Torsional vibration damper, especially a dual-mass flywheel

A torsional vibration damper comprising:

• a primary side;
• a secondary side which is freely rotatable relative to the primary side;
• a forward base spring arrangement which deflects to exert a base restoring force on the secondary side when the secondary side exceeds a forward base angle relative to the primary side in a first direction of rotation;
• and
• a forward auxiliary spring arrangement which deflects to exert a forward auxiliary restoring force on the secondary side when the secondary side exceeds a forward auxiliary angle relative to the primary side in said first direction of rotation;
• wherein said forward auxiliary angle is larger than said forward base angle, and wherein said forward base spring arrangement and said forward auxiliary spring arrangement stop deflecting simultaneously when said secondary side rotates around a forward limit angle relative to said primary side in said first direction of rotation.
