Description

Um die Abmessungen einer Hubkolbenbrennkraftmaschine so gering wie möglich zu halten, muß die Kurbelgehäusewand möglichst eng an die rotierenden Triebwerksteile herangezogen werden. Im Bereich der rotierenden Triebwerksteile wird dadurch die Rückströmung des zur Schmierung und Kühlung der Kolben benötigten Schmieröles in die ölwanne behindert, wodurch erhöhte Öltemperaturen und erhöhte Reibungsmitteldrücke infolge von Verwirbelung des Schmieröles im Triebwerk auftreten. Ferner bewirkt das von den rotierenden Triebwerksteilen abgeschleuderte öl eine übermäßige Verschäumung des an den Gehäusewänden zurückfließenden Schmieröls.In order to keep the dimensions of a reciprocating internal combustion engine as small as possible, the crankcase wall must be drawn as close as possible to the rotating engine parts. In the area of the rotating engine parts, the return flow of the lubricating oil required for lubrication and cooling of the pistons into the oil pan is hindered, resulting in increased oil temperatures and increased friction mean pressures as a result of turbulence in the lubricating oil in the engine. Furthermore, the oil thrown off by the rotating engine parts causes excessive foaming of the lubricating oil flowing back on the housing walls.

Der Erfindung liegt die Aufgabe zugrunde, das Schmieröl so in die ölwanne zurückzuführen, daß die oben beschriebenen ungünstigen Verhältnisse vermieden werden, ohne daß aber gleichzeitig das Kurbelgehäuse nennenswert vergrößert wird. Sie wird erfindungsgemäß dadurch gelöst, daß in geringem Abstand zur äußeren The invention is based on the object of returning the lubricating oil to the oil pan in such a way that the unfavorable conditions described above are avoided, but without the crankcase being significantly enlarged at the same time. It is achieved according to the invention in that at a small distance from the outer

Geliäusewand im Bereiche der Pleuellager eine innere G-ehäusewand vorgesehen ist. Zwischen der inneren und äußeren Gehäusewand kann das Schmieröl ungehindert zurückfließen, ohne daß es durch abgeschleudertes Schmieröl, das von der inneren Gehäusewand aufgefangen wird, verschäumt wird.Geliäusewand an inner G-ehäusewand in the area of the connecting rod bearings is provided. The lubricating oil can flow back unhindered between the inner and outer housing walls without passing through thrown off lubricating oil, which is caught by the inner housing wall, is foamed.

In der Praxis hat es sich gezeigt, daß ein Abstand von ca. 5 bis 15 mm günstige Verhältnisse in Bezug auf das Bauvolumen ergibt. Das Bauvolumen kann gemäß einer weiteren Ausgestaltung der Erfindung dadurch klein gehalten werden, daß die innere Gehäusewand durch ein Leitblech gebildet wird, so kann die innere Gehäusewand extrem dünn sein. Unter Umständen läßt sich eine solche innere Gehäusewand auch nachträglich noch einbauen, wenn das Leitblech unter Verwendung von Distanzstücken an die äußere Gehäusewand angeschraubt wird.In practice it has been shown that a distance of approx. 5 to 15 mm results in favorable conditions with regard to the structural volume. According to a further embodiment of the invention, the structural volume can be kept small in that the inner housing wall is formed by a baffle, the inner housing wall can be extremely thin. Such a Install the inner housing wall later if the guide plate is attached to the outer housing wall using spacers is screwed on.

In geringem Abstand zu den äußeren G-ehäusewänden 2 des Kurbelgehäuses 1 sind im Bereich der nicht dargestellten Kurbelkröpfung innere Gehäusewände 3 vorgesehen. Zwischen den äußeren Gehäusewänden 2 und den inneren Gehäusewänden 3 sind Zwischenräume 4 gebildet, durch die das Schmieröl von den höher liegenden Gehäuseteilen in den Ölsumpf zurückfließen kann. Mit dünnen Linien 5 sind die Konturen der Pleuelgeigen angedeutet.1 with the crankcase of a reciprocating internal combustion engine is designated 9, the cylinders of which are arranged in a Y-shape. Inner housing walls 3 are provided at a small distance from the outer G housing walls 2 of the crankcase 1 in the area of the crank crank (not shown). Between the outer housing walls 2 and the inner housing walls 3, spaces 4 are formed through which the lubricating oil can flow back from the higher-lying housing parts into the oil sump. The contours of the connecting rod violins are indicated by thin lines 5.
