Abstract
Description
Die Erfindung betrifft eine Nockenwellenverstelleinrichtung für Verbrennungskraftmaschinen von Kraftfahrzeugen nach dem Oberbegriff des Anspruches 1.The The invention relates to a camshaft adjusting device for internal combustion engines of motor vehicles according to the preamble of claim 1.
Solche Nockenwellenverstelleinrichtungen haben die Aufgabe, die Öffnungs- und Schließzeitpunkte der Gaswechselventile durch eine Relativverdrehung der Nockenwelle gegenüber der Kurbelwelle zu verschieben. Die Rotor- und die Statorflügel liegen mit ihren Stirnseiten an den jeweiligen Gegenflächen des Stators bzw. Rotors an. Zur Relativverstellung wird Hydraulikmedium eingesetzt, das die Rotorflügel von beiden Seiten so beaufschlagen kann, daß der Rotor in der gewünschten Richtung relativ zum Stator gedreht wird. Damit ein Leckagestrom des Hydraulikmediums zwischen den aneinanderliegenden Flächen reduziert wird, müssen die Rotor- bzw. Statorflügel mit ihren Stirnseiten dichtend an den Gegenflächen anliegen.Such Camshaft adjusting devices have the task of opening the and closing times the gas exchange valves by a relative rotation of the camshaft across from to move the crankshaft. The rotor and stator blades are included their end faces on the respective mating surfaces of the stator or rotor at. For relative adjustment hydraulic medium is used, the the rotor blades of both sides can act so that the rotor in the desired Direction is rotated relative to the stator. So that a leakage current reduces the hydraulic medium between the adjacent surfaces will have to the rotor or stator blades with their front sides sealing against the opposite surfaces.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Nokkenwellenverstelleinrichtung so auszubilden, daß sie bei einfacher und kostengünstiger Herstellung zuverlässig arbeitet.Of the Invention is based on the object, the generic Nokkenwellenverstelleinrichtung to train them at simpler and cheaper Reliable production is working.
Diese Aufgabe wird bei der gattungsgemäßen Nockenwellenverstelleinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.These Task is in the generic camshaft adjustment according to the invention with the characterizing features of claim 1 solved.
Die Nockenwellenverstelleinrichtung weist die Abrißkanten auf, mit denen ein eventuell auftretender Leckagestrom optimal vermindert wird.The Camshaft adjusting device has the Abrißkanten, with which a possibly occurring leakage current is optimally reduced.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further Features of the invention will become apparent from the other claims, the Description and the drawings.
Die Erfindung wird anhand einiger in den Zeichnungen dargestellter Ausführungsformen näher erläutert. Es zeigenThe The invention will be described with reference to some embodiments shown in the drawings explained in more detail. It demonstrate
