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 Abgasturbolader der o. g. Art bzgl. der Befestigung des Leitschaufelträgers zu verbessern.The invention is based on the object, an exhaust gas turbocharger o. G. Art regarding the attachment of the vane support 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 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 der Leitschaufelträger mittels eines Bajonett-Verschlusses am Lagergehäuse befestigt ist.For this it is in an exhaust gas turbocharger o. G. Art provided according to the invention, that the guide vane carrier is fastened by means of a bayonet lock on the bearing housing.
Dies hat den Vorteil, dass die Befestigung der Anordnung der variablen Turbinengeometrie (VTG-Modul) mit einem Leitschaufelträger, beweglichen Leitschaufeln und einem Verstellring über den Leitschaufelträger am Lagergehäuse eine Entkopplung von einem Abgaskrümmermodul der Brennkraftmaschine bewirkt. Zusätzlich wird eine einfache, montagefreundliche und kostengünstige Anbindung des VTG-Moduls zur Verfügung gestellt.This has the advantage that the attachment of the arrangement of the variable turbine geometry (VTG module) with a guide vane carrier, movable guide vanes and an adjusting ring on the guide plate carrier on the bearing housing causes a decoupling of an exhaust manifold of the internal combustion engine. In addition, a simple, easy to install and cost-effective connection of the VTG module is provided.
In einer bevorzugten Ausführungsform umfasst der Bajonett-Verschluss wenigstens ein Stiftelement und wenigstens eine mit dem Stiftelement zusammenwirkende Rastnut, wobei das wenigstens eine Stiftelement am Leitschaufelträger und die wenigstens eine Rastnut am Lagergehäuse oder umgekehrt das wenigstes eine Stiftelement am Lagergehäuse und die wenigstens eine Rastnut am Leitschaufelträger ausgebildet ist.In a preferred embodiment, the bayonet closure comprises at least one pin element and at least one detent groove cooperating with the pin element, the at least one pin element on the guide blade carrier and the at least one detent groove on the bearing housing or vice versa the least one pin element on the bearing housing and the at least one detent groove on the guide blade carrier is trained.
Zweckmäßigerweise ist am Lagergehäuse ein Absatz, beispielsweise in Form eines Angusses, ausgebildet, in dem die wenigstens eine Rastnut ausgebildet ist.Conveniently, a shoulder, for example in the form of a sprue, formed on the bearing housing, in which the at least one locking groove is formed.
In vorteilhafter Weise sind wenigstens drei in Umfangsrichtung gleichmäßig voneinander beabstandete Stiftelemente vorgesehen.Advantageously, at least three circumferentially equally spaced pin elements are provided.
In einer besonders bevorzugten Ausführungsform weist die Rastnut einen ersten Nutabschnitt auf, welcher im Wesentlichen in axialer Richtung verläuft, und einen zweiten Nutabschnitt auf, welcher im Wesentlichen in Umfangsrichtung verläuft, wobei an einem von dem ersten Nutabschnitt abgewandten Ende des zweiten Nutabschnittes ein Rastabschnitt ausgebildet ist, in dem das zugeordnete Stiftelement einrastet.In a particularly preferred embodiment, the latching groove on a first groove portion which extends substantially in the axial direction, and a second groove portion which extends substantially in the circumferential direction, wherein at a side remote from the first groove portion end of the second groove portion, a latching portion is formed in which the associated pin element engages.
