In MTZ Motortechnische Zeitschrift 52 (1991) Heft 10, Seiten
486 bis 493, ist eine Brennkraftmaschine beschrieben,
die unter anderem einen Zylinderkopf, ein Kurbelgehäuse und
eine Ölwanne umfaßt. An einer quer zu zwei Längsseiten verlaufenden
Stirnseite des Kurbelgehäuses ist ein Kettentrieb
zum Antrieb der Nockenwelle angeordnet. Außerdem befinden
sich an der Stirnseite noch Antriebsmittel für eine Wasserpumpe,
eine Lichtmaschine und einen Kühlerlüfter, wobei
diese Antriebsmittel als Riementrieb ausgeführt sind. Um
das Eindringen von Schmutz und Feuchtigkeit in den Kettentrieb
für die Nockenwelle sowie auch in den Nockenwellen-
und Ventilsteuerungsbereich zu vermeiden, ist der Kettentrieb
teilweise in dem Ventildeckel und dem Zylindergehäuse
aufgenommen und im übrigen Bereich durch eine entsprechend
gestaltete Haube abgedeckt. Eine derartige Haube
reicht bis an den Rand der Ölwanne, die über das stirnseitige
Ende des Kurbelgehäuses hervorsteht. Durch eine derartige
Konstruktion ergeben sich viele Dichtkanten, so daß
eine Vielzahl von Dichtelementen vorzusehen sind. Außerdem
ist die Abdichtung von Flanschen, an denen drei Teile zusammengefügt
sind, allgemein sehr schwierig aufgrund der
unterschiedlichen Ausdehnungskoeffizienten und Richtungen
infolge Temperatureinwirkung.In MTZ Motortechnische Zeitschrift 52 (1991)

Die wesentlichen Vorteile der Erfindung sind insbesondere darin zu sehen, daß durch die Verlängerung der Seitenwände der Ketten- beziehungsweise Riementrieb seitlich eingefaßt wird, wobei die Seitenwandabschnitte bei der Herstellung des Kurbelgehäuses angegossen werden und dafür kein zusätzlicher Herstellungsprozeß erforderlich ist. Es ergeben sich dadurch Möglichkeiten einer einfacheren Gestaltung der Dichtflächen, wobei insbesondere wichtig ist, daß eine gute Formbeständigkeit erreicht wird und Dichtkanten mehrerer aneinanderstoßender Teile vermieden werden.The main advantages of the invention are in particular to be seen in that by extending the side walls the chain or belt drive bordered on the side is, the side wall sections in the manufacture of the crankcase are cast on and no additional Manufacturing process is required. Surrender thereby opportunities for a simpler design of the Sealing surfaces, it is particularly important that a good Dimensional stability is achieved and sealing edges of several abutting parts can be avoided.
Eine bevorzugte Weiterbildung des Erfindungsgegenstandes besteht darin, daß die Seitenwandabschnitte einen Steuerkasten mit einer zylinderkopfseitigen Aussparung und einer ölwannenseitigen Aussparung bilden. Durch diese Gestaltung steht der innerhalb des Steuerkastens gebildete Hohlraum sowohl mit der Kammer, in der sich das Nockenwellenrad befindet, als auch mit der Ölwanne in Verbindung, wodurch die Schmierung des Kettentriebs und Rückführung des Öls in die Ölwanne problemlos möglich ist. Zur Versteifung der Seitenwandabschnitte und zur weiteren Vereinfachung der Dichtflächen sind vorzugsweise Verbindungsstege vorgesehen, wobei ein Verbindungssteg zwischen den oberen Enden der Seitenwandabschnitte angeordnet ist, der die zylinderkopfseitige Aussparung begrenzt, und ein weiterer Verbindungssteg zwischen den unteren Enden der Seitenwandabschnitte vorgesehen ist, der die ölwannenseitige Aussparung begrenzt. Dabei ist es weiterhin zweckmäßig, daß die oberen Enden der Seitenwandabschnitte und gegebenenfalls der Verbindungssteg zu einer Zylinderkopfflanschfläche des Kurbelgehäuses fluchtend verlaufen, so daß sich ein einheitlicher Dichtrahmen für die entsprechende Dichtfläche des Zylinderkopfes ergibt. Analog zu dieser Ausgestaltung sollten auch die unteren Enden der Seitenwandabschnitte und gegebenenfalls der untere Verbindungssteg mit einem Ölwannenflansch des Kurbelgehäuses fluchtend verlaufen, so daß auch die Dichtfläche der Ölwanne in einer Ebene liegt. Eine weitere vorteilhafte Ausgestaltung besteht darin, daß die vorderen Enden der Seitenwandabschnitte und gegebenenfalls die Verbindungsstege eine ebene Fläche bilden, so daß die stirnseitige Öffnung des Steuerkastens durch einen einfach gestalteten Deckel, beispielsweise in Form einer Platte geschlossen werden kann.A preferred further development of the subject matter of the invention is that the side wall sections have a control box with a recess on the cylinder head and a Make a recess on the oil pan side. Through this design stands the cavity formed within the control box with the chamber in which the camshaft gear is located, as well as in connection with the oil pan, whereby the Lubrication of the chain drive and return of the oil to the Oil pan is easily possible. For stiffening the side wall sections and to further simplify the sealing surfaces connecting webs are preferably provided, wherein a connecting web between the upper ends of the side wall sections is arranged, the cylinder head side Cutout limited, and another connecting bridge between the lower ends of the side wall portions that limits the recess on the oil pan side. It is it is also appropriate that the upper ends of the side wall sections and if necessary the connecting bridge aligned with a cylinder head flange surface of the crankcase run so that there is a uniform sealing frame for the corresponding sealing surface of the cylinder head. Analogous to this configuration, the lower ones should also Ends of the side wall sections and, if necessary, the lower connecting web with an oil pan flange of the crankcase run flush, so that the sealing surface the oil pan is on one level. Another beneficial one Design is that the front ends the side wall sections and, if necessary, the connecting webs form a flat surface so that the front Opening the control box by a simply designed Cover, for example closed in the form of a plate can be.
