た。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an impact torque absorber that can absorb impact caused by sudden torque fluctuations without sacrificing efficiency. - Sudden torque fluctuations due to OFF or clutch engagement may impact mechanical parts and cause damage.
In order to avoid impairing ride comfort or producing scratching noise, it is possible to provide clutch discs with torsional characteristics with hysteresis, or to install fluid couplings in the middle of the power train to absorb impact torque. It has become widespread.

という問題点を有する。However, in the former case where the clutch disc has a torsional characteristic with hysteresis, the hysteresis is set according to the size of the impact torque in question, so it is not possible to absorb all sizes of impact torque. The problem is that it cannot be done. Unfortunately, the latter fluid coupling has the problem that slip occurs between the two shafts connected to the fluid coupling, impairing driving force transmission efficiency and deteriorating fuel efficiency.
