Description

Gtoßdämpfung für Fahrzeunge Die Prfindung bezieht sich auf Eine einmalig bei Auffahrunfällen wirkende Stoßdämpfung für Fahrzeuge, insbesondere Kraftfahrzeuge. Gtoßdampf für Fahrzeunge The test refers to a one-time Shock absorption for vehicles, in particular motor vehicles, effective in rear-end collisions.

Bekannt sind neben hydraulischen Dämpfern stoßdämpfende Glieder in Form von speziell angeordneten Knickstäben und in Form von rohren, die sich unter dem Finfluss der toßkraft umbördeln. Ziel der Erfindung ist es, eine wirksamere, cinfachere und billigere Stoßdämpfungsausführung zu erreichen, bei der die Dämpfkraft iiber den gesamten Dänpfweg nahezu konstant bleibt. Dies wird erfindungsgemäss dadurch erreicht, dass die StoßkrZft im Stoßdämpfer eine plastische Materialverformung einleitet, die gleich oder ähnlich ist wie die beim Rohr- bzw. Stangenziehen oder beim Valzen. Erfahrungsgemäss ist die Zieh- bzw. Walzkraft beim Kaltwalzen bzv. Ziehen praktisch unabhängig von der Geschwindigkeit.In addition to hydraulic dampers, shock-absorbing members are known in In the form of specially arranged buckling bars and in the form of tubes that are located below bead the fin flow of the toughness. The aim of the invention is to provide a more effective, to achieve simpler and cheaper shock absorption design in which the damping force remains almost constant over the entire Dänpfweg. According to the invention, this is thereby achieved achieves that the shock force in the shock absorber initiates plastic deformation of the material, which is the same or similar to that in tube or rod drawing or in rolling. Experience has shown that the drawing or rolling force in cold rolling or Pulling practically regardless of the speed.

Figur 1 zeigt eine Ausf2hrungsform der Frfindung. Fin Stoßfänger 1, der durch eine Stoßkraft5 10 beaufschlagt wird, wird in einer Diese, die fest mit dem Fohrzeug verbunden ist, in seinem Querschnitt verformt.Figure 1 shows an embodiment of the invention. Fin bumper 1, which is acted upon by an impact force5 10, is in a die, which is fixed with the Fohrzeug is connected, deformed in its cross-section.

Figur 2 zeigt eine weitere Ausführungsform. Ein Stoßfänger 3 wird durch eine Stoßkraft lo zwischen zwei drehbar oder fest im Fahrzeug gelagerte Walzen odrr Kugeln 4 in seinem Cuerschnitt verformt. Sind die Walzen oder Kugeln drehbar gelagert, so leitet die Stoßkraft einen Kaltwelzvorgang, sind sie fest gelagert, einen Kaltziehvorgang ein.Figure 2 shows a further embodiment. A bumper 3 will by an impact force lo between two rotatable or fixed rollers in the vehicle odrr balls 4 deformed in its Cu section. Are the rollers or balls rotatable? stored, so the impact force conducts a cold welder process, are they firmly stored, a cold drawing process.

Fine weitere Ausführungsform zeigt Figur 3. A further embodiment is shown in FIG. 3.

Fin Verformungswerkzeug 8 ist in einem Stoßfänger 7 gelagert. :Fin Joch 6, des fest mit dem Fahrzeug verbunden ist, trat das zu verformende Material, das durch diese Anordnung durch die Stoßkraft auf Zug beansprucht wird. Fin deformation tool 8 is mounted in a bumper 7. : Fin Yoke 6, which is firmly connected to the vehicle, entered the material to be deformed, which is stressed by this arrangement by the impact force on train.

Der Stoßdämpfer kann in beliebiger Ausführungsform einfach oder mehrfach am Fahrzeug befestigt oder ;jeweils mit seinen beiden Haupthestundteilen mit unterschiedlichen Fahrzeugteilen verbunden sein. The shock absorber can be single or multiple in any embodiment attached to the vehicle or; each with its two main dog parts with different Be connected to vehicle parts.
