Title (EN) PENDULUM DAMPING DEVICE
(FR) DISPOSITIF D'AMORTISSEMENT PENDULAIRE
Abstract:
(EN) A pendulum damping device (1), comprising: - a support (2) able to rotationally move about an axis (X); - at least one pendulum body (3); and - at least one rolling member (11) guiding the movement of the pendulum body (3) relative to the support (2), the rolling member (11) cooperating, on the one hand, with at least one raceway (12) rigidly connected to the support (2) and, on the other hand, with at least one raceway (13) rigidly connected to the pendulum body (3), the rolling member (11) comprising: - a first part (32) defining a first axial end; - a second part (33) defining a second axial end; and - a resilient element (30) disposed in the rolling member (11) so as to axially separate these two parts (32, 33) so that the rolling member (11) exerts an axial clamping force on one of the pendulum bodies (3) and the support (2) when the pendulum body (3) moves relative to the support (2).
(FR) Dispositif (1) d'amortissement pendulaire, comprenant : - un support (2) apte à se déplacer en rotation autour d'un axe (X), - au moins un corps pendulaire (3) et - au moins un organe de roulement (11) guidant le déplacement du corps pendulaire (3) par rapport au support (2), l'organe de roulement (11) coopérant d'une part avec au moins une piste de roulement (12) solidaire du support (2) et d'autre part avec au moins une piste de roulement (13) solidaire du corps pendulaire (3), l'organe de roulement (11) comprenant : - une première partie (32) définissant une première extrémité axiale, - une deuxième partie (33) définissant une deuxième extrémité axiale, et - un élément élastique (30) disposé dans l'organe de roulement (11) de manière à écarter axialement ces deux parties (32, 33) pour que l'organe de roulement (11) exerce une force de serrage axial sur l'un du corps pendulaire (3) et du support (2) pendant le déplacement du corps pendulaire (3) par rapport au support (2).
