Title (EN) TORSIONAL DAMPER WITH BLADE
(FR) AMORTISSEUR DE TORSION A LAME
Abstract:
(EN) The invention relates to a torsional damper for a torque-transmission device, which comprises: a first element (1) and a second element (2) which are rotatable relative to one another; and a first damping means and a second damping means, each damping means comprising a resiliently deformable blade (9) comprising an attachment portion (12) and a resilient portion (13), a bearing element supported by the other one of said first and second elements and arranged, for an angular displacement between the first and second elements relative to an inoperative angular position, such as to exert a bending force on the blade, said damper being characterised in that the circumference of the resilient portion of the blade of the first damping means increases beyond the attachment portion of the blade of the second damping means.
(FR) Amortisseur de torsion pour dispositif de transmission de couple comportant : un premier élément (1) et un second élément (2) mobiles en rotation l'un par rapport à l'autre; et un premier moyen d'amortissement et un second moyen d'amortissement, chaque moyen d'amortissement comportant une lame élastiquement déformable (9) comportant une portion de fixation (12) et une portion élastique (13), un élément d'appui porté par l'autre desdits premier et second éléments et agencé pour, pour un débattement angulaire entre les premier et second éléments par rapport à une position angulaire de repos, exercer un effort de flexion sur la lame, ledit amortisseur étant caractérisé en ce que la portion élastique de la lame du premier moyen d'amortissement se développe circonférentiellement au-delà de la portion de fixation de la lame du second moyen d'amortissement.
