Deutsche Werke Kiel Akt-Ges. in Kiel*). Kolbenbolzensicherung für Brennkraftmaschinen. Patentiert im Deutschen Reiche vom 21. Oktober 1925 ab.Deutsche Werke Kiel Akt-Ges. in Kiel*). Piston pin retainer for internal combustion engines. Patented in the German Empire on October 21, 1925.
Die Erfindung betrifft eine Sicherung des Kolbenbolzens bei Brennkraftmaschinen, die insbesondere für Aluminiumkolben geeignet ist, bei denen Gewinde nicht anwendbar ist. Es ist bereits bekannt, den rohrförmigen Kolbenbolzen mit dem Kolben durch einen die beiden Teile durchdringenden Stift zu verbinden, der innerhalb der Kolbenbolzenbohrung mittels einer auf den Bolzen geschraubten Mutter und eines Splintes gesichert ist. Eine derartige Verbindung eignet sich aber nur für größere Ausführungen, ist dagegen nicht brauchbar für kleine Maschinen, bei denen innerhalb der Kolbenbolzenbohrung nicht genügend Platz vorhanden ist, um die Sicherungsmutter aufzuschrauben und den Splint einzustecken.The invention relates to a backup of the piston pin in internal combustion engines that is particularly suitable for aluminum pistons where thread cannot be used. It is already known to connect the tubular piston pin to the piston through a die to connect both parts penetrating pin, which is inside the piston pin bore is secured by means of a nut screwed onto the bolt and a split pin. Such a connection is only suitable for larger designs, however, is against it not usable for small machines where inside the piston pin bore there is not enough space to screw on the lock nut and the Insert the split pin.
Gemäß der Erfindung wird eine sichere Verbindung des Kolbens mit dem Kolbenbolzen auch für kleinste Ausführungen dadurch ermöglicht, daß der die beiden Teile durchdringende zylindrische oder kegelförmige Stift durch einen federnden Draht gesichert ist, der durch Drehung des Bolzens zum Einschnappen in eine Ringnut am Kolbenbolzen gebracht werden kann.According to the invention, there is a secure connection between the piston and the piston pin even for the smallest designs made possible by the fact that the cylindrical or conical shape penetrating the two parts The pin is secured by a resilient wire that snaps into place by turning the bolt can be brought into an annular groove on the piston pin.
. Diese Verbindung ist außerdem wesentlich billiger als die bekannte und ermöglicht eine sehr leichte und bequeme Montage.. This connection is also much cheaper than the known one and enables one very easy and convenient assembly.
In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung mit konischem Stift dargestellt, und zwar zeigt Abb. 1 einen Längsschnitt durch einen Teil des Kolbens und des Kolbenbolzens an der Verbindungsstelle, Abb. 2 einen Querschnitt nach der Linie I-I der Abb. r.In the drawing is an example embodiment of the invention with a conical Shown pin, namely Fig. 1 shows a longitudinal section through part of the piston and the piston pin at the connection point, Fig. 2 a cross section along the line I-I of Fig. r.
