Abstract

Le palier amortisseur de choc comprend une pièce monobloc (1) définissant une partie centrale (4), une partie périphérique (5) et un organe élastique (6) reliant la partie centrale (4) à la partie périphérique (5). La partie centrale (4) présente un trou (7) destiné à recevoir un pivot (8). L'organe élastique (6) comprend une partie intermédiaire mobile (11) entourant l'axe imaginaire (13), un premier ressort (10a) comprenant au moins un bras élastique (12a) reliant la partie centrale (4) à la partie intermédiaire mobile (11) et un deuxième ressort (10b) comprenant au moins un bras élastique (12b) reliant la partie intermédiaire mobile (11) à la partie périphérique (5). Les premier et deuxième ressorts (10a, 10b) ont des raideurs différentes dans l'une au moins de la direction de l'axe imaginaire (13) du trou (7) et de la direction radiale par rapport à cet axe imaginaire (13).
