Synthetic engine mount strut

Claim 1

A resilient strut assembly for rigidly securing an engine to a vehicle frame to restrict engine torque induced motion, isolate engine and drive line vibration, and dampen engine torque reactions comprised of any one or more of pitch, yaw, and roll as characteristic of engine orientation, and comprising: a body of vigorous synthetic material composition having a high modulus of elasticity, said body having a closed geometric periphery with an open center extending completely therethrough and at least one non-linear integral and elongate brace having a first and second end, and extending through said open center, so as to partition at least a portion of said open center, said first and second ends being integral with said periphery of said body, the remainder of said brace exclusive of said first and second ends being disposed within said open center and in dissociated relationship with said periphery, said body having opposed ends for fastening to the engine and frame, respectively, and means for fastening opposed ends of said body to the engine and frame respectively in such a way that forces exerted on said body are primarily in a direction between said fastening means, said at least one brace providing for dampening of small displacement high frequency vibrations by said body, while restricting large displacement low frequency structural deformations of said body.
