Description
Die Erfindung betrifft einen Abgasturbolader mit variabler Turbinengeometrie einer Brennkraftmaschine, insbesondere eines Kraftfahrzeuges, mit einem Turbinengehäuse, einem Lagergehäuse, an einem Leitschaufelträger schwenkbar angeordneten Leitschaufeln einer Turbine, denen jeweils ein Verstellhebel zugeordnet ist, und mit einem Verstellring, welcher mit den Verstellhebeln zusammen wirkt und durch Drehung relativ zum Leitschaufelträger eine Winkelstellung der Leitschaufeln relativ zu einer Strömungsrichtung kollektiv für alle Leitschaufeln verstellt, wobei der Verstellring an seiner radialen Innenfläche mittels einer Gleitlagerung radial geführt ist, gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an exhaust gas turbocharger with variable turbine geometry an internal combustion engine, in particular a motor vehicle, with a turbine housing, a bearing housing, on a vane carrier pivotally arranged vanes of a turbine, each of which an adjusting lever is assigned, and with an adjusting ring, which interacts with the adjusting levers and relative rotation to the vane carrier an angular position of the vanes relative to a flow direction collectively for adjusted all the vanes, wherein the adjusting ring at its radial palm is guided radially by means of a sliding bearing, according to the preamble of claim 1
Der Erfindung liegt die Aufgabe zugrunde, einen Aufbau und eine Montage eines Abgasturboladers zu vereinfachen.Of the Invention is based on the object, a structure and a mounting to simplify an exhaust gas turbocharger.
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.These The object is achieved by a Exhaust gas turbocharger of the o.g. Type with the characterized in claim 1 Characteristics solved. Advantageous embodiments of the invention are in the other claims described.
Dazu ist es bei einem Abgasturbolader der o.g. Art erfindungsgemäß vorgesehen, dass an dem Lagergehäuse eine erste Gleitfläche ausgebildet ist, welche den Verstellring an einer dem Leitschaufelträger abgewandten Seite axial führt.To it is in an exhaust gas turbocharger the o.g. Art provided according to the invention, that on the bearing housing a first sliding surface is formed, which faces away from the adjusting ring on a the guide vane carrier Side axially leads.
Dies hat den Vorteil, dass die Funktion der axiale Gleitlagerung in das Lagergehäuse integriert ist, so dass sich durch diese Funktionsintegration eine Bauteilreduzierung mit entsprechend vereinfachter Montage ergibt.This has the advantage that the function of the axial sliding bearing in the bearing housing is integrated so that through this functional integration a Component reduction with correspondingly simplified assembly results.
In einer bevorzugten Ausführungsform ist die erste Gleitfläche auf wenigstens einer axialen Erhebung des Lagergehäuses ausgebildet.In a preferred embodiment is the first sliding surface formed on at least one axial elevation of the bearing housing.
Eine beidseitige axiale Lagerung des Verstellringes erzielt man dadurch, dass an dem Turbinengehäuse eine zweite Gleitfläche ausgebildet ist, welche den Verstellring an einer dem Leitschaufelträger zugewandten Seite axial führt.A axial bearing of the adjusting ring on both sides is achieved by that on the turbine housing a second sliding surface is formed, which faces the adjusting ring on a the guide vane carrier Side axially leads.
Dadurch, dass der Leitschaufelträger an einem axialen Ende über eine vorbestimmte axiale Breite einen stufenförmigen Absatz mit reduziertem Außendurchmesser aufweist, welcher derart kleiner ist als ein Innendurchmesser der radialen Innenfläche des Verstellringes, dass dieser Absatz die radiale Gleitlagerung des Verstellringes ausbildet, ist die radiale Gleitlagerung mit durch die Stufenform einseitiger axialer Führung für den Verstellring in den Leitschaufelträger integriert, so dass sich durch diese Funktionsintegration eine Bauteilreduzierung mit entsprechend vereinfachter Montage ergibt.Thereby, that the vane carrier at one axial end over a predetermined axial width of a stepped shoulder with reduced outer diameter which is smaller than an inner diameter of the radial inner surface of the adjusting ring, that this paragraph the radial plain bearing forms the adjusting ring, the radial sliding bearing with integrated by the step shape of one-sided axial guidance for the adjusting ring in the guide vane carrier, so that through this functional integration a component reduction with correspondingly simplified assembly results.
Zweckmäßigerweise ist die axiale Breite des Absatzes kleiner als eine axiale Breite des Verstellringes.Conveniently, the axial width of the shoulder is smaller than an axial width the adjusting ring.
In einer besonders bevorzugten Ausführungsform weist der Verstellring mehrere sich von seiner radialen Innenfläche radial nach innen erhebende radiale Führungsnasen, die in Umfangsrichtung voneinander beabstandete angeordnet sind, derart auf, dass die Führungsnasen radial auf dem Absatz des Leitschaufelträgers aufliegen und jeweilige Gleitlager ausbilden.In a particularly preferred embodiment the adjusting ring has several radially from its radial inner surface inwardly elevating radial guide tabs, which are arranged spaced apart in the circumferential direction, in such a way on that the guide noses rest radially on the shoulder of the vane support and respective Training plain bearings.
