Title:
遠心振り子式ダンパ装置
Document Type and Number:
Japanese Patent JP7091769
Kind Code:
B2
Abstract:
To reduce a torque variation of a rotary member while positively restricting occurrence of allophone at the time of slow rotation of the rotary member at a centrifugal pendulum type damper device in which a pendulum is oscillatably supported at the rotary member.SOLUTION: An oscillation regulation mechanism 60 of a centrifugal pendulum type damper device 30 is constituted in such a way that it comprises a weight 61 and an energization member 62 for energizing the weight 61 inside in a radial direction that are arranged at a groove part of a rotary member side, a groove part 53 of a pendulum side, the groove part of the rotary member side and the groove part 53 of the pendulum. When its speed is less than a predetermined rotating speed, the weight 61 is arranged inside in a radial direction to restrict oscillation of a pendulum 51 and when its speed is higher than the predetermined rotating speed, the weight 61 is arranged outside in a radial direction against a biasing force of the energization member 62 by a centrifugal force to release oscillation restriction of the pendulum 51.SELECTED DRAWING: Figure 2
