Abstract
The invention relates to a hydroelastic joint that is used to assemble two pieces. The inventive joint comprises an external reinforcement () and an internal reinforcement (), each having a longitudinal axis, and one of which is disposed around the other. Moreover, said joint comprises a first assembly () forming a hydroelasctic spring which is disposed between said reinforcements. The aforementioned first assembly comprises a first elastically-deformable element () which is shaped in such a way as to define, between the reinforcements, at least one sealed volume () that contains a damping fluid (). A second elastically-deformable element () is disposed between the first assembly and the first of said external and internal reinforcements. The invention is characterized in that the second elastically-deformable element () is provided with a longitudinal dimension which is smaller than the corresponding longitudinal dimension of the first elastically-deformable element (). In this way, the transversal deformation of the first elastically-deformable element () is limited during the relative tilting of the longitudinal axes of said reinforcements around at least one transverse tilting axis (D).
