Abstract
Description
Die vorliegende Erfindung betrifft ein Rohr mit einem Abschlußflansch für die Abgase eines Fahrzeugmotors, insbesondere, aber nicht ausschließlich, für den Anschlußflansch zum Auspuffsammelrohr des Motors.The present invention relates to a tube with a End flange for the exhaust gases of a vehicle engine, especially, but not exclusively, for the Connection flange to the exhaust manifold of the engine.
Derzeit besteht die Blockierung zwischen dem Auspuffsammelrohr des Motors und der Auspuffleitung zum Auspufftopf im allgemeinen aus einer mittels Muttern und Schrauben hergestellten Verbindung zwischen den jeweiligen Abschlußflanschen, und die Verbindung zwischen der Auspuffleitung und dem entsprechenden Abschlußflansch wird beispielsweise über eine plastische Verformung der Bauteile selbst bewerkstelligt.There is currently a blockage between the Exhaust manifold of the engine and the exhaust pipe to Muffler generally made from a nut and Screw made connection between the respective End flanges, and the connection between the Exhaust pipe and the corresponding end flange for example, a plastic deformation of the Components accomplished themselves.
Die vorliegende Erfindung dient dem Zweck, eine Rohrleitung mit Abschlußflansch für die Abgase eines Fahrzeugmotors herzustellen, die gegenüber den früheren bekannten Lösungen hinsichtlich der Verbindung zwischen dem Flansch und der Auspuffleitung eine Verbesserung darstellt und folglich verhältnismäßig einfach zu verwirklichen ist und gleichzeitig höchste funktionale Wirksamkeit der Verbindung bei niedrigen Fertigungskosten sicherstellt. The present invention serves the purpose of a Pipe with end flange for the exhaust gases of a Manufacture vehicle engine compared to the previous known solutions regarding the connection between an improvement to the flange and exhaust pipe represents and therefore relatively easy to is realized and at the same time the highest functional Effectiveness of the connection at low manufacturing costs ensures.
Auf Grund der vorliegenden Erfindung wird eine Rohrleitung mit Abschlußflansch für die Abgase eines Fahrzeugmotors ausgeführt, die dadurch gekennzeichnet ist, daß das besagte Rohr für die die Befestigung am erwähnten Flansch mindestens eine Laser-Schweißfläche oder -naht aufweist.On the basis of the present invention, a pipeline with end flange for the exhaust gases of a vehicle engine executed, which is characterized in that the said tube for attachment to the flange mentioned has at least one laser welding surface or seam.
Zum besseren Verständnis der vorliegenden Erfindung werden lediglich als nicht einschränkende Beispiele unter Bezug auf die Zeichnungen zwei besondere Ausführungsformen beschrieben.For a better understanding of the present invention for reference only as non-limiting examples on the drawings two special ones Embodiments described.
Fig. 1 zeigt eine Vorderansicht einer ersten Ausführungsform einer Auspuffleitung, die über einen Abschlußflansch am Auspuffsammelrohr eines Motors im Sinne der vorliegenden Erfindung angekoppelt ist. Fig. 1 shows a front view of a first embodiment of an exhaust pipe which is coupled via an end flange to the exhaust manifold of an engine in the sense of the present invention.
Fig. 2 stellt ein Schnittbild in der Ebene II-II der Rohrleitung mit dem Flansch gemäß Fig. 1 dar. Fig. 2 shows a sectional view in the plane II-II of the pipeline with the flange of FIG. 1.
Fig. 3 zeigt eine Variante der in Fig. 2 dargestellten Ausführung. Fig. 3 shows a variant of the embodiment shown in Fig. 2.
Mit Bezug auf die Fig. 1 und 2 stellt die Nummer 1 eine aus Metall hergestellte Auspuffleitung zum Auspufftopf dar, dessen Anfangsstück innerhalb einer durchgehenden Bohrung 2, die mit einem Flansch 3 abschließt, an ein Auspuffsammelrohr (der Einfachheit halber nicht abgebildet) eines endothermischen Fahrzeugmotors angeschlossen ist; dieser Flansch 3 weist Bohrungen 5 für die (nicht abgebildeten) Schrauben zur Befestigung am Flansch des Auspuffsammelrohrs auf. Zwischen dem Rohr 1 und Flansch 3 ist eine verhältnismäßig kurze Metallbuchse 4 angebracht, die im Sinne der vorliegenden Erfindung sowohl am Flansch 3 als auch am Rohr 1 mittels Laser angeschweißt ist; insbesondere werden zwischen Buchse 4 und Flansch 3 zwei am Umfang verlaufende Rundschweißungen 7 und 8 auf beiden Seiten, oben und unten, am Flansch 3 durchgeführt; ferner erfolgt eine Rundschweißung 9 zwischen Buchse 4 und Rohr 1 an deren vorderen Rändern, die mit der oberen Seite des Flansches 3 abschließen. Diese Laser-Schweißungen können zweckmäßigerweise mit herkömmlichen Schweißgeräten vorgenommen werden.With reference to FIGS. 1 and 2, the number 1 represents a metal exhaust pipe to the muffler, the beginning of which is connected to an exhaust manifold (not shown for the sake of simplicity) of an endothermic vehicle engine within a through bore 2 , which ends with a flange 3 connected; this flange 3 has holes 5 for the screws (not shown) for attachment to the flange of the exhaust manifold. Between the tube 1 and flange 3 , a relatively short metal bushing 4 is attached, which in the sense of the present invention is welded to both the flange 3 and the tube 1 by means of a laser; in particular, two round welds 7 and 8 are carried out on both sides, above and below, between flange 4 and flange 3 on flange 3 ; there is also a circular weld 9 between the socket 4 and the tube 1 at their front edges, which end with the upper side of the flange 3 . These laser welds can expediently be carried out using conventional welding equipment.
In Fig. 3 wird eine Ausführungsvariante dargestellt, bei der die Buchse 4 fehlt und die Rohrleitung 1 unmittelbar über zwei Laser-Rundschweißnähte 7′ und 8′ am Flansch 3 befestigt wird. Auch hier verlaufen die Schweißnähte oben und unten auf dem Flansch 3.In Fig. 3, a variant is shown in which the socket 4 is missing and the pipe 1 is directly attached to the flange 3 via two laser welding seams 7 ' and 8' . Here, too, the weld seams run on the top and bottom of the flange 3 .
Die beschriebene Ausführung der vorliegenden Erfindung bietet daher den Vorteil, daß zwischen Auspuffrohr und Abschlußflansch eine äußerst wirkungsvolle Verbindung erzielt wird, die gegenüber den Abgasen vollkommen dicht ist und in einem automatischen Verfahren hergestellt werden kann mit allen Vorteilen hinsichtlich Verringerung des Zeit- und Kostenaufwandes für die Fertigung, die keine Fachkräfte erfordert.The described embodiment of the present invention therefore offers the advantage that between the exhaust pipe and End flange an extremely effective connection is achieved, which is completely sealed against the exhaust gases is and manufactured in an automatic process can be with all the advantages in terms of reduction the time and cost of manufacturing, which none Skilled workers required.
Schließlich ergibt sich daraus die klare Tatsache, daß die vorliegende Erfindung Änderungen und Varianten unterworfen werden kann, ohne daß damit der Umfang des Erfindungsgedankens gesprengt wird. Unter anderem kann der Flansch 3 auch als Anschlußflansch zum Auspuffsammelrohr des Motors verwendet werden, aber er kann auch als Anschlußflansch zu dazwischengeschalteten Elementen entlang des Auspuffrohres dienen.Finally, it follows from the clear fact that the present invention can be subjected to changes and variants without thereby going beyond the scope of the inventive concept. Among other things, the flange 3 can also be used as a connection flange to the exhaust manifold of the engine, but it can also serve as a connection flange to interposed elements along the exhaust pipe.
