More Information
Summary:A torque fluctuation reducing apparatus (3) includes a first main damper (3a) provided on a power transmission path between a drive source (1) and a transmission (7), and reducing fluctuation torque generated between the drive source and the transmission, a second main damper (3b) provided at a transmission-side relative to the first main damper to be in series with the first main damper and reducing the fluctuation torque, the second main damper including a vibration damping property which is different from a vibration damping property of the first main damper, a dynamic damper (3c, 3d) provided between the first main damper and the second main damper, and restricting vibration at a specific resonance point of a drive system on the power transmission path by using an inertia body (34d, 35, 45c) and an elastic force, a chamber (53) accommodating the first and the second main dampers, and the dynamic damper, and a viscous medium (54) enclosed in part of the chamber.
