Abstract
Description
Die Erfindung betrifft eine Fliehkraftpendeleinrichtung, insbesondere zur Verwendung in einem Antriebsstrang eines Kraftfahrzeuges, mit mehreren Fliehkraftpendeln, die an einem Pendelträger angebracht und relativ zu diesem bewegbar sind.The invention relates to a centrifugal pendulum device, in particular for use in a drive train of a motor vehicle, with a plurality of centrifugal pendulums, which are mounted on a pendulum carrier and movable relative thereto.
Eine gattungsgemäße Fliehkraftpendeleinrichtung ist beispielsweise aus der
Insbesondere bei niedrigen Drehzahlen und den dabei auftretenden hohen Momentenschwankungen einer Brennkraftmaschine kann die Dämpfungswirkung eines Einmassenschwungrades günstiger sein als die Dämpfungswirkung einer Fliehkraftpendeleinrichtung. Insbesondere bei so hohen Momentenschwankungen, die ein Anschlagen der Pendelmassen bewirken, ist die Funktion der Fliehkraftpendeleinrichtung in der Regel nicht mehr gegeben, sodass eine Schwingungsisolierung nicht mehr bewirkt wird.In particular, at low speeds and the occurring high torque fluctuations of an internal combustion engine, the damping effect of a Einmassenschwungrades be cheaper than the damping effect of a centrifugal pendulum device. In particular, with such high torque fluctuations, which cause a striking of the pendulum masses, the function of the centrifugal pendulum device is generally no longer present, so that a vibration isolation is no longer effected.
Eine Aufgabe der Erfindung ist es daher, die Wirkungsweise der Fliehkraftpendeleinrichtung auf einen Drehzahlbereich oberhalb einer Minimaldrehzahl zu beschränken und die Pendelwirkung unterhalb dieser Drehzahl einzuschränken oder gar zu unterbinden.An object of the invention is therefore to limit the action of the centrifugal pendulum device to a speed range above a minimum speed and restrict the pendulum action below this speed or even to prevent.
Diese Aufgabe wird gelöst durch eine Fliehkraftpendeleinrichtung, insbesondere zur Verwendung in einem Antriebsstrang eines Kraftfahrzeuges, mit mehreren Pendelmassen, die an einem Pendelträger angebracht und relativ zu diesem bewegbar sind, wobei die Fliehkraftpendeleinrichtung ein Mittel umfasst, das mindestens eine Pendelmasse drehzahlabhängig in ihrer Bewegung bremst. Unter Bremsen wird hier auch ein reibschlüssiges oder formschlüssiges Festlegen verstanden. Üblicherweise sind mehrere Pendelmassen an dem Pendelträger angeordnet, wobei dann vorzugsweise jeder Pendelmasse oder zumindest jedem paarweise beiderseits des Pendelträgers angeordneten Paar von Pendelmassen ein solches Mittel zugeordnet ist.This object is achieved by a centrifugal pendulum device, in particular for use in a drive train of a motor vehicle, with a plurality of pendulum masses which are mounted on a pendulum carrier and movable relative thereto, wherein the centrifugal pendulum means comprises means that brakes at least one pendulum mass speed-dependent in their movement. Braking is understood here as a frictional or positive fixing. Typically, a plurality of pendulum masses are arranged on the pendulum carrier, in which case preferably each pendulum mass or at least each pairs of both sides of the pendulum carrier arranged pair of pendulum masses such means is assigned.
Das Mittel übt vorzugsweise eine Reibkraft auf die Pendelmasse bezüglich dessen Bewegung relativ zu dem Pendelträger aus. Vorzugsweise umfasst das Mittel eine Schwungmasse, die durch einen Energiespeicher in radialer Richtung auf eine Reibfläche der Pendelmasse gedrückt wird. Entgegengesetzt zur Andrückkraft des Energiespeichers wirkt bei drehender Fliehkraftpendeleinrichtung die Zentrifugalkraft auf die Schwungmasse, sodass die Gesamtkraft und damit die Reibkraft drehzahlabhängig ist. Der Energiespeicher umfasst vorzugsweise mindestens eine Feder, die zwischen der Schwungmasse und dem Pendelträger eingespannt ist. Die Wirkrichtung der Feder verläuft dabei vorzugsweise im Wesentlichen radial.The means preferably exerts a frictional force on the pendulum mass with respect to its movement relative to the pendulum carrier. Preferably, the means comprises a flywheel, which is pressed by an energy store in the radial direction on a friction surface of the pendulum mass. Opposite to the pressure force of the energy accumulator, centrifugal force acts on the flywheel when the centrifugal pendulum device rotates, so that the total force and thus the frictional force are speed-dependent. The energy storage preferably comprises at least one spring which is clamped between the flywheel and the pendulum carrier. The direction of action of the spring preferably extends substantially radially.
In einer weiteren Ausführungsform ist vorgesehen, dass das Mittel die Pendelmasse bezüglich ihrer Bewegung relativ zu dem Pendelträger drehzahlabhängig festlegt. Dies wird vorzugsweise bewirkt, indem das Mittel eine formschlüssige Festlegung bewirkt. Vorzugsweise ist dazu vorgesehen, dass das Mittel eine Sperrrolle umfasst, die an der Schwungmasse angeordnet ist, und in eine Vertiefung der Pendelmasse eingreifen kann.In a further embodiment it is provided that the means determines the pendulum mass with respect to their movement relative to the pendulum carrier speed-dependent. This is preferably accomplished by the means effecting a positive locking. Preferably, it is provided that the means comprises a locking roller, which is arranged on the flywheel, and can engage in a recess of the pendulum mass.
