Description of the Related Art Liquid-filled mounts have good characteristics that cannot be realized by mounting using only an elastomer, and those disclosed in Japanese Patent Laid-Open No. 62-220729 are known in the past. . This liquid-filled mount controls the flow rate of hydraulic fluid that is repeatedly flowed between two liquid chambers via an orifice when vibration is input, by means of a valve inside the orifice that is opened / closed by a signal from a controller. However, the frequency characteristic (anti-vibration performance) can be switched according to the frequency range of the input vibration.

The present invention can effectively solve the problem. That is, the liquid-filled mount according to the present invention includes a main elastic support portion disposed substantially axially between the boss sleeve and an outer cylinder arranged around the boss sleeve, and diaphragms disposed at both axial ends. Define first and second liquid encapsulation parts independent of each other, and the first and second liquid encapsulation parts are defined by the elastic partition into a main elastic support part side liquid chamber and a diaphragm side liquid chamber, respectively. The main elastic supporting portion side liquid chamber and the diaphragm side liquid chamber of the first liquid sealing portion, and the main elastic supporting portion side liquid chamber and the diaphragm side liquid chamber of the second liquid sealing portion,
They are communicated with each other through orifices having different flowability. Further, in a preferred example of the present invention, the elastic partition wall is interposed between the boss sleeve and the outer cylinder in a state where the elastic partition wall is deformed from a substantially tapered original shape to a substantially disk shape having the same diameter as the original shape. .

ので、有効に防振される周波数域が拡大される。In this liquid-filled mount, one of the boss sleeve and the outer cylinder is the supporting side and the other is the supporting side so that the relative vibration between the supporting side and the supported side is mainly input in the axial direction. Connected to. For this reason, when the main elastic support portion and the diaphragm between the boss sleeve and the outer cylinder are repeatedly deformed by the input of vibration, the main elastic elasticity of the first liquid encapsulating portion and the second liquid encapsulating portion is increased accordingly. Since the volumes of the support part side liquid chamber and the diaphragm side liquid chamber are alternately enlarged and reduced, the enclosed liquid repeatedly moves through these orifices between these two liquid chambers,
The liquid column resonance is generated to insulate the transmitted vibration, and the vibration damping force is obtained by the flow resistance of the enclosed liquid moved on both sides of the flange. At this time, since the frequency characteristics of the liquid column resonance are different between the first liquid filling portion and the second liquid filling portion due to the orifices having different flowability, the frequency range in which vibration is effectively suppressed is expanded.

Since the original shape is deformed into a substantially disk shape having the same diameter as this original shape, it is appropriately pre-compressed and durability is improved.
