Abstract
A generator drive system for the generator (3) of an internal combustion engine (1), including a flexible drive having a traction mechanism (5) which is guided across a generator pulley (6) driving the generator (3). The generator (3) is configured and electrically wired such that the generator (3) can be temporarily driven as a motor, and the generator (3) is coupled to the generator pulley (6) or the crankshaft pulley (7) is coupled to the crankshaft (8) via an overrunning clutch (4) which allows the generator (3), when operated as a motor, running faster than the generator pulley (6) or, taking into consideration a gear ratio, the crankshaft (8).
Claims8
A generator drive system for a generator of an internal combustion engine, the generator drive system comprises a flexible drive comprising a traction mechanism, which is guided via a generator pulley serving to drive the generator, wherein the generator is embodied and electrically switched such that the generator can temporarily be operated as a motor and the generator is coupled to the generator pulley or a motor crankshaft pulley via an overrunning clutch, allowing within the scope of the motor operation the generator runs faster than the generator pulley and/or the crankshaft.
A method for operating a generator connected to an internal combustion engine via a flexible drive and an overrunning clutch system, comprising depending on a motor operating status electrically controlling the generator such that the generator temporarily operates as a motor and accelerating a rotor of the generator such that the generator essentially taps no mechanical acceleration work from the flexible drive.
