Abstract
Description
Die
Erfindung betrifft ein Feder-/Dämpferelement
mit mehreren mechanischen Feder-/Dämpferteilelementen, die mittels
zwischengeschalteter elektro- und/oder magnetorheologischer Einrichtungen koppelbar
sind. Ein derartiges Bauteil ist aus der
Mit einer solchen Einrichtung kann zwar die mechanische Eigenschaft des Bauteils beeinflußt werden, jedoch ist eine gezielte Beeinflussung der Steifigkeit und/oder der Dämpfung nicht unabhängig voneinander möglich.With Although such a device may be the mechanical property of the component are affected, However, a targeted influence on the stiffness and / or the damping not independent of each other possible.
Der Erfindung liegt daher die Aufgabe zugrunde, ein gattungsgemäßes Feder-/Dämpferelement zu schaffen, bei welchem mit geringem Aufwand eine gezielte Beeinflussung der Federsteifigkeit und/oder Dämpfungseigenschaften unabhängig voneinander möglich ist.Of the Invention is therefore based on the object, a generic spring / damper element to create, in which with little effort a targeted influence the spring stiffness and / or damping properties independently of each other possible is.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mindestens zwei der elektro-/magnetorheologischen Einrichtungen derart ausgeführt sind, daß das elektro-/magnetorheologische Medium unter Wirkung einer Betriebsbelastung auf einer voneinander unterschiedliche Beanspruchungsart belastet bzw. verformt wird.These Task is inventively characterized solved, that at least two of the electro / magnetorheological devices are designed in such a way that this electro- / magnetorheological Medium under the effect of an operating load on one another different stress type is loaded or deformed.
Ein erfindungsgemäßes Feder-/Dämpferelement besteht also aus einer Anzahl von Teilelementen, die unterschiedliche mechanische Eigenschaften besitzen können, zwischen denen sich eine elektrorheologische und/oder magnetorheologische Flüssigkeit befindet.One Inventive spring / damper element consists of a number of sub-elements, the different may possess mechanical properties, between which a electrorheological and / or magnetorheological fluid located.
Elektrorheologische Flüssigkeiten bzw. magnetorheologische Flüssigkeiten sind Flüssigkeiten, bei denen die rheologischen Eigenschaften stufenlos über das elektrische bzw. magnetische Feld steuerbar sind. In der Regel handelt es sich bei elektrorheologischen Flüssigkeiten bzw. magnetorheologischen Flüssigkeiten um Suspensionen, d.h. in einem Trägermedium suspendierte Festpartikel, die über das elektrische bzw. magnetische Feld polarisierbar sind. Je nach Ausführung der elektro-/magnetorheologischen Einrichtung wird die genannte Flüssigkeit unter Belastung verdrängt (Fließmodus), geschert (Schermodus) oder gedrückt (Quetschmodus). Es kann auch eine Kombination der vorgenannten Moden auftreten (Mischmode). Nähere Einzelheiten hierzu können dem Buch „Technischer Einsatz neuer Aktoren", Expert-Verlag, Renningen-Meinsheim, 1995, Kapitel 2.3.1 und Bild 3.1 entnommen werden.electrorheological liquids or magnetorheological fluids are liquids, at which the rheological properties steplessly over the electrical or magnetic Field are controllable. As a rule, they are electrorheological liquids or magnetorheological fluids to suspensions, i. solid particles suspended in a carrier medium, the over the electric or magnetic field can be polarized. Depending on the version of the electro- / magnetorheological device is the said liquid under Stress displaced (Flow mode), sheared (shear mode) or pressed (Squeeze). It can also be a combination of the aforementioned modes occur (mixed mode). details Details can be the book "Technical Use of new actuators ", Expert-Verlag, Renningen-Meinsheim, 1995, chapter 2.3.1 and picture 3.1 are taken.
Es hat sich nun gezeigt, daß bei einer Koppelung der Teilelemente über eine elektrorheologische und/oder magnetorheologische Einrichtung, die im Schermodus beansprucht ist, im wesentlichen eine gemeinsame Beeinflussung des Feder- und Dämpfungsverhaltens erfolgt. Durch eine Koppelung, die zu einer Beanspruchung im Quetschmodus führt, wird im wesentlichen die Steifigkeit des Systems veränderbar sein, während eine Koppelung im Fließmodus sich am stärksten auf das Dämpfungsverhalten auswirkt. Durch die erfindungsgemäße Kombination von mindestens zwei unterschiedlichen Modi, lassen sich in einem nahezu unbegrenzten Frequenzbereich die gewünschten mechanischen Eigenschaften sowohl für die Federsteifigkeit, als auch für das Dämpfungsverhalten exakt auf die gewünschten Bedingungen einstellen.It has now been shown that at a coupling of the sub-elements via an electrorheological and / or magnetorheological device that claims in shear mode is, essentially a common influence on the spring and damping behavior he follows. Through a coupling that leads to a stress in squeezing mode leads, becomes essentially the rigidity of the system be changeable while a Coupling in flow mode the strongest affects the damping behavior. By the inventive combination of at least two different modes, can be in one almost unlimited frequency range the desired mechanical properties as well as the spring stiffness, as well as for the damping behavior exactly to the desired Set conditions.
Die Funktion sowie weitere vorteilhafte Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung von Ausführungsbeispielen anhand der Zeichnungen.The Function and further advantageous features of the invention result from the following description of embodiments with reference to Drawings.

Die dargestellten Feder-/Dämpferteilelemente können prinzipiell auch einlagig gewickelt ausgebildet sein, dann wird als Drahtmaterial ein Hohldraht verwendet. Der Hohlraum im Draht bildet dann entsprechend die Flüssigkeitskammer die mit elektrorheologischer Flüssigkeit und/oder magnetorheologischer Flüssigkeit gefüllt ist.The illustrated spring / damper sub-elements can in principle also be designed single-layer wound, then will used as a wire material, a hollow wire. The cavity in the wire then forms the liquid chamber accordingly those with electrorheological fluid and / or magnetorheological fluid filled is.
Die vorstehend in den Zeichnungen dargestellten Ausführungsformen von Feder-/Dämpferteilelementen können nun durch Parallel- und/oder Reihenschaltung in beliebiger Kombination miteinander gekoppelt werden, so daß für beliebige Anwendungsgebiete die verschiedensten Feder-/Dämpfereigenschaften erzielbar sind.The Embodiments of spring / damper subassemblies shown above in the drawings can now by parallel and / or series connection in any combination be coupled together so that for any application the most different spring / damper properties can be achieved.
ES wird demnach durch die Erfindung ein elektrisches und/oder magnetisch einstellbare Feder-/Dämpferelement realisiert, bei dem Feder-/Dämpferteilelemente gekoppelt und somit die Federkennlinien in Abhängigkeit eines elektrischen Signals variiert werden können. Die Feder-/Dämpferkräfte können beliebig variiert werden und die Einsatzmöglichkeiten derartiger Feder-/Dämpferelemente sind vielfältig (Dämpfer, Tilger, Motorlager, adaptives Transportsystem). Bei der Kopplung derartiger Feder-/Dämpferelemente mit Massen kann die Eigenresonanz des schwingfähigen Systems verändert werden.IT Accordingly, the invention provides an electrical and / or magnetic adjustable spring / damper element realized in the spring / damper sub-elements coupled and thus the spring characteristics in response to an electrical signal can be varied. The spring / damper forces can be arbitrary be varied and the possible uses such spring / damper elements are diverse (Damper, Absorber, engine mount, adaptive transport system). At the coupling such spring / damper elements With masses, the self-resonance of the oscillatory system can be changed.
