Die Erfindung betrifft einen doppel-T-förmigen Kolbenbolzen mit einem zwei Flansche verbindenden Bolzensteg. The invention relates to a double-T-shaped piston pin with a pin web connecting two flanges.
Aus der DE-OS 33 31 300 ist es bekannt, zur Verbindung zwischen einem Kolben und einem Pleuel einen doppel-T-förmigen Kolbenbolzen zu verwenden. Die Ausgestaltung mit einer konstanten Bolzenstegbreite und mit konstanten Flanschhöhen hat jedoch den Nachteil, daß es in den Übergangsbereichen zwischen Kolbenaugen und Pleuel infolge von Spannungsmaximas zu Verformungen des Kolbenbolzens kommen kann, welche eine einwandfreie Führung in den Kolbenaugen oder gegebenenfalls irn kleinen Pleuelauge verhindern, so daß ein schneller Verschleiß der Führungsflächen zu erwarten ist.From DE-OS 33 31 300 it is known to connect to use a double-T-shaped piston pin between a piston and a connecting rod. the However, design with a constant bolt web width and with constant flange heights has the disadvantage that it increases in the transition areas between the piston bosses and the connecting rod as a result of stress maxima Deformations of the piston pin can occur, which allow proper guidance in the piston bosses or if necessary prevent in the small connecting rod eye, so that a faster wear of the guide surfaces to is expected.
Der Erfindung liegt daher die Aufgabe zugrunde, den aus der DE-OS 33 31 300 vorbekannten doppel-T-förmigen Kolbenbolzen derart zu verbessern, daß bei einem minimalen Gewicht eine größtmögliche Steifigkeit des Bolzens erzielt wird.The invention is therefore based on the object of the previously known from DE-OS 33 31 300 double-T-shaped To improve the piston pin in such a way that the greatest possible rigidity with a minimal weight of the bolt is achieved.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Bolzen im Bereich der Übergänge von den Kolbenaugen zum Pleuel Verstärkungen besitzt.The object is achieved according to the invention in that the bolt in the area of the transitions from the piston bosses has reinforcements to the connecting rod.
Durch diese Verstärkungen wird der Kolbenbolzen in den Bereichen größter Belastung versteift, wodurch Verformungen des Bolzens infolge der Gas- und Massenkräfte verhindert werden. Weiter werden in diesen Bereichen größter Belastung, die Oberflächen der Gleitflächen im Kolbenauge bzw. kleinen Pleuelauge vergrößert und damit die Flächenpressung zur Reduzierung des Verschleißes verringert.Due to these reinforcements, the piston pin is stiffened in the areas of greatest load, whereby Deformations of the bolt as a result of the gas and inertia forces can be prevented. Next will be in this Areas of greatest stress, the surfaces of the sliding surfaces in the piston eye or small connecting rod eye enlarged and thus the surface pressure is reduced to reduce wear.
Die konkave Ausbildung der beiden Stirnflächen bewirkt eine Reduzierung der Kolbenbolzenmasse, ohne jedoch die Festigkeit des Bolzens selbst negativ zu beeinflussen. The concave design of the two end faces reduces the piston pin mass without however, adversely affecting the strength of the bolt itself.
