Abstract:
1. A hydrodynamic clutch arrangement comprising: a clutch housing having a drive-side wall for connecting to a drive unit and a takeoff-side wall for connecting to a gearbox; a pump wheel in the housing; a turbine wheel in the housing, the turbine wheel and the pump wheel forming a hydrodynamic circuit in the housing; and a clutch device located inside the housing, the clutch device bringing the housing into and out of working connection with the pump wheel, wherein the clutch device comprises a separating wall having a first side facing the hydrodynamic circuit and a second side facing the takeoff-side wall of the housing, a control chamber between the second side and the takeoff-side wall, and a first control line connected to a pressure supply system, wherein the hydrodynamic circuit has a prevailing pressure and the pressure supply system selectively supplies the control chamber with a control pressure which is essentially the same as the prevailing pressure.
