ABSTRACT:
The invention provides a continuously variable transmission which is compact and high in operation efficiency, and allows smooth starting and smooth change-over between forward running and backward running. The continuously variable transmission includes a torque converter which in turn includes at least three runners of an impeller, a first turbine and a second turbine. The continuously variable transmission further includes a lock-up clutch operable to couple the impeller and the first turbine to each other, and a hydraulic brake disposed on a first turbine shaft connected to the first turbine and capable of being fixed to a housing. The second turbine is connected to a second turbine shaft connected to a pulley of a transmission via a one-way clutch which transmits a force only when the second turbine rotates in a direction reversed to the direction of rotation of the impeller. The continuously variable transmission further includes a hydraulic clutch operable to couple the first turbine shaft and the second turbine shaft to each other.
