An arrangement for compensating for alternating torques and reducing vibrations in the drive train of a motor vehicle includes three flywheel masses and two clutches in a common housing and integrates an electromechanical converter capable of being operated as an electric motor and as an generator. The first two flywheel masses are arranged in the manner of a dual-mass flywheel for the purpose of reducing the vibrations capable of being transmitted into the transmission by the crankshaft and the third flywheel mass is driven from the first flywheel mass through planet wheels so that it rotates in the direction opposite to the direction of rotation of the crankshaft. The third flywheel mass is formed, on its radially outer circumference as a rotor for an electromechanical converter and can be disconnected from the crankshaft by a clutch positioned between the planet wheels and the second flywheel mass while the other clutch serves as driving clutch.

To balance varying moments and reduce vibrations in the drive train of a motor vehicle, three flywheel masses and a clutch are provided in a common housing. Two flywheel masses are connected by springs to provide a dual-mass flywheel for reducing vibrations which can be transmitted into the transmission from the crankshaft and the third flywheel mass is connected to the first flywheel mass by planet gears mounted in fixed relation to the housing so that the direction of rotation of the third flywheel mass is opposite to the direction of rotation of the crankshaft.
