Description

Die Erfindung betrifft einen Abgasturbolader gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to an exhaust gas turbocharger according to the preamble of patent claim 1.

Aus dem Serienkraftwagenbau sind Verbrennungskraftmaschinen mit einem Ansaugtrakt bekannt, in welchem ein Verdichter eines Abgasturboladers angeordnet ist, um von der Verbrennungskraftmaschine angesaugte Luft zu verdichten. Bei derartigen abgasturboaufgeladenen Verbrennungskraftmaschinen sind häufig Strömungsgeräusche im Fahrzeuginneren wahrzunehmen, die insbesondere durch den Verdichter verursacht werden. Diese Strömungsgeräusche werden bei Abgasturboladern für Kraftwagen durch einen sogenannten Geräuschring am luftseitigen Eingang des Verdichters minimiert, der es ermöglicht, Geräusche eines Frequenzbandes mit hoher Amplitude zu minimieren.Internal combustion engines with an intake tract in which a compressor of an exhaust-gas turbocharger is arranged in order to compress air drawn in by the internal combustion engine are known from mass-produced motor vehicle construction. In such exhaust-gas-fired internal combustion engines, it is often possible to perceive flow noises in the interior of the vehicle, which are caused in particular by the compressor. These flow noises are minimized in exhaust gas turbochargers for motor vehicles by a so-called noise ring on the air side input of the compressor, which makes it possible to minimize noise of a frequency band with high amplitude.

Aus der US 2003/0150671 A1 ist ein Verdichter mit einem Gehäuse bekannt, der ebenso mindestens einen Geräuschring als Geräusch reduzierende Maßnahme aufweist. Auch sind Einrichtungen vorgesehen, die die eingangs erwähnten Strömungsgeräusche mindern sollen, die aber die Komplexität und damit den Fertigungs- sowie den Montageaufwand des Verdichters ansteigen lassen, woraus hohe Kosten für den Verdichter resultieren.From the US 2003/0150671 A1 is a compressor with a housing known, which also has at least one noise ring as a noise reducing measure. Also devices are provided which are intended to reduce the flow noise mentioned above, but which can increase the complexity and thus the manufacturing and assembly costs of the compressor, resulting in high costs for the compressor.

Der Stand der Technik zeigt geräuschreduzierende Geräuschringe, die gängig form- oder kraftschlüssig mit dem Verdichtergehäuse verbunden sind.The prior art shows noise-reducing noise rings, which are commonly positively or non-positively connected to the compressor housing.

Im Hinblick auf den Bauraumbedarf bieten diese Verbindungskonzepte den Nachteil, dass diese zusätzlichen Bauraum benötigen.In terms of space requirements, these connection concepts have the disadvantage that they require additional space.

Aufgabe der Erfindung ist es, durch eine nichttriviale stoffschlüssige Verbindung eines schallreduzierenden Bauteils mit einer Luftführung zum Verdichter oder einem luftführenden Kanal des Verdichtergehäuses eines Abgasturboladers einer Kraftmaschine, den Bauraum zu reduzieren.The object of the invention is to reduce the space by a non-trivial integral connection of a sound-reducing component with an air duct to the compressor or an air duct of the compressor housing of an exhaust gas turbocharger an engine.

Diese Aufgabe wird durch den erfindungsgemäßen Abgasturbolader gemäß Anspruch 1 gelöst. Der erfindungsgemäße Abgasturbolader ist vorteilhafterweise geräuscharm.This object is achieved by the exhaust gas turbocharger according to the invention according to claim 1. The exhaust gas turbocharger according to the invention is advantageously silent.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels, sowie anhand der Zeichnungen.Further advantages, features and details of the invention will become apparent from the following description of an embodiment, and with reference to the drawings.
