Abstract

In a safety rim with an emergency tyre and automatic compressed air filling system, the rim has additional projections (8) for accommodating the emergency tyre (3) and has a cavity for receiving compressed air. The cavity stretches over the entire circumference or it can consist of one or several segments. The cavity and the space between the rim-bed and the tyre are connected with each other by holes.

Description

Es sind Erfindungen bekannt, durch die es möglich ist, während der Fahrt den Luftdruck im Reifen zu messen und mit Hilfe von Anzeigeinstrumenten im Cockpit des Fahrzeugs anzuzeigen.Inventions are known by which it is possible during the Drive to measure the air pressure in the tire and with the help of Display instruments in the cockpit of the vehicle.

Dies wird erreicht, indem im Felgenbett des Reifens ein Druck­ sensor angebracht ist der den Reifendruck mißt und die Meßergeb­ nisse an das Anzeigegerät weiterleitet.This is achieved by applying pressure in the rim well of the tire sensor is attached which measures the tire pressure and the measurement result forwards to the display device.

Dabei ist es allerdings nicht möglich, auf den Luftdruck im Reifen einzuwirken, d. h. den Luftdruck zu regulieren bzw. bei Druckverlust wieder zu normalisieren.However, it is not possible to check the air pressure in the To act on tires, d. H. regulate the air pressure or at Normalize pressure loss again.

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zu­ grunde, während der Fahrt bei Druckverlust den Verlust auszu­ gleichen und bei schwerer Beschädigung des Reifens das Fahrzeug spurstabil zum Halten zu bringen.The invention specified in claim 1 addresses the problem reasons to compensate for the loss of pressure loss while driving same and if the tire is severely damaged the vehicle to keep track stable.

Die Vorteile der Erfindung bestehen darin, daß während der Fahrt der Luftdruck im Reifen immer konstant gehalten werden kann. Desweiteren wird es ermöglicht, bei Reifenbeschädigung mit dem im inneren angebrachten Notlaufreifen weiterfahren bzw. das Fahrzeug sicher und spurstabil zum stehen zu bringen. Weiterhin handelt es sich um ein in sich geschlossenes System, es sind keine Verbindungen, Leitungen usw. zum Fahrzeug erforder­ lich.The advantages of the invention are that while driving the air pressure in the tire can always be kept constant. Furthermore, it is possible to use the continue inside the run-flat tire or the Bring the vehicle to a safe and stable stop. Furthermore, it is a self-contained system, no connections, lines, etc. to the vehicle are required Lich.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment is shown in the drawing and is described in more detail below.

Das Felgenbett der Sicherheitsfelge (1) ist so gestaltet, daß außen ein handelsüblicher Reifen (2) und im inneren durch zusätzliche Erhebungen (8) ein Notlaufreifen (3) aufgenommen werden kann. The rim base of the safety rim ( 1 ) is designed in such a way that a commercially available tire ( 2 ) can be picked up on the outside and a run-flat tire ( 3 ) can be picked up on the inside by additional elevations ( 8 ).

Weiterhin ist unterhalb des Felgenbettes ein Hohlraum (7) der sich über den gesamten Umfang erstrecken kann angeordnet, der als Lufthochdruckkammer dient.Furthermore, a cavity ( 7 ), which can extend over the entire circumference and is used as a high-pressure air chamber, is arranged below the rim well.

Die Felge enthält zwei Verbindungsbohrungen, die die Hochdruckkammer mit dem Raum unterhalb des Reifens (2) verbinden und eine Bohrung die nach außen führt, in der das Lufteinfüllventil (4) für die Hochdruckkammer sitzt. In der Bohrung unterhalb des Notlaufreifens (2) sitzt ein Ventil (5) zum befüllen des selben bei plötzlichem Druckverlust im Reifen (2).The rim contains two connecting holes that connect the high pressure chamber to the space below the tire ( 2 ) and a hole that leads to the outside, in which the air fill valve ( 4 ) for the high pressure chamber is located. In the hole below the run-flat tire ( 2 ) there is a valve ( 5 ) for filling the same in the event of a sudden loss of pressure in the tire ( 2 ).

In der anderen Verbindungsbohrung befindet sich das Ventil (6) durch welches es ermöglicht wird, Luft von der Hochdruckkammer (7) in den Reifen (2) überströmen zu lassen.The valve ( 6 ) is located in the other connecting bore, which enables air to flow from the high-pressure chamber ( 7 ) into the tire ( 2 ).

WirkungsweiseMode of action

Treten während der Fahrt Undichtigkeiten im Bereich des Reifens (2) auf, kann der Druckverlust der dann entsteht dadurch ausge­ glichen werden, daß durch das Ventil (6) die Luft aus der Hoch­ druckkammer (7) in den Hohlraum des Reifens (2) überströmt und so der Reifenluftdruck konstant gehalten wird.If leaks occur in the area of the tire ( 2 ) while driving, the pressure loss which then arises can be compensated for by the fact that the valve ( 6 ) overflows the air from the high pressure chamber ( 7 ) into the cavity of the tire ( 2 ) and so the tire air pressure is kept constant.

Wird während der Fahrt der Reifen (2) stark beschädigt öffnet sich durch den plötzlichen Druckverlust im Reifen (2) das Ventil (5), wodurch jetzt schlagartig die Luft von der Hoch­ druckkammer (7) in den Notlaufreifen (3) strömt und diesen aufpumpt.If the tire ( 2 ) is severely damaged during the journey, the sudden loss of pressure in the tire ( 2 ) opens the valve ( 5 ), causing the air from the high-pressure chamber ( 7 ) to suddenly flow into the run-flat tire ( 3 ) and inflate it .

Claims (3)
