Abstract
Description
Die
vorliegende Erfindung betrifft einen Lenkaktuator gemäß dem Oberbegriff
des Anspruchs 1. Weiterhin ist die Erfindung auf eine Fahrzeuglenkanordnung
mit einem solchen Lenkaktuator gerichtet.The
The present invention relates to a steering actuator according to the preamble
of
Bei den bekannten am Markt befindlichen EPS (Electric Power Steering) Systemen mit Antrieb über Gewindemutter und Gewindespindel erfolgt die Umsetzung der Drehbewegung des Lenkrades in eine der Lenkaktion entsprechende Axialbewegung über eine axial fixierte, mittels Hohlwellenmotor oder über Zahnriementrieb angetriebene Gewindemutter und eine axial bewegliche, gegen Verdrehung gesicherte Hubspindel. In dieser Konfiguration muss die Mutter axial fixiert und die Spindel gegen Verdrehung gesichert werden. Dies erhöht den Bauraumbedarf, erfordert zusätzliche Bauteile (Gewindemutter, Elemente zur Verdrehsicherung, Führungselemente, Wälzlager, ...) und bewirkt unerwünschte Reibungswiderstände.at known EPS (Electric Power Steering) available on the market Systems with drive over Threaded nut and threaded spindle is the implementation of the rotational movement the steering wheel in a steering action corresponding axial movement over a axially fixed, driven by hollow shaft motor or toothed belt drive Threaded nut and an axially movable, secured against rotation Jack screw. In this configuration, the nut must be axially fixed and the spindle can be secured against rotation. This increases the space requirement, requires additional Components (threaded nut, anti-rotation elements, guide elements, roller bearings, ...) and causes unwanted Frictional resistance.
Es ist eine Aufgabe der Erfindung, die genannten Nachteile zu beseitigen.It An object of the invention is to eliminate the disadvantages mentioned.
Erfindungsgemäß wird diese
Aufgabe durch einen Lenkaktuator mit den Merkmalen des Anspruchs
1 gelöst.According to the invention this
Task by a steering actuator with the features of the
Mit dem erfindungsgemäßen Lenkaktuator werden Komplexität, Bauraum, Gewicht und Kosten gegenüber bekannten EPS Lenksystemen, insbesondere von solchen mit EAFS-Funktion (Aktivlenkung) reduziert. Außerdem wird eine Wirkungsgraderhöhung durch die Verwendung von elektrischen Systemen, die bei Bedarf aktiviert werden, erreicht.With be the steering actuator according to the invention Complexity, Space, weight and costs compared to known EPS steering systems, especially reduced by those with EAFS function (active steering). Furthermore becomes an increase in efficiency through the use of electrical systems that activate when needed be achieved.
Durch die Spindellagerung über das Bewegungsgewinde im Lenkgehäuse wird erstmals eine Lösung mit rotierender und zugleich axial bewegter Antriebsspindel realisiert. Durch die ”Steer-by-wire”-Tauglichkeit, den einfachen Aufbau und die optionale AFS-Ausstattung eröffnet sich ein großes Einsatzgebiet. Durch den optionalen koaxialen Antrieb ist der Lenkaktuator auch für Fahrzeuge mit hohen Spurstangenkräften geeignet und eine sehr kompakte Bauweise möglich. Eine Ausführung der Antriebsspindel als Kugelgewindespindel zur Erhöhung des Wirkungsgrades ist möglich.By the spindle bearing over the movement thread in the steering housing becomes a solution for the first time realized with rotating and axially moving drive spindle. Through the steer-by-wire capability, The simple structure and the optional AFS equipment opens up a big Operation area. The optional coaxial drive is the steering actuator also for Vehicles with high tie rod forces suitable and a very compact design possible. An execution the drive spindle as a ball screw to increase the efficiency is possible.
Der Lenkaktuator ist prinzipiell bei einer Vorderradlenkung wie auch bei einer Hinterradlenkung einsetzbar.Of the Steering actuator is basically a front-wheel steering as well used in a rear-wheel steering.
Vorteilhafte Ausführungsformen sind in den Unteransprüchen angegeben.advantageous embodiments are in the subclaims specified.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Bezugnahme auf die Figuren näher beschrieben.The Invention will now be described with reference to exemplary embodiments with reference closer to the figures described.
