Abstract
Description
Die vorliegende Erfindung betrifft ein Spiralgehäuse, insbesondere ein Turbinen- oder ein Verdichtergehäuse eines Abgasturboladers für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine mit einem derartigen Spiralgehäuse ausgestattete Ladeeinrichtung, insbesondere einen Abgasturbolader.The present invention relates to a spiral housing, in particular a turbine or a compressor housing of an exhaust gas turbocharger for a motor vehicle according to the preamble of claim 1. The invention also relates to a charging device equipped with such a spiral housing, in particular an exhaust gas turbocharger.

Die Auslegung von Zungenelementen in Spiralgehäusen, insbesondere bei Abgasturboladern, richtet sich im Wesentlichen an den Erfordernissen der Gehäusefertigung, in der Regel des Gießprozesses. Hierzu gehören insbesondere ein minimaler Zungenradius sowie eine Lage des Zungenelements zu einem Turbinen- bzw. Verdichterrad. Da das Zungenelement hohe thermische bzw. aerodynamische Belastungen aushalten muss, wird die Widerstandsfähigkeit eines Spiralgehäuses oftmals von der Widerstandsfähigkeit des Zungenelements bestimmt. Um somit ein widerstandsfähiges Spiralgehäuse zu erhalten, muss das Zungenelement – und sofern dieses einteilige mit dem Spiralgehäuse ausgebildet – das gesamte Spiralgehäuse aus einem widerstandsfähigem und dadurch teurem Material ausgebildet werden.The design of tongue elements in spiral housings, in particular in exhaust-gas turbochargers, is essentially based on the requirements of the housing production, as a rule of the casting process. These include in particular a minimum tongue radius and a position of the tongue element to a turbine or compressor wheel. Since the tongue element has to endure high thermal or aerodynamic loads, the resistance of a spiral housing is often determined by the resistance of the tongue element. Thus, to obtain a durable volute casing, the tongue element - and if integral with the volute casing - must form the entire volute casing from a durable and therefore expensive material.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Spiralgehäuse der gattungsgemäßen Art, eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere durch einen erhöhten Verschleißwiderstand und gleichzeitig geringe Herstellkosten auszeichnet.The present invention addresses the problem of providing a spiral housing of the generic type, an improved or at least one alternative embodiment, which is characterized in particular by an increased wear resistance and at the same time low production costs.
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 vorliegende Erfindung beruht auf dem allgemeinen Gedanken, den in einem Spiralgehäuse am höchsten belasteten Bereich separat auszubilden und dadurch vergleichsweise kostengünstig aus einem hochwiderstandsfähigem Material herstellen zu können, wodurch die Widerstandsfähigkeit des gesamten Spiralgehäuses mit vergleichsweise geringen Kosten erhöht werden kann. Der am höchsten in einem Spiralgehäuse belastete Bereich ist der Bereich an einem Zungenelement, so dass dieses erfindungsgemäß separat zum Spiralgehäuse ausgebildet, anschließend fest mit dem Spiralgehäuse verbunden und insbesondere aus einem verschleiß- bzw. widerstandsfähigen Material ausgebildet wird. Das Zungenelement ist dabei an das Spiralgehäuse angepasst und kann in der Art einen Inserts in dieses eingebaut werden. Nach Einbau des Zungenelements ist die geometrische Form der Spirale vollständig ausgebildet. Das Zungenelement bildet somit geometrisch die Zungenkante, die den Belastungen der aerodynamischen Strömung voll ausgesetzt ist. Zu den weiteren Belastungen gehören turbinenseitig auch Temperaturbelastungen und verdichterseitig ein Beschuss durch Kondensat- und/oder Staubpartikel. Mit dem erfindungsgemäß ausgebildeten Zungenelement lassen sich der Verschleißwiderstand und die Widerstandsfähigkeit des gesamten Spiralgehäuses deutlich erhöhen, da das Zungenelement im am höchsten belasteten Bereich angeordnet wird und dadurch bisher eine Schwachstelle bildete. Das Zungenelement kann bspw. mittels eines Sinterprozesses, mittels Schmieden, mittels Strangpressen, mittels Zerspanen oder Umformprozesse hergestellt werden. Insgesamt ist es mit dem erfindungsgemäßen Zungenelement möglich, das Spiralgehäuse an sich aus einem kostengünstigen Werkstoff zu fertigen und ausschließlich den hochbelasteten Zungenbereich durch das gesondert hergestellte Zungenelement zu verstärken. Das vergleichsweise kleine Zungenelement benötigt dabei lediglich eine geringe Menge an teurem Material.The present invention is based on the general idea to separately form the highest loaded in a volute casing area and thereby comparatively inexpensive to produce from a highly resistant material, whereby the resistance of the entire volute casing can be increased with relatively low cost. The region which is subjected to the highest load in a spiral housing is the region on a tongue element, so that according to the invention it is formed separately from the spiral housing, then firmly connected to the spiral housing and in particular formed from a wear-resistant material. The tongue element is adapted to the spiral housing and can be installed in the manner of an insert in this. After installation of the tongue element, the geometric shape of the spiral is completely formed. The tongue element thus forms geometrically the tongue edge, which is fully exposed to the loads of the aerodynamic flow. The other loads also include temperature loads on the turbine side and bombardment by condensate and / or dust particles on the compressor side. With the tongue element designed according to the invention, the wear resistance and the resistance of the entire spiral housing can be markedly increased, since the tongue element is arranged in the region which is subjected to the highest load and thus hitherto constituted a weak point. The tongue element can be produced, for example, by means of a sintering process, by means of forging, by means of extrusion, by means of machining or forming processes. Overall, with the tongue element according to the invention, it is possible to manufacture the spiral housing per se from a cost-effective material and to reinforce exclusively the highly stressed tongue area by the separately produced tongue element. The comparatively small tongue element requires only a small amount of expensive material.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, weist das Zungenelement eine Kanalstruktur auf, welche kommunizierend mit einem Kühlsystem verbunden ist. Da insbesondere auf der Turbinenseite die Temperaturbelastung einen wesentlichen Einfluss auf die Widerstandsfähigkeit des Zungenelements besitzt, kann eine Kühlung desselben die Widerstandsfähigkeit deutlich erhöhen, wodurch die Widerstandsfähigkeit des gesamten Spiralgehäuses an sich gesteigert werden kann. Die Kanalstruktur kann dabei mit der ohnehin in einem Turbinengehäuse bzw. einem Lagergehäuse des Abgasturboladers vorhandenen Kühlkanalstruktur kommunizierend verbunden werden, wodurch lediglich geringe Modifikationen zum Einsatz des erfindungsgemäßen Zungenelements erforderlich sind.In an advantageous development of the solution according to the invention, the tongue element has a channel structure which is communicatively connected to a cooling system. Since, in particular, on the turbine side, the temperature load has a significant influence on the strength of the tongue member, a cooling of the same can significantly increase the resistance, whereby the resistance of the entire volute casing itself can be increased. In this case, the channel structure can be connected in a communicating manner with the cooling channel structure which is present anyway in a turbine housing or a bearing housing of the exhaust gas turbocharger, as a result of which only slight modifications to the use of the tongue element according to the invention are required.
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.
