Abstract
Abstract There is disclosed a hydraulic-elastomeric mount comprising a pair of mounting members that are interconnected by a hollow elastomeric body, an elastomeric diaphragm that closes the elastomeric body to form a closed cavity filled with liquid and a partition and orifice assembly that divides the cavity into a chamber enclosed by the elastomeric body and a chamber enclosed by the diaphragm. The partition and orifice assembly comprises a partition plate that actually separates the chambers and an annular plate wherein the plates have mating faces with oppositely facing channels formed therein that cooperatively define at least one orifice between the plates extending in a plane along and adjacent the periphery of the plates with each of the plates further having an opening therethrough to one end only of the orifice so that it interconnects the chambers and has a length which may thereby be made substantially as expansive as the periphery of the plates or made shorter by shortening one channel relative to the other. There is also a two-piece damping decoupler assembly that fits together through and has a limited travel connection with the partition plate so as to effect limited cyclic volume change in the chambers and thereby permit limited vibratory amplitudes at low frequencies without hydraulic damping.
