FLY WHEEL FOR VEHICLE

摘要

PURPOSE: A flywheel in a vehicle is provided to efficiently absolve twist vibration generated in an engine and to ensure comfortable travelling feeling. CONSTITUTION: A fly wheel comprises a first mass(10) forming first and second semi oval guide holes(11,12) by being mounted on a driving shaft of an engine; first and second springs(13,14) inserted to the first and second semi oval guide holes; a second mass(15) installing a rotation plate(16) by being established on an input shaft of a transmission; first and second damping force generating blocks(17,18) pressurizing the first and second spring by being movably installed through guide bars on an upper side and a lower side of the rotation plate; and third/forth springs(21,22) elastically biasing the first and second damping force generating blocks outside. The first and second semi oval guide holes are larger toward outside on a vertical middle line on an inside face. The first and second springs are pressurized to apply power toward a rotation direction of the first and second damping force generating blocks. Then, the rotation plate is rotated to revolute the second mass.
