Abstract
Description
Die Erfindung betrifft eine Anordnung zur Beeinflussung einer Auflagefläche eines Fahrzeugreifens.The The invention relates to an arrangement for influencing a support surface a vehicle tire.
Die Größe der Auflagefläche eines Fahrzeugreifens, also die Teilfläche der Lauffläche, die im Kontakt mit der Fahrbahn steht, beeinflusst zusammen mit dem Profil und der Gummirezeptur wesentlich den Kraftstoffverbrauch, den Bremsweg und die Traktion des Fahrzeugs, auf dem der Reifen montiert ist, sowie den Verschleiß, die Temperatur und die Geräuschemission des Fahrzeugreifens. Die Auflagefläche ist durch den Druck der im Reifen befindlichen Luft oder des Füllgases beeinflussbar, der meist im Bereich zwischen 1.5 bar und 3 bar liegt. Wird dieser Druck so gewählt, dass eine der genannten Eigenschaften, beispielsweise der Verschleiß, optimiert ist, gilt dies im Allgemeinen nicht für jede der anderen Eigenschaften, beispielsweise Bremsweg und Traktion. Angestrebt wird daher eine von einer Fahrsituation abhängige Größe der Auflagefläche.The Size of the bearing surface of a vehicle tire, So the part of the tread that is in contact with the roadway, influenced along with the profile and the rubber formulation significantly reduces fuel consumption, the braking distance and the traction of the vehicle on which the tire is mounted, as well as the wear, the temperature and the noise emission of the vehicle tire. The bearing surface is due to the pressure the air in the tire or the filling gas can be influenced, which is usually in the range between 1.5 bar and 3 bar. Will this pressure chosen so that one of the properties mentioned, for example the wear is optimized, this is generally true not for each of the other properties, for example Braking distance and traction. The aim is therefore a dependent on a driving situation Size of the bearing surface.

Der Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte Anordnung zur Beeinflussung einer Auflagefläche eines Fahrzeugreifens anzugeben.Of the Invention is therefore the object of an improved arrangement for influencing a bearing surface of a vehicle tire specify.
Die Aufgabe wird erfindungsgemäß gelöst durch eine Anordnung mit den Merkmalen des Anspruchs 1.The The object is achieved by an arrangement with the features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Bei einer erfindungsgemäßen Anordnung zur Beeinflussung einer Auflagefläche eines Fahrzeugreifens ist im Inneren des Fahrzeugreifens in einem Übergangsbereich zwischen je einer von zwei Seitenwänden zu einer Lauffläche des Fahrzeugreifens umlaufend je ein Hochdruckschlauch angeordnet. Beide Hochdruckschläuche sind mit einem unter einem steuerbaren oder regelbaren Druck stehenden Gas, beispielsweise Luft oder einem anderen Füllgas beaufschlagbar. Die beiden Hochdruckschläuche können zu diesem Zweck miteinander in Verbindung stehen, so dass nur eine Zuleitung benötigt wird.at an inventive arrangement for influencing a bearing surface of a vehicle tire is inside of the vehicle tire in a transition region between one each from two side walls to a tread the vehicle tire circumferentially arranged each have a high-pressure hose. Both high-pressure hoses are with one under a controllable one or controllable pressurized gas, such as air or a another fill gas acted upon. The two high-pressure hoses can For this purpose communicate with each other, so that only one Supply line is needed.
Bei einer so gestalteten Anordnung kann der Druck infolge des, verglichen mit dem Reifenvolumen, geringen Volumens der Hochdruckschläuche situationsabhängig sehr schnell geändert werden. Beispielsweise wird der Druck für eine schnelle Autobahnfahrt so erhöht, dass die Lauffläche verformungsresistenter wird und sich so eine möglichst geringe Auflagefläche (auch Latsch genannt) des Fahrzeugreifens durch Verringerung ihrer Ausdehnung in einer Longitudinalrichtung (Rollrichtung) bei nahezu gleichbleibender Ausdehnung in einer dazu rechtwinkligen Transversalrichtung ergibt. Auf diese Weise vermindert sich die Reibung und damit der Kraftstoffverbrauch und Verschleiß des Fahrzeugreifens infolge verringerter so genannter Walkarbeit. Bei einer Bremsung kann der Druck hingegen sehr schnell so abgesenkt werden, dass sich die Auflagefläche mit dem Ziel einer erhöhten Reibung gegenüber der Fahrbahn vergrößert. Ebenso kann eine schnelle Anpassung der Auflagefläche in anderen Fahrsituationen erfolgen.at a so-designed arrangement, the pressure as a result of, compared with the tire volume, low volume of high pressure hoses depending on the situation be changed very quickly. For example, the pressure for a fast highway ride so increased that the tread becomes more resistant to deformation and so on the smallest possible contact surface (also Laces called) of the vehicle tire by reducing its extent in a longitudinal direction (rolling direction) at almost constant Expansion in a perpendicular transverse direction results. In this way reduces the friction and thus the fuel consumption and wear of the vehicle tire due to reduced so-called flexing work. When braking, the pressure can be be lowered very quickly so that the bearing surface with the goal of increased friction against the road increased. Likewise, a quick adjustment the bearing surface in other driving situations done.
