Description

  

      Brennkraftmaschine.       Die Erfindung bezieht sich auf     eine        Brenn-          kraftmaschine,    bei welcher das Kurbelgehäuse  als Gleitlager für die zylindrisch geformten  Kurbelwangen dient. Die Erfindung besteht  darin, dass sowohl das Kurbelgehäuse als auch  die zu einer Pleuelstange gehörenden beiden       T@urbelwangenkörper    aus Leichtmetall gefer  tigt und die Gleitflächen eines der beiden  aufeinander gleitenden Teile verchromt sind.  



  Die zu einer Pleuelstange gehörenden bei  den     Leichtmetall-Kurbelwangen    können durch  eine Stahlbüchse miteinander verbunden sein,  auf der auf Rollen oder auf Gleitlager das       Kurbelwellenauge    der     Pleuelstange    läuft.  Zweckmässig sind in den Kurbelwangen Stahl  körper als zum Auswuchten dienende Aus  gleichsgewichte angeordnet.- Auf diese Weise  ist trotz der erheblichen Gewichtsverminde  rung des Motors ein leichtes Auswuchten  möglich. Durch die oben angegebene Lagerung  der Kurbelwelle wird eine sehr niedrige spe  zifische Flächenbelastung     des,    Kurbelwellen  lagers erzielt.  



  In der Zeichnung ist ein     Ausführungsbei-          spiel    des Erfindungsgegenstandes veranschau  licht. Der luftgekühlte Leichtmetallzylinder 1  weist eine verchromte Lauffläche 2 auf. Mit 3  ist der Kolben und mit 4 die Pleuelstange be  zeichnet. Das     Kurbelwellenauge    der letzteren  läuft auf Rollen 5, die sich auf einer     Stahl-          biichse    6 abwälzen. Diese Büchse verbindet  die aus Leichtmetall hergestellten zylindri  schen     Kurbelwangenkörper    7 und 8 miteinan  der, die unmittelbar auf der verchromten In-         nenseite    9 des aus Leichtmetall bestehenden  Kurbelgehäuses 10 gleiten.

   Die in den Kurbel  wangen angeordneten     zylindrischen    Stahlkör  per 11 und 12 bilden die zum Auswuchten die  nenden Ausgleichsgewichte. Mit 13 ist die       Zündmaschine-    des Motors angedeutet. Auf  der abtreibenden Welle 14 ist das Antriebs  zahnrad 15 befestigt.



      Internal combustion engine. The invention relates to an internal combustion engine in which the crankcase serves as a slide bearing for the cylindrically shaped crank webs. The invention consists in that both the crankcase and the two door cheek bodies belonging to a connecting rod are made of light metal and the sliding surfaces of one of the two parts sliding on one another are chrome-plated.



  The light metal crank webs belonging to a connecting rod can be connected to one another by a steel sleeve on which the crankshaft eye of the connecting rod runs on rollers or on plain bearings. Steel bodies are expediently arranged in the crank webs as balancing weights. In this way, despite the considerable reduction in weight of the engine, easy balancing is possible. Due to the above-mentioned storage of the crankshaft, a very low specific surface loading of the crankshaft bearing is achieved.



  An exemplary embodiment of the subject matter of the invention is illustrated in the drawing. The air-cooled light metal cylinder 1 has a chrome-plated running surface 2. With 3 the piston and 4 with the connecting rod be distinguished. The crankshaft eye of the latter runs on rollers 5 which roll on a steel sleeve 6. This bushing connects the cylindrical crank web bodies 7 and 8 made of light metal, which slide directly on the chrome-plated inside 9 of the crankcase 10 made of light metal.

   The cylindrical steel bodies arranged in the crank cheeks by 11 and 12 form the balancing weights that nenden. With 13 the ignition machine of the engine is indicated. On the output shaft 14, the drive gear 15 is attached.
