Description
Die Erfindung betrifft eine Schwungradausbildung
nach dem Oberbegriff von Patentanspruch 1. Eine solche Schwungradausbildung
ist aus der
Verbund-Schwungradausbildungen für Fahrzeugmotoren werden laufend verwendet. Typisch für solche Schwungradausbildungen ist, dass sie erste und zweite Schwungräder mit einem dazwischen angeordneten Proportional-Dämpfungsmechanismus aufweisen.Composite flywheel training for vehicle engines are used continuously. Typical of such flywheel designs is that they have first and second flywheels with one in between Proportional damping mechanism.
Das erste Schwungrad der Schwungradausbildung ist mit der Kurbelwelle eines Motors verbunden, und eine Kupplung ist an dem zweiten Schwungrad montiert. Ein Lager ist durch Presspassung an der Nabe des ersten Schwungrads befestigt. Das zweite Schwungrad ist durch das Lager drehbar an dem ersten Schwungrad gehalten.The first flywheel of flywheel training is connected to the crankshaft of an engine, and a clutch is mounted on the second flywheel. A bearing is by press fit attached to the hub of the first flywheel. The second flywheel is rotatably supported on the first flywheel by the bearing.
Dichtungsplatten sind an dem zweiten Schwungrad derart angeordnet, dass sie das Lager axial flankieren und verhindern, dass Schmierfett von dem Proportional-Dämpfungsmechanismus aus der Ausbildung austritt, und die dienen auch als Isolatoren gegen Wärmeübertragung von der Kupplung. Die Dichtungsplatten werden durch Plattenfeder gegen das Lager gedrückt, und zwar so, dass die Abdichtung gegen austretendes Schmierfett sichergestellt und darüber hinaus der Lagerkörper an axialen Taumelbewegungen gehindert wird, so dass das Lager in bezug auf seine Achse nicht abweichen kann.Sealing plates are on the second flywheel arranged in such a way that they axially flank and prevent the bearing, that grease from the proportional damping mechanism from training emerges, and they also serve as insulators against heat transfer from the clutch. The sealing plates are made by plate spring pressed against the camp, in such a way that the seal against escaping grease ensured and above out the bearing body is prevented from axial wobble, so that the bearing with respect cannot deviate on its axis.
Das Drehmoment wird über den Proportional-Dämpfungsmechanismus von dem ersten Schwungrad auf das zweite Schwungrad übertragen und dann wiederum von dem zweiten Schwungrad über die Kupplung auf ein getriebewärts gerichtetes Element.The torque is over the Proportional damping mechanism transferred from the first flywheel to the second flywheel and then again from the second flywheel via the clutch to a gear-facing element.
Auch bei dem in der eingangs erwähnten
Aus der
Aufgabe der Erfindung ist es, eine Schwungradausbildung bzw. nach dem Oberbegriff des Anspruchs 1 derart auszubilden, dass der Einbau des Lagers leichter vonstatten geht, Taumelbewegungen verringert werden und die Abdichtung verbessert wird. Weiterhin gilt es, eine übermäßige Abnutzung eines solchen in eine Schwungradausbildung eingebauten Lagers zu verhindern.The object of the invention is a Flywheel training or according to the preamble of claim 1 such to make it easier to install the bearing, Swashes are reduced and the seal is improved. Furthermore, excessive wear of a to prevent such built in a flywheel bearing.
Die der Erfindung zugrundeliegende Aufgabe wird bei einem Gegenstand nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst.The basis of the invention Task becomes with an object according to the preamble of the claim 1 solved by its characteristic features.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the Invention are the subject of the dependent claims.
Dazu weist eine Schwungradanordnung nach der Erfindung ein an ein Motorausgangsteil anschließbares erstes Schwungrad, ein zweites Schwungrad, an welchem eine Kupplung montiert werden kann, ein Lager, über welches das erste Schwungrad das zweite Schwungrad drehbar hält, und eine Dämpfungseinheit auf. Die Dämpfungseinheit enthält einen Proportional-Dämpfungsmechanismus zur Dämpfung von Torsionsschwingungen durch den Widerstand eines zähflüssigen Mediums.A flywheel arrangement demonstrates this the invention a first connectable to an engine output part Flywheel, a second flywheel on which a clutch is mounted can, a camp, about which the first flywheel rotatably holds the second flywheel, and a damping unit on. The damping unit contains a proportional damping mechanism for cushioning torsional vibrations caused by the resistance of a viscous medium.
Das Lager weist einen Lagerkörper mit einer inneren Schale auf, die mit dazwischen vorgesehenen Rollkörpern konzentrisch in einer äußeren Schale angeordnet ist, sowie Dichtungselemente und Andrückelemente. Die Dichtungselemente sind zwischen die innere und äußere Schale eingepasst. Die Andrückelemente befinden sich ebenfalls zwischen inneren und äußeren Schale und grenzen an die Außenseiten der Dichtungselemente an und drücken dort die Dichtungselemente in Richtung zueinander.The bearing has a bearing body an inner shell, concentric with the rolling elements provided in between in an outer shell is arranged, as well as sealing elements and pressing elements. The sealing elements are between the inner and outer shell fitted. The pressure elements are also between the inner and outer shell and adjoin the outsides of the sealing elements and press there the sealing elements towards each other.
Demzufolge ist das Lager innen abgedichtet und gegen Taumelbewegungen eingeengt. Dadurch sind separate externe Elemente zur Abdichtung und zur Verhinderung von Taumelbewegungen entbehrlich. Dies ermöglicht einen leichteren Einbau des Lagers in die zugehörige Vorrichtung.As a result, the bearing is sealed on the inside and restricted against wobble. This makes separate external ones Elements for sealing and preventing wobbling dispensable. this makes possible easier installation of the bearing in the associated device.
Das Lager ist somit gegen Taumelbewegungen eingeengt, wodurch wiederum verhindert wird, dass das durch das Lager gehaltene zweite Schwungrad in axialer Richtung taumelt. Dadurch wird die Abnutzung des Lagers verhindert.The bearing is therefore against wobbling restricted, which in turn prevents that by the Bearing held second flywheel tumbles in the axial direction. This will prevents wear of the bearing.
