Summary:Damping device (1) for a two-weight flywheel of an internal combustion engine comprises a primary part (2) joined to a crankshaft (5), and a secondary part (3) connected indirectly to a gear shaft (7) and arranged together with at least one energy accumulator (4) designed as a flat spiral spring within the primary part. The energy accumulator is arranged in the peripheral direction of the primary part between the primary part and the secondary part. A connecting element (6.2) freely rotating relative to the primary part and secondary part has a form-locking connection (6) with the energy accumulator acting in a radial direction. Preferred Features: Opposite-lying, diametrically and/or offset arranged regions of the energy accumulator are tensioned against each other via the connecting element. Die Erfindung bezieht sich auf eine Vorrichtung zum Kompensieren von Drehstößen oder Drehmomentschwankungen einer Brennkraftmaschine mittels mindestens zweier koaxial zu einer Kurbelwelle der Brennkraftmaschine angeordneter, entgegen der Wirkung einer Dämpfungseinrichtung gegeneinander verstellbar gelagerter Schwungmassen, von denen die eine durch ein an der Kurbelwelle der Brennkraftmaschine angeordnetes Primärteil und die andere durch ein ein Sekundärteil aufweisendes Ausgangsteil eines Getriebes gebildet ist, wobei das Primärteil über einen als Spiralfeder ausgebildeten Kraftspeicher mit dem Sekundärteil elastisch verbunden ist.
