Abstract
Description
Die vorliegende Erfindung betrifft eine Betätigungseinrichtung gemäß den Merkmalen des Patentanspruches 1.The The present invention relates to an actuator according to the features of claim 1.
Aufgabe der Erfindung ist es, eine elektrisch steuerbare Kupplungsbetätigungseinrichtung zu schaffen, die einen einfachen konstruktiven Aufbau und geringe mechanische Verluste aufweist.task The invention is an electrically controllable clutch actuator to create a simple structural design and low has mechanical losses.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Eine Kupplungsbetätigungseinrichtung gemäß der Erfindung weist einen Elektromotor mit einen Anker und einen mit dem Anker gekoppelten Spindelmechanismus auf, der dazu vorgesehen ist, eine vom Elektromotor erzeugte Rotations- bzw. Drehbewegung in eine Verschiebebewegung eines Druckstücks umzusetzen. Ferner ist ein rampenförmiges Element vorgesehen, das über ein Axiallager mit dem Druckstück verbunden ist. Das Axiallager ist dazu vorgesehen, in Axialrichtung der Kupplungsbetätigungseinrichtung wirkende Kräfte von dem rampenförmigen Element aus das Druckstück bzw. umgekehrt zu übertragen und das Druckstück rotatorisch von dem rampenförmigen Element, das drehbar angeordnet sein kann, zu entkoppeln.A Clutch actuator according to the invention has an electric motor with an armature and one with the armature coupled spindle mechanism, which is intended to a generated by the electric motor rotation or rotational movement in a sliding movement a pressure piece implement. Furthermore, a ramp-shaped element is provided, the above a thrust bearing with the pressure piece connected is. The thrust bearing is provided in the axial direction the clutch actuator acting forces from the ramp-shaped Element from the pressure piece or vice versa and the pressure piece rotatory of the ramp-shaped Element that can be rotatably arranged to decouple.
Für die Übertragung einer Kupplungsbetätigungskraft ist ein so genannter Kniehebelmechanismus vorgesehen. Der Kniehebelmechanismus ist vorzugsweise symmetrisch bezüglich einer Drehachse der Kupplung bzw. der Kupplungsbetätigungseinrichtung aufgebaut. Der Kniehebelmechanismus weist mindestens einen ersten Hebel und einen damit über ein Gelenk verbundenen zweiten Hebel auf. Im Bereich des Gelenkes stützt sich der Kniehebelmechanismus an einer Rampe des rampenförmigen Elements ab. Mit dem Kniehebelmechanismus verbunden ist ein Druckelement, das in einer Axialrichtung der Kupplungsbetätigungseinrichtung verschieblich angeordnet ist und das zur Übertragung einer Betätigungskraft auf eine Kupplung vorgesehen ist. Der Kniehebelmechanismus drückt mit dem zweiten Hebel gegen das Druckelement.For the transmission a clutch actuation force is a so-called toggle mechanism provided. The toggle mechanism is preferably symmetrical with respect to a rotation axis of the clutch or the clutch actuator built up. The toggle mechanism has at least a first one Lever and over it a hinged second lever on. In the area of the joint supports the toggle mechanism on a ramp of the ramp-shaped element from. Connected to the toggle mechanism is a pressure element, displaceable in an axial direction of the clutch actuator is arranged and that for transmission an actuating force is provided on a clutch. The toggle mechanism presses with the second lever against the pressure element.
Wie bereits erwähnt, ist der Kniehebelmechanismus vorzugsweise symmetrisch bezüglich einer Drehachse der Kupplungsbetätigungseinrichtung aufgebaut. In diesem Fall sind dann mindestens zwei erste Hebel und mindestens zwei zweite Hebel vorgesehen.As already mentioned, the toggle mechanism is preferably symmetrical with respect to one Built axis of rotation of the clutch actuator. In this case, then at least two first lever and at least provided two second lever.
Nach einer Weiterbildung der Erfindung ist der Kniehebelmechanismus mit dem rampenförmigen Element „mitdrehend” angeordnet.To a development of the invention is the toggle mechanism with the ramp-shaped Element "co-rotating" arranged.
