Description
Die vorliegende Erfindung betrifft eine Ladeeinrichtung, insbesondere einen Abgasturbolader für ein Kraftfahrzeug, mit einer variablen Turbinen- und/oder Verdichtergeometrie gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem ein Verfahren zur Montage einer derartigen Ladeeinrichtung.The The present invention relates to a charging device, in particular an exhaust gas turbocharger for a motor vehicle, with a variable turbine and / or compressor geometry according to the The preamble of claim 1. The invention also relates a method for assembling such a charging device.

Variable Turbinengeometrien bei Ladeeinrichtungen finden zunehmend Verbreitung, da mit ihnen eine Leistung der Ladeeinrichtung flexibel und schnell anpassbar ist. Konstruktiv betrachtet sind derartige variable Turbinengeometrien jedoch zum Teil äußerst aufwendig zu fertigen, was insbesondere in der Tatsache begründet liegt, dass die Leitschaufeln zuerst mit ihrem Schaufellagerzapfen durch einen Schaufellagerring gesteckt und anschließend von der anderen Seite ein Verstellhebel mit dem freien Ende des Schaufellagerzapfens verbunden werden muss. Dieser Verstellhebel greift in korrespondierende Ausnehmungen an einem Verstellring ein und ermöglicht durch ein Verdrehen des Verstellrings ein vorzugsweise simultanes Verstellen sämtlicher Leitschaufeln.variable Turbine geometries in charging facilities are becoming increasingly widespread because with them a performance of the charging device flexible and fast is customizable. Structurally, such variable turbine geometries are However, sometimes extremely expensive to manufacture, which is due in particular to the fact that the vanes first with their shovel journal through a Blade bearing ring inserted and then from the other Side a lever with the free end of the vane journal must be connected. This lever engages in corresponding Recesses on an adjusting ring and allows by a rotation of the adjusting ring preferably a simultaneous adjustment all vanes.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Ladeeinrichtung der gattungsgemäßen Art, eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, welche sich insbesondere durch eine deutlich vereinfachte Montage und eine reduzierte Teileanzahl auszeichnet.The The present invention addresses the problem of for a charging device of the generic type Kind, an improved or at least an alternative embodiment which, in particular, should be clearly simplified Assembly and a reduced number of parts distinguishes.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the objects of the independent claims. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, eine variable Turbinen- und/oder Verdichtergeometrie einer Ladeeinrichtung derart auszubilden, dass sie bezüglich ihrer einzelnen Komponenten, das heißt insbesondere bezüglich eines Schaufellagerrings und daran bzw. darin gelagerten Leitschaufeln und bezüglich eines Verstellrings zum Verstellen der Leitschaufeln, aus lediglich einer axialen Richtung zusammensteckbar und damit montierbar ist. Die einzelnen Leitschaufeln sind dabei vorzugsweise einstückig ausgeführt und weisen demnach nicht wie bisher üblich, separate Verstellhebel auf, die erst in einem zusätzlichen Montageschritt an einem Schaufellagerzapfen der Leitschaufeln befestigt werden müssen. Durch die einstückig ausgebildeten Leitschaufeln kann somit eine deutliche Reduzierung der Teilevielfalt erreicht werden, wodurch insbesondere ein reduzierter Montageaufwand und geringere Lager- und Logistikkosten verbunden sind. Durch die erfindungsgemäße Ausbildung der Turbinen- und/oder Verdichtergeometrie derart, dass sie aus lediglich einer axialen Richtung zusammensteckbar und montierbar ist, wird auch die Montage bzw. eine entsprechende Demontage deutlich vereinfacht, da die variable Turbinen- und/oder Verdichtergeometrie weder bei der Montage noch bei der Demontage verdreht bzw. ausgerichtet werden muss, um bspw. die einzelnen Leitschaufeln zu montieren. Die einstückig ausgebildeten Leitschaufeln ermöglichen ein Einstecken derselben in den Schaufellagerring von einer Seite her, wobei der zugehörige Verstellring zum Verstellen der Leitschaufeln aus derselben axialen Richtung aufgeschoben wird.The Invention is based on the general idea of a variable turbine and / or form compressor geometry of a charging device in such a way that they respect their individual components, that is in particular with respect to a vane bearing ring and thereto or stored therein vanes and with respect to a Adjustment ring for adjusting the vanes, only one axial direction can be plugged together and thus mounted. The individual vanes are preferably in one piece executed and thus do not show as usual, separate adjusting lever, the first in an additional Mounting step are attached to a vane journal of the vanes have to. By integrally formed vanes can thus achieve a significant reduction in the variety of parts be, which in particular a reduced assembly costs and lower storage and logistics costs are associated. By the invention Forming the turbine and / or compressor geometry such that they can be assembled and assembled from only one axial direction is, the assembly or a corresponding disassembly is clear simplified, since the variable turbine and / or compressor geometry neither rotated or aligned during assembly even during disassembly must be, for example, to assemble the individual vanes. The integrally formed guide vanes allow an insertion of the same in the blade bearing ring from one side ago, with the associated adjusting ring for adjusting the Guide vanes is pushed from the same axial direction.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, sind die Leitschaufeln im Metallspritzgussverfahren hergestellt oder aus Keramik ausgebildet. Das Metallpulverspritzgussverfahren erlaubt es, komplizierte und komplexe Geometrien mit ausgezeichneter Maßhaltigkeit und bester Wirtschaftlichkeit, insbesondere bei hohen Stückzahlen herzustellen. Darüber hinaus weisen derartig hergestellte Bauteile nahezu keinen Nachbearbeitungsaufwand auf, wodurch die Fertigung insgesamt kostengünstiger gestaltet werden kann. Als Rohmaterial beim Metallpulverspritzgussverfahren wird Metallpulver mit einem Bindemittel zu einem homogenen, spritzgießfähigen Granulat vermischt. Die anschließende Verarbeitung des Granulats erfolgt auf konventionellen Spritzgießmaschinen zum Grünling. Das Abschließen des Sinterns bei hohen Temperaturen sowie die anschließende Wärmebehandlung erlauben ein vielseitiges Einstellen von mechanischen Eigenschaften, wie bspw. Härte, Festigkeit oder Zähigkeit. Denkbar ist hierbei auch eine alternative Ausbildung der erfindungsgemäßen Leitschaufeln aus Keramik, welche insbesondere mittels Keramikpulverspritzgussverfahren hergestellt werden. Das keramische Spritzgießen bietet dabei ähnliche Vorteile hinsichtlich der Maßgenauigkeit und der Stückkosten, wie das Metallpulverspritzgussverfahren. Darüber hinaus können mittels keramischen Spritzgussverfahren hergestellte Leitschaufeln bei hohen Temperaturen, insbesondere auch bei Ottomotoren, eingesetzt werden.In an advantageous embodiment of the solution according to the invention, the guide vanes are produced in the metal injection molding process or formed of ceramic. The metal powder injection molding process makes it possible to produce complex and complex geometries with excellent dimensional stability and best economy, especially in high volumes. In addition, such manufactured components have almost no reworking effort, whereby the manufacturing can be made more cost-effective overall. As a raw material in the metal powder injection molding process, metal powder is mixed with a binder to a homogeneous, injection-moldable granules. The subsequent processing of the granules is carried out on conventional injection molding machines to green. The completion of the sintering at high temperatures and the subsequent heat treatment allow a versatile adjustment of mechanical properties, such as hardness, strength or toughness. Conceivable here is an alternative Ausbil tion of the guide vanes according to the invention made of ceramic, which are produced in particular by means of ceramic powder injection molding. The ceramic injection molding offers similar advantages in terms of dimensional accuracy and unit costs, such as the metal powder injection molding process. In addition, vanes produced by ceramic injection molding can be used at high temperatures, especially in gasoline engines.
