Abstract
Bei einer Federvorrichtung mit einem Wellrohrkörper (1) zwischen zwei relativ zueinander beweglichen Bauteilen, insbesondere für einen Stoßdämpfer eines Fahrzeugs, schließt sich stirnseitig an den rotationssymmetrischen Wellrohrkörper (1) ein Klemmteil (2) für einen Klemmsitz mit einem der beiden zueinander beweglichen Bauteile (3) an. Das Klemmteil (2) weist im Querschnitt eine von der Kreisform abweichende Gestalt auf.In a spring device with a corrugated pipe body (1) between two relatively movable components, in particular for a shock absorber of a vehicle, the front side of the rotationally symmetrical corrugated pipe body (1) includes a clamping part (2) for a clamping fit with one of the two mutually movable components (3 ) at. The clamping part (2) has a cross-sectional shape deviating from the circular shape.
Description
Die Erfindung betrifft eine Federvorrichtung nach dem Oberbegriff von Anspruch 1.The invention relates to a spring device according to the preamble of
Eine Federvorrichtung dieser Art ist aus der

In der
Die
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Federvorrichtung der eingangs erwähnten Art mit einer vereinfachten Geometrie derart auszubilden, dass konventionelle Dämpferlager bei einem Stoßdämpfer eines Fahrzeuges, ohne besondere Anpassung an die Ausgestaltung der Federvorrichtung verwendet werden können, wobei auch eine Austauschbarkeit der Technologien gewährleistet sein soll.The present invention has for its object to form a spring device of the type mentioned above with a simplified geometry such that conventional damper bearings can be used in a shock absorber of a vehicle, without special adaptation to the design of the spring device, which also ensures interchangeability of the technologies should.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is solved by the features of
Durch die Ausgestaltung der Federvorrichtung mit einem rotationssymmetrischen Wellrohrbereich und einem daran sich anschließenden Klemmteil, das durch den erfindungsgemäßen Klemmsitz mit der Kolbenstange des Stoßdämpfers verbunden ist, können konventionelle Dämpferlager verwendet werden bzw. müssen diese nicht an die Ausgestaltung der erfindungsgemäßen Vorrichtung angepasst werden.Due to the design of the spring device with a rotationally symmetrical corrugated pipe area and a subsequent clamping part, which is connected by the clamping seat according to the invention with the piston rod of the shock absorber, conventional damper bearings can be used or they do not have to be adapted to the configuration of the device according to the invention.
Erfindungsgemäß wird nämlich nunmehr keine Verrastung wie zumeist beim Stand der Technik vorgenommen, sondern lediglich eine Klemmung an der inneren Umfangswand des Dämpferlagers. Hierzu ist es erforderlich, dass das Klemmteil im Querschnitt eine von der Kreisform abweichende Gestalt in Form einer polygonalen oder sternförmigen Ausgestaltung – im Querschnitt gesehen – aufweist. Dabei sollte das Klemmteil in vorteilhafter Weise auch starr ausgeführt sein, damit die Kräfte aus dem elastischen Bereich des Wellrohrkörpers durch den Klemmsitz gut übertragen werden können.In accordance with the invention, no latching is now carried out, as is usually the case in the prior art, but only a clamping on the inner circumferential wall of the damper bearing. For this purpose, it is necessary that the clamping part in cross-section a deviating from the circular shape in the form of a polygonal or star-shaped configuration - seen in cross-section - has. In this case, the clamping part should also be designed to be rigid in an advantageous manner, so that the forces can be transferred well from the elastic region of the corrugated tube body by the clamping seat.
Auch die Demontage ist im Vergleich zu den Lösungen nach dem Stand der Technik einfacher, denn das Klemmteil mit dem darin sich anschließenden Wellrohrkörper muss lediglich aus der Verklemmung gelöst werden.The disassembly is easier compared to the solutions according to the prior art, because the clamping part with the subsequent corrugated tube body must be solved only from the deadlock.
Für eine Montage oder Demontage kann vorgesehen sein, dass der Wellrohrkörper mit seinem Federungsbereich im zusammengelegten Zustand an das Klemmteil angelegt ist.For assembly or disassembly can be provided that the corrugated tube body is applied with its suspension area in the collapsed state to the clamping part.
Zusätzliche erfindungsgemäße Merkmale ergeben sich aus den weiteren Unteransprüchen.Additional features of the invention will become apparent from the further subclaims.
Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig beschrieben.Hereinafter, an embodiment of the invention will be described in principle with reference to the drawing.
Es zeigt:It shows:
Die erfindungsgemäße Vorrichtung ist nachfolgend beispielsweise für einen Stoßdämpfer eines Fahrzeuges mit einer Kolbenstange und einem Zylinder als relativ zueinander bewegliche Bauteile beschrieben.The device according to the invention is described below, for example, for a shock absorber of a vehicle with a piston rod and a cylinder as relatively movable components.
