Description

  

      .Kolben    für     Verbrennungsmotoren.       Gegenstand vorliegender Erfindung ist  ein Kolben für Verbrennungsmotoren.  



  In der beiliegenden Zeichnung ist eine  beispielsweise Ausführungsform des Kolbens  dargestellt, und zwar zeigt:       Fig.    1 eine Seitenansicht des Kolbens,       Fig.    2 ist ein Schnitt nach der Linie     A-B     der     Fig.    1;       Fig.    3 ist ein Schnitt nach der Linie     C-D     der     Fig.    1;       Fig.    4 zeigt den Kolben von unten ge  sehen;       Fig:    5 ist eine zweite Seitenansicht des  Kolbens.    Der vorzugsweise aus Aluminiumlegierung  bestehende Kolben ist mit zur Aufnahme  von Dichtungsringen bestimmten     NTuten    1  versehen.

   Der Kolbenmantel\ ,2 ist aneinander  diametral     'gegenüberliegenden"Stellen    nach  innen gezogen,     so@dass        Vertiefungen,3,    43 und  3', 4\ entstehen. Zwischen     den,Vertiefungen     3, 4'     bezw.    ,3 ',     4@ist   <B>je."</B>     eine-*nach_    aussen  ragende Leiste 5 vorgesehen. Die-Leisten 5    sind mit Bohrungen 6 versehen, in welche  ein Kolbenzapfen gelagert wird. Um zu er  möglichen, dass sich der Kolben bei seiner       Erwärmung    ausdehnen kann, sind Schlitze 7  vorgesehen, die quer zur Kolbenachse geführt  sind und die zwischen den Leisten 5 ver  laufen.

   Ferner sind Längsschlitze 8 vorge  sehen, die von den Schlitzen 7 aus nach dem  untern Rand des Kolbenmantels geführt sind  ohne aber bis zum Rande zu laufen. Der  untere Kolbenrand ist unverletzt und kann  genau dem Zylinder-Durchmesser entsprechend  bearbeitet werden. Die Leisten 5 sind so  stark gewählt, dass sie dem Kolbenzapfen  ein gutes Lager bieten, ohne dass sie aber  das Gewicht des Kolbens wesentlich erhöhen.



      .Pistons for internal combustion engines. The present invention relates to a piston for internal combustion engines.



  An exemplary embodiment of the piston is shown in the accompanying drawings, in which: Fig. 1 is a side view of the piston; Fig. 2 is a section along the line A-B of Fig. 1; Figure 3 is a section on line C-D of Figure 1; Fig. 4 shows the piston see ge from below; Figure 5 is a second side view of the piston. The piston, which is preferably made of an aluminum alloy, is provided with N-grooves 1 intended to receive sealing rings.

   The piston skirt \, 2 is drawn inwards at points diametrically opposite each other, so @ that indentations, 3, 43 and 3 ', 4 \ arise. Between the "indentations 3, 4" and "3', 4 @ ist < B> each. "</B> an * outwardly protruding bar 5 is provided. The strips 5 are provided with bores 6 in which a piston pin is mounted. In order to he possible that the piston can expand when it is heated, slots 7 are provided which are guided transversely to the piston axis and which run between the strips 5 ver.

   Furthermore, longitudinal slots 8 are easily seen, which are guided from the slots 7 to the lower edge of the piston skirt but without running to the edge. The lower edge of the piston is not damaged and can be machined to match the cylinder diameter. The strips 5 are chosen to be so strong that they offer the piston pin a good bearing without, however, significantly increasing the weight of the piston.

 

Claims (1)

PATENTANSPRUCH: Hohler Kolben für Verbrennungsmotoren mit am Kolbenmantel vorgesehenen Leisten mit Bohrungen zur Aufnahme des Kolbenstangen zapfens, dadurch gekennzeichnet, dass der Kolbenmantel an diametral gegenüberliegen den Stellen nach innen gezogen und die Leisten in diesen Mantelvertiefungen liegend nach aussen ragen. UNTERANSPRUCH: Kolben für Verbrennungsmotoren nach Patentanspruch, gekennzeichnet durch im Kolbenmantel vorgesehene Schlitze, welche in der Längsrichtung des Mantels verlaufen und nicht bis zum untersten Kolbenmantel rand reichen. PATENT CLAIM: Hollow piston for internal combustion engines with strips provided on the piston skirt with bores for receiving the piston rod pin, characterized in that the piston skirt is drawn inwards at diametrically opposite points and the bars protrude outwardly in these skirt recesses. SUBCLAIM: Pistons for internal combustion engines according to patent claim, characterized by slots provided in the piston skirt, which run in the longitudinal direction of the skirt and do not extend to the bottom edge of the piston skirt.
