Abstract

The invention relates to a I-shaped gudgeon pin made of a steel material, which is manufactured from a section-rolled or extruded raw material.

Description

"Doppel-T-förmiger Kolbenbolzen aus"Double T-shaped piston pin made

einem Stahlwerkstoff" Die Erfindung betrifft einen doppel-T-förmigen Kolbenbolzen aus einem Stahlwerkstoff. a steel material "The invention relates to a double-T-shaped Piston pin made from a steel material.

Aus der DE-OS 33 31 300 ist es bekannt zur Verbindung zwischen Kolben und Pleuel einen doppel-T-formigen Kolbenbolzen zu verwenden. Über die Herstellung eines Kolbenbolzens dieser Form wird in der genannten Druckschrift nichts ausgesagt.From DE-OS 33 31 300 it is known for the connection between pistons and connecting rods to use a double-T-shaped piston pin. About the manufacture a piston pin of this shape is not stated in the cited document.

Der Erfindung liegt daher die Aufgabe zugrunde für den bekannten doppel-T-förmigen Kolbenbolzen eine Möglichkeit aufzuzeigen, mittels der der Bolzen bei pptimalen Festigkeitseigenschaften kostengünstig hergestellt werden kann.The invention is therefore based on the object for the known double-T-shaped Piston pin to show a possibility by means of which the pin at pptimalen Strength properties can be produced inexpensively.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kolbenbolzen aus einem profilgewaiten oder fließgepressten Rohmaterial hergestellt ist.The object is achieved according to the invention in that the piston pin is made from a profiled or extruded raw material.

Ein durch Profilwalzen oder Fließpressen hergestellter doppel-T-förmiger Kolbenbolzen'hat zum einen den Vorteil, daß nur noch dessen äußere Flanschflächen, welche mit den Gleitflächen im Kolbenauge bzw. im Pleuelauge in Berührung stehen, feinstbearbeitet werden müssen, und zum anderen wird durch das Walzen bzw. Fließpressen zur Oberfläche des Bolzens hin ein Verdichten der Werkstoffasern erzielt, was zu einer Erhöhung der Festigkeit, vor allem im Bereich des stark belasteten Bolzensteges führt.A double T-shape made by roll forming or extrusion On the one hand, the piston pin has the advantage that only its outer flange surfaces, which are in contact with the sliding surfaces in the piston eye or in the connecting rod eye, must be finely machined, and on the other hand is made by rolling or extrusion towards the surface of the bolt compresses the material fibers achieved, resulting in an increase in strength, especially in the area of the heavily loaded Bolt web leads.

Die Verwendung eines stangenförmigen Rohmaterials ermöglicht eine kostengünstige Herstellung des Kolbenbolzens.The use of a rod-shaped raw material enables one inexpensive manufacture of the piston pin.

Die Zeichnung zeigt einen erfindungsgemäßen doppel-T-förmigen Kolbenbolzen in einer perspektivischen Darstellung.The drawing shows a double-T-shaped piston pin according to the invention in a perspective view.

Der in der Zeichnung dargestellte doppel-T-förmige Kolbenbolzen 1 besteht aus einem Bolzensteg 2 und zwei Bolzenflanschen 3 und 4 mit je zwei Flanschinnenflächen 5 und 6 und je einer Flanschaußenfläche 7 und 8, wobei die Flanschinnenflächen 6 gegenüber einer Horizontalen 9 eine Neigung aufweisen, damit bei der Verwendung eines klauenartig ausgebildeten Pleueloberteils an den Stellen 10 die Probleme infolge Kerbwirkungen verringert werden.The double-T-shaped piston pin 1 shown in the drawing consists of a bolt web 2 and two bolt flanges 3 and 4, each with two inner flange surfaces 5 and 6 and one outer flange surface 7 and 8 each, the inner flange surfaces 6 have an inclination with respect to a horizontal 9, so that in use a claw-like connecting rod upper part at the points 10 the problems as a result Notch effects are reduced.

Aus einem beispielsweisen rechteckigen stangenförmigen Rohmaterial wird diesem durch Profilwalzen oder Fließpressen im kalten oder warmen Zustand eine doppel-T-Form gegeben. Für eine möglichst maßgenaue Formgebung kann auch ein Kalibrierwalzen bzw. Kalibrierfließpressen nachgeschaltet sein. Anschließend wird das umgeformte Stangenmaterial auf Bolzenlänge gestückelt. Zur Gewährleistung optimaler Laufeigenschaften des Kolbenbolzens 1 in den Kolbenaugen eines Kolbens bzw. Pleuelauge eines Pleuels werden die äußeren Flanschflächen 7 und 8 noch feinstbearbeitet.From a, for example, rectangular rod-shaped raw material this is achieved by profile rolling or extrusion in the cold or warm state given a double T shape. Calibrating rollers can also be used for shaping that is as dimensionally accurate as possible or calibrating extrusion can be connected downstream. Then the reshaped Bar material cut to the length of the bolt. To ensure optimal running properties of the piston pin 1 in the piston bosses of a piston or connecting rod bosses of a connecting rod the outer flange surfaces 7 and 8 are still finely machined.
