摘要： A fluid-damped elastomeric bushing has an inner sleeve and an outer sleeve disposed outwardly of the inner sleeve, and two sidewalls extending between the inner sleeve and the outer sleeve and a partition wall to thereby form a pair of fluid compartments. The fluid compartments has a main chamber and a supplemental chamber in communication with the main chamber. An elastic support member extends radially outwardly from the inner sleeve toward the outer sleeve between the side walls to form a first main chamber and a second main chamber.An orifice device is disposed circumferentially along the outer sleeve for communicating the first and second main chambers for causing a fluid in one of the first and second main chambers to be forcibly fed to the other one of the first and second main chambers when a load is applied to the bushing.

摘要： A fluid-damped elastomeric bushing of the invention comprises an inner sleeve and an outer sleeve in a concentric or eccentric relation, an elastric member provided between the inner and outer sleeve, a plurality of liquid chambers or compartments provided in the central portion of the elastic member with respect to the axial direction of the sleeve, the liquid compartments being arranged along the circumference at specified intervals, and orifices to communicate at least the adjacent liquid compartments with each other. The elastic compartment wall of the elastic member has a portion bent toward the interior of the liquid compartment. A central part of the elastic compartment wall may have its thickness reduced relative to the other part.
