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 insert is embedded in the base of the elastomer body and is crimped to the plate via two fixing edges that are interconnected by two free edges of the base. A rigid cover covers the elastomer body and has flanges which are fixed directly against the plate, the flanges extending towards the elastomer body in the form of bearing zones which press against the free edges of the base of the elastomer body.
