防振装置に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vibration isolator for absorbing vibrations of automobiles, etc., and particularly relates to a vibration isolator that includes a liquid chamber filled with liquid and absorbs vibrations. Regarding equipment.
液体が充填された液室を有した防振装置が用いられてい

収するようになっている。A vibration isolator having a liquid chamber filled with liquid is used (see, for example, Japanese Patent Laid-Open No. 113835/1983). This vibration isolator separates the liquid chamber into multiple small liquid chambers using a partition wall. This partition wall is provided with a communication path that communicates the small liquid chambers. Furthermore, a diaphragm is provided on the partition wall to absorb high frequency vibrations.

連通路の通過抵抗で吸収し、高周波振動時に連通路内の
液体が目づまり状態になると、振動板が振動してこの高
周波を吸収するようになっている。Therefore, in this vibration isolator, low frequency vibrations are absorbed by the passage resistance of the communication passage provided in the partition wall, and when the liquid in the communication passage becomes clogged during high frequency vibration, the diaphragm vibrates and absorbs this high frequency. It is supposed to be done.

振動を吸収できない場合が生ずる。However, with this vibration isolator, when a so-called compound vibration is applied, in which a high frequency, small amplitude vibration and a low frequency, large amplitude vibration overlap, the diaphragm moves by the maximum amount due to the low frequency vibration included in this compound vibration. There may be cases where the device remains stopped at a certain point, and high frequency vibrations cannot be absorbed.
本発明は上記事実を考慮し、複合振動が入力された場合
にも、これを適切に吸収することができる防Ｊｌｉ装置
を得ることが目的である。The present invention takes the above-mentioned facts into account, and aims to provide an anti-JLI device that can appropriately absorb complex vibrations even when they are input.

ることを特徴としている。A vibration isolator according to the present invention includes a liquid chamber that can be expanded and contracted, a partition wall that partitions the liquid chamber into a plurality of small liquid chambers, a first communication path that communicates the small liquid chambers with each other, and a first communication path that communicates with the small liquid chambers. a second communicating path having a large area; an electrorheological fluid provided corresponding to at least the second communicating path; and an electrode provided in the second communicating path; It is characterized by having an alternating voltage control n means for changing the viscosity of the fluid fluid.

大きな圧力上昇を抑えて振動が吸収される。Therefore, in the present invention, the ill! Since the energized electrorheological fluid has a large viscosity, the electrorheological fluid in the second communication path periodically increases its viscosity in accordance with the frequency of the alternating voltage. As a result, low-frequency large-amplitude vibrations with a frequency lower than the frequency of the alternating voltage cannot pass through the second communication path, and high-frequency vibrations higher than the frequency of the alternating voltage pass through the second communication path and are opposed. This leads to the liquid chamber on the side, suppressing a large pressure rise in the liquid chamber and absorbing vibrations.

昇することはなく振動が吸収される。Furthermore, when the vibration becomes high frequency, the liquid 3 in the first communication path 42
0 is a clogged state, so vibrations cannot be absorbed in this first communicating path 42. However, when the electricity to the electrodes 50, 52 is removed, the liquid 30 moves to the lower liquid chamber 30B through the second communication path 48, so the pressure in the upper liquid chamber 30A does not increase and vibrations are absorbed.

It is not possible to pass through the communication path 48, and high frequency swing J
Only the diaphragm 18 passes through this second communication path 48
transform. As a result, vibrations are absorbed within this second communication path and in the other small liquid chamber through which it passed.
