Abstract
A supplemental hydraulic motor is provided that is coupled to an output of a continuously variable transmission in order to increase transmission output torque. The supplemental hydraulic motor is powered by a hydraulic steering pump and is also operational as a ground-driven, secondary hydraulic steering pump. In addition, the supplemental hydraulic motor may be used to retard the transmission.
