Description

Die Erfindung betrifft einen Turbolader gemäß dem Oberbegriff des Anspruches 1.The invention relates to a turbocharger according to the preamble of claim 1.

Ein derartiger Turbolader ist aus der EP 1 398 463 A1 bekannt. Bei diesem Turbolader ist um dessen Welle herum auf der Turbinenseite ein Hitzeschild vorgesehen, der dazu dient, das Lagergehäuse vor Beschädigungen durch überhöhte Temperaturen aufgrund der durch die Turbine strömenden Abgase des Verbrennungsmotors zu schützen. Der bekannte Hitzeschild besteht aus einem einlagigen Bauteil, dessen Wärmedämmeigenschaften jedoch verbesserungsbedürftig sind.Such a turbocharger is known from EP 1 398 463 A1. In this turbocharger, a heat shield is provided around its shaft on the turbine side, which serves to protect the bearing housing from damage due to excessive temperatures due to the flowing through the turbine exhaust gases of the engine. The known heat shield consists of a single-layer component, the thermal insulation properties, however, are in need of improvement.

In der EP 0 160 460 B1 ist eine weitere Anordnung dargestellt, wobei hier eine Scheibenfeder zum Einsatz kommt, die eine axiale Vorspannkraft auf den axial zu fixierenden Schaufellagerring ausübt. Die Funktion der Wärmedämmung ist aufgrund der Turbinenradferne an dieser Stelle nicht gefordert.A further arrangement is shown in EP 0 160 460 B1, in which case a disc spring is used, which exerts an axial preloading force on the blade bearing ring to be fixed axially. The function of the thermal insulation is not required at this point due to the Turbinenradferne.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Turbolader der im Oberbegriff des Anspruches 1 angegebenen Art zu schaffen, der zum einen mittels Scheibenfeder eine axiale Fixierung der Kartusche der variablen Turbinengeometrie in Turbinenradnähe gewährleistet und zum anderen mittels Hitzeschild eine verbesserte Wärmedämmung in Richtung des Lagergehäuses ermöglicht.It is therefore an object of the present invention to provide a turbocharger specified in the preamble of claim 1, which ensures an axial fixation of the cartridge of variable turbine geometry in Turbinenradnähe on the one hand by means of disc spring and on the other hand by means of heat shield allows improved thermal insulation in the direction of the bearing housing ,

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.The solution of this object is achieved by the features of claim 1.

Die Scheibenfeder des erfindungsgemäßen Turboladers ist aus zumindest zwei, gegebenenfalls jedoch mehreren Materiallagen ausgebildet und beinhaltet sowohl die Funktion der Vorspannkrafterzeugung als auch die Verbesserung der Abschirmfunktion durch Erhöhung des Wärmewiderstandes. Dadurch ist es möglich, die Funktion, insbesondere auch bei erhöhten Abgastemperaturen, sicherzustellen.The disc spring of the turbocharger according to the invention is formed of at least two, but optionally several layers of material and includes both the function of Vorspannkrafterzeugung and the improvement of the shielding function by increasing the thermal resistance. This makes it possible to ensure the function, especially at elevated exhaust gas temperatures.

Zusätzlich kann u. U. vorteilhafterweise auf eine Flüssigkeitskühlung des Lagergehäuses verzichtet werden.In addition, u. U. advantageously be dispensed liquid cooling of the bearing housing.

Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The dependent claims have advantageous developments of the invention to the content.

Durch das Vorsehen mehrerer Materiallagen wird es möglich, zur weiteren Verbesserung der Vorspannkraft- und/oder der Wärmedämmeigenschaften zwischen den Materiallagen einen Luftspalt vorzusehen.By providing a plurality of layers of material, it is possible to provide an air gap for further improving the preload force and / or thermal insulation properties between the layers of material.

Hierzu ist es vorzugsweise möglich, eine der Materiallagen topfartig bzw. topfähnlich mit einem erhöhten umlaufenden Rand auszubilden, während die andere Materiallage vorzugsweise als ebene Scheibe ausgebildet ist.For this purpose, it is preferably possible to form one of the material layers pot-like or pot-like with a raised peripheral edge, while the other material layer is preferably formed as a flat disc.

Die Materiallagen können sowohl ein einstückiges Teil bilden wie auch zwei separate Teile, die im Montagezustand aufeinander aufliegen.The material layers can form both an integral part as well as two separate parts which rest on one another in the assembled state.

Ferner ist es grundsätzlich möglich, dass die Materiallagen aus demselben Material bestehen oder dass unterschiedliche Materialien gewählt werden.Furthermore, it is basically possible that the material layers consist of the same material or that different materials are chosen.

In Anspruch 10 ist ein Hitzeschild für einen erfindungsgemäßen Turbolader als selbständig handelbares Objekt definiert.In claim 10, a heat shield for a turbocharger according to the invention is defined as an independently tradeable object.

Fig. 2
a sectional view of a first embodiment of the disc spring according to the invention, and
Fig. 3
one of Fig. 2 corresponding representation of a second embodiment of the disc spring according to the invention.

In Fig. 1 ist ein Teilbereich eines erfindungsgemäßen Turboladers 1 dargestellt, da diese Darstellung für die Erläuterung der erfindungsgemäßen Prinzipien ausreichend ist. Natürlich weist der Turbolader 1 sämtliche üblicherweise vorgesehenen Konstruktionselemente auf, die, wie gesagt, in Fig. 1 jedoch zur Vereinfachung der Darstellung weggelassen sind.In Fig. 1, a portion of a turbocharger 1 according to the invention is shown, since this representation is sufficient for the explanation of the principles of the invention. Of course, the turbocharger 1 has all conventionally provided structural elements, which, as stated, are omitted in Fig. 1, however, for simplicity of illustration.

Somit ist in Fig. 1 ein Turbinengehäuse 2 einer Turbine dargestellt, das benachbart zu einem Lagergehäuse 3 angeordnet ist. Dieses Lagergehäuse 3 ist zwischen dem Turbinengehäuse 2 und einem Verdichtergehäuse (nicht dargestellt) eines ebenfalls nicht gezeichneten Verdichterrades angeordnet. Das Lagergehäuse 3 weist die Lagerung für eine Welle auf, die in Fig. 1 durch die strichpunktierte Mittellinie W symbolisiert ist, da Fig. 1 nur den oberen Teilbereich des erfindungsgemäßen Turboladers 1 wiedergibt.Thus, in Fig. 1, a turbine housing 2 of a turbine is shown, which is arranged adjacent to a bearing housing 3. This bearing housing 3 is arranged between the turbine housing 2 and a compressor housing (not shown) of a likewise not shown compressor wheel. The bearing housing 3 has the bearing for a shaft, which is symbolized in Fig. 1 by the dash-dotted center line W, since Fig. 1 shows only the upper portion of the turbocharger 1 according to the invention.

Die Welle W trägt die Turbine und das Verdichterrad und ist über eine geeignete Lageranordnung im Lagergehäuse 3 gelagert.The shaft W carries the turbine and the compressor wheel and is mounted in the bearing housing 3 via a suitable bearing arrangement.

Zwischen dem Lagergehäuse 3 und einer Kartusche K, die von einer VTG Scheibe 12 mit axialem Anschlag 14 und einem Schaufellagerring 15 gebildet wird und die in dem Turbinengehäuse 2 axial verschieblich angeordnet ist, ist eine erfindungsgemäße Scheibenfeder 4 eingespannt, die mehrlagig ausgebildet ist. Im Beispielsfalle sind hier zwei Materiallagen 5 und 6 vorgesehen, die nachfolgend anhand der Fig. 2 und 3 näher erläutert werden.Between the bearing housing 3 and a cartridge K, which is formed by a VTG disc 12 with axial stop 14 and a blade bearing ring 15 and which is arranged axially displaceably in the turbine housing 2, a disc spring 4 according to the invention is clamped, which is formed in multiple layers. In the example case, two material layers 5 and 6 are provided here, which are explained in more detail below with reference to FIGS. 2 and 3.

Fig. 1 verdeutlicht die Anordnung der Scheibenfeder 4 zwischen dem Turbinengehäuse 2 und dem Lagergehäuse 3, wobei sich aufgrund des abgestuften Aufbaues der Scheibenfeder 4 zwei Abstützbereiche 10, 11 ergeben, mit denen sich die Scheibenfeder, wie im Einzelnen der Fig. 1 entnehmbar ist, an den entsprechenden Teilen des Turbinengehäuses 2 bzw. der Kartusche der variablen Turbinengeometrie und des Lagergehäuses 3 abstützt.1 illustrates the arrangement of the disc spring 4 between the turbine housing 2 and the bearing housing 3, wherein due to the stepped structure of the disc spring 4, two support regions 10, 11 result, with which the disc spring, as shown in detail in FIG. 1 can be removed, is supported on the corresponding parts of the turbine housing 2 and the cartridge of the variable turbine geometry and the bearing housing 3.

In Fig. 2 ist eine erste Ausführungsform der erfindungsgemäßen Scheibenfeder 4 dargestellt. Die beiden Materiallagen 5 und 6 sind bei dieser Ausführungsform einstückig miteinander verbunden, so dass sich ein einheitliches Teil ergibt. Fig. 2 verdeutlicht, dass die Materiallage 5, die die axiale Vorspannkraft aufbringt, eine topfähnliche Ausgestaltung mit einem umlaufenden erhöhten Rand 13 aufweist. Ferner weist die Materiallage 5 eine Mittelausnehmung 9 auf, die koaxial zu einer Mittelausnehmung 8 der Materiallage 6, die als Hitzeschild für die Materiallage 5 dient, angeordnet ist, jedoch einen gleich großen oder größeren Durchmesser hat. Zwischen den Materiallagen 5 und 6 ist ein Luftspalt 7 vorgesehen, der die Wärmedämmeigenschaften weiter verbessert.In Fig. 2, a first embodiment of the disc spring 4 according to the invention is shown. The two layers of material 5 and 6 are integrally connected to each other in this embodiment, so that there is a uniform part. Fig. 2 illustrates that the material layer 5, which applies the axial biasing force, a pot-like configuration with a circumferential raised edge 13 has. Furthermore, the material layer 5 has a central recess 9, which is arranged coaxially to a central recess 8 of the material layer 6, which serves as a heat shield for the material layer 5, but has an equal or larger diameter. Between the layers of material 5 and 6, an air gap 7 is provided, which further improves the thermal insulation properties.

In Fig. 3 ist eine alternative Ausführungsform der Scheibenfeder dargestellt, die in dieser Figur mit der Bezugsziffer 4' in ihrer Gesamtheit bezeichnet ist. Alle übrigen einander entsprechenden Teile sind mit den gleichen Bezugsziffern wie in Fig. 2 versehen.In Fig. 3, an alternative embodiment of the disc spring is shown, which is designated in this figure by the reference numeral 4 'in their entirety. All other corresponding parts are provided with the same reference numerals as in Fig. 2.

Im Unterschied zur Ausführungsform gemäß Fig. 2 sind hier die Materiallagen 5 und 6 separate getrennte Teile, die in Fig. 3 im Montagezustand, also in aufeinander aufliegender Stellung dargestellt sind. Ansonsten kann auf die Beschreibung zu Fig. 2 verwiesen werden.In contrast to the embodiment according to FIG. 2, here the material layers 5 and 6 are separate separate parts, which are shown in FIG. 3 in the assembled state, ie in a superimposed position. Otherwise, reference may be made to the description of FIG. 2.

Wie die Zusammenschau der Fig. 2 und 3 verdeutlicht, ist die Materiallage 6 in beiden Fällen eine ebene Scheibe.As the synopsis of Figs. 2 and 3 illustrates, the material layer 6 is a flat disc in both cases.
