Abstract
Description
Die Erfindung betrifft einen Rotationsdämpfer mit richtungsabhängiger Dämpfung gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a rotary damper with directional Damping according to the preamble of the claim 1.
Verwendung finden Rotationsdämpfer unter anderem in Kraftfahrzeugen zur Dämpfung der Bewegung beispielsweise von Haltegriffen, Handschuhfachdeckeln, Aschenbechern, Cupholdern und dgl., insbesondere wenn die Teile in einer Richtung federbetätigt bewegt werden. Außerhalb des Kraftfahrzeugbereichs werden Rotationsdämpfer beispielsweise an Musikgeräten verwendet, beispielsweise zur Dämpfung der Bewegung von Deckeln oder Fächern von Kassetten-, CD- oder DVD-Laufwerken, insbesondere ebenfalls um eine federbetätigte Bewegung zu dämpfen. Die Aufzählung gibt nur eine kleine Auswahl möglicher Verwendungen von Rotationsdämpfern an.use find rotary dampers, inter alia, in motor vehicles for damping the movement, for example of handles, Glove compartment lids, ashtrays, cup holders and the like, in particular when the parts are spring-actuated in one direction. Outside the motor vehicle area are rotary dampers used for example on music devices, for example for Damping the movement of lids or compartments of cassette, CD or DVD drives, in particular also to dampen a spring-actuated movement. The Aufzählung gives only a small selection possible Uses of rotary dampers on.

Patentschrift
Aufgabe der Erfindung ist ein Rotationsdämpfer mit ebenfalls drehrichtungsabhängiger Dämpfung, der einen anderen Aufbau aufweist.task the invention is a rotary damper with also rotational direction-dependent damping, which has a different structure.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Der erfindungsgemäße Rotationsdämpfer weist ein drehbares Dämpferelement auf, das mindestens einen, vorzugsweise mehrere Durchbrüche aufweist, durch die bei einer Drehung des Dämpferelements die Flüssigkeit, in der es sich befindet, durchtreten kann. Des Weiteren weist der erfindungsgemäße Rotationsdämpfer ein Verschlusselement auf, das sich mit dem Dämpferelement mitdreht und das gegenüber dem Dämpferelement so beweglich ist, dass es dessen Durchbruch oder Durchbrüche wahlweise schließt oder offen lässt. Es ist nicht zwingend für die Erfindung, dass die Durchbrüche vollständig geschlossen oder geöffnet werden, auch ein teilweises, also unvollständiges Schließen oder teilweises Öffnen kann genügen. Es geht darum, einen Durchtrittsquerschnitt oder einen Durchströmungswiderstand der Durchbrechung oder Durchbrechungen des Dämpferelements durch die Bewegung des Verschlusselements gegenüber dem Dämpferelement und dadurch die Dämpfung des Rotationsdämpfers zu verändern.These The object is achieved by the features of claim 1. The inventive Rotary damper has a rotatable damper element on, the at least one, preferably a plurality of breakthroughs by, upon rotation of the damper element the fluid in which it is located can pass. Furthermore, the rotary damper according to the invention a closure element that engages with the damper element rotates and that with respect to the damper element so mobile is it's its breakthrough or breakthroughs optionally closes or leaves open. It is not mandatory for the invention that the breakthroughs be completely closed or opened, also a partial, so incomplete closing or partial opening may suffice. It's about, a passage cross section or a flow resistance the opening or openings of the damper element by the movement of the closure element relative to the Damper element and thereby the damping of the rotary damper to change.
Eine Ausgestaltung der Erfindung sieht vor, dass das Verschlusselement gegenüber dem Dämpferelement drehbar ist, vorzugsweise ist der Drehwinkel des Verschlusselements gegenüber dem Dämpferelement begrenzt. Durch die Flüssigkeitsreibung wird das Verschlusselement bei einer Drehung des Dämpferelements gebremst, so dass sich bei einer Umkehrung der Drehrichtung das Dämpferelement um den begrenzten Drehwinkel gegenüber dem Verschlusselement dreht und das Verschlusselement dann mitdreht. Dadurch wird das gewünschte Schließen und Öffnen der Durchbrüche des Dämpferelements selbsttätig durch die Drehung und Drehrichtung des Dämpferelements erreicht.A Embodiment of the invention provides that the closure element is rotatable relative to the damper element, preferably is the angle of rotation of the closure element relative to the Damper element limited. Due to the fluid friction is the closure element upon rotation of the damper element braked, so that in a reversal of the direction of rotation the Damper element to the limited angle of rotation rotates the closure element and then rotates the closure element. This will make the desired closing and opening the openings of the damper element automatically by the rotation and direction of rotation of the damper element reached.
Eine Ausgestaltung der Erfindung sieht Scheiben als Dämpferelement und/oder Verschlusselement vor, die mindestens einen Durchbruch aufweisen. Durch eine Bewegung des Verschlusselements gegenüber dem Dämpferelement, insbesondere eine Relativdrehung, deckt das Verschlusselement den oder die Durchbrüche des Dämpferelements ab oder gibt sie frei, d. h. das Verschlusselement schließt oder öffnet die Durchbrüche des Dämpferelements. Die Ausbildung als Scheibe ist eine einfache und trotzdem effektive Möglichkeit zur Verwirklichung eines Rotationsdämpfers mit richtungsabhängiger Dämpfung. Weiterer Vorteil ist die Möglichkeit eines kleinbauenden, insbesondere in axialer Richtung schmalen Rotationsdämpfers. Die Durchbrüche des Dämpferelements und des Verschlusselements können, müssen aber nicht deckungsgleich sein. Notwendig und ausreichend für die Erfindung ist, dass sich durch eine Bewegung des Verschlusselements gegenüber dem Dämpferelement eine Durchtrittsfläche oder ein Strömungswiderstand durch die Durchbrüche und damit die Dämpfungswirkung des Rotationsdämpfers ändert.A Embodiment of the invention sees discs as a damper element and / or closure element, the at least one breakthrough exhibit. By a movement of the closure element opposite the damper element, in particular a relative rotation covers the closure element or the openings of the damper element or release them, d. H. the closure element closes or opens the openings of the damper element. Training as a disc is a simple yet effective Possibility to realize a rotary damper with directional damping. Another advantage is the possibility of a small-scale, especially in axial Direction narrow rotary damper. The breakthroughs the damper element and the closure element, but do not have to be congruent. Necessary and sufficient for the invention is that by a movement of the closure element opposite the damper element, a passage surface or a flow resistance through the breakthroughs and thus the damping effect of the rotary damper changes.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:The Invention will now be described with reference to a drawing Embodiment explained in more detail. Show it:
