Abstract
Description
Die Erfindung betrifft eine Wulstsicherung für Fahrzeugluftreifen; sie hat die Aufgabe, die vorschriftsmäßige Lage der Reifenwülste auf den zugehörigen Felgensitzflachen sicherzustellen, und zwar insbesondere dann, wenn der Reifenhohlraum nicht mehr unter überdruck bzw. unter verringertem Überdruck steht.The invention relates to a bead lock for pneumatic vehicle tires; its task is to ensure the correct position of the tire beads on the associated rim seat surfaces, in particular when the tire cavity is no longer under overpressure or under reduced overpressure.
Es ist bereits bekannt, der Felge eine bestimmte Kontur in der Weise zu verleihen, daß die Zehe der Reifenwülste gegen einen umlaufenden Vorsprung der Felge anstößt, bevor der Reifenwulst seine Sitzfläche verlassen hat. Diese Ausführung setzt eine besondere Gestaltung der Felge voraus. Sie ist zudem in Extremfällen unwirksam, z.B. dann, wenn der Reifenhohlraum nicht mehr unter überdruck steht.It is already known that the rim has a certain contour in this way to give that the toe of the tire beads abuts against a circumferential projection of the rim before the tire bead its seat has left. This version requires a special design of the rim. It is also ineffective in extreme cases, e.g. then when the tire cavity is no longer under overpressure.
Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, eine Wulstsicherung für Luftreifen zu schaffen, die bei geringem Aufwand ein Verlassen der Felgensitzflachen auch dann verhindert, wenn im Reifenhohlraum atmosphärischer Druck herrscht.The invention is essentially based on the object of a bead lock for pneumatic tires that prevent leaving the rim seat surfaces with little effort, even when in the tire cavity atmospheric pressure prevails.
Zur Lösung dieser Aufgabe sind erfindungsgemäß über den Umfang der Felge verteilte einschraubbare Bolzen vorgesehen, die mit ihrem einen Ende die Außenfläche der Felge überragen und mit ihrem anderen Ende in einer außen an der Felge gelagerten Buchse angeordnet sind.To solve this problem are according to the invention beyond the scope of Rim distributed screw-in bolts provided that with their one End beyond the outer surface of the rim and with its other end are arranged in a socket mounted on the outside of the rim.

Zweckmäßigerweise wird dabei die vorzugsweise an die Felge angeschweißte Buchse mit einem Gewinde versehen, damit der Schraubbolzen durch Eindrehen in das Gewinde befestigt werden kann.Appropriately, the preferably welded to the rim Provide the socket with a thread so that the screw bolt can be fastened by screwing it into the thread.
Diese so befestigten Bolzen haben den Vorteil, daß sie zur Montage des Reifens entfernt und nach dessen Montage eingeschraubt werden können, wobei sie beliebig weit in den Reifenhohlraum hineinragen können und dabei eine ausreichend hohe Sperre bilden können, die das Abgleiten des Reifenwulstes verhindert.These bolts fastened in this way have the advantage that they are used for assembly of the tire can be removed and screwed in after its assembly, protruding as far as desired into the tire cavity can and can thereby form a sufficiently high barrier that prevents the tire bead from sliding off.
Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel dargestellt ist. Die Abbildung zeigt einen radialen Teilschnitt durch ein luftbereiftes Fahrzeugrad.Further details of the invention are explained with reference to the drawing, in which an exemplary embodiment is shown. the The figure shows a radial partial section through a vehicle wheel with pneumatic tires.
Die Tiefbettfelge 1 hat eine schwach konisch ansteigende Sitzfläche für den Wulst 3 des Luftreifens *t; der Wulst 3 kann durch einen zugfesten Kern 5 verstärkt sein. Seitlich außen liegen die Reifenwülste 3 am Felgenhorn 6 an.The drop center rim 1 has a slightly conically rising seat surface for the bead 3 of the pneumatic tire * t; the bead 3 can by a tensile core 5 be reinforced. The tire beads are on the outside 3 on the rim flange 6.
Seitlich neben der Sitzfläche 2 befinden sich mehrere über den Umfang der Felge 1 verteilt angeordnete Bohrungen 7· Koaxial hierzu sind außen auf der Felge Metallbuchsen 8 durch Schweißnähte 9 fest angebracht. Die sich dabei ergebende Bohrung ist mit einem Gewinde versehen.Laterally next to the seat surface 2 there are several bores 7, which are distributed over the circumference of the rim 1, and are coaxial with it Metal sockets 8 are firmly attached to the outside of the rim by welds 9. The resulting hole is threaded Mistake.

In dieses Gewinde ist ein Bolzen 10 mit Schraubkopf 11 eingeschraubt, und zwar durch Zwischenlegen einer Dichtungsscheibe 12 luftdicht.A bolt 10 with a screw head 11 is screwed into this thread, by interposing a sealing washer 12 airtight.
Das freie Ende des Bolzens 10 ist abgesetzt, so daß sich ein im Durchmesser kleinerer Stummel 13 ergibt, der den Außendurchmesser der Felge 1 um mehrere Millimeter in der Weise überragt, daß der Stummel ein Abrutschen der !Reifenwülste 3 in Bichtung des Pfeiles *\k ausschaltet.The free end of the bolt 10 is offset, so that a stub 13 with a smaller diameter results, which protrudes over the outer diameter of the rim 1 by several millimeters in such a way that the stub prevents the tire beads 3 from slipping off in the direction of the arrow * \ k turns off.
