The utility model discloses a dual-mass flywheel structure which comprises a first-stage mass flywheel, a second-stage mass flywheel assembled in the first-stage mass flywheel and an adapter plate assembled on the second-stage mass flywheel. A pendulum mechanism is arranged on the secondary mass flywheel; the pendulum mechanism comprises a connecting disc and a plurality of pendulum assemblies uniformly distributed on the connecting disc; and the connecting disc is mounted on the secondary mass flywheel. According to the dual-mass flywheel structure disclosed by the utility model, by arrangingthe pendulum mechanism, vibration excitation of an engine at a specific frequency can be attenuated, so that the vibration reduction effect is improved. Meanwhile, the reliability of the pendulum mechanism is improved by additionally arranging the elastic damping element and the sound-proof and dust-proof cover, and noise generated by the pendulum mechanism and the flywheel is reduced. 本实用新型公开了一种双质量飞轮结构，包括一级质量飞轮、装配在所述一级质
