ABSTRACT:
A device for damping vibrations, in particular a torsion vibration damper with a primary component and a secondary component, coupled together through a torque transfer device and a damping coupling device. The torque coupling device includes a ramp mechanism for converting a rotation of one of the two elements, primary component or secondary component, into an axial force proportional to the input moment, which acts upon the other element. A device for compensating the resulting axial forces for generating an opposing force, opposing the resulting axial force, wherein the input moment is designed for a mean input torque. A conversion device is also provided, which directly converts an occurring force difference between the resulting axial force and the opposite force into a control variable for operating an actuation device in the device for damping vibrations, whereby an adaptation of the opposite force is performed.
