摘要:
The invention relates to a vibration damping device for a motor vehicle transmission chain comprising: - a first element and a second element (2) which are capable of movement in rotation about an axis of rotation X; - elastic damping means comprising an elastic blade (13, 14) mounted to rotate as one with the first element (3); and - a rolling body capable of movement with respect to the second element so as to be able to effect a curved path along at least a predetermined angular sector (A), the movement of the rolling body in a curved path with respect to the second element being accompanied by a movement of the rolling body along the elastic blade thereby causing it to flex.

A mechanism for filtering torque fluctuations is interposed between a crankshaft of an internal combustion engine rotating about an axis of revolution (100) and a transmission housing. This mechanism comprises a member to be dampened (14, 114, 214, 15) rotating about an axis of revolution (100), an oscillating flywheel (22, 122, 222) rotating about the axis of revolution (100) relative to the member to be dampened (14, 114, 214), and articulated modules (26, 126, 226) allowing angular displacement of the oscillating flywheel (22, 122, 222) relative to the member to be dampened (14, 114, 214) to either side of a position of equilibrium. The articulated modules (26, 126, 226) each comprise at least one oscillating arm (26.1, 226.1) that pivots radially relative to the member to be dampened and a driving member (26.4, 226.4, 26.40) between the oscillating arm (26.1, 226.1) and the oscillating flywheel (22, 122, 222), positioned such that when the mechanism rotates about the axis of revolution (100), the centrifugal forces on the oscillating arm (26.1, 226.1) generate a countertorque on the member to be dampened (14, 114, 214, 15) that tends to return the oscillating flywheel (22, 122, 222) and the member to be dampened (14, 114, 214) to the position of equilibrium. The countertorque increases with the rotational speed of the filtering mechanism and with the amplitude of angular displacement. The filtering mechanism further comprises a primary member (12, 112, 212) kinematically interposed between the crankshaft and the member to be dampened (14, 114, 214), the member to be dampened forming a secondary member rotating about the axis of revolution (100) relative to the primary member (12, 112, 212).
摘要:
The invention relates to a damper (1), in particular for a motor vehicle clutch, said damper comprising: an input element; an output element that can rotate in relation to the input element about a rotation axis (X); and damping means disposed between the input and output elements, said damping means comprising a spring plate (17a, 17b) mounted on either the input element or the output element and disposed between said elements such as to bend and transmit a torque from the input element to the output element or vice versa. In a first operating phase, variations in the transmitted torque are accompanied by a relative rotation between the input element and the output element and the bending of the spring plate. In a second operating phase, variations in the transmitted torque are accompanied by the joint rotation of the input element and the output element.

The invention relates to a torque transmission unit including a driving member (1) comprising grooves (24) that are inserted with play into complementary grooves (9) of a driven member (2). A play take-up element (13) is mounted movably on the driven member (2) or on the driving member (1) between a first position in which same does not exert any stress on the grooves (9, 24) and a second position in which same urges the grooves of one of said members (1, 2) against the grooves of the other member, elastic return means (8) urging the play take-up element (13) towards the second position thereof. Means (19) for locking the play take-up element (13) lock the elastic return means (8) in an inactive position. The elastic return means (8) are released during operation of the torque transmission unit.
