Abstract

Abstract A combined fixed ratio planetary traction-drive and toric roller transmission, including a fluid torque converter wherein, in one embodiment, the power input is split at the impeller, with a portion thereof being directed through the planetary drive to overdrive the input race of the toric roller section, thereby reducing torque into the toric section and, consequently, reducing the size requirements of the toric section. The output from the output race is directed to a stator having no overrunning clutch, to rotate the stator in a direction opposite to that of the impeller and turbine. Such external control of the relative speeds of the stator and impeller provides improved converter torquelspeed ratio characteristics. Reaction for the sun member and the roller support is through a nonrotating axial loader mechanism to the casing. A second embodiment utilizes a conventional torque converter stator and overrunning clutch arrangement downstream of the above-described planetary-toric drive, along with the above-described nonrotating axial loader mechanism and means for reducing torque into the toric section.
