  • Publication number: 20210062891
    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.

  • Publication number: 20200072316
    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.

  • Patent number: 10359082
    Abstract: A torsional damper for vehicle transmission systems comprises an input element rotationally movable around an axis and exhibiting at least one window comprising two angularly spaced lateral edges and a radially external edge. An output element is rotationally movable around the axis and exhibits at least one window comprising two angularly spaced lateral edges and a radially external edge. An elastic return member capable of being received simultaneously in the window of the input element and the window of the output element generates a force acting against rotation of the output element with respect to the input element. An additional element is rotationally movable around the axis and integral with one of the input element and output element. The additional element exhibits an edge comprising at least one region projecting radially into the window of the input element and output element with which the additional element is integral.

  • Publication number: 20190170211
    Abstract: A pendulum device including a mounting, rotatably movable and capable of being rigidly connected to the component, and at least one pendulum body movable relative to the mounting, the movement of the pendulum body relative to the mounting being guided by at least one rolling member engaging with at least one first raceway rigidly connected to the mounting and at least one second raceway rigidly connected to the pendulum body, the pendulum body including first and second pendulum masses, and at least one member linking the first and second masses pairing the masses, the linking member being arranged in an opening of the mounting of which one portion of the contour defines the first raceway, characterised in that the linking member extends between a first plane and a second plane which are tangential to the linking member, the second raceway is defined by the contour of the linking member and extends from a third plane to a fourth plane which are secant to the linking member, and a first distance measured betwe

  • Patent number: 10215236
    Abstract: The invention relates on the one hand to a progressivity device for a clutch friction disk, comprising a progressivity web (1) having a central rotation axis (X), having on one face of its external rim (1a) a series of blades (2) on which are configured at least two deformable pleats (20a, 20b) delimiting a region (20) intended to support a first friction lining (G1) and equipped with a stiffness element, and on the other face a second friction lining (G2) fastened symmetrically to the first lining (G1), wherein the stiffness element comprises at least one tab projecting below the region (20), one end of which is intended to come into abutment against the web (1) upon deformation of the pleats (20a, 20b), limiting the arching of the region (20); and on the other hand to a friction disk comprising such a device.

  • Patent number: 9482306
    Abstract: This device comprises two coaxial elements mounted rotatably with respect to a spring, and two seats for positioning the spring. Each seat comprises a dorsal pivot projection configured in two coaxial elements. The pivot projection is delimited by a cylinder portion whose section is a first circular arc whose tangent forms an angle ? with the axis of the spring. The section of each receptacle is formed by a second circular arc, having the same center and radius of curvature as the first circular arc, the tangent of which forms with the axis of the spring an angle ? greater than ?. The pivot axes are parallel to one another at a distance L, and are included in a plane located at a distance R from the rotation axis. The maximum deflection angle of the device is ?. ? is within the range [arctg(L/2R)??/8 to arctg(L/2R+?].
