Abstract
An engine mount is provided to change properties based on magnitudes of amplitudes input to the engine mount. The engine mount includes a membrane having a central portion and an outer circumferential portion. Upper and lower orifice brackets are mounted between an insulator and a diaphragm to divide an interior of a main casing into an upper liquid chamber and a lower liquid chamber. The upper and lower orifice brackets define a flow path that enables a fluid to flow between the upper and lower liquid chambers and define a receiving space in which the membrane is movable in a vertical direction. An air chamber is connected to a lower side of the lower orifice bracket and allows a lower portion of the membrane to be exposed to air.
Claims9
An engine mount, comprising:
- a membrane including a central portion and an outer circumferential portion;
- upper and lower orifice brackets mounted between an insulator and a diaphragm to divide an interior of a main casing into an upper liquid chamber and a lower liquid chamber, the upper and lower orifice brackets defining a flow path that enables a fluid to flow between the upper and lower liquid chambers, and defining a receiving space in which the membrane is movable in a vertical direction;
- and
- an air chamber connected to a lower side of the lower orifice bracket and allowing a lower portion of the membrane to be exposed to air,
- wherein the upper orifice bracket has a fixing aperture into which the central portion of the membrane is inserted,
- wherein the membrane freely vibrates when a magnitude of a first input amplitude is generated, and
- wherein the fluid moves through the flow path when the membrane moves in the vertical direction and stops when a magnitude of a second input amplitude, which is greater than the magnitude of the first input amplitude, is generated.
