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 a wheel rim attached pneumatic tires and a runflat support body, which is designed as a cup-shaped ring body is and with its two axially outer edge regions on 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.On The main disadvantage of tubeless pneumatic tires is the possible occurrence a leak, causing the tire pressure to drop and the tire collapses. At a high vehicle speed can the sudden Escaping the air in the tire can lead to dangerous situations in which the driver's control over his vehicle loses. Furthermore, the tire can lose pressure thereby damaged be that the vehicle rim is in the inner soul and overlying Cuts in layers.

Ein Nachteil der dargestellten Notlaufstützkörper besteht darin, dass sie sich nicht für den Einsatz in Niederquerschnittsreifen eignen. Durch die ausgeprägten nach außen gerichteten Wölbungen des schalenförmigen Ringkörpers würden die Wölbungen im ungünstigsten Fall direkt an die Reifeninnenseite des Niederquerschnittsreifens anstoßen, wodurch die Fahreigenschaften im normalen Betriebszustand des Fahrzeugrades erheblich eingeschränkt würden. Die Federungseigenschaften würden auch bei einem kleinen Abstand zwischen dem Ringkörper und der Reifeninnenseite negativ beeinflusst werden, da u.a. das dazwischen liegende Luftpolster nur sehr klein ist.On Disadvantage of the emergency support body shown is that it not for suitable for use in low-profile tires. By the pronounced after Outside directed arches of the cupped ring body would the bulges in the worst Drop directly onto the inside of the low-profile tire bump into what the driving characteristics in the normal operating condition of the vehicle wheel significantly restricted would. The suspension properties would even with a small distance between the ring body and the inside of the tire can be negatively affected because the in between lying air cushion is only very small.
Der Erfindung liegt die Aufgabe zu Grunde, einen Notlaufstützkörper für einen Luftreifen zu schaffen, der sich insbesondere für den Einsatz bei Niederquerschnttsreifen eignet.The The invention is based on the object, an emergency running support body for To create pneumatic tires that are particularly suitable for use with low-profile tires suitable.
Gelöst wird die Aufgabe gemäß dem Oberbegriff und den kennzeichnenden Merkmalen des Anspruchs 1 dadurch, das das Querschnittsverhältnis der radialen Höhenabmessung zur axialen Breitenabmessung des Notlaufstützkörpers im Bereich zwischen 0,15 und 0,30 liegt.Is solved the task according to the generic term and the characterizing features of claim 1 in that the Aspect ratio the radial height dimension for the axial width dimension of the emergency running support body in the range between 0.15 and is 0.30.
Ein wesentlicher Vorteil der Erfindung ist insbesondere darin zu sehen, dass durch das erfindungsgemäße Querschnittsverhältnis ein optimaler Abstand zwischen Reifeninnenseite und Notlaufstützkörper erreicht wird. Auf diese Weise liegt ein Luftpolster mit einem großen Luftvolumen zwischen dem Ringkörper und der Reifeninnenseite vor, wodurch das Fahrzeugrad insgesamt nicht in seinen Federungseigenschaften beeinträchtigt wird. Durch das erfindungsgemäße Querschnittsverhältnis wird ebenfalls eine gegenüber herkömmlichen Notlaufstützkörpern unverminderte Fahrstabilität für den Pannenfall erzielt.On An essential advantage of the invention is to be seen in that by the cross-sectional ratio according to the invention optimal distance between the inside of the tire and the emergency support body has been reached becomes. In this way there is an air cushion with a large volume of air between the ring body and the inside of the tire, making the vehicle wheel overall is not impaired in its suspension properties. Due to the cross-sectional ratio according to the invention also one opposite usual Runaway support bodies undiminished driving stability for the Breakdown achieved.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Querschnittsverhältnis der radialen Höhenabmessung zur axialen Breitenabmessung des Notlaufstützkörpers im Bereich zwischen 0,20 und 0,28 liegt. In diesem Bereich liegt das Optimum, um einerseits eine einfache Montierbarkeit des Notlaufstützkörpers zu gewährleisten und um andererseits die Federungseigenschaften des Fahrzeugrades nicht zu beeinträchtigen.In An advantageous development of the invention is provided that the cross-sectional ratio the radial height dimension for the axial width dimension of the emergency running support body in the range between 0.20 and is 0.28. In this area the optimum lies on the one hand to ensure easy assembly of the emergency running support body and on the other hand the suspension properties of the vehicle wheel not to interfere.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der kleinste radiale Innendurchmesser des Ringkörpers geringfügig größer ist als der radiale Außendurchmesser am Felgenhorn. Auf diese Weise lässt sich der Notlaufstützkörper auf die Felge montieren, ohne dabei den Ringkörper plastisch zu verformen.In A further advantageous development of the invention is provided that the smallest radial inner diameter of the ring body is slightly larger than the radial outside diameter on the rim flange. That way the run-flat support body fit the rim without plastically deforming the ring body.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Ringkörper im mittleren Abschnitt des Ringkörperquerschnitts mindestens eine zur Felge gerichtete Wölbung aufweist. Dadurch wird die Montage des Notlaufstützkörpers vereinfacht, da die Stützelemente zur axialen Mitte gebogen werden können.In A further advantageous development of the invention is provided that the ring body in the middle section of the ring body cross section has at least one curvature facing the rim. This will the assembly of the emergency run support body is simplified, because the support elements can be bent to the axial center.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Ringkörper sich aus mindestens zwei Ringkörperteilen zusammensetzt. Auf diese Weise lässt sich die Herstellung des Notlaufstützkörpers vereinfachen, da die Stützelemente separat an die äußeren Ringkörperteile anvulkanisiert werden können.In a further advantageous development of the invention it is provided that the ring body is composed of at least two ring body parts. In this way, the manufacture of the emergency running support body can be simplified since the support elements attach separately to the outer ring body parts can be vulcanized.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Ringkörperteile durch eine Schweißverbindung miteinander verbunden sind. Dadurch wird eine hochfeste Verbindung zwischen den Ringkörperteilen erreicht.In A further advantageous development of the invention is provided that the ring body parts through a welded joint are interconnected. This creates a high-strength connection between the ring body parts reached.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der radiale Abstand zwischen dem radialen Außendurchmesser am Felgenhorn und dem radialen Außendurchmesser am Ringkörper mindestens die Abmessung der maximalen Wanddicke eines Stützelementes besitzt.. Auf diese Weise lässt sich der Notlaufstützkörper auf die Felge montieren, ohne dabei den Ringkörper plastisch zu verformen.In A further advantageous development of the invention is provided that the radial distance between the radial outside diameter at least on the rim flange and the radial outside diameter on the ring body has the dimension of the maximum wall thickness of a support element Way leaves the run-flat support body fit the rim without plastically deforming the ring body.
