Abstract

The safety wheel rim has a ring shaped reservoir (3) under the rim to hold a supply of high pressure air which can replenish air losses in the tyre via a pressure control valve (6). The reservoir and the tyre are filled by separate valves (7, 8) leading to the outside. The system ensures that air losses are compensated for either automatically or by remote control, in response to pressure monitors. It enables a driver to drive to a service centre with a slowly leaking tyre.

Description

Felge für schlauchlosen LuftreifenRim for tubeless pneumatic tires

Die Erfindung betrifft eine Felge für einen schlauchlosen Luftreifen, insbesondere bei Kraftfahrzeugen und Flugzeugen.The invention relates to a rim for a tubeless pneumatic tire, especially in automobiles and airplanes.

Bei den bekannten Reifen ist es erforderlich, in regelmässigen Abständen den Luftdruck im Reifen zu überprüfen, da insbesondere ein zu niedriger Luftdruck im Reifen nachteilige Folgen mit sich bringen kann. Zur Behebung dieses Nachteils liegt der Erfindung die Aufgabe zugrunde, eine möglichst einfache Einrichtung zu schaffen, mittels derer erreicht wird, daß der Luftreifen stets den vorgeschriebenen Mindestluftdruck aufweist.With the known tires, it is necessary at regular intervals Check the air pressure in the tire, especially because the air pressure is too low can have adverse consequences in the tire. To remedy this disadvantage the invention is based on the object of providing a device that is as simple as possible create, by means of which it is achieved that the pneumatic tire always the prescribed Has minimum air pressure.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Felge einen dicht abgeschlossenen Ringraum aufweist, der über ein Druckminderventil mit dem Reifeninnenraum verbunden ist, und der Reifeninnenraum und der Ringraum über gesonderte Ventile mit der Außenluft in Verbindung stehen.To solve this problem, the invention provides that the Rim has a tightly sealed annular space, which is via a pressure reducing valve is connected to the tire interior, and the tire interior and the annulus are in contact with the outside air via separate valves.

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist derart, daß dem Ringraum ein größerer Überdruck aufgegeben wird, als der Normaldruck im Reifeninneren beträgt.The operation of the device according to the invention is such that the annulus is given a greater overpressure than the normal pressure inside the tire amounts to.

Durch die Wirkung des Druckminderventils wird erreicht, daß der Ausgangsdruck, der sich in diesem Fall auf der dem Reifeninnenraum entsprechenden Seite des Ventils befindet, immer auf einem bestimmten Maß gehalten wird, und zwar auf demaenigen Maß, welches dem Mindestflnnendruck des Luftreifens entspricht. Wenn der Druck im Reifeninnenraum aus irgendeinem Grunde langsam nachläßt, strömt Druckluft aus dem Ringraum nach und hält somit den Druck konstant.The effect of the pressure reducing valve ensures that the outlet pressure, which in this case is on the side of the valve corresponding to the tire interior is, is always kept to a certain level, namely on demaenigen Measure which corresponds to the minimum internal pressure of the pneumatic tire. If the pressure is in If the tire interior is slowly decreasing for some reason, compressed air will flow out of the Annulus and thus keeps the pressure constant.

Wenn der Ringraum nicht mit Druck beaufschlagt ist, so bleibt die Verbindung zwischen Reifeninnenraum und Ringraum das Druckminderventil geschlossen, derart, daß auch herkömmlicher Betrieb der Vorrichtung, also ohne Einsatz des zusätzlichen Ringraums, möglich ist.If the annulus is not pressurized, it remains Connection between tire interior and annulus, the pressure reducing valve is closed, such that even conventional operation of the device, without using the additional Annular space, is possible.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß der Ansprechdruck des Druckminderventils einstellbar ist.According to a further feature of the invention it can be provided that the response pressure of the pressure reducing valve is adjustable.

In zweckmäßiger Ausgestaltung der Erfindung kann weiterhin vorgesehen sein, daß das Druckminderventil ein mechanisch arbeitendes Druckminderventil ist.In an expedient embodiment of the invention, provision can also be made be that the pressure reducing valve is a mechanical pressure reducing valve.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß das Druckininderventil fernsteuerbar ist. Die Fernsteuerung des Druckminderventils erfolgt dabei vorzugsweise auf elektronische Weise.According to a further feature of the invention it can be provided that the pressure reducing valve can be remotely controlled. The remote control of the pressure reducing valve is preferably done electronically.

Nach einem weiteren Merkmal der Erfindung kann eine Anzeigeeinrichtung zum Ablesen der Druckwerte in dem Reifeninnenraum und/oder dem Ringraum vorgesehen sein. Eine solche Anzeigeeinrichtung kann beispielsweise ortsfest am Armaturenbrett angebracht und über geeignete Ubertragungseinrichtungen mit den Rädern in Verbindung stehen.According to a further feature of the invention, a display device provided for reading the pressure values in the tire interior and / or the annulus be. Such a display device can, for example, be stationary on the dashboard attached and connected to the wheels via suitable transmission devices stand.

Die Erfindung wird nachfolgend anhand des in der Zeichnung schematisch dargestellten AusfUhrungsbeispiels näher erläutert. Die Figur zeigt einen schematischen Querschnitt durch einen Luftreifen mit einem Abschnitt einer Felge.The invention is illustrated schematically below with reference to the in the drawing illustrated AusfUhrungsbeispiels explained in more detail. The figure shows a schematic Cross section through a pneumatic tire with a section of a rim.

Ein schlauchloser Luftreifen 1 ist auf einer Felge 2 montiert. Die Felge 2 weist einen dicht nach außen hin abgeschlossenen Ringraum 3 auf, welcher in einer Zwischenwand 4 zu dem Reifeninnenraum 5 ein Druckminderventil 6 aufweist.A tubeless pneumatic tire 1 is mounted on a rim 2. the Rim 2 has an annular space 3 which is sealed off towards the outside and which has a pressure reducing valve 6 in an intermediate wall 4 to the tire interior 5.

Dieses Druckminderventil 6 ist derart ausgebildet, daß der Druck im Reifeninnenraum 5 stets auf einem bestimmten Mindestmaß gehalten wird, indem Druckluft aus dem Ringraum 3 bei einem Druckabfall in dem Reifeninnenraum 5 in diesen nachströmt. Wenn andererseits der Druck im Reifeninnenraum 5 größer als der Druck im Ringraum 3 ist, so bleibt das Druckminderventil 6 geschlossen. Zur Füllung des Ringraums 3 ist ein schematisch dargestelltes Ventil 7 vorgesehen.This pressure reducing valve 6 is designed such that the pressure in Tire interior 5 is always kept to a certain minimum by compressed air from the annulus 3 in the event of a pressure drop in the tire interior 5 flows into this. On the other hand, when the pressure in the tire interior 5 is greater when the pressure is in the annular space 3, the pressure reducing valve 6 remains closed. A valve 7, shown schematically, is provided for filling the annular space 3.

Zum Füllen des Reifeninnenraums 5 bzw. Druckablassen aus dem Reifeninnenraum 5 ist ein weiteres Ventil 8 vorgesehen, welches über eine Leitung 9 direkt vom Reifeninnenraum 5 durch den Ringraum 3 nach außen geführt ist.For filling the tire interior 5 or releasing pressure from the tire interior 5 another valve 8 is provided, which via a line 9 directly from the tire interior 5 is passed through the annular space 3 to the outside.
