Definitions

  • 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.
  • Exhaust 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
  • 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.
  • 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.
  • 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.
  • 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.
  • Fig. 1 is a view of an exhaust gas turbocharger with a first embodiment of an inventive device for reducing vibrations
  • Fig. 2 is a view of an exhaust gas turbocharger with a second embodiment of an inventive device for reducing vibrations.
  • a charging device means an exhaust gas turbocharger.
  • 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.
  • 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).
  • 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.
  • 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.
  • a decoupled Filter silencers are used as absorber mass, while damping can be achieved by attaching the filter silencer to the compressor housing.
  • 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.
  • the vibration damper is attached to a strongly vibrating part of the turbocharger and with the engine block, console or an external one
  • the dampers must be designed for a relatively high natural frequency (10-100 Hz) and small vibration amplitudes (0.1-2 mm).
  • 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 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
  • the exhaust gas turbocharger is connected to the internal combustion engine on the bearing housing or on part of the turbine housing.
  • the exhaust gas turbocharger can be additionally supported with a second support, for example in the area of the filter silencer.
  • 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.
  • 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.
  • 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.
  • 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).
  • the additional vibration damper optimally dampens the vibrating filter silencer (point with the highest amplitudes), especially if the support (8) is very stiff.
  • Fig. 2 shows a vibration damper 9 which is attached to the bearing housing. Damping takes place via the material damping of the fastening (multi-layer material with damping intermediate layers) or through a separate vibration damper.

Abstract

Selon l'invention, on installe un réducteur de vibrations (6) et un amortisseur de vibrations (7) sur un système composé d'un moteur à combustion interne et d'un turbocompresseur. Le réducteur de vibrations et l'amortisseur de vibrations sont installés sur une zone exposée du système, soumise à de fortes vibrations. Comme les vibrations sont les plus fortes dans cette zone, l'effet des éléments de réduction des vibrations est maximal. Le système composé du moteur à combustion interne et du turbocompresseur est amélioré du fait que le moteur à combustion interne peut être utilisé dans toute la zone de régime disponible sans que la durée de vie des composants individuels ou de l'ensemble du système n'en soit réduite.
