ABSTRACT:
A torsional vibration damper, especially a dual-mass flywheel, has a primary side and a secondary side, which is free to rotate around an axis of rotation relative to the primary side. Starting from a rotation in a direction of rotation around a forward base angle (γ), a forward base spring arrangement exerts a forward base restoring force on the secondary side. Starting from rotation around a forward auxiliary angle (δ), which is greater than the forward base angle (γ), a forward auxiliary spring arrangement exerts an additional forward auxiliary restoring force. Upon rotation around a forward limit angle (ε), both spring arrangements come to a stop together.
