Abstract
A planetary variator applicable in a variable transmission for realizing a variable speed and torque ratio includes: a ring wheel; at least two planet wheels, the at least two planet wheels including a shaft portion and a wheel portion that is rotatable about the shaft portion, the shaft portion having a longitudinal central axis, the longitudinal central axis also being the rotation axis of the wheel portion, each planet wheel being freely rotatable about a hinge axis that is oriented essentially perpendicularly with respect to a plane defined by the common central axis and the rotation axis of the wheel portion of the planet wheel; and a sun wheel. The ring wheel and the sun wheel are axisymmetric bodies positioned with respect to a common central symmetry axis. Interaction between the ring wheel, the at least two planet wheels, and the sun wheel takes place through a rolling motion.
