  • Patent number: 6569051
    Abstract: An infinite Speed ratio continuously variable transmission comprises a power recirculation mode clutch (9) and direct mode clutch (10). At least one of the power recirculation mode clutch (9) and direct mode clutch (10) comprises an electromagnetic two-way clutch. The electromagnetic two-way clutch maintains the engaged state during excitation and can transmit drive force from both the drive side and non-drive side. On the other hand, when there is a change-over from the energized state to the non-energized state, a one-way clutch state is obtained wherein drive force is permitted only in the transmission direction of drive force in the instant of the change-over to non-excitation. When a drive force is input in the reverse direction to the drive force transmitted in the one-way clutch state, the one-way clutch state is disengaged, and the disengaged state of the clutch is maintained until subsequent re-excitation.
