Vibro-isolating supporting body

Abstract

Abstract PURPOSE:To improve a damping characteristic against low-frequency vibrations in particular, by housing a sponge body in the thickness specified in a diaphragm device partitioning the inside into a working chamber and a balanced chamber, while exposing the respective surfaces to each of these chambers aforesaid, in case of a vibro-isolating supporting body such as an engine mount and the like. CONSTITUTION:A supporting metal fitting 2 to be set to the engine side is solidly locked to a bottom metal fitting 6 via an elastic member 4 such as a conical, cylindrical rubber or the like, and a protecting cap 8 to be set to the car body side is locked to the lower end of the bottom metal fitting 6. A partition plate 10 is installed inside an engine mount like this, while a diaphragm 14 is set up at the lower side of the plate 10 whereby a working chamber 12 and a balanced chamber 16 are partitionarily made up, and a noncompressive fluid 18 is sealed up in each of these chambers 12 and 16. And, the partiton plate 10 is composed of each of rigid upper and lower plates 22, 24 and a sponge plate 38 to be housed in each of concave parts 32, 34 set up at the central opposite surface side of each of plates 22 and 24, while the respective surfaces of the sponge plate 38 are interconnected through to each of these chambers 12 and 16 via vent holes 40 and 42.
