Abstract
A hydrodynamic torque converter having a pump wheel accommodated in a housing, a turbine wheel, which can be driven by the pump wheel, and a torsional vibration damper, where the torsional vibration damper has a damper input drive component and a damper output drive component, which can rotate to a limited degree with respect to the damper input drive component to oppose the action of at least two damper stages which are operatively connected in series and which each have at least one energy storage element, where the torsional vibration damper also has an intermediate damper component, which is arranged operatively between the damper stages and which directly or indirectly accommodates a vibration absorber, where the energy storage elements of the damper stages are substantially arranged on a common radius, where the vibration absorber is arranged adjacent to the torsional vibration damper in the axial dimension.
