Abstract
This invention is concerned with a torsion damping device for an automotive vehicle, of the kind comprising two coaxial parts and an intervention member for modifying the operating characteristics of the damping device. One of the two coaxial parts includes a hub, and the intervention member comprises at least one plate, resiliently deformable in the radial direction and with the hub extending through it. The intervention plate has, at its inner periphery, an inner surface which is adapted to come into engagement on an abutment surface which is fixed with respect to the outer periphery of the hub. The plate is fixed axially in at least two points to one of the said coaxial parts of the torsion damper that is not rotatable with the hub. It is moveable radially between the said abutment surface of the hub and at least one end stop abutment forming part of one of the coaxial parts of the device.
