Abstract

A driven mechanical transmission system is disclosed. The system includes an output shaft and an electrical motor, with a first rotor and a second rotor counter rotatable relatively to the first rotor. The system further includes a transmission having a first portion adapted to convey a rotational torque from the first rotor to the output shaft and a second portion adapted to convey a rotational torque from said second rotor to said output shaft in a reversed direction, relatively to the first portion. The system further includes a means of controllably preventing a rotation of the first rotor and a unidirectional bearing, disposed in between the first rotor and the output shaft. Upon controllably preventing rotation of the first rotor, the output shaft is rotatable in high gearing ratio; whereas upon allowing rotation of both the first and second rotors, the output shaft is rotatable in low gearing ratio.
