  • Patent number: 11255417
    Abstract: A hydrodynamic coupling arrangement has a housing connected to pressure medium lines for conducting pressure medium into or out of a pressure space sealed by a piston of a clutch device relative to a toroidal space of a hydrodynamic circuit provided in the housing. A rotatable area is provided for axially displaceably receiving a radially inner piston hub of the piston of the clutch device, and at least one through-opening which is rotatable relative to the housing is provided in a through-opening area for producing at least one flow connection between at least one pressure medium line and the pressure space. The receiving area and the through-opening area are in rotational communication with a retarding device influencing a flow of pressure medium in the pressure space, this flow of pressure medium arriving in the pressure space after passing through the through-opening area.

A stator (24) is arranged between the turbine and the impeller (22) and is coupled via a stator flange (58) to a freewheel (52) adjoining the driven hub (8) in an axial direction (12). A center of the freewheel (52) is located at a second axial position (54). A difference between the first axial position (53) and the second axial position (54) is greater than a predetermined minimum value.
