Abstract: An elastic link comprising a first sleeve and a second sleeve. The first sleeve comprises a first elastic body, a first inner armature surrounded by the first elastic body, and a first outer armature surrounding the first elastic body. The second sleeve comprises a second elastic body, a second inner armature surrounded by the second elastic body, and a second outer armature surrounding the second elastic body. The first elastic body and the second elastic body presenting different elastic behaviors. This constitutes an improved elastic link.

Abstract: An elastic articulation comprising a first sleeve and a second sleeve is provided. The first sleeve and the second sleeve each include a respective outer armature, a respective inner armature, and a respective elastic body between their respective outer and inner armatures. The elastic articulation also comprises a ring longitudinally connecting the first sleeve and the second sleeve. The ring forms a radial stop between the inner armature and the outer armature of the first sleeve, and between the inner armature and the outer armature of the second sleeve. The elastic articulation improves damping control in different directions.

Abstract: A suspension support device for a motor vehicle comprises an inner strength member comprising a support base and an annular side wall, an outer strength member having a side wall surrounding the side wall of the inner strength member, an elastomer body comprising a load-supporting portion interconnecting the inner and outer strength members. The outer strength member has a bottom portion located under the support base of the inner strength member, extending parallel to the support base and presenting a central passage for passing the top portion of a shock absorber. The side wall of the outer strength member includes a window between the support base of the inner strength member and the bottom portion of the outer strength member, the device including a cavity under the load-carrying portion of the elastomer body.

Abstract: A hydraulic antivibration device comprises an inner strength member and an outer strength member together with an elastomer body disposed between the inner and outer strength members. The elastomer body includes at least two sets of two hydraulic chambers the chambers in any one set intercommunicating via a duct in which a fluid flows. The device includes a window strength member disposed inside the elastomer body and including at least one plate element close to the outer strength member. The ducts interconnect two chambers of a given set via at least a portion situated between a plate element of the window strength member and the outer strength member, and include walls formed by the elastomer body.

Abstract: An antivibration device comprising an inner strength member, an outer strength member, and an elastomer body interconnecting the inner and outer strength members, the elastomer body defining at least a first liquid-filled chamber, the device being characterized in that the first chamber is leaktight and disposed between the inner strength member and the outer strength member.

The side wall of the outer strength member includes a window between the support base of the inner strength member and the bottom portion of the outer strength member, the device including a cavity under the load-carrying portion of the elastomer body.

Abstract: Hydraulic antivibration pivot comprising coaxial internal and external reinforcements connected by an elastomer body that defines two hydraulic chambers communicating with each other through a throttled passage. An intermediate reinforcement embedded in the elastomer body comprises two rigid annuluses about which the external reinforcement is tightened, the said annuluses having collars that project from this reinforcement. The external reinforcement is immobilized between the two collars, which means that axial loads are absorbed without the risk of the pivot becoming detached.
