ABSTRACT:
A MacPherson Strut assembly, or the like, with a hydroelastic suspension attachment in which the attachment is formed by two thick membranes of elastomeric composition which enclose a liquid. This unit forms a hydroelastic cartridge in which a sliding flap, provided with sealing joints, can move within a rigid confinement cup. The flap itself is encircled by a liquid passage having a large cross section clearance which causes a high level damping of vibrations which result from the resonant movement between masses between which the suspension attachment is mounted.
