Abstract

Axially damping hydraulic mount is provided, relating to elastomer mounts for engine mounts for damping the vibrations transmitted from internal combustion engine to the body and for acoustic decoupling. The hydraulic mount includes a frustoconical elastomer support spring, between mount core and upper part of outer jacket, with a working chamber and a compensating chamber for fluid damping medium. Chambers are separated from one another by a separator extending transversely to the mount axis and includes a coupling diaphragm, wherein the working chamber is enclosed by support spring and separating element. Compensating chamber is enclosed by separating element and elastomer bellows. A duct on the separating element is enclosed by a duct part. To counteract excessive increase in dynamic spring rate when frequencies of axially acting vibrations are present, the duct part is occupied by an additional mass. Then the duct part is rigidly connected to a mass element.
