Title:
TORQUE FLUCTUATION SUPPRESSION DEVICE, TORQUE CONVERTER, AND POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/150777
Kind Code:
A1
Abstract:
In order to suppress a torque fluctuation peak across a comparatively wide range of rotation speed, this device is equipped with an inertia ring (20), multiple centrifugal elements (21), multiple cam mechanisms (22), and multiple restriction mechanisms (23). The inertia ring (20) is capable of rotating together with a hub flange (12), and is arranged so as to be capable of rotating relative to the hub flange (12). The centrifugal elements (21) are arranged so as to receive centrifugal force from the rotation of the hub flange (12) and the inertia ring (20). The cam mechanisms (22) receive the centrifugal force acting on the centrifugal elements (21) and, when relative displacement in the rotation direction occurs between the hub flange (12) and the inertia ring (20), convert the centrifugal force to a circumferential-direction force in the direction in which relative displacement is reduced. The restriction mechanisms (23) allow operation of the centrifugal elements (21) by means of the cam mechanisms (22), and restrict movement of the centrifugal elements (21) in the radial direction.
