Description
Die Erfindung betrifft eine elektrische Drehstellvorrichtung für ein Stellorgan in einem Kraftfahrzeug mit einem Gehäuse, in dem ein Stellmotor und eine Getriebeeinrichtung vorgesehen sind, wobei die Getriebeeinrichtung eine Ausgangswelle aufweist, die mit dem Stellorgan gekoppelt ist, wobei eine Fail-Safe-Einrichtung vorgesehen ist, die eine Rückstellfeder aufweist, wobei die Rückstellfeder durch den Stellmotor in einer Endlagenposition vorgespannt durch eine elektrisch anzusteuernde Verriegelungseinrichtung fixierbar ist. The invention relates to an electric rotary actuator for an actuator in a motor vehicle having a housing in which a servomotor and a transmission device are provided, wherein the transmission device has an output shaft which is coupled to the actuator, wherein a fail-safe device is provided, which has a return spring, wherein the return spring is biased by the servomotor in an end position biased by an electrically controlled locking device.
In heutigen Kraftfahrzeugen befinden sich eine Vielzahl von derartigen Drehstellvorrichtungen. Sie werden beispielsweise eingesetzt, um Klappenventile zu steuern, die beispielsweise als Drosselklappenventile zur Versorgung einer Brennkraftmaschine mit Ansaugluft oder auch als sogenannte Bypassventile, die den Kühlfluidkreislauf durch einen Kühler oder an diesem vorbeisteuern, eingesetzt werden. Da es sich hierbei um Steuerungseinrichtungen handelt, deren Fehlfunktion einen Ausfall der Brennkraftmaschine verursachen könnten, weisen diese elektrischen Drehstellvorrichtungen eine Fail-Safe-Einrichtung auf, die auch bei Ausfall des Stellmotors und der elektrischen Grundversorgung eine Basisfunktion bereitstellen, mit der eine Werkstatt zur Behebung der Störung aufgesucht werden kann. Eine gattungsgemäße elektrische Drehstellvorrichtung ist beispielsweise aus der
Aufgabe der Erfindung ist es daher, den oben genannten Nachteil auf einfache und kostengünstige Weise zu vermeiden. The object of the invention is therefore to avoid the above-mentioned disadvantage in a simple and cost-effective manner.
Diese Aufgabe wird dadurch gelöst, dass die Verriegelungseinrichtung eine rotatorisch wirkende Magnetkupplung ist. Durch eine derartige rotatorisch wirkende Magnetkupplung ist in jedem Fall eine optimale Bauraumausnutzung gewährleistet. This object is achieved in that the locking device is a rotationally acting magnetic coupling. By such a rotationally acting magnetic coupling an optimal space utilization is guaranteed in each case.
Hierbei ist es besonders vorteilhaft, wenn die Getriebeeinrichtung ein Abtriebszahnrand aufweist, das eine Teilringnut besitzt, in die ein Mitnehmerstift eines Fail-Safe-Rades eingreift und wobei die Rückstellfeder als Drehfeder ausgeführt ist, die mit einem ersten Ende auf das Fail-Safe-Rad angreift und mit einem zweiten Ende auf ein Gehäuseteil des Gehäuses angreift. It is particularly advantageous if the transmission device has a driven tooth edge, which has a Teilringnut, in which engages a driving pin of a fail-safe wheel and wherein the return spring is designed as a torsion spring having a first end to the fail-safe wheel attacks and engages with a second end on a housing part of the housing.
In einer besonders vorteilhaften Ausführungsform weist die Magnetkupplung ein kreisringförmiges Rotororgan auf, das über einen kreisringförmigen Magnetkörper mit einem elektromagnetisch betätigbaren Aktuatororgan zusammenwirkt. Auf diese Weise wird eine besonders kompakte Fail-Safe-Einrichtung für die erfindungsgemäße Drehstellvorrichtung geschaffen, die keinen zusätzlichen Bauraum benötigt. In a particularly advantageous embodiment, the magnetic coupling on an annular rotor member which cooperates via an annular magnetic body with an electromagnetically actuable actuator member. In this way, a particularly compact fail-safe device for the rotary adjusting device according to the invention is provided which requires no additional space.
Die Getriebeeinrichtung kann sowohl als Zahnradgetriebe als auch als Riementrieb ausgeführt sein. The transmission device can be designed both as a gear transmission and as a belt drive.
Die Erfindung wird anhand einer Zeichnung näher erläutert, hierbei zeigt: The invention will be explained in more detail with reference to a drawing, in which:
