Pendulum-oscillator-type damping system comprising an improved guiding device

摘要

A damping system (10) having a rotation axis (X) and comprising at least: one first flyweight (14) and one second flyweight (14) able to oscillate with respect to a support member (12), and at least one device (20) for guiding the first and second flyweights (14) with respect to the support member (12), having at least one bearing element (22) able to interact with a pair of opposite tracks, respectively a first guidance track (24) and a second guidance track (26) that is carried by the support member (12), wherein the first guidance track (24) is carried by said connecting means (16).

1. A damping system (10) having a rotation axis (X) and comprising:
a support member (12) rotatable around the rotation axis (X); a first flyweight (14) and a second flyweight (14) configured to oscillate with respect to the support member (12) in a rotation plane orthogonal to the rotation axis (X), the first and second flyweights (14) being mounted axially on either side of the support member (12) and connected axially to one another by means of a spacer (16) passing axially through an associated opening (18) through the support member (12); and a guidance device (20) for guiding the first and second flyweights (14) with respect to the support member (12), the guiding device (20) cooperating only with the spacer (16), the guidance device (20) having a single rolling element (22) configured to interact with a pair of radially opposite tracks, respectively a single first guidance track (24) and a second guidance track (26) carried by the support member (12); the single first guidance track (24) being carried by the spacer (16); the spacer (16) non-moveably connected to each of the first and second flyweights (14) so that the first and second flyweights (14) being non-moveable relative to one another; the spacer (16) and each of the first and second flyweights being moveable relative to the support member (12); the single rolling element (22) interacting only with the first guidance track (24) of the spacer and the second guidance track (26) of the support member (12).
