Abstract
Description
Die Erfindung bezieht sich auf das Gebiet der aufgeladenen Verbrennungsmotoren. Sie betrifft ein System aus einem Verbrennungsmotor und einem Abgasturbolader sowie eine Vorrichtung zum Reduzieren von Schwingungen an einem System aus einem Verbrennungsmotor und einem Abgasturbolader.The invention relates to the field of supercharged internal combustion engines. she relates to a system of an internal combustion engine and an exhaust gas turbocharger and a Device for reducing vibrations on a system from a Internal combustion engine and an exhaust gas turbocharger.
Systeme aus Verbrennungsmotor und Abgasturbolader haben abhängig von ihrer Aufstellungsart Struktureigenfrequenzen, die von der Zündfrequenz des Motors und/ oder den Vielfachen der Nenndrehzahl des Motors angeregt werden. Liegen solche Resonanzen im Betriebsbereich des Motors, kann der Motor mit dem Abgasturbolader unzulässig stark schwingen.Systems of internal combustion engine and turbocharger depend on their Set up structural natural frequencies that depend on the ignition frequency of the engine and / or be excited to multiples of the rated speed of the motor. Are such Resonances in the operating range of the engine, the engine with the exhaust gas turbocharger swing inadmissibly strong.
Bei Motoren mit konstanter Drehzahl kann die Resonanz durch Verändern der Systemsteifigkeit bzw. der Struktureigenfrequenz von der Drehzahl weg geschoben werden. Auf Motoren mit variabler Drehzahl hingegen können mehrere Resonanzen im vorglesehenen Betriebsbereich liegen. Dann treten oft hohe Vibrationen auf, die zu einer Verringerung der Standzeit einzelner Bauteile oder des ganzen Systems führen können.In constant speed motors, the resonance can be changed by changing the System stiffness or the structural natural frequency of the speed pushed away become. On variable speed motors, on the other hand, there are several resonances in the system lying in the operating range. Then often occur high vibrations, which leads to a Reduction of service life of individual components or the whole system can lead.
Um den hohen Anforderungen von Endkunden und Klassifikationsgesellschaften gerecht zu werden, müssen bestimmte Schwingungsgrenzwerte am Motorblock und am Abgasturbolader eingehalten werden. Gelingt es nicht, durch Verändern der Eigenfrequenzen die Schwingungsgrenzwerte der Hersteller oder Klassifikationsgesellschaften über den ganzen Drehzahlbereich zu unterschreiten, müssen gewisse Drehzahlbereicht des Motors für den Betrieb gesperrt werden, um Schäden zu vermeiden. Zwangsläufig ergeben sich dadurch Nachteile für den Betreiber. Bislang sind keine konstruktiven Abhilfemaßnahmen bekannt und untersucht, um die Schwingungen wirksam zu reduzieren. To meet the high demands of end users and classification societies To be sure, certain vibration limits on the engine block and on the Exhaust gas turbocharger are respected. Do not succeed by changing the Natural frequencies the vibration limits of the manufacturer or Classification societies over the whole speed range must fall certain speed range of the motor will be locked for operation to damage avoid. Inevitably, this results in disadvantages for the operator. So far No constructive remedies known and investigated to avoid the vibrations effectively reduce.
Der Erfindung liegt folglich die Aufgabe zugrunde, ein System aus Verbrennungsmotor und Abgasturbolader zu schaffen, in welchem der Verbrennungsmotor in dem gesamten zu Verfügung stehenden Drehzahlbereich betrieben werden kann, ohne durch dabei entstehende Schwingungen die Standzeit einzelner Bauteile oder des ganzen Systems zu verringern.The invention is therefore the object of a system of internal combustion engine and to provide exhaust gas turbocharger in which the internal combustion engine in the whole available speed range can be operated without going through it resulting oscillations the service life of individual components or the whole system reduce.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass dem System aus Verbrennungsmotor und Abgasturbolader schwingungsreduzierende Mittel, etwa in der Form eines Schwingungstilgers und/ oder eines Schwingungsdämpfers, hinzugefügt werden.According to the invention this object is achieved in that the system Internal combustion engine and exhaust gas turbocharger vibration reducing means, such as in Shape of a vibration absorber and / or a vibration damper, added become.
Vorteilhafterweise wird der Schwingungstilger und/oder der Schwingungsdämpfer an einer exponierten, stark schwingenden Stelle des Systems befestigt. Da dort die Schwingungen am stärksten sind und damit die schwingungsreduzierenden Mittel am wirkungsvollsten eingesetzt werden können.Advantageously, the vibration damper and / or the vibration damper on a attached exposed, strongly vibrating point of the system. Because there are the vibrations the strongest and thus the vibration reducing agents are the most effective can be used.
Da der Turbolader in der Regel in exponierter Lage am Verbrennungsmotor befestigt ist, ist es besonders wirkungsvoll, die schwingungsreduzierenden Mittel am Turbolader zu befestigen, beispielsweise am Filterschalldämpfer lufteintrittsseitig des Verdichtergehäuses.Since the turbocharger is usually mounted in an exposed position on the internal combustion engine, It is particularly effective to use the vibration reducing means on the turbocharger attach, for example, on the filter muffler air inlet side of the Compressor housing.
Weitere Vorteile ergeben sich aus den abhängigen Ansprüchen.Further advantages emerge from the dependent claims.

Durch das Anbringen eines gedämpften Schwingungstilgers oder eines Schwingungsdämpfers an exponierten Stellen, an denen die Vibrationen am stärksten sind, können die Schwingungen von Verbrennungsmotor und Abgasturbolader wirksam reduziert werden.By attaching a damped vibration absorber or a Vibration damper in exposed places where the vibrations are strongest are, the vibrations of internal combustion engine and exhaust gas turbocharger can be effective be reduced.
Dabei sollte der Dämpfer oder Schwingungstilger in erster Linie in die Hauptschwingungsrichtung der Eigenformen der tiefsten Eigenfrequenzen des Motor-Turbolader-Systems wirken, d.h. in der Regel in Richtung der Turboladerachse und quer (horizontal) dazu.Here, the damper or vibration absorber in the first place in the Main vibration direction of the eigenmodes of the lowest natural frequencies of the engine turbocharger system act, i. usually in the direction of the turbocharger axis and across (horizontally).
Der Turbolader ist meist auf einer Konsole über dem Motor oder an der Stirnseite des Motors in exponierter Lage befestigt. Durch diese exponierte Lage erfährt er die stärksten Vibrationen und ist deshalb für das Anbringen von Schwingungsdämpfern und Schwingungstilgern am besten geeignet.The turbocharger is usually on a console above the engine or at the front of the engine Motors fixed in exposed position. Through this exposed situation, he experiences the strongest Vibration and is therefore for the attachment of vibration dampers and Most suitable for vibration absorbers.
Der Schwingungstilger kann in verschiedenen Varianten ausgeführt sein, beispielsweise als schwingende Masse an einer Feder. Schwingungstilger können ungedämpft oder gedämpft sein. Schwach- und ungedämpfte Schwingungstilger werden auf eine bestimmte Frequenz ausgelegt und wirken über einen kleinen Frequenzbereich. Stark gedämpfte Schwingungstilger wirken wie Dämpfer über einen breiten Frequenzbereich.The vibration absorber can be designed in different variants, for example as a vibrating mass on a spring. Vibration absorbers can be undamped or be muffled. Weak and undamped vibration absorbers are set to a specific Frequency designed and act over a small frequency range. Heavily steamed Vibration dampers act as dampers over a wide frequency range.
Die Masse des Schwingungstilgers beträgt rund 5- 10% der Turboladergewichts. Auf diese Weise wird eine Ausgewogenheit geschaffen zwischen der zu erreichenden Dämpferkraft und dem Zusatzgewicht, welches der Lader mechanisch ertragen muss.The mass of the vibration absorber is around 5-10% of the turbocharger weight. To this Way, a balance is created between the damper force to be achieved and the additional weight that the loader has to endure mechanically.
Die Dämpfung erfolgt durch die dämpfenden Eigenschaften der Befestigung oder mit separatem Dämpfer. Auch können Bauteile des Turboladers als Schwingungstilger oder Schwingungsdämpfer genutzt werden. Beispielsweise kann ein abgekoppelter Filterschalldämpfer als Tilgermasse genutzt werden, während über die Befestigung des Filterschalldämpfers an dem Verdichtergehäuse eine Dämpfung erzielt werden kann.The damping is achieved by the damping properties of the attachment or with separate damper. Also, components of the turbocharger as a vibration absorber or Vibration dampers are used. For example, a decoupled Filter mufflers are used as absorber mass, while on the attachment of the Filter silencer on the compressor housing damping can be achieved.
Die Tilgermasse kann auch als schwingende Masse in einem mit dämpfender, hochviskoser Flüssigkeit (z.B. Öl) gefüllten Raum gelagert sein, oder aus einem losen Schüttgut bestehend in einem entsprechenden Behälter angeordnet sein. Dieser Raum kann in einem starr befestigten Tank als zusätzliches Bauteil im System aus Verbrennungsmotor und Abgasturbolader, oder als integraler Bestandteil in einem Gehäusehohlraum am Turbolader, der Konsole oder dem Motor ausgebildet sein. The absorber mass can also be used as a vibrating mass in a steaming, highly viscous liquid (e.g., oil) filled space, or loose Bulk material to be arranged in a corresponding container. This room can look like in a rigidly mounted tank as an additional component in the system Internal combustion engine and turbocharger, or as an integral part in one Casing cavity may be formed on the turbocharger, the console or the engine.
Der Schwingungsdämpfer wird an einem stark schwingenden Teil des Turboladers befestigt und mit dem Motorblock, Konsole oder einem außenstehenden Befestigungspunkt starr verbunden. Die Dämpfer müssen abhängig von der Anwendung auf eine relativ hohe Eigenfrequenz (10 -100 Hz) und kleine Schwingungsamplituden (0.1 -2 mm) ausgelegt sein.The vibration damper is attached to a strongly oscillating part of the turbocharger attached and with the engine block, console or an outside Attachment point rigidly connected. The dampers must be dependent on the application to a relatively high natural frequency (10 -100 Hz) and small vibration amplitudes (0.1 -2 mm).
Schwingungstilger und Dämpfer können an allen Gehäusen des Turboladers, der Konsole oder an aussenliegenden Teilen des Motorblocks angebracht sein. Da am Gaseintritt oder Gasaustritt die Temperaturen hoch sind und die Teile Schaden nehmen können, sollten Schwingungsdämpfer und -tilger an Lagergehäuse, Verdichtergehäuse, Filterschalldämpfer oder, bei Turboladern ohne Filterschalldämpfer, am Saugstutzen angebracht werden. Der Filterschalldämpfer selbst kann auch als Schwingungstilger angebaut werden, wobei über die Verbindung zum Verdichtergehäuse eine Dämpfung erreicht werden kann.Vibration damper and damper can be mounted on all housings of the turbocharger, the console or attached to external parts of the engine block. As at the gas inlet or Gas leakage temperatures are high and the parts may damage Vibration damper and silencer to bearing housing, compressor housing, Filter silencer or, in the case of turbochargers without filter silencer, on the intake manifold be attached. The filter silencer itself can also be used as a vibration absorber be grown, wherein via the connection to the compressor housing a damping can be achieved.

Gaseintrittsgehäuse 2 mit der Zuleitung der heissen Abgase vom Verbrennungsmotor,
sowie das Gasaustrittsgehäuse 3 mit dem Auslassflansch zum Anschliessen der
Auspuffanlage. Je nach Art und Grösse ist der Abgasturbolader, am Lagergehäuse oder

Beispielsweise kann der Schwingungstilger mit einer ersten Abstützung am Lagergehäuse
und mit einer zweiten Abstützung auf die Flanschverbindung zwischen dem
Verdichtergehäuse und dem Filterschalldämpfer befestigt sein. Dabei dient die zusätzliche
Befestigung dazu, den Schwingungstilger/ -dämpfer so steif wie möglich mit dem
Turbolader zu verbinden, damit die Schwingungen möglichst direkt auf den
Schwingungstilger übertragen werden.

dem Filterschalldämpfer 5 und einer entsprechenden Auflage (z.B. Konsole, Motorblock
oder externes Gerüst) verbunden ist. Der zusätzliche Schwingungsdämpfer dämpft den
