Patent ID: 10508708

Abstract:
A torque fluctuation inhibiting device is disclosed. The device includes a mass body, centrifugal elements, guide members, and cam mechanisms. The mass body is rotatable in accordance with and relative to the rotor. The centrifugal elements are radially movable, and disposed to receive a centrifugal force by the rotor and the mass body. The guide members are provided on circumferential ends of each centrifugal element, and guide movement of each centrifugal element while supported by one of the rotor and the mass body. The cam mechanisms convert the centrifugal force into a circumferential force when a relative displacement occurs between the rotor and the mass body while the centrifugal force acts on each centrifugal element. The cam mechanisms each include a cam provided on the other of the rotor and the mass body, and a cam follower disposed on a straight line connecting the guide members in each centrifugal element.
