<p>1. A torsion damping device, in particular for a friction clutch, especially for an automotive vehicle, of the kind comprising at least two coaxial parts (A, B) which are mounted so as to be movable with respect to each other within the limits of a predetermined angular displacement and against the action of resilient means (13), the said coaxial parts comprising a first part (B), which includes at least one radial plate (12), and a second part (A), which includes at least two guide rings (1, 2) which are disposed on either side of the said radial plate, one of the guide rings, namely a support ring (2), being fixed at its periphery to a crown member (3) which extends generally axially and radially beyond the radial plate and which is provided with openings (11), while the other guide ring, namely a closing ring (1), has disposed at intervals around its periphery at least two radially disposed tenons (4) by which it is engaged and located in notches (5) of the said crown member, the device being characterised in that, in combination, at least two of the said openings (11) communicate axially with at lest two of the said notches (5), and in that the crown member (3) is reinforced by at least one encircling strap (14) carried by the crown member and being offset with respect to the set of said tenons (4) of the closing ring (1) of which they from part.</p> |
