Abstract

Un mécanisme d'amortissement (10) de fluctuations de couple, comporte un premier organe tournant (12), un deuxième organe tournant (18) oscillant par rapport au premier organe tournant (12) de part et d'autre d'une position médiane, des ressorts à boudin (20) disposés entre le premier organe tournant (12) et le deuxième organe tournant (18) et un anneau de rétention flottant (22) disposé radialement à l'extérieur des ressorts à boudin (20) et apte à tourner librement par rapport au premier organe tournant (12) et par rapport au deuxième organe tournant (18) et à confiner radialement les ressorts à boudin (20). Chaque ressort à boudin (20) présente une portion médiane cintrée (40) comportant au moins une spire en appui radial contre l'anneau de rétention (22), et deux portions intermédiaires (42, 44) situées chacune entre l'une des deux portions d'extrémité (34, 36) et la portion médiane cintrée (40) et comportant chacune plusieurs spires qui, en position médiane et au moins en deçà d'une vitesse prédéterminée, sont sans contact avec l'anneau de rétention (22).A torque fluctuation damping mechanism (10) comprises a first rotating member (12), a second rotating member (18) oscillating relative to the first rotating member (12) on either side of a middle position , coil springs (20) disposed between the first rotating member (12) and the second rotating member (18) and a floating retention ring (22) disposed radially outside the coil springs (20) and adapted to rotate freely relative to the first rotating member (12) and relative to the second rotating member (18) and to radially confine the coil springs (20). Each coil spring (20) has a curved middle portion (40) comprising at least one turn in radial support against the retention ring (22), and two intermediate portions (42, 44) each located between one of the two end portions (34, 36) and the curved middle portion (40) and each comprising several turns which, in the middle position and at least below a predetermined speed, are without contact with the retention ring (22) .
