengeht und der gewünschte Durchdringungseffekt und die dadurch erzielte Erhöhung der Rutschsicherheit nicht mehr erreicht wird.The known measures are not suitable for solving this problem. It turns out that the edges of the cleats after the tire has not been running for too long elastic deformation of the lugs themselves and round off by the roughness of the road surface, and that with it their sharpness is lost and the desired penetration effect and the resulting increase in slip resistance is no longer achieved.
Die Erfindung besteht darin, daß die Seitenflächen der " Profilstollen und/oder -rippen einen durch die Vulkanisation fest mit dem Laufflächengummi verbundenen Überzug aus einer sehr abriebfesten und vorzugsweise hart en Mischung haben.The invention consists in the fact that the side surfaces of the "tread cleats and / or ribs" result in a vulcanization Cover made of a very abrasion-resistant and preferably have a tough mix.
Ein einfaches Verfahren zur Herstellung eines Fahrzeugluftreifens nach der Erfindung besteht darin, daß auf der Lauffläche eine im Verhältnis zur Laufflächendicke dünne Folie aus einer entsprechenden Mischung aufgelegt wird, und daß beim spätesrer>Heizprozeß die Folie durch die Formteile der Heizform zum Teil auf die Stollenoberfläche und zwangsläufig in die entstehende Profilrille gepreßt wird. Die Stollen des Reifens erhalten so einen allseitigen, durch die Vulkanisation fest mit dem Laufflächengummi verbundenen Überzug. Durch den höheren Abriebwiderstand und die höhere Härte dieser Schicht behalten die Profilstollenkanten ihre scharf en Durchdringungskanten und gewährleisten damit die Rutschsicherheit des Reifens.A simple method for producing a pneumatic vehicle tire according to the invention is that on the The tread is thin in relation to the tread thickness Foil from an appropriate mixture is placed, and that during the later> heating process, the foil through the Molded parts of the heating mold partly on the tunnel surface and inevitably in the resulting profile groove is pressed. The lugs of the tire are given an all-round bond with the rubber tread due to the vulcanization associated coating. Due to the higher abrasion resistance and the higher hardness of this layer the tread edges keep their sharp penetration edges and thus guarantee slip resistance of the tire.

In der Zeichnung let:In the drawing let:
Pig. 1 ein Schnitt durch eine Reifenpartie bei einem aus der Fertigung kommenden ReifenPig. 1 shows a section through a section of tires in one coming out of production tires
Pig. 2 ein Schnitt durch die gleiche Partie eines Reifens bei einem anderen Herstellungsverfahren. Pig. 2 shows a section through the same part of a tire in a different manufacturing process.
Es sind die Karkasse mit 1, die Karkassgewebefäden mit 2, die Lauffläche mit 3, die Stollen mit 4, die Rillen mit 5, die Stollenoberfläche mit 6, die Stollenseitenfläche mit 7, und der überzug mit 8 gekennzeichnet.There are the carcass with 1, the carcass fabric threads with 2, the tread with 3, the cleats with 4, the grooves with 5, the cleat surface with 6, the cleat side surface marked with 7, and the cover marked with 8.
Der Überzug 8 war ursprünglich eine Folie, die auf die r-ohe Lauffläche aufgelegt war. Diese Schicht 8 wurde beim Vulkanisieren des Reifens in der geheizten Form zugleich mit den Rillen 5 in die Lauffläche eingeformt, so daß sie nicht mehr den Rillengrund 9» sondern nur noch die Seitenflechen 7 und die radiale Außenfläche 10 der Stollen 4 bedeckt. Dadurch sind die Kanten 12 der Stollen von der Schicht 8 überzogen.The cover 8 was originally a film that was placed on the red tread. This layer 8 was when the tire is vulcanized in the heated mold, it is molded into the tread at the same time as the grooves 5, so that they no longer have the groove base 9 'but only the side patches 7 and the radial outer surface 10 of the cleats 4 covered. As a result, the edges 12 of the studs are covered by the layer 8.
Es ist nicht zu vermeiden, daß bei diesem Herstellungsverfahren der Oberzug 8 auf den Seitenflächen nach dem Rillengrund zu schwächer wird und bei Annäherung an den Rillengrund unterbrochen wird bzw. aufhört. Diese Schwächung kann deshalb in Kauf genommen werden, weil der Belag mit zunehmenden Stollenverschleiß wegen der entsprechenden Verringerung der elastischen Verformung der abgebrauchten Stollen einer geringeren Verschleißbeanspruchung unterworfen ist.It is unavoidable that in this manufacturing process, the upper run 8 on the side surfaces after Groove base becomes too weaker and is interrupted or stops when approaching the groove base. These Weakening can therefore be accepted because the surface with increasing wear of the lugs because of the corresponding reduction in elastic deformation the worn tunnel is subject to less wear and tear.

Dennoch ist die Ausbildung der Lauffläche nach der Fig. 2 anzustreben. In Fig. 2 ist die auf die Seitenwände aufgelegte Schicht mit 14 bezeichnet. Diese Schicht hat überall die gleiche Stärke. Sie kann in dieser Form beispielsweise hergestellt werden, in-dem man die Seitenwände 7 der Stollen in einer Zwischenoperation mit einer Folie belegt, um dann erst den endgültigen* Formund Vulkanisationsvorgang folgen zu lassen.Nevertheless, the formation of the running surface according to FIG. 2 is desirable. In Fig. 2 is placed on the side walls Layer denoted by 14. This layer has the same thickness everywhere. It can be produced in this form, for example, by removing the side walls 7 the cleat is covered with a film in an intermediate operation, and only then is the final * Formund Let vulcanization process follow.
