Embodiment Construction

[0070] With the aid of the pendulum suspension with universal joint according to the invention, a large number of different pendulum dampers can be equipped for wind power installations and other tall, slender buildings.

[0071] Shock absorbers with brakes and with or without transmission:

[0072] Since a higher braking force can be achieved with disc brakes than with eddy currents, an increase in rotational speed is not necessarily required in the case of a cardan coupling. This means that no transmission is required for this embodiment with disc brakes.

[0073] In order to achieve even higher damping forces with relatively low braking forces, it is also possible to combine transmissions with brakes (for example disc brakes). In such systems, damping can be achieved via eddy currents and disc brakes are only used to partially reinforce the dampers. It is also possible, for example, to fasten the shock absorber with the brake for maintenance work.

[0074] It is also pos...

Abstract

The invention relates to a new type of independently damping pendulum suspension for pendulum dampers for use in tall slender constructions and technical installations, more particularly wind turbines. The invention relates more particularly to a Cardan joint equipped with damping elements and mounted at the other end opposite the pendulum mass, which Cardan joint is able, despite the small motions there, to sufficiently damp the oscillations of the pendulum produced by disturbing frequencies.

Description

technical field [0001] The present invention relates to a novel independent damping pendulum suspension for pendulum dampers used in tall and slender buildings and technical installations, in particular in wind power installations. [0002] In particular, the invention relates to a universal joint (Kardangelenk) equipped with a damping element, mounted at the other end of the opposite pendulum mass (Pendelmasse) with two shafts connected via a cross section, although at this point The small movability that exists at is still able to adequately dampen the vibrations of the pendulum due to disturbing frequencies. Background technique [0003] Tall and slender buildings and installations are subject to special vibration situations which have to be taken care of by technical measures so that no damage or premature fatigue processes occur. This applies in particular to wind power installations, which, due to their rapid technical further development over the past few years, are ...
