Abstract

L'invention concerne le domaine des dispositifs de suspension de palier, et en particulier un dispositif de suspension (20) de palier avec une raideur radiale variable. Ce dispositif (20) de suspension de palier comprend un premier organe (21) élastiquement flexible s'étendant en direction axiale, et un premier point d'appui (28), mobile en direction axiale, en contact radial avec le premier organe (21) élastiquement flexible. Le dispositif de suspension de palier (20) étant configuré pour transmettre un effort radial (F) par flexion du premier organe (21) élastiquement flexible, entre le premier point d'appui (28) et une première extrémité (22) du premier organe (23) élastiquement flexible, sa raideur par rapport à cet effort radial peut être faite varier en déplaçant le premier point d'appui (28) en direction axiale, de manière à modifier la longueur du porte-à-faux axial sur lequel cet effort radial (F) est transmis par flexion du premier organe (21) élastiquement flexible.
