Abstract

A hydrodynamic coupling device having a housing which is, or can be, filled with hydraulic fluid, a turbine wheel which is rotatably arranged in the housing and is, or can be, connected to an output shaft for joint rotation, and a sliding bearing arrangement which the turbine wheel is rotatably mounted relative to the housing, and which has a hydraulic fluid channel arrangement for the passage of hydraulic fluid from radially outside to radially inside relative to the region of the output shaft, or vice versa. It is provided in this case that the sliding bearing arrangement has a sliding bearing element fixed on the turbine wheel, and wherein the sliding bearing element supports the turbine wheel in the axial and radial directions relative to the housing
