Abstract
(EN)
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.

La présente invention a pour but de supprimer un pic de fluctuation de couple sur une plage de vitesse de rotation relativement large dans un dispositif qui permet de supprimer les fluctuations de couple d'un élément rotatif. Pour atteindre ce but, l'invention concerne un dispositif qui est équipé d'un corps de masse (20), d'un élément centrifuge (21), d'un mécanisme (22) à came et d'une pièce de limitation de mouvement. Le corps de masse (20) peut tourner par rapport à un corps rotatif (12) côté sortie. L'élément centrifuge (21) est porté par le corps rotatif (12) côté sortie et peut se déplacer dans la direction radiale. Le mécanisme (22) à came possède une came (31) et un rouleau (30), reçoit une force centrifuge agissant sur l'élément centrifuge (21), et, lorsqu'une différence de phase de rotation est produite entre le corps rotatif (12) côté sortie et le corps de masse (20), convertit la force centrifuge en une force de direction circonférentielle dans la direction qui diminue le déplacement relatif. La pièce de restriction de mouvement possède un orifice (Or) pouvant faire circuler un fluide de travail en fonction du mouvement de l'élément centrifuge (21) dans la direction radiale, et limite la vitesse du mouvement de l'élément centrifuge (21) vers l'intérieur dans la direction radiale.
