Description

Die Erfindung bezieht sich auf eine Verbindungsvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a connecting device according to the preamble of patent claim 1.

Aus der DE 199 59 955 C2 ist eine Verbindungsvorrichtung für Abgasrohre bekannt, die endseitig angeformte und im Querschnitt V-förmig ausgebildete Verbindungselemente aufweisen. Des Weiteren ist aus der WO 02/066801 A1 eine Verbindungsvorrichtung für Abgasrohre bekannt, bei denen das eine Abgasrohr einen nach außen gerichteten Verbindungsflansch und das weitere anschließende Abgasrohr mit einem im Querschnitt etwa V-förmigen Verbindungselement versehen ist.From the DE 199 59 955 C2 a connecting device for exhaust pipes is known, the end formed and formed in cross-section V-shaped connecting elements. Furthermore, from the WO 02/066801 A1 a connecting device for exhaust pipes, in which the one exhaust pipe is provided an outwardly directed connecting flange and the further subsequent exhaust pipe with a cross-sectionally approximately V-shaped connecting element.

Aufgabe der Erfindung ist es, eine verbesserte Verbindungsvorrichtung für Abgasrohre zu schaffen, damit eine Auswechslung eines Katalysators aus einem der Abgasrohre vereinfacht wird und darüber hinaus eine Abnahme der Gastemperatur vor dem Katalysator vermieden wird.The object of the invention is to provide an improved connection device for exhaust pipes, so that a replacement of a catalyst from one of the exhaust pipes is simplified and, moreover, a decrease in the gas temperature is avoided before the catalyst.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the characterizing features of claim 1. Further advantageous features include the subclaims.

Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass zum einen eine schnelle und einfache Auswechselbarkeit eines Katalysators aus dem Aufnahmerohr mittels der Verbindungsvorrichtung gewährleistet ist und zum anderen soll die Gasströmungsführung vor dem Katalysator nicht eingeschränkt sein. Dies wird im Wesentlichen dadurch erzielt, indem mit einem stirnseitigen Flansch des Abgaseintrittsrohres ein im Querschnitt V-förmiges Ringelement verbunden ist, das mit einer seiner Schrägflächen an einer gegenüberstehenden Schrägfläche eines im Querschnitt winkelförmigen Ringelements abgestützt ist. Dieses Ringelement ist mit dem Aufnahmerohr verbunden, wobei das V-förmige Ringelement und das winkelförmige Ringelement gemeinsam von einer V-förmigen Spannschelle einer Verbindungsvorrichtung zusammenhaltend übergriffen sind.The advantages achieved by the invention are that on the one hand a quick and easy replaceability of a catalyst from the receiving tube is ensured by means of the connecting device and on the other hand, the gas flow guide before the catalyst should not be limited. This is achieved essentially by connecting a cross-sectionally V-shaped ring element with an end flange of the exhaust gas inlet tube, which is supported with one of its oblique surfaces on an opposing inclined surface of an angularly angular ring element. This ring member is connected to the receiving tube, wherein the V-shaped ring member and the angular Ring element are overlapped together by a V-shaped clamp of a connecting device together.

Durch diese Ausbildung und Anordnung der Verbindungsvorrichtung ist der Strömungsverlauf im Abgaseintrittsrohr unbehindert durch die Vorrichtung und die Verbindungsvorrichtung kann in einfacher Weise geschlossen und zur Herausnahme des Katalysators geöffnet werden.This design and arrangement of the connecting device, the flow path in the exhaust gas inlet tube unhindered by the device and the connecting device can be closed in a simple manner and opened to remove the catalyst.

Des Weiteren ist nach der Erfindung vorgesehen, dass der stirnseitige Flansch des Abgaseintrittsrohres sich radial nach außen erstreckt und in einer Ebene mit einem gegenüberstehenden Verbindungsflansch des V-förmigen Ringelements angeordnet ist, das das Aufnahmerohr von außen übergreift. Durch diese Ausbildung des Verbindungselements am Abgaseintrittsrohr wird ein minimaler Bauraum benötigt und die Ausmündungsfläche des Abgasaustrittsrohres entspricht nahezu dem Durchmesser bzw. dem Einmündungsquerschnitt des Katalysators.Furthermore, it is provided according to the invention that the end flange of the exhaust gas inlet tube extends radially outward and is arranged in a plane with an opposite connecting flange of the V-shaped ring member which engages over the receiving tube from the outside. As a result of this design of the connecting element on the exhaust gas inlet pipe, a minimal installation space is required and the outlet area of the exhaust gas outlet pipe corresponds almost to the diameter or the cross-section of the catalyst.

Ferner ist nach der Erfindung vorgesehen, dass das winkelförmige Ringelement mit einem Schenkel im Bereich der Isolierung des Katalysators angeordnet und mit dem Aufnahmerohr in diesem Bereich verbunden ist, wobei der weitere anschließende Schenkel die Schrägfläche des V-förmigen Ringelements von außen übergreift und korrespondierend mit diesem angeordnet ist. Durch die Verbindung des winkelförmigen Ringelements mit seinem einen Schenkel auf dem Aufnahmerohr im Bereich der Isolierung des Katalysators wird keine nachteilige Abnahme der Gastemperatur vor dem Katalysator erzeugt, so dass die Abgastemperatur nicht durch thermische Massen herabgesetzt wird.It is further provided according to the invention that the angular ring member is arranged with a leg in the region of the insulation of the catalyst and connected to the receiving tube in this area, the further adjoining leg engages over the inclined surface of the V-shaped ring member from the outside and corresponding thereto is arranged. By connecting the angular ring element with its one leg on the receiving tube in the region of the insulation of the catalyst, no disadvantageous decrease in the gas temperature is generated before the catalyst, so that the exhaust gas temperature is not reduced by thermal masses.

Nach einer nicht erfindungsgemäßen Vorrichtung ist vorgesehen, dass das Abgaseintrittsrohr sowie das Aufnahmerohr jeweils mit einem im Querschnitt winkelförmigen Ringelement verbunden ist, die beide einen in einer Ebene radial vorragenden Befestigungsflansch aufweisen, welche gegenüberstehend und miteinander verbindbar sind. Auch bei dieser Vorrichtung liegt das mit dem Aufnahmerohr verbundene winkelförmige Ringelement mit seinem einen Schenkel im Bereich der Isolierung des Katalysators und ist mit dem Aufnahmerohr verbunden. Durch diese Vorrichtung wird eine einfache schnell zu lösende und zu schließende Verbindungsvorrichtung von Abgasrohren geschaffen, die ebenfalls alle Vorteile der vorgenannten Vorrichtung umfasst, wie insbesondere die Strömungsführung und die Gastemperatur vor dem Katalysator.According to a device not according to the invention, it is provided that the exhaust gas inlet tube and the receiving tube are each connected to an annular cross-section annular element, both of which have a mounting flange projecting radially in a plane, which faces and with each other are connectable. In this device too, the angular ring element connected to the receiving tube lies with its one leg in the region of the insulation of the catalyst and is connected to the receiving tube. By this device, a simple quick to be solved and closed connecting device of exhaust pipes is provided, which also includes all the advantages of the aforementioned device, in particular the flow control and the gas temperature upstream of the catalyst.

Nach einer nicht erfindungsgemäßen Vorrichtung ist das winkelförmige Ringelement endseitig des Gaseintrittsrohres angeformt und das V-förmige weitere Ringelement ist mit einem Schenkel am Aufnahmerohr im Bereich der Isolierung befestigt.According to a device not according to the invention, the angular ring element is integrally formed on the end side of the gas inlet tube and the V-shaped further ring element is fastened with a leg on the receiving tube in the region of the insulation.
