Abstract
Description
Die vorliegende Erfindung betrifft ganz allgemein eine Geräuschdämpfungsvorrichtung und betrifft insbesondere eine Geräuschdämpfungsvorrichtung für einen Abgasturbolader gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates generally to a noise attenuation device and more particularly relates to a noise damping device for a Exhaust gas turbocharger according to the preamble of claim 1
Bei einem Abgasturbolader mit ungleicher Anzahl von Turbinenradschaufeln und Leitschaufeln sind laut Resonanzgleichung Anregungsbedingungen gegeben, welche zum Ausfall (Schwingungsbruch) der Turbinenradschaufeln führen können. Bei gleicher Anzahl von Turbinenradschaufeln und Leitschaufeln sind diese ausfallkritischen Resonanzbedingungen nicht relevant.at an exhaust gas turbocharger with unequal number of turbine blades and vanes are excitation conditions according to the resonance equation given, which to the failure (vibration break) of the turbine wheel blades to lead can. With the same number of turbine blades and vanes are these failure-critical resonance conditions are not relevant.
Allerdings tritt bei einer gleichzahligen Anzahl von Turbinenradschaufeln und Leitschaufeln der Nachteil auf, dass der Turbinenraddrehklang (hochfrequentes Geräusch infolge Gaspulsation) erheblich verstärkt wird. Dieser Drehklang wird bevorzugt durch das Gehäuse des Abgasturboladers und durch die daran anschließende Abgasanlage abgestrahlt.Indeed occurs with an equal number of turbine blades and Guide vanes the disadvantage that the turbine wheel spin sound (high-frequency noise as a result of gas pulsation). This rotary sound is preferred by the housing the exhaust gas turbocharger and the adjoining exhaust system radiated.
Aus
der
Allerdings lassen sich mit diesem in der Nähe des Turboladers angeordneten Dämpfer die Geräusche nur unzureichend mindern.Indeed can be with this nearby the turbocharger arranged damper the noises only insufficiently reduce.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Geräuschdämpfungsvorrichtung für einen Abgasturbolader zu schaffen, die eine deutlich bessere Geräuschdämpfung erlaubt.It Therefore, the object of the present invention is a noise damping device for one To provide turbocharger, which allows a much better noise reduction.
Diese Aufgabe wird gelöst durch eine Geräuschdämpfungsvorrichtung mit den Merkmalen des Patentanspruchs 1.These Task is solved by a noise damping device with the features of claim 1.
Demnach zeichnet sich die erfindungsgemäße Geräuschdämpfungsvorrichtung für einen Abgasturbolader mit einem Turbinengehäuse, einer Mehrzahl von Leitschaufeln sowie einem Turbinenrad mit einer Mehrzahl von Turbinenradschaufeln dadurch aus, dass eine Geräuschdämpfungseinrichtung in das Turbinengehäuse in der Nähe des Entstehungsortes der Geräusche direkt integriert ist.Therefore the noise damping device according to the invention is characterized for one Exhaust gas turbocharger with a turbine housing, a plurality of vanes and a turbine wheel having a plurality of turbine blades characterized in that a noise damping device in the turbine housing near the place of origin of the sounds is directly integrated.
Die Integration der Geräuschdämpfungseinrichtung in das Gehäuse des Abgasturboladers erlaubt die Elimination der Geräusche in der direkten Nähe des Entstehungsortes der Geräusche, so dass sich diese über Luft- bzw. Körperschallerscheinungen nicht weiter ausbreiten können.The Integration of the noise damping device in the case the exhaust gas turbocharger allows the elimination of the noise in the immediate vicinity the place of origin of the sounds, so that these are over Airborne or structure-borne sound phenomena can not spread further.
Vorzugsweise ist die Geräuschdämpfungseinrichtung zumindest als eine Resonatorkammer ausgebildet, die in der Wandung des Turbinengehäuses ausgebildet ist.Preferably is the noise damping device at least as a resonator chamber formed in the wall of the turbine housing is trained.
Weiter bevorzugte Weiterbildungen der erfindungsgemäßen Geräuschdämpfungsvorrichtung für einen Abgasturbolader sind der Gegenstand von Unteransprüchen.Further preferred developments of the noise damping device according to the invention for a Exhaust gas turbochargers are the subject of dependent claims.
Die vorstehende Aufgabe, die Merkmale und Vorteile nach der vorliegenden Erfindung können unter Berücksichtigung der folgenden, detaillierten Beschreibung der bevorzugten Ausführungsformen der vorliegenden Erfindung und unter Bezugnahme auf die zugehörigen Zeichnungen besser verstanden werden.The above object, the features and advantages of the present invention Invention can considering the following detailed description of the preferred embodiments of the present invention and with reference to the accompanying drawings to be better understood.
Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt einen Abgasturbolader im Teilquerschnitt, bei dem eine erfindungsgemäße Geräuschdämpfungsvorrichtung in Form einer Resonatorkammer vorgesehen ist.The The invention will be explained in more detail below with reference to the drawing. These shows an exhaust gas turbocharger in the partial cross section, in which a noise damping device according to the invention is provided in the form of a resonator chamber.
