Abstract
A torque converter for transferring torque from an input shaft to an output shaft, having a turbine wheel, an impeller connected to the input shaft to drive the turbine wheel hydrodynamically, a centrifugal force pendulum connected to the turbine wheel to damp torsional vibrations, a first torsion damper to drive the output shaft by means of the turbine wheel, and a converter clutch and a second torsion damper for selective torsionally damped coupling of the input shaft with the turbine wheel. One of the torsion dampers in this case includes two torsion damper elements, which are arranged in series with each other.
