摘要： A torsional vibration damper has an input, an output and an intermediate mass arranged therebetween, a first plurality of spring elements coupled between the input and the intermediate mass that form a first stage, a second plurality of spring elements coupled between the intermediate mass and the output that form a second stage of the torsional vibration damper, at least one damper mass to damp the vibration component of the rotational movement. The first stage of the torsional vibration damper has a progressive first characteristic with at least one transition point. The second stage of the torsional vibration damper has a progressive, second characteristic with at least one transition point. All of the transition points of the first characteristic and the second characteristic are spaced apart from one another with respect to torque.

摘要： A torque converter device and to a method for controlling a liquid circuit of a torque converter device. The torque converter device includes a housing arrangement and a hydrodynamic device arranged in the housing arrangement. The hydrodynamic device include an impeller wheel connected on the input side to a driveshaft via the housing arrangement, a turbine wheel connected to an output shaft, and a stator wheel. The wheels collectively form a circuit filled with a liquid, that can be supplied with liquid by an external supply device. The torque converter device is constructed such that it actuates at least one flow control element for controlling the flow of liquid for the torque converter device in the circuit actively and/or passively depending on a difference in speed between the impeller wheel and the turbine wheel of the hydrodynamic device.

摘要： 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.
