Abstract

A two-chamber engine mount with hydraulic damping includes rubber-elastic peripheral walls, a rigid intermediate plate disposed within the peripheral walls defining two chambers along with the peripheral walls being acted upon by vibrations induced in a given direction, hydraulic fluid filling the chambers, the intermediate plate having a channel formed therein interconnecting the chambers, the intermediate plate having another chamber formed therein, and a rubber-elastic membrane disc having two sides and being loosely disposed in the other chamber, both of the sides of the membrane disc being acted upon by the hydraulic fluid moving the membrane disc parallel to the given direction for combined frequency and amplitude decoupling.
