Abstract:
A torsional vibration damper includes a plurality of coil springs which are each received in a pair of windows of respective takeoff side and drive side transmission elements. Each spring has a pair of opposed final turns separated by a plurality of intermediate turns, wherein each final turn is against a circumferential boundary of a respective window. Each final turn has a tip area which is in contact with an adjacent intermediate turn, the final turn being separated from the adjacent intermediate turn by a first distance which increases from the tip area to a maximum value within a predetermined angle φ following the tip area. This maximum value, in a load-free state of the springs, is essentially the same as a second distance separating adjacent intermediate turns.
