A coupling arrangement is provided with a vibration reduction device and with a clutch device. The vibration reduction device has at least one torsional vibration damper, an input connected to a drive, and an output connected to the clutch device by which a connection between the vibration reduction device and a driven end is at least substantially produced in a first operating state, and this connection is at least substantially cancelled in a second operating state. The vibration reduction device has a mass damper system that cooperates with the torsional vibration damper and is connected to the output of the vibration reduction device.

Coupling arrangement having a vibration reduction device and having a coupler device

A control device for a drivetrain of a vehicle, includes a drive engine, a starting element, and a coupling element. The coupling element brakes a secondary side when the control device receives an input signal indicating a switching off of the drive engine. The starting element includes a mass damper torsional damper arrangement with at least one damper mass. The starting element is coupled with the drive engine by a primary side and with the mass damper torsional damper arrangement by a secondary side so as to be fixed with respect to relative rotation, and the coupling element is constructed to brake the secondary side by coupling with the primary side of the starting element and/or by coupling with a reference component that stationary when the vehicle is stationary. This makes it possible to find a better compromise between comfort, responsiveness, economical, and ecological aspects of the drivetrain.
