Abstract

Running surface of a vehicle tire comprises shape retentive polymers and contains one or more tread grooves (3).

Description

Die Erfindung betrifft eine Lauffläche eines Fahrzeugreifens.The The invention relates to a tread a vehicle tire.

Die geometrischen Merkmale der Lauffläche eines Fahrzeugreifens sind üblicherweise unabhängig von der Temperatur. Die Steifigkeit des Materials steigt mit abnehmender Temperatur.The Geometric features of the tread of a vehicle tire are common independently from the temperature. The stiffness of the material increases with decreasing Temperature.

Der Erfindung liegt die Aufgabe zugrunde, eine Reifenlauffläche zu ermöglichen, die bei höheren Temperaturen eine höhere Steifigkeit aufweist.Of the Invention has for its object to enable a tire tread the at higher Temperatures a higher Having stiffness.

Die Aufgabe wird erfindungsgemäß durch die Ausbildung eines Fahrzeugreifens gemäß den Merkmalen von Anspruch 1 gelöst, bei dem die Lauffläche eines Fahrzeugreifens mit Formgedächtnispolymeren ausgebildet ist.The The object is achieved by the Forming a vehicle tire according to the features of claim 1 solved, at the tread a vehicle tire formed with shape memory polymers is.

Durch den Einsatz von Formgedächtnismaterialien innerhalb der Lauffläche lässt sich eine Änderung der Steifigkeit herbeiführen, die in Abhängigkeit von der Temperatur umschaltbar ist und bei Temperaturen oberhalb der Umschalttemperatur eine höhere, gegebenenfalls sogar gerichtete höhere Steifigkeit ermöglicht.By the use of shape memory materials inside the tread let yourself a change to cause stiffness, the dependent is switchable from the temperature and at temperatures above the switching temperature is higher, optionally even directed higher stiffness allows.

Der Einsatz der Formgedächtnispolymere kann über Copolymerisation und/oder Geometriedesign von Bauteilen erfolgen, um diese in einer zu Laufflächenmischungen kompatiblen Variante herstellen zu können.Of the Use of shape memory polymers can be via copolymerization and / or geometry design of components to make these in one to tread mixtures compatible variant to produce.

Weiterhin kann die Steifigkeit von Reifenlaufflächen über konstruktive Gestaltung der Geometrie optimiert und angepasst werden. Dabei können auch einzelne Formgedächtniselemente konstruktiv eingebunden werden.Farther Can the rigidity of tire treads over structural design optimized and adapted to the geometry. It can also be individual Shape memory elements be integrated constructively.

Die Formgedächtnispolymere sind in bevorzugter Ausführung Formgedächtnispolymere auf Basis von Polyurethan aus Diphenymethane 4,4 diisocyanate und Bisphenol A.The Shape memory polymers are in a preferred embodiment Shape memory polymers based on polyurethane from diphenymethane 4,4 diisocyanate and Bisphenol A.

Bevorzugt sind in einer oder mehreren Profilrillen eines Laufflächenprofils der Lauffläche Formgedächtnispolymere ausgebildet.Prefers are in one or more tread grooves of a tread pattern the tread Shape memory polymers educated.

Die Erfindung wird im Folgenden an Hand der in den 1 und 2 dargestellten Ausführungsbeispiele näher erläutert. Dabei zeigenThe invention will be described below with reference to in the 1 and 2 illustrated embodiments explained in more detail. Show

1 Ausschnitt eines Laufflächenprofils in Querschnittsdarstellung, 1 Section of a tread pattern in cross-sectional representation,

2 Ausschnitts eines alternativen Laufflächenprofils in Querschnittsdarstellung. 2 Section of an alternative tread profile in cross-sectional view.

Die 1 und 2 zeigen jeweils ein Laufflächenprofil 1 mit Profilrillen 3 bekannter Art, wobei im Profilgrund der Profilrillen jeweils Bauteile 2 aus einem Formgedächtnispolymer ausgebildet sind. Im Ausführungsbeispiel von 1 sind die Bauteile jeweils in hierzu ausgebildeten Ausnehmungen in den die Profilrillen begrenzenden erhabenen Profilelementen verankert. Im Ausführungsbeispiel von 2 sind diese lediglich in den Profilrillen 3 befestigt.The 1 and 2 each show a tread pattern 1 with tread grooves 3 known type, wherein in the profile base of the tread grooves each components 2 are formed from a shape memory polymer. In the embodiment of 1 the components are each anchored in recesses designed for this purpose in the raised profile elements bounding the profile grooves. In the embodiment of 2 These are only in the tread grooves 3 attached.

Durch den Einsatz von Formgedächtnismaterialien innerhalb der Lauffläche lasst sich auf diese Weise eine Änderung der Steifigkeit herbeiführen, die in Abhängigkeit von der Temperatur umschaltbar ist und bei Temperaturen oberhalb der Umschalttemperatur eine höhere, gegebenenfalls sogar gerichtete höhere Steifigkeit ermöglicht. Beispielsweise wird bei Winterreifen ermöglicht, bei Temperaturen oberhalb von 0°C eine erhöhte Steifigkeit zu erzielen.By the use of shape memory materials inside the tread let's change that way to cause stiffness, the dependent is switchable from the temperature and at temperatures above the switching temperature is higher, optionally even directed higher stiffness allows. For example, is possible with winter tires, at temperatures above 0 ° C one increased To achieve rigidity.

Die Formgedächtnispolymere sind beispielsweise Formgedächtnispolymere auf Basis von Polyurethan aus Diphenymethane 4,4 diisocyanate und Bisphenol A.The Shape memory polymers are, for example, shape memory polymers based on polyurethane from diphenymethane 4,4 diisocyanate and bisphenol A.
