Abstract
A torsion damper comprising two coaxial parts which are mounted for rotation of one with respect to the other, with, interposed between these coaxial parts, apart from a centring element, circumferentially acting springs which are lodged in a cavity closed by the centring element, and friction device arranged outside the cavity. The friction device comprise, firstly, a cassette carried by one of the two coaxial parts, and secondly, a drive ring carried by the other coaxial part. The cassette includes at least two friction discs arranged to be coupled in rotation variously to the two coaxial parts of the damper, together with an axially acting resilient ring for holding the friction discs axially together.
