Abstract

Tire has a lateral surface, which encircles a hollow space after application of tire on the tire rim and a shell which encases the hollow space. The hollow space is partly encircled by the lateral surface of the tire and is completely filled with a flexible foam material. Independent claims are included for the following: (1) Wheel for a vehicle; and (2) Vehicle e.g. motor vehicle.

Description

Die vorliegende Erfindung liegt auf dem technischen Gebiet der Fahrzeugtechnik und betrifft genauer einen Reifen für ein Fahrzeug, insbesondere Kraftfahrzeug.The The present invention is in the technical field of vehicle technology and more specifically relates to a tire for a vehicle, in particular a motor vehicle.

In der Fahrzeugtechnik werden herkömmlicher Weise schlauchlose Reifen mit einem Druckgas, insbesondere Druckluft, befüllt. Bekannt ist außerdem das Befüllen der Reifen mit gasförmigem Stickstoff, wodurch der Rollwiderstand des Reifens geringfügig verringert werden kann.In the vehicle technology become more conventional Way tubeless tires with a pressurized gas, especially compressed air, filled. It is also known the filling the tire with gaseous Nitrogen, whereby the rolling resistance of the tire slightly reduced can be.

Nachteilig ist hierbei vor allem die Tatsache, dass der Reifendruck regelmäßig überprüft und gegebenenfalls erhöht werden muss, was für den Fahrer mit einem gewissen Aufwand verbunden ist. Zudem muss im Falle einer Undichtigkeit des Reifens das Rad gewechselt werden, da ansonsten die Reifenfelge Schaden nehmen kann. Tritt eine solche Undichtigkeit eines Reifens bei einer höheren Fahrzeuggeschwindigkeit auf, so kann das Fahrzeug auch gänzlich unkontrollierbar sein, mit entsprechenden Folgen für Fahrzeuginsassen und Fahrzeug.adversely Here is mainly the fact that the tire pressure is checked regularly and if necessary elevated must be, what for the driver is associated with a certain effort. In addition, must in case of tire leakage the wheel will be changed otherwise the tire rim can be damaged. Kick one Leakage of a tire at a higher vehicle speed on, so the vehicle can also completely be uncontrollable, with corresponding consequences for vehicle occupants and vehicle.

Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, einen Reifen zur Verfügung zu stellen mit dem die vorgenannten Nachteile einer regelmäßigen Wartung und die Folgen einer Reifenundichtigkeit vermieden werden können.In contrast there is the object of the present invention is to provide a tire provide with the aforementioned disadvantages of regular maintenance and the consequences of tire leakage can be avoided.

Diese Aufgabe wird nach dem Vorschlag der Erfindung durch einen Reifen für ein Fahrzeug, insbesondere Kraftfahrzeug, mit den Merkmalen des unabhängigen Anspruchs gelöst.These Task is according to the proposal of the invention by a tire for a Vehicle, in particular motor vehicle, with the features of the independent claim solved.

Erfindungsgemäß ist ein Reifen zum Aufbringen auf eine Reifenfelge eines Fahrzeugs, insbesondere Kraftfahrzeugs, gezeigt, welcher mit einer Mantelfläche versehen ist, die nach Aufbringen des Reifens auf die Reifenfelge gemeinsam mit der Reifenfelge einen Hohl- bzw. Innenraum umgrenzt. Eine solche Mantelfläche ist typischer Weise aus einer Lauffläche und zwei angrenzenden Seitenwänden mit innenliegenden Wülsten aufgebaut.According to the invention is a Tire for application to a tire rim of a vehicle, in particular Motor vehicle, shown, which provided with a lateral surface is common after applying the tire to the tire rim bounded with the tire rim a hollow or interior. Such lateral surface is typically composed of a tread and two adjacent side walls internal beads built up.

Der erfindungsgemäße Reifen zeichnet sich nun in wesentlicher Weise dadurch aus, dass der von der Mantelfläche des Reifens teilweise umgebene Hohlraum vollständig mit einem elastischen Schaummaterial befüllt ist. Insofern wird bei dem erfindungsgemäßen Reifen auf die Anwendung eines Druckgases, wie Druckluft, zur Befüllung des Reifens verzichtet und anstelle dessen das elastische Schaummaterial eingesetzt.Of the inventive tire is now characterized by the fact that the of the lateral surface The cavity partially surrounded by the tire completely with an elastic Foam material filled is. In this respect, in the tire according to the invention on the application a compressed gas, such as compressed air, dispensed to fill the tire and instead use the elastic foam material.

Hierbei können das elastische Schaummaterial bzw. dessen Materialeigenschaften im Allgemeinen so gewählt sein, dass dieses geeignet ist, die Eigenschaften des herkömmlicher Weise eingesetzten Druckgases, beispielsweise Druckluft oder gasförmiger Stickstoff, nachzubilden. Insbesondere ist das Schaummaterial elastisch, da der mit elastischem Schaummaterial befüllte Reifen, wie der mit Druckgas befüllte Reifen, eine gewisse Nachgiebigkeit bzw. Verformbarkeit haben muss. Generell sind jedoch die Fahreigenschaften des erfindungsgemäßen Reifens, wie Reifendruck Rollwiderstand, Geräuschentwicklung und dergleichen, durch eine Veränderung der Materialeigenschaften des elastischen Schaummaterials in einer gewünschten Weise einstellbar.in this connection can the elastic foam material or its material properties generally chosen this way be that this is suitable, the properties of the conventional Used compressed gas, such as compressed air or gaseous nitrogen, replicate. In particular, the foam material is elastic because the filled with elastic foam material tires, such as with compressed gas filled Tire, must have a certain flexibility or deformability. In general, however, the driving characteristics of the tire according to the invention, such as tire pressure rolling resistance, noise and the like, through a change the material properties of the elastic foam material in one desired Way adjustable.

Durch die erfindungsgemäße Befüllung des Reifens mit einem elastischen Schaummaterial kann in vorteilhafter Weise eine größere Pannensicherheit erreicht werden, da insbesondere der Reifen nicht mehr platzt, weil bei Befüllung des Reifens mit einem elastischen Schaummaterial kein Überdruck im Innern des Reifens vorhanden ist. Wenn der erfindungsgemäße Reifen beschädigt wird, beispielsweise indem ein Nagel in den Reifen eingefahren wird, bleibt der Reifen aufgrund der Befüllung mit dem elastischen Schaummaterial in Form und das Fahrzeug ist noch kontrollierbar.By the filling of the tire according to the invention With an elastic foam material can advantageously achieved a greater puncture safety be, especially since the tire does not burst, because when filling the Tire with an elastic foam material no overpressure is present inside the tire. When the tire of the invention damaged is, for example, by a nail is retracted into the tire remains the tire due to the filling with the elastic foam material in shape and the vehicle is still controllable.

Die Erfindung erstreckt sich ferner auf ein Rad für ein Fahrzeug, insbesondere Kraftfahrzeug, welches mit einem wie oben beschriebenen Reifen auf einer Reifenfelge ausgerüstet ist. Das elastische Schaummaterial füllt den durch die Mantelfläche des Reifens und die Reifenfelge definierten Hohl- bzw. Innenraum die Reifenfelge vollumfänglich umgebend vollständig aus. Ferner erstreckt sich die Erfindung auf ein Kraftfahrzeug, welches mit wenigstens einem solchen Rad ausgerüstet ist.The The invention further extends to a wheel for a vehicle, in particular Motor vehicle, which with a tire as described above equipped with a tire wheel is. The elastic foam material fills the through the lateral surface of the tire and the tire rim defined hollow or interior the tire rim full completely surrounding out. Furthermore, the invention extends to a motor vehicle, which is equipped with at least one such wheel.
