Description
Die Erfindung betrifft ein Zweimassenschwungrad mit einer Primärseite und einer Sekundärseite, die entgegen der Wirkung mindestens eines Energiespeichers gegeneinander verdrehbar sind, wobei zwischen der Primärseite und der Sekundärseite eine Reibeinrichtung angeordnet ist und wobei die Primärseite einen Primärmasseflansch und einen Primärmassedeckel umfasst.The invention relates to a dual-mass flywheel with a primary side and a secondary side, which can be rotated against one another against the action of at least one energy store, a friction device being arranged between the primary side and the secondary side, and wherein the primary side comprises a primary mass flange and a primary mass cover.
Bei einem Zweimassenschwungrad (ZMS) ist die Anordnung einer Reibeinrichtung innen zwischen Primärmasseflansch und Sekundärflansch bekannt. Dabei greift eine Kunststoffscheibe (Reibsteuerscheibe) in einen Flansch ein und erzeugt ab einem gewissen Freiwinkel eine zusätzliche Reibung. Durch diese Reibung kann das Motor-Startverhalten verbessert werden, da durch die Reibung dem Verdrehen von Primärgegenüber Sekundärseite entgegengewirkt wird. Bei derartigen Reibeinrichtungen liegt die Kunststoffscheibe entweder an dem Primärmasseflansch an oder ist zwischen einer Stützscheibe und einem Stützblech durch eine Tellerfeder eingeklemmt. Nachteilig bei der bekannten Anordnung ist, dass zwischen Primärmasseflansch und Sekundärflansch ausreichender Bauraum zur Verfügung stehen muss.In the case of a dual mass flywheel (DMF), the arrangement of a friction device inside between the primary mass flange and the secondary flange is known. A plastic disc (friction control disc) engages in a flange and creates additional friction from a certain clearance angle. This friction can improve the engine starting behavior, since the friction counteracts the twisting of the primary and secondary sides. In such friction devices, the plastic disk either lies against the primary mass flange or is clamped between a support disk and a support plate by a plate spring. A disadvantage of the known arrangement is that sufficient space must be available between the primary mass flange and the secondary flange.
Eine Aufgabe der Erfindung ist es daher, eine alternative Lösung insbesondere bei kleinem Bauraum zwischen Primärmasseflansch und Sekundärflansch anzugeben.It is therefore an object of the invention to provide an alternative solution, particularly in the case of a small installation space between the primary mass flange and the secondary flange.
Dieses Problem wird durch ein Zweimassenschwungrad nach Anspruch 1 gelöst. Bevorzugte Ausführungsformen, Ausgestaltungen oder Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This problem is solved by a dual mass flywheel according to
Das oben genannte Problem wird insbesondere gelöst durch ein Zweimassenschwungrad mit einer Primärseite und einer Sekundärseite, die entgegen der Wirkung mindestens eines Energiespeichers gegeneinander verdrehbar sind, wobei zwischen der Primärseite und der Sekundärseite eine Reibeinrichtung angeordnet ist und wobei die Primärseite einen Primärmasseflansch und einen Primärmassedeckel umfasst, wobei die Reibeinrichtung zwischen dem Primärmassedeckel und der Sekundärseite angeordnet ist. Vorzugsweise ist die Reibeinrichtung zwischen der Innenseite des Primärmassedeckels und einem Sekundärflansch oder einer mit dem Sekundärflansch fest verbundenen, insbesondere vernieteten, sekundärseitigen Nabe angeordnet.The above-mentioned problem is solved in particular by a dual-mass flywheel with a primary side and a secondary side, which can be rotated against one another against the action of at least one energy store, a friction device being arranged between the primary side and the secondary side, and the primary side comprising a primary mass flange and a primary mass cover, wherein the friction device is arranged between the primary mass cover and the secondary side. The friction device is preferably arranged between the inside of the primary mass cover and a secondary flange or a hub, which is firmly connected to the secondary flange, in particular riveted, on the secondary side.
Die Reibeinrichtung umfasst in einer Ausführungsform der Erfindung einen Reibring, der in axialer Richtung durch Befestigungsmittel an der Primärseite festgelegt und reibschlüssig in Umfangsrichtung mit dieser gekoppelt ist. Der Reibring umfasst dazu vorzugsweise eine radial nach außen verlaufenden Reibscheibe, die in Umfangsrichtung reibschlüssig mit der Primärseite gekoppelt ist. Die Reibschlüssige Kopplung erfolgt in einer Ausführungsform der Erfindung mittels eines an dem Primärmassedeckel befestigten Halteblechs und einer an diesem befestigten Tellerfeder, zwischen denen die Reibscheibe eingeklemmt ist.In one embodiment of the invention, the friction device comprises a friction ring which is fixed in the axial direction by fastening means on the primary side and is frictionally coupled to it in the circumferential direction. For this purpose, the friction ring preferably comprises a radially outwardly running friction disk which is coupled to the primary side in a frictionally locking manner. In one embodiment of the invention, the frictional coupling takes place by means of a holding plate fastened to the primary mass cover and a plate spring fastened to it, between which the friction disc is clamped.
Die Reibeinrichtung umfasst in einer Ausführungsform der Erfindung einen Reibring mit Mitteln zur formschlüssigen Befestigung in Umfangsrichtung an der Sekundärseite. Die formschlüssige Befestigung weist in einer Ausführungsform der Erfindung ein Spiel in Umfangsrichtung auf.In one embodiment of the invention, the friction device comprises a friction ring with means for positive fastening in the circumferential direction on the secondary side. In one embodiment of the invention, the form-fitting fastening has play in the circumferential direction.
Ein weiterer Vorteil dieser Konstruktion ist es, dass die Hauptvernietung des ZMS/ Dämpfers weiter nach innen gelegt und somit Platz für ein Drehmomentbegrenzer, Fliehkraftpendel oder Innendämpfer geschaffen werden kann bei gleichzeitigem Einsatz einer Reibsteuerscheibe.Another advantage of this design is that the main rivet of the DMF / damper is placed further inwards, thus creating space for a torque limiter, centrifugal force pendulum or inner damper while using a friction control disc.
