Abstract
A bearing suspension device includes first and second elastically flexible members extending in an axial direction; and first and second thrust points that are movable in the axial direction and that are in radial contact respectively with the first and second elastically flexible members. The bearing suspension device is configured to transmit a radial force by the first elastically flexible member bending between the first thrust point and a first end of the first elastically flexible member, and also to transmit the radial force by the second elastically flexible member bending between the second thrust point and a first end of the second elastically flexible member.

A bearing suspension device comprising:
- first and second elastically flexible members extending in an axial direction;
- and
- first and second thrust points that are movable in the axial direction and that are in radial contact respectively with the first and second elastically flexible members;
- the bearing suspension device being configured to transmit a radial force by the first elastically flexible member bending between the first thrust point and a first end of the first elastically flexible member, and also to transmit the radial force by the second elastically flexible member bending between the second thrust point and a first end of the second elastically flexible member, and the first and second elastically flexible members being connected together by respective second ends.
A method of varying the radial stiffness of a bearing suspension device, in which a radial force is transmitted by a bending moment via a first elastically flexible member between a first thrust point and a first end of the first elastically flexible member, and by a bending moment via a second elastically flexible member between a second thrust point and a first end of the second elastically flexible member, the first and second elastically flexible members being connected together by respective second ends, the method comprising a step of moving the first and second thrust points in the axial direction.
