Abstract
A torsion damper which comprises two coaxial parts mounted for rotation relative to one another within the limits of a determined angular movement, and against the action of springs. There is also at least one intervening device which is sensitive to the angular movement between the parts and which is movable reversibly between a waiting position, in which it is inoperative, and, beyond a determined value of the movement, an operating position, in which the intervening device causes a modification of the operation characteristics of the torsion damper. The torsion damper is particularly usable in clutch plate assemblies for motor vehicles.
