Abstract

The exhaust manifold (14) of the engine is attached with a flange (12) over the engine outlet ports. The outlet pipes of the manifold converge into a single outlet (16) which is turned down to form a shoulder (16b). The turbine housing (18) of the turbo-charger has an inlet (20) in the form of a tubular extension of the housing. The bore of this inlet incorporates a counterbore. This counterbore is a press fit over the stepped down outer diameter of the outlet of the exhaust manifold, while the shoulder on this outlet sits against the outer face of the inlet to the turbocharger. Alternatively the bore of the turbine inlet can be shrunk onto the outlet of the manifold. Relative rotary movement of the parts is prevented by a pin which is mounted in slots which are milled in the matching diameters of the connection.

Es wird somit unter Verzicht auf relativ schwere und baulich voluminöse Flansche vorgeschlagen, die rohrförmigen Befestigungsabschnitte mit Preßsitz, bevorzugt mit Schrumpfsitz, ineinanderzufügen. Die damit erziel­ bare, kraftschlüssig wirkende Pressung reicht aus, um auch unter Berück­ sichtigung der auftretenden hohen Temperaturen und Temperaturschwan­ kungen eine zuverlässige und zugleich dauerhaft gasdichte Befestigung zu schaffen.It is therefore relatively heavy and structurally voluminous Flanges suggested using the tubular mounting sections Press fit together, preferably with a shrink fit. The achieved with it clear, non-positive pressure is sufficient to withstand taking into account the high temperatures and temperature fluctuations that occur a reliable and at the same time permanently gastight fastening create.

Aus Montagegründen und zur baulichen Fixierung der Abgasleitung, z. B. dem Befestigungsabschnitt eines Abgaskrümmers, und des Turbinengehäu­ ses des Abgasturboladers wird ferner vorgeschlagen, die beiden Bauteile in Umfangsrichtung formschlüssig zu fixieren, insbesondere mittels eines in Axialnuten eingreifenden Stiftes.For reasons of assembly and for structurally fixing the exhaust pipe, e.g. B. the mounting portion of an exhaust manifold, and the turbine housing ses of the exhaust gas turbocharger is also proposed, the two components in  To fix the circumferential direction positively, in particular by means of a Axial grooves engaging pin.

Aufgrund der starken Temperaturschwankungen sollten ferner besonders zweckmäßig die Abgasleitung und das Turbinengehäuse aus Materialien mit im wesentlichen gleichen Ausdehnungskoeffizienten, z. B. aus einem hochtemperaturfesten Grauguß oder Stahlguß, hergestellt sein.Due to the strong temperature fluctuations should also be special expediently with the exhaust pipe and the turbine housing made of materials essentially the same coefficient of expansion, e.g. B. from one high temperature resistant cast iron or cast steel.

Ein Ausführungsbeispiel der Erfindung ist im folgenden mit weiteren Einzel­ heiten näher erläutert. Die schematische Zeichnung zeigt inAn embodiment of the invention is in the following with further details explained in more detail. The schematic drawing shows in

Fig. 1 in einem Teillängsschnitt einen Abgaskrümmer einer mehrzylindrigen Brennkraftmaschine mit daran befestigtem Turbinengehäuse eines Abgasturboladers und Fig. 1 in a partial longitudinal section an exhaust manifold of a multi-cylinder internal combustion engine with attached turbine housing of an exhaust gas turbocharger and

Fig. 2 einen Schnitt gemäß Linie II-II der Fig. 1 durch die Befestigungsstelle. Fig. 2 shows a section along line II-II of Fig. 1 through the attachment point.

In der Zeichnung ist mit 10 ein Abgaskrümmer einer mehrzylindrigen Brenn­ kraftmaschine bezeichnet, der sich im wesentlichen aus einem an dem nicht dargestellten Zylinderkopf einer Brennkraftmaschine befestigtem Flansch 12, mehreren Einzelrohren 14 und einem ebenfalls rohrförmigen Befestigungs­ abschnitt 16 zusammensetzt. Die Einzelrohre 14 sind im Befestigungsab­ schnitt 16 zusammengeführt.In the drawing, 10 denotes an exhaust manifold of a multi-cylinder internal combustion engine, which is composed essentially of a flange 12 , a plurality of individual pipes 14 and a likewise tubular fastening section 16 , which is fastened to the cylinder head of an internal combustion engine (not shown). The individual tubes 14 are merged in the fastening section 16 .

An den Befestigungsabschnitt 16 des Abgaskrümmers 10 ist das Turbinen­ gehäuse 18 eines Abgasturboladers im übrigen herkömmlicher Bauart über einen ebenfalls rohrförmigen Befestigungsabschnitt 20 angeschlossen. Die Abgasturbine sowie die Verdichterstufe des Abgasturboladers sind nicht dargestellt.At the fastening section 16 of the exhaust manifold 10 , the turbine housing 18 of an exhaust gas turbocharger in the rest of the conventional design is connected via a likewise tubular fastening section 20 . The exhaust gas turbine and the compressor stage of the exhaust gas turbocharger are not shown.

Die rohrförmigen Befestigungsabschnitte 16, 20 (vgl. auch Fig. 2) sind teles­ kopartig ineinandergeschoben, wobei aufgrund der maßlichen Überdeckung zwischen dem Außendurchmesser des krümmerseitigen Befestigungsab­ schnittes 16 und dem Innendurchmesser des turbinenseitigen Befestigungs­ abschnittes 20 in deren sich überdeckenden Umfangsbereichen eine kraft­ schlüssige Verbindung hergestellt ist, die auch unter Berücksichtigung der hohen auftretenden Temperaturen und der starken Temperaturschwankun­ gen dauerhaft gasdicht und fest ist. The tubular fastening sections 16 , 20 (cf. also FIG. 2) are telescopically pushed into one another, due to the dimensional overlap between the outer diameter of the manifold-side fastening section 16 and the inner diameter of the turbine-side fastening section 20 in the overlapping circumferential regions of which a positive connection is produced is, which is permanently gas-tight and solid, taking into account the high temperatures and the strong temperature fluctuations.

Zudem sind sowohl der Abgaskrümmer 10 als auch das Turbinengehäuse 18 aus dem gleichen Werkstoff, insbesondere aus einem hoch legiertem Grauguß hergestellt, so daß beide Bauteile den gleichen Ausdehnungskoef­ fizienten aufweisen. Dadurch ist ebenfalls sichergestellt, daß die durch den Schrumpfsitz hergestellte Bauteilspannung im Befestigungsbereich im we­ sentlichen gleich bleibt.In addition, both the exhaust manifold 10 and the turbine housing 18 are made of the same material, in particular of a high-alloy gray cast iron, so that both components have the same coefficient of expansion. This also ensures that the component tension produced by the shrink fit remains essentially the same in the fastening area.

Zur Lagefixierung des Abgaskrümmers 10 zum Turbinengehäuse 18 in Um­ fangsrichtung sind in den Außenumfang des Befestigungsabschnittes 20 und in den Innenumfang des Befestigungsabschnittes 16 axial verlaufende Nuten 16a bzw. 20a eingearbeitet, in die ein Stift 22 eingesetzt ist. Eine axiale Fixierung bzw. eine definierte Einschubtiefe der beiden Befestigungs­ abschnitte 16, 20 zueinander ist aufgrund der abgestuften Ausführung der Befestigungsabschnitte 16, 20 bzw. der dadurch gebildeten Ringschultern 16b bzw. 20b gegeben.To fix the position of the exhaust manifold 10 to the turbine housing 18 in order circumferential direction of the fixing portion 20 and into the inner periphery of the fixing portion axially extending grooves 16 16 are a in the outer circumference or a incorporated 20 into which a pin is inserted 22nd Axial fixing or a defined insertion depth of the two fastening portions 16, 20 to each other of the attachment portions 16, 20 and the annular shoulders formed thereby is 16 b, where b and 20 due to the stepped embodiment.

Bei der Fertigung des Abgaskrümmers 10 bzw. des Turbinengehäuses 18 werden die korrespondierenden Durchmesser der Befestigungsabschnitte 16, 20 mit einer definierten Überdeckung hergestellt. Nach dem Einfräsen der Axialnuten 16a, 20a und Bereitstellung des Stiftes 22 wird das Turbinen­ gehäuse 18 auf eine definierte Temperatur erhitzt und/oder der Abgaskrüm­ mer 10 auf eine definierte Minustemperatur heruntergekühlt und dann unter Zwischenfügung des Stiftes 22 die beiden Befestigungsabschnitte 16, 20 in­ einandergeschoben. Aufgrund des sich einstellenden Temperaturausglei­ ches wird im Befestigungsbereich eine definierte Vorspannung erzeugt, die eine feste kraftschlüssige Verbindung sicherstellt.When manufacturing the exhaust manifold 10 or the turbine housing 18 , the corresponding diameters of the fastening sections 16 , 20 are produced with a defined overlap. After milling the axial grooves 16 a, 20 a and providing the pin 22 , the turbine housing 18 is heated to a defined temperature and / or the exhaust manifold 10 is cooled down to a defined sub-zero temperature and then, with the pin 22 interposed, the two fastening sections 16 , 20 pushed into each other. Due to the temperature compensation, a defined pre-tension is generated in the fastening area, which ensures a firm, non-positive connection.
