Abstract

The invention relates to torsion vibration dampers in the power transmission path of a motor vehicle with an internal combustion engine, the coil thrust springs used being particularly in the case of a considerable length in proportion to their diameter, already precurved prior to fitment into their final position. This facilitates fitment and makes it possible to influence the development of friction force as the rotary speed increases.
