Abstract
Description
Die vorliegende Erfindung betrifft eine Mitnehmerscheibe für eine drehmomentübertragende Koppelverbindung zwischen einer Kurbelwelle einer Brennkraftmaschine, insbesondere in einem Kraftfahrzeug, und einem Getriebeaggregat, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The present invention relates to a drive plate for a torque transmitting coupling connection between a Crankshaft of an internal combustion engine, in particular in a motor vehicle, and a transmission unit, having the features of the preamble of Claim 1.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Mitnehmerscheibe der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass vergleichsweise enge Formtoleranzen erzielbar sind.The The present invention addresses the problem of for a drive plate of the type mentioned a to provide improved embodiment, in particular characterized in that comparatively tight shape tolerances achievable are.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, den Scheibenkörper so auszugestalten, dass der Ringkörper über eine axiale Kontaktzone am Scheibenkörper anschweißbar ist, wobei gleichzeitig ein Ringspalt realisiert wird, der radial außen an die Kontaktzone angrenzt und sich im Profil zur Kontaktzone hin verjüngt. Durch diese Bauweise ist es insbesondere möglich, die Schweißverbindung zwischen Scheibenkörper und Ringkörper mittels eines Laserschweißverfahrens herzustellen, wobei ein entsprechender Laserstrahl von radial außen durch den Ringspalt zur Kontaktzone gelangt. Die vorgeschlagene, für ein Laserschweißverfahren geeignete Konstruktion zeichnet sich dadurch aus, dass sie mit erheblich engeren Toleranzen für Lage und Form der Mitnehmerscheibe herstellbar ist. Dies lässt sich insbesondere darauf zurückführen, dass beim Laserschweißen der Wärmeeintrag und somit ein damit einhergehender Verzug der miteinander zu verschweißenden Bauteile vergleichsweise gering ist. Gleichzeitig trägt auch die axiale Kontaktierung zwischen Ringkörper und Scheibenkörper dazu bei, dass die beim Schweißen auftretenden bleibenden Verformungen vergleichsweise gering ausfallen. Durch die vorgeschlagene, geschickte Anordnung zwischen Scheibenkörper und Ringkörper lässt sich die Mitnehmerscheibe somit vergleichsweise einfach mit relativ engen Toleranzen herstellen.The The invention is based on the general idea of the disk body in such a way that the ring body over a axial contact zone weldable to the disk body is, at the same time an annular gap is realized, the radial outside adjacent to the contact zone and in profile to Contact zone tapers. This construction makes it special possible, the welded joint between disk body and ring body by means of a laser welding process produce, with a corresponding laser beam from the outside radially passes through the annular gap to the contact zone. The proposed, construction suitable for a laser welding process is characterized by the fact that they have considerably narrower tolerances for position and shape of the drive plate is produced. This can be attributed in particular to that during laser welding the heat input and thus a concomitant delay of the welded together Components is comparatively low. At the same time contributes also the axial contact between annular body and disk body This helps to ensure that the permanent deformation occurring during welding comparatively low. By the proposed, skillful Arrangement between disk body and ring body Thus, the drive plate can be comparatively easy with produce relatively tight tolerances.
