BeschreibungDescription
Die Neuerung bezieht sich auf eine Brennkraftmaschine, insbesondere DieseliTiotor, mit einer ölwanne und einer ölwannen-Uberwanne. The innovation relates to an internal combustion engine, in particular a diesel engine, with an oil pan and an oil pan over-pan.
Wesentliche Teile der Brennkraftmaschine, so z.B. auch die ölwanne, werden durch den Kurbeltrieb und die Gaskräfte in Schwingungen versetze» Dvch oiese Schwingungen werden von den .'^ndungen dies?'- Teils Luftschallwellen erzeugt und als Geräusche abgestrahlt. Im Zuge immer gr -er werdender Vorbehalte unü Auflagen hinsichtlich der Geräuschdämmung an Kraftwagen auf dem Hintergrund des Umweltschutzes erweist es sich als notwendig, den Schallpegel jedes erdenklichen Teilgeräusches zu reduzieren.Important parts of the internal combustion engine, such as the oil pan, are set into vibration by the crankshaft and the gas forces. These vibrations are generated by the airborne sound waves and emitted as noise. In the wake of ever-increasing reservations and requirements regarding sound insulation in motor vehicles in the interests of environmental protection, it is proving necessary to reduce the sound level of every conceivable partial noise.
So liegt dann der Neuerung die Aufgabe zugrunde, die Ge- -äuschabstrahlung im Bereich der ölwanne zu minimieren.The innovation is therefore based on the task of minimising noise emissions in the area of the oil pan.
Dies wird neuerungsgemäß dadurch erreicht, daß die Ölwannen-Uberwanne mit der Ölwanne über elastische Elenente verbunden ist. Die bekannte Maßnahme, der ölwanne eine ölwannen-Uberwanne zuzuordnen, bringt zwar eine gewisse Geräuschpegelreduzierung, jedoch wird erst ein optimaler Effekt erzielt, wenn die Befestigungspunkte zwischen ölwanne und Uberwanne elastisch gehalten sind, so daß Körperschallkopplung vermieden v/ird.This is achieved in accordance with the innovation by connecting the oil pan upper pan to the oil pan via elastic elements. The known measure of assigning an oil pan upper pan to the oil pan does indeed bring about a certain reduction in the noise level, but an optimal effect is only achieved if the fastening points between the oil pan and upper pan are kept elastic so that structure-borne noise coupling is avoided.
Nach weiteren Merkmalen der Neuerung sind an geeigneten Stellen in den Seitenteilen dor ölwannen-Uberwanne Öffnungen vorgesehen, in denen Gumnimctallbuchsen angeordnet sind, die über Befestigungselemente, z.B. Schrauben, mit der ölwanneAccording to further features of the innovation, openings are provided at suitable places in the side parts of the oil pan upper pan, in which rubber metal bushings are arranged, which are connected to the oil pan via fastening elements, e.g. screws.

fest verbunden sind. Weiterhin ist über die axiale Verlängerung ^er Kernbuchse der Gummimetallbuchse ein Luftraum zwischen ölwanne und öl™^nnsn-tlb'-?rw£-~-.i\3 ' ^rgestellt. So ergibt sich neben dem Effekt der Geräuschpegelreduzierung durch den I,t"*"'"raum zwischen ölwanne und Ölwannen-Uberwanne und der elastischen Anbindung auch eine leichte Montage und Demontage der Ölwannen-Uberwanne, indem nur die Zentrierung zu den Gewindebohrungen gesucht werden muß. Bei der Demontage braucht man nur die Schrauben auszuschrauben und aus der Gummimetallbuchse herauszuziehen, dann kann die Ölwannen-Uberwanne nach unten abgenommen werden.are firmly connected. Furthermore , an air space is created between the oil pan and the oil pan via the axial extension of the core bushing of the rubber-metal bushing. In addition to the effect of reducing the noise level through the space between the oil pan and the oil pan upper pan and the elastic connection, this also makes it easy to assemble and disassemble the oil pan upper pan by only having to find the centering for the threaded holes. When disassembling, you only need to unscrew the screws and pull them out of the rubber-metal bushing, then the oil pan upper pan can be removed downwards.
Eine Optimierung bei der Geräuschpegelreduzierung ist dadurch zu erzielen, daß für die Befestigungsstellen der Gummimetallelemente schwingungsarme Bereiche bzw. Schwingungsknoten gewählt werden. Solcherart wird die Quelle der Lärmentstehung im Körperschallbereich von vorneherein minimiert. Optimization of noise level reduction can be achieved by selecting low-vibration areas or vibration nodes for the fastening points of the rubber-metal elements. In this way, the source of noise in the structure-borne sound area is minimized right from the start.
Die Neuerung ist in einem Ausführungsbeispiel dargestellt und beschrieben.The innovation is shown and described in an example.

Aus dem Teilschnitt gemäß Fig. 2 ist zu ersehen, daß die
Ölwannen-Uberwanne 2 Öffnungen 9 mit Ausstülpungen aufweist,
in denen Gummimetallbuchsen 3 eingepreßt sind. Die Verlängerung 4 der eine Kernbuchsc 5 aufweisenden Gummimetallbuchse
stützt sich an der Seitenwand der ölwanne 1 ab und wird über
Schraube G mit (&Kgr;&tgr; Seitenwand verschraubt. So entsteht ein
Luftraum 11 zwischen ölwanne 1 und ölwannen-Überwanne 2.
Über die Ränder 10 der Ölwannen-Überwanne ist eine mit einem
miLtigen Schlitz versehene Dichtung 7 gestülpt, die gegen
den horizontalen Rand 8 der Ölwanne 1 angedrückt ist.From the partial section according to Fig. 2 it can be seen that the
The oil pan upper pan 2 has openings 9 with protuberances in which rubber-metal bushings 3 are pressed in. The extension 4 of the rubber-metal bushing, which has a core bushing 5, rests on the side wall of the oil pan 1 and is screwed to the side wall via screw G. This creates a
Air space 11 between oil pan 1 and oil pan over-tray 2.
A seal 7 with a central slot is placed over the edges 10 of the oil pan cover, which protects against
the horizontal edge 8 of the oil pan 1.
