Description

Pleuelstangenlagerung für Zweitakt-Brennkraftmaschinen mit stern- oder fächerförmig angeordneten Zylindern Die Erfindung bezieht sich auf eine Pleuelstangenlagerung für Zweitakt-Brennkraftmaschinen mit stern- oder fächerförmiger Zylinderanordnung, bestehend aus einer Hauptpleuelstange und an deren Pleuelkopf mittels Kugelgelenke angelenkten Nebenpleuelstangen, und betrifft die Anlenkung der Kugelköpfe der Nebenpleuelstangen am Hauptpleuelkopf.Connecting rod bearings for two-stroke internal combustion engines with star or cylinders arranged in a fan shape. The invention relates to a connecting rod bearing for two-stroke internal combustion engines with star or fan-shaped cylinder arrangement, consisting of a main connecting rod and its connecting rod head by means of ball joints articulated secondary connecting rods, and concerns the articulation of the ball heads of the secondary connecting rods on the main connecting rod end.

Bei den bekannten Bauarten werden die Kugelköpfe der Nebenpleuelstangen einzeln mittels einzelner Deckel in ihren Pfannen gehalten. Dabei ergeben sich jedoch infolge der für jeden Deckel- erforderlichen Verschraubung große Abmessungen der einzelnen Dekkel und damit des gesamten Pleuelkopfes.In the known designs, the ball heads of the auxiliary connecting rods individually held in their pans by means of individual lids. However, this results due to the screwing required for each cover large dimensions of the individual cover and thus the entire connecting rod head.

Gemäß der Erfindung werden sämtliche Kugelköpfe der Nebenpleuelstangen durch zwei seitlich an den Pleuelkopfangeschraubte ringförmige Blechpreßlinge in ihren Pfannen gehalten, welche die Kugelköpfe mit kugelförmigen Aufstülpungen umfassen und gegebenenfalls parallel zur Kurhelzapfenachse verlaufende zylindrische Ausbuchtungen aufweisen, welche die Kugelköpfe mit Spiel durchdringende, gegen Verdrehen sichernde Sicherungsstifte in Stellung halten. Diese ringförmigen Blechpreßlinge ermöglichen eine raum- und gewichtsparende Form des Hauptpleuelkopfes.According to the invention, all of the ball heads of the secondary connecting rods are by means of two ring-shaped pressed sheet metal parts screwed to the side of the connecting rod head in held their sockets, which include the spherical heads with spherical protuberances and, if necessary, cylindrical bulges running parallel to the crank pin axis have which the ball heads with play penetrating, locking against rotation Hold the locking pins in place. These annular pressed sheet metal allow a space- and weight-saving form of the main connecting rod head.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Abb. i zeigt einen Seitenriß des Triebwerkes, zum Teil im Schnitt.The drawing shows an embodiment of the subject matter of the invention shown. Fig. I shows a side elevation of the engine, partly in section.

Abb.2 zeigt einen Schnitt nach Linie A-A in Abb. i in vergrößerter Darstellung. Abb.3 zeigt eine Abwicklung des Pleuelkopfes.Fig.2 shows a section along line A-A in Fig. I on an enlarged scale Depiction. Fig.3 shows a development of the connecting rod head.

Das Triebwerk besteht im wesentlichen aus der Hauptpleuelstange i, mit dem ein Stück mit ihr bildenden Pleuelkopf 2 und den an diesem Pleuelkopf mittels Kugelgelenke 3, ¢, 5, 5' angelenkten Nebenpleuelstangen 6. Die Kugelköpfe 3 der Nebenpleuelstangen werden durch zwei ringförmige Blechpreßlinge 5, 5', die mittels der Schrauben 8 seitlich an den Pleuelkopf 2 angeschraubt sind und sämtliche Kugelköpfe 3 mit kugelschalenförmigen Aufstülpungen 7, 7' von beiden Seiten her umfassen, beweglich in ihren Pfannen gehalten. Um ein unzulässiges Verdrehen des die Spül-und Auspuffschlitze 9 im Arbeitszylinder Io der Maschine steuernden Arbeitskolbens i i zu verhindern, ist ein Sicherungsstift 12 vorgesehen, der den Kugelkopf mittig und parallel zur Kurbelzapfenachse mit Spiel durchdringt. Der Sicherungsstift 12 wird durch Ausbuchtungen 13, 13' in den Abdeckblechen 5, 5' in Stellung gehalten.The engine consists essentially of the main connecting rod i, with the connecting rod head 2 forming a piece with it and the connecting rod head by means of this Ball joints 3, ¢, 5, 5 'articulated secondary connecting rods 6. The ball heads 3 of the Secondary connecting rods are by two annular pressed sheet metal 5, 5 ', which means the screws 8 are screwed laterally to the connecting rod head 2 and all ball heads 3 with spherical shell-shaped protuberances 7, 7 'encompass from both sides, movable kept in their pans. To avoid inadmissible twisting of the flushing and exhaust ports 9 to prevent working piston i i controlling the working cylinder Io of the machine, a locking pin 12 is provided, which the ball head centrally and parallel to Crank pin axis penetrates with play. The locking pin 12 is formed by bulges 13, 13 'held in position in the cover plates 5, 5'.

Die Anlenkung der Pleuelstangen an den Arbeitskolben i i kann in an sich bekannter Weise ebenfalls durch Kugelgelenke i9. 2o und 21 erfolgen. Letztere sind in gleicher Weise wie die Pleuelkopfgelenke 3, q., 5, 5' durch einen Sicherungsstift 22 gegen unzulässiges Verdrehen gesichert.The articulation of the connecting rods to the working piston i i can in on known way also by ball joints i9. 2o and 21 take place. Latter are in the same way as the connecting rod joints 3, q., 5, 5 'by a locking pin 22 secured against inadmissible rotation.
