Abstract
Description
Die Erfindung betrifft einen Nockenwellenversteller für Verbrennungskraftmaschinen von Kraftfahrzeugen nach dem Oberbegriff des Anspruches 1.The Invention relates to a camshaft adjuster for internal combustion engines of motor vehicles according to the preamble of claim 1.
Mit Nockenwellenverstellern wird der Öffnungszeitpunkt von Ein- und Auslaßventilen der Verbrennungskraftmaschine in Abhängigkeit von der jeweils benötigten Leistung gesteuert. Es bereitet mitunter Probleme, das Ventil in die Verbrennungskraftmaschine des Kraftfahrzeuges einzubauen, da der Platz hierfür nicht ausreicht.With Camshaft adjusters will be the opening time of input and exhaust the internal combustion engine depending on the power required controlled. Sometimes the valve in the internal combustion engine causes problems to install the motor vehicle, since the space for this is not sufficient.
Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Nockenwellenversteller so auszubilden, daß er auch bei beengten Platzverhältnissen im Kraftfahrzeug eingesetzt werden kann.The The invention is based on the object of the generic camshaft adjuster to train so that he even in confined spaces can be used in the motor vehicle.
Diese Aufgabe wird beim gattungsgemäßen Nockenwellenversteller erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This The task is with the generic camshaft adjuster according to the invention with the characteristic Features of claim 1 solved.
Beim erfindungsgemäßen Nockenwellenversteller ist das Ventil an der vom Nockenwellenanschluß abgewandten Seite angeordnet. Darum kann das Ventil axial außerhalb des Motors ortsfest angeordnet werden. Der erfindungsgemäße Nockenwellenversteller benötigt darum nur wenig Einbauraum. Außerdem läßt sich der erfindungsgemäße Nockenwellenversteller auch nachträglich anbauen.At the camshaft adjuster according to the invention the valve is arranged on the side facing away from the camshaft connection. Therefore the valve can be axially outside of the motor can be arranged in a fixed position. The camshaft adjuster according to the invention needed therefore little installation space. Moreover let yourself the camshaft adjuster according to the invention also afterwards plant.
Bei einer anderen Ausbildung ist das Ventil wenigstens teilweise innerhalb des Nockenwellenverstellers untergebracht. Dadurch wird für das Ventil in der Verbrennungskraftmaschine kein zusätzlicher Einbauraum benötigt.at In another embodiment, the valve is at least partially inside of the camshaft adjuster. This will in for the valve the internal combustion engine requires no additional installation space.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further Features of the invention result from the further claims that Description and the drawings.
