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

A hydrodynamic torque converter is embodied with a converter housing that, on its side facing a drive, has a substantially radially-running primary flange. Attached to the primary flange are a central pin for mounting and a holder for holding the converter housing on the drive, as well as a housing hub for mounting a transmission shaft of an output. At least one of the connecting elements on the primary flange (i.e., the holder, the housing hub and the central pin) is connected to the primary flange by an outward pressing. The holder, housing hub and central pin respectively establish a connection between the primary flange and the drive or output. This connection to the primary flange is created by material displacement into an opening in the connecting element in question, which opening is located on the side facing away from the connection. A rear-gripping device that grips behind the rear side of the connecting element is created at the free end of the outward pressing by means of material compression in the opposite direction and serves as to axially secure the connection of the respective components to each other.

A hydrodynamic torque converter a hydrodynamic circuit has at least a pump impeller and a turbine wheel. The turbine wheel has a turbine shell with a blading and a turbine hub which is in rotary connection with an output shaft. The turbine shell extends radially inward between an extension region of axial abutments and is provided with stiffeners.

A housing component for a hydrodynamic clutch device, especially a hydrodynamic torque converter, possesses a friction surface region for a converter lock-up clutch of the clutch device on a first side which is positionable for facing the interior of the clutch device. This housing component is formed by, at least in the region of the friction surface region, the reshaping of a metal component. On a second side of the housing component lying opposite to the first side a surface structuring is formed in a region corresponding to the friction surface region by reshaping of the metal component to form the friction surface region.
