Patent ID: 6932739

Claim:
A continuosly variable transmission apparatus comprising a toroidal-type continuously variable transmission, a planetary gear mechanism and a clutch device, the clutch device comprising: a low speed clutch connected in order to increase a speed reducing ratio and disconnected in order to decrease the speed reducing ratio; a high speed clutch connected in order to decrease a speed reducing ratio and disconnected in order to increase the speed reducing ratio; and, a controller for switching over the connected and disconnected states of the respective clutches to each other, the controller switching the transmission state of the continuously variable transmission apparatus into any one of a low speed mode and a high speed mode by connecting any one of the clutches, wherein timings for signaling by the controller for switching the connected and disconnected states of the clutches vary according to the switching directions of the low speed and high speed modes; and, a timing for signaling for connecting the low speed clutch with respect to the moment for signaling for cutting off the connection of the high speed clutch in order to switch the high speed mode over to the low speed mode is set earlier than a timing for signaling for connecting the high speed clutch with respect to the moment for signaling for cutting off the connection of the low speed clutch in order to switch the low speed mode over to the high speed mode.
