Description

Die Erfindung betrifft eine Klappenstelleinheit, insbesondere für Brennkraftmaschinen, mit einer auf einer Klappenwelle befestigte Klappe, wobei die Klappenwelle in einem Klappenstutzen drehbar gelagert ist, mit einem mit der Klappenwelle über ein Getriebe gekoppelten, im Klappenstutzen angeordneten Stellmotor zum Verstellen der Klappenwelle, mit einer Sensoreinheit zum Erfassen einer Stellposition der Klappenwelle, mit einem auf den Klappenstutzen zu befestigenden Deckel und mit einem am Deckel angeordneten elektrischen Kupplungselement.The invention relates to a flap setting unit, in particular for internal combustion engines, having a flap mounted on a flap shaft, wherein the flap shaft is rotatably mounted in a flap nozzle, with a valve shaft coupled via a gear, arranged in the valve body actuator for adjusting the flap shaft, with a sensor unit for detecting a parking position of the valve shaft, with a cover to be fastened to the valve neck and with an electrical coupling element arranged on the cover.

Klappenstelleinheiten werden beispielsweise als Klappenventilstelleinheiten in der Abgasrückführleitung, oder als Drosselklappenstelleinheiten in der Ansaugleitung der Brennkraftmaschine eingesetzt. Eine derartige Klappenstelleinheit ist beispielsweise aus der DE-A1-195 25 510 bekannt. Bei dieser Klappenstelleinheit sind der Stellmotor sowie ein den Stellmotor mit der Ktappenwelle und der darauf befestigten Klappe verbindendes Zahnradgetriebe im Drosseistutzen angeordnet. Desweiteren weist das auf der Klappenwelle befindliche Verstellrad Schleiferelemente auf, die mit einem Potentiometer zusammenwirken. Das Potentiometer sowie elektrische Leitungen, ein elektrische Kupplungselement und ein das elektrische Kupplungselement mit dem Motor verbindender Motorsteckkontakt sind am Deckel angeordnet. Die Anordnung der elektrischen Motorkupplung ist konstruktiv aufwendig und darüber hinaus verschmutzungs- und vibrationsanfällig, was zu einer Unterbrechung des elektrischen Kontaktes führen kann.Valve position units are used, for example, as flap valve actuating units in the exhaust gas recirculation line or as throttle position units in the intake line of the internal combustion engine. Such a flap setting unit is known for example from DE-A1-195 25 510. In this flap setting unit of the servomotor and a servo motor with the Ktappenwelle and the flap mounted thereon connecting gear transmission are arranged in Drosseistutzen. Furthermore, the adjusting wheel located on the valve shaft has wiper elements which interact with a potentiometer. The potentiometer and electrical lines, an electrical coupling element and a motor plug-in contact with the motor connecting the motor coupling contact are arranged on the cover. The arrangement of the electric motor coupling is structurally complex and moreover pollution and vibration prone, which can lead to an interruption of the electrical contact.

Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde, eine Klappenstelleinheit zu schaffen, die die oben genannten Nachteile vermeidet.On this basis, the invention is therefore based on the object to provide a flap setting unit which avoids the disadvantages mentioned above.

Diese Aufgabe wird dadurch gelöst, daß ein deckelseitiges Lager für eine Motorwelle des Stellmotors sowie funktionelle Teile des Stellmotors am Deckel derart angeordnet sind, daß der Stellmotor durch Aufsetzen des Deckels auf den Klappenstutzen fertiggestellt ist.This object is achieved in that a cover-side bearing for a motor shaft of the servomotor and functional parts of the servomotor are arranged on the lid such that the servomotor is completed by placing the lid on the valve body.

Die erfindungsgemäße Klappenstelleinheit ist auf besonders einfache und kostengünstige Weise herzustellen. Dadurch, daß das deckelseitige Lager sowie wesentliche funktionelle Teile des Stellmotors am Deckel angeordnet sind, kann die komplette elektrische Motorkupplung entfallen. Der Motor wird durch einfaches Aufsetzen des Deckels zusammengebaut. Ein weiterer Vorteil dieser Anordnung besteht darin, daß die Abgabe der Motorleistung über das Getriebe nun zwischen den beiden Lagerstellen stattfindet, wodurch die Krafteinleitung in die Motorwelle wesentlich günstiger erfolgt.The flap setting unit according to the invention is to produce in a particularly simple and cost-effective manner. The fact that the cover-side bearing and essential functional parts of the servomotor are arranged on the cover, the entire electric motor coupling can be omitted. The engine is assembled by simply placing the lid. Another advantage of this arrangement is that the delivery of engine power via the transmission now takes place between the two bearings, whereby the force is introduced into the motor shaft much cheaper.
