Abstract:
Hydrodynamic torque converter with a pump wheel which is received in a housing, a turbine wheel and a stator wheel, with a converter bypass clutch including an axially shiftable piston and a torsional vibration damper having an input part and an output part which are turnable relative to each other at least against the resistance of a restoring force furnished by energy storing elements installed between the input and output parts, as well as with a hub, characterized in that the turbine wheel and the piston are non-rotatably connected with the input part of the damper and the input part of the damper is connected to the hub by a connection which operates with angular play, the output part of the damper being connected with the hub by a connection which is devoid of angular play; the hub is provided with external teeth and the input part of the damper has internal teeth mating with the external teeth of the hub with angular play to thus establish a connection exhibiting an angular play, the output part of the damper having internal teeth mating with the external teeth of the hub without angular play to thus establish a connection without angular play.
