As a result, reliable transmission of the driving forces from the rim to the tyre is ensured.

Description

Die Erfindung betrifft ein Fahrzeugrad mit den Merkmalen des Oberbe­ griffes von Anspruch 1.The invention relates to a vehicle wheel with the features of the Oberbe handles of claim 1.

Ein Fahrzeugrad dieser Art ist bekannt, was allerdings druckschriftlich nicht belegbar ist.A vehicle wheel of this type is known, but this is in print is not verifiable.

Bei dieser Radkonstruktion sind die üblicherweise vorgesehenen, die seitlichen Anschläge für die Reifenwülste bildenden Felgenhörner durch an der Felge stirnseitig befestigbare Klemmringe ersetzt, welche die Reifenwülste zwischen sich und Abstützflächen der Felge fest­ klemmen.In this wheel construction, the ones usually provided are those side stops for the rim flanges forming tire beads replaced by clamping rings that can be attached to the front of the rim the tire beads between themselves and support surfaces of the rim firmly jam.

Diese Konstruktion bietet den Vorteil, daß bei Entweichen der Luft sich die Reifenwülste relativ zur Felge nicht axial verlagern können und insbesondere eine kurzfristig durchführbare Reifenmontage möglich ist.This construction has the advantage that when the air escapes the tire beads cannot move axially relative to the rim and in particular a tire assembly that can be carried out at short notice is.

Der Erfindung liegt die Aufgabe zugrunde, solche Fahrzeugräder der­ art zu gestalten, daß bei einfach zu bewerkstelligender Klemmring­ montage eine sichere Übertragung der Antriebskräfte von der Felge auf den Luftreifen gewährleistet ist. The invention has for its object such vehicle wheels art to design that with easy to do clamping ring assemble a safe transmission of the driving forces from the rim is guaranteed on the pneumatic tires.  

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1 solved.

Durch die Anordnung von Erhöhungen und/oder Vertiefungen an dem die Reifenwülste zwischen sich festklemmenden Flächen von Felge und Klemmring wird anstelle einer ausschließlich reibschlüssigen eine formschlüssige Verbindung zwischen diesen Teilen und den Reifenwülsten erzielt, die es gestattet, bei der Montage der Klemmringe die durch sie zu erzeugenden Anpresskräfte verhältnismäßig klein zu halten.By arranging elevations and / or depressions on the Tire beads between the clamping surfaces of the rim and Clamping ring is used instead of an exclusively frictional one positive connection between these parts and the tire beads achieved that allows the assembly of the clamping rings through to keep the contact forces to be generated relatively small.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von Unter­ ansprüchen.Advantageous embodiments of the invention are the subject of sub claims.

In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen, teilweise im Querschnitt dargestellten Fahrzeugrades gezeigt.In the drawing is an embodiment of an inventive Vehicle wheel shown partially in cross section.

Die Felge dieses Fahrzeugrades ist als Ganzes mit 10 bezeichnet. Ihr Felgenmantel 12 ist mit einer Radschüssel 14 einstückig ausgebildet. Mit 16 ist als Ganzes ein auf die Felge 10 aufgezogener, beispiels­ weise schlauchloser Luftreifen bezeichnet, dessen beiden Reifenwülste 18 und 20 in jeweils eine von einer der Felgenstirnseiten aus zu­ gängliche und sich in Felgenachsrichtung erstreckende Ringnut 22 bzw. 24 eingreifen. Die Reifenwülste sind mit einem Wulstkern 26 ausgestattet.The rim of this vehicle wheel is designated as a whole by 10 . Your rim shell 12 is integrally formed with a wheel bowl 14 . With 16 as a whole a mounted on the rim 10 , for example tubeless pneumatic tire is designated, the two tire beads 18 and 20 of which engage in one of one of the rim end faces from common and extending in the axial direction of the annular groove 22 and 24 respectively. The tire beads are equipped with a bead core 26 .

Die beiden Ringnuten weisen eine untere Nutwand 28, eine obere Nut­ wand 30 sowie einen Nutboden 32 auf, der entsprechend der Kontur des ihm zugekehrten Umfangteiles des Reifenwulstes 18 bzw. 20 im Quer­ schnitt konkav gekrümmt ist.The two ring grooves have a lower groove wall 28 , an upper groove wall 30 and a groove bottom 32 , which is concavely curved in cross section in accordance with the contour of the peripheral part of the tire bead 18 or 20 facing it.

Zur Befestigung der Reifenwülste 18, 20 in den Ringnuten 22, 24 dient jeweils ein Klemmring 34, der auf eine zylindrische Felgensitzfläche 36 aufsteckbar ist. A clamping ring 34 , which can be plugged onto a cylindrical rim seat surface 36, is used to fasten the tire beads 18 , 20 in the ring grooves 22 , 24 .

Klemmringe 34 sind mit einem Ringkragen 38 ausgestattet, der im montierten Zustand der Klemmringe 34 teilweise in die betreffende Ringnut 22 bzw. 24 hineinragt, wobei die Außenumfangsfläche jedes Klemmringes 34 an der dem Reifenwulst 18 bzw. 20 zugekehrten Seite einen sich in Richtung Kragenende konisch verjüngenden und den be­ treffenden Reifenwulst 18 bzw. 20 hintergreifenden Umfangsflächen­ teil 40 aufweist.Clamping rings 34 are equipped with an annular collar 38 which, in the assembled state of the clamping rings 34, partially projects into the relevant annular groove 22 or 24 , the outer peripheral surface of each clamping ring 34 on the side facing the tire bead 18 or 20 having a conical taper in the direction of the collar end and the be affected tire bead 18 or 20 engaging circumferential surfaces part 40 .

Die Klemmringe 34 werden in ihrer gezeigten Montagestellung durch einen Sprengring 42 gehalten, der in eine Umfangsnut 44 der Felgen­ sitzfläche 36 einsprengbar ist.The clamping rings 34 are held in their assembly position shown by a snap ring 42 , which seat 36 can be detonated into a circumferential groove 44 of the rims.

Die erläuterte Konstruktion ermöglicht eine einfach durchführbare Reifenmontage bzw. -demontage, wobei die Außenumfangsfläche 45 des Felgenmantels 12 sehr breit und für einen Reifennotlauf ausgebildet sein kann.The construction explained enables tire assembly and disassembly to be carried out easily, the outer circumferential surface 45 of the rim casing 12 being very wide and designed for tire emergency running.

Damit eine absolut rutschfeste Verbindung zwischen Felge 10 und Reifen­ wülsten 18, 20 mit Hilfe der Klemmringe 24 erzielt werden kann, ohne zur Montage der Klemmringe diese unverhältnismäßig stark an die Reifenwülste anpressen zu müssen, sind die Wulstklemmflächen von Felge und/oder Klemmringen mit Erhöhungen und/oder Vertiefungen und vorzugsweise die Reifenwülste 18, 20 mit einem entsprechenden Gegen­ profil ausgestattet. Beim vorliegenden Ausführungsbeispiel bilden diese Erhöhungen und Vertiefungen Verzahnungen, die sowohl in den Nutboden 32 als auch in den konischen Flächenteil 40 der Klemmringe 34 eingeformt sind. Die sich quer zur Umfangsrichtung der Ringnuten 22, 24 erstreckenden Zähne sind mit 46 bezeichnet. Diese Verzahnungen könnten auch an der oberen Nutwand 30 oder lediglich dort bzw. an einer der beiden anderen Flächen von Ringnut und Klemmring vorge­ sehen sein. Desweiteren können die Verzahnungen an diesen Flächen bereichsweise oder durchgehend vorgesehen sein. Sofern an den Reifen­ wülsten 18, 20 zu diesen Verzahnungen komplementäre Verzahnungen angeformt sind, justieren sich die Reifenwülste beim Ineingriffbringen mit den Ringnuten 22, 24 selbsttätig so, daß die Verzahnungen mit­ einander in Eingriff sind. Ebenso werden sich beim Aufschieben der Klemmringe 34 auf die Felgensitzflächen 36 und Anlegen an die Reifen­ wülste 18, 20 zwangsläufig so verdrehen, daß die entsprechenden Ver­ zahnungen miteinander in Eigriff sind.So that an absolutely non-slip connection between rim 10 and tire beads 18 , 20 can be achieved with the aid of the clamping rings 24 , without having to press them disproportionately against the tire beads to mount the clamping rings, the bead clamping surfaces of the rim and / or clamping rings are provided with increases and / or depressions and preferably the tire beads 18 , 20 equipped with a corresponding counter profile. In the present exemplary embodiment, these elevations and depressions form toothings which are formed both in the groove base 32 and in the conical surface part 40 of the clamping rings 34 . The teeth extending transversely to the circumferential direction of the ring grooves 22 , 24 are designated by 46 . These teeth could also be seen on the upper groove wall 30 or only there or on one of the other two surfaces of the ring groove and the clamping ring. Furthermore, the teeth on these surfaces can be provided in areas or continuously. If on the tires beads 18 , 20 complementary teeth are formed on these teeth, the tire beads adjust automatically when engaging with the ring grooves 22 , 24 so that the teeth are in engagement with each other. Likewise, when pushing the clamping rings 34 onto the rim seating surfaces 36 and applying them to the tires, beads 18 , 20 will inevitably rotate so that the corresponding toothings are in engagement with one another.

Die formschlüssige Verbindung von Felge 10 und Reifenwülsten 18, 20 stellt sicher, daß letztere unter der Wirkung der Antriebskräfte innerhalb der Ringnuten in Umfangsrichtung nicht verrutschen können. Damit ist eine verschleißsichere und gasdichte Verbindung von Luft­ reifen 16 und Felge 30 gewährleistet.The positive connection of rim 10 and tire beads 18 , 20 ensures that the latter cannot slip in the circumferential direction under the action of the driving forces within the ring grooves. This ensures a wear-resistant and gas-tight connection of air tires 16 and rim 30 .
