Description

Die Erfindung bezieht sich auf ein Triebwerk für Brennkraftmaschinen mit stein- oder fächerförmiger Zylinderanordnung, bei welchem mehrere Pleuelstangen in einer Ebene mit Segmenten an dem gemeinsamen Kurbelzapfen angreifen. Die einzelnen Pleuelstangensegmente dieses Tiebwerks _müssen mit R&ksicht auf ihre durch den Pleuelstängenausschlag bedingte gegenseitige Gleitbewegung auf dem gemeinsamen Kurbelzapfen ein bestimmtes gegenseitiges Spiel in dessen Umfangsrichtung aufweisen. Dieses Spiel verhindert eine ordnungsgemräße Olzufuhr zu den Gleitflächen zwischen dein Kurbelzapfen und den Segmenten über eine am Kurbelzapfenumfang ausmündende Schmierbohrung, da dieselbe beim Überfahren des Spiels zwischen zwei benachbarten Segmenten freigelegt wird, so daß, das Schmierä1 ungenutzt in den Kurbelraum spritzt.The invention relates to an engine for internal combustion engines with stone or fan-shaped cylinder arrangement in which several connecting rods attack in a plane with segments on the common crank pin. The single ones The connecting rod segments of this engine _must go through the Connecting rod deflection caused mutual sliding movement on the common crank pin have a certain mutual play in the circumferential direction. This game prevents proper oil supply to the sliding surfaces between your crankpin and the segments via a lubrication hole opening out on the crank pin circumference, there the same exposed when driving over the game between two adjacent segments so that the lubricant injects unused into the crankcase.

Gemäßl- der Erfindung mühdet die Schmierbohrung des Kurbelzapfens in der Kröpfungsebene der Kurbel zwischen den Kurbelwangen aus. In dieser Ebene tritt bei dem vorliegenden Triebwerk die größte Annäherung zweier benachbarter Segmente-ein. Die Segmente sind so bemessen, daß sie sich dort einander bis auf das praktisch zulässige Spiel von einigen Zehntelmillimetern nähern, so daß die Mündung der Schmierbohrung nur durch einen sehr schmalen Spalt überfahren wird und im übrigen -ständig von einem der Segmente abgedeckt ist. Dadurch wird -der Verlust von -Schmieröl auf einen Kleinstwert beschränkt.According to the invention, the lubrication hole of the crank pin is exhausting in the offset plane of the crank between the crank webs. At this level With the present engine, the closest two adjacent segments come together. The segments are dimensioned in such a way that they are there apart from one another practically Approach permissible play of a few tenths of a millimeter so that the mouth of the lubrication hole is only passed through a very narrow gap and otherwise -stead of one of the segments is covered. This reduces the loss of lubricating oil to one Smallest value limited.

In der Zeichnung ist der Erfindungsgegenstand schematisch dargestellt.The subject of the invention is shown schematically in the drawing.

Abb. i zeigt den Erfindungsgegenstand in Verbindung mit dem Triebwerk einer Dreizylindersternmaschine; Abb. 2 -zeigt den Erfindungsgegenstand in-Verbindung mit dem Triebwerk einer Vierzylindersternmaschine; Abb. 3 zeigt einen Schnitt durch die Kröpfungsebene E-E in Abb. i oder Abb. 3.Fig. I shows the subject of the invention in connection with the engine a three-cylinder star engine; Fig. 2 shows the subject matter of the invention in conjunction with the engine of a four-cylinder star engine; Fig. 3 shows a section through the offset plane E-E in Fig. i or Fig. 3.

Die Pleuelstangen a1 bis a4 greifen mit Segmenten bi bis b4 in einer Ebene am Kurbelzapfen c an. Die Segmente werden mittels zweier Segmentringe d, welche gemäß! Abb. 3 die Segmente zu beiden Seiten des Pleuelstangenschaftes gleitend umfassen, in Stellung gehalten. Die Schmierbohrung f im Kurbelzapfen mundet in der Kröpfungsebene E-E zwischen den Kurbelwangen g am Kurbel zapfenumfang aus, in der gemäße Abb. i und 2 benachbarte Segmente jeweils das kleinstmögliche gegenseitige Spiel x aufweisen.The connecting rods a1 to a4 engage with segments bi to b4 in one Level on the crank pin c. The segments are by means of two segment rings d, which according to! Fig. 3 encompass the segments slidingly on both sides of the connecting rod shaft, held in place. The lubrication hole f in the crank pin ends in the offset plane E-E between the crank webs g on the crank pin circumference, in the according to Fig. I and 2 adjacent segments each have the smallest possible mutual play x.
