Title (EN) FRICTION DEVICE FOR CLUTCH
(FR) DISPOSITIF DE FROTTEMENT POUR EMBRAYAGE
Abstract:
(EN) The invention relates to a clutch device provided with a torsion assembly comprising a load spring washer and a friction ring (16, 17) resiliently deformable about an axis and mounted on a central torque-transmission member (7) so as to prestress at least one drive surface (28).
(FR) Disque d'embrayage muni d'un dispositif d'amortissement de torsion comportant une rondelle élastique de charge et une rondelle de frottement (16, 17) élastiquement déformable autour d'un axe et montée sur un organe central de transmission de couple (7) de sorte à exercer une précontrainte sur au moins une surface d'entraînement (28).
