Abstract:
A hydraulic mount comprising:a first mounting plate and a wall, with a first working chamber defined between the first mounting plate and the wall, wherein the first mounting plate and the wall are separated by a relatively thick first elastomeric element so that the size of the first working chamber varies as the first elastomeric element is compressed and expanded by operation of the first mounting plate and the wall moving closer together and farther apart;a reservoir defined substantially by the first elastomeric element in combination with a relatively flexible diaphragm so that the reservoir is positioned around the first working chamber so that the first elastomeric element serves as a separation wall between the first working chamber and the reservoir, wherein the diaphragm includes an outside surface that is exposed to atmospheric pressure;a first fluid track extending through the wall and opening between the first working chamber and the reservoir wherein a fluid is contained in the first working chamber, the first reservoir and the first fluid track, wherein the hydraulic mount is tunable by varying the size of the first fluid track;a second mounting plate positioned on an opposite side of the wall from the first mounting plate with a second working chamber defined between the wall and the second mounting plate wherein the wall and the second mounting plate are separated by a relatively thick second elastomeric element so that the size of the second working chamber varies as the second elastomeric element is compressed and expanded by operation of the second mounting plate and the wall moving closer together and farther apart; anda second fluid track extending through the wall and opening between the second working chamber and the reservoir wherein the fluid is also contained in the second working chamber and the second fluid track wherein the hydraulic mount is also tunable by varying the size of the second fluid track.
