Abstract

A hydrodynamic torque converter (1), comprising a turbine wheel (9) driven by an impeller (8) and connected to an output part, and comprising a housing (34), in which a torsional vibration damper (19) having several damper stages (17, 20) and a centrifugal force pendulum (11), and also a converter lockup clutch (18) connecting a housing and an output part (3), are accommodated. In order to avoid any striking of the pendulum masses of the centrifugal force pendulum in internal combustion engines having large oscillating angles driving the torque converter, a turbine damper is connected in the power flow upstream of the centrifugal force pendulum.
