Description
Die Erfindung betrifft eine Drehmomentübertragungseinrichtung, insbesondere ein Zweimassenschwungrad, umfassend ein Primärmasseblech und einen Primärmassedeckel, wobei der Primärmassedeckel Geberzähne umfasst, die sich im Wesentlichen in axialer Richtung über zumindest einen Teil des Primärmasseblechs erstreckenThe invention relates to a torque transmission device, in particular a dual mass flywheel, comprising a primary mass plate and a primary mass cover, the primary mass cover comprising transducer teeth that extend essentially in the axial direction over at least part of the primary mass plate
Bei Verbrennungsmotoren im Antriebsstrang von Kraftfahrzeugen werden Drehmomentübertragungseinrichtungen wie ein Zweimassenschwungrad mit verzahntem Deckel eingesetzt um die Position des oberen Totpunktes (OT) und den Einspritzzeitpunkt zu erfassen. Je nach Position des Sensors werden unterschiedlich lange Geberzähne benötigt. Liegt die Position des Sensors sehr weit nah an der Motorrückwand werden lange Geberzähne am Deckel benötigt. Dabei unterliegen die Geberzähne einer drehzahlbedingten Aufweitung, die durch längere Geberzähne begünstigt wird. Durch die Aufweitung können die Geberzähne plastifizieren, sodass der Sensor nicht mehr in der Lage ist, die korrekte Position des OT zu erfassen und/oder die sich aufweitenden Geberzähne den Sensor sich berühren und zerstören, was zu einem Liegenbleiben des Kraftfahrzeuges führt.In internal combustion engines in the drive train of motor vehicles, torque transmission devices such as a two-mass flywheel with a toothed cover are used to detect the position of top dead center (TDC) and the point in time of injection. Depending on the position of the sensor, encoder teeth of different lengths are required. If the position of the sensor is very close to the rear wall of the motor, long encoder teeth are required on the cover. The encoder teeth are subject to a speed-related expansion that is favored by longer encoder teeth. The widening can plasticize the encoder teeth so that the sensor is no longer able to detect the correct position of the TDC and / or the widening encoder teeth touch the sensor and destroy it, which leads to the motor vehicle stopping.
Eine Aufgabe der Erfindung ist es daher, die zuvor genannten Nachteile zu vermeiden.It is therefore an object of the invention to avoid the disadvantages mentioned above.
Dieses Problem wird durch eine Drehmomentübertragungseinrichtung nach Anspruch 1 gelöst. Bevorzugte Ausführungsformen, Ausgestaltungen oder Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This problem is solved by a torque transmission device according to
Das oben genannte Problem wird insbesondere gelöst durch eine Drehmomentübertragungseinrichtung, insbesondere Zweimassenschwungrad, umfassend ein Primärmasseblech und einen Primärmassedeckel, wobei der Primärmassedeckel Geberzähne umfasst, die sich im Wesentlichen in axialer Richtung über zumindest einen Teil des Primärmasseblechs erstrecken, wobei die dem Primärmasseblech zugewandten Enden der Geberzähne mit dem Primärmasseblech verbunden sind. Die Drehmomentübertragungseinrichtung ist in einer Ausführungsform der Erfindung ein Zweimassenschwungrad mit einer Primärseite und einer Sekundärseite, die entgegen eines Rückstellmomentes, das durch eine zwischen beiden verspannte Bogenfeder erzeugt werden kann, gegeneinander verdrehbar sind. Die Primärseite umfasst dabei ein Primärmasseblech und einen Primärmassedeckel, die miteinander fest verbunden, insbesondere verschweißt sind.The above-mentioned problem is solved in particular by a torque transmission device, in particular a dual-mass flywheel, comprising a primary mass plate and a primary mass cover, the primary mass cover comprising transmitter teeth which extend essentially in the axial direction over at least part of the primary mass plate, the ends of the donor teeth facing the primary mass plate are connected to the primary mass plate. In one embodiment of the invention, the torque transmission device is a dual-mass flywheel with a primary side and a secondary side, which can be rotated against each other against a restoring torque that can be generated by an arc spring tensioned between the two. The primary side comprises a primary mass plate and a primary mass cover, which are firmly connected to one another, in particular welded.
Die Geberzähne gehen in einer Ausführungsform der Erfindung an den dem Primärmassedeckel abgewandten Enden in einen geschlossenen Ring über. Die Geberzähne sind dabei durch Geberzahnaussparungen in einer zylindrischen Verlängerung des Primärmassedeckels gebildet.In one embodiment of the invention, the transmitter teeth merge into a closed ring at the ends facing away from the primary mass cover. The encoder teeth are formed by encoder tooth recesses in a cylindrical extension of the primary mass cover.
Die Enden der Geberzähne bzw. der geschlossene Ring sind in einer Ausführungsform der Erfindung mit dem Primärmasseblech verstemmt.In one embodiment of the invention, the ends of the encoder teeth or the closed ring are caulked with the primary mass plate.
Der geschlossene Ring weist in einer Ausführungsform der Erfindung eine Anprägung auf, sodass dessen Dicke verringert ist und eine leichtere plastische Verformung ermöglicht.In one embodiment of the invention, the closed ring has an embossing so that its thickness is reduced and allows easier plastic deformation.
