Description

Die Erfindung betrifft ein Sicherheitsfahrzeugrad wie es im Oberbegriff von Anspruch 1 gekennzeichnet ist.The invention relates to a safety vehicle wheel as it is characterized in the preamble of claim 1.

Durch die DE-OS-2851187 ist ein Notlaufring für Fahrzeug- Luftreifen bekannt geworden, welcher auf eine Flachbett­ felge montiert zusammen mit einem schlauchlosen Luftreifen ein Sicherheitsfahrzeugrad bilden. Der Innenumfang des Notlaufringes ist auf den Felgengrund aufgeschoben. Im Notlaufbetrieb, wenn bei Luftverlust die Reifeninnenwand am Aussendurchmesser des Notlaufringes aufliegt, besteht die Gefahr, dass der Reifen und der Notlaufring rutscht und sich gegenüber dem Felgengrund verdreht, was zu so­ fortigem Drehmoment-Verlust führt. Besonders anfällig sind Einheiten, die über wenig seitliche Pressung ver­ fügen.DE-OS-2851187 is an emergency running ring for vehicle Pneumatic tires become known on a flat bed rim assembled together with a tubeless pneumatic tire form a safety vehicle wheel. The inner circumference of the Run-flat ring is pushed onto the rim base. in the Run-flat operation if the inner wall of the tire is lost rests on the outside diameter of the emergency ring the risk of the tire and the run-flat ring slipping and twisted towards the bottom of the rim, which leads to this continued loss of torque. Particularly vulnerable are units that have little lateral pressure put.

Aufgabe der vorliegenden Erfindung ist es, die Felge und den Notlaufring so auszubilden, dass ein Rutschen bzw. Verdrehen des Notlaufringes nicht möglich ist. The object of the present invention is the rim and design the run-flat ring so that slipping or Rotation of the emergency ring is not possible.  

Erfindungsgemäss wird dies durch die kennzeichnenden Merk­ male von Anspruch 1 gelöst.According to the invention, this is achieved by the characterizing note male solved by claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Further advantageous embodiments of the invention are in characterized in the dependent claims.

Die Erfindung ist in den beiliegenden Zeichnungen darge­ stellt und nachfolgend beschrieben.The invention is illustrated in the accompanying drawings represents and described below.

Es zeigen:Show it:

Fig. 1 einen Querschnitt durch eine Schrägschulter­ felge mit verschraubtem Schrägschulter-Seiten­ ring und mit Notlaufring und Luftreifen, Fig. 1 shows a cross section through a taper rim with screw-helical shoulder pages ring and emergency rim and pneumatic tire,

Fig. 2 einen Querschnitt durch eine Schrägschulter­ felge mit Seiten- und Verschlussring und Fig. 2 shows a cross section through an oblique shoulder rim with side and locking ring and

Fig. 3 einen Teillängsschnitt III-III von Fig. 1. Fig. 3 is a partial longitudinal section III-III of Fig. 1,.

Das Sicherheitsfahrzeugrad gemäss Fig. 1 und 3 besteht aus einer Schrägschulterfelge 1 mit einem verschraubten Schräg­ schulter-Seitenring 2, einem schlauchlosen Luftreifen 3 und einem in dem Luftreifen 3 auf dem Felgengrund 4 ange­ ordneten Notlaufring 5, welcher vorzugsweise aus Gummi oder einem anderen Elastomer besteht.The Sicherheitsfahrzeugrad according to FIGS. 1 and 3 consists of a taper rim 1 with a screwed oblique shoulder-side ring 2, a tubeless pneumatic tire 3 and a is in the pneumatic tire 3 on the wheel base 4 associated emergency rim 5 which is preferably made of rubber or other elastomer .

Die Felge 1 weist am Felgengrund 4 gleichmässig am Umfang verteilte Vertiefungen 6 auf, welche an den Uebergängen zum Felgengrund 4 mit Radien 7 versehen sind, so dass der Felgengrund im Querschnitt annähernd wellenförmig ausge­ bildet ist. Die Grundfläche 8 der Vertiefungen 6 liegt auf einem Durchmesser, welcher dem Zentrierdurchmesser 9 des anschraubbaren Seitenringes 2 entspricht. Ausgehend von diesem Zentrierdurchmesser 9 erstrecken sich die Ver­ tiefungen 6 in Richtung der Radachse bis zu einer schräg nach aussen verlaufenden Endbegrenzungsfläche 10, wobei der Notlaufring mit seinen Vorsprüngen 11 bis zu der Endbegrenzungsfläche 10 einschiebbar ist. Die Vertiefungen 6 bilden zusammen mit den Vorsprüngen 11 des Notlaufringes 5 eine Verdrehsicherung zwischen Felge und Notlaufring. Dadurch wird verhindert, dass auch wenn der Luftreifen 3 auf dem Notlaufring 5 aufliegt und das Fahrzeugrad weiter fährt, Reifen und Notlaufring sich gegenüber dem Felgen­ rad nicht verdrehen können, wodurch Reibungen und Beschä­ digungen dieser Teile verhindert werden.The rim 1 has on the rim base 4 evenly distributed on the periphery depressions 6 , which are provided at the transitions to the rim base 4 with radii 7 , so that the rim base is approximately wavy in cross section. The base area 8 of the depressions 6 lies on a diameter which corresponds to the centering diameter 9 of the screwable side ring 2 . Proceeding from this centering diameter 9 , the recesses 6 extend in the direction of the wheel axis up to an obliquely outwardly extending end boundary surface 10 , the emergency running ring with its projections 11 being insertable up to the end boundary surface 10 . The depressions 6 together with the projections 11 of the run-flat ring 5 form an anti-rotation device between the rim and the run-flat ring. This prevents that even if the pneumatic tire 3 rests on the run-flat ring 5 and the vehicle wheel continues to drive, the tire and run-flat ring cannot turn against the wheel rim, thereby preventing friction and damage to these parts.

Fig. 2 zeigt eine Ausführungsvariante einer Schrägschulter­ felge 1 mit einem zweiteiligen Schrägschulter-Seitenring 2, welcher aus einem Verschlussring 2 a und einem Seitenring 2 b besteht. Der Verschlussring 2 a ist mittels einer form­ schlüssigen Schnappverbindung in der Felge 1 gehalten und entsprechend Fig. 1 auf dessen Zentrierdurchmesser 9 zen­ triert. Die Ausbildung des Notlaufringes 5 und des Felgen­ grundes 4 mit den Vorsprüngen 11 und den Vertiefungen 6 mit der Grundfläche 8 entsprechen der zu Fig. 1 beschrie­ benen Ausführung. Fig. 2 shows a variant of an inclined shoulder rim 1 with a two-part inclined shoulder side ring 2 , which consists of a locking ring 2 a and a side ring 2 b . The locking ring 2 a is held by means of a positive snap connection in the rim 1 and zen trated according to FIG. 1 on the centering diameter 9 . The formation of the emergency ring 5 and the rim base 4 with the projections 11 and the depressions 6 with the base 8 correspond to the embodiment described to FIG. 1.

Vorzugsweise wird diese Verdrehsicherung bei gegossenen Felgenrädern verwendet, wobei die Vertiefungen im Giess­ verfahren hergestellt werden. Die Felgen können auch im Walz- oder Schmiedeverfahren hergestellt werden.This anti-rotation device is preferably cast Rim wheels used, the recesses in the casting processes are produced. The rims can also in Rolling or forging processes are produced.

Derartige Sicherheitsfahrzeugräder, bestehend aus einer Luftreifen-Notlaufring-Felgen-Kombination werden vorwie­ gend bei Militär-, Feuerwehr- und Polizeifahrzeugen verwendet.Such safety vehicle wheels, consisting of a Pneumatic tire runway rim-combination are as before used in military, fire and police vehicles.
