Hydrodynamic coupling device used as a hydrodynamic torque converter comprises a housing element having a hollow forming a radial bearing surface and an axial bearing surface for a housing hub

摘要

Hydrodynamic coupling device comprises a housing arrangement (12) containing a turbine wheel (24), which is coupled by a bridging clutch arrangement to the housing arrangement for common rotation about an axis of rotation (A). A housing hub (42) fixed on the inner side (40) of a housing element (14) of the housing arrangement displaceably supports the bridging clutch arrangement in the direction of the axis of rotation. A hollow (60) in the housing element forms a radial bearing surface (66) and an axial bearing surface (68) for the housing hub. Preferred Features: The housing hub is welded to the housing element in the region of the radial bearing surface and/or in the region of the axial bearing surface.
