Embodiment Construction

[0020] figure 1 A partial view and a schematic representation of the centrifugal pendulum 1 are shown. For the general construction of the centrifugal pendulum see the cited prior art. The centrifugal pendulum 1 is formed from a support part 2 , which is only partially shown, and pendulum masses arranged distributed in the circumferential direction, of which only one pendulum mass 3 is shown. The pendulum mass 3 is received in a known manner on the support part 2 by means of a pendulum bearing (not shown) so as to pivot in a centrifugal force field and can assume a predetermined shape relative to the support part 2 at a predetermined pivot angle. Curves, such as swinging on a pendulum rail. The pivot angle of pendulum mass 3 is limited by means of elastic stops 4 , 5 , 6 . The elastic stops are formed by stop cushions 7 , 8 , 9 arranged on the pendulum mass 3 and stop surfaces 10 , 11 , 12 assigned to the carrier part 2 . The stop surfaces 10 , 11 , 12 are only simply out...

Abstract

The invention relates to a centrifugal force pendulum (1) having a support part (2) arranged around an axis of rotation and a pendulum mass (3) distributed in the circumferential direction and swingably received on the bracket part (2 , wherein a swing angle (SW) of the pendulum mass (3) is bounded in a damped mode by elastic stopper portions (4, 5, 6). In order to avoid generation of noise even in the elastic stopper portions (4, 5, 6), the vibration-damping characteristic curve of the elastic stopper portion (4, 5, 6) is progressively formed as the swing angle increases.

Description

technical field [0001] The invention relates to a centrifugal pendulum with a support part arranged around an axis of rotation and pendulum masses distributed in the circumferential direction and received pivotally on the support part, wherein the pivot angle of the pendulum mass is controlled by a stop The portion is bounded in an elastically damped manner. Background technique [0002] Centrifugal pendulums are used in speed-adapted torsional vibration isolators and are especially installed in drive trains with internal combustion engines subject to torsional vibrations. Torsional vibration isolation is achieved in that the pendulum mass suspended on the carrier part in a centrifugal force field stores the energy generated by the torque peaks as potential energy and then outputs it again to the drive train. It is known, for example, from WO 2014 / 082629 A1 that a centrifugal pendulum can be arranged on a single-mass flywheel, for example made of sheet metal. It is known, ...
