Abstract
A device for varying an equivalent inertia moment of a flywheel comprises a flywheel, a manual transmission including an input shaft and an output shaft, a ring gear coupled to the flywheel, a sun gear coupled to the output shaft and a pinion engaging with the ring gear and the sun gear. A planetary gear mechanism consisting of the ring gear, the sun gear and the pinion increases the equivalent inertia moment of the flywheel during idling, at low speeds and decreases same during normal running, thereby suppressing vibration and noise during idling and improving response during normal running.
