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.

Abstract: A pendulum damping device including a support that rotates about an axis, at least one pendulum body and at least one rolling member guiding the movement of the pendulum body relative to the support, the rolling member engaging with at least one rolling track rigidly connected to the support and with at least one rolling track rigidly connected to the pendulum body. The rolling member includes a first part defining a first axial end, a second part defining a second axial end, and a resilient element arranged in the rolling member so as to axially separate these two parts so that the rolling member exerts an axial clamping force on one of the pendulum body and the support during the movement of the pendulum body relative to the support.
