Abstract
A damper disc assembly comprises an input rotation member, a flanged hub connectable to an output member, an elastic member elastically connecting the input rotation member and the hub flange, a plurality of friction members and an regulator. The plurality of friction members are sandwiched between the input rotation member and the hub flange and develop hysteresis torque when the input rotation member rotates relative to the hub. The regulator enables a select number friction members to be functional depending on whether the damper assembly responds to phases of twisting of the input rotation member relative to the hub flange in either a direction positive or negative with respect to the rotation of the input rotation member.
