Abstract
Die Erfindung bezieht sich auf eine Reibungskupplung mit einer Kupplungsbetätigungseinrichtung, welche einen fluidbetätigten Nehmerzylinder aufweist, bei welchem ein Wegsensor integriert ist. Der Wegsensor besteht aus zwei parallel zueinander verlaufenden, isolierten Kontaktstiften, welche von bereits im Betätigungssystem vorhandenen Bauteilen, die elektrisch leitend ausgebildet sind, betätigt werden.The invention relates to a friction clutch with a clutch actuation device which has a fluid-operated slave cylinder in which a displacement sensor is integrated. The displacement sensor consists of two insulated contact pins that run parallel to one another and are actuated by components that are already electrically conductive in the actuation system.
Description
Die Erfindung bezieht sich auf eine Reibungskupplung mit Wegsensor entsprechend dem Oberbegriff des Hauptanspruches.The invention relates to a Friction clutch with displacement sensor according to the preamble of Main claim.
Aus der
Dieser Stand der Technik zeigt einen sehr aufwändigen Endschalter, der sowohl hinsichtlich des Herstellungsaufwandes, des Montageaufwandes als auch hinsichtlich des Volumens sehr aufwändig ist.This prior art shows one very elaborate Limit switch, which both in terms of manufacturing costs, the assembly effort as well as the volume is very complex.
Es ist Aufgabe der vorliegenden Erfindung, einen mechanisch-elektrischen Endschalter für eine Kupplungsbetätigungseinrichtung zu erstellen, welcher mit geringem Aufwand herstellbar ist und der einen geringen Raumbedarf vor allem in axialer Richtung aufweist. Erfindungsgemäß wird diese Aufgabe durch den Hauptanspruch gelöst. Es wird vorgeschlagen, dass der Endschalter aus zwei parallel zueinander verlaufenden, isoliert angeordneten Kontaktstiften besteht, die in Bewegungsrichtung des verschiebbaren Teiles verlaufen und von der elektrisch leitenden Oberfläche dieses Teils leitend miteinander verbindbar sind, wobei dieses Teil bauartbedingt bereits Teil des Ausrücksystems ist.It is an object of the present invention mechanical-electrical limit switch for a clutch actuation device to create which can be produced with little effort and the has a small space requirement, especially in the axial direction. According to the invention Task solved by the main claim. It is suggested, that the limit switch consists of two parallel Insulated contact pins exist in the direction of movement of the movable part and run from the electrically conductive surface this part can be conductively connected to one another, this part is already part of the release system due to its design.
Durch die Verwendung eines bauartbedingt bereits vorhandenen Bauteiles zur leitenden Verbindung der beiden parallel zueinander verlaufenden Kontaktstifte ist es möglich, mit geringem Bauaufwand eine Wegmessung der Kupplungsbetätigungseinrichtung vorzunehmen, wobei die beiden Kontaktstifte außerhalb des Kupplungssystems mit einem Auswertegerät verbunden werden können. Es ist so mit geringem technischen Aufwand möglich, z. B. den Verschleißzustand der Kupplungsscheibe rechtzeitig feststellen zu können.By using a design already existing component for the conductive connection of the two in parallel mutually extending contact pins, it is possible with little construction a distance measurement of the clutch actuation device the two contact pins outside the coupling system with an evaluation device can be connected. It is possible with little technical effort, for. B. the state of wear to be able to determine the clutch disc in good time.
Es wird weiter vorgeschlagen, dass der kupplungsnahe Nehmerzylinder als separates Bauteil ausgeführt ist mit einem zylindrischen Gehäuse und einem darin verschiebbaren Kolben mit elektrisch leitender Oberfläche, wobei in der dem Kolben gegenüberliegenden Wandung des Gehäuses, welche den Druckraum abschließt, die beiden Kontaktstifte angeordnet sind, die in Richtung auf den Kolben zu verlaufen und durch diesen direkt leitend miteinander verbindbar sind. Durch diese Anordnung sind die beiden Kontaktstifte vor Beschädigungen geschützt im Nehmerzylinder angeordnet und werden direkt vom Kolben betätigt, wobei der Kolben entweder eine elektrisch leitende Oberfläche aufweisen oder aus einem elektrisch leitenden Material bestehen muss.It is further suggested that the slave cylinder close to the clutch is designed as a separate component with a cylindrical housing and a piston displaceable therein with an electrically conductive surface, wherein in the opposite of the piston Wall of the housing, which closes the pressure room, the two contact pins are arranged in the direction of the Piston to run and through this directly conductive with each other are connectable. With this arrangement, the two contact pins from damage protected in Slave cylinders are arranged and are operated directly by the piston, whereby the piston either have an electrically conductive surface or must consist of an electrically conductive material.
Ein weiteres Merkmal der Erfindung ist darin zu sehen, dass der kupplungsnahe Nehmerzylinder konzentrisch um die Getriebewelle (Drehachse) angeordnet ist, einen in einem Ringraum verschiebbaren Ringkolben aufweist, der auf der dem Druckraum abgewandten Seite ein Ausrücklager trägt und am Gehäuse des Nehmerzylinders die Kontaktstifte vorgesehen sind, die parallel zur Drehachse verlau fen und die durch elektrisch leitende Teile des Ausrücklagers bzw. dessen Halterung direkt leitend miteinander verbindbar sind. Somit ist in einfacher Weise mit geringem technischen Aufwand und sehr raumsparend auch ein konzentrisch zur Drehachse angeordnetes Ausrücksystern ausrüstbar.Another feature of the invention can be seen in the fact that the slave cylinder close to the clutch is concentric is arranged around the gear shaft (axis of rotation), one in one Annular space displaceable annular piston which on the side facing away from the pressure space Side a release bearing carries and on the housing of the slave cylinder, the contact pins are provided in parallel to the axis of rotation and through electrically conductive parts of the release bearing or its holder can be directly connected to each other. It is thus easy and with little technical effort very space-saving also one arranged concentrically to the axis of rotation Ausrücksystern be equipped.
Die Erfindung wird anschließend anhand von Ausführungsbeispielen näher erläutert. Es zeigen im Einzelnen:The invention is then based on of embodiments explained in more detail. It show in detail:
