Description
Die Erfindung betrifft ein Verfahren zum Testen einer Selbstöffnung eines, eine Kupplung betätigenden Hebelaktors, bei welchem mittels einer Rolleneinheit des Hebelaktors zur Einstellung eines Hebelverhältnisses zwischen einem Druckfederpaket am Hebelaktor und einer Hebelfeder der Kupplung ein Rollenweg zurückgelegt wird und bei Erreichen eines maximalen Rollenweges die Rolleneinheit von der Kupplung zurück in eine Ausgangslage gedrückt wird. The invention relates to a method for testing a self-opening of a lever actuator actuating a clutch, in which a roller path is traveled by means of a roller unit of the lever actuator for setting a lever ratio between a compression spring assembly on the lever actuator and a lever spring of the clutch and upon reaching a maximum roller path, the roller unit of the clutch is pressed back into a starting position.
In automatisierten Schaltgetrieben werden Kupplungen verwendet, die im Notfall selbstständig aufgehen müssen. Solche Kupplungen können als Doppelkupplung oder als Einfachkupplung ausgebildet sein und als Kupplungsaktor einen Hebelaktor umfassen. In automated manual transmissions couplings are used, which must be independent in an emergency. Such clutches may be formed as a double clutch or as a single clutch and comprise a lever actuator as a clutch actuator.
Aus der
Der Hebelaktor hat die Eigenschaft, dass er selbstöffnend ist (normally opened), d.h. bei einem Verlust der Netzspannung wird der Hebelaktor durch die Aufstellkraft der Hebelfeder der Kupplung in seine Endlage gebracht. Dadurch wird die Kupplung geöffnet. Um zu verifizieren, ob die Hebelfeder der Kupplung diese Kraft auch im Notfall aufbringen kann, wird vorzugsweise bei jedem „Zündung-AUS“-Zustand des Fahrzeuges ein sogenannter Selbstöffnen-Test durchgeführt. Dieser Test kann jedoch auch bei „Zündung – EIN“ oder anderen Fahrzuständen durchgeführt werden. Dabei fährt der Hebelaktor bis zum maximalen Rollenweg und lässt sich von der Kupplung wieder in seine Endlage bringen. Wenn der Elektromotor ausgeschaltet wird und der Hebelaktor den maximalen Rollenweg einnimmt, ist immer noch unklar, wie stark der Anpressdruck der Reibungskupplung ist. Durch diesen Test wird aber der zulässige Arbeitsbereich sA des Hebelaktors stark eingeschränkt, wie aus
Der Erfindung liegt somit die Aufgabe zugrunde, bei einem Selbstöffnen-Test eines Hebelaktors den zulässigen Arbeitsbereich zu vergrößern, um mehr Verschleißreserve für die Kupplung ohne Verschleißnachstellung zu realisieren.The invention is therefore based on the object in a self-opening test of a lever actuator to increase the allowable work area to realize more wear reserve for the clutch without wear adjustment.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, dass der maximale Rollenweg in Abhängigkeit eines Tastpunktes der Kupplung eingestellt wird. Der Tastpunkt stellt dabei den Weg des Hebelaktors dar, bei welchem die Kupplung beginnt ein Moment zu übertragen. Ein solcher Selbstöffnen-Test kann bei der Kupplung insbesondere deshalb in Abhängigkeit vom Tastpunkt ausgeführt werden, weil die Kupplung zu diesem Weg ein kleineres Moment besitzt, als im Neuzustand oder bei mittlerem Verschleiß der Kupplung, wo der volle Rollenweg gefordert wird, um das Motormoment zu übertragen. Dadurch kann der Arbeitsbereich des Hebelaktors deutlich vergrößert werden, ohne dass an den Bauteilen des Hebelaktors etwas verändert werden muss. Der Einfluss der maximalen Spindelkraft auf den Rollenweg wird dadurch beschränkt.According to the invention, the object is achieved in that the maximum roller travel is set as a function of a touch point of the coupling. The touch point represents the path of the lever actuator, in which the clutch begins to transmit a moment. Such a self-opening test can be carried out in the coupling, in particular, depending on the touch point, because the coupling to this way has a smaller moment than when new or with average wear of the clutch, where the full roller travel is required to the engine torque transfer. As a result, the working range of the lever actuator can be significantly increased without having to change anything on the components of the lever actuator. The influence of the maximum spindle force on the roller path is thereby limited.
Vorteilhafterweise wird der maximale Rollenweg in Abhängigkeit des Tastpunktes beschränkt. Dies erfolgt dadurch, dass ein größerer Arbeitsbereich bei einem kleineren Rollenweg erreicht wird. Darüber hinaus besteht der Vorteil, dass bei minimalem Rollenweg ein geringeres Motormoment vom Elektromotor auf die Rolleneinheit übertragen wird, was zusätzlich energieeinsparend ist.Advantageously, the maximum roller travel is limited as a function of the touch point. This is done by achieving a larger work area with a smaller roller path. In addition, there is the advantage that with minimal roller path, a lower engine torque is transmitted from the electric motor to the reel unit, which is also energy-saving.
In einer Ausgestaltung wird der maximale Rollenweg direkt proportional zum Tastpunkt gewählt. Das hat den Vorteil, dass mit der Größe des Tastpunktes sich der Rollenweg ändert, wobei bei kleinerem Tastpunkt sich der Rollenweg verkleinert, während bei größerem Tastpunkt sich dieser vergrößert. In one embodiment, the maximum roller travel is selected directly proportional to the touch point. This has the advantage that with the size of the touch point, the roller path changes, with a smaller touch point, the roller path decreases, while at a larger touch point, this increases.
In einer Variante wird eine Verschleißänderung des Tastpunktes bei der Bestimmung des maximalen Rollenweges berücksichtigt. Da aufgrund des Verschleißes des Tastpunktes bei größeren Rollenwegen ein geringeres Kupplungsmoment wirkt, kann somit dem Einfluss der maximalen Spindelkraft entgegengewirkt werden, so dass der Hebelaktor vor Beschädigung geschützt wird. In one variant, a change in the wear of the touch point is taken into account when determining the maximum roller travel. Since due to the wear of the touch point with larger roller paths a smaller clutch torque acts, thus the influence of the maximum spindle force can be counteracted, so that the lever actuator is protected from damage.
Vorteilhafterweise wird ein automatisches Selbstöffnen der Kupplung in einer Notfallsituation durch Abschaltung einer Betriebsspannung an einem, die Rolleneinheit antreibenden Elektromotor ausgelöst. Dadurch wird in solchen Notfallsituationen eine Zerstörung der Kupplung unterbunden. Advantageously, an automatic self-opening of the clutch is triggered in an emergency situation by switching off an operating voltage to one, the roller unit driving electric motor. As a result, destruction of the clutch is prevented in such emergency situations.
