  • Torsion damping device of large angular displacement, particularly a friction clutch, especially for an automotive vehicle
    Patent number: 4969855
    Abstract: A torsion damping device for automotive vehicles, which comprises three coaxial parts (A, B, C) mounted rotatably with respect to each other against the action of circumferentially acting resilient springs, the second part (B) comprises two damper plates (12, 12') which, independently of each other, each comprise an annular member around the hub (10) which constitutes the first part (A), with, between them and the hub (10), relative rotational displacement devices which are arranged alternately as between one damper plate and the other. Circumferentially acting resilient springs (23, 23'), separate from each other, are interposed between, on the one hand, the hub (10) and one of the damper plates (12, 12'), and on the other hand, between the hub (10) and the other damper plate (12', 12).
