The invention discloses a dual mass flywheel (1) with damping components (8) which is used for a transmission system of a vehicle. The dual mass flywheel is provided with a primary mass flywheel (2) which can rotate around a rotating shaft (11), a secondary mass flywheel (3) which can rotate relative to the primary mass flywheel (2), at least a spiral spring (4) with a spiral turn ring (6) and two ends (7), wherein the spiral spring (4) is configured to be a load when the primary mass flywheel (2) rotates relative to the secondary mass flywheel (3). The damping components (8) are made of a flexible material, and extend between at least two spiral turn rings (6) along an extending direction (a) of the spiral spring (4) in an unload state.
