Hierzu weist der Verstellring (1) in Axialrichtung vorstehende Nasen (10) auf, die eine Radialführung des Verstellrings (1) auf der Leitschaufelträgerplatte (7) bewirken. <IMAGE>In the case of a guide vane adjustment device for a turbocharger, the adjustment ring (1) is guided on the guide vane carrier plate (7). For this purpose, the adjusting ring (1) has lugs (10) projecting in the axial direction, which bring about a radial guidance of the adjusting ring (1) on the guide vane carrier plate (7). <IMAGE>

Description

Die Erfindung betrifft eine Leitschaufelverstelleinrichtung für einen Turbolader mit variabler Turbinengeometrie. Leitschaufelverstelleinrichtungen dienen dazu, die Ladercharakteristik an den Abgasvolumenstrom anzupassen. Eine derartige Verstelleinrichtung ist aus der EP 226444 bekannt. Dort erfolgt die Zentrierung des Verstellrings über Rollen, die mittels Steckachsen in der Leitschaufelträgerplatte gelagert sind. Diese Führung ist aufwendig in der Herstellung und in der Montage.The invention relates to a guide vane adjustment device for a turbocharger with variable turbine geometry. Leitschaufelverstelleinrichtungen serve the loader characteristics to adapt to the exhaust gas volume flow. Such Adjustment device is known from EP 226444. There the adjustment ring is centered via rollers that stored in the guide vane carrier plate by means of thru axles are. This guide is complex to manufacture and in assembly.

Die Erfindung beschäftigt sich daher mit dem Problem, einen Verstellring einer Leitschaufelverstelleinrichtung auf einfache Weise radial zu führen.The invention is therefore concerned with the problem of a Adjustment ring of a guide vane adjustment device on simple Way to lead radially.

Dieses Problem wird bei gattungsgemäßen Leitschaufelverstelleinrichtungen gelöst durch das kennzeichnende Merkmal des Anspruchs 1.This problem is solved with generic vane adjustment devices solved by the characteristic feature of claim 1.

Ferner soll die neue Leitschaufelverstelleinrichtung auch als Modul transportiert und in ein Gehäuse einer Abgasturbine eingebaut werden können.Furthermore, the new guide vane adjustment device should also transported as a module and in a housing of an exhaust gas turbine can be installed.

Die Ausbildung der am Verstellring angeformten Nasen im Bereich der Aussparungen zur Aufnahme der Hebelenden kann vorteilhaft dadurch erfolgen, daß beim Herstellen der Aussparungen, beispielsweise durch Prägen, das verdrängte Material die Nasen am Verstellring bildet, also die Aussparungen und die Nasen in einem Arbeitsgang hergestellt werden.The formation of the lugs formed on the adjusting ring in the area the recesses for receiving the lever ends can advantageously take place in that when producing the recesses, for example by embossing, the displaced material forms the lugs on the adjustment ring, i.e. the recesses and the noses are made in one operation.

Die Eindrehung gemäß Anspruch 3 kann auch als Nut ausgeführt sein.The insertion according to claim 3 can also be carried out as a groove his.

Vorteilhaft ist die Eindrehung der Leitschaufelträgerplatte im Bereich der Kontaktstellen der Nasen ballig ausgeführt, sodaß sich eine punktförmige Anlage des Verstellrings an der Leitschaufelträgerplatte ergibt.It is advantageous to screw in the guide vane carrier plate spherical in the area of the contact points of the noses, so that there is a point-like contact of the adjusting ring the vane carrier plate results.

Die Dimensionierung der Radialführung und der Axialführung des Verstellrings ist so auszuführen, daß der Verstellring in allen Betriebszuständen axiales und radiales Spiel hat, sich also nicht auf der Leitschaufelträgerplatte verklemmen kann.The dimensioning of the radial guide and the axial guide of the adjusting ring must be designed so that the adjusting ring has axial and radial play in all operating states, do not get stuck on the guide vane carrier plate can.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert. Es zeigt:

Fig. 1
eine erfindungsgemäße Leitschaufelverstelleinrichtung mit schematisch dargestelltem Turbinengehäuse vor dem Zusammenbau
Fig. 2
die zusammengebaute Leitschaufelverstelleinrichtung.
The invention is explained in more detail below using an exemplary embodiment. It shows:
Fig. 1
a guide vane adjusting device according to the invention with a schematically illustrated turbine housing before assembly
Fig. 2
the assembled guide vane adjustment device.

Ein Verstellring 1 weist Ausnehmungen 2 zur Aufnahme der Enden von Leitschaufelhebeln 3 auf. Die Leitschaufelhebel 3 zeigen Bohrungen 4 zur Aufnahme der Enden von Leitschaufelachsen 5, die mit Leitschaufeln 6 verbunden sind. Die Leitschaufelachsen 5 sind in einer Leitschaufelträgerplatte 7, die mit dem Gehäuseteil 8 verschraubt ist (Schrauben nicht dargestellt), in Bohrungen 9 gelagert.An adjusting ring 1 has recesses 2 for receiving the Ends of guide vane levers 3. The guide vane levers 3 show holes 4 for receiving the ends of vane axes 5, which are connected to guide vanes 6. The Guide vane axes 5 are in a guide vane carrier plate 7, which is screwed to the housing part 8 (screws not shown), stored in bores 9.

Der Verstellring 1 weist in Axialrichtung zum Gehäuse hin vorstehende Nasen 10 auf, die den Verstellring auf einer Eindrehung 11 der Leitschaufelträgerplatte radial führen.The adjusting ring 1 points in the axial direction to the housing protruding lugs 10 on the adjustment ring on a Guide the recess 11 of the guide vane carrier plate radially.

Im zusammengebauten Zustand gemäß Fig. 2 sind die Leitschaufelachsen 5 mit den Leitschaufelhebeln 3 verschweißt, verlötet oder vernietet.In the assembled state according to FIG. 2, the guide vane axes are 5 welded to the guide vane levers 3, soldered or riveted.

Die Baueinheit mit Leitschaufelträgerplatte, Leitschaufeln, Hebeln und Verstellring kann daher vorteilhaft als Modul hergestellt, transportiert und eingebaut werden, wobei die Einzelteile nach dem Verbinden von Leitschaufelachsen und Leitschaufelhebeln unverlierbar mit der Leitschaufelträgerplatte verbunden sind.The assembly with guide vane carrier plate, guide vanes, Lever and adjusting ring can therefore be advantageous as a module manufactured, transported and installed, the Individual parts after connecting vane axles and Guide vane levers captive with the guide vane support plate are connected.
