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.

Bei einteiligen Notlaufstützkörpern ohne Flansche kann hingegen das Problem auftreten, dass diese Notlaufstützkörper eine axial ausgerichtete Verbindungsnaht aufweisen, die im Pannenfall eine Schwachstelle darstellen kann. Bei einer hohen Belastung des Notlaufstützkörpers im Pannenfall kann der Fall eintreten, dass der Notlaufstützkörper an dieser Verbindungsstelle versagt. Des Weiteren ist diese Verbindungsstelle bei der Herstellung des metallischen Ringkörpers einer hohen Belastung ausgesetzt, die ggf. zu einem Ausschuss des Ringkörper-Zwischenproduktes führen kann.at one-piece runflat support bodies without flanges However, the problem may occur that these runflat support a axially aligned seam, which in case of breakdown a Vulnerability. At a high load of the emergency running support in the In the event of a breakdown, it is possible for the emergency running support to engage this connection point fails. Furthermore, this connection point exposed to a high load in the manufacture of the metallic ring body, which may possibly lead to a reject of the ring-body intermediate.
Der Erfindung liegt die Aufgabe zu Grunde, einen Notlaufstützkörper für einen Luftreifen mit einer hohen Festigkeit zu schaffen.Of the Invention is the object of an emergency running support for a To create pneumatic tires with a high strength.
Gelöst wird die Aufgabe gemäß den kennzeichnenden Merkmalen des Anspruchs 1 dadurch, dass der Ringkörper eine Schweißnaht aufweist, wobei die Schweißnaht in der Aufsicht mit der axialen Achse des Ringkörpers einen Winkel größer als 0° bildet oder die Schweißnaht in der Aufsicht in Form einer Kurvenlinie mit mindestens einer Krümmung verläuft.Is solved the task according to the characterizing Characteristics of claim 1, characterized in that the annular body a Weld having, wherein the weld in the plan view with the axial axis of the annular body an angle greater than 0 ° forms or the weld in the plan view in the form of a curved line with at least one curvature.
Ein Vorteil ist insbesondere darin zu sehen, dass der erfindungsgemäße Notlaufstützkörper eine hohe Festigkeit aufweist. Durch den schrägen bzw. nichtlinearen Verlauf der Schweißnaht besitzt die Verbindungsstelle im Ringkörper sehr gute Festigkeitseigenschaften, wobei die beim Umformprozess auftretenden Spannungsspitzen wesentlich gleichmäßiger auf die Umfangsfläche des Ringkörpers verteilt werden. Dadurch entsteht bei der Herstellung des metallischen Ringkörpers weniger Ausschuss. Im Pannenfall ergeben sich für die Festigkeit des Notlaufstützkörpers analoge Vorteile. Die im Betriebszustand des Notlaufstützkörpers auftretenden Spannungsspitzen werden wiederum gleichmäßiger über die Umfangsfläche des Ringkörpers verteilt, wodurch der Notlaufstützkörper insgesamt eine höhere Pannenlaufleistung besitzt.One The advantage is in particular to be seen in that the emergency running support according to the invention a high Has strength. Due to the oblique or non-linear course the weld has the joint in the ring body very good strength properties, wherein the voltage peaks occurring during the forming process substantially more evenly the peripheral surface of the ring body be distributed. This results in the production of the metallic ring body less committee. In the event of a breakdown, the stability of the emergency running support is analogous Advantages. The voltage peaks occurring in the operating state of the emergency running support body become even more uniform over the peripheral surface of the ring body distributed, causing the runflat support body in total a higher one Has breakdown performance.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Winkel zwischen der Schweißnaht und der axialen Achse zwischen 30° und 70° beträgt. Dieser Winkelbereich lässt sich bei der Herstellung des Ringkörpers einfach realisieren und bietet eine ausreichende Festigkeitssteigerung des Notlaufstützkörpers.In an advantageous embodiment of the invention is provided that the angle between the weld and the axial axis between 30 ° and 70 °. This Angle range leaves easy to implement in the manufacture of the ring body and offers a sufficient increase in strength of the emergency running support.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Schweißnaht in der Aufsicht in Form einer Sinuskurve verläuft.In a further advantageous embodiment of the invention is provided that the weld is in the supervision in the form of a sinusoid runs.
Auf diese Weise wird das wellenförmige Querschnittsprofil des Notlaufstützkörpers nachgebildet, so dass sich beim Umformprozess optimale Dehnungen des Ringkörpers einstellen können.On this way, the wave-shaped cross-sectional profile of the emergency running support model, so that optimum deformation of the ring body is achieved during the forming process can.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Schweißnaht durch ein Laserschweißverfahren oder ein WIG-Schweißverfahren erzeugt wird.In a further advantageous embodiment of the invention, it is provided that the weld produced by a laser welding method or a TIG welding method.
Diese An der Verschweißungen bieten ausgezeichnete Festigkeitseigenschaften.These At the welds offer excellent strength properties.
