Abstract

A hydrodynamic clutch device, particularly a hydrodynamic torque converter or fluid coupling, comprises a housing arrangement, a turbine wheel which is arranged in the housing arrangement so as to be rotatable with respect to the housing arrangement about an axis of rotation, a lockup clutch arrangement by means of which a torque-transmitting connection can be selectively produced between the housing arrangement and the turbine wheel, wherein the lockup clutch arrangement comprises a clutch element which is connected by a connection arrangement to the housing arrangement so as to be substantially fixed with respect to rotation but axially displaceable relative to it, wherein the connection arrangement comprises at least one elastically deformable connection element which is fixedly connected with the housing arrangement on the one hand and with the clutch element on the other hand. It is provided that the at least one connection element is connected with the housing arrangement in an area between surfaces of a housing element and of a housing huh element which is fixedly connected with the housing element, wherein these surfaces face one another.
