To the leakage of contact area is probably already larger. This advantage can lubricate oil from the piston pin bore 4 and the but according to the invention are still significantly increased to prevent lateral displacement of the piston pin that the cover is on a part of its area, the bore is in a known manner on both sides at the beginning flattened on one side and closed with a lid 5 to the inside. These will be inventive Boundary edges of the flattened area are paralleled by resilient, strip-shaped clamping plates 6 running groove are provided, in which a clamped against corresponding annular surfaces 7 on the piston Condition curved, strip-shaped clamping presses.

Fig. 3 shows a side view of the clamping plate in the removed The installation of the piston pin retainer is done built condition, in the manner described below:
Nach Einbringen des Kolbenbolzens 2 in die Kolbenbolzenbohrung wird der Deckel 5 in die Bohrung 4 eingelegt, welche an ihrem Ende eine ringförmige Auflagefläche 7 besitzt. Auf dem Deckel ist dabei die Spannplatte 6 mittels eines Bügels 14 und einer Schraube 15 eben angepreßt. Das Einführen des Dekkels mit der Spannplatte erfolgt in der Fig. 4 dargestellten Lage der Spannplatte durch den zwischen der oberen und unteren Hälfte der Nut 10 gebildeten Spalt, der etwas breiter als die Spannplatte ist. Nach Verdrehen des Deckels greifen die gebogenen Kanten der Spannplatte in die Nuten 10 am Kolben und verriegeln die Platte mit dem Deckel durch Einschnappen des Lappens 9 in die Ausnehmung 11 in einer in Fig. 6 dargestellten Lage, sobald durch Lösen der Schraube 15 die Lappen ihre ursprüngliche Lage zur Platte wieder einnehmen. Der Ausbau der Kolbenbolzensicherung geschieht in ähnlicher Weise. Durch entsprechende Bemessung der Spannplattenbreite kann die Anpreßkraft den jeweiligen Erfordernissen angepaßt werden.After the piston pin 2 has been inserted into the piston pin bore, the cover 5 is inserted into the bore 4 inserted, which has an annular support surface 7 at its end. On the lid is the Clamping plate 6 pressed on by means of a bracket 14 and a screw 15. Insertion of the lid with the clamping plate takes place in Fig. 4 shown position of the clamping plate through the between the upper and lower half of the groove 10 formed gap which is slightly wider than the clamping plate. To By turning the cover, the curved edges of the clamping plate engage in the grooves 10 on the piston and lock the plate with the lid by snapping the tab 9 into the recess 11 in an in Fig. 6 position shown as soon as by loosening the screw 15, the tabs their original position to Take the plate again. The removal of the piston pin retainer is done in a similar way. By Appropriate dimensioning of the clamping plate width can adapt the contact pressure to the respective requirements will.
