Improvements in automatic transmission systems with application in electric automobile motors for the use of children. The invention comprises a pulley composed of two symmetrical halves (1) and (2), in which the bringing together of the planes of both halves varies the diameters of actuation of the transmission belt (13) and thus the speed-power ratio. The moving half (2) rests by gravity on free bodies (12) which are moved towards the periphery of an enclosure (9) containing them, by the effect of centrifugal force, ascending along ramps (11), and bringing the moving half (2) towards the fixed half (1). A second receptor pulley (14), comprising two halves, moving and fixed, linked flexibly by a spring (16), which compensates the traction force of the belt (13).
