Abstract

Combination tyre for motor vehicles for use in winter having at least one fully integrated, radially arranged countersunk grip belt which is located over a circumferential air chamber and can be moved into the tread area of the tyre. The grip belt which is moved out for the purpose of providing the tyre with better grip and is equipped with spikes or similar means moves back into its countersunk position by the medium being let out, as a result of which the status of a spike tyre is cancelled out and the vehicle equipped with combination tyres can be driven again more quickly than at 50 km/h.

Description

Die Erfindung betrifft einen Kraftfahrzeugreifen, der sowohl auf glatten, als auch auf normal beschaffenen Fahrbahnen zum Einsatz kommen kann.The invention relates to a motor vehicle tire that both on smooth, as well as on normal roads Use can come.

Der Reifen verfügt über mindestens einen versenkt angeordne­ ten Greifgurt, der im Bedarfsfalle durch das Aufpumpen von unter ihm liegenden Luftkammern in den Abrollbereich beför­ dert werden kann, um so die Rutschfestigkeit des Reifens zu erhöhen.The tire has at least one recessed ten gripping belt, which if necessary by inflating air chambers beneath it into the rolling area can be changed in order to increase the skid resistance of the tire increase.

Durch Ablassen des Mediums aus den Luftkammern bildet sich der Greifgurt so weit zurück, daß die darauf befindlichen Greifmittel die Fahrbahn nicht mehr berühren können, d.h., daß das mit diesen Reifen ausgerüstete Fahrzeug wieder mit einer höheren Geschwindigkeit betrieben werden kann, als der Gesetzgeber sie für Gleitschutzeinrichtungen mit Spikes vorschreibt.By draining the medium from the air chambers it forms the gripping belt so far back that the ones on it Gripping means can no longer touch the road, i.e. that the vehicle equipped with these tires again with can be operated at a higher speed than Legislators use them for anti-skid devices with spikes prescribes.

Stand der TechnikState of the art

Bekannt sind Schneeketten und Gleitschutzeinrichtungen ver­ schiedenster Art, die montagemäßig auf die Reifen gebracht werden.Snow chains and anti-skid devices are known various types, which are mounted on the tires will.

Hierbei ist jedoch immer etwas technisches Geschick erfor­ derlich. However, some technical skill is always required such.  

Diese Einrichtungen erfüllen durchaus ihren Zweck und sind auch im Laufe der Zeit weiter verbessert worden, sie sind jedoch nie so optimal, daß über Alternativen und Verbes­ serungen nicht mehr nachgedacht zu werden braucht.These facilities serve their purpose and are also have been improved over time, they are however never so optimal that about alternatives and verbes no longer need to be considered.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, mittels eines von jedem Laien auszuführenden Pumpvorgangs einen Normalreifen in einen Gleitschutzreifen zu verwandeln und auf ebenso leichte Weise (Ablassen des Mediums) diesen Vorgang rück­ gängig zu machen.The invention has for its object by means of a normal tire for every layperson to be pumped to transform into an anti-skid tire and on as well easy way (draining the medium) this process back to make common.

Lösungsolution

Die Aufgabe wurde erfindungsgemäß dadurch gelöst, daß in einen elastischen KFZ-Reifen ein umlaufender Greifgurt versenkt integriert wurde, daß durch Erweiterung einer unter dem Greifgurt liegenden Luftkammer derselbe in den Abrollbereich des Reifens gedrückt werden kann, wobei das Einbringen des Mediums zur Erweiterung der Luftkammer über eine gut zugängliche Leitung erfolgt. The object was achieved in that in an elastic car tire an all-round gripping belt sunk was integrated that by expanding a air chamber lying under the gripping belt in the same Rolling area of the tire can be pressed, the Introduce the medium to expand the air chamber there is an easily accessible line.  

Weitere AusgestaltungFurther configuration

Der zugrunde liegende Kombireifen soll in der Hauptsache wäh­ rend der winterlichen Jahreszeit Verwendung finden. Er soll den vorherrschenden Witterungsverhältnissen durch das Aus- und Einfahren des Greifgurts sekundenschnell und kinderleicht angepaßt werden können.The underlying combination tire should mainly be used be used during the winter season. He should the prevailing weather conditions due to the and retracting the gripping belt in seconds and child's play can be adjusted.

Als Medium zur Erweiterung der Luftkammern soll in erster Linie Luft infrage kommen. Mittels einer Hand-oder Fußluftpumpe ist die Luft ohne Schwierigkeiten in die Luftkammern einzubringen. Sie ist durch kurzes Antippen eines Rückschlagventils ebenso wieder ablaßbar.First and foremost, as a medium for expanding the air chambers Air. Using a hand or foot air pump to bring the air into the air chambers without difficulty. It is the same by briefly tapping a check valve drainable again.

Der Kombireifen könnte (ähnlich den heute verwendeten Winter­ reifen) als Zusatzreifen Verwendung finden.The combination tire could (similar to the winter used today tires) can be used as additional tires.

In der Zeichnung ist die Erfindung an einem Ausführungsbei­ spiel veranschaulicht. Es zeigen:In the drawing, the invention is in one embodiment game illustrated. Show it:

Fig. 1 und Fig. 2 jeweils einen Schnitt durch den Kombirei­ fen. Fig. 1 and Fig. 2 each have a section through the Kombirei fen.

Sowohl in Fig. 1 als auch in Fig. 2 befinden sich die Greif­ gurte (3) in ihrer versenkten Lage.Both in Fig. 1 and in Fig. 2, the gripping straps ( 3 ) are in their lowered position.

In Fig. 1 ist eine Ausführung mit einer separat eingebrachten Luftkammer (1) zu sehen.In Fig. 1 an embodiment with a separately introduced air chamber ( 1 ) can be seen.

In Fig. 2 ist die Luftkammer (2) organisch in den Reifen (9) eingearbeitet. In Fig. 2 the air chamber ( 2 ) is incorporated organically in the tire ( 9 ).

Die Greifgurte (3) werden in beiden Darstellungen durch um­ laufende elastische Haltelippen (6) in ihrer versenkten Lage gehalten.The gripping belts ( 3 ) are held in their lowered position in both representations by elastic retaining lips ( 6 ).

Die in den Beschreibungen und in den Patentansprüchen nieder­ gelegten sowie in den Zeichnungen dargestellten Merkmale kön­ nen sowohl einzeln als auch in beliebigen Kombinationen für die Verwirklichung der Erfindung wesentlich sein.That is reflected in the descriptions and in the claims characteristics as well as shown in the drawings NEN individually as well as in any combination for the realization of the invention may be essential.
