Abstract

In a double-mass flywheel the flywheels of which are coupled with torsional flexibility by at least one set of at least two helical springs (31, 31'), it is proposed that the end spring (31') of the spring set arranged in a channel (29) encircling the axis of rotation (9) of the flywheels in a circular arc is pivoted to control elements (39, 53) of the flywheels via an endshoe (41). For this purpose, the endshoe (41) and the control elements (39, 53) are provided with guide surfaces which have the cross-sectional shape of a circular segment.
