an bekannten Kribbelfilter wie dem der
Zur Lösung dieses Problems ist es bekannt, zusätzlich zu dem so genannten Kribbelfilter eine Dämpferdose als Dämpfungsfilter in dem hydraulischen System anzuordnen. Die Dämpfungseigenschaften eines solchen hydraulischen Systems hängen von verschiedenen Einflussgrößen ab, so von der Auslegung der Dämpferdose, der Auslegung des Kribbelfilters und der Länge der hydraulischen Leitung. Insbesondere sind Eigenfrequenzen dieses Systems durch die verwendeten Baugruppen festgelegt.to Solution to this problem is known in addition to the so-called Kribbelfilter a damper box as To arrange damping filter in the hydraulic system. The damping properties of such a hydraulic Systems depend on different factors so from the design of the damper box, the interpretation the Kribbelfilters and the length of the hydraulic line. In particular, natural frequencies of this system are used by the Modules defined.
Eine Aufgabe der vorliegenden Erfindung ist es daher, ein hydraulisches System anzugeben, dessen Dämpfungseigenschaften, insbesondere Eigenfrequenzen, veränderbar sind.A Object of the present invention is therefore to provide a hydraulic Specify system whose damping properties, in particular Natural frequencies, are changeable.
Dieses Problem wird gelöst durch ein Strömungselement für ein hydraulisches System mit einem Stecker und einer Buchse zur Verbindung mit dem hydraulischen System, dadurch gekennzeichnet, dass eine hydraulische Länge des Strömungselementes zwischen dem Stecker und der Buchse veränderbar ist. Das Strömungselement kann beliebig innerhalb eines hydraulischen Systems angeordnet werden. Vorzugsweise wird es in einer Stichleitung einer Dämpferdose angeordnet. Die hydraulische Länge entspricht einer geometrischen Länge des Strömungselementes oder ist mit einer solchen linear verknüpft. Unter hydraulischer Länge wird somit eine Längenangabe verstanden, die in die Berechnung von Schwingungseigenfrequenzen eines hydraulischen Systems, in dem das Strömungselement angeordnet ist, eingeht.This Problem is solved by a flow element for a hydraulic system with a plug and a Bush for connection to the hydraulic system, characterized that a hydraulic length of the flow element is changeable between the plug and the socket. The Flow element can be arbitrary within a hydraulic Systems are arranged. Preferably, it is in a stub of a damper box arranged. The hydraulic length corresponds to a geometric one Length of the flow element or is with a linked linearly. Under hydraulic length Thus, a length specification is understood that in the calculation of Vibration natural frequencies of a hydraulic system in which the Flow element is arranged, received.
Das Strömungselement umfasst vorzugsweise ein Teleskopelement mit einem Teleskopzylinder und einem Teleskopkolben. Vorzugsweise ist weiter vorgesehen, dass das Strömungselement Mittel zur Festlegung des Teleskopzylinders gegenüber dem Teleskopkolben umfasst. Die Mittel zur Festlegung des Teleskopzylinders gegenüber dem Teleskopkolben bewirken vorzugsweise eine rebschlüssige Festlegung. Alternativ können hier auch Klemm- oder Schraubmittel wie z. B. eine Überwurfmutter oder dergleichen vorgesehen sein. Eine reibschlüssige Verbindung ist dabei allerdings besonders einfach zu handhaben. Vorzugsweise ist zwischen dem Teleskopzylinder und der Teleskopkolben eine Dichtung angeordnet. Die Dichtung bewirkt neben einer Abdichtung gegenüber der Umgebung vorzugsweise gleichzeitig die reibschlüssige Festlegung des Teleskopzylinders gegenüber dem Teleskopkolben. Dadurch können zusätzliche Baugruppen, die diese Funktion übernehmen, eingespart werden. Die Dichtung ist vorzugsweise eine O-Ring Dichtung, die in einer Ringnut des Teleskopkolbens angeordnet ist.The Flow element preferably comprises a telescopic element with a telescopic cylinder and a telescopic piston. Preferably is further provided that the flow element means for fixing the telescopic cylinder relative to the telescopic piston includes. The means for fixing the telescopic cylinder opposite the telescopic piston preferably cause a rebschlüssige Setting. Alternatively, clamping or screwing can also be used here such as B. a union nut or the like provided be. A frictional connection is however especially easy to handle. Preferably, between the telescopic cylinder and the telescopic piston arranged a seal. The seal causes in addition to a seal against the environment preferably simultaneously the frictional fixing of the telescopic cylinder opposite the telescopic piston. This can be additional Assemblies that take over this function can be saved. The seal is preferably an O-ring seal that fits in a Ring groove of the telescopic piston is arranged.
Das eingangs genannte Problem wird auch gelöst durch ein hydraulisches System, insbesondere für Kraftfahrzeuge, umfassend einen Geberzylinder, einen Nehmerzylinder sowie eine diese verbindende Druckleitung, dadurch gekennzeichnet, dass an oder in der Druckleitung ein erfindungsgemäßes Stromungselement angeordnet ist.The The problem mentioned above is also solved by a hydraulic System, in particular for motor vehicles, comprising a Master cylinder, a slave cylinder and a connecting them Pressure line, characterized in that on or in the pressure line arranged an inventive flow element is.
Vorzugsweise umfasst das hydraulische System einen Dämpfungsfilter, wobei das Strömungselement in einer zu dem Dämpfungsfilter führenden Stichleitung angeordnet ist.Preferably the hydraulic system comprises a damping filter, wherein the flow element in a to the damping filter leading stub is arranged.
Das eingangs genannte Problem wird auch gelöst durch die Verwendung eines erfindungsgemäßen Strömungselementes zur Veränderung der hydraulischen Resonanzlänge von zumindest Teilen eines hydraulischen Systems.The The problem mentioned at the outset is also solved by the use a flow element according to the invention for changing the hydraulic resonance length of at least parts of a hydraulic system.
