Abstract
A torsional damper device comprises at least two coaxial parts disposed to rotate relative to one another within defined limits of relative angular displacement. Circumferentially acting elastic means operative between these parts over at least part of this relative angular displacement resist same. A first coaxial part comprises a hub and an annular hub flange around the hub, constrained to rotate with the hub for one circumferential direction. A second coaxial part comprises at least one annular guide ring around the hub free to rotate relative to it in both circumferential directions. The device further comprises an annular hub counter-flange around the hub constrained to rotate with the hub for one circumferential direction. The hub flange and the hub counter-flange are each free to rotate relative to the hub in the circumferential direction opposite that in which it is constrained to rotate with it. The result is that for one circumferential direction the hub flange is free to rotate relative to the hub and the hub counter-flange is constrained to rotate with it, whereas for the opposite circumferential direction the hub flange is constrained to rotate with the hub and the hub…
