1. A damping pendulum suspension (1), for a pendulum damper in a vibration system, comprising:
a Cardan joint (1) having two cross-connected shafts (1.3), and
a holding device (1.7) for receiving and holding a pendulum rod with a pendulum mass,
wherein each of the two shafts (1.3) of the Cardan joint (1.1) has (i) at least one transmission gearing (1.2),
(ii) at least one rotating damping unit (1.4) which generates eddy current, and the damping element (1.4) being attached, in each case, to a rapidly rotating gearing output side (1.2),
(iii) an elastomeric torsional bearing, in a shape of a bushing (19), is connected to each of the shafts (1.3) via a slowly rotating gearing input side, and
(iv) a torque arm (23) is provided, which transmits only circulating torque, and is mounted largely load-free in a remaining spatial axes, so that an entire angle of movement of the damper is shifted into the gearing rotation.
