Title:
TORQUE FLUCTUATION SUPPRESSION DEVICE, TORQUE CONVERTER, AND MOTIVE FORCE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/016212
Kind Code:
A1
Abstract:
The present invention suppresses a torque fluctuation peak across a comparatively wide rotation speed range in a device for suppressing the torque fluctuations of a rotating member. To this end, this device is equipped with a body of mass (20), a centrifugal element (21), a cam mechanism (22), and a movement restriction part. The body of mass (20) is capable of rotating relative to an output-side rotating body (12). The centrifugal element (21) is supported by the output-side rotating body (12), and is capable of moving in the radial direction. The cam mechanism (22) has a cam (31) and a roller (30), receives a 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 body of mass (20), converts the centrifugal force into a circumferential-direction force in the direction which decreases relative displacement. The movement restriction part has an orifice (Or) capable of circulating a working fluid according to the movement of the centrifugal element (21) in the radial direction, and restricts the speed of the movement of the centrifugal element (21) toward the inside in the radial direction.
