Abstract: A hydrodynamic torque converter has a converter housing drivable in rotation by an engine, with an impeller. A turbine non-rotatably connected to an output shaft is hydrodynamically coupled to the impeller by way of a stator through an oil circuit. The turbine is axially slidably supported on the shaft. A friction surface on the turbine upon axial displacement of the turbine comes into frictional contact with a counterpart friction surface on the converter housing, thereby producing a lockup clutch effect. The turbine is also connected by way of springs to a coupling element arranged non-rotatably on the shaft. In an alternative configuration the turbine is arranged non-rotatably on the shaft and the lockup clutch action is by way of friction surfaces on a coupling element and on the converter housing. A torsion damper can be provided between the coupling element and the turbine.

Abstract: An hydraulic servo device for a friction brake in a planetary transmission for motor vehicles contains a cylinder with stepped interior wall, a stationary dividing wall that has a hole and divides the interior of the cylinder into two regions, one piston in each of the two regions formed by the dividing wall, and a hollow piston rod that passes through the hole of the dividing wall and connects the two pistons. The wall of the cylinder has passages, through which a pressure medium enters or exits the cylinder, in each one of the regions formed by the dividing wall. The pistons in each of the regions of the cylinder divides each of the regions into an application-pressure chamber and a release-pressure chamber, forming four chambers in the order of an application-pressure chamber, a release-pressure chamber, an application-pressure chamber, and a release-pressure chamber. The hollow piston rod has openings which allow the pressure medium to enter or exit the piston rod and the application-pressure chambers.
