Abstract
Description
Die Erfindung betrifft eine Koppelstange für die Betätigung einer Regelklappe einer Abgasrückführung einer Brennkraftmaschine, wobei die Koppelstange mit einer ersten Seite mit einer Betätigungseinrichtung und einer zweiten Seite mit einer Abgasregelklappe über Anlenkpunkte verbunden ist.The The invention relates to a coupling rod for the actuation of a control flap Exhaust gas recirculation of a Internal combustion engine, wherein the coupling rod with a first side with an actuating device and a second side with an exhaust control flap via articulation points connected is.
Eine
derartige Koppelstange ist aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Koppelstange für die Koppelung einer Betätigungseinrichtung mit einer Abgasregelklappe zu schaffen, wobei die Koppelstange Anbautoleranzen sowie mögliche Achsversätze und Schrägstellungen ausgleichen soll.Of the Invention is based on the object, a coupling rod for the coupling an actuating device to provide with an exhaust control flap, the coupling rod cultivation tolerances and possible axis offsets and compensate for inclinations should.
Diese Aufgabe wird dadurch gelöst, dass die Koppelstange auf der Seite der als elektrischer Steller ausgeführten Betätigungseinrichtung ein Elastomerlager und auf der Seite der Abgasregelklappe ein Gelenklager aufweist. Durch das Elastomerlager werden mögliche Achsversätze und Schrägstellungen der Anlenkhebel ausgeglichen, sowie Schwingungen der Koppelstange um ihre Längsachse gedämpft. Das Gelenklager lässt durch die Verstellung hervorgerufene Drehbewegungen zu und gleicht Anbautoleranzen aus.These Task is solved by that the coupling rod on the side of as an electric actuator executed actuator an elastomeric bearing and on the side of the exhaust control flap, a spherical plain bearing having. Due to the elastomer bearing possible axial offsets and inclinations balanced the lever, and vibrations of the coupling rod around its longitudinal axis attenuated. The joint bearing leaves caused by the adjustment rotational movements and equalizes Cultivation tolerances.
In weiterer Ausgestaltung der Erfindung ist das Gelenklager als temperaturbeständiges Lager ausgeführt. Da sich der Anlenkpunkt der Abgasregelklappe in der Nähe einer heißen Abgasleitung befindet, ist die Verwendung eines wärmeresistenten Lagers bezüglich der Lebensdauer der Lagerstelle von Vorteil.In Another embodiment of the invention, the joint bearing is designed as a temperature-resistant bearing. There the point of articulation of the exhaust control flap near a be called Exhaust pipe is located, the use of a heat resistant Bearing re the life of the bearing advantageous.
In Weiterbildung der Erfindung ist das Gelenklager als Kugelgelenklager ausgebildet und aus einer Molybdänlegierung gefertigt. Durch das Kugelgelenk werden eine reibungsarme Drehbewegung ermöglicht und zugleich Anbautoleranzen problemlos ausgeglichen. Durch die Molybdänlegierung wird eine hohe Härte und Temperaturbeständigkeit des Gelenklagers garantiert.In Further development of the invention is the spherical plain bearings as ball and socket bearings formed and made of a molybdenum alloy manufactured. The ball joint is a low-friction rotary motion allows and at the same time easily compensates cultivation tolerances. By the molybdenum alloy becomes a high hardness and temperature resistance of the hinge bearing guaranteed.
In weiterer Ausgestaltung der Erfindung sind das Gelenk- und das Elastomerlager mit der Koppelstange verpresst. Hierdurch wird eine sichere Verbindung zwischen den Lagern und der Koppelstange gewährleistet.In Another embodiment of the invention are the joint and the elastomeric bearings pressed with the coupling rod. This will be a secure connection ensured between the bearings and the coupling rod.
In Weiterbildung der Erfindung sind die Durchmesser des Gelenk- und des Elastomerlagers unterschiedlich ausgebildet. Dadurch wird eine korrekte Zuordnung des jeweiligen Lagers zu dem richtigen Anlenkpunkt sichergestellt und somit eine Falschmontage verhindert.In Development of the invention, the diameter of the joint and the elastomer bearing are different educated. This will make a correct assignment of each Warehouse to the right pivot point ensured and thus a wrong assembly prevented.
In weiterer Ausgestaltung der Erfindung liegt der Schwerpunkt der Koppelstange auf der direkten Verbindungslinie der Anlenkpunkte.In Another embodiment of the invention is the focus of the coupling rod on the direct connecting line of the articulation points.
Somit treten keine zusätzlichen dynamischen Kräfte auf und die Belastung der Lagerstellen kann niedriger gehalten werden.Consequently There are no additional ones dynamic forces on and the load on the bearings can be kept lower.
In Weiterbildung der Erfindung ist die Koppelstange aus Aluminium gefertigt. Hierdurch wird die Masse der Koppelstange reduziert, wodurch sich die durch die Motoranregung erzeugten Lagerkräfte verringern und somit die Lebensdauer erhöht wird.In Further development of the invention, the coupling rod is made of aluminum. As a result, the mass of the coupling rod is reduced, causing the reduce bearing forces generated by the motor excitation and thus the Lifespan increased becomes.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind der Zeichnungsbeschreibung zu entnehmen, in der ein in den Figuren dargestelltes Ausführungsbeispiel der Erfindung näher beschrieben ist.Further advantageous embodiments of the invention are the drawing description to take in the illustrated in the figures embodiment closer to the invention is described.
