Abstract
This present invention is concerned with torsion dampers of the kind comprising two coaxial parts which are mounted for rotation with respect to each other against the action of circumferentially acting resilient means in the form of at least one spiral spring comprising a resiliently deformable arm with an inner carrier element and an outer carrier element, one of which is connected through a profiled coupling with one of the rotatable coaxial parts of the damper, for rotation with it. The other (second) carrier element is coupled with the other coaxial damper part (the second coaxial part) through a gripping action, the second coaxial part being subjected to the action of an axially acting spring element which is engaged axially on the second coaxial part and which urges the second carrier element towards a radial thrust surface formed on the second coaxial part, so as to make contact, directly or indirectly, with the thrust surface. The invention is especially applicable to a damper of a damped double flywheel for an automotive vehicle.
