Abstract

Automobile type has a slip-resistant tread that contains a large number of small crystals or grains of a hard matl. e.g. corundum, embedded in the surface profiles, esp. profiles of crosslinked polyurethane. Retains its rough tread surface, adn thus good gripping action, as the tread wears away. Does not damage street surfaces. More resistant to wear than metal spikes.

Description

Reifen mit rutschfester Lauffläche für kraftfahrzeuge.Non-slip tires for motor vehicles.

Die Erfindung betrifft einen Reifen iür Kraftfahrzeuge, dessen Lauffläche besonders griffig ausgeführt ist. Bei Reifen für Kraftfahrzeuge ist es erforderlich, daß die Lautfläche so ausgeführt ist, daß das Fahrzeug auch bei glatter Straße, besonders bei Eis und Schnee, möglichst nicht rutschen kann.The invention relates to a tire for motor vehicles, the tread of which is particularly easy to grip. In the case of tires for motor vehicles, it is necessary that the sound surface is designed in such a way that the vehicle can move even on a slippery road, especially in ice and snow, can not slide if possible.

Es ist bekannt, daß zur Erfüllung dieser Erfordernisse die Reifen von Kraftfahrzeugen ait besonders grobes Profil versehen werden, z. B. bei den sogenannten M+S-Rei£en. Es ist ferner bekannt daß die Lauffläche lit Stahlstiften bestückt wird, die z. B. bei vereister Straße eine gute Haftung auf der Bahrbahn gewährleisten. Es handelt sich ul die sogenannten Spikes-Reifen.It is known that in order to meet these requirements the tires be provided by motor vehicles ait particularly coarse profile, z. B. in the so-called M + S journeys. It is also known that the tread is equipped with steel pins, the z. B. ensure good adhesion on the roadway on icy roads. It concerns ul the so-called spiked tires.

Die M+S-Reifen haben den Nachteil, daß sie bei verdster Straße nicht besonders wirksau sind. Die Spikes-Reifen sind zwar auf vereister und schnee glatter Straße gut wirksam, gestatten jedoch auch dann, wenn der Strßenzustand es zulassen würde, keine besonders hoheu Geschwindigkeiten, da die Stahlstifte dann aus den Reifen geschleudert werden können. Ferner verurschen die Spikes-Reifen auf normaler Straße eine Beschädigung der Straßenoberfläche. Die Spikes-Reifen haben ferner den Nachteil, daß sich die Stahlstifte auf eis- und schneetreier Straße rasch abnutzen.The M + S tires have the disadvantage that they cannot be used on dirty roads are particularly effective. The spiked tires are smoother on icy and snowy surfaces Road works well, but also when the road conditions allow it would not have particularly high speeds because the steel pins would then come out of the Tires can be thrown. Furthermore, the spiked tires erur on normal Road damage to the road surface. The studded tires also have the Disadvantage that the steel pins wear out quickly on roads with no ice or snow.

Der Erfindung liegt die Aufgabe zugrunde, die Nachteile der bekannten Reifen für Kraftfahrzeuge, insbesondere der M+S- sowie Spikes-Reifen, zu vermeiden. Diese Auf gabe wird erfindungsgemäß dadurch gelöst, daß in die Lauffläche bis zur Tiefe des in dieselbe eingeschnittenen Profils kleine Kristalle oder Körner aus harter Material (z. B. Korund) in großer Anzahl eingelagert sind.The invention is based on the disadvantages of the known Avoid tires for motor vehicles, especially M + S and spiked tires. This task is achieved according to the invention in that in the tread up to Depth of the profile cut into it from small crystals or grains hard material (e.g. corundum) are stored in large numbers.

Um den in die Lauffläche eingelagerten Kristallen oder Körnern einen festen Halt zu geben, ist der Reifen in einer weiteren Ausbildung der Erfindung so ausgeführt, daß die Lauffläche deselbon aus andere Material besteht al der übrige Teil des Reifens.Around the crystals or grains embedded in the running surface To give a firm hold is the tire in a further embodiment of the invention designed so that the tread deselbon consists of a different material than the rest Part of the tire.

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden in folgenden näher beschrieben.Two embodiments of the invention are shown in the drawing and are described in more detail below.

Fig. 1 zeigt einen Schnitt durch einen Reifen tür Kraftfahrzeuge. Die Lauffläche "a" ist bis zur Tiefe des Profils mit Kristallen oder Körnern "b", die in das Grundmaterial (z. B. Gummi) eingelagert sind, versehen. Die eingelagerten Kristalle oder Körner nutzen sich langsamer ab als das Grundiaterial und ragen daher ihrer etwas aus der Lauffläche des Reifens heraus, solange sie noch Halt in Grundmaterial haben. Auf diese Weise behält die Lauffläche des Reifens immer eine rauhe Oberfläche und darit gute Griffigkeit, die besonders auf vereister Straße ein Rutschen des Reifens auf derselben weitgehend verhindert.Fig. 1 shows a section through a tire for motor vehicles. The tread "a" is to the depth of the profile with crystals or grains "b", which are embedded in the base material (e.g. rubber). The stored Crystals or grains wear off more slowly than the base material and therefore protrude its somewhat out of the tread of the tire as long as it still holds in base material to have. In this way the tread of the tire always keeps a rough surface and good grip, which prevents slipping, especially on icy roads Tire largely prevented on the same.

kig. 2 zeigt einen Schnitt durch einen Reifen, dessen Lauffläche "a" aus besondere reißfesten Material (z.B.kig. 2 shows a section through a tire whose tread "a" made of special tear-resistant material (e.g.

einea vernetzten Polyurethan) besteht und somit die Rristalle "b" besonders gut festhält. Diese Lauf fläche ist entlang der Fläche "c" durch Kleben, Vulkanisieren oder in anderer geeigneter Weise iit den Reifen verbunden.a cross-linked polyurethane) and thus the crystals "b" holds particularly well. This running surface is glued along the surface "c", Vulcanizing or otherwise bonded to the tire in a suitable manner.
