Field of the Invention The present invention relates to a flywheel device for reducing image capture caused by torque fluctuations of an engine crankshaft in an internal combustion engine, particularly an internal I2 engine for an automobile.

This flywheel has a ring gear for two starting It is fitted and fixed, and is equipped with a clutch mechanism that connects and connects it to the rear (two-speed transmission).The larger the moment of inertia of the flywheel, the smaller the fluctuations in the angular velocity of the crankshaft.

不快な！俸奈動を引き起こすことがあった。Problems to be Solved by Invention However, in conventional flywheel devices, a disk-shaped flywheel is fixedly provided. Since the magnitude of the moment of inertia is limited, torque fluctuations, which become noticeable at low speeds, cannot be sufficiently suppressed. As a result, when the vehicle is running at low speed, the excitation force of the drive system due to the torque fluctuation resonates, causing an unpleasant vibration of several Hz to 10 Hz. It could sometimes cause panic attacks.

しまう。On the other hand, the device described in % Japanese Patent Publication No. 132435/1983 [11] has a configuration in which the engine output is transmitted via the first flywheel and the second flywheel, so it is several tens of hours
Although this method is effective as a countermeasure against so-called in-dish muffled noise at a frequency of about 200 Hz to 200 Hz, it is hardly effective against vehicle body vibrations at around the above-mentioned number H2. In addition, since the first flywheel and the second flywheel are designed to be able to vibrate relative to each other, the elastic members such as intervening coil springs are likely to deteriorate early, and there is a risk of fire resistance. Even if there is a problem (=, that free swing 4#(Unit), on the contrary, it creates a driving range where noise and shooting t# Note get worse.

a flywheel; and an electromagnetic mechanism that switches the first flywheel and the second flywheel into an integrated state or a released state, and when a predetermined vibration occurs (only when the second flywheel is switched between the second flywheel and the first flywheel). It is characterized by having two parts (characterized by two configurations).

となる数Ｈｚ前後の振動が抑制される。If the moment of inertia of the second flywheel is calculated, and the spring constant of the elastic member that supports the second flywheel is k, then the flywheel released from the first flywheel has a number of motions equal to this specific number of motions f. When it receives an excitation force due to torque fluctuation, the second flywheel resonates, and the vibration of the first flywheel is suppressed by the 70 reaction force. Therefore, by appropriately setting the moment of inertia and spring constant k of the wX2 flywheel, vibrations of around several Hz, which become a problem at low speeds, can be suppressed.

制される。On the other hand, when driving at low speeds, if the excitation force of the drive system due to engine torque fluctuation (2) resonates with the vehicle body, causing vehicle body vibration of around several H2 (=, the magnitude of the vibration is greater than a predetermined value). Then, the electromagnet device is turned on based on the detection signal of the imaging sensor 26.This ζ:L rear gusset air 18 is l!
2 flywheels 1691ζ2 are attracted, the 1st flywheel 7 and I! The two flywheels 16 are separated. Therefore, the WJ2 flywheel 16 resonates with its own unique imaging frequency, and conversely, the first flywheel 7 is damped. As a result, the rotation transmitted to the main drive shaft 2 via the clutch mechanism 10 of the first flywheel 7 becomes very smooth, and the above-mentioned unpleasant vibrations of the vehicle body are suppressed.
