ABSTRACT:
A hydraulically operated continuously variable transmission includes a fixed shaft mounted in a transmission case, an output shaft rotatably supported in the transmission case, and a hydraulic motor coupled to the output shaft and having a motor cylinder and an annular array of slidable motor plungers disposed around an axis of rotation thereof and slidably disposed in respective cylinder holes defined in the motor cylinder. The hydraulic motor also has a distribution ring supported on the fixed shaft and rotatable relatively to and slidable against an end face of the motor cylinder for introducing high-pressure oil successively into the cylinder holes and discharging oil successively from the cylinder holes in response to rotation of the motor cylinder. The transmission further includes an input shaft rotatably supported in the transmission case, a hydraulic pump coupled to the input shaft, at least one of the hydraulic pump and the hydraulic motor being of the variable-displacement type, a closed hydraulic circuit interconnecting the hydraulic pump and the hydraulic motor, and a spring disposed around the fixed shaft for normally urging the distribution ring resiliently against the end face of the motor cylinder.
