ABSTRACT:
A torsional damper device comprises at least three coaxial parts rotatable relative to one another in pairs within defined limits of relative angular displacement. Such rotation occurs against circumferentially acting elastic members operative between them over part at least of such relative angular displacement. A first coaxial part comprises a hub. A second coaxial part comprises at least one transverse annular hub flange around the hub. First teeth with clearance are disposed between the hub and the hub flange. A third coaxial part comprises at least one transverse annular flange around but having no direct relationship with the hub, parallel to the hub flange. The second part further comprises at least one transverse annular auxiliary flange around the hub, parallel to and associated with the hub flange. Second teeth with clearance are disposed between the auxiliary flange and the hub. The first and second teeth are in an alternating arrangement, the overall arrangement of the device being such that for a first circumferential direction of relative angular displacement between the first and second parts the hub flange becomes operative first, whereas for the opposite circumferential direction of relative angular displacement the auxiliary flange becomes operative first.
