Description
Die Erfindung bezieht sich auf einen Pralidämpfer für Kraftfahrzeuge, insbesondere zur Abstützung eines Stoßfängers eines Kraftfahrzeuges an dessen Chassis, gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a shock absorber for motor vehicles, in particular for support a bumper one Motor vehicle on the chassis, according to the preamble of the claim 1.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Pralldämpfer der gattungsgemäßen Art so auszugestalten, daß die Gesamtlänge des Pralldämpfers bei gleichbleibender Dämpfungswirkung möglichst gering ist.Of the Invention is therefore the object of an impact damper generic type in such a way that the overall length of the impact absorber with constant damping effect preferably is low.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Der Kern der Erfindung besteht darin, daß das freie Ende des Deformations-Rohres über das freie Ende des Tragrohres entgegen der Einschubrichtung hervorsteht und darin das Gehäuse des reversiblen Aufpralldämpfers verschiebbar geführt ist. Somit ist es nicht erforderlich, einen entsprechenden Abschnitt des Tragrohres zur Führung des Gehäuses vorzusehen, wodurch die Gesamtanordnung substantiell verkürzt werden kann.These The object is achieved by the Characteristics of the characterizing part of claim 1 solved. Of the Essence of the invention is that the free end of the deformation tube on the free end of the support tube protrudes counter to the insertion direction and in it the case of the reversible impact absorber slidably guided is. Thus, it is not necessary to have an appropriate section of the support tube for guiding the housing provide, whereby the overall arrangement be substantially shortened can.
Zahlreiche weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.numerous Further advantageous embodiments will become apparent from the dependent claims.
