  • Torque fluctuation absorbing apparatus
    Patent number: 10781882
    Abstract: A torque fluctuation absorbing apparatus absorbs torque fluctuations occurring in a torque transmission pathway from an input side rotating member to an output side rotating member. The apparatus includes: a vibration absorbing member in which elastic members are coupled in series, and which absorbs torque fluctuations; circular outer contour plates coupled to the input side rotating member, and disposed to be spatially separated from one another in an axial direction of the output side rotating member; a hub member including a boss section coupled to the output side rotating member, and a flange section provided on the boss section and disposed between the outer contour plates; and a circular intermediate plate disposed between the flange section and the outer contour plates, coupled between the elastic members, and transmitting a torque from one elastic member to another elastic member.
