ABSTRACT:
An infinitely variable hydrostatic transmission includes an input shaft connected to drive a hydraulic pump unit, a grounded hydraulic motor unit, and an output shaft. A swashplate assembly is connected to impart output torque to the output shaft resulting from the pumped exchanges of pressured hydraulic fluid between the hydraulic pump and motor units. A ratio controller is linked to independently, variably position input and output members of the swashplate assembly and thus vary nutating magnitudes of cylinder blocks of the hydraulic pump and motor units, pursuant to adjustably setting ratio conditions of the transmission.
