Abstract
A torque converter has a converter housing which is connectable with a drive shaft, a turbine wheel having a turbine wheel shell and a turbine wheel hub arranged in the converter housing so as to be rotatable about an axis of rotation and which is connectable with a converter driven shaft. A lockup clutch is provided for optional coupling of the turbine wheel with the converter housing. A torsional vibration damper arrangement in a force flow path between the converter housing and the turbine wheel hub, includes the following: a first transmission arrangement, a and second transmission arrangement rotatable about the axis of rotation with and with respect to the first transmission arrangement and with respect to the first transmission arrangement, a coupling arrangement having a torque-transmitting connection with the first transmission arrangement by a first coupling area and a torque-transmitting connection with the second transmission arrangement by a second coupling area. The first coupling area and/or the second coupling area have at least one guide portion contactable with a guide path provided at a respective one of the transmission arrangements and is movable along the guide path during relative rotation between the first transmission arrangement and the second transmission arrangement.
