Description

Die Lager an den beiden Enden der Kurbelwelle mehrzylindriger Zweitaktbrennkraftmaschinen werden im allgemeinen schlechter geschmiert und gekühlt als die mittleren Lager. Der Grund hierfür ist der auf der Außenseite der Außenlager herrschende konstante Außenluftdruck, während in den Zwischenlagern durch beidseitig wechselnden Unter-und Überdruck in den benachbarten Kurbelkästen jeweils ein Druckgefälle entsteht, in dessen Folge Gemisch in wechselnder Richtung durch das Lager geblasen wird.The bearings at the two ends of the crankshaft of multi-cylinder two-stroke internal combustion engines are generally less lubricated and cooled than the middle bearings. The reason for this is the constant prevailing on the outside of the external bearings Outside air pressure, while in the interim storage facilities by alternating sub-and Overpressure in each of the neighboring crankcases creates a pressure gradient in the consequence of which mixture is blown through the bearing in alternating directions.

Die Erfindung bezweckt, dieselbe Wirkung auch bei den Außenlagern zu erzielen, und zwar dadurch, daß jedes Kurbelwellenaußenlager durch eine Schmierleitung mit einem nicht benachbarten Kurbelkasten verbunden ist. Hierdurch wird auch das Außenlager an wechselnde Drücke angeschlossen, so daß auch diese Lager in wechselnder Richtung vom Gemisch durchspült werden.The invention aims to have the same effect in the case of the external bearings to achieve, namely that each crankshaft outer bearing through a lubrication line is connected to a non-adjacent crankcase. This also makes that External camps connected to changing pressures, so that these camps in changing Direction to be flushed by the mixture.

Zweckmäßig ist zur Erhöhung dieser Wirkung eine besonders druckfeste Dichtung des Außenlagers gegen die Außenluft, damit ein möglichst hohes Druckgefälle entsteht.A particularly pressure-resistant one is useful to increase this effect Sealing of the outer bearing against the outside air, thus the highest possible pressure drop arises.

Nach einer weiteren Ausbildung der Erfindung mündet die Verbindungsschmierleitung im Kurbelkasten an der tiefsten Stelle, vorzugsweise zwischen den Kurbelwangen, so daß das am Kurl>elkastenhoden sich sammelnde C)1 auch ati das Pleuellager bei Druckwechsel gesprüht wird.According to a further embodiment of the invention, the connecting lubrication line opens in the crankcase at the lowest point, preferably between the crank webs, so that the C) 1 that collects on the cortex also ati the connecting rod bearing Pressure change is sprayed.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung in schematischer Darstellung an einer Zweizylinderbrennkraftmaschine. Die KurbelNvellenaußenlager sind mit i bezeichnet. Die Lagerkammern sind durch Leitungen 2 tnit den nicht benachbarten Kurbelkästen 3 verbunden.The drawing shows an exemplary embodiment of the invention in schematic form Representation on a two-cylinder internal combustion engine. The crank shaft outer bearing are denoted by i. The storage chambers are connected to the non-adjacent ones by lines 2 Crank cases 3 connected.
