摘要： In a duo-pumping hydraulic mount, two acting pistons are employed, one associated with each working chamber. The pistons are rigidly connected. During operation, internal pressures generated in each chamber are opposite in sign with one being negative and the other being positive. Therefore, to achieve a given pressure differential across the fluid track, the magnitude of the pressure in each working chamber is half what would be experienced in a conventional single pumping mount. Durability is improved by reducing internal pressures and by distributing kinetic loads to two rubber elements so that individual stresses are minimized. An individual load bearing element supports static loads on the mount.

摘要： 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.

摘要： A hydraulic mount is operable in soft and firm modes and includes a valve positioned at the partition between the working chamber and the reservoir. A normally open fluid path extends through the partition and opens between the working chamber and the reservoir for soft operational characteristics useful in attenuating low amplitude vibrations. The valve body and the partition together define a control chamber in the fluid path. The control chamber is open to the reservoir through lateral openings in the valve body so that fluid pressure in the control chamber is approximately at atmospheric pressure so that a small actuator can move the valve. When the valve is closed the fluid path is closed for firm operational characteristics in controlling large amplitude inputs such as those from torque transients.
摘要翻译： 液压底座可以软和坚固的模式操作，并且包括位于工作室和储存器之间的隔板处的阀。 常开流体路径延伸穿过隔板并在工作室和储存器之间打开，用于衰减低振幅振动的软操作特性。 阀体和隔板一起在流体路径中限定了一个控制室。 控制室通过阀体中的侧向开口通向储存器，使得控制室中的流体压力近似为大气压，使得小的致动器能够移动阀。 当关闭阀门时，流体路径关闭以控制大幅度输入，例如来自扭矩瞬变的输入。
