Description

  

      Vibrationsfreier    Explosionsmotor mit     gegenläufigen    Kolben.    Zur Erreichung eines     vibrationsfreien     Laufes sind schon Explosionsmotoren mit       gegenläufigen    Kolben vorgeschlagen      -orden.     Diese sogenannten     Boxermotoren    sind in     be-          zug    auf Massenausgleich allen andern Typen       überlegen.    Bei den bekannten derartigen 31o  1     oren    wirkten aber entweder die     Pleuelstan-          (-en    auf eine gemeinsame Kurbelwelle,

   was  eine den Kräfteausgleich störende     Verset-          zung    der Zylinder zueinander bedingte, oder       clie        Pleuelstangen        wurden    in der Zylinder  vcbse herausgeführt, was die gleichzeitige       Verwendung    der Kolben als Ladepumpen  kolben     verunmöglichte.     



  Gemäss der Erfindung     sollen    diese     Män-          dadurch        beseitigt    sein,     da.ss    die Pleuel  stangen ausserhalb der Kolben und des Zy  linder; an den Kolbenbolzen     angreifen    und       auf    zwei gesonderte Kurbelwellen wirken.  



  Auf der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes darge  stellt.     Bei        dein    im Schnitt     gezeichneten        1Io-          tor    greifen die Pleuelstangen 1 der beiden       ;egenlä        ufigen    Kolben 2 an deren Kolbenbol  zen 3 ausserhalb der Kolben und des     gemein-          samen    Zylinders 10 an und wirken auf zwei       gesonderte    Kurbel-wellen B.

   Die Kolbenbol  zen 3 -sind dabei in Schlitzen 4 des Zylinders  <B>10</B>     geradegeführt.    Die beiden innern Kolben  enden 5 begrenzen einen gemeinsamen Explo  sionsraum 6, während die äussern Enden 7       ;j1Ladepumpenkolben    für den im Zweitakt       arbeitenden    Motor wirken. Die Kurbelwellen  8 sind durch     Kegelradgetriebe    und eine Quer-    welle 9 so miteinander verbunden, dass sie  entgegengesetzt drehen. Statt der Kegelrad  getriebe können auch     Scbraubenradgetriebe     verwendet sein. Die     Quer-,velle    9 bildet die  eigentliche Antriebswelle des Motors.



      Vibration-free explosion engine with pistons rotating in opposite directions. To achieve vibration-free operation, explosion engines with pistons rotating in opposite directions have already been proposed. These so-called boxer engines are superior to all other types in terms of mass balancing. In the known 31o 1 ores of this type, however, either the connecting rods acted on a common crankshaft,

   which caused the cylinders to be offset from one another, which would disturb the balance of forces, or the connecting rods were led out of the cylinder, which made it impossible to use the pistons as charge pumps at the same time.



  According to the invention, these shortcomings should be eliminated in that the connecting rods are outside the piston and the cylinder; attack the piston pin and act on two separate crankshafts.



  In the drawing, an execution example of the subject invention is Darge provides. In your 1Iotor drawn in section, the connecting rods 1 of the two contiguous pistons 2 engage their piston pins 3 outside the pistons and the common cylinder 10 and act on two separate crankshafts B.

   The piston pins 3 -are guided straight in slots 4 of the cylinder <B> 10 </B>. The two inner piston ends 5 delimit a common explosion space 6, while the outer ends 7; j1 charge pump pistons act for the two-stroke engine. The crankshafts 8 are connected to one another by bevel gears and a transverse shaft 9 so that they rotate in opposite directions. Instead of bevel gears, screw gears can also be used. The transverse shaft 9 forms the actual drive shaft of the motor.
