Patent ID: 10487911

Abstract:
A device for inhibiting torque fluctuations includes a mass body disposed in alignment with a rotor in an axial direction. The mass body is rotatable with the rotor, and is also rotatable relatively to the rotor. The device includes a centrifugal element that receives a centrifugal force to be generated by rotation of the rotor and the mass body. A cam mechanism includes a cam and a cam follower. The cam mechanism converts the centrifugal force that acts on the centrifugal element into a circumferential force when a relative displacement is produced between the rotor and the mass body in a rotational direction. The circumferential force is directed to reduce the relative displacement. The cam is provided on the centrifugal element or one of the rotor and the mass body, the cam follower is provided on the one of the rotor and the mass body or the centrifugal element.
