Abstract
Description
Die Erfindung betrifft ein Fahrzeugrad mit einem auf einer Radfelge befestigten Luftreifen und einem Notlaufstützkörper, der als schalenförmiger Ringkörper ausgebildet ist und sich mit seinen beiden axial äußeren Randbereichen über ringförmige Stützelemente auf der Radfelge abstützt.The The invention relates to a vehicle wheel with one on a wheel rim attached pneumatic tire and a Notlaufstützkörper, which is designed as a cup-shaped annular body is and with its two axially outer edge regions via annular support elements supported on the wheel rim.
Ein wesentlicher Nachteil von schlauchlosen Luftreifen ist das mögliche Auftreten einer Undichtigkeit, wodurch der Luftdruck im Reifen abfällt und der Reifen kollabiert. Bei einer hohen Fahrzeuggeschwindigkeit kann das plötzliche Entweichen der Luft im Reifen zu gefährlichen Situationen führen, in denen der Fahrer die Kontrolle über sein Fahrzeug verliert. Ferner kann der Reifen bei einem Druckverlust dadurch beschädigt werden, dass die Fahrzeugfelge sich in die Innenseele und darüber liegende Lagen einschneidet.One major disadvantage of tubeless pneumatic tires is the possible occurrence a leak, causing the air pressure in the tire drops and the tire collapses. At a high vehicle speed can the sudden Escape the air in the tire to cause dangerous situations in which the driver is in control loses his vehicle. Further, the tire may be at a pressure loss damaged by it be that the vehicle rim in the inner soul and overlying Cuts in layers.

Ein Nachteil der dargestellten Notlaufstützkörper besteht darin, dass zwischen dem Notlaufstützkörper und dem Reifen oder der Felge eine relative Bewegung zueinander möglich ist. Eine nachträgliche Positionsverschiebung des Notlaufstützkörpers in Umfangrichtung des Fahrzeugrades, beispielsweise während des Fahrbetriebes, kann bedeuten, dass sich das Massenträgheitsmoment des gesamten Fahrzeugrades verändert. Dies hätte eine statische und dynamische Unwucht des Fahrzeugrades zur Folge, wodurch ein erneutes Auswuchten des Fahrzeugrades erforderlich wäre.One Disadvantage of the illustrated emergency running body is that between the emergency running support and the tire or the rim relative movement is possible to each other. An afterthought Positional shift of the emergency running support in the circumferential direction of Vehicle wheel, for example, during of driving, can mean that the moment of inertia the entire vehicle wheel changed. This would have a static and dynamic unbalance of the vehicle wheel result, whereby a re-balancing of the vehicle wheel would be required.
Der Erfindung liegt die Aufgabe zu Grunde, einen Notlaufstützkörper für einen Luftreifen zu schaffen, der auf eine einfache Art und Weise eine stabile Fixierung des Notlaufstützkörpers im Fahrzeugrad gewährleistet.Of the Invention is the object of an emergency running support for a To create pneumatic tires, which in a simple way a stable Fixation of the emergency running support in Vehicle wheel guaranteed.
Gelöst wird die Aufgabe gemäß dem Oberbegriff und den kennzeichnenden Merkmalen des Anspruchs 1 dadurch, dass mindestens ein Stützelement im Berührungsbereich zur Innenseite des Reifenwulstes des Luftreifens eine Verdrehsicherung gegenüber dem anliegenden Luftreifen aufweist.Is solved the task according to the generic term and the characterizing features of claim 1, characterized in that at least one support element in the contact area to the inside of the tire bead of the tire anti-rotation across from having the applied pneumatic tire.
Ein wesentlicher Vorteil der Erfindung ist insbesondere darin zu sehen, dass dadurch eine stabile Fixierung des Notlaufstützkörpers im Fahrzeugrad erreicht wird. Durch die Verdrehsicherung wird eine form- und kraftschlüssige Verbindung zwischen dem Stützelement und dem anliegenden Reifenwulst erzielt, so dass der Notlaufstützkörper sich nicht mehr in Umfangsrichtung gegenüber dem Reifen verdrehen kann. Da der Reifenwulst kraftschlüssig fest mit der Felge in Verbindung steht, ist damit das gesamte System aus Felge, Reifen und Notlaufstützkörper fest miteinander verbunden. Auf diese Weise ist nach dem einmaligen Auswuchten kein weiteres zusätzliches Auswuchten des Fahrzeugrades mit dem erfindungsgemäßen Notlaufstützkörper mehr erforderlich.One a significant advantage of the invention is to be seen in particular in that thereby a stable fixation of the emergency running in the Vehicle wheel is reached. Due to the anti-rotation lock, a form- and non-positive Connection between the support element achieved and the adjacent tire bead, so that the emergency running support itself can not twist in the circumferential direction relative to the tire. Because the tire bead frictionally firmly connected to the rim, so is the whole system made of rim, tires and emergency running firm connected with each other. In this way, after the one-time balancing no further additional Balancing the vehicle wheel with the emergency running support according to the invention more required.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Oberfläche der Stützelemente ein Profil als Verdrehsicherung aufweisen. Die Stützelemente lassen sich auf eine einfache Art und Weise mit einem Profil versehen, beispielsweise durch eine entsprechende Formgebung bei der Herstellung der Stützelemente.In an advantageous embodiment of the invention is provided that the surface the support elements have a profile as anti-rotation. The support elements can be provided in a simple way with a profile, for example, by a corresponding shaping in the production the support elements.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Profil der Stützelemente komplementär zu den Luftabführrillen auf der Innenseite des Luftreifens ausgeführt sind. Durch die komplementäre Ausgestaltung der Profilkonturen greifen diese formschlüssig ineinander, wodurch eine sehr stabile und feste Verbindung zwischen Reifenwulst und Stützelement erreicht wird.In a further advantageous embodiment of the invention is provided that the profile of the supporting elements complementary to the Luftabführrillen on the inside of the tire are executed. Due to the complementary design the profile contours engage in a form-fitting manner, whereby a very stable and firm connection between tire bead and support element is reached.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Profil der Stützelemente und das der Luftabführrillen kantenförmig ausgebildet ist. Die kantenförmige Ausgestaltung der Profilkonturen erhöht die Festigkeit der formschlüssigen Verbindung zwischen Reifenwulst und Stützelement.In a further advantageous embodiment of the invention is provided that the profile of the supporting elements and the Luftabführrillen shaped edges is trained. The edge-shaped Design of the profile contours increases the strength of the positive connection between tire bead and support element.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Oberflächen der Stützelemente mit einer Materialschicht mit einem hohen Reibungswert beschichtet sind. Beispielsweise könnten die Außenflächen des Stützelementes mit einer sandpapierartigen Materialschicht versehen werden, wodurch ein hoher Reibungswert zwischen Reifenwulst und Stützelement erzielt wird. Der hohe Reibungswert unterstützt die kraftschlüssige Verbindung und gewährleistet dadurch eine feste Fixierung des Notlaufstützkörpers.In a further advantageous embodiment of the invention, it is provided that the surfaces of the support elements are coated with a layer of material having a high coefficient of friction. at For example, the outer surfaces of the support element could be provided with a sandpaper-like material layer, whereby a high coefficient of friction between the tire bead and the support element is achieved. The high friction value supports the non-positive connection and thus ensures a firm fixation of the emergency running support body.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Stützelemente mit einer Materialschicht mit Festigkeitsträgern versehen sind. Diese Materialschicht trägt zu einer höheren Stabilität der Stützelemente bei, wodurch diese in einer Notlaufsituation eine hohe Last aufnehmen können.In a further advantageous embodiment of the invention is provided that the support elements are provided with a material layer with reinforcements. This material layer contributes a higher one stability the support elements in which they take a high load in a runflat situation can.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Notlaufstützkörper mit einem Sensorelement zur Anzeige einer Notlaufsituation versehen ist. Das Sensorelement hat die Funktion, eine Notlaufsituation zu detektieren. Anschließend soll dem Fahrer des Fahrzeuges diese Notlaufsituation angezeigt werden.In a further advantageous embodiment of the invention is provided that the emergency running support with provided a sensor element for displaying a runflat situation is. The sensor element has the function of an emergency running situation detect. Subsequently the driver of the vehicle should see this emergency running situation become.
