ABSTRACT:
A hydrodynamic drive and slipping clutch arranged in parallel drive relation to provide a controlled slip input drive to a mechanical gear arrangement. The slip speed of the clutch, and therefore the hydrodynamic drive, is controlled by clutch engagement responsive to differential pressure on the clutch. The differential pressure is maintained by controlling fluid flow through a restriction which has a variable opening responsive to a control element which is movable in response to pressure generated by the speed difference between the hydrodynamic drive input and output to establish clutch engagement of sufficient force to maintain a predetermined slip speed in the hydrodynamic drive.
