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.
Claims7
A device for varying an equivalent inertia moment of a flywheel disposed between an engine and a transmission, comprising:
- a flywheel mounted for varying rotational speed with respect to the rotational speed of a crankshaft of the engine;
- a manual transmission selectively coupled to said flywheel and including an input shaft and an output shaft;
- a ring gear coupled to said flywheel so as to rotate at the same rotational speed as the rotational speed of the flywheel;
- a sun gear coupled to said output shaft of said transmission so as to rotate at the same rotational speed as the rotational speed of the output shaft of the transmission;
- a planet carrier coupled to a crankshaft so as to rotate at the same rotational speed as the rotational speed of the crankshaft;
- and
- a pinion rotatably carried by the planet carrier, said pinion engaging with said ring gear and said sun gear.
