Embodiment Construction

[0039] figure 1 and figure 2 A centrifugal pendulum device 2 is shown. In this figure, the centrifugal pendulum device 2 has mutually opposite axial directions 4, 6, mutually opposite axial directions 8, 10 and mutually opposite circumferential directions 12, 14 according to corresponding arrows, wherein the centrifugal pendulum device 2 is rotatable about an axis of rotation 16 which extends axially 4 , 6 .

[0040] The centrifugal pendulum device 2 has a disk-shaped or plate-shaped pendulum bracket 18 , it can also be said to have a disk-shaped or plate-shaped bracket. More precisely, the disc-shaped or plate-shaped pendulum carriage 18 extends substantially along the plane formed by the radial directions 8 and 10 , wherein the pendulum carriage 18 is disc-shaped. The pendulum carrier 18 is fixed in a non-rotatable manner, for example via fastening openings 19 in the radial direction 10 , on a component arranged on the torque transmission path of the drive train, so that...

Abstract

The invention relates to a centrifugal pendulum device (2) having a rotatable pendulum bracket (18) and at least one pendulum weight (20) arranged on the pendulum bracket. The pendulum weight moves between two final positions relative to the pendulum bracket (18) through at least one guide element (46, 48) (which extends in a guide slot (50, 52) between the pendulum bracket (18) and the pendulum weight (20)). A damper element (54) is attached to the pendulum bracket (18). By the damper element (54), the pendulum weight (20) supports or is supported on the pendulum bracket (18) before reaching one of the final positions (preferably two final positions). The damper element (54) is arranged in a groove (56) of the pendulum bracket (18). In addition, the invention also relates to a torsion damper provided with the centrifugal pendulum device.

Description

technical field [0001] The invention relates to a centrifugal pendulum device with a rotatable pendulum bracket and at least one pendulum weight arranged on the pendulum bracket, the pendulum weight passing through at least one guide element bracket and pendulum counterweight) is moved between two end positions relative to the pendulum bracket, wherein a damping element is fastened on the pendulum bracket, by means of which , the pendulum weight is supported or supported on the pendulum carriage until it reaches one of its final positions. Background technique [0002] Various centrifugal pendulum devices are known in practice, which dampen rotational vibrations in the drive train. In the known centrifugal pendulum device, a rotatable pendulum carrier is provided, which is fastened in a non-rotatable manner to a component arranged in the torque transmission path of the drive train. At least one pendulum weight is arranged on the pendulum bracket. The pendulum weight is mo...
