ABSTRACT:
A hydraulic antivibration support comprises a strength member connected to a plate by an elastomer body whose base is pressed against the plate to define two hydraulic chambers and a narrow channel all filled with liquid. A perforated sheet metal insert embedded in the base of the elastomer body is crimped to the plate via two fixing edges that are interconnected by two free edges of the base. The perforated insert has a stamped corrugation which defines the narrow channel and whose outer side wall extends around the entire periphery of the plate.
