Beschreibung
Zusammenfassung:	A belt-and-pulley type continuously variable transmission comprises a drive pulley mounted on an input shaft and comprising a stationary conical member and a movable conical member, a driven pulley mounted on an output shaft and comprising a stationary conical member and a movable conical member, and a V-belt trained around the drive and driven pulleys. The movable conical members are axially movable to vary the effective diameters of the drive and driven pulleys for controlling the speed ratio. The movable conical members are disposed on one side and the other side of the V-belt, respectively. The transmission further includes a main servomechanism which is operatively coupled to the movable conical members for controlling axial movement of the movable conical members. According to another embodiment, a belt-and-pulley type continuously variable transmission comprises a drive pulley mounted on an input shaft and comprising a stationary conical member and a movable conical member, a driven pulley mounted on an output shaft and comprising a stationary conical member and a movable conical member, a V-belt trained around the drive and driven pulleys, and first and second servo hydraulic pressure chambers for axially moving the movable conical members to vary the effective diameters of the drive and driven pulleys for controlling the speed ratio. The transmission further includes a first servomechanism for producing a prescribed output of displacement in a prescribed direction based on a prescribed signal, and a second servomechanism operatively connected to the first servomechanism and one of the drive and driven pulleys for transferring the prescribed output of displacement produced by the first servomechanism to said one pulley.
