Title:
TORQUE FLUCTUATION SUPPRESSION DEVICE, TORQUE CONVERTER, AND MOTIVE FORCE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/016229
Kind Code:
A1
Abstract:
The present invention suppresses a torque fluctuation peak across a wide rotation speed range in a device for suppressing the torque fluctuations of a rotating member. To this end, this device is equipped with an inertia ring (20), a centrifugal element (21), and a cam mechanism (22). The inertia ring (20) is positioned in parallel with an output-side rotating body (12) in the axial direction, and is capable of rotating relative to the output-side rotating body (12). The cam mechanism (22) has a cam (31) and a roller (30), receives the centrifugal force acting on the centrifugal element (21), and when a rotational phase difference is produced between the output-side rotating body (12) and the inertia ring (20), converts the centrifugal force into a circumferential-direction force in a direction which decreases the rotational phase difference. Guide rollers (26a, 26b) are provided on both end sections of the centrifugal element (21). The guide rollers (26a, 26b) sandwich the center of gravity of the centrifugal element (21) therebetween, and contact a projecting section (121) of the output-side rotating body (12) at positions on the opposite side from the contact point between the cam (31) and the roller (30).
