Abstract
A hydraulic mount includes a mounting plate and a wall, with a working chamber defined between the mounting plate and the wall. The mounting plate and the wall are separated by a relatively thick elastomeric element so that the size of the working chamber varies as the elastomeric element is compressed and expanded by operation of the mounting plate and the wall moving closer together and farther apart. A reservoir is defined substantially by the elastomeric element in combination with a relatively flexible diaphragm that extends between the mounting plate and the wall so that the reservoir is generally annular in shape and is positioned around the working chamber. The elastomeric element serves as a separation wall between the working chamber and the reservoir. The mount includes a fluid track extending through the wall and opening between the working chamber and the reservoir, with a fluid contained in the working chamber, the reservoir and the fluid track, so that the mount is tunable by varying the size of the fluid track.
