Abstract
Description
Die Erfindung betrifft eine Einrichtung zur amplitudenabhängigen Dämpfung von Stößen, insbesondere bei Stoßdämpfern für Kraftfahrzeuge nach dem kennzeichnenden Teil des Anspruchs 1.The The invention relates to a device for amplitude-dependent attenuation of Bumps, especially for shock absorbers for motor vehicles the characterizing part of claim 1.
Insbesondere bei Stoßdämpfern für Kraftfahrzeuge ist es gewünscht, dass hochfrequente Schwingungen mit geringer Amplitude nicht vom eigentlichen Dämpfungsmechanismus des Stoßdämpfers abgefangen werden. Derartige hochfrequente Schwingungen können ausgelöst werden durch das Profil des rollenden Reifens oder geringe Unwuchten des Rades. Sofern diese hochfrequenten Schwingungen mit niedriger Amplitude dem eigentlichen Dämpfungsmechanismus zugeführt werden, kommt es zu Losbrecheffekten, hervorgerufen durch den Stick-Slip-Effekt des Dämpfungskolbens am Dämpfungsgehäuse, was zu einer für den Fahrzeuginsassen spürbaren Unruhe der Radaufhängung führt.In particular for shock absorbers for motor vehicles is it desired that high-frequency vibrations with low amplitude are not from actual damping mechanism intercepted the shock absorber become. Such high-frequency vibrations can be triggered by the profile of the rolling tire or slight imbalance of the wheel. If so high-frequency vibrations with low amplitude the actual damping mechanism supplied breakaway effects, caused by the stick-slip effect of the damping piston on the damper housing what to one for noticeable to the vehicle occupant Unrest of the wheel suspension leads.
Es gibt mehrere Lösungsvorschläge, um dieses Problem zu lösen.It gives several solutions to this Solve a problem.
Nach
der
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur amplitudenabhängigen Dämpfung von Stößen zu finden, die einfacher aufgebaut ist und keine zusätzliche hydraulische Verbindung zwischen den Arbeitsräumen benötigt.The The invention has for its object a device for amplitude-dependent damping To find bumps which is simpler and has no additional hydraulic connection between the workrooms needed.
Die Erfindung wird mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen sind in den Ansprüchen 2 bis 7 beschrieben.The Invention is solved with the features of claim 1. advantageous Training and further education are described in claims 2 to 7.
Der mit der Erfindung erzielte Vorteil liegt insbesondere in dem vereinfachten Aufbau der erfindungsgemäßen Einrichtung. Weiterhin vorteilhaft verringert sich der Einbauraum im Dämpfungsgehäuse. Darüber hinaus vorteilhaft lassen sich in einfacher Weise verschiedene Bauelemente bei unterschiedlicher Anforderung an die Dämpfungscharakteristik miteinander kombinieren.The The advantage achieved with the invention is, in particular, the simplified one Structure of the device according to the invention. The installation space in the damping housing is also advantageously reduced. Furthermore Different components can advantageously be used in a simple manner with different requirements for the damping characteristics with each other combine.
