Description
Die
Erfindung betrifft eine Pleuelstange für eine Brennkraftmaschine
gemäß dem Oberbegriff des Patentanspruchs 1. Des
Weiteren betrifft die Erfindung ein Verfahren zur Herstellung der
Pleuelstange gemäß dem Oberbegriff des Patentanspruchs
5.The
The invention relates to a connecting rod for an internal combustion engine
according to the preamble of
Die
Die
Die
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Pleuelstange für eine Brennkraftmaschine und ein verbessertes Verfahren zur Herstellung der Pleuelstange anzugeben.Of the Invention is based on the object, an improved connecting rod for an internal combustion engine and an improved method to specify for the production of the connecting rod.
Hinsichtlich
der Pleuelstange wird die Aufgabe erfindungsgemäß durch
die im Anspruch 1 angegebenen Merkmale gelöst. Hinsichtlich
des Verfahrens zur Herstellung der Pleuelstange wird die Aufgabe
erfindungsgemäß durch die im Anspruch 5 angegebenen
Merkmale gelöst.Regarding
the connecting rod according to the invention by
the features specified in
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Further developments of the invention are the subject of the dependent claims.
Bei der erfindungsgemäßen Pleuelstange für eine Brennkraftmaschine mit einem an oder in einem Pleuelfuß angeordneten Pleuelauge zur Verbindung mit einer Kurbelwelle, mit einem Lagerauge zur Verbindung mit einem Kolben und mit einem das Pleuelauge mit dem Lagerauge verbindenden Pleuelschaft, wobei das Pleuelauge an einer Teilungsebene geteilt ist und ein Pleuellagerdeckel mit zwei Verbindungsschrauben mit der Pleuelstange verschraubt ist und zwei abschnittsweise mit einem Innengewinde versehene Sacklochbohrungen in der Pleuelstange angeordnet sind, wobei die Innengewinde der Sacklochbohrungen mit den Außengewinden der Verbindungsschrauben korrespondieren, sind Grundlöcher am Ende der Sacklochbohrungen erfindungsgemäß verrundet.at the connecting rod according to the invention for a Internal combustion engine with a arranged on or in a connecting rod Connecting eye for connection to a crankshaft, with a bearing eye for connection with a piston and with a connecting rod with connecting the bearing eye connecting rod shaft, wherein the connecting rod eye a dividing plane is divided and a connecting rod cap with two Connecting bolts are bolted to the connecting rod and two Sectionally provided with an internal thread blind holes are arranged in the connecting rod, wherein the internal thread of the Blind holes with the external threads of the connecting screws correspond, are blind holes at the end of the blind holes rounded according to the invention.
Dadurch ist eine bei einer herkömmlichen Ausformung der Grundlöcher auftretende Kerbwirkung sicher vermieden und eine Wahrscheinlichkeit einer Rissbildung ist verringert.Thereby is one in a conventional formation of the blind holes safely occurring notch effect and a probability of a Cracking is reduced.
Durch die verringerte Kerbwirkung kann vorteilhafterweise eine maximal übertragbare Last der Pleuelstange vergrößert werden oder das Gewicht der Pleuelstange reduziert werden.By the reduced notch effect can advantageously be a maximum transferable Be increased or the load of the connecting rod Weight of the connecting rod can be reduced.
Die Sicherheit bei einer Verwendung der Pleuelstange ist dadurch vergrößert, dass eine Ausfallwahrscheinlichkeit der Pleuelstange verringert ist.The Safety when using the connecting rod is thereby increased, that a probability of failure of the connecting rod is reduced is.
Beim erfindungsgemäßen Verfahren zur Herstellung einer Pleuelstange für eine Brennkraftmaschine, wobei in der Pleuelstange mehrere Sacklochbohrungen zur Verbindung des Pleuellagerdeckels und des Pleuelschafts mittels Schrauben in den Pleuellagerdeckel und den Pleuelschaft eingebracht werden, werden Grundlöcher am Ende der Sacklochbohrungen erfindungsgemäß verrundet.At the inventive method for producing a Connecting rod for an internal combustion engine, wherein in the Connecting rod several blind holes for connecting the connecting rod bearing cap and the connecting rod shaft by means of screws in the connecting rod bearing cap and the congregation will become basic holes rounded at the end of the blind holes according to the invention.
Durch die Verrundung des Grundlochs der Sacklochbohrung beispielsweise mittels eines Ein- oder Zweilippenbohrers ist die Kerbwirkung auf die Pleuelstange vermieden.By the rounding of the base hole blind hole, for example by means of a one- or two-lip drill, the notch effect on avoided the connecting rod.
Ausführungsbeispiele der Erfindung werden anhand von Zeichnungen näher erläutert.embodiments The invention will be explained in more detail with reference to drawings.
