摘要： The invention relates to an automatically and continuously variable transmission for changing the velocity of a driven shaft relative to the velocity of a drive shaft. The transmission includes three epicyclic trains, namely an input train, a control train and an intermediate train. The input train includes an element driven by the drive shaft and another element connected to the driven shaft. The control train is a high ratio train including a planetary gear system, the planet-carrier of which is driven by an electric motor of variable velocity and low power, of the order of 1 percent of the power to be transmitted from the drive shaft to the driven shaft. A first sun-wheel of the planetary gear system is connected to the third element of the input train and a second-sun-wheel is connected to an element of the intermediate train, the two remaining elements of which are respectively connected to the input train and to either of the drive or the driven shafts. The control motor provides a constant reaction torque and consists of a double squirrel-cage, asynchronous electric motor, the stator of which is supplied by an alternator driven by the transmission so as to produce a field rotating permanently in the same direction. The control motor is so constructed as to have a torque of between 1 percent and 3 percent of the maximum transmitted torque, the ratio of the epicyclic train which drives it being selected accordingly.
