Description

Das folgende betrifft eine Rohrverbindung, insbesondere Zum Befestigen eines Wellrohres an einem anschraubbaren Anschlußstutzen. Eingesetzt wird die Rohrverbindung bei Brennkraftmaschinen im Abgasstrang.The following relates to a pipe joint, in particular For attaching a corrugated pipe to a screwable one Connecting piece. The pipe connection is used for Internal combustion engines in the exhaust system.

Eine gattungsgemäße Rohrverbindung ist aus der DE-OS 19 59 098 bekannt. Diese Rohrverbindung ist aufwendig, da sie mehrere, in einer vorgegebenen Reihenfolge zusammenzu­ setzende Bauteile aufweist und unter genauer Beachtung von aufeinanderfolgenden Arbeitsschritten zusammenzubauen ist. Ein zerstörungsfreies komplettes Demontieren der Bauteile ist nicht möglich.A generic pipe connection is from DE-OS 19 59 098 known. This pipe connection is complex because them together, in a given order has setting components and with close attention to successive work steps. A non-destructive complete disassembly of the components can not.

Der Erfindung liegt die Aufgabe zugrunde, eine Rohrverbin­ dung bereitzustellen, die aus wenigen EinZelteilen be­ steht, einfach montierbar und vollständig zerstörungsfrei demontierbar ist.The invention has for its object a pipe joint to be made available that consist of a few individual parts stands, easy to assemble and completely non-destructive is removable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Rohrende einen an eine konische Ringfläche eines Anschluß­ stutzens anschließenden zylindrischen Fortsatz aufweist, der auf einen in den Anschlußstutzen eingearbeiteten um­ laufenden Abstich, der in die Anlagefläche ausläuft, auf­ geschoben ist. Mit dem auf den Abstich augeschobenen Fortsatz wird eine Montageerleichterung ermöglicht, da nach dem Zusammenstecken der Teile diese zueinander aus­ gerichtet und fixiert sind. Dabei kann bei Bedarf in den Abstich eine mit den Fortsatz zusammenwirkende Nut-Nasen- Einrichtung eingearbeitet sein, die ein verdrehgesichertes Montieren der Bauteile gewährleistet. Dies ist beispiels­ weise bei gebogenen Rohren hilfreich. Durch den zylindri­ schen Fortsatz kann zudem die Dichtfläche durch entspre­ chende Wahl der Befestigungseinrichtung vergrößert werden. Es ist im Rahmen der Erfindung vorgesehen, auch diese Flä­ che durch eine entsprechend ausgebildete Befestigungs­ schelle als Dichtfläche zu nutzen.This object is achieved in that the Pipe end one on a conical ring surface of a connection has adjacent cylindrical extension,  the one built into the connecting piece ongoing racking that ends in the contact surface is pushed. With the one pushed onto the rack Ease of assembly is facilitated because after plugging the parts together from each other are directed and fixed. If necessary, the Tapping a groove-nose cooperating with the extension Facility to be incorporated, which is an anti-rotation Assembling the components guaranteed. This is an example useful for bent pipes. By the cylindri extension can also correspond to the sealing surface appropriate choice of the fastening device can be enlarged. It is provided in the context of the invention, these flä che by an appropriately trained attachment clamp to use as a sealing surface.

In Weiterbildung der Erfindung ist vorgesehen, daß die Tiefe des Abstiches der Dicke der Rohrwand des Fortsatzes entspricht, und daß die Breite des Abstiches zumindest der Länge des Fortsatzes entspricht. Durch die erfindungsgemä­ ße Festlegung der Tiefe wird ein verspannungsfreies Be­ festigen des Rohrendes an dem Anschlußstutzen ermöglicht. Die Breite des Abstiches ist vorteilhaft geringfügig grö­ ßer als die Länge des Fortsatzes, damit dieser unter allen Umständen vollständig auf den Abstich aufgeschoben werden kann und die konischen Anlageflächen zusammenwirken.In a development of the invention it is provided that the Depth of the thickness of the pipe wall of the extension corresponds, and that the width of the rack is at least that The length of the extension corresponds. By the invention The definition of the depth becomes a stress-free loading allows the pipe end to be fixed to the connecting piece. The width of the rack is advantageously slightly larger greater than the length of the extension, so that this under all Circumstances may be pushed onto the rack can and the conical contact surfaces interact.

Weitere Vorteile der Erfindung sind der Zeichnungsbe­ schreibung zu entnehmen, in der ein in der einzigen Figur dargestelltes Ausführungsbeispiel der Erfindung näher be­ schrieben ist. Ein Anschlußstutzen 1 weist in dem nicht dargestellten Teil eine Befestigungsvorrichtung, vorzugs­ weise in Form eines Schraubgewindes auf. Mit der Befesti­ gungsvorrichtung wird der Anschlußstutzen 1 vorzugsweise an Brennkraftmaschinen am Abgassystem befestigt. Anschlie­ ßend an die Befestigungsvorrichtung weist der Anschluß­ stutzen 1 einen Schlüsselbereich 2 auf, auf den ein ge­ eigneter Schlüssel aufgeschoben werden kann, mit dessen Hilfe der Anschlußstutzen insbesondere bei Ausstattung mit einem Gewinde gedreht werden kann. Anschließend an den Schlüsselbereich 2 folgt ein Einstich 3, der in eine konische Schulter 4 übergeht. Der Schulter 4 schließt sich ein zylindrischer Bereich 5 an, in den ein Abstich 6 ein­ gearbeitet ist. Der Abstich 6 läuft endseitig des An­ schlußstutzens 1 in eine konische Anlagefläche 7 aus, gegen die eine ebenfalls konisch ausgebildete Ringfläche 8 des Rohrendes von einer Befestigungsvorrichtung, die als Schelle 9 ausgebildet ist, gedrückt wird. An die Ringflä­ che 8 schließt sich ein zylindrischer Fortsatz 10 an, der auf den Abstich 6 aufgeschoben wird.Further advantages of the invention can be found in the description of the drawing, in which an embodiment of the invention shown in the single figure is described in more detail. A connecting piece 1 has in the part not shown a fastening device, preferably in the form of a screw thread. With the fastening device, the connecting piece 1 is preferably attached to internal combustion engines on the exhaust system. Subsequently to the fastening device, the connecting piece 1 has a key area 2 , onto which a suitable key can be pushed, with the aid of which the connecting piece can be rotated, in particular when equipped with a thread. Subsequent to the key area 2 , a recess 3 follows, which merges into a conical shoulder 4 . The shoulder 4 is followed by a cylindrical region 5 , in which a tapping 6 is worked. The racking 6 runs at the end of the connection piece 1 in a conical contact surface 7 , against which a likewise conical annular surface 8 of the pipe end is pressed by a fastening device which is designed as a clamp 9 . At the Ringflä surface 8 is followed by a cylindrical extension 10 which is pushed onto the rack 6 .

Die Tiefe T des Abstiches entspricht der Dicke der Wandung des Fortsatzes 10, die in der Regel der Wandstärke des Rohres entspricht. Die Breite B des Abstiches ist in dem dargestellten Ausführungsbeispiel geringfügig größer als die Länge des Fortsatzes 10. Dadurch ist sichergestellt, daß der Fortsatz 10 soweit auf den Abstich 6 aufgeschoben werden kann, bis die Ringfläche 8 vollständig auf der An­ lagefläche 7 aufliegt und von der Schelle 9 in dieser Position gehalten wird. Die Schelle 9 kann im übrigen als ein- oder zwei-geteilte Schelle ausgebildet sein. Weiter­ hin ist vorgesehen, die Schelle 9 so auszubilden, daß sie mit ihrer Fläche 9a auf dem Fortsatz 10 aufliegt und die­ sen gegen den Anschlußstutzen 1 drückt. The depth T of the tapping corresponds to the thickness of the wall of the extension 10 , which generally corresponds to the wall thickness of the tube. The width B of the tapping is slightly larger than the length of the extension 10 in the exemplary embodiment shown. This ensures that the extension 10 can be pushed onto the rack 6 until the ring surface 8 rests completely on the contact surface 7 and is held in this position by the clamp 9 . The clamp 9 can also be designed as a one or two-part clamp. Next is toward provided which clamp 9 to form so that it rests with its surface 9 a on the extension 10 and the sen against the connection piece 1 presses.

Neben den zuvor beschriebenen Vorteilen wird durch die er­ findungsgemäße Ausbildung darüberhinausgehend ein Verkei­ len oder Verklemmen der Schelle 9 sicher vermieden, das sich einstellen könnte, wenn das Rohrende ohne die erfin­ dungsgemäße Ausgestaltung an dem Anschlußstutzen 1 be­ festigt würde. Dies würde unter anderem durch die auf der Schulter 4 und der Anlagefläche 7 und dem Fortsatz 10 auf­ liegenden Schelle 9 wegen der unterschiedlichen Durchmes­ ser und Höhen einstellen.In addition to the advantages described above, he was also able to reliably avoid a jamming or jamming of the clamp 9 by the design according to the invention, which could occur if the pipe end without the design according to the invention were fastened to the connecting piece 1 . This would adjust, inter alia, by lying on the shoulder 4 and the contact surface 7 and the extension 10 on the lying clamp 9 because of the different diam.
