Description

Die Erfindung betrifft eine Vorrichtung zur Geräuschdämpfung gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a device for noise reduction according to the preamble of the main claim.

Aus der DE-PS 34 44 838 ist bereits eine Vorrichtung zur Ge­ räuschdämpfung der gattungsgemäßen Art mit einer im Kurbelge­ häuse das Triebwerk zur Ölwanne hin abdeckenden Schale bekannt. In der Schale sind mehrere Schlitze angebracht, die die Funk­ tion eines Ölhobels übernehmen.From DE-PS 34 44 838 a device for Ge Noise reduction of the generic type with one in the crank housing known the engine to the oil pan covering shell. There are several slots in the shell that allow the radio tion of an oil slicer.

Ferner wird durch die Schale zurückfließendes Schmieröl aus dem Zylinderkopfbereich an den rotierenden Teilen im Kurbelgehäuse vorbeigeführt.Furthermore, lubricating oil flowing back through the shell is removed from the Cylinder head area on the rotating parts in the crankcase passed by.

Diese Vorrichtungen der bekannten Art können jedoch die verti­ kalen Gasimpulse der unter dem Kolben bewegten Gassäulen nur sehr unvollständig abbauen, da die niederfrequenten Schwin­ gungen durch Strömungsengpässe (Ölhobel) nicht nennenswert in ihrer Amplitude gedämpft werden.However, these devices of the known type can verti Kal gas pulses from the gas columns moving under the piston only degrade very incompletely, since the low-frequency swine due to flow bottlenecks (oil plane) not noteworthy in their amplitude are damped.

Der Erfindung liegt die Aufgabe zugrunde, die Schaltabstrahlung der Ölwanne von Brennkraftmaschinen, insbesondere im nieder­ frequenten Bereich, durch Dämpfung der vertikalen Gasimpulse zu verringern.The invention has for its object the switching radiation the oil pan of internal combustion engines, especially in the low frequency range, by damping the vertical gas pulses too reduce.

Die Aufgabe ist erfindungsgemäß durch die im Kennzeichen des Hauptanspruchs angegebenen Merkmale gelöst. The object is according to the invention in the characteristic of Main claim specified features solved.  

Der Vorteil der erfindungsgemäßen Anordnung der Dämpfungskammer liegt darin, daß eine direkte Beaufschlagung der Ölwanne durch die pulsierenden Geräusche unter dem Kolben vermieden und damit eine geringere Schallabstrahlung der Ölwanne, insbesondere im niederfrequenten Bereich, erreicht wird.The advantage of the arrangement of the damping chamber according to the invention lies in the fact that the oil pan is acted upon directly the pulsating noises under the piston avoided and thus a lower sound radiation from the oil pan, especially in the low-frequency range.

Das Gehäuse zwischen Triebwerk und Ölwanne dient als Dämp­ fungskammer, in der die einzelnen Gasstöße, die von den Kolben herrühren, durch Strömungsausgleich achsparallel zur Kurbel­ welle kompensiert werden. Dadurch erfolgt eine wesentliche Dämpfung des Impulses der Strömung.The housing between the engine and the oil pan serves as a damper chamber in which the individual gas surges by the pistons originate, through flow compensation axially parallel to the crank wave can be compensated. This is an essential one Damping the momentum of the flow.

Weitere Ausgestaltungen und Vorteile der Erfindung gehen aus den Unteransprüchen und der Beschreibung hervor.Further configurations and advantages of the invention go out the subclaims and the description.

Zwei Ausführungsbeispiele sind in den nachfolgenden Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zei­ gen:Two embodiments are in the following drawings are shown and are described in more detail below. It shows gene:

Fig. 1 ein Kurbelgehäuse mit angeflanschten Seitenwänden und Ölwanne und einer erfindungsgemäßen Ausfüh­ rung der Dämpfungskammer, und Fig. 1 is a crankcase with flanged side walls and oil pan and a Ausfüh tion of the damping chamber, and

Fig. 2 einen Teil eines Kurbelgehäuses in einer Ausfüh­ rungsform der Dämpfungskammer für einen Motor mit Ausgleichswelle unter der Kurbelwelle. Fig. 2 shows a part of a crankcase in a Ausfüh approximate shape of the damping chamber for an engine with a balance shaft under the crankshaft.

In Fig. 1 ist ein Kurbelgehäuse 1 eines nicht vollständig dar­ gestellten Kolbenmotors mit einem Zylinder 2, den Seitenwänden 3 und einer Ölwanne 4 dargestellt.In Fig. 1, a crankcase 1 of a piston engine is not fully shown with a cylinder 2 , the side walls 3 and an oil pan 4 is shown.

Im Kurbelgehäuse 1 ist eine Kurbelwelle 5 in Lagern (Lagerdek­ kel 18) gelagert. Die Kurbelwelle 5 und die mit ihr umlaufenden Teile sind durch eine Schale 6 gegenüber der Ölwanne 4 abgedeckt. Die Schale 6 und die Ölwanne 4 sind am Kurbelgehäuse 1 angeflanscht.In the crankcase 1 , a crankshaft 5 is supported in bearings (Lagerdek angle 18 ). The crankshaft 5 and the parts rotating with it are covered by a shell 6 opposite the oil pan 4 . The shell 6 and the oil pan 4 are flanged to the crankcase 1 .

Die Schale 6 besitzt eine etwa in der Mitte bezüglich der Hochachse 7 des Kurbelgehäuses 1 liegende Öffnung 8, die auch als Ölhobel, also mit einem Schlitz, dessen Schräge gleichsinnig mit einer Drehrichtung 9 der Kurbelwelle 5 in einem spitzen Winkel zur Hochachse 7 des Kurbelgehäuse 1 verläuft, ausgebil­ det sein kann.The shell 6 has an opening 8 located approximately in the middle with respect to the vertical axis 7 of the crankcase 1 , which also acts as an oil plane, that is to say with a slot, the slope of which is in the same direction as a direction of rotation 9 of the crankshaft 5 at an acute angle to the vertical axis 7 of the crankcase 1 runs, can be trained.

Ferner kann die Schale 6 auch teilweise entlang der Kontur ei­ ner Pleuelgeige 10, also der Kurve, die die Bahnen der jeweils äußersten Punkte von Pleuel und Kurbelwelle 5 in bezug auf die Kurbelwellenachse während einer Umdrehung des Kurbeltriebes einhüllt, verlaufen.Furthermore, the shell 6 can also run partially along the contour of a connecting rod violin 10 , that is to say the curve which envelops the tracks of the outermost points of the connecting rod and crankshaft 5 with respect to the crankshaft axis during one revolution of the crank mechanism.

Erfindungsgemäß ist eine Dämpfungskammer 11 an der Schale 6 angebracht und verläuft zwischen den beiden Stirnseiten des Kurbelgehäuses 1 in etwa achsparallel zur Kurbelwelle 5 und besteht aus zwei stegförmigen Seitenwänden 12, 13 und einer Bodenplatte 14, die in einem Abstand unterhalb der Schale 6 angeordnet ist. Seitlich in der Bodenplatte 14 der Dämpfungs­ kammer 11 sind Ablauföffnungen 15 und 16, insbesondere versetzt zur Öffnung 8, angebracht, die dem Ölabfluß und dem Gasaus­ tausch zwischen Dämpfungskammer 11 und dem unteren Kurbelge­ häuseteil 17 dienen.According to the invention, a damping chamber 11 is attached to the shell 6 and runs between the two end faces of the crankcase 1 approximately axially parallel to the crankshaft 5 and consists of two web-shaped side walls 12, 13 and a base plate 14 which is arranged at a distance below the shell 6 . Laterally in the bottom plate 14 of the damping chamber 11 drain openings 15 and 16 , in particular offset to the opening 8 , are attached, the oil drain and the gas exchange between the damping chamber 11 and the lower crank part 17 serve.

Durch die erfindungsgemäße Anordnung der Dämpfungskammer 11 werden die vertikalen Gasimpulse über die Öffnung 8 in die Dämpfungskammer 11 geführt, in der die Gase umgelenkt werden und damit eine direkte Beaufschlagung der Ölwanne 4 durch die Wucht der vertikalen Gassäule vermieden wird. Dadurch kann die Schallabstrahlung der Ölwanne 4 wesentlich verringert werden. In der Dämpfungskammer 11 kommt es zu einer Verteilung der vertikalen Gasimpulse in alle Richtungen in einer Schicht in etwa achsparallel zur Kurbelwelle 5.Due to the arrangement of the damping chamber 11 according to the invention, the vertical gas impulses are guided through the opening 8 into the damping chamber 11 , in which the gases are deflected and thus a direct exposure to the oil pan 4 by the force of the vertical gas column is avoided. As a result, the sound radiation from the oil pan 4 can be significantly reduced. In the damping chamber 11 there is a distribution of the vertical gas pulses in all directions in a layer approximately axially parallel to the crankshaft 5 .

Der Strömungsausgleich der Gase in der Dämpfungskammer 11 kann entweder über die Ablauföffnungen 15 und 16, durch die Öffnung 8 oder über die offenen Stirnseiten der Dämpfungskammer 11 er­ folgen.The flow compensation of the gases in the damping chamber 11 can follow it either through the drain openings 15 and 16 , through the opening 8 or over the open end faces of the damping chamber 11 .

In Fig. 2 ist ein Teil eines Kurbelgehäuses 19 mit Ölwanne 20 in einer Ausführung für einen Motor mit Ausgleichswelle 21 un­ terhalb einer Kurbelwelle 22 dargestellt.In Fig. 2, a part of a crankcase 19 with oil pan 20 is shown in an embodiment for an engine with balance shaft 21 un below a crankshaft 22 .

In einer Schale 23, die die Kurbelwelle 22 und die mit ihr um­ laufenden Teile zur Ölwanne 20 hin abdeckt, schließt sich ein schalenförmiger Ansatz 24 an, der die Ausgleichswelle 21 mit deren Ausgleichsgewichten 25 und den Ausgleichsgewichten 25 gegenüberliegenden Stegen 26 in gleichbleibend geringem Abstand 27 teilweise überdeckt.A shell 23 , which covers the crankshaft 22 and the parts running around it towards the oil pan 20 , is followed by a bowl-shaped extension 24 , which provides the balancing shaft 21 with its balancing weights 25 and webs 26 located opposite the balancing weights 25 at a constant short distance 27 partially covered.

Die Ausgleichswelle 21 mit den Stegen 26 bildet mit dem schalenförmigen Ansatz 24 eine Dämpfungskammer 31, die zwischen den beiden Stirnseiten des Kurbelgehäuses 19 in etwa achsparallel zur Kurbelwelle 22 verläuft.The balance shaft 21 with the webs 26 forms with the bowl-shaped extension 24 a damping chamber 31 , which runs approximately axially parallel to the crankshaft 22 between the two end faces of the crankcase 19 .

In dem schalenförmigen Ansatz 24 der Schale 23 ist eine Öffnung 28 etwa in der Mitte bezüglich der Hochachse 29 des Kurbelge­ häuses 19 angebracht, die auch als Ölhobel ausgebildet sein kann. Die Öffnung 28 verbindet den Kurbelraum 30 mit der Dämp­ fungskammer 31 und dient dem Ölabfluß sowie dem Gasaustausch zwischen Dämpfungskammer 31 und unterem Kurbelgehäuseteil 32.In the shell-shaped extension 24 of the shell 23 , an opening 28 is attached approximately in the middle with respect to the vertical axis 29 of the crankcase 19 , which can also be designed as an oil plane. The opening 28 connects the crank chamber 30 with the damping chamber 31 and serves the oil drain and gas exchange between the damping chamber 31 and the lower crankcase part 32nd

Die Dämpfungskammer 31 wird mindestens durch die Flanken des Gegengewichtes 25 gebildet, kann aber auch durch mehrere Stege 26 in im wesentlichen radiale Segmente 33 unterteilt sein. Die Stege 26 bilden mit den Ausgleichsgewichten 25 einen gemein­ samen Durchmesser. The damping chamber 31 is formed at least by the flanks of the counterweight 25 , but can also be divided into essentially radial segments 33 by a plurality of webs 26 . The webs 26 form with the counterweights 25 a common diameter.

Die Ausgleichswelle 21 dreht sich in dem schalenförmigen Ansatz 24 hinter der Öffnung 28 in geringem Abstand 27, so daß der Hauptteil der von den Kolben kommenden Gasstöße auch hier in alle Richtungen in einer Schicht in etwa achsparallel zur Kur­ belwelle 22 verteilt werden und eine unmittelbare Beaufschla­ gung der Ölwanne 20 mit den pulsierenden Gassäulen unter dem Kolben vermieden wird, wodurch eine erhebliche Verringerung der Schallabstrahlung der Ölwanne 20 erreicht werden kann.The balance shaft 21 rotates in the bowl-shaped extension 24 behind the opening 28 at a short distance 27 , so that the main part of the gas surges coming from the pistons are distributed here in all directions in a layer approximately axially parallel to the cure 22 and a direct Beaufschla supply of the oil pan 20 with the pulsating gas columns under the piston is avoided, whereby a significant reduction in the sound radiation of the oil pan 20 can be achieved.
