Abstract:
A torque converter having a converter housing connectable to a driving unit, a turbine wheel arranged within the converter housing and being rotatable about an axis of rotation, the turbine wheel having a turbine wheel shell and a turbine wheel hub connected to the turbine wheel shell, the turbine wheel hub being connectable to a converter driven shaft, the torque converter having a lockup clutch enabling selective rotational coupling of the converter housing with the turbine wheel and a torsional vibration damper arrangement in a power transmission path between the converter housing and the turbine wheel hub and between the turbine wheel shell and the turbine wheel hub, said torque converter comprising:a friction device connected in the power transmission path parallel to the torsional vibration damper and generating a selectively changeable frictional force, said friction device comprising a primary side fixedly coupled with a primary side of the torsional vibration damper and a secondary side fixedly coupled with a secondary side of the torsional vibration damper, said secondary side of said friction device being brought into adjustable frictional engagement with said primary side of said friction device.
