Hydro-dynamic coupling device, especially a torque converter

摘要

The hydrodynamic coupling device, particularly torque converter, has a housing (12) that is filled with a fluid, an impeller (18), and a turbine wheel (24) that is arranged in an interior (22) of the housing. A bypass clutch arrangement (44) is provided with a group (46) of friction elements, which are coupled with the housing for a common rotation around an axis of rotation (A). Another group (48) of friction elements is coupled with a drift organ for a common rotation around an axis of rotation.
