A vibration damping device 20 includes: a crank member 22 that is coupled to a driven member 15 via a first coupling shaft A1 and that is swingable about the first coupling shaft A1 along with rotation of the driven member 15; and an inertial mass body 24 that is coupled to the driven member 15 via the crank member 22 and a connecting rod 23 and that is swung about a center of rotation RC in conjunction with the crank member 22 along with rotation of the driven member 15. A component force of a centrifugal force that acts on the crank member 22 along with rotation of the driven member 15 in a direction that is orthogonal to the direction from the center of the first coupling shaft A1 toward the center of gravity G always acts on the crank member 22 as a restoring force that acts to return the inertial mass body 24 to the center of the swing range. The component force is maximum when the inertial mass body 24 is positioned at the center of the swing range.

A centrifugal pendulum, in particular for arrangement on a drive shaft of an internal combustion engine, has a drive ring which can be mounted on a drive shaft for rotation therewith, and a synchronizing ring which is freely rotatable relative to the drive ring. The axis of rotation of the drive ring and the axis of rotation of the synchronizing ring are identical. The centrifugal pendulum further includes at least one pendulum body which is mounted movably on the drive ring. The pendulum body is kinematically coupled via at least one coupling element to the synchronizing ring such that, in the event of a rotation of the synchronizing ring relative to the drive ring in a first direction, the coupling element deflects the pendulum body toward the axis of rotation.

A filtering mechanism for torque fluctuations is interposed between a crankshaft of an internal combustion engine and a transmission. This mechanism comprises a rotating member to be damped, an oscillating inertial flywheel rotating around the axis of revolution, and pivot-mounted modules allowing angular deflection of the oscillating inertial flywheel with respect to the member to be damped. The modules each have at least one oscillating arm pivoting radially with respect to the member to be damped and a kinematic connecting member between the oscillating arm and the oscillating inertial flywheel. When the mechanism rotates centrifugal forces on the oscillating arm produce a counteracting torque that tends to return the oscillating inertial flywheel and the member to be damped toward the equilibrium position. The counteracting torque increases with the rotation speed of the filtering mechanism and with the amplitude of the angular deflection.

A number of variations may include a torsional vibration damper having an input side, having an output side and having an energy store for the rotationally elastic coupling of the input and output sides in a circumferential direction, wherein, on the input or output side, there is arranged a mass part that is rotatable relative to the input or output side counter to the restoring force of a restoring apparatus.
