Abstract
The invention relates to a hydrodynamic assembly with a hydrodynamic retarder comprising a rotor and a stator; with a hydrodynamic clutch, comprising a primary wheel and a secondary wheel; the rotor and the stator of the retarder as well as the primary wheel and the secondary wheel of the clutch respectively form with each other a torus-shaped working chamber; the rotor of the retarder and the secondary wheel of the clutch are joined to each other in torsion-proof manner, in axial direction in series in a back to back arrangement; the primary wheel has a drive connection to a first input shaft; the rotor and the secondary wheel have a drive connection to a second input shaft; The inventive hydrodynamic assembly is characterized in that the rotor and the secondary wheel can be moved jointly in axial direction between a first position, in which the secondary wheel is opposite the primary wheel at a minimum axial distance and the rotor is opposite the stator at a maximum axial distance, and a second position, in which the secondary wheel is opposite the primary wheel at a maximum distance and the rotor is opposite the stator at a minimum axial distance.
