Abstract
A torsional vibration damping device (1), in particular for a motor vehicle clutch, said device comprising a disc (60) and a support (80) mounted mobile in rotation relative to each other about a common main axis, and linked in rotation via circumferential elastic members (90) damping torsional vibrations, said elastic members being interposed between the disc (60) and the support (80) and maintained in position circumferentially via lugs (65) of the disc (60) and lugs (82,84) of the support (80) whereon are supported the elastic members (90) and radially via a guide ring (100) passing through the elastic members (90) and integral with the disc (60). Said device is characterised in that the lugs (82,84) of the support (80) are mounted on either side of a section of the ring (100) and the lugs (65) of the disc (60) can move freely at the angle between the lugs (82,84) of the support (80).
