Description

Die bisher übliche Verbindung zwischen Pleuelstange und Kolbenbolzen hat den Nachteil, daß die Pleuelstange nur in ihrer Schwingungsebene Bewegungsfreiheit besitzt: Da es praktisch nicht möglich ist, die Pleuelstange mit solcher Präzision im Kolben zu montieren, daß sie während des Betriebes nicht auch Beanspruchungen erfährt, die eine wenn auch kleine Bewegungsfreiheit nach allen Richtungen erfordern, so ergibt sich ein vorzeitiger Verschleiß der Teile.The previously common connection between the connecting rod and the piston pin has the disadvantage that the connecting rod can only move freely in its plane of oscillation possesses: Since it is practically impossible to produce the connecting rod with such precision to be mounted in the piston so that they are not stressed during operation experiences that require a small amount of freedom of movement in all directions, this results in premature wear of the parts.

Die Erfindung bezweckt, diesen Mangel zu beheben.The invention aims to remedy this deficiency.

Dies wird dadurch erreicht, daß die Pleuelstange an dem Kolbenbolzen über ein Kugelgelenk angreift. Auf dem Bolzen ist ein Kugelkörper mit axialem Spiel und drehbar befestigt, auf welchem eine von dem Pleuelstangenkopf umfaßte Kugelschale sitzt. Die Sicherung der Verbindung zwischen Kugelschale und Pleuelstangenkopf erfolgt beispielsweise auf der einen Seite durch einen Flansch des Pleuelstangenkopfes, auf der anderen Seite durch einen Sprengring o. dgl.This is achieved by having the connecting rod on the piston pin attacks via a ball joint. On the bolt is a spherical body with axial play and rotatably mounted on which a ball socket comprised by the connecting rod end sits. The connection between the spherical shell and the connecting rod head is secured for example on one side through a flange of the connecting rod head, on the other side by a snap ring or the like.

Die Figur zeigt schematisch ein Ausführungsbeispiel im Schnitt.The figure shows schematically an exemplary embodiment in section.

Auf dem Kolbenbolzen a ist ein Kugelkörper b mit axialem Spiel und drehbar angeordnet. Auf letzterem sitzt eine Kugelschale c mit solcher Bewegungsfreiheit, daß die Pleuelstange d das während des Betriebes unvermeidliche seitliche Spiel besitzt. Die Kugelpfanne c wird von dem Kopf oder Auge e der Pleuelstange umfaßt; die Sicherung der Verbindung zwischen c und e gegen axiale Verschiebung erfolgt auf der einen Seite durch einen Überwurfflansch f des Teiles e, auf der anderen Seite bei g durch einen nicht gezeichneten Sprengring o. dgl.A spherical body b with axial play and rotatable is arranged on the piston pin a. On the latter sits a spherical shell c with such freedom of movement that the connecting rod d has the unavoidable lateral play during operation. The ball socket c is encompassed by the head or eye e of the connecting rod; the connection between c and e is secured against axial displacement on the one hand by a coupling flange f of part e, on the other hand at g by a snap ring or the like, not shown.

Der Kugelkörper b wird in die zweiteilige Kugelschale c eingelegt; sodann wird die Schale c mit der eingelegten Kugel in den Pleuelkopf e eingepreßt, nachdem dieser vorher in heißem C51 auf 9o° C erwärmt worden war. Hierauf wird das Ganze durch den Sprengring g gegen eventuelle axiale Verschiebung gesichert.The spherical body b is inserted into the two-part spherical shell c; then the shell c with the inserted ball is pressed into the connecting rod head e, after it had previously been heated to 90 ° C in a hot C51. Then that will The whole thing is secured against possible axial displacement by the snap ring g.
