Abstract
A damper disc assembly includes first and second input plates, an output unit, a high stiffness damper unit, and first and second low stiffness damper units. The output unit includes an input-side member and an output-side member disposed rotatably relative to each other. The high stiffness damper unit elastically couples the input-side member and the first and second input plates in a rotational direction and is actuated in a high torsion angular range of torsional characteristics. The first and second low stiffness damper units elastically couple the input-side member and the output-side member and are actuated in a low torsion angular range of the torsional characteristics. The second low stiffness damper unit is actuated later than actuation of the first low stiffness damper unit.
