Der Erfindung liegt die Aufgabe zugrunde, einen Abgasturbolader der o. g. Art bzgl. des mechanischen Aufbaus und der Verbindung der Einzelteile miteinander zu verbessern.The invention is based on the object, an exhaust gas turbocharger o. G. Art with respect to the mechanical structure and the connection of the individual parts with each other to improve.
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 abhängigen Ansprüchen angegeben.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 specified in the dependent claims.
Dazu ist es erfindungsgemäß vorgesehen, dass wenigstens ein Stehbolzen vorgesehen ist, welcher den Leitschaufelträger an einer dem Strömungskanal abgewandten Seite an dem Lagergehäuse befestigt, wobei der Stehbolzen strömungskanalseitig über den Leitschaufelträger hinaus ragt und ein Befestigungsmittel für ein Strömungskanalbauteil aufweist, welches zusammen mit dem Leitschaufelträger einen Abschnitt des Strömungskanals in der Turbine des Abgasturboladers ausbildet, wobei der Stehbolzen als Befestigungsmittel für das Strömungskanalbauteil strömungskanalbauteilseitig ein Innengewinde zum Eingriff einer Schraube und das Strömungskanalbauteil eine Öffnung zum Durchgriff der Schraube aufweist.For this purpose, it is provided according to the invention that at least one stud bolt is provided, which secures the guide blade carrier on a side facing away from the flow channel on the bearing housing, the stud protruding flow channel side beyond the guide vane and has a fastening means for a flow channel component, which together with the guide vane one Forming portion of the flow channel in the turbine of the exhaust gas turbocharger, wherein the stud bolt as a fastening means for the flow channel component Strömungskanalbauteilseitig an internal thread for engaging a screw and the flow channel component has an opening for the passage of the screw.
Dies hat den Vorteil, dass bei vereinfachtem mechanischen Aufbau sowie vereinfachter Montierbarkeit im Strömungskanal selbst keine die Strömung störenden Teile mehr vorhanden sind. Hierdurch sind sowohl das Strömungskanalbauteil als auch der Leitschaufelträger mit der variablen Turbinengeometrie am Lagergehäuse mit gemeinsamen Befestigungsmitteln befestigt.This has the advantage that with simplified mechanical design and simplified mounting in the flow channel itself no flow disturbing parts are no longer available. As a result, both the flow channel component and the guide blade carrier with the variable turbine geometry are fastened to the bearing housing with common fastening means.
Zweckmäßigerweise greift wenigstens ein Stehbolzen mit seinem strömungskanalseitig über den Leitschaufelträger hinaus ragenden Teil durch eine Leitschaufel und bildet für diese Leitschaufel eine Schwenkachse aus. Hierdurch wird eine Mehrfachfunktion für den Stehbolzen als Befestigung und Drehachse erzielt, die zusätzliche, eine Strömung störende Teile im Strömungskanal einspart.Expediently, at least one stud bolt engages with its part projecting beyond the guide blade carrier through the flow channel side through a guide blade and forms a pivot axis for this guide blade. As a result, a multiple function for the stud bolt as a fixture and axis of rotation is achieved, which saves additional, a flow disturbing parts in the flow channel.
