Abstract

The present invention relates to a hydrodynamic clutch in a drive system, notably a turbo compound system. The hydrodynamic clutch includes a pump impeller and a turbine impeller which together form a toroidal working space. The turbine impeller is joined to a take-off shaft in torsionally fixed fashion and the pump impeller bears, via a bearing arrangement, on the take-off shaft. Coordinated with the toroidal working space is an operating medium supply system. The operating medium supply system includes an operating medium supply space which is arranged radially interior to the toroidal working space and bounded in the axial direction by the bearing arrangement and the contour of the turbine impeller. A central operating medium supply duct is arranged in the take-off shaft and extends in the take-off shaft in the axial direction at least up into the area of the center plane of the clutch. At least one distributing duct connects the central operating medium supply duct to the operating medium supply space.
