Arrangement for compensating alternating torques and vibrations in a motor vehicle drive train

摘要

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.
