Abstract

A device for damping vibrations with an energy recovery capability includes an input shaft rotatable about the input shaft longitudinal axis with an alternating rotational direction by a component that vibrates relative to the device. A freewheel device is connected to the input shaft on the drive side and at least indirectly to a generator on the output side, the generator being capable of converting the kinetic rotational energy into electric energy and transferring said energy to an energy storage element, and the freewheel device includes a first and a second freewheel, each being rotationally fixed to the input shaft on the drive side and arranged so as to lock in opposite directions of rotation. The second freewheel is connected to a reversing gear mechanism on the output side, and the reversing mechanism and the first freewheel are at least indirectly connected to the generator on the output side.
