ABSTRACT:
A controllable elastic connection device for providing antivibration filtering having two different rigidities in a vehicle suspension system includes a piezo-rigid tubular chamber embedded in an elastomer compound block that is elastically connected between two fastening armatures, whereby the piezo-rigid tubular chamber is expandable under the action of a hydraulic pressure to increase the rigidity of the connection and thereby block the transverse deformability by a ratio of at least three.
