Abstract

A continuously variable transmission (CVT) apparatus adopting a carrier input-ring gear output type. The CVT apparatus includes a transmission control system for changing a torque according to an output load when a first power from an engine is input to generate a second power, a transmission system for generating a transmission output by decelating the number of revolutions of a planetary gear corresponding to a second rotational speed into the number of rotations of the planetary gear in proportion with a difference between the first and second rotational speeds, when the second power is input to a carrier, and a mode selection system for setting the CVT apparatus to one of drive modes.
