ABSTRACT:
A hydrostatically operated continuously variable transmission has a hydraulic pump and a hydraulic motor which are interconnected by a closed hydraulic circuit. The hydraulic pump comprises a plurality of pump plungers reciprocably disposed radially in a cylinder block, and an eccentric pump ring engaging outer ends of the pump plungers and supported eccentrically with respect to the center of rotation of a cylinder block for imparting reciprocating movement to the pump plungers in response to rotation of the cylinder block. The hydraulic motor comprises a plurality of motor plungers reciprocably disposed radially in the cylinder block, and an eccentric motor ring engaging outer ends of the motor plungers and supported eccentrically with respect to the center of rotation of the cylinder block for imparting reciprocating movement to the motor plungers in response to relative rotation between the cylinder block and an output shaft. At least one of the eccentric rings is supported in a manner for being eccentrically displaced from the center of rotation of the cylinder block by a variable amount of eccentricity.
