Abstract
A pendulum damping device incorporated into a drive train of a motor vehicle, notably into a clutch, includes a support capable of rotational movement about an axis of rotation, a pendulum assembly of which the movement with respect to the support is guided by at least one rolling member, and an end-stop damping system borne directly by the pendulum assembly and able at least to damp the coming of said pendulum assembly into a position of abutment against the support of said pendulum assembly during the radial fall and/or saturation of this said pendulum assembly. The pendulum assembly also includes at least one radial protuberance designed to pass at least partially through an opening made in the end-stop damping system.
