Description
Die vorliegende Erfindung betrifft einen Abgasturbolader für eine Brennkraftmaschine, insbesondere eines Kraftfahrzeugs, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The present invention relates to an exhaust gas turbocharger for an internal combustion engine, in particular a motor vehicle, with the features of the preamble of claim 1.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Abgasturbolader der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie eine vereinfachte Herstellung ermöglicht.The The present invention addresses the problem of for an exhaust gas turbocharger of the type mentioned a to provide improved embodiment, in particular characterized in that it enables a simplified production.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Lagerung des Rotors mit Hilfe von zwei Kegellagern zu realisieren, die entgegengesetzte Konizitäten aufweisen. Ein Kegellager charakterisiert sich durch eine kegelförmige oder konische Lagerfläche. Ein derartiges Kegellager zeichnet sich dadurch aus, dass es sowohl radiale als auch axiale Kräfte aufnehmen kann. Durch die Verwendung von zwei axial voneinander beabstandeten Kegellagern kann die vorgeschlagene Lageranordnung somit eine hinreichende axiale und radiale Lagerung des Rotors realisieren. Die zueinander entgegengesetzt orientierten Konizitäten der beiden verwendeten Kegellager führen dabei für die wirksamen Axialkräfte zu einem geschlossenen Kraftpfad, in dem sich die entgegengesetzt wirkenden Axialkräfte gegenseitig aufheben. Da die hier vorgestellte Lageranordnung grundsätzlich mit den beiden Kegellagern auskommt, ist der Aufwand zur Realisierung vergleichsweise gering. Darüber hinaus haben Kegellager den großen Vorteil, dass sich Herstellungstoleranzen besonders einfach durch axiales Positionieren der miteinander zusammenwirkenden konischen Lagerflächen ausgleichen lassen. Insoweit können grundsätzlich weitere Toleranzbereiche für die Herstellung der einzelnen Komponenten des Turboladers zugelassen werden, was für die Herstellung zu einem Preisvorteil führt.The The invention is based on the general idea of the storage of the To realize rotor with the help of two tapered bearings, the opposite Have conicities. A cone bearing is characterized by a conical or conical bearing surface. Such a tapered bearing is characterized in that it both can absorb radial and axial forces. By the Use of two axially spaced taper bearings can the proposed bearing arrangement thus a sufficient axial and realize radial bearing of the rotor. The opposite to each other oriented conicities of the two tapered bearings used lead thereby for the effective axial forces to a closed power path, in which the opposite cancel axial forces acting on each other. Because the here presented bearing arrangement basically with the two Kegellagern gets along, the effort to implement is comparatively low. In addition, tapered bearings have the great advantage that manufacturing tolerances particularly easy by axial Positioning the cooperating conical bearing surfaces balance out. In that regard, basically further tolerance ranges for the production of the individual Components of the turbocharger will be allowed, what for the production leads to a price advantage.
Entsprechend einer vorteilhaften Ausführungsform können die beiden Kegellager eine gemeinsame Lagerbuchse aufweisen, die den Rotor koaxial umschließt und die dem Rotor zugewandte, konische innere Lagerflächen der beiden Kegellager aufweist. Durch diesen Vorschlag wird ein erhöhter Integrationsgrad erreicht, der die Herstellungskosten senkt.Corresponding an advantageous embodiment, the two conical bearings have a common bearing bush, the Rotor coaxially surrounds and facing the rotor, conical having inner bearing surfaces of the two cone bearings. By this proposal achieves a higher degree of integration, which reduces the production costs.
Entsprechend einer weiteren vorteilhaften Ausführungsform kann die hier vorgestellte Lageranordnung für jedes Kegellager einen drehfest am Rotor angeordneten Konus aufweisen, der jeweils eine vom Rotor abgewandte, konische äußere Lagerfläche des jeweiligen Kegellagers aufweist.Corresponding a further advantageous embodiment, the here presented bearing arrangement for each cone bearing a rotatably on the rotor arranged cone, each one of the Rotor facing away, conical outer bearing surface has the respective cone bearing.
Gemäß einer besonderen Weiterbildung kann nun einer dieser Konusse als integraler Bestandteil einer Welle des Rotors hergestellt sein. Auch hierdurch wird der Integrationsgrad erhöht, was die Herstellungskosten reduziert.According to one special training can now be one of these cones as integral Be made part of a shaft of the rotor. Also by this the degree of integration is increased, which reduces the manufacturing costs reduced.
Ferner ist eine Optimierung durch Verwendung von Distanz- oder Ausgleichsscheiben möglich, die in verschiedenen Dicken bereitgestellt und verwendet werden, um einen Toleranzausgleich zu realisieren.Further is an optimization by using distance or shims possible that provided in different thicknesses and used to realize a tolerance compensation.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Further important features and advantages of the invention will become apparent from the Subclaims, from the drawings and from the associated Description of the figures with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
