Title: CENTRIFUGAL PENDULUM
Abstract:
The invention relates to a centrifugal pendulum (1), having a pendulum carrier (2) arranged for rotation about an axis of rotation (d) and a plurality of pendulums (7) having a specified pendulum mass and held on the pendulum carrier for oscillation perpendicular to the axis of rotation (d), the pendulums being distributed over the circumference on the pendulum carrier, wherein a spring element (11) effective in the circumferential direction and having a specified spring rate is provided between each pair of pendulums (7) adjacent in the circumferential direction. In order to improve the synchronization of the pendulums (7) in the pendulum motion thereof, pendulums (7) and spring elements (11) are matched to a specified excitation order while taking into account the gravitational force acting on the pendulums (7).
