Abstract
(EN) 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.
(FR) Afin de supprimer un pic de fluctuation de couple sur une plage relativement large de vitesses de rotation, la présente invention concerne un dispositif équipé d'un anneau d'inertie (20), de multiples éléments centrifuges (21), de multiples mécanismes de came (22), et de multiples mécanismes de restriction (23). L'anneau d'inertie (20) est capable de tourner conjointement avec une bride de moyeu (12) et est agencé de façon à pouvoir tourner par rapport à la bride de moyeu (12). Les éléments centrifuges (21) sont agencés de façon à recevoir une force centrifuge à partir de la rotation de la bride de moyeu (12) et de la bague d'inertie (20). Les mécanismes de came (22) reçoivent la force centrifuge qui agit sur les éléments centrifuges (21) et, lorsqu'un déplacement relatif dans la direction de rotation se produit entre la bride de moyeu (12) et la bague d'inertie (20), convertissent la force centrifuge en une force de direction circonférentielle dans la direction dans laquelle un déplacement relatif est réduit. Les mécanismes de restriction (23) permettent le fonctionnement des éléments centrifuges (21) au moyen des mécanismes de came (22), et limitent le mouvement des éléments centrifuges (21) dans la direction radiale.
(JA) 比較的広い回転数域においてトルク変動のピークを抑える。この装置は、イナーシャリング(20)と、複数の遠心子(21)と、複数のカム機構(22)と、複数の規制機構(23)と、を備えている。イナーシャリング(20)は、ハブフランジ(12)とともに回転可能であり、かつハブフランジ(12)に対して相対回転自在に配置されている。遠心子(21)は、ハブフランジ(12)及びイナーシャリング(20)の回転による遠心力を受けるように配置されている。カム機構(22)は、遠心子(21)に作用する遠心力を受けて、ハブフランジ(12)とイナーシャリング(20)との間に回転方向における相対変位が生じたときには、遠心力を、相対変位が小さくなる方向の円周方向力に変換する。規制機構(23)は、カム機構(22)による遠心子(21)の作動を許容し、かつ遠心子(21)の径方向の移動を規制する。
