Description
Die Erfindung bezieht sich auf eine Feder-Dämpfer-Anordnung mit Niveauverstellung nach dem Oberbegriff von Patentanspruch 1.The invention relates to a spring-damper arrangement with level adjustment according to the preamble of
Derartige Feder-Dämpfer-Anordnungen können in Kraftfahrzeugen zur Niveauregulierung eingesetzt werden. So kann beispielsweise die Bodenfreiheit eines Fahrzeugs bei unterschiedlichen Beladungszuständen konstant gehalten werden. Eine weitere Einsatzmöglichkeit besteht darin, das Niveau des Fahrzeugsaufbaus über der Fahrbahn an unterschiedliche Fahrbedingungen anzupassen. Möglich ist beispielsweise eine Niveauabsenkung bei höheren Fahrgeschwindigkeiten. Die Niveauverstellung kann auch dynamisch erfolgen, um Nick- und Wankbewegungen zu dämpfen bzw. auszugleichen. Entsprechende Systeme werden mitunter als Aktive Body Control bzw. ABC-Systeme bezeichnet. Such spring-damper arrangements can be used in vehicles for level control. For example, the ground clearance of a vehicle can be kept constant at different loading conditions. Another possible use is to adjust the level of the vehicle body above the road to different driving conditions. Possible, for example, a level reduction at higher speeds. The level adjustment can also be done dynamically to dampen or compensate for pitching and rolling movements. Corresponding systems are sometimes referred to as Active Body Control or ABC systems.
Die Niveauverstellung über die Verlagerung eines Federtellers der Federanordnung ist aus dem Stand der Technik allgemein bekannt. The level adjustment on the displacement of a spring plate of the spring assembly is well known in the art.

Der Erfindung liegt die Aufgabe zu Grunde, den Aufbau einer solchen Feder-Dämpfer-Anordnung mit Niveauverstellung unter Berücksichtigung fertigungstechnischer Gesichtspunkte zu vereinfachen.The invention is based on the object to simplify the construction of such a spring-damper assembly with level adjustment, taking into account manufacturing aspects.
Diese Aufgabe wird durch eine Feder-Dämpfer-Anordnung mit den Merkmalen von Patentanspruch 1 gelöst. Der Federteller und der Antrieb desselben lassen sich hierdurch einfacher herstellen. This object is achieved by a spring-damper arrangement having the features of
Vorteilhafte Ausgestaltungen sind Gegenstand weiterer Patentansprüche.Advantageous embodiments are the subject of further claims.
In vorteilhafter Ausgestaltung kommt an dem Federteller ein Kugel-Gewinde-Trieb zum Einsatz.In an advantageous embodiment, a ball screw drive is used on the spring plate.
Die bevorzugte Verwendung eines Hohlankermotors koaxial zur Kolbenstange des Schwingungsdämpfers ermöglicht eine platzsparende Anordnung der Antriebseinrichtung.The preferred use of a hollow armature motor coaxial with the piston rod of the vibration damper allows a space-saving arrangement of the drive device.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in:The invention will be explained in more detail with reference to an embodiment shown in the drawing. The drawing shows in:
