Der Erfindung liegt die Aufgabe zu Grunde, eine Zylinder-Kolben-Einheit nach dem Oberbegriff des Patentanspruches 1 anzugeben, die eine wirksamere Steuerung der Viskosität der rheologischen Flüssigkeit ermöglicht.The invention is based on the object Basically, a cylinder-piston unit according to the preamble of the claim 1 specify a more effective control of the viscosity of the rheological fluid allows.
Diese Aufgabe ist durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar.This object is achieved in the claim 1 specified features solved. Advantageous embodiments of the invention can be found in the subclaims.
Die im oder am Kolben angeordneten Spulen können ein elektrisches oder magnetisches Feld bewirken, dass die Viskosität der rheologischen Flüssigkeit insbesondere im Bereich der Verbindungsleitung zumindest in Abhängigkeit eines Parameters verändert. Der Parameter ist von einer Steuerungseinrichtung erfasst, die den elektrischen Stromfluss zu den Spulen und/oder gegebenenfalls die an Elektroden angelegte Spannung bzw. gegebenenfalls den Strom zu einem magnetische Feldlinien bewirkenden Magnetpol steuert. Mit der Anordnung der Spulen am Kolben sind die Abstände zwischen den Spulen und den äußeren Elektroden bzw. Magnetpolen gering, wodurch bereits geringe elektrische Ströme bzw. Spannungen ausreichend sind, um auch größere Viskositätsänderungen der rheologischen Flüssigkeit zu bewirken. Der Parameter kann an den jeweiligen Anwendungsfall angepasst sein und beispielsweise die von der Zylinder-Kolben-Einheit übertragene Kraft, den Weg oder die Geschwindigkeit des Kolbens, die Temperatur der rheologischen Flüssigkeit und/oder die Umgebungstemperatur, die Neigung des mit der Zylinder-Kolben-Einheit ausgestatteten Körpers oder ein von einem Sensor abgegebenes Signal erfas sen, das Körper oder Gegenstände in einem Verstellbereich eines verstellbaren Teiles erkennt, an dem ein Endbereich der Zylinder-Kolben-Einheit angelenkt ist. Über ein mit der Steuerungseinrichtung in Verbindung stehendes Bedienfeld können einzelne Parameter von mehreren möglichen Parametern ausgewählt werden, deren Signale dann von der Steuerungseinrichtung bei der selbsttätigen Regelung des elektrischen Stromes zu den Spulen berücksichtigt werden, damit sich die Viskosität der rheologischen Flüssigkeit und damit das Verhalten der Zylinder-Kolben-Einheit entsprechend ändern.The arranged in or on the piston Can coil an electric or magnetic field cause the viscosity of the rheological liquid especially in the area of the connecting line at least depending of a parameter changed. The parameter is recorded by a control device which controls the electrical current flow to the coils and / or where appropriate voltage applied to electrodes or, if applicable, current controls a magnetic pole causing magnetic field lines. With The arrangement of the coils on the piston are the distances between the coils and the outer electrodes or magnetic poles low, which means that even low electrical currents or Tensions are sufficient to withstand even major changes in viscosity the rheological fluid to effect. The parameter can be adapted to the respective application be adapted and for example the one transmitted by the cylinder-piston unit Force, the path or speed of the piston, the temperature the rheological fluid and / or the ambient temperature, the inclination of the cylinder-piston unit equipped body or detect a signal emitted by a sensor, the body or objects recognizes in an adjustment range of an adjustable part which an end region of the cylinder-piston unit is articulated. About one control panel connected to the control device can individual parameters can be selected from several possible parameters, whose signals are then from the control device in the automatic control of the electrical current to the coils are taken into account so that the viscosity the rheological fluid and thus change the behavior of the cylinder-piston unit accordingly.
Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung mit einer einzigen Figur näher erläutert, die eine Prinzipskizze der Zylinder-Kolben-Einheit darstellt.An embodiment of the invention is explained in more detail with reference to a drawing with a single figure represents a schematic diagram of the cylinder-piston unit.

Die Zylinder-Kolben-Einheit kann an Stelle oder zusätzlich zu den angegebenen Parametern auch andere oder weitere Parameter bei der selbsttätigen Einstellung des elektrischen Stromes zu den Spulen berücksichtigen, wobei in der Steuerungseinrichtung ein entsprechendes Steuerungsprogramm abgespeichert sein kann. Der Kolben der Zylinder-Kolben-Einheit kann axial verstellbar oder um eine Achse schwenkbar im Zylinder angeordnet sein. Die Verbindungsleitung zwischen den Arbeitskammern kann durch wenigstens eine offene oder gegen eine Federkraft an einem Ventilkörper zu öffnende Übertrittsleitung im Zylinder bzw. Kolben oder außerhalb des Zylinders gebildet sein. An Stelle der Kraftmessdose kann eine andere Krafterfassungseinrichtung mit beispielsweise Dehnungsmessstreifen verwendet sein, die geeignet ist, die über die Zylinder-Kolben-Einrichtung übertragene Dreh oder Axialkraft zu erfassen. Die Zylinder-Kolben-Einheit eignet sich als Dämpfer oder Feststelleinrichtung, die auch größere Kräfte aufnehmen kann.The cylinder-piston unit can in place or in addition other or additional parameters for the specified parameters at the self-employed Take into account the setting of the electrical current to the coils, a corresponding control program being stored in the control device can be. The piston of the cylinder-piston unit can be adjusted axially or be arranged in the cylinder so as to be pivotable about an axis. The connecting line between the working chambers can by at least one open or overflow line in the cylinder to be opened against a spring force on a valve body or piston or outside of the cylinder. Instead of the load cell, a other force detection device with, for example, strain gauges be used, which is suitable, the transmitted via the cylinder-piston device Detect torsional or axial force. The cylinder-piston unit is suitable as a damper or locking device that can also absorb larger forces.
