Abstract

The present invention relates to a continuously variable transmission that transmits power generated in an engine to a driving means without a step. The primary transmission mechanism (4) includes a variable drive pulley (1), a variable driven pulley (2), and a belt (3). And a shift control mechanism 9 connected to the shift mechanism 4 to achieve a final shift, wherein the shift control mechanism 9 includes one planetary gear unit 5 and two clutches C1. , C2), the planetary gear unit 5 is provided on the driven shaft 12 of the variable driven poly (5) to drive together with the driven shaft 12, the planetary gear unit (5) The first clutch C1 and the second clutch C2 are connected in parallel to the pinion gear 15 of the pinion gear 15, and the first clutch C1 transmits rotational force from the high speed gear 6 of the input shaft 11. The second clutch C2 has a structure connected to the driven shaft 12 while being connected to the receiving direct gear 7. The continuously variable transmission of the present invention can be compact in structure, and the rotational force of the input shaft 11 is transmitted to the planetary gear unit 5 of the shift control mechanism 9, thereby increasing the limit of power transmission capacity. Can overcome the limitations of the shift range.
