Abstract

The wheel rim has different diameters of wheel rim and a central groove between the rims. A variable diameter ring is fitted into the central groove and has its outer diameter larger than the diameter of the smaller wheel rim and smaller than the diameter of the larger wheel rim. It prevents the smaller diameter tyre wall from sliding off the rim, and has its adjacent side to the smaller wheel rim inclined to retain the tyre. The ring is trapezoidal and is positioned so as not to hinder the axial movement of the larger tyre wall for tyre changing.

FahrzeugradVehicle wheel

Die Erfindung betrifft ein Fahraeugrad mit einem auf einer Tiefbettfelge nr.geordneten Luftreifen, dessen Wülste unterschiedliche Durchmesser haben, und es liegt ihr die Aufgabe zugrunde, diese Fahrzeugräder co zu verbessern, daß ein Reifenwulst unter Verwendung einfacher technischer Mittel wirkungsvoll gegen Abdrücken von der'Sitzfläche gesichert wird.The invention relates to a Fahraeugrad with a nr.geordneten on a drop rim tires whose beads have different diameters, and has as its object to improve this vehicle wheels co that a tire using simple technical means effective against imprints of der'Sitzfläche is secured.

Zur Lösung dieser Aufgabe ist erfindungsgemäß im Tiefbett der Felge ein die Felge umschließender Rinj angeordnet, dessen Außendurchmesser größer ist als der Innendurchmesser des im Durchmesser kleineren I?eifenv.'ulstes. Dieser kleinere Reifenwulst ist nunmehr somit zwischen dem iir. Tiefbett angeordneten Sing einerseits und dem Felgenhorn der Felge ε-ndererseits angeordnet. So wird ein ungewolltes Abrutschen der Wulstpartie von seiner Sitzfläche verhindert. Dieser auswechselbare Ring führt im übrigen nicht zu einer Behinderung der Reifennontage bzw. Reifendemontage. Dies ist insbesondere dann der Fall, wenn der Außendurchmesser des eingelegten Ringes wiederum kleiner ist als der Durchmesser des größeren Reifenwulstes bzw. der Durchmesser der zugehörigen Felgensitzflache.To solve this problem, according to the invention, the rim is in the drop center arranged a Rinj surrounding the rim, the outer diameter of which is larger than the inner diameter of the inner diameter of the outer rim, which is smaller in diameter. This smaller tire bead is now between the iir. Deep bed arranged sing on the one hand and the rim flange of the Rim ε-on the other hand arranged. This prevents the Prevented bulge from its seat. In addition, this replaceable ring does not impede tire installation or tire removal. This is especially the case when the The outer diameter of the inserted ring is in turn smaller than the diameter of the larger tire bead or the diameter of the associated rim seat.

V/eitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel dargestellt ist. Die Abbildung zeigt einen radialen Teilschnitt durch ein Fahrzeugrad.Further details of the invention are explained with reference to the drawing, in which an embodiment is shown. The figure shows a partial radial section through a vehicle wheel.

Die in bekannter Weise aus Stahl oder dergl. bestehende Felge 1 hat ein Tiefbett 2 in Form einer umlaufenden etwa trapezförmigen Nut und zu beiden Seiten hiervon konisch ansteigende Sitzflächen 3> ^i an denen sich die Felgenhörner 5» 6 als seitlicher Abschluß anschließen. Der für diese Felge vorgesehene Luftreifen 7 hat Wulstpartien 8 und mit hierin befindlichen V/ulstkernen 10 zur Verankerung der nicht näher dargestellten Karkasse. Die Wülste 8, 9 haben unterschiedliche Durch-The rim 1, which is made of steel or the like in a known manner, has a deep bed 2 in the form of a circumferential approximately trapezoidal groove and on both sides of this conically rising seat surfaces 3> ^ i to which the rim horns 5 »6 adjoin as a side closure. The pneumatic tire 7 provided for this rim has bead parts 8 and with V / ulstkernen 10 located therein for anchoring the not in detail illustrated carcass. The beads 8, 9 have different diameters

nesser den Felgensitzflächen 3 und h entsprechend. Der kleinere Durchmesser der Sitzfläche 3 bzw. des Uulstes 9 ist mit D1 und der größere Durchmesser des Wulstes 8 bzv/. der zugehörigen Sitzfläche h ist mit D2 bezeichnet.the rim seat surfaces 3 and h accordingly. The smaller diameter of the seat 3 or of the bulge 9 is D1 and the larger diameter of the bulge 8 or v /. the associated seat surface h is denoted by D2.

In das Tiefbett 2 isl ein aus Gummi oder gumrniähnlichen Stoffen bestehender gegebenenfalls nach Art eines Keilriemens aufgebauter endloser Ring 11 eingelegt, der die Felge -1 umschließt. Der Außendurchmesser Da des Ringes 11 ist größer als der Durchmesser D1, hir.gegeji kleiner als der Durchmesser D2. Dadurch wird erreicht, daß durch den Ring 11 eine Bewegung des Wulstes 8 in die Stellung bei a nicht behindert wird, hingegen ein Abrutschen des Wulstes 9 in Richtung auf das Felgenbett 11 nicht eintreten kann. Dadurch wird eine Lagesicherung des l/ulstes 9 hergestellt.In the deep bed 2 is made of rubber or rubber-like materials optionally constructed in the manner of a V-belt, endless Ring 11 inserted, which surrounds the rim -1. The outside diameter Da of the ring 11 is larger than the diameter D1, hir.gegeji smaller than the diameter D2. This ensures that a movement of the bead 8 into the position at a is not hindered by the ring 11, on the other hand, the bead 9 cannot slip in the direction of the rim base 11. This secures the position of the l / ulstes 9 manufactured.

Besonders zweckmäßig ist dabei die in Richtung auf der. Wulst 9 vorspringende Nase 12 des Ringes 11, die eine hinterscl.nittene Anschlagfläche 13 für den Wulst 9 umschließt.It is particularly useful in the direction of the. Bead 9 protruding Nose 12 of the ring 11, which has a rear-cut stop surface 13 for the bead 9 encloses.

Das Rad wird so montiert, daß der Durchmesser D1 an der Fahrzeugaußenseite angeordnet werden kann. Damit wird der hier befindliche Teil des Reifens, insbesondere der Reifenwulst 9 gegen Abdrücken von seiner Sitzfläche 3 gesichert, während der Reifenwulst 8 ohnehin nicht von der Felge ablaufen kann.The wheel is mounted so that the diameter D1 is on the outside of the vehicle can be arranged. The part of the tire located here, in particular the tire bead 9, is thus prevented from being pushed off secured by its seat 3, while the tire bead 8 can not run off the rim anyway.

Zur Kontage des Reifens wird zunächst der Reifenwulst 8 auf die Felge 1 aufgeschoben, dann aufgrund des Tiefbettes 2 der Reifenwulst 9· Der Reifen wird nunmehr mit Luft gefüllt, damit die Wülste 8, 9 auf ihre Sitzflächen 3t ^ gleiten. Anschließend v/ird der Reifen drucklos gemacht und der Wulst 8 von seiner Sitzfläche k abgedrückt, worauf dann der elastische, im Durchmesser veränderbare Ring 11 in das Felgenbett 2 eingelegt v/erden kann. Zur Demontage drs Reifens wird 4iecer drucklos^emacht, worauf dann der Reifenwulst 8 in die Stellung bei a bewegt und dann der Ring 11· entfernt werden kann, wodurch dann wiederum eine Demontage des Wulstes 9 herbeigeführt v/erden kann.To contact the tire, first the tire bead 8 is pushed onto the rim 1, then due to the drop center 2 the tire bead 9 · The tire is now filled with air so that the beads 8, 9 slide onto their seat surfaces 3t ^. The tire is then depressurized and the bead 8 is pressed off its seat surface k , whereupon the elastic ring 11, which can be changed in diameter, can be inserted into the rim base 2. To dismantle the tire, the pressure is released, whereupon the tire bead 8 is moved into the position at a and the ring 11 can then be removed, which in turn can cause the bead 9 to be dismantled.
