ABSTRACT:
A two-chamber engine mount with hydraulic damping, includes a housing, an intermediate plate disposed in the housing dividing the housing into an upper chamber above the intermediate plate and a lower chamber below the intermediate plate to be filled with fluid, the intermediate plate having a damping opening formed therein hydraulically interconnecting the chambers for preventing a hydraulic response upon the occurrence of high frequency and low amplitude vibrations, upper and lower rubbery elastic peripheral walls at least partially defining the upper and lower chambers, respectively, a motor support plate adjacent the upper chamber, the support plate having a membrane chamber centrally formed therein, and a rubbery membrane separating the membrane chamber from the upper chamber, the rubbery membrane including a solid central quenching mass.
