Abstract
A continuously variable power transmission has a fixed mounting plinth, by which the transmission is mounted to a fixed structure, and an output shaft, to which an output device can be connected. A pintle having a flat radial slab and an axial arbor supports a radial piston pump rotor an one end of the arbor and a radial piston motor rotor on the other end of the arbor. A driven pulley surrounds the transmission and constitutes its exterior shell within which working fluid is contained. The pulley is coupled to a ring gear of a planetary gear set having a planet carrier with planet gears engaged between the ring gear and a sun gear. The sun gear is coupled to and drives the pump rotor, and the carrier is coupled to the output shaft. Working fluid pressurized by the pump is conveyed to the motor rotor to generate torque in the motor which is carried back to the planet carrier.
