ABSTRACT:
For damping torsion vibrations in the drive line of a motor vehicle which contains a torsion vibration damper (5) between its internal combustion engine (1) and its gearbox (11), there is coupled to the output of the torsion vibration damper (5) an electric motor driven torque buffer (23) which compensates for any fluctuations in torque still present at the output of the torsion vibration damper (5) and occasioned by the firing sequence of the internal combustion engine (1). The torque buffer (23) is constructed after the fashion of a polyphase synchronous motor, the number of pairs of poles and possibly the rotary speed at which the magnetic fields rotates being so chosen that the angular cycle of the torque fluctuation exerted by the magnetic field on the rotor (31) of the torque buffer is equal to the angular cycle of the torque fluctuation originating from the firing sequence of the internal combustion engine (1). A control circuit (37) regulates the phasing of the magnetic field and its intensity.
