Abstract

In a hydrodynamic clutch with a lockup clutch, a hydraulic fluid is in operative connection with a piston space outside of a driven shaft constructed as a hollow shaft by means of a plurality of fluid channels. The piston space adjoins an actuation piston by means of which the lockup clutch can be actuated. The fluid channels extend substantially axially in a partial portion. In the partial portion, the fluid channels are surrounded on the radial inside by the driven shaft and are surrounded on the radial outer side and in circumferential direction by a hub part.
