Abstract

A continuously variable transmission (CVT apparatus adopting a sun gar input-carrier output type. The CVT apparatus includes a torque converter for changing a rotational force and a rotational speed transmitted to a turbine according to a load to generate a second power; a transmission system for generating a transmission output by decelerating the number of revolutions of planetary gears generated in correspondence to a second rotational speed into the number of rotations of planetary gears in proportion with a rotational speed difference, for a carrier supporting the planetary gears, in the case that the rotational speed difference between first and second rotational speeds is generated; and a mode selection system for setting the CVT apparatus to one of drive modes.
