Abstract
The invention relates to a rudder propeller drive comprising a driving motor (1), the output shaft of which can be effectively connected to a shaft of a propeller by means of a drive train. The propeller shaft is accommodated in a rudder propeller housing that can be mounted outside a hull, while the propeller on the propeller shaft is located outside the rudder propeller housing. A lubricating and/or cooling device is provided for the propeller shaft and/or for drive train areas mounted in front of the propeller shaft. The drive train encompasses a hydrodynamic clutch (3) or a hydrodynamic torque converter which is combined with or integrated into the lubricating and/or cooling device in such a way that the hydrodynamic clutch or the hydrodynamic torque converter and the lubricating and/or cooling device use a joint amount of functional fluid.
