Abstract
Description
Die Erfindung betrifft ein Kopflager eines Schwingungsdämpfers gemäß den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a head bearing of a vibration damper according to the features of the preamble of claim 1.
Ein
derartiges Kopflager ist aus der
Aufgabe der Erfindung ist es, ein Kopflager für Schwingungsdämpfer anzugeben, welches ein verbessertes Dämpfungsverhalten aufweist.task the invention is to provide a head bearing for vibration damper, which an improved damping behavior having.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Kopflagers sind in den Unteransprüchen angegeben.These The object is solved by the features of claim 1. advantageous Embodiments of the head bearing according to the invention are in the dependent claims specified.
Herkömmliche Kopflager stellen einen Kompromiss dar. Einerseits sollen sie die von der Kolbenstange des Schwingungsdämpfers übertragenen Schwingung durch Fahrbahnanregungen möglichst gut dämpfen. Andererseits müssen sie insbesondere radiale Kräfte nahezu steif am Fahrzeugaufbau abstützen.conventional Head bearings are a compromise dar from the piston rod of the vibration damper transmitted vibration Roadway suggestions as well as possible dampen. On the other hand they in particular radial forces Support almost stiff on the vehicle body.
Grundgedanke des erfindungsgemäßen Kopflagers ist es daher, diese beiden Funktionen eines Schwingungsdämpferkopflagers voneinander zu trennen. Dies wird dadurch erreicht, daß zwischen der Kolbenstange des Schwingungsdämpfers und einem relativ steifen Elastomerlager eine Einrichtung angeordnet ist, die eine Lagerung umfasst, in der die Kolbenstange axial beweglich geführt wird. Über die axiale Beweglichkeit werden Schwingungsanregungen, die über die Kolbenstange des Schwingungsdämpfers in das Kopflager eingebracht werden, vom Elastomerlager entkoppelt.basic idea of the head bearing according to the invention It is therefore, these two functions of a vibration damper head bearing separate from each other. This is achieved in that between the Piston rod of the vibration damper and a relatively stiff elastomeric bearing means is that includes a bearing in which the piston rod is axially movable guided becomes. about the axial mobility are vibrational excitations that over the Piston rod of the vibration damper be introduced into the head bearing, decoupled from the elastomer bearing.
In Ausgestaltung der Erfindung umfasst die Einrichtung zwischen Kolbenstange und Elastomerlager eine Lagerung, die eine Schwenkbewegung der Kolbenstange um ihre Mittelachse erlaubt. Dadurch kann die Kolbenstange Schwenkbewegungen mitmachen, die beispielsweise durch ein gelenktes Fahrzeugrad hervorgerufen werden.In Embodiment of the invention comprises the device between the piston rod and elastomeric bearings a bearing, which pivotal movement of the piston rod allowed around its central axis. This allows the piston rod pivoting movements join in, for example, caused by a steered vehicle become.
In weiterer Ausgestaltung der Erfindung wird die Lagerung der Kolbenstange in der Einrichtung durch Wälzkörper in Form von in einem Kugelkäfig geführten Kugeln einer Kugelbüchse übernommen. Derartige Kugelbüchsen sind sehr kompakt und beanspruchen daher lediglich einen geringen Bauraum.In Another embodiment of the invention, the storage of the piston rod in the facility through rolling elements in Shape of balls guided in a ball cage taken over a ball bush. such bushings are very compact and therefore require only a small amount Space.
Ein Ausführungsbeispiel des erfindungsgemäßen Kopflagers wird anhand der Zeichnung nachfolgend näher erläutert.One embodiment of the head bearing according to the invention will be explained in more detail with reference to the drawing below.
Dabei zeigt die einzige Figur eine schematische Darstellung eines Längsschnitts durch ein erfindungsgemäßes Kopflager. Zur übersichtlicheren Darstellung sind nicht alle geschnitten dargestellten Bauteile mit Schraffur versehen. Die das Kopflager umgebenden Bauteile sind lediglich gestrichelt dargestellt.there the single figure shows a schematic representation of a longitudinal section by a head bearing according to the invention. For a clearer Representation are not all cut components shown with Hatching provided. The components surrounding the head bearing are merely shown in dashed lines.
