ABSTRACT:
In a power-transmission unit for variable-speed drive of machinery with hydro-dynamic speed-superposition of a differential gear a second torque converter is provided as a braking device. This increases the effectiveness of the unit by feedback of the superposed output onto the drive side. Particularly advantageous is the use of an oppposed-motion converter as brake converter for certain operating conditions or the combination of a with-motion converter and an opposed-motion converter in the unit. Furthermore, this makes an extension of the speed control range possible.
