PROBLEM TO BE SOLVED: To provide a twin planet active drive continuous variable transmission capable of performing quick variable speed operation and continuous variable speed having a high variable speed ratio.SOLUTION: A support frame 1 which supports a planetary gear 3 of one set of planetary gears is mounted on an output side sun gear, a ring gear 2 which has internally-toothed gears right and left is engaged with a parent-child planetary gear and the planetary gear 3, further the planetary gear 3 and the final output side sun gear are engaged with each other and, thereby, two planetary gears are connected with one center shaft. By support frame inputting and a force of variable drive of a ring gear 2 by means of turning and rotation of the parent-child planetary gear via a reciprocal variable driving mechanism of the push gear, a support frame 1 attached to the sun gear engaged with the ring gear 2 is variably driven in the same speed and the same direction one to one relationship as the input and, by performing multiplication from the driving in the same speed and the same direction one to one relationship as the input of final output side sun gear engaged with the ring gear 2 by the rotation drive from the turning drive of the planet gear 3 engaged with the ring gear 2, high continuous variable speed ratio and quick variable speed operation is continuously performed. |
