A clutch assembly for coupling an internal combustion engine to a drive train of a motor vehicle, having a frictional clutch for coupling a drive shaft of the internal combustion engine to an output shaft, an actuating device for opening and/or closing the frictional clutch, an eddy current brake for introducing an actuating force into the actuating apparatus, and a control apparatus for applying a defined, predetermined current to the eddy current brake, wherein the control apparatus is configured, in an acceleration phase of a torsional vibration of the drive shaft, to specify a current for opening, in particular for adjusting a slip operation, of the frictional clutch and, in a deceleration phase of the torsional vibration of the drive shaft, to specify a current for closing, in particular for rotationally-fixed, frictional coupling, of the frictional clutch for the eddy current brake. By changing the operating state of the frictional clutch using the eddy current brake, only low inertial masses of the actuating apparatus must be moved by a correspondingly low energy input in order to achieve an active dampening of torsional vibrations, such that an at least partial dampening of torsional vibrations in a drive train of a motor vehicle is enabled in an energy-efficient manner. |

1. A clutch assembly for coupling an internal combustion engine to a drive train of a motor vehicle, comprising a frictional clutch for coupling a drive shaft of the internal combustion engine to an output shaft, an actuating device for at least one of opening or closing the frictional clutch, an eddy-current brake that introduces an actuating force into the actuating device, and a control device to electrify the eddy-current brake with a defined predetermined current, the control device being configured in an acceleration phase of a torsional vibration of the drive shaft to provide current for opening of the frictional clutch and in a deceleration phase of the torsional vibration of the drive shaft to provide current for closing of the frictional clutch for the eddy-current brake. |
