Abstract

The split crankcase is used for facilitating the accommodation of the channels for distribution of the lubricating oil. These channels are readily flushed for cleaning purposes and the crankshaft is readily fitted. The crankcase is split by a vertical plane which passes through the axis of the crankshaft bearings. This arrangement is used especially for a V-shaped engine arrangement. In the diagram the crankcase is split along the vertical plane R. The crankcase is bolted together by main connection bolts which pass through the crankcase above and below the crank bearing position. Additional peripheral bolts are used for clamping the crankcase together at the top and bottom. Longitudinal channels are machined into the crankcase at the top and bottom and these form closed channels when the crankcase is bolted together. The lubricant channel in the upper part has cast bosses for accommodating nozzles for spraying the pistons with oil.

Kurbelgehäuse für eine BrennkraftmaschineCrankcase for an internal combustion engine

Die bisher bekannten Kurbeigehäuse sind aus einem Teil als Gehäuse eines Tunneltyps ausgebildet.The previously known crank housings are made of one part as a housing of a tunnel type.

Bei bekannten Tunnelgehäusen ist die Ausbildung und Anordnung der Kanäle zur Schmierölverteilung äußerst schwierig , und eine voll- · ständige Säuberung dieser Kanäle von mehr oder weniger verfestigten Ablagerungen, die unter Umständen von Frischöl wieder aufgeschwemmt und zu den Schmierteilen gefördert werden können, ist. nicht möglich. Ferner ist auch die Montage der Kurbelwelle kompliziert und aufwendig.In known tunnel housings, the design and arrangement of the channels for distributing the lubricating oil is extremely difficult, and it is complete Cleansing of these channels of more or less solidified deposits, which under certain circumstances could be floated up again by fresh oil and can be conveyed to the lubrication parts is. not possible. Furthermore, the assembly of the crankshaft is complicated and expensive.

Aufgabe der Erfindung ist es, die Schmierung durch· geeignete Anordnung der Schmierkanäle im Kurbelgehäuse zu verbessern und die Montage der Kurbelwelle zu vereinfachen.The object of the invention is to provide lubrication by means of suitable To improve the arrangement of the lubrication channels in the crankcase and to simplify the assembly of the crankshaft.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine senkrechte Längsteilung in einer durch die Achse der Kurbelwellenlager verlaufenden Trennebene.This object is achieved according to the invention by a vertical Longitudinal division in a running through the axis of the crankshaft bearings Parting plane.

Bei einer vorteilhaften Weiterbildung des erfindungsgemäßen Gehäuses sind die beiden Hälften des Kurbelgehäuses durch Hauptverbindungsschrauben, die Angüsse der Kurbelwellenlager durchragen, und durch Zusatzschrauben am Umfang miteinander verbunden. Dabei kann in der Teilungsebene mindestens ein Ölkanal verlaufen, dessen Wände in den oberen Teilen der beiden Gehäusehälften Angüsse zur Aufnahme von Düsen zum Anspritzen der Kolben aufweisen.In an advantageous development of the housing according to the invention are the two halves of the crankcase by main connecting screws that protrude through the sprues of the crankshaft bearings, and connected to each other by additional screws on the circumference. At least one oil channel can run in the dividing plane, its Walls in the upper parts of the two housing halves have sprues for receiving nozzles for spraying on the pistons.

Eine Ausführung des erfindungsgemäßen Kurbelgehäuses wird im folgenden anhand der schematischen Zeichnung ausführlich beschrieben:An embodiment of the crankcase according to the invention is described in detail below with reference to the schematic drawing:

Das Kurbelgehäuse 1 ist in einer senkrechten Teilungsebene R längsgeteilt, die durch die Achse der - nicht im einzelnen dargestellten - Kurbelwellenlager 3' hindurchgeht. Die beiden Hälften 2 und des Kurbelgehäuses 1 sind durch Hauptverbindungsschrauben 4, 4' miteinander verbunden, die Lagerangüsse 11 der Kurbelwellenlager 3' durchragen. Ferner sind beide Hälften 2 und 3 des Kurbelgehäuses an ihrem Umfang durch Zusatzschrauben 5, 5' verbunden. In der Teilungsebene R ist mindestens ein Kanal 7 oder 8 zur Verteilung des Öls im Motor und an den Zylinder- bzw. Kolbenwänden vorge-The crankcase 1 is divided longitudinally in a vertical dividing plane R, which is through the axis of FIG - Crankshaft bearing 3 'passes through. The two halves 2 and of the crankcase 1 are connected to one another by main connecting screws 4, 4 ', the bearing sprues 11 of the crankshaft bearings 3' stick through. Furthermore, both halves 2 and 3 of the crankcase are connected on their periphery by additional screws 5, 5 '. In the At least one channel 7 or 8 is provided for the distribution of the oil in the engine and on the cylinder or piston walls.

sehen. Die Wände der Kanäle 8 sind in den oberen Teilen der beiden Hälften 2, 3 des Kurbelgehäuses 1 mit Angüssen 9, 91 versehen, in denen Düsen 10, 10' zum Bespritzen der Kolben gelagert sind.see. The walls of the channels 8 are provided in the upper parts of the two halves 2, 3 of the crankcase 1 with sprues 9, 9 1 , in which nozzles 10, 10 'are mounted for spraying the pistons.

Die Vorteile des erfindungsgemäßen Kurbelgehäuses bestehen in der vereinfachten Ausbildung der Kanäle, in der Beseitigung der Unreinigkeiten aus den Kanälen bei der Bearbeitung und in einer einfachen und leichten Lagerung der Kurbelwelle.The advantages of the crankcase according to the invention consist in the simplified design of the channels, in the elimination of the Impurities from the channels in processing and in a simple and easy storage of the crankshaft.
