Abstract:
A damper disc assembly includes an input plate, an output unit including an input-side member and an output-side member, a high stiffness damper unit, a low stiffness damper unit and first and second hysteresis torque generating mechanisms. The low stiffness damper unit is disposed axially between the input plate and the input-side member, and is actuated in a low torsion angular range of torsional characteristics. The first hysteresis torque generating mechanism generates a first hysteresis torque in a lower torsion angular part of an actuation range of the low stiffness damper unit. The second hysteresis torque generating mechanism generates a second hysteresis torque in a higher torsion angular part of the actuation range of the low stiffness damper unit and an actuation range of the high stiffness damper unit.
