Title:
VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/159831
Kind Code:
A1
Abstract:
A vibration damping device 20 includes: crank members 22 that can oscillate in accordance with the rotation of a driven member 15 to which a torque from an engine EG is transferred; and an inertial mass 23 that is coupled to the driven member 15 via the crank members 22 and that oscillates about a rotation center RC in accordance with the rotation of the driven member 15 and in association with the crank members 22. The vibration damping device 20 is designed such that the effective degree qeff becomes larger as the amplitude of vibration of an input torque transferred from the engine EG to the driven member 15 becomes larger.
