Description
Die vorliegende Erfindung betrifft eine Ladeeinrichtung, insbesondere einen Abgasturbolader für ein Kraftfahrzeug, gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem einen, mit einer derartigen Ladeeinrichtung ausgestatteten Verbrennungsmotor.The present invention relates to a charging device, in particular an exhaust gas turbocharger for a motor vehicle, according to the preamble of claim 1. The invention also relates to a combustion engine equipped with such a charging device.
In modernen Kraftfahrzeugen werden zunehmend Abgasturbolader mit sogenannten variablen Turbinengeometrien eingesetzt, bei welchen die Leistungsabgabe und das Ansprechverhalten an unterschiedliche Betriebsbedingungen (zum Beispiel Lastwechsel) angepasst werden können. Um das zu erreichen, befinden sich verstellbare, nicht rotierende Leitschaufeln im Turbineneintritt oder im Turbinengehäuse, die üblicherweise zusammen in einem Schaufellagerring gelagert sind.In modern motor vehicles, exhaust gas turbochargers with so-called variable turbine geometries are increasingly used, in which the power output and the response to different operating conditions (for example, load changes) can be adjusted. To achieve this, there are adjustable, non-rotating vanes in the turbine inlet or in the turbine housing, which are usually stored together in a blade bearing ring.

Generell stellt sich bei Ladeeinrichtung mit variablen Turbinengeometrien das Problem, einen minimalen sowie einen maximalen Volumenstrom exakt einstellen zu können. Dafür werden üblicherweise so genannte Zylinderstifte als Endanschläge verwendet. Dabei müssen an den entsprechenden Bauteilen, z. Bsp. an einem Lagergehäuse, Bohrungen für die Zylinderstifte vorgesehen werden, bevor die variable Turbinengeometrie mit dem Lager- und einem Turbinengehäuse montiert wird, was zur Folge hat, dass alle Montagetoleranzen und Fertigungsungenauigkeiten eine negative Auswirkung auf den Mindestabstand der Leitschaufeln zueinander haben. Daneben ist auch die Forderung nach einem Manipulationsschutz der variablen Turbinengeometrie von großer Bedeutung, welcher zur Zeit nur mit großem Aufwand zu realisieren ist. Durch die Manipulation der variablen Turbinengeometrie kann nämlich eine Steigerung der Motorleistung erreicht werden, wobei jedoch stets die Gefahr besteht, dass die Belastung einzelner Komponenten so stark ansteigt, dass die Ladeeinrichtung insgesamt versagt. Bei einem Versagensfall muss jedoch eine entsprechende Manipulation zur Abwehr von Schadensersatzansprüchen nachgewiesen! werden.In general, loading equipment with variable turbine geometries presents the problem of being able to precisely set a minimum as well as a maximum volume flow. Usually so-called cylindrical pins are used as end stops. It must be attached to the corresponding components, eg. For example, on a bearing housing, bores may be provided for the dowel pins before the variable turbine geometry is assembled with the bearing and turbine casings, with the result that all assembly tolerances and manufacturing inaccuracies have a negative effect on the minimum distance of the vanes from one another. In addition, the requirement for a manipulation protection of the variable turbine geometry is of great importance, which is currently only possible with great effort. Namely, by manipulating the variable turbine geometry, an increase in engine output can be achieved, but there is always a risk that the load on individual components increases so much that the charging device fails altogether. In the case of a failure, however, a corresponding manipulation to ward off claims for damages must be proved! become.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Ladeeinrichtung der gattungsgemäßen Art, eine verbesserte Ausführungsform anzugeben, welche insbesondere nur schwer zu manipulieren ist.The present invention addresses the problem of providing a charging device of the generic type, an improved embodiment, which is particularly difficult to manipulate.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einer variablen Turbinengeometrie einer Ladeeinrichtung, an einem Verstellring eine Kontur vorzusehen, welche in zumindest eine leitschaufelträgerseitige oder lagergehäuseseitige Ausnehmung derart eingreift, dass eine Verstellbewegung des Verstellrings relativ zum Leitschaufelträger begrenzt ist. In dem Leitschaufelträger sind dabei üblicherweise drehbar gelagerte Leitschaufeln angeordnet, wobei der Verstellring zur Verstellung der Leitschaufeln dient. Eine Realisierung eines derartigen Endanschlags mittels der verstellringseitigen Konturen, welche in die leitschaufelträgerseitigen oder lagergehäuseseitigen Ausnehmungen eingreifen, bietet den großen Vorteil, dass die üblicherweise großen Montagetoleranzen nunmehr äußerst gering sind, da nur noch zwei Bauteile, nämlich der Verstellring und der Leitschaufelträger, aufeinander abgestimmt werden müssen. Darüber hinaus sind ein derartiger Leitschaufelträger sowie ein zugehöriger Verstellring für eine Vielzahl von Ladeeinrichtungen anwendbar, da keine speziellen Bezüge zu einem Lagergehäuse oder sonstigen Komponenten der Ladeeinrichtung bestehen. Von besonderem Vorteil ist jedoch, dass eine unerwünschte Manipulation der variablen Turbinengeometrie deutlich erschwert und insbesondere auch leichter nachgewiesen werden kann. Zur Manipulation müsste nämlich die gesamte Ladeeinrichtung aus einem Kraftfahrzeug ausgebaut werden, was üblicherweise nicht ohne Demontagespuren, bspw. Kratzspuren, erfolgen kann. Darüber hinaus müsste die Ladeeinrichtung vollständig zerlegt werden, um die Manipulation zu ermöglichen, wobei eine anschließende Montage ohne Spezialwerkzeug und das Fachwissen des Herstellers nicht mehr erfolgen kann. Neben einem deutlich verbreiterten Anwendungsspektrum, welches ebenfalls zu einer Reduzierung der Herstellungskosten führt, können so auch Kostenreduktionen im Bereich geringerer Schadensersatzansprüche realisiert werden. Selbstverständlich kann die Ausnehmung auch in einem Leitschaufelkäfig vorgesehen sein.The invention is based on the general idea, with a variable turbine geometry of a charging device, to provide a contour on an adjusting ring which engages in at least one guide vane-side or bearing-housing-side recess such that an adjusting movement of the adjusting ring is limited relative to the vane carrier. In the guide vane support rotatably mounted vanes are usually arranged, wherein the adjusting serves to adjust the guide vanes. A realization of such an end stop by means of the Verstellringseitigen contours, which engage in the Leitschaufelträgerseitigen or bearing housing side recesses offers the great advantage that the usually large mounting tolerances are now extremely low, since only two components, namely the adjusting ring and the Leitschaufelträger be coordinated have to. In addition, such a vane carrier and an associated adjusting ring for a variety of charging devices are applicable because there are no special references to a bearing housing or other components of the charger. Of particular advantage, however, is that undesired manipulation of the variable turbine geometry is made considerably more difficult and in particular also easier to detect. For manipulation namely the entire charging device would have to be removed from a motor vehicle, which usually can not be done without disassembly traces, for example. Scratch marks. In addition, the loading device would have to be completely disassembled to allow manipulation, with subsequent assembly without special tools and the expertise of the manufacturer can no longer be done. In addition to a significantly broader range of applications, which also leads to a reduction in manufacturing costs, as well as cost reductions in the field of lower claims for damages can be realized. Of course, the recess may also be provided in a guide vane cage.
Erfindungsgemäß ist die wenigstens eine Kontur als in Axialrichtung des Verstellrings abstehende Lasche ausgebildet und mittels eines Stanz- bzw. Umformvorgangs hergestellt. Die Kontur kann demnach zusammen, dass heißt insbesondere gleichzeitig, mit dem Herstellvorgang des Verstellrings erzeugt werden und in einem Arbeitsschritt zusammen mit dem Verstellring hergestellt werden, so dass insbesondere für den Verstellring keine zusätzlichen Fertigungskosten anfallen. Durch die Herstellung der wenigstens einen Kontur mittels eines Stanz-Umformvorgangs, kann die Kontur darüber hinaus äußerst prozesssicher und genau hergestellt werden, ohne dass hierbei Montagetoleranzen eine Rolle spielen. According to the invention, the at least one contour is designed as a tab projecting in the axial direction of the adjusting ring and produced by means of a punching or forming process. Accordingly, the contour can be produced together, ie in particular simultaneously, with the production process of the adjusting ring and can be produced in one working step together with the adjusting ring, so that no additional production costs are incurred, in particular for the adjusting ring. Moreover, by producing the at least one contour by means of a stamping / forming process, the contour can be produced extremely reliably and accurately without the need for assembly tolerances.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description 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 is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
