Abstract
Description
Die Erfindung bezieht sich auf das Gebiet der Fahrzeugtechnik und insbesondere auf einen Schwingungsdämpfer bzw. ein Verfahren zur Herstellung eines Schwingungsdämpfers für eine Radaufhängung.The The invention relates to the field of vehicle technology and in particular on a vibration damper or a method for producing a vibration damper for a suspension.
Derartige Schwingungsdämpfer weisen in der Regel ein durch einen Behälterboden abgeschlossenes Behälterrohr auf, das über ein Lager an einer Radführungskomponente gelenkig abgestützt ist. Hierzu ist an dem Schwingungsdämpfer eine Lageraufnahme in Form eines Lagerauges vorgesehen. Üblicherweise ist das Lagerauge an den Behälterboden angeschweißt. Da Schwingungsdämpfer hohen Beanspruchungen ausgesetzt sind, muss die Schweißnaht zwischen dem Lagerauge und dem Behälterboden mit hoher Güte ausgeführt werden, um Schäden zu vermeiden. Die Anbindung der Lageraufnahme ist dementsprechend aufwändig.such vibration usually have a closed by a container bottom container tube on that over a bearing on a Radführungskomponente is supported articulated. This is due to the vibration damper provided a bearing support in the form of a bearing eye. Usually is the bearing eye to the tank bottom welded. Because vibration damper exposed to high stresses, the weld must be between the bearing eye and the container bottom with high quality accomplished be to damage to avoid. The connection of the bearing receiver is accordingly consuming.
Der Erfindung liegt die Aufgabe zugrunde, hier Abhilfe zu schaffen.Of the Invention is based on the object to remedy this situation.
Diese Aufgabe wird durch einen Schwingungsdämpfer gemäß Patentanspruch 1 bzw. durch ein Verfahren zur Herstellung eines Schwingungsdämpfers gemäß Patentanspruch 20 gelöst. Der erfindungsgemäße bzw. erfindungsgemäß hergestellte Schwingungsdämpfer zeichnet sich dadurch aus, dass der Behälterboden und das Lagerauge in ein Blechformteil integriert sind, das aus einem Stück besteht.These Task is achieved by a vibration damper according to claim 1 or by a A method for producing a vibration damper according to claim 20 solved. Of the according to and characterized inventively vibration damper draws characterized by the fact that the container bottom and the bearing eye are integrated into a sheet metal part, the one piece consists.
Die Lageraufnahme und der Behälterboden bestehen somit nur noch aus einem einzigen Blechteil. Hierdurch wird die Anzahl der Bauteile verringert, woraus eine Reduzierung des Füge-, Handhabungs- und Logistikaufwands resultiert.The Bearings and the container bottom consist thus only from a single sheet metal part. This will be the Reduced number of components, resulting in a reduction of the joining, handling and Logistics expenses results.
Zudem wird die Gefahr von Ausfällen verringert, da in dem hochbeanspruchten Bereich zwischen dem Lagerauge und dem Behälterboden keine Schweißnaht mehr vorhanden ist. Im Vergleich zu geschweißten Verbindungen wird eine erhöhte Bauteilfestigkeit erzielt.moreover will be the danger of failures reduced, since in the highly stressed area between the bearing eye and the container bottom no weld more is available. Compared to welded connections, a increased Component strength achieved.
