Abstract
The flywheel elements are resiliently coupled by means of two groups of springs which are connected in parallel. One group of springs operates with play and becomes operative substantially only when high torques are transmitted. At low speeds when only low torques can be generated by the engine, the flywheel has a very low resonance frequency determined solely by the second group of springs without play. This frequency remains below the frequencies of the vibrations which occur in this service phase. Upon the transmission of higher torques generated by the engine at higher speeds, although the resonance frequency rises due to the effect of the first group of springs with play, nevertheless, the resonance frequency remains below the frequency of the vibrations which occur at higher speed.
