Description

Die Erfindung betrifft eine Schnellkupplung umfassend eine am Ende eines medienführenden Hohlbauteils fixierte und an dessen Außenseite anliegende Hülse aus Metall, die mindestens eine Rastnase und am inneren Ende einen Anschlagbund aufweist und eine Nut zur Aufnahme eines Dichtrings begrenzt.The invention relates to a quick coupling comprising a fixed at the end of a media-carrying hollow component and fitting on the outside sleeve of metal, which has at least one locking lug and at the inner end a stop collar and limits a groove for receiving a sealing ring.

Eine bekannte Schnellkupplung dieser Bauart umfaßt eine zusätzliche Hülse, die an der Innenseite des von einem Elastomerschlauch gebildeten Hohlbauteils anliegt. Zur Befestigung an dem Elastomerschlauch wird die innere Hülse aufgeweitet, so daß der Schlauch verformt und durch diese Verpressung gehalten wird. Diese bekannte Schnellkupplung kann somit nur an Elastomerschläuchen dicht verpreßt werden, wozu ein gesonderter Arbeitsgang mit einer speziellen Verpreßeinrichtung erforderlich ist.A known quick coupling of this type comprises an additional sleeve, which bears against the inside of the hollow component formed by an elastomer hose. For attachment to the elastomeric tube, the inner sleeve is widened so that the tube is deformed and held by this compression. This known quick coupling can thus be tightly pressed only on elastomeric tubes, including a separate operation with a special pressing device is required.

Es ist auch eine Schnellkupplung bekannt, die für ein als Blasformteil ausgeführtes Hohlbauteil geeignet ist. Beim Blasformen des Hohlbauteils wird in dieses eine Nut angeformt, in die ein speziell geformter Drahtring eingesteckt wird. Bei dieser Ausführungsform einer Schnellkupplung kommt es jedoch aufgrund der Herstellung zu Unrundheiten, und bei Temperaturschwankungen treten große Durchmesseränderungen der Dichtung auf.It is also known a quick coupling, which is suitable for a designed as a blow-molded hollow component. When blow molding the hollow component, a groove is formed in this, into which a specially shaped wire ring is inserted. In this embodiment of a quick coupling, however, it comes to roundness due to the production, and in temperature fluctuations occur large changes in diameter of the seal.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Schnellkupplung hinsichtlich der Befestigung der Hülse am Hohlbauteil zu vereinfachen.The invention has for its object to simplify the generic quick coupling with respect to the attachment of the sleeve on the hollow component.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Hohlbauteil aus Kunststoff besteht und als Blasformteil ausgeführt ist, und daß die Hülse beim Blasformen des Hohlbauteils mit diesem eine formschlüssige Verbindung eingeht. Die Schnellkupplung wird somit bereits bei der Herstellung des Hohlbauteils an diesem fixiert, so daß ein zusätzlicher Arbeitsvorgang entfällt.According to the invention, this object is achieved in that the hollow component consists of plastic and is designed as a blow molded part, and that the sleeve during blow molding of the hollow component with this forms a positive connection. The quick coupling is thus already fixed in the manufacture of the hollow component to this, so that an additional operation is eliminated.

Zur Erzielung einer formschlüssigen Verbindung der Hülse mit dem Hohlbauteil kann die Rastnase der Hülse mit dem Kunststoffmaterial des Hohlbauteils ausgefüllt sein. Alternativ oder als zusätzliche Maßnahme kann die Hülse mit mindestens einer Durchbrechung versehen sein, die mit dem Kunststoffmaterial des Hohlbauteils ausgefüllt ist. Weiters kann die dichtungsseitige Stirnseite der Hülse in Verbindung mit dem Kunststoffmaterial als Formschluß dienen.To achieve a positive connection of the sleeve with the hollow component, the latching lug of the sleeve can be filled with the plastic material of the hollow component. Alternatively or as an additional measure, the sleeve may be provided with at least one opening which is filled with the plastic material of the hollow component. Furthermore, the seal-side end face of the sleeve can serve in conjunction with the plastic material as positive engagement.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An embodiment of the invention will be explained in more detail with reference to the drawing.

Die einzige Figur der Zeichnung zeigt einen Längsschnitt durch den mit einer Schnellkupplung versehenen Endbereich eines Rohres.The sole figure of the drawing shows a longitudinal section through the provided with a quick coupling end portion of a tube.

Das Rohr 1 besteht aus Kunststoff und ist als Blasformteil ausgeführt. Bei der Herstellung des Rohres 1 wird eine Hülse 2 aus Metall in das Werkzeug eingelegt und mit dem Rohr 1 formschlüssig verbunden. Die Hülse 2 weist mehrere Rastnasen 3 und Durchbrüche 4 auf, und sie ist am inneren Ende mit einem Anschlagbund 5 versehen. Beim Blasformen des Rohres dringt das Kunststoffmaterial in die Rastnasen 3 und in die Durchbrüche 4 ein so daß eine formschlüssige Verbindung geschaffen wird. Das äußere Ende der Hülse 2 bildet zusammen mit dem Rohr 1 eine Nut 6 für einen Dichtring 7.The pipe 1 is made of plastic and is designed as a blow molded part. In the production of the pipe 1 becomes a sleeve 2 made of metal inserted in the tool and with the pipe 1 positively connected. The sleeve 2 has several locking lugs 3 and breakthroughs 4 on, and she's at the inner end with a stop collar 5 Mistake. When blow molding the tube, the plastic material penetrates into the locking lugs 3 and in the breakthroughs 4 a so that a positive connection is created. The outer end of the sleeve 2 forms together with the pipe 1 a groove 6 for a sealing ring 7 ,

Zur Verbindung des Rohres 1 mit einem Anschlußstutzen, beispielsweise dem Stutzen eines Ladeluftkühlers, wird der Anschlußstutzen auf das Rohr 1 aufgeschoben und mit den Rastnasen 3 in Eingriff gebracht. Zu diesem Zweck kann der Anschlußstutzen in bekannter Weise eine ringförmige Rastfeder aufweisen, die nach erfolgter Aufweitung durch die Rastnasen 3 hinter diesen einrastet.To connect the pipe 1 with a connecting piece, for example, the neck of a charge air cooler, the connecting piece is on the pipe 1 deferred and with the locking lugs 3 engaged. For this purpose, the connecting piece in a known manner having an annular detent spring, which after expansion by the locking lugs 3 snaps behind these.

Wie erkennbar, wird das Rohr 1 im Bereich des Dichtrings 7 von der Metallhülse 2 gestützt. Dadurch sind fertigungsbedingte Unrundheiten beim Formblasen des Rohres 1 ausgeschlossen. Ferner wird die Veränderung des Durchmessers bei Temperaturschwankungen von der Metallhülse 2 bestimmt, die eine wesentlich geringere Wärmeausdehnung als das Kunststoffmaterial des Rohres 1 hat. Damit ist die Dichtheit der Schnellkupplung über einen sehr großen Temperaturbereich gewährleistet.As you can see, the pipe 1 in the area of the sealing ring 7 from the metal sleeve 2 supported. As a result, production-related irregularities in the blow molding of the tube 1 locked out. Further, the change of the diameter in case of temperature fluctuations of the metal sleeve 2 determines that a much lower thermal expansion than the plastic material of the tube 1 Has. Thus, the tightness of the quick coupling is ensured over a very wide temperature range.
