Abstract

L'invention concerne un élément ressort axial (6) comprenant deux éléments annulaires (61, 62) périphériques espacés l'un de l'autre dans le sens axial, qui sont reliés élastiquement l'un à l'autre. Au moins un des éléments annulaires (61) est doté d'un ou de plusieurs éléments de retenue (64) pour assembler l'élément ressort à un rotor (5) et le retenir ainsi sur ce dernier.
