In this case, the tulip-on fastening section (14) of the first exhaust gas-carrying component (10) is formed in one piece with it and a centering tube (20) is inserted and fastened in the tulip-on fastening section (14) of the first exhaust gas-carrying component (10) such that the centering tube ( 20) protrudes from the topped mounting section (14) of the first exhaust gas-carrying component (10) and, when the first and second exhaust gas-carrying component (10, 12) are plugged together, engages in an inner circumference of the second exhaust-gas-carrying component (12) in the region of the annular bead (16) and the first component (10) is centered with respect to the second component (12).
Description
Die Erfindung betrifft eine Abgasanlage einer Brennkraftmaschine, insbesondere eines Kraftfahrzeuges, mit wenigstens zwei abgasführenden Bauteilen, wobei ein aufgetulpt ausgebildeter Befestigungsabschnitt eines ersten abgasführenden Bauteils an einer Ringwulst eines zweiten abgasführenden Bauteils anschlägt und der aufgetulpte Befestigungsabschnitt des ersten abgasführenden Bauteils mit dem Ringwulst des zweiten abgasführenden Bauteils über eine Schelle verbunden ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an exhaust system an internal combustion engine, in particular a motor vehicle, with at least two exhaust gas Components, with a sculpted formed fastening section of a first exhaust gas-carrying Strikes component on an annular bead of a second exhaust gas-carrying component and the topped attachment section of the first exhaust gas Component with the annular bead of the second exhaust gas-carrying component over a Clamp is connected, according to the generic term of claim 1.
Die Anbindung eines Abgasführungselementes
an einen Turbolader erfolgt beispielsweise durch verschraubbare
Flansche, wie aus der
Bei einer alternativen Befestigung zwischen Abgasrohr und Turbolader ist es bekannt, am Befestigungsabschnitt des Abgasrohres außen ein Rohr überzustülpen, welches aufgetulpt ausgebildet ist und an einem Wulst am Befestigungsabschnitt des Turboladers anschlägt. Der aufgetulpte Bereich des Abgasrohres ist mit dem Wulst des Turboladers mittels einer V-Schelle verbunden. Das auf das Abgasrohr aufgeschobene Rohr muß zur Befestigung sowie Abdichtung über den ganzen Umfang mit dem Abgasrohr durch eine Schweißverbindung verbunden werden. Dies hat den Nachteil, daß der Kraftfluß durch die Schweißnaht unterbrochen ist, was die Beanspruchung dieses ohnehin hoch belasteten Bereiches zusätzlich erhöht. Ferner ist eine dichtgeschweißte Umfangsnaht erforderlich. Dies ist kostenintensiv und schränkt die Gestaltbarkeit der Abgasführung ein, da die Zugänglichkeit für einen entsprechenden Schweißbrenner gewährleistet sein muß.With an alternative attachment between the exhaust pipe and turbocharger, it is known on the fastening section of the exhaust pipe outside to put a pipe on which is formed on sculpt and on a bead on the fastening section of the turbocharger. The flared area of the exhaust pipe is with the bulge of the turbocharger connected by means of a V-clamp. The one pushed onto the exhaust pipe Pipe must go to Fastening and sealing via the entire circumference with the exhaust pipe through a welded joint get connected. This has the disadvantage that the power flow through the weld is interrupted, what the strain of this already highly stressed Additional area elevated. Furthermore is a tightly welded Circumferential seam required. This is expensive and limits the flexibility the exhaust system one because of accessibility for one corresponding welding torch guaranteed have to be.
Der Erfindung liegt die Aufgabe zugrunde, eine Abgasanlage der obengenannten Art bzgl. der Verbindung zwischen zwei abgasführenden Teilen, insbesondere zwischen Abgasrohr und Turbolader, zu verbessern.The invention has for its object a Exhaust system of the type mentioned above with regard to the connection between two exhaust gas-carrying Parts, especially between the exhaust pipe and turbocharger to improve.
Diese Aufgabe wird erfindungsgemäß durch eine Abgasanlage der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a Exhaust system of the above Kind with those characterized in claim 1 Features resolved. Advantageous embodiments of the invention are specified in the dependent claims.
Dazu ist es erfindungsgemäß vorgesehen, daß der aufgetulpte Befestigungsabschnitt des ersten abgasführenden Bauteils einstöckig mit diesem ausgebildet ist und daß in den aufgetulpten Befestigungsabschnitt des ersten abgasführenden Bauteils ein Zentrierrohr derart eingeschoben und befestigt ist, daß das Zentrierrohr aus dem aufgetulpten Befestigungsabschnitt des ersten abgasführenden Bauteils heraus ragt und bei zusammenstecken von erstem und zweitem Bauteil in einen Innenumfang des zweiten abgasführenden Bauteils im Bereich des Ringwulstes eingreift und das erste Bauteil bzgl. des zweiten Bauteils zentriert.For this purpose, it is provided according to the invention that the tulip-on Fastening section of the first exhaust gas-carrying component in one piece with this is trained and that in the topped mounting section of the first exhaust gas A centering tube is inserted and fastened in this way, that this Centering tube from the topped mounting section of the first exhaust-carrying Component protrudes and when the first and second are put together Component in an inner circumference of the second exhaust gas-carrying component in the area engages the annular bead and the first component with respect to the second Component centered.
Dies hat den Vorteil, daß ein Kraftfluß über die Verbindung zwischen erstem und zweitem Bauteil ohne Unterbrechung durch eine Schweißnaht gewährleistet ist und eine kostenintensive, dichtgeschweißte Umfangsnaht entfällt. Dadurch besteht mehr Spielraum zur optimalen Ausnutzung eines vorgegebenen Bauraums, um beispielsweise eine Katalysatoranströmung zu verbessern.This has the advantage that a power flow over the Connection between first and second component without interruption through a weld guaranteed and a cost-intensive, tightly welded peripheral seam is not necessary. Thereby there is more scope for optimal use of a given one Space to, for example, a flow of catalyst improve.
In einer besonders bevorzugten Ausführungsform ist das erste abgasführende Bauteil ein Abgasführungselement, insbesondere ein Abgaskrümmer, das zweite abgasführende Bauteil ein Abgasturbolader und die Schelle eine V-Schelle.In a particularly preferred embodiment is the first exhaust gas Component an exhaust gas guide element, especially an exhaust manifold, the second exhaust gas Component an exhaust gas turbocharger and the clamp a V-clamp.
Eine besonders einfach herzustellende und trotzdem mechanisch stabile Befestigung des Zentrierrohres erzielt man dadurch, daß das Zentrierrohr mittels einer stoffschlüssigen Verbindung, insbesondere mittels Punktschweißen, am Innenumfang des ersten abgasführenden Bauteils befestigt ist.A particularly easy to manufacture and still achieved mechanically stable attachment of the centering tube one by the fact that Centering tube by means of a material connection, in particular by means of spot welding, on the inner circumference of the first exhaust gas Component is attached.
In einer alternativen Ausführungsform ist das Zentrierrohr mittels einer formschlüssigen Verbindung, insbesondere mittels einer Verprägung, am Innenumfang des ersten abgasführenden Bauteils befestigt.In an alternative embodiment is the centering tube by means of a positive connection, in particular by means of embossing, on the inner circumference of the first exhaust gas Component attached.
Weitere Merkmale, Vorteile und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen, sowie aus der nachstehenden Beschreibung der Erfindung anhand der beigefügten Zeichnungen. Diese zeigen inOther features, advantages and advantageous configurations the invention result from the dependent claims, as well from the following description of the invention with reference to the accompanying drawings.
