Beschreibung
Zusammenfassung:	A continuously variable hydrostatic transmission includes an input shaft connected to drive a hydraulic pump unit, a grounded hydraulic motor unit, and an output shaft. A wedge-shaped swashplate is pivotally mounted to the output shaft in driving connection to receive output torque resulting from the exchange of pressurized hydraulic fluid between the pump and motor units through specially configured ports in the swashplate. A hydraulically actuated ratio controller shifts the axial positions of spherical bearings mounting a pump cylinder block in the hydraulic pump unit and a motor cylinder block in the hydraulic motor unit to adjust the swashplate angle relative to the output shaft axis and thereby change transmission ratio.
