Patent ID: 7077777

Claim:
A continuously variable transmission comprising: an input shaft rotatively driven by a drive source; an output shaft for taking out power based on the rotation of said input shaft; a toroidal type continuously variable transmission; a planetary gear mechanism including: a sun gear; a ring gear disposed around said sun gear; and a planetary gear provided between said sun gear and said ring gear, wherein two transmission paths are provided for transmitting the power from said drive source to said output shaft, and wherein the power transmitted to first and second power transmission paths is made to converge to two gears of said sun gear, said ring gear, and said planetary gear, and a remaining gear other than said two gears is coupled with said output shaft; and a mode changeover device effecting a changeover between, during forward movement, a first mode for a low speed side and a second mode for a high speed side, the changeover between the first and second modes being effected by the operation of connecting and disconnecting a first mode clutch and a second mode clutch, wherein said mode changeover device controls varying a time over which said changeover occurs, wherein the first mode clutch and the second mode clutch are wet clutches, and wherein the operation of effecting the changeover between the first mode and the second mode is effected in 0.2 to 1 second.
