Abstract

In some embodiments, a torque damper apparatus can achieve reduced stiffness as well as sufficient vibration absorbing property while increasing the dampening ratio of the torque variation. In some embodiments, a torque damper apparatus comprises an input member to which an engine torque is inputted; damper springs able to absorb variation of torque inputted from the input member; and/or a driving power of the engine configured to be transmitted to an output shaft of a vehicle via the input member and the damper springs. The damper springs can comprise a plurality of coil springs arranged along the circumference of the input member. The torque damper apparatus can further comprise a plurality of separate members interposed between the damper springs and configured to be independently rotated with respect to each other when the engine torque is transmitted thereto.
