Abstract
Description
Die Erfindung betrifft eine Pleuellagerung nach dem Oberbegriff des Anspruchs 1.The invention relates to a connecting rod bearing according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine besonders vorteilhafte Pleuellagerung für ein wälzgelagertes Pleuel zu erreichen. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of achieving a particularly advantageous Pleuellagerung for a roller-mounted connecting rod. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einem Pleuel für eine Brennkraftmaschine eines Kraftfahrzeugs, mit einer Pleuellagerung für eine Lagerung auf einer Kurbelwelle, die zur axialen Lagerung zumindest eine axiale Lagerfläche aufweist.The invention relates to a connecting rod for an internal combustion engine of a motor vehicle, with a connecting rod bearing for a bearing on a crankshaft, which has at least one axial bearing surface for the axial bearing.
Es wird vorgeschlagen, dass die axiale Lagerfläche der Pleuellagerung zumindest eine, sich von einer Fase unterscheidende, hydrodynamisch wirksame Formfläche aufweist. Dadurch kann die Lagerfläche vorteilhaft einen Schmierfilm aufbauen, wodurch das Pleuel axial besonders vorteilhaft und verschleißfrei und reibungsarm gelagert werden kann. Unter einer „Fase” soll dabei insbesondere eine Fase verstanden werden, die zumindest einen Winkel von 10 Grad zwischen einer in axialer Richtung senkrechten Wandung einer Nut und einer abgeschrägten Fläche, und eine Höhe, die von in axialer Richtung von einem unteren Ende der abgeschrägten Fläche bis zu einem oberen Ende der abgeschrägten Fläche gemessen wird, von zumindest 0,4 mm aufweist. Unter einer „hydrodynamisch wirksamen Formfläche” soll insbesondere eine Fläche verstanden werden, die dazu vorgesehen ist, aktiv einen Schmierfilm aufzubauen.It is proposed that the axial bearing surface of the conrod bearing has at least one hydrodynamically effective shaping surface which differs from a chamfer. As a result, the bearing surface can advantageously build up a lubricating film, whereby the connecting rod can be axially stored particularly advantageously and wear-free and with low friction. A "chamfer" is to be understood in particular as a chamfer having at least an angle of 10 degrees between an axially perpendicular wall of a groove and a chamfered surface, and a height from the axial direction of a lower end of the chamfered surface is measured to an upper end of the tapered surface of at least 0.4 mm. A "hydrodynamically effective shaping surface" is to be understood as meaning, in particular, a surface which is intended to actively build up a lubricating film.
Weiter wird vorgeschlagen, dass die zumindest eine hydrodynamisch wirksame Formfläche als eine Rampe ausgebildet ist, die eine Höhe von höchstens 0,3 mm aufweist. Dadurch kann eine besonders vorteilhafte Formfläche erreicht werden. Unter einer „Rampe” soll dabei insbesondere eine in axialer Richtung geneigte Fläche verstanden werden, die ein axial oberes Ende und ein axial unteres Ende aufweist, die über eine Rampenfläche miteinander verbunden sind. Die Rampenfläche ist dabei vorzugsweise als eine ebene Fläche ausgebildet, kann aber grundsätzlich auch als eine ballige Fläche ausgebildet sein. Unter einer „Höhe der Rampe” soll dabei insbesondere eine axiale Ausdehnung der Rampe verstanden werden, die sich in axialer Richtung von einem unteren Ende der Rampe, an der eine Nut in die Rampenfläche übergeht, bis zu einem oberen Ende der Rampe, an der die Rampenfläche in die axiale Lagerfläche übergeht, erstreckt.It is further proposed that the at least one hydrodynamically effective shaping surface is designed as a ramp which has a height of at most 0.3 mm. As a result, a particularly advantageous molding surface can be achieved. A "ramp" is to be understood in particular as an inclined surface in the axial direction, which has an axially upper end and an axially lower end, which are connected to one another via a ramp surface. The ramp surface is preferably formed as a flat surface, but may in principle be formed as a spherical surface. A "height of the ramp" is to be understood in particular as an axial extent of the ramp, which extends in the axial direction from a lower end of the ramp, at which a groove merges into the ramp surface, up to an upper end of the ramp at which Ramp surface merges into the axial bearing surface extends.
Ferner wird vorgeschlagen, dass die zumindest eine hydrodynamisch wirksame Formfläche eine Länge von mindestens 5,0 mm aufweist. Dadurch bildet die als Rampe ausgebildete Formfläche einen besonders vorteilhaften Winkel aus. Unter einer „Länge der Rampe” soll dabei insbesondere eine in Umfangsrichtung gerichtete Ausdehnung der Rampe verstanden werden, die sich in Umfangsrichtung von einem unteren Ende der Rampe, an der eine Nut in die Rampenfläche übergeht, bis zu einem oberen Ende der Rampe, an der die Rampenfläche in die axiale Lagerfläche übergeht, erstreckt.It is also proposed that the at least one hydrodynamically effective shaping surface has a length of at least 5.0 mm. As a result, the forming surface formed as a ramp forms a particularly advantageous angle. A "length of the ramp" should be understood to mean, in particular, a circumferential extension of the ramp, which extends in the circumferential direction from a lower end of the ramp, at which a groove merges into the ramp surface, up to an upper end of the ramp the ramp surface merges into the axial bearing surface extends.

Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing.
