Abstract
Description
Die Erfindung betrifft eine elektrische Servolenkung, insbesondere eine Hilfskraftlenkung für ein Fahrzeug, nach dem Oberbegriff des Anspruchs 1.The The invention relates to an electric power steering, in particular a Power steering system for a vehicle, according to the generic term of claim 1.
Die
Die
Radial an einem Lagergehäuse des Kugelgewindetriebes sind zahlreiche Einfüllbohrungen für die Kugeln angeordnet, die mit einer Vielzahl von Stopfen verschlossen sind.Radial on a bearing housing of the ball screw are numerous Filling holes arranged for the balls, the are closed with a variety of plugs.
Der Kugelgewindetriebe ist aufwändig gebaut.Of the Ball screws are elaborately built.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach zu montierende elektrische Servolenkung zu schaffen.Of the Invention is based on the object, an easy to install to provide electric power steering.
Die Aufgabe wird mit einer elektrischen Servolenkung mit den Merkmalen des Anspruchs 1 gelöst.The Task is with an electric power steering with the features of claim 1.
Dadurch dass in der Mutter der elektrischen Servolenkung eine einzige Einfüllbohrung vorgesehen ist, ist eine einfache Möglichkeit der Montage und Befüllung des Kugelschraubgetriebes der elektrischen Servolenkung gegeben.Thereby that in the mother of the electric power steering a single filler hole is provided, is an easy way of mounting and Filling the ball screw transmission of the electric power steering where.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
In einem besonders bevorzugten Ausführungsbeispiel ist die Einfüllbohrung durch die Gehäusewand zur Mutter geführt.In a particularly preferred embodiment is the Filling hole through the housing wall to the nut guided.
Die Erfindung wird nun näher anhand eines Ausführungsbeispiels beschrieben und anhand der beiliegenden Zeichnung wiedergegeben.The Invention will now be closer with reference to an embodiment described and reproduced with reference to the accompanying drawings.
