Description
Die Erfindung betrifft einen Abgasturbolader für eine Brennkraftmaschine, insbesondere eines Kraftfahrzeuges, mit einem Turbinengehäuse, einem Lagergehäuse, einem Turbinenrad, einem Leitschaufelträger und Leitschaufeln, welche in einem um das Turbinenrad herum ausgebildeten Ringkanal schwenkbar angeordnet sind, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an exhaust gas turbocharger for an internal combustion engine, in particular of a motor vehicle, with a turbine housing, a bearing housing, a turbine wheel, a guide vane carrier and guide vanes, which are arranged pivotably in an annular channel formed around the turbine wheel, according to the preamble of patent claim 1.

Der Erfindung liegt die Aufgabe zugrunde, einen Aufbau und eine Montage eines Abgasturboladers bei gleichzeitig verbesserter Funktionsfähigkeit bzgl. Gasdichtheit an kritischen Stellen zu vereinfachen.The invention has for its object to simplify a structure and a mounting of an exhaust gas turbocharger at the same time improved functionality with respect. Gas-tightness at critical points.
Diese Aufgabe wird erfindungsgemäß durch einen Abgasturbolader der o. g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by an exhaust gas turbocharger o. G. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.
Dazu ist es bei einem Abgasturbolader der o. g. Art erfindungsgemäß vorgesehen, dass zur Befestigung des Leitschaufelträgers wenigstens ein Federelement angeordnet ist, welches den Leitschaufelträger gegen das Lagergehäuse drückt.For this it is in an exhaust gas turbocharger o. G. Art according to the invention provided that at least one spring element is arranged for fixing the guide vane carrier, which presses the guide vane carrier against the bearing housing.
Dies hat den Vorteil, dass eine Montage des Abgasturboladers vereinfacht ist und weniger Bauteile benötigt werden, wobei gleichzeitig ein Leitschaufelklemmen wirksam vermieden und Spalte im Strömungsweg minimiert sind.This has the advantage that an assembly of the exhaust gas turbocharger is simplified and fewer components are needed, at the same time a Leitschaufelklemmen effectively avoided and gaps in the flow path are minimized.
Dadurch, dass ein Strömungskanalbauteil vorgesehen ist, welches zusammen mit dem Leitschaufelträger den Ringkanal ausbildet und im weiteren Strömungsverlauf einen axialen Strömungskanal um das Turbinenrad herum ausbildet, wobei das Strömungskanalbauteil und der Leitschaufelträger als Leitschaufelverstellmodul miteinander verbunden sind, ergibt sich der zusätzliche Vorteil, dass bei der Montage des Abgasturboladers dieses Leitschaufelverstellmodul als komplette Einheit in das Lagergehäuse montiert werden kann.The fact that a flow channel component is provided which forms the annular channel together with the guide vane and forms an axial flow channel around the turbine wheel in the further flow, wherein the flow channel component and the vane support are connected to each other as Leitschaufelverstellmodul, there is the additional advantage that in the Assembly of the exhaust gas turbocharger this Leitschaufelverstellmodul can be mounted as a complete unit in the bearing housing.
Beispielsweise ist das Federelement ein Wärmeschutzblech, welches bevorzugt derart angeordnet ist, dass es einen axialen Strömungskanal um das Turbinenrad herum axial in Richtung Lagergehäuse begrenzt.For example, the spring element is a heat shield, which is preferably arranged such that it limits an axial flow channel around the turbine wheel axially in the direction of the bearing housing.
Zweckmäßigerweise ist das Wärmeschutzblech axial mittels einer Verschraubeinheit am Lagergehäuse befestigt.Conveniently, the heat shield is attached axially by means of a screw on the bearing housing.
Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in der einzigen Fig. eine bevorzugte Ausführungsform eines erfindungsgemäßen Abgasturboladers in perspektivischer, teilweise geschnittener Ansicht.The invention will be explained in more detail below with reference to the drawing. This shows in the only Fig. A preferred embodiment of an exhaust gas turbocharger according to the invention in a perspective, partially sectioned view.
Die aus der einzigen Fig. ersichtliche bevorzugte Ausführungsform eines erfindungsgemäßen Abgasturboladers für eine Brennkraftmaschine umfasst ein Turbinenrad
Das Strömungskanalbauteil
Bei dem Leitschaufelverstellmodul sind der Leitschaufelträger
Das Leitschaufelverstellmodul als solches bringt neben Montagevorteilen das Vermeiden von Leitschaufelklemmen und Spalteminimierungen zwischen Turbinenrad
Ein besonderer Vorteil der erfindungsgemäßen Lösung liegt auch darin, dass das Leitschaufelverstellmodul bestehend aus Leitschaufeln
