Description

  

  Motor mit beiderseits der     Kurbelwelle    einander gegenüberliegenden     Zylindern.       Zwecks vollkommener Ausnutzung des für  den im Fahrzeug gelagerten Motor vorge  sehenen     Motorraumes    wurden bereits Motoren  vorgeschlagen, bei welchen die Zylinder  einander gegenüber     in    einer oder in mehre  ren     übereinanderliegenden    Ebenen     bezw.    in  zueinander schrägen, sich in der Achse der  Kurbelwelle schneidenden Ebenen     angeordnet     sind.

   Die letztangeführte Anordnung besitzt  den Vorteil, dass bei. gleicher Zylinderzahl im  Gegensatz zu einem Motor mit in zwei Ebe  nen     übereinanderliegenden    Zylindern nur     eine     einzige Kurbelwelle angeordnet ist, so dass sich  die Konstruktion wesentlich verbilligt. Die Er  findung betrifft einen solchen Motor und be  zweckt eine solche Ausbildung der Kurbel  welle, dass die Verteilung der Arbeitstakte  über den Umlauf ganz regelmässig ist, ob  wohl die Zylinder in verschiedenen Ebenen  liegen.

   Erfindungsgemäss     sind    die     Kurbel-          %t-ellenzapfen    in zwei im gleichen Winkel  schräg zueinander liegenden Ebenen ange  ordnet und die Pleuelstangen derart an diese  Zapfen angeschlossen, dass in den Totpunkt-    lagen der Kolben die Pleuelstangen in den  Ebenen der Zylinder liegen.    Die beiliegende Zeichnung veranschau  licht schematisch ein Ausführungsbeispiel des  Erfindungsgegenstandes.    Im Kurbelgehäuse 1 des Motors, auf dem  die Zylinder 2 in zwei zueinander schräg lie  genden Ebenen     1-I    und     II-II    liegen, ist  die Kurbelwelle 3 in der Schnittlinie dieser  Ebenen gelagert.

   Die Zapfen 4 der Kur  belwelle 3 liegen jedoch nicht in einer Ebene,  sondern abwechselnd in den Ebenen     1-I    und       II-II,    je nachdem, zu welchem Zylinder  der betreffende Zapfen gehört. Wie aus der       Zeichnung    zu ersehen ist, sind also die Pleuel  stangen 5 an     die    Zapfen 4 derart angeschlos  sen, dass in den     Totpunktlagen    der Kolben die  Pleuelstangen in der Ebene     I-I        bezw.          II-II    der Zylinder liegen.



  Engine with cylinders facing each other on both sides of the crankshaft. In order to make full use of the engine compartment provided for the engine mounted in the vehicle, engines have already been proposed in which the cylinders BEZW each other in one or more superimposed levels. are arranged in mutually inclined planes intersecting in the axis of the crankshaft.

   The last-mentioned arrangement has the advantage that at. the same number of cylinders, in contrast to an engine with cylinders lying one above the other in two levels, only a single crankshaft is arranged, so that the construction is significantly cheaper. The invention relates to such a motor and be designed such a design of the crankshaft that the distribution of the work cycles over the circuit is quite regular, although the cylinders are in different planes.

   According to the invention, the crank pins are arranged in two planes inclined at the same angle to one another and the connecting rods are connected to these pins in such a way that the connecting rods are in the planes of the cylinders in the dead center positions of the pistons. The accompanying drawing illustrates schematically an embodiment of the subject invention. In the crankcase 1 of the engine on which the cylinder 2 lie in two mutually inclined planes 1-I and II-II, the crankshaft 3 is mounted in the intersection of these planes.

   The pin 4 of the cure belwelle 3 are not in one plane, but alternately in the levels 1-I and II-II, depending on which cylinder the pin in question belongs to. As can be seen from the drawing, so the connecting rods 5 are connected to the pin 4 so ruled out that in the dead center positions of the piston, the connecting rods in the plane I-I respectively. II-II of the cylinder lie.
