ABSTRACT:
A driving device includes a power supply unit and a torque converter. The power supply unit outputs a constant power. The torque converter has a gear train that is connected to the power supply unit and interconnects a flywheel and an input shaft in order to respectively transmit a first part and a second part of the power to the flywheel and the input shaft. The input and output shafts have respectively first and second variable-diameter pulleys on which a belt member is trained. The effective diameters of the first and second pulleys are automatically varied in response to the torque exerted on the input and output shafts to maintain the rotational speed of the output shaft at a constant level while the flywheel compensates for power variation of the output shaft without changing the power of the power supply unit.
