ABSTRACT:
A torsional vibration damper, for installation in the clutch disc of a motor vehicle friction clutch, the damping spring system of which torsional vibration damper comprises at least three spring stages which are sized for different torque ranges of the torque to be transmitted between an input component and an output component. The spring stages are graduated so that they are active in corresponding ranges of the relative angle of rotation between the input component and the output component. The torsional vibration damper comprises a pre-damper which is sized for operation at idle, a low-speed damper which is sized for travel at slow speeds, and a load damper which is sized for load operation. The spring stage of the low-speed damper has an initial torque which is lower than the final torque of the pre-damper, and the load damper also has an initial torque which is lower than the final torque of the low-speed damper. The pre-damper and the low-speed damper are connected to the output part by means of toothings in their disc parts which guide the damper springs so that they are axially movable, but have a rotational play which corresponds to the working range of the dampers. Friction devices corresponding to the individual damper stages can be installed between the individual disc parts.
