（産業上の利用分野）
本考案は特に自動車とエンジンユニツトとの間
に介在させて防振をはからせるための液体封入防
振ゴム装置に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention particularly relates to a liquid-filled vibration isolating rubber device that is interposed between an automobile and an engine unit to provide vibration isolation.
（従来の技術）
自動車用エンジンから発生する振動騒音には、
アイドル振動などの低周波振動と、高速走行中に
車室内に生じるこもり音などの高周波振動と、そ
れ等両振動領域の中間の中周波振動とがあるが、
それ等各振動による騒音は互いに特性が異なるた
めに全てを同時に解消し得る防振ゴム装置の開発
が急がれている。(Conventional technology) Vibration noise generated from automobile engines includes
There are low-frequency vibrations such as idle vibrations, high-frequency vibrations such as the muffled noise that occurs inside the vehicle during high-speed driving, and medium-frequency vibrations between these two vibration ranges.
Since the noise caused by each type of vibration has different characteristics, there is an urgent need to develop a vibration isolating rubber device that can eliminate all of them at the same time.
そこで、ゴム等の環状弾性部材を室壁に用いる
と共に、減衰媒体として水などの非圧縮性流体を
液室内に密封してオリフイスを介してダンパ効果
をもたせるようにした液体減衰付防振ゴム装置が
汎く採用されるようになつてきている。 Therefore, a vibration isolating rubber device with liquid damping uses an annular elastic member such as rubber for the chamber wall and seals an incompressible fluid such as water as a damping medium in the liquid chamber to provide a damper effect via an orifice. is becoming widely adopted.
（考案が解決しようとする問題点）
ところがこの種の防振ゴム装置は、オリフイス
を有して前記液室内に設けた仕切板が一般に剛性
が高くて、しかもアツパプレートなどの板体に固
定されているので、ダンパ液室の液圧が上昇する
ことがあつて、その結果、高周波領域では動ばね
定数が大きくなることがあつた。(Problem to be solved by the invention) However, in this type of vibration-isolating rubber device, the partition plate that has an orifice and is installed in the liquid chamber generally has high rigidity, and is fixed to a plate body such as an Atsupa plate. As a result, the hydraulic pressure in the damper liquid chamber may increase, and as a result, the dynamic spring constant may increase in the high frequency range.
一方、高周波領域の振動を特に吸収する特性の
仕切板を利用したのでは、中、低周波数領域の振
動に対する動作特性が好ましくなく広範囲の振動
に対して安定した動作特性を有し得る装置とはい
い難かつた。 On the other hand, if a partition plate with characteristics that particularly absorbs vibrations in the high frequency range is used, the operating characteristics against vibrations in the medium and low frequency ranges are unfavorable, and it is not possible for a device to have stable operating characteristics against a wide range of vibrations. It was very difficult.
さらに、環状弾性部材と液室の外壁を形成する
筒体との間の結合強度の高いものが得られにくく
て、環状弾性部材の耐久性が劣るのと環状弾性部
材の軸直角方向のバネ定数が低くて振動吸収性に
問題があつた。 Furthermore, it is difficult to obtain a high bonding strength between the annular elastic member and the cylinder forming the outer wall of the liquid chamber, resulting in poor durability of the annular elastic member and a spring constant in the direction perpendicular to the axis of the annular elastic member. There was a problem with vibration absorption due to low vibration.
本考案は従来のこの種装置が有する欠点を排除
することを技術的課題とし、特に静バネ定数及び
低周波数領域の振動に対する減衰係数を変えるこ

ならしめ、さらに環状弾性部材の耐久性増大なら
びに軸直角方向のバネ定数を上げるようにして、
静粛性の向上と振動の有効なしや断とを果させよ
うとするものである。 The technical challenge of this invention is to eliminate the drawbacks of conventional devices of this type.In particular, the dynamic spring constant in the medium and high frequency ranges can be adjusted without changing the static spring constant and the damping coefficient for vibrations in the low frequency range. In addition, the durability of the annular elastic member is increased and the spring constant in the direction perpendicular to the axis is increased.
The aim is to improve quietness and effectively eliminate or eliminate vibration.

ある。(Means for Solving the Problems) For this purpose, the present invention combines a boss portion 1 attached to the engine unit side or the vehicle body side and a plate body 4 attached to the vehicle body side or the engine unit side into a lid-shaped integral body. An annular elastic member 3 is interposed between one end of the cylinder body 2 and the other end of a cylinder 2 arranged concentrically around the boss portion 1, and a diaphragm 5 is disposed in the space surrounded by the annular elastic member 3. A partition plate made of an elastic body is provided with a liquid chamber 8 surrounded by the diaphragm 5, the cylindrical body 2, the annular elastic member 3, and the boss portion 1, and is provided with an orifice 7 communicating in the thickness direction. 6
is interposed in the liquid chamber 8, and the liquid chamber 8 is divided into a first damper liquid chamber 8A facing the annular elastic member 3 and a second damper liquid chamber 8B facing the diaphragm 5. It is formed in a vibration-proof rubber device.

る。(Function) The present invention has an annular elastic member 3 for high frequency vibration.
The middle and low frequency vibrations are absorbed by the liquid flowing in and out of the liquid chamber 8 through the orifice 7, and the partition plate 6 vibrates minutely in response to the high frequency vibrations to reduce the liquid pressure. Thus, the dynamic spring constant decreases due to the decrease in hydraulic pressure, and the soundproofing performance against muffled sounds is improved.
また、環状弾性部材３は予圧縮が与えられてい

室への侵入を抑えることが可能である。 By the way, in the above-mentioned high frequency motion region, the amplitude of vibration is small and the liquid pressure in the liquid chamber 8 normally rises, but in this device, the inner part of the partition plate 6 is elastic and thin, so it is easy to vibrate. As a result, a volume change occurs, and thus the fluid pressure in the fluid chamber 8 decreases, and the dynamic spring constant decreases, making it possible to absorb muffled sound and transmitted sound and prevent them from entering the passenger compartment.
