Abstract

According to the invention, a vibration surpressor (6) and a vibration damper (7) are installed in a system consisting of an internal combustion engine and an exhaust-gas turbo charger. The vibration surpressor and vibration damper are secured to an exposed place on the system which is subjected to strong vibrations. As the vibrations are the stongest in said area, the vibration-reducing means can be used to a maximum. The system consisting of the internal combustion engine and the exhaust-gas charger is improved in such a manner that the internal combustion engine can be operated in all of the rotational speed ranges without reducing the service life of individual components or the entire system.

Technisches GebietTechnical field
Die Erfindung bezieht sich auf das Gebiet der aufgeladenen Verbrennungsmotoren. Sie betrifft eine Vorrichtung zum Reduzieren von Schwingungen an einem System aus einem Verbrennungsmotor und einer Aufladevorrichtung, eine Aufladevorrichtung zum Aufladen eines Verbrennungsmotors und ein System aus einem Verbrennungsmotor und einer Aufladevorrichtung.The invention relates to the field of supercharged internal combustion engines. It relates to a device for reducing vibrations in a system comprising an internal combustion engine and a charging device, a charging device for charging an internal combustion engine and a system comprising an internal combustion engine and a charging device.
Stand der Technik Systeme aus Verbrennungsmotor und Aufladevorrichtung, beispielsweisePRIOR ART Systems comprising an internal combustion engine and a charging device, for example
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. Bei Motoren mit konstanter Drehzahl kann die Resonanz durch Verändern derExhaust gas turbochargers, depending on their type of installation, have structure frequencies that are excited by the ignition frequency of the engine and / or the multiple of the nominal speed of the engine. If there are such resonances in the operating range of the engine, the engine with the exhaust gas turbocharger can vibrate to an unacceptably high degree. For motors with constant speed, the resonance can be changed by changing the
Systemsteifigkeit bzw. der Struktureigenfrequenz von der Drehzahl weg geschoben werden. Auf Motoren mit variabler Drehzahl hingegen können mehrere Resonanzen im vorgesehenen Betriebsbereich liegen. Dann treten oft hohe Vibrationen auf, die zu einer Verringerung der Standzeit einzelner Bauteile oder des ganzen Systems führen können. 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.System rigidity or the structure's natural frequency can be pushed away from the speed. On the other hand, on motors with variable speed, there can be several resonances in the intended operating range. Then high vibrations often occur, which can lead to a reduction in the service life of individual components or the entire system. In order to meet the high requirements of end customers and classification societies, certain vibration limit values on the engine block and on the exhaust gas turbocharger must be observed. If it is not possible to fall below the vibration limit values of the manufacturers or classification societies over the entire speed range by changing the natural frequencies, certain speed ranges of the engine must be blocked for operation in order to avoid damage. This inevitably results in disadvantages for the operator. So far no constructive remedial measures known and investigated to effectively reduce the vibrations.
Kurze Darstellung der ErfindungBrief description of the invention
Der Erfindung liegt folglich die Aufgabe zugrunde, ein System aus Verbrennungsmotor und Aufladevorrichtung 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 based on the object of providing a system comprising an internal combustion engine and a charging device, in which the internal combustion engine can be operated in the entire available speed range, without reducing the service life of individual components or of the entire system as a result of vibrations which occur.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass dem System aus Verbrennungsmotor und Aufladevorrichtung Schwingungsreduzierende Mittel, etwa in der Form eines Schwingungstilgers und eines Schwingungsdämpfers, hinzugefügt werden.According to the invention, this object is achieved in that vibration-reducing agents, for example in the form of a vibration absorber and a vibration damper, are added to the system comprising the internal combustion engine and the charging device.
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.The vibration damper and / or the vibration damper is advantageously attached to an exposed, strongly vibrating point of the system. Because the vibrations are strongest there and thus the vibration-reducing agents can be used most effectively.
Da die Aufladevorrichtung in der Regel an exponierter Lage am Verbrennungsmotor befestigt ist, ist es besonders wirkungsvoll, die schwingungsreduzierenden Mittel an der Aufladevorrichtung zu befestigen, im Falle eines Abgasturboladers beispielsweise am Filterschalldämpfer lufteintrittsseitig des Verdichtergehäuses. Weitere Vorteile ergeben sich aus den abhängigen Ansprüchen.Since the charging device is generally attached to the internal combustion engine in an exposed position, it is particularly effective to attach the vibration-reducing means to the charging device, in the case of an exhaust gas turbocharger, for example, on the filter silencer on the air inlet side of the compressor housing. Further advantages result from the dependent claims.

Weg zur Ausführung der ErfindungWay of carrying out the invention
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 Aufladevorrichtung wirksam reduziert werden. Mit Aufladevorrichtung ist im vorliegenden Beispiel ein Abgasturbolader gemeint. Alternativ kann dem Verbrennungsmotor aber auch über einen beispielsweise mechanisch oder elektrisch angetriebenen Verdichter Brennluft zugeführt werden. Die in der Folge beschriebenen, Schwingungsdämpfenden Massnahmen können auch auf solche Aufladevorrichtungen angewandt werden.By installing a damped vibration damper or a vibration damper in exposed locations where the vibrations are strongest, the vibrations of the internal combustion engine and the charging device can be effectively reduced. In the present example, a charging device means an exhaust gas turbocharger. Alternatively, combustion air can also be fed to the internal combustion engine via, for example, a mechanically or electrically driven compressor. The vibration-damping measures described below can also be applied to such charging devices.
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.The damper or vibration damper should primarily act in the main direction of vibration of the mode shapes of the lowest natural frequencies of the engine-turbocharger system, i.e. 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. 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. 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 turbocharger is usually attached to a console above the engine or on the front of the engine in an exposed position. Due to this exposed position, it experiences the strongest vibrations and is therefore best suited for the installation of vibration dampers and vibration absorbers. The vibration damper can be designed in different variants, for example as a vibrating mass on a spring. Vibration dampers can be undamped or damped. Weak and undamped vibration absorbers are designed for a specific frequency and act over a small frequency range. Heavily damped vibration absorbers act like dampers over a wide frequency range. The mass of the vibration damper is around 5-10% of the turbocharger weight. This creates a balance 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 Filterschalidämpfer als Tilgermasse genutzt werden, während über die Befestigung des Filterschalldämpfers an dem Verdichtergehäuse eine Dämpfung erzielt werden kann.Damping takes place through the damping properties of the fastening or with a separate damper. Components of the turbocharger can also be used as vibration absorbers or vibration dampers. For example, a decoupled Filter silencers are used as absorber mass, while damping can be achieved by attaching the filter silencer to the compressor housing.
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 stored as a vibrating mass in a space filled with damping, highly viscous liquid (e.g. oil), or it can be made up of a loose bulk material in a corresponding container. This space can be formed in a rigidly attached tank as an additional component in the system of the internal combustion engine and exhaust gas turbocharger, or as an integral part in a housing cavity 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 außenstehendenThe vibration damper is attached to a strongly vibrating part of the turbocharger and with the engine block, console or an external one
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.Attachment point rigidly connected. Depending on the application, the dampers must be designed for 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 absorbers and dampers can be attached to all housings of the turbocharger, the console or to external parts of the engine block. Since the temperatures at the gas inlet or gas outlet are high and the parts can be damaged, vibration dampers and absorbers should be attached to the bearing housing, compressor housing, filter silencer or, in the case of turbochargers without filter silencer, to the suction nozzle. The filter silencer itself can also be installed as a vibration damper, whereby damping can be achieved via the connection to the compressor housing.
Fig. 1 zeigt einen Abgasturbolader, wie er auf einen Verbrennungsmotor befestigt wird, wobei in der Abbildung nur die äusseren Gehäuseteile sowie die Anschlussflansche für die Zuleitungen zum Verbrennungsmotor zu sehen sind. Die Luft für den Verbrennungsmotor wird über einen Filterschalldämpfer 5 angesaugt und im Verdichtergehäuse 1 auf das rotierende Verdichterrad geführt. Das Verdichterrad ist an einem Ende einer Welle befestigt, welche im Lagergehäuse 4 drehbar gelagert ist. Am anderen Ende der Welle ist das Turbinenrad befestigt. Das Turbinengehäuse umfasst zwei Teile, das Gaseintrittsgehäuse 2 mit der Zuleitung der heissen Abgase vom Verbrennungsmotor, sowie das Gasaustrittsgehäuse 3 mit dem Auslassflansch zum Anschliessen derFig. 1 shows an exhaust gas turbocharger as it is attached to an internal combustion engine, only the outer housing parts and the connecting flanges for the feed lines to the internal combustion engine being shown in the figure. The air for the internal combustion engine is sucked in via a filter silencer 5 and guided in the compressor housing 1 to the rotating compressor wheel. The compressor wheel is attached to one end of a shaft which is rotatably mounted in the bearing housing 4. The turbine wheel is attached to the other end of the shaft. The turbine housing comprises two parts, the gas inlet housing 2 with the supply of hot exhaust gases from the internal combustion engine, and the gas outlet housing 3 with the outlet flange for connecting the
Auspuffanlage. Je nach Art und Grosse ist der Abgasturbolader, am Lagergehäuse oder an einem Teil des Turbinengehäuses mit dem Verbrennungsmotor verbunden. Hilfsweise kann der Abgasturbolader mit einer zweiten Stütze, etwa im Bereich des Filterschalldämpfers zusätzlich abgestützt sein.Exhaust system. Depending on the type and size, the exhaust gas turbocharger is connected to the internal combustion engine on the bearing housing or on part of the turbine housing. In the alternative, the exhaust gas turbocharger can be additionally supported with a second support, for example in the area of the filter silencer.
Erfindungsgemäss weist der Verbrennungsmotor einen Schwingungstilger 6 auf, welcher am Filterschalldämpfer des Abgasturboladers befestigt ist und dessen Masse beispielsweise in einem Tank in Öl dämpfend und mittels elastischen Elementen federnd gelagert oder als loses Schüttgut in einem Behälter angeordnet ist. Ein solcher Schwingungstilger/ -dämpfer kann auch auf einem anderen Gehäuse des Abgasturboladers befestigt werden oder er kann im Gehäuse des Abgasturboladers integriert angeordnet oder selber ein Teil diese Gehäuses sein. 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.According to the invention, the internal combustion engine has a vibration damper 6, which is attached to the filter muffler of the exhaust gas turbocharger and the mass of which, for example, is damped in oil in a tank and is resiliently mounted by means of elastic elements or is arranged as loose bulk material in a container. Such a vibration damper / damper can also be attached to another housing of the exhaust gas turbocharger, or it can be integrated in the housing of the exhaust gas turbocharger or be part of this housing itself. For example, the vibration damper can be attached to the bearing housing with a first support and to the flange connection between the compressor housing and the filter silencer with a second support. The additional attachment is used to connect the vibration absorber / damper to the turbocharger as stiffly as possible so that the vibrations are transmitted as directly as possible to the vibration absorber.
Rechts unten in Fig. 1 ist ein zusätzlicher Schwingungsdämpfer 7 dargestellt, der fest mit dem Filterschalldämpfer 5 und einer entsprechenden Auflage (z.B. Konsole, Motorblock oder externes Gerüst) verbunden ist. Der zusätzliche Schwingungsdämpfer dämpft den schwingenden Filterschalldämpfer optimal (Stelle mit höchsten Amplituden), insbesondere wenn die Abstützung (8) sehr steif ist.An additional vibration damper 7 is shown at the bottom right in FIG. 1, which is firmly connected to the filter silencer 5 and a corresponding support (e.g. console, engine block or external frame).
