Abstract

Un ammortizzante ruotante comprende un involucro in materia plastica a forma di bacino (10) avente una parete circolare inferiore (1), una parete cilindrica periferica esterna (12) che sale dalla periferia esterna della parete di fondo circolare, una parete anulare interna (13) che sale dalla parete di fondo circolare e disposta più bassa e concentrica rispetto alla parete cilindrica periferica esterna, una porzione di albero fisso (14) che sale dal centro della parete di fondo circolare; un grosso anello torico (41) alloggiato nello spazio anulare tra la parete cilindrica periferica esterna (12) e la parete anulare interna (13); un rotore (20) avente una porzione di lastra di smorzamento (21) e una porzione di albero ruotante (22) che sale dal centro della porzione di lastra di smorzamento; un piccola anello torico (42) disposto sulla periferia esterna della porzione di albero ruotante (22) del rotore (20); un coperchio (30) costituito da una porzione a coppa (31) e una porzione di flangia (32); e fluido viscoso (43) disposto nello spazio circondato dalla parete anulare interna (13) dell'involucro a forma di bacino (10). L'involucro a forma di bacino (10) ha una pluralità di griffe di ritegno (15) per trattenere la porzione marginale periferica della porzione di flangia (32) del coperchio (30) ed impedire che il coperchio sfugga verso l'alto. La superficie inferiore della porzione di flangia (32) del coperchio (30) trattenuta dalle griffe di ritegno (15) è portata in contatto con la superficie superiore della porzione di lastra di smorzamento (21) del rotore (20) tramite il fluido viscoso (43).A rotating shock absorber comprises a basin-shaped plastic casing (10) having a lower circular wall (1), an external peripheral cylindrical wall (12) which rises from the outer periphery of the circular bottom wall, an internal annular wall (13 ) rising from the circular bottom wall and arranged lower and concentric with respect to the external peripheral cylindrical wall, a fixed shaft portion (14) rising from the center of the circular bottom wall; a large toric ring (41) housed in the annular space between the external peripheral cylindrical wall (12) and the internal annular wall (13); a rotor (20) having a portion of the damping plate (21) and a portion of the rotating shaft (22) which rises from the center of the portion of the damping plate; a small toric ring (42) arranged on the outer periphery of the rotating shaft portion (22) of the rotor (20); a cover (30) consisting of a cup portion (31) and a flange portion (32); and viscous fluid (43) disposed in the space surrounded by the inner annular wall (13) of the basin-shaped envelope (10). The basin-shaped casing (10) has a plurality of retaining claws (15) for holding the peripheral marginal portion of the flange portion (32) of the cover (30) and preventing the cover from escaping upwards. The lower surface of the flange portion (32) of the cover (30) held by the retaining jaws (15) is brought into contact with the upper surface of the damping plate portion (21) of the rotor (20) by means of the viscous fluid ( 43).
