Abstract:
1. A belt-drive system driven by an internal combustion engine mounted on an automotive vehicle, the belt-drive system comprising: a driving pulley connected to a crankshaft of the internal combustion engine; a plurality of driven pulleys connected to respective on-board devices; a belt wound around the driving pulley and the plurality of the driven pulleys so that all the driven pulleys are driven by the driving pulley, wherein: the plurality of the driven pulleys include a pulley of an automatic belt-tensioner that controls a belt tension and pulleys of a first generator and a second generator, an inertia moment of the first generator being larger than an inertia moment of the second generator; the pulley of the first generator includes a one-way clutch that transmits rotational torque in one direction from the crankshaft pulley to a rotor of the first generator; the pulley of the second generator is a solid pulley that transmits rotational torque in both directions between the crankshaft pulley and a rotor of the second generator; and the pulley of the first generator is coupled to the belt at a position closer to the pulley of the belt-tensioner than the pulley of the second generator.
