Abstract
Die Erfindung betrifft eine Kolben-Zylinder-Anordnung, insbesondere für eine Kupplungsbetätigungseinheit eines Fahrzeuges, bestehend aus einem als Gehäuse (1) ausgebildeten, konzentrischen Zylinder, in dem ein Kolben (2) axial beweglich gelagert ist, wobei der Kolben (2) an einem Ausrücklager (4) angreift, welches eine Kupplung betätigt, wobei an einem Innenring (5) des Ausrücklagers (4) ein Targethalterungsmitnahmeelement (7) angeordnet ist, welches eine Sensortargethalterung (12) trägt, wobei das an der Sensortargethalterung (12) befestigte Sensortarget (10) in einer Wirkverbindung zu einem an dem Gehäuse (1) fest positionierten Sensor (13) steht. Bei einer Kolben-Zylinder-Anordnung wird die Genauigkeit der Wegmessung des Kolbens verbessert, wenn das Ausrücklager (4) über das Targethalterungsmitnahmeelement (7) mit dem Kolben (2) verbunden ist, indem das Targethalterungsmitnahmeelement (7) zwischen dem Innenring (5) des Ausrücklagers (4) und einer Stirnseite des Kolbens (2) angeordnet ist.The invention relates to a piston-cylinder arrangement, in particular for a clutch actuation unit of a vehicle, consisting of a housing (1) formed, concentric cylinder in which a piston (2) is mounted axially movable, wherein the piston (2) on a Disengaging bearing (4) which actuates a clutch, wherein on an inner ring (5) of the release bearing (4) a Targethaltermitmitnahmeelement (7) is arranged, which carries a Sensortargethalterung (12), wherein the attached to the Sensortargethalterung (12) sensor target ( 10) in operative connection with a housing (1) fixedly positioned sensor (13). In a piston-cylinder arrangement, the accuracy of displacement measurement of the piston is improved when the release bearing (4) is connected to the piston (2) via the target support driver (7) by sandwiching the target support driver (7) between the inner ring (5) of the Release bearing (4) and an end face of the piston (2) is arranged.
Description
Die Erfindung betrifft eine Kolben-Zylinder-Anordnung, insbesondere für eine Kupplungsbetätigungseinheit eines Fahrzeuges, bestehend aus einem als Gehäuse ausgebildeten konzentrischen Zylinder, in dem ein Kolben axial beweglich gelagert ist. wobei der Kolben an einem Ausrücklager angreift, welches eine Kupplung betätigt, wobei an einem Innenring des Ausrücklagers ein Targethalterungsmitnahmeelement angeordnet ist, welches eine Sensortargethalterung trägt, wobei das an der Sensortargethalterung befestigte Sensortarget in einer Wirkverbindung zu einem an dem Gehäuse fest positionierten Sensor steht.The invention relates to a piston-cylinder arrangement, in particular for a clutch actuation unit of a vehicle, consisting of a housing designed as a concentric cylinder in which a piston is mounted axially movable. wherein the piston engages a release bearing which actuates a clutch, wherein on a inner ring of the release bearing a Targethalterungsmitnahme element is arranged, which carries a sensor target holder, wherein the attached to the sensor target holder sensor target is in operative connection to a fixedly positioned on the housing sensor.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Kolben-Zylinder-Anordnung anzugeben, bei welcher die Genauigkeit der Wegmessung des Kolbens verbessert wird. The invention has for its object to provide a piston-cylinder arrangement in which the accuracy of the displacement measurement of the piston is improved.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, dass das Ausrücklager über das Targethalterungsmitnahmeelement mit dem Kolben verbunden ist, in dem das Targethalterungsmitnahmeelement zwischen dem Innenring des Ausrücklagers und einer Stirnseite des Kolbens angeordnet ist. Dies hat den Vorteil, dass eine hochgenaue Messung des Weges des Kolben dadurch möglich, dass durch die Anbindung des Targethalterungsmitnahmeelementes zwischen Innenring des Ausrücklagers und Stirnseite des Kolbens Taumelbewegungen unterbunden werden, wodurch das Sensorsignal verbessert wird, ohne das zusätzliche Bauelemente notwendig sind. According to the invention the object is achieved in that the release bearing is connected via the Targethalterungsmitnahmeelement with the piston in which the Targethalterungsmitnahmeelement between the inner ring of the release bearing and an end face of the piston is arranged. This has the advantage that a highly accurate measurement of the travel of the piston is possible in that tumbling motions are prevented by the connection of the target holder driving element between the inner ring of the release bearing and the end face of the piston, whereby the sensor signal is improved, without the additional components are necessary.
Vorteilhafterweise ist das Ausrücklager zum Targethalterungsmitnahmeelement radial verschiebbar gelagert.Advantageously, the release bearing is mounted radially displaceable for Targethalterungsmitnahmeelement.
In einer Ausgestaltung ist das Targethalterungsmitnahmeelement zur Stützung einer Vorlastfeder radial am Ausrücklager nach außen geführt. In one embodiment, the Targethalterungsmitnahmeelement is guided to support a preload spring radially on the release bearing to the outside.
In einer Variante greift das nach außen geführte Ende des Targethalterungsmitnahmeelementes in eine schuhförmige Anbindung der Sensortargethalterung ein. Durch diese Verbindung kann mittels des Targets und des Sensors der Ausrückweg des Kolbens bzw. des Ausrücklagers zuverlässig bestimmt werden.In a variant, the outwardly guided end of the Targethalterungsmitnahmeelementes engages in a shoe-shaped connection of the sensor target holder. Through this connection, the release travel of the piston or the release bearing can be reliably determined by means of the target and the sensor.
Die Erfindung lässt zahlreiche Ausführungen zu. Eine davon soll anhand der in der Zeichnung dargestellten Figuren näher erläutert werden. The invention allows numerous versions. One of them will be explained in more detail with reference to the figures shown in the drawing.
