Abstract
An engine mount assembly for mounting an engine which produces a torque to a body having a persistent troublesome frequency vibration is disclosed. The engine mount assembly includes two fluid elastomeric chambers groundable to the body, an intermediate cradle link disposed between the two fluid chambers, a lateral link grounded to the body and the intermediate cradle, and a fluid conduit connecting the two fluid chambers. When subjected to torque a positive fluid pressure is generated within the fluid chambers and fluid conduit with the two fluid chambers share a plurality of loads while a transfer of the persistent troublesome frequency vibration from the body to the engine is inhibited.

An engine mount assembly for mounting an engine which produces a torque to a body having a persistent troublesome frequency vibration,
- said engine mount assembly including a first side fluid chamber fluid elastomer engine mount and a second side fluid chamber fluid elastomer engine mount, said first side fluid chamber fluid elastomer engine mount groundable to said body having said persistent troublesome frequency vibration, and said second side fluid chamber fluid elastomer engine mount groundable to said body having said persistent troublesome frequency vibration, said first side fluid chamber fluid elastomer engine mount having a first fluid chamber, said second side fluid chamber fluid elastomer engine mount having a second fluid chamber,
- an intermediate cradle with a lateral link, said lateral link having a first end for grounding to said body having said persistent troublesome frequency vibration and a second distal end, said second distal end distal from said first end, said second distal end linked to said intermediate cradle,
- said first side fluid chamber fluid elastomer engine mount grounded to said body having said persistent troublesome frequency vibration, said second side fluid chamber fluid elastomer engine mount grounded to said body having said persistent troublesome frequency vibration, with said intermediate cradle disposed between said first fluid chamber fluid engine mount and said second side fluid chamber fluid engine mount and said engine, with a fluid conduit connecting said first side fluid chamber fluid engine mount fluid chamber with said second side fluid chamber fluid engine mount fluid chamber wherein said torque generates a positive fluid pressure within said fluid chambers and said fluid conduit and said intermediate cradle has an intermediate cradle center cradle joint between said first side fluid chamber fluid elastomer engine mount and said second side fluid chamber fluid elastomer engine mount with said first side fluid chamber fluid elastomer engine mount and said second side fluid chamber fluid elastomer engine mount sharing a plurality of loads while a transfer of said persistent troublesome frequency vibration from said body to said engine is inhibited.
