ABSTRACT:
A friction mechanism in a damper disc has a cylindrical hub adapted to connect to an output device and having a radial flange. A pair of side plates are connected to an input member and disposed at respective sides of the flange. A sub-plate is disposed between the side plate and the flange. A torsion spring twistably connects the flange and the side plates together. The mechanism includes a first friction device for a first torsion operation; and a second friction device for a second torsion operation. The sub-plates are adapted to torsionally turn with respect to one of the flange and the side plates in a first torsion operation and to torsionally turn with respect to the other of the flange and the side plates in a second torsion operation. The first and second friction devices are radially shifted to each other and are disposed independently of each other.
