Description
Die Erfindung betrifft ein Ein-/Ausrücksystem für eine aus zwei Teilkupplungen bestehende Doppelkupplung mit einer Wegmesseinrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an input / release system for a dual clutch consisting of two partial clutches with a displacement measuring device having the features of the preamble of
Zur Wegbestimmung oder Positionserfassung von Kolben von Kupplungsausrücksystemen kommen viele technische Lösungen zum Einsatz, die Magnete in Zusammenwirkung mit einem Sensor verwenden. Üblicherweise wird der Magnet an dem Kolben befestigt, der die bewegliche Komponente des fluidischen oder pneumatischen Zylinders darstellt, während der Sensor an dem im Bezug zum Kolben feststehenden Zylindergehäuse angeordnet ist.To determine the position or position of pistons from clutch release systems many technical solutions are used, the magnets use in conjunction with a sensor. Usually, the magnet is fastened to the piston, which constitutes the movable component of the fluidic or pneumatic cylinder, while the sensor is arranged on the cylinder housing fixed relative to the piston.

Neben diesem Stand der Technik, der auf dem Prinzip des Hall-Effekts aufgebaut ist, sind weitere Lösungen mit Sensoren bekannt, die ein veränderliches Magnetfeld auswerten.In addition to this state of the art, which is based on the principle of the Hall effect, other solutions with sensors are known that evaluate a variable magnetic field.
Dazu gehört auch der Einsatz von linear variablen Differential-Transformatoren (LVDT) bei der Wegmessung, deren Arbeitsweise auf der örtlichen Sättigung eines Spulenkreises basiert. Derartige Einrichtungen mit Verwendung eines LVDT sind beispielsweise in
Der Nachteil dieser technischen Lösungen, die eine Wegmessung oder Positionsbestimmung mittels Magneten durchführen, besteht darin, dass eine Veränderung der Lage des Magneten, zum Beispiel durch leichtes Verkippen oder Verdrehen des Kolbens, zu einer veränderten Magnetfeldkonstellation am Ort des Sensors und damit zu einer Fehlinterpretation der Lagemessung führt. Zudem können metallische Bauteile, die sich in der Umgebung der Messanordnung befinden, ebenfalls die Messung beeinflussen.The disadvantage of these technical solutions, which perform a displacement measurement or position determination by means of magnets, is that a change in the position of the magnet, for example, by slight tilting or twisting of the piston, to a changed magnetic field constellation at the location of the sensor and thus to a misinterpretation of Position measurement leads. In addition, metallic components located in the vicinity of the measuring arrangement can also influence the measurement.
Es sind des Weiteren technische Lösungen bekannt, die als Messmethode eine Wegmessung nach dem Wirbelstromprinzip vornehmen. Bekanntermaßen wird bei nach dem Wirbelstrommessverfahren arbeitenden Wegmesssystemen die Änderung der Impedanz einer in einem Sensor angeordneten Messspule bei Änderung/Entfernung eines elektrisch und/oder magnetisch leitfähigen Messobjektes gemessen.Furthermore, technical solutions are known which make a displacement measurement according to the eddy current principle as a measuring method. As is known, in displacement measuring systems operating according to the eddy current measuring method, the change in the impedance of a measuring coil arranged in a sensor is measured when changing / removing an electrically and / or magnetically conductive measuring object.
Es sind Wirbelstromlangwegsensoren bekannt, die im Wesentlichen aus einer in einem länglichen Spulenstab angeordneten Messspule mit einer in einem Sensorgehäuse integrierten Elektronik bestehen. Als Messobjekt dient ein metallisches, vorzugsweise nicht ferromagnetisches Rohr, welches konzentrisch über dem Spulenstab in dessen Längsrichtung bewegt wird. In Abhängigkeit von der Position des Rohres auf den Spulenstab wird die flächenmäßige Abdeckung des Erregerfeldes variiert. Dadurch lässt sich über induzierte Wirbelströme eine positionsproportionale Erregerfeldschwächung erzielen, die elektromagnetisch ausgewertet werden kann. Üblicherweise werden Wirbelstromlangwegsensoren derart in Hydraulik- oder Pneumatikzylindern eingebaut, dass der Spulenstab vom Abschlussdeckel des Zylinders aus axial in das Zylinderinnere ragt. Das als Messobjekt dienende metallische Rohr ist dabei axial innerhalb des Kolbens und der Kolbenstange angeordnet und schiebt sich entsprechend der Position des Kolbens über den Spulenstab.There are eddy current long-distance sensors are known, which consist essentially of a arranged in an elongated coil rod measuring coil with an integrated electronics in a sensor housing. As a measuring object is a metallic, preferably non-ferromagnetic tube, which is moved concentrically over the coil rod in the longitudinal direction. Depending on the position of the tube on the coil rod, the area coverage of the exciter field is varied. As a result, it is possible to achieve a position-proportional excitation field weakening via induced eddy currents, which can be evaluated electromagnetically. Usually eddy current long-distance sensors are installed in hydraulic or pneumatic cylinders in such a way that the spool rod projects axially from the end cap of the cylinder into the cylinder interior. The serving as the measurement object metallic tube is axially disposed within the piston and the piston rod and pushes according to the position of the piston on the coil rod.
Derartige Anordnungen stellen hohe Ansprüche an die Abdichtung des Sensors und die Kabeldurchführungen aus dem Druckraum des Zylinders heraus. Für den Einsatz bei konzentrisch zu einer Getriebeeingangswelle angeordneten Nehmerzylindern (CSC), deren Kolben ringförmig ausgebildet und konzentrisch zur Achse der Getriebeeingangswelle auf einer Hülse oder einem Führungsrohr angeordnet sind, sind diese Lösungen ungeeignet. Zudem benötigen viele Messaufnehmer Elektronik in ihrer direkten Umgebung. Aufgrund der insbesondere im Bereich des Ein-Ausrücksystem vorhandenen, relativ hohen Temperaturbelastungen sind diese Lösungen daher funktional eingeschränkt bzw. nur mit teuren Spezialbauteilen realisierbar.Such arrangements place high demands on the sealing of the sensor and the cable bushings out of the pressure chamber of the cylinder. For use with concentric to a transmission input shaft arranged slave cylinders (CSC), whose piston is annular and arranged concentrically to the axis of the transmission input shaft on a sleeve or a guide tube, these solutions are unsuitable. In addition, many sensors require electronics in their immediate vicinity. Due to the relatively high temperature loads present in particular in the area of the on-release system, these solutions are therefore functionally restricted or can only be realized with expensive special components.
Ein weiterer Nachteil dieser bekannten Lösungen besteht darin, dass aus Bauraumgründen in axialer und radialer Richtung es in den meisten Fällen nicht möglich ist, einen Sensor vorzugsweise für den inneren Kolben zu platzieren. Somit wird das ganze System nicht mehr funktionsfähig.Another disadvantage of these known solutions is that for space reasons in the axial and radial directions, it is not possible in most cases, preferably to place a sensor for the inner piston. Thus, the whole system is no longer functional.
Die Aufgabe der Erfindung besteht deshalb darin, ein Ein-/Ausrücksystem für eine Doppelkupplung mit einer Wegmesseinrichtung zu schaffen, mit dem in einem axial und radial begrenzten Bauraum die Wegmessung des inneren Kolbens realisierbar ist.The object of the invention is therefore to provide an input / Ausrücksystem for a dual clutch with a displacement measuring device, with which in an axially and radially limited space the distance measurement of the inner piston can be realized.
Diese Lösung wird mit einem Ein-/Ausrücksystem für eine Doppelkupplung mit Wegmesseinrichtung mit den Merkmalen des Anspruchs 1 gelöst.This solution is achieved with an input / Ausrücksystem for a dual clutch with path measuring device with the features of
Die Erfindung betrifft ein Ein-/Ausrücksystem für eine aus zwei Teilkupplungen bestehende Doppelkupplung, wobei jeder Teilkupplung ein in einem gemeinsamen Gehäuse angeordneter und geführter ringförmiger Kolben zugeordnet ist. Erfindungsgemäß weist die Mantelfläche mindestens einer der Kolben mindestens eine Aufnahme mit einer in Betätigungsrichtung verlaufender Durchgangsbohrung auf zur Aufnahme eines Seiles oder eines biegsamen Stranges oder ähnlichem, das in einem endseitig an der Aufnahme sich anschließenden abgewinkelten Rohr winklig zur Betätigungsrichtung aus der Mantelfläche des Gehäuse herausgeführt wird.The invention relates to an input / release system for a double clutch consisting of two partial clutches, wherein each partial clutch is assigned a arranged in a common housing and guided annular piston. According to the invention, the lateral surface of at least one of the pistons has at least one receptacle with a through bore extending in the direction of actuation for receiving a cable or a flexible strand or the like, which is led out of the lateral surface of the housing in an angled tube adjoining the receptacle at an angle to the actuation direction ,
Dabei ist es zur Sensierung des Ausrückweges eines Kolbens besonders vorteilhaft, dass das aus der Mantelfläche des Gehäuses herausragende Ende des Seils mit einem außerhalb des Gehäuses angebrachten Sensors in Wirkverbindung steht. Dadurch kann der Weg aus der Kupplungsglocke gemessen werden.It is particularly advantageous for the sensing of the Ausrückweges a piston that the protruding from the lateral surface of the housing end of the rope is in operative connection with a sensor mounted outside of the housing. As a result, the way out of the clutch bell can be measured.
In einer vorteilhaften Ausgestaltung der Erfindung ist Aufnahme lösbar oder aber unlösbar mit dem Gehäuse verbunden.In an advantageous embodiment of the invention recording is releasably or permanently connected to the housing.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert.The invention will be explained in more detail with reference to an embodiment and associated drawings.
