Title:
TORQUE FLUCTUATION SUPPRESSION DEVICE, TORQUE CONVERTER, AND POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2019138421
Kind Code:
A
Abstract:
To smoothly move centrifugal elements with a simple and inexpensive constitution, in a torque fluctuation suppression device having the centrifugal elements and cam mechanisms.SOLUTION: A device includes an inertia ring 20, a plurality of centrifugal elements 21, a plurality of cam mechanisms 22, and a plurality of supporting mechanisms 23. The inertia ring 20 is rotatable with a hub flange 12, and disposed relatively rotatably to the hub flange 12. The centrifugal elements 21 are movable in a radial direction by receiving centrifugal force by rotations of the hub flange 12 and the inertia ring 20. The cam mechanisms 22 convert centrifugal force into circumferential force in a direction to reduce relative displacement, when the relative displacement in a rotating direction occurs between the hub flange 12 and the inertia ring 20. The supporting mechanisms 23 support central portions in a circumferential direction of the plurality of centrifugal elements 21 movably in a radial direction.SELECTED DRAWING: Figure 2
