摘要:
A device (1) for damping torsional oscillations, comprising: - a support (2) that is able to be moved in rotation about an axis (X), - at least one first (3) and one second (4) pendular mass that are axially spaced apart from one another and are able to move with respect to the support (2), the first pendular mass (3) being disposed on a first side (10) of the support (2) and the second pendular mass (4) being disposed on a second side (11) of the support (2), - and two connecting members (5) for connecting the first (3) and the second (4) pendular mass such that said masses are matched, the connecting members (5) being angularly spaced apart from one another, each connecting member (5) being partially held in an opening (25) formed in the holder (2), and each connecting member (5) extending angularly in the anticlockwise direction from a first end (5.1) to a second end (5.2) of said connecting member (5), each connecting member (5) being associated with a stop member (40) for the movement of the pendular masses (3, 4) with respect to the support (2), the stop member (40) associated with one of the connecting members (5) being closer to the first end (5.1) thereof than to the second end (5.2) thereof, while the stop member (40) associated with the other connecting member (5) is closer to the second end (5.2) thereof than to the first end (5.1) thereof.
摘要:
The invention relates to an arrangement for attaching a frictional modular clutch device (20) for an automobile on a first driven shaft (24A), that comprises a reaction plate (28) rotatingly mounted about a journal (34) of the first driven shaft (24) via a rolling bearing (30) during a mounting operation, that comprises a blocking member (44) which, during an attachment operation, is placed by elastic deformation in an attachment position in an attachment groove (46) associated with the journal (34) of the first driven shaft (24A) in order to limit the backward axial movement of the rolling bearing (30), characterised in that before the attachment operation, the blocking member (44) is in a rest position in which it is carried by the clutch device (20).
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.
