An engine mount is described as having two concentrically disposed annular resilient rubber springs, the outermost of which is provided with a pair of cavities and connecting passageway for receiving a dampening fluid. The spring rates of the two rubber springs can be individually tuned by the use of voids or cavities. Thus, there is a threefold manner in which the spring rate of the engine mount can be tuned.

Dual elastomeric/fluid engine mount

An elastomeric hanger structure is designed to provide both force stabilization and vibration isolation while connecting a part such as a vehicle exhaust system with a supporting structure such as a vehicle chassis. The elastomeric hanger of the invention is also capable of being selectively tailored to control numerous static and dynamic conditions which may be encountered when the part is suspended.
