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-A-0 226 444 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 Leitschaufelverstelleinrichtung for a turbocharger with variable turbine geometry. Vane adjustment devices serve to adapt the supercharger characteristic to the exhaust gas volume flow. Such an adjustment device is known from EP-A-0 226 444. There, the centering of the adjusting ring via rollers, which are mounted by means of thru axles in the guide blade carrier plate. This guide is expensive to manufacture and in the assembly.

Die Erfindung beschäftigt sich daher mit dem Problem, einen Verstellring einer Leitschaufelverstelleinrichtung auf einfache Weise radial zu führen.The invention therefore deals with the problem of radially guiding an adjusting ring of a Leitschaufelverstelleinrichtung in a simple manner.

Dieses Problem wird bei gattungsgemäßen Leitschaufelverstelleinrichtungen gelöst durch das kennzeichnende Merkmal des Anspruchs 1.This problem is solved in generic Leitschaufelverstelleinrichtungen by the characterizing 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 Leitschaufelverstelleinrichtung should also be transported as a module and installed in a housing of an exhaust gas turbine.

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 Ma-terial die Nasen am Verstellring bildet, also die Aussparungen und die Nasen in einem Arbeitsgang hergestellt werden.The formation of the formed on the adjusting lugs in the region of the recesses for receiving the lever ends can be advantageously carried out by the fact that in the manufacture of the recesses, for example by embossing, the displaced Ma material forms the noses on the adjusting ring, so the recesses and the noses are produced in one operation.

Die Eindrehung gemäß Anspruch 3 kann auch als Nut ausgeführt sein.The recess according to claim 3 can also be designed as a groove.

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.Advantageously, the recess of the guide blade carrier plate in the region of the contact points of the lugs is designed to be spherical, so that there is a punctiform contact of the adjusting ring on the guide blade carrier plate.

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 is to be designed so that the adjusting ring in all operating states has axial and radial clearance, so can not jam on the guide vane support plate.

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 will be explained in more detail below with reference to an embodiment. It shows:
Fig. 1
a Leitschaufelverstelleinrichtung invention with schematically illustrated turbine housing before assembly
Fig. 2
the assembled Leitschaufelverstelleinrichtung.

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 vane levers 3 show bores 4 for receiving the ends of vanes axes 5, which are connected to vanes 6. The guide blade axes 5 are mounted in bores 9 in a guide blade carrier plate 7, which is screwed to the housing part 8 (screws not shown).

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 has in the axial direction to the housing projecting lugs 10, which guide the adjusting ring on a recess 11 of the vane support 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 blade axes 5 are welded, soldered or riveted to the guide blade levers 3.

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 Leitschaufelträgerplatte, vanes, levers and adjusting ring can therefore be advantageously produced as a module, transported and installed, the items are connected to the Leitschaufelträgerplatte captive after connecting Leitschaufelachsen and Leitschaufelhebeln.
