ABSTRACT:
Flywheel elements are coupled by a spring arrangement having an intermediate support which is connected resiliently to one flywheel element by long-stroke arcuate helicoidal springs and to the other flywheel element through short-stroke springs. A stop spring device becomes operative between the intermediate support and the one flywheel element in the case of major relative rotations. Additionally or alternatively, a slip coupling which exhibits play may also be arranged. At higher speeds, the long-stroke springs abut bearing surfaces. The friction thereby caused produces a stiffening of the long stroke springs. The mobility of the flywheel elements relative to each other therefore increases with decreasing speed.
