Abstract: A vibration damper is provided with two rotating members, i.e. an oscillating inertial flywheel and a member to be damped driven by a torque following a torque path between a driving member and a driven member, wherein the inertial flywheel is connected kinematically to the torque path between the driving member and the driven member solely by way of the member to be damped. Connecting modules between the two rotating members permit a relative angular displacement ? between the two rotating members on the two sides of a reference relative angular position. Each connecting module is provided with a roller associated with a first of the two rotating members and a cam track connected resiliently by a resilient element to a second of the two rotating members.

Abstract: A torque transmission assembly including a hydrodynamic torque convener able to be coupled to a crankshaft on the one hand, and able to be coupled to a gearbox input shaft on the other, the torque converter including a primary element and a secondary element which are rotationally mobile about an axis of rotation, and damping means including a transmission member and a bearing element, the transmission member including an elastic leaf rotating as one with the primary element or with the secondary element, and the bearing element being home by the secondary element or by the primary element respectively, the elastic leaf being capable of flexing and of transmitting a rotational torque between the primary element and the secondary clement, the flexing of the elastic leaf being accompanied by a relative rotation between the primary and secondary elements.

Abstract: A vibration damper for a torque transmission device comprising a first element and a second element which are rotatable relative to each other around an axis of rotation X; and damping means for transmitting a torque and damping the rotational acyclisms between the first element and the second element. The damping means comprise an elastic blade mounted securely on the first element and provided with a cam surface; and the damper comprises a cam follower carried by the second element and arranged to cooperate with the cam surface. The cam surface is arranged such that, for an angular travel between the first element and the second element relative to an angular rest position, the cam follower exerts a flexion force on the elastic blade producing a reaction force able to return the first and second elements to the angular rest position.

Abstract: A damper for an automobile clutch, comprises input and output elements rotationally movable with respect to one another around a rotation axis (X), and a damping device interposed between the input and output elements. One of the input and output elements is equipped with a cam follower (21). The damping device has a flexible blade (17a; 17b). The flexible blade is provided with a cam surface (20) arranged to interact with the cam follower. The cam surface extends over an opening angle (A) greater than 30°.

Abstract: A torsional damper having a disc (4), two guide washers (2,3), a hub (7) and low stiffness sprigs (8). The output member has a stepped annular flange (9) with a lower first area (73) and a second area (74) axially offset relative to the first portion. The second portion has teeth, and a bearing (91) is rotationally locked to the disc (4) to form a housing for the low stiffness springs (8).

Abstract: A clutch release bearing assembly comprises a coupling part adapted to couple a clutch release bearing to a clutch release device of a clutch. A substantially axial bush is attached to the clutch release device. There is an engagement bearing surface at the end of this bush. A drive part which is part of the clutch release bearing comprises an annular groove. A decoupling part is slidably mounted on the drive part. A fastening device operative in traction is disposed between the coupling part and the drive part. It couples these parts in the axial direction from the clutch release device to the clutch release bearing. It comprises an annular fastening ring which is disposed around the axis of the assembly. This ring is elastically deformable in the radial direction and at least partially interlocked on the clutch release bearing side with a bearing surface on the coupling part.
