Abstract
A bridge coupling on a hydrodynamic converter comprises a piston deflectable in the axial direction and connectable via at least one friction lining to the converter housing. A cavity is provided in the friction lining for the passage of hydraulic fluid from the converter's hydraulic fluid circuit. The cavity, in a transition area to the friction surface of the friction lining includes a stamped region to create an edge-free transition.
