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.

Abstract: A device for damping torsional oscillations, the device including at least one support capable of rotational displacement around an axis, at least one pendulum assembly, including at least one pendulum mass, the pendulum assembly being movable with respect to the support, at least one rolling member, each rolling member interacting with at least one first raceway defined by the support and with at least one second raceway defined by the pendulum assembly, the displacement of the pendulum assembly with respect to the support being guided by at least one of those rolling members, the device further including at least one friction member, carried by the pendulum assembly, for generating hysteresis in all or parts of the relative displacements of the pendulum assembly and the support.
