Der Erfindung liegt die Aufgabe zugrunde, eine Reibrostbildung im zentralen Verschraubungsbereich zu vermindern.Of the Invention is based on the object, a Reibrostbildung in the central Decrease screwing range.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Anspruchs 1.The Solution of this problem is inventively with the features of claim 1.
Gemäß der Erfindung ist bei einer Mitnehmerscheibe mit einem konzentrisch zu einer Rotationsachse der Mitnehmerscheibe ausgebildeten zentralen Verschraubungsbereich, einer äußeren Momentenübertragungsstruktur und einer den zentralen Verschraubungsbereich und die äußere Momentenübertragungsstruktur verbindenden Scheibenstruktur vorgesehen, dass die überbrückende Scheibenstruktur eine über den Abstand zur Rotationsachse variierende Wandstärke aufweist. Dies erlaubt es eine den Erfordernissen der Momentenübertragung ausreichende Biegeweichheit der Mitnehmerscheibe zu schaffen, wobei gleichzeitig im zentralen Verschraubungsbereich eine hohe Steifigkeit geschaffen werden kann, wodurch die Reibrostbildung reduziert wird. Da die zur Vermeidung von Reibrost erforderliche Steifigkeit der Mitnehmerscheibe mit einer entsprechend hohen Wandstärke im zentralen Verschraubungsbereich gemäß der Erfindung nicht für die gesamte radiale Erstreckung der Mitnehmerscheibe beibehalten wird, ergibt sich auch eine Gewichtsreduzierung gegenüber einer Mitnehmerscheibe, welche bei konstanter Wandstärke ausschließlich nach den Erfordernissen des zentralen Verschraubungsbereiches dimensioniert ist. Die Variation der Wandstärke über den Abstand zu der Rotationsachse hat ferner den Vorteil, dass die zur Erreichung einer Deformationen zulassenenden Biegeweichheit aus dem Stand der Technik bekannten Schwächungsöffnungen weniger komplex gestaltet werden können.According to the Invention is concentric with a drive plate with a concentric formed to a rotation axis of the drive plate central Bolting range, an external torque transmission structure and one the central bolting area and the outer one Provided torque transfer structure connecting pulley structure, that the bridging pane structure has an over Having the distance to the axis of rotation varying wall thickness. This allows one to meet the requirements of torque transmission to provide sufficient bending softness of the drive plate, wherein at the same time in the central bolting area a high rigidity can be created, whereby the Reibrostbildung is reduced. Since the stiffness required to avoid friction rust is the Drive plate with a correspondingly high wall thickness in the central bolting area according to the invention not for the entire radial extent of the drive plate is maintained, there is also a weight reduction compared a drive plate, which at constant wall thickness exclusively according to the requirements of the central bolting area is dimensioned. The variation of the wall thickness over the distance to the axis of rotation also has the advantage that the to achieve a bending softness allowing for deformations known in the art weakening openings less complex.
Gemäß einer bevorzugten Ausgestaltung der Erfindung sind der zentrale Verschraubungsbereich, die äußere Momentenübertragungsstruktur und die verbindende Scheibenstruktur einstückig ausgebildet, wobei gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung die Momentenübertragungsstruktur als Lochstruktur ausgebildet ist. Dies erleichtert die Herstellung der Mitnehmerscheibe.According to one preferred embodiment of the invention are the central bolted area, the external torque transmission structure and the connecting pane structure formed integrally, wherein according to another preferred embodiment the invention, the torque transmission structure as a hole structure is trained. This facilitates the production of the drive plate.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist die Variation der Wandstärke frei von Festigkeitssprüngen ausgebildet, wodurch eine Spannungsbildung und damit ein etwaiger Verschleiß vermieden werden können.According to one Another preferred embodiment of the invention is the variation the wall thickness formed free of strength jumps, whereby a voltage formation and thus a possible wear avoided can be.
Die Momentenübertragungsstruktur weist gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung eine Zahneingriffsstruktur für ein Triebmittel einer Anlassereinrichtung auf, so dass die Mitnehmerscheibe im Zusammenhang mit einer Anlassereinrichtung verwendbar ist, mit welcher ein Drehmoment auf eine Welle, insbesondere eine Kurbelwelle einer Brennkraftmaschine übertragen werden kann.The Momentum transmission structure has according to a Another preferred embodiment of the invention, a tooth engagement structure for a drive means of a starter device, so that the drive plate in connection with a starter device is usable, with which a torque on a shaft, in particular a crankshaft of an internal combustion engine can be transmitted.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung weist die Momentenübertragungsstruktur eine Kupplungsstruktur zum Anschluss an einem hydrodynamischen Wandler auf, so dass – wenn gleichzeitig eine Zahneingriffsstruktur für ein Triebelement einer Anlassereinrichtung vorgesehen ist – die Mitnehmerscheibe nicht nur beim Start der Brennkraftmaschine, sondern auch bei deren weiteren Betrieb nutzbringend eingesetzt ist.According to one Another preferred embodiment of the invention, the torque transmission structure a coupling structure for connection to a hydrodynamic converter on, so that - if at the same time a meshing structure for a drive element of a starter device is provided - the Drive plate not only at the start of the internal combustion engine, but is also used profitably in their further operation.
Weitere vorteilhafte Ausgestaltung und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung im Zusammenhang mit den Zeichnungen.Further advantageous embodiment and refinements of the invention result from the subclaims as well as from the description in connection with the drawings.
