Abstract

The pneumatic tyre is provided with an emergency running ring of an elliptical cross section. The ring touches the inner side walls above the rim horns, and its inner diameter is slightly greater than that of the rim horns. The ring is fitted to a normal well based rim using an inflatable tube. The tube fits between the rim base wall and the emergency ring, and is inflated by a valve. The space between the emergency ring and the tyre is inflated by a second valve.

Description

ahrzeugradvehicle wheel

Die Erfindung betrifft ein F?hrzeugrad mit einem im Reifenhohlraum befindlichen, bezüglich seines Durchmessers im wesentlichen unveränderbaren Notlaufring.The invention relates to a vehicle wheel with a tire cavity located, with respect to its diameter essentially unchangeable emergency ring.

Diese Notlaufringe kennen nur d?nn ihre Aufgabe erfüllen, wenn sie imstande sind, die Radlast zu tragen. Dies ist aber nur dann möglich, wenn sich der Luftreifen auf dem Notlaufring und dieser wiederum auf der Innenfläche des Luftreifens und/oder der Außenfläche der Felge ilbstiitzen kann.These run-flat rings only know how to do their job when they are are able to carry the wheel load. But this is only possible if the pneumatic tire on the run-flat ring and this in turn on the inner surface of the pneumatic tire and / or the outer surface of the rim.

Eine Schwierigkeit bei der Verwirklichung dieser Fahrzeugräder besteht i der Montage des Notlaufringes; ist die Felge ungeteilt, also einstückig, so wird das Montieren des Notlaufringes durch die im Durchmesser vergLeichsweise großen Felgenhörner erschwert oder gar unmöglich gemacht.There is a difficulty in making these vehicle wheels i the assembly of the emergency running ring; if the rim is undivided, i.e. in one piece, then the assembly of the emergency ring due to the comparatively large diameter Rim horns made difficult or even impossible.

Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, die eingangs genannten Fahrzeugräder so auszubilden, daß der eigentliche Notlaufring als kompakter, fester Körper ausgeführt, aber dennoch eine Montage auch bei einteiliger Felge ohne weiteres vollzogen werden kann.The invention is essentially based on the object to design the vehicle wheels mentioned so that the actual emergency ring as a compact, Solid body, but still an assembly even with a one-piece rim without further can be carried out.

Zur Lösung dieser Aufrrbe st arfindungsgemäß dpr lnnendurchmesser des Notlaufringes nicht oder nicht wesentlich kleiner als der Außendurchmesser der Falgenkörner der Fadfelge, und zwischen dem Notlaufring und der Radfeige ist ein die Radfelge von außen und den Notlaufring am inneren Durchmesser berufschlagender Blähkörper vorgesehen.To solve this problem, according to the invention, an internal diameter is required of the emergency ring not or not significantly smaller than the outer diameter of the False grains of the thread rim, and between the emergency running ring and the wheel fig is a the outside of the wheel rim and the emergency ring on the inner diameter are more impactful Inflatable body provided.

Der eigentliche, zur Lastaufnahme vorgesehene Notlaufring wird also so ausgeführt, daß er praktisch ohne Behinderung durch die Felgenhörner montiert werden kann, während seine Abstützung gegenüber der Felge durch einen im Durchmesser veränderbaren Blähkörper erfolgt, der zudem noch den Vorteil mit sich bringt, daß im Notlauffall eine elastisch nachgiebige Abstützung stattfindet.The actual emergency ring intended to take up the load is therefore designed so that it can be mounted with practically no obstruction by the rim horns can be, while its support against the rim by one in diameter changeable inflatable body takes place, which also has the advantage that an elastically flexible support takes place in an emergency.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel dargestellt ist.Further details of the invention are explained with reference to the drawing, in which an embodiment is shown.

Die Abb. zeigt einen radialen Teilschnitt durch ein Fahrzeugrad. The illustration shows a partial radial section through a vehicle wheel.

Der elastisch verformbare, im wesentlichen aus Gummi oder gummiähnlichen Stoffen bestehende Luftreifen 1 ist auf einer starren Felge 2 mit Tiefbett 3 montiert.The elastically deformable, essentially made of rubber or rubber-like Pneumatic tires 1 made of materials are mounted on a rigid rim 2 with a drop center 3.

Innerhalb den Reifenhohlrauman 4 befindet sich ein Notlaufring 5 zur Abstitzurig der Zenitpartie 6 des Luftreifens 1, wenn dieser z.B. durch eine Perforation beschädigt worden iet.Inside the tire cavity at 4 there is an emergency running ring 5 for The zenith part 6 of the pneumatic tire 1 is spaced apart if it is, for example, through a perforation has been damaged.

Der Notlaufring 5 besteht nus Schaumstoff oder einem ähnlichen Werkstoff, der in der Lage ist, den Notlaufbetrieb sicherstellen. Er hat einen etwa elliptischen Querschnitt und berührt seitlich bei 7 nahe oberhalb der Felgenhörner 8 die Innenfläche des Reifenkörpers 1. Sein Innendurchmesser D ist geringfügig größer als der durch die Felgenhörner 8 bestimmte Durchmesser d, so daß der Notlaufring 5 ohne weiteres bei der Montage des Reifens 1 in die Betriebsstellung nach der Zeichnung bewegt werden kann.The emergency ring 5 consists of foam or a similar material, who is able to ensure emergency operation. It has a roughly elliptical shape Cross-section and touches the inner surface laterally at 7 close to the rim horns 8 of the tire body 1. Its inner diameter D is slightly larger than that through the rim horns 8 certain diameter d, so that the emergency ring 5 easily during the assembly of the tire 1 moved into the operating position according to the drawing can be.

Damit jedoch der Notlaufring 5 eine ausreichend gute Abstützung erfährt, ist ein ringförmiger Blähkörper 9 aus Gummi oder dergl. vorgesehen, der infolge seiner Verformbarkeit ohne weiteres in das Tiefbett 3 eingelegt werden kann.However, so that the emergency ring 5 experiences a sufficiently good support, An annular inflatable body 9 made of rubber or the like. Is provided, which as a result its deformability can easily be inserted into the deep bed 3.

Der als ringförmiger, dehnbarer Schlauch ausgeführte Blähkörper 9 hat ein Luftventil 10, das durch die Felge 2 geführt bedient und von außen ###### weden kann. Haben der Luftreifen 1 und der Notlaufring 5 die Stellung gemäß Zeichnung erreicht, so wird der Blähkörper 9 unter Innendruck gesetzt, so daß dann der Notlaufring 5 von innen her beaufschlagt wird. Diese Stützung ist bei entsprechend großem Innendruck des Blähkörpers 9 ausreichend, um den Notlaufriiig 5 auch denn ausreichend sicher von innen abzustützen, wenn vergleichsweise große Kräfte von dem Notlaufring 5 auf die Felge 2 übertragen werden müssen.The inflatable body 9 designed as an annular, expandable tube has an air valve 10, which is operated through the rim 2 and from the outside ###### can weden. Have the pneumatic tires 1 and the run-flat ring 5 the position shown in the drawing reached, the inflatable body 9 is placed under internal pressure, so that then the Emergency ring 5 is acted upon from the inside. This support is appropriate for large internal pressure of the inflatable body 9 is sufficient to the Notlaufriiig 5 also because to be supported sufficiently safely from the inside if comparatively large forces of the emergency ring 5 must be transferred to the rim 2.

Es versteht sich, daß für den Reifenhohlraum 4 ein zweites, nicht näher dargestelltes Ventil an der Felge 2 vorgesehen sein muß.It is understood that for the tire cavity 4 a second, not valve shown in more detail on the rim 2 must be provided.

Der Notlaufring 5 kann vorzugsweise an seinem äußeren Umfang mit Vertiefungen und Profilierungen versehen sein, die u.a.The emergency ring 5 can preferably have depressions on its outer circumference and profiles, which i.a.

auch dem Ziel der Gewichtsersparnis dienen können.can also serve the goal of weight saving.
