Abstract
A variable elastic coupling assembly interconnecting a rod of a vehicle shock absorber and a structure to be damped in order to filter vibrations, comprises two rigid annular armatures, one of which is fastened to the rod, and the other to the structure. The armatures are bonded together through at least two elastomeric annular elements which delimit between them a closed space which is totally sealed with respect to the external environment, and which contains a gas phase and at least one liquid phase. The volume of the closed space is modified by the deformation under strain of the elastomeric annular elements.
