Abstract

La présente invention concerne un amortisseur de torsion (1) comprenant: - un élément primaire (3), - un élément secondaire (7), l'élément primaire (3) et l'élément secondaire (7) étant mobiles en rotation l'un par rapport à l'autre autour d'un axe de rotation (X), - un moyen d'amortissement élastique (11) configuré pour amortir les acyclismes de rotation entre l'élément primaire (3) et l'élément secondaire (7), - un voile (9) couplé en rotation à l'élément secondaire (7) et destiné à venir en contact avec le moyen d'amortissement élastique (11), le voile (9) étant fixé à l'élément secondaire (7) par au moins un rivet (12) situé à un rayon prédéfini (R) de l'axe de rotation (X), - un premier dispositif d'étanchéité (15, 16) destiné à être centré sur l'axe de rotation (X), fixée par le au moins un rivet (12) et s'étendant dans une direction en éloignement de l'axe de rotation (X), le premier dispositif d'étanchéité (15, 16) comprenant une partie extrémale (15b, 16b) destinée à venir en contact avec l'élément primaire (3) ou un élément fixé sur l'élément primaire (3) et, - un deuxième dispositif d'étanchéité (17, 16) destiné à être centré sur l'axe de rotation (X), fixée par le au moins un rivet (12) et s'étendant dans une direction orientée vers l'axe de rotation (X) de l'amortisseur de torsion (1), le deuxième dispositif d'étanchéité (17, 16) comprenant une partie extrémale (17b, 16b') destinée à venir en contact avec l'élément primaire (3) ou un élément fixé sur l'élément primaire (3)..The present invention relates to a torsion damper (1) comprising: - a primary element (3), - a secondary element (7), the primary element (3) and the secondary element (7) being rotatable one with respect to the other about an axis of rotation (X), - an elastic damping means (11) configured to dampen the acyclisms of rotation between the primary element (3) and the secondary element (7 ), - a web (9) coupled in rotation to the secondary element (7) and intended to come into contact with the elastic damping means (11), the web (9) being fixed to the secondary element (7 ) by at least one rivet (12) situated at a predefined radius (R) from the axis of rotation (X), - a first sealing device (15, 16) intended to be centered on the axis of rotation ( X), fixed by the at least one rivet (12) and extending in a direction away from the axis of rotation (X), the first sealing device (15, 16) comprising an end portion (15b, 16b) intended for coming into contact with the primary element (3) or an element fixed to the primary element (3) and, - a second sealing device (17, 16) intended to be centered on the axis of rotation (X) , fixed by the at least one rivet (12) and extending in a direction oriented towards the axis of rotation (X) of the torsion damper (1), the second sealing device (17, 16) comprising an end portion (17b, 16b ') intended to come into contact with the primary element (3) or an element fixed to the primary element (3).
