<p>The helical spring (1) comprises a spring wire having number of windings (5a,5b). The final-side winding regions (2a,2b) of the spring wire are cooperated with each other and are provided with helical spring systems (3a,3b). The helical spring system (3a) is moved along axial direction to a central line in relation to the helical spring system (3b). An attenuation device is provided to attenuate resonant vibration of helical spring. A damping element (4) is arranged in middle area of the attenuation device and is arranged between adjacent windings.</p> |
