Abstract
Description
Die Erfindung betrifft einen Abgasturbolader für einen Energiewandler gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to an exhaust gas turbocharger for an energy converter according to the preamble of patent claim 1.
Derartige Abgasturbolader für einen Energiewandler sind aus dem allgemeinen Stand der Technik hinlänglich bekannt.
Der Abgasturbolader
Durch die Verwendung der Luftlagereinrichtung
Während des Betriebs des Energiewandlers entsteht ein Abgas des Energiewandlers. Bei diesem Abgas handelt es sich im Falle der Brennstoffzelle um Luft, welche üblicherweise auch als Abluft bezeichnet wird. Das Abgas wird dem Turbinenrad
Der Abgasturbolader
Mit der Welle ist zumindest in axialer Richtung eine Übertragungseinrichtung
Ein Abgasturbolader mit einer axialen Luftlagerung ist beispielsweise der
Der Einsatz der Übertragungseinrichtung
Es ist daher Aufgabe der vorliegenden Erfindung, einen Abgasturbolader der eingangs genannten Art zu schaffen, welcher besonders geringe Herstellkosten aufweist.It is therefore an object of the present invention to provide an exhaust gas turbocharger of the type mentioned, which has particularly low production costs.
Diese Aufgabe wird durch einen Abgasturbolader für einen Energiewandler mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben. This object is achieved by an exhaust gas turbocharger for an energy converter having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Um einen Abgasturbolader für einen Energiewandler der im Oberbegriff des Patentanspruchs 1 angegebenen Art zu schaffen, welcher besonders geringe Herstellkosten aufweist, ist es erfindungsgemäß vorgesehen, dass die Übertragungseinrichtung in die jeweiligen Laufradrücken integriert ist. Die axialen Rotorkräfte des Abgasturboladers werden somit über die Laufradrücken, d. h. über jeweilige, einander zugewandte Rückseiten des Turbinenrads und des Verdichterrads in axiale Luftlager der Luftleiteinrichtung eingeprägt, ohne dass die Verwendung eines zusätzlichen Übertragungselements wie beispielsweise einer mit der Welle gekoppelten Scheibe vorgesehen oder erforderlich ist. Somit können auch die eingangs erwähnte, zeit- und kostenaufwändige Montage der Axialdruck-Scheibe sowie für deren Montage vorgesehen Bauteile wie Gehäuseteile des Abgasturboladers entfallen. Zudem wird der erwähnte Fertigungsschritt des axialen Ausdistanzierens erheblich vereinfacht.In order to provide an exhaust gas turbocharger for an energy converter of the type specified in the preamble of patent claim 1, which has particularly low production costs, it is inventively provided that the transmission device is integrated into the respective impeller back. The axial rotor forces of the exhaust gas turbocharger are thus on the impeller back, d. H. impressed on respective, mutually facing rear sides of the turbine wheel and the compressor wheel in axial air bearings of the louver, without the use of an additional transmission element such as a shaft coupled to the disk is provided or required. Thus, the above-mentioned, time-consuming and costly installation of Axialdruck-disc and provided for mounting components such as housing parts of the exhaust gas turbocharger omitted. In addition, the aforementioned production step of the axial Ausdistanzierens is considerably simplified.
Bei dem Abgasturbolader werden die jeweiligen Laufradrücken als Teil der Axiallagerung genutzt, so dass auch der Bauraumbedarf des Abgasturboladers, insbesondere in axialer Richtung, besonders gering gehalten werden kann.In the exhaust gas turbocharger, the respective impeller backs are used as part of the axial bearing, so that the space requirement of the exhaust gas turbocharger, especially in the axial direction, can be kept particularly low.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung. Die vorstehend in der Beschreibung genannten Merkmale und Merkmalskombinationen sowie die nachfolgend in der Figurenbeschreibung genannten und/oder in den Figuren alleine gezeigten Merkmale und Merkmalskombinationen sind nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar, ohne den Rahmen der Erfindung zu verlassen.Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.
