Description

本発明は、一般産業機械、自動車のエンジンマウント等として用いられ、エンジン等の振動発生部からの振動を吸収して車体等の振動受部への振動伝達を抑制する防振装置、及び、この防振装置に用いられる防振装置用ブラケットに関するものである。   The present invention is used as a general industrial machine, an engine mount of an automobile, etc., and a vibration isolator that absorbs vibration from a vibration generating part of an engine or the like and suppresses vibration transmission to a vibration receiving part such as a vehicle body, and the like The present invention relates to a vibration isolator bracket used for a vibration isolator.

例えば、車両の振動発生部であるエンジンと振動受部である車体との間にはエンジンマウントとしての防振装置が配設されており、この防振装置はエンジンが発生する振動を吸収し、車体側への振動伝達を抑制する。このような防振装置としては、例えば、防振装置の内部に弾性体及び一対の液室を設けると共に、オリフィスとなる制限通路でこれらの液室を互いに連通した液体封入式のものが知られている。液体封入式の防振装置によれば、搭載されたエンジンが作動して振動が発生した場合には、弾性体の制振機能及び、一対の液室間を連通するオリフィス内の液体の粘性抵抗等で振動を吸収し、車体側への振動伝達を抑制する（例えば、特許文献１参照）。   For example, an anti-vibration device as an engine mount is disposed between an engine that is a vibration generation unit of a vehicle and a vehicle body that is a vibration receiving unit, and the anti-vibration device absorbs vibration generated by the engine, Suppresses vibration transmission to the vehicle body. As such an anti-vibration device, for example, an elastic body and a pair of liquid chambers are provided inside the anti-vibration device, and a liquid-filled type in which these liquid chambers communicate with each other through a restriction passage serving as an orifice is known. ing. According to the liquid-filled vibration isolator, when vibration is generated due to operation of the mounted engine, the vibration damping function of the elastic body and the viscous resistance of the liquid in the orifice communicating between the pair of liquid chambers The vibration is absorbed by, for example, and vibration transmission to the vehicle body side is suppressed (see, for example, Patent Document 1).

ところで、特許文献１に記載の防振装置には、曲げ加工で簡易に製造されるエンジンマウントブラケットが開示されている。このエンジンマウントブラケットは、液封型弾性体の軸方向上側を覆う構成を有しており、ストッパとしての機能も有している。ストッパ機能を有するブラケットは、衝突による荷重を受けるため、強度が要求される。しかしながら、曲げ加工のみで製造されたブラケットは、絞り加工によりリブ袋状部分を有する部材と比較して、強度が低い。
このような強度の低いブラケットは、常用領域（４００〜１０００Ｈｚ）で共振を起こし、振動伝達特性に影響を起こす場合がある。 By the way, the vibration isolator described in Patent Document 1 discloses an engine mount bracket that is easily manufactured by bending. This engine mount bracket has a structure that covers the upper side in the axial direction of the liquid seal type elastic body, and also has a function as a stopper. Since the bracket having the stopper function receives a load caused by a collision, the bracket is required to be strong. However, the bracket manufactured only by the bending process has low strength as compared with the member having the rib bag-like portion by the drawing process.
Such a low-strength bracket may resonate in the normal range (400 to 1000 Hz) and affect vibration transmission characteristics.

特開平８−１７７９５５JP-A-8-177955

It is to provide a vibration isolator.

上記目的を達成するため、本発明の請求項１に係る防振装置用ブラケットは、振動発生部及び振動受部の一方に連結される筒状の外側取付部材と、振動発生部及び振動受部の他方に連結され前記外側取付部材の筒軸方向からみて前記外側取付部材の内側に配置される内側取付部材と、前記内側取付部材と前記外側取付部材の間に配置されて両者を連結する弾性体と、を有する防振装置本体を支持する防振装置用ブラケットであって、前記筒軸方向で互いに向き合い前記内側取付部材の前記筒軸方向の移動を当接により規制する一対のストッパ板面部と、前記一対のストッパ板面部同士を連結するように前記ストッパ板面部の間に互いに向き合うように配置される一対の側面板部と、含んで筒状に一体的に形成され、前記外側取付部材側に固定されたストッパ部材と、前記ストッパ部材の前記一対の側面板部同士を連結すると共に、前記ストッパ板面部の少なくとも一方と前記一対の側面板部の各々の間に構成される被補強角部に固定され、前記ストッパ部材の筒軸に沿ったストッパ軸方向からみて、前記ストッパ部材の筒内空間の少なくとも一部を覆うように配置された補強部材と、前記振動発生部及び振動受部の一方に固定され、前記外側取付部材と前記振動発生部及び振動受部の一方とを連結する脚部材と、を備えている。   To achieve the above object, a vibration isolator bracket according to claim 1 of the present invention includes a cylindrical outer mounting member coupled to one of a vibration generating portion and a vibration receiving portion, a vibration generating portion, and a vibration receiving portion. An inner mounting member that is connected to the other of the outer mounting member and disposed inside the outer mounting member when viewed from the cylinder axis direction of the outer mounting member, and an elasticity that is disposed between the inner mounting member and the outer mounting member and connects the two. A pair of stopper plate surface portions that support each other in the cylinder axis direction and restrict movement of the inner mounting member in the cylinder axis direction by contact with each other And a pair of side plate portions disposed so as to face each other between the stopper plate surface portions so as to connect the pair of stopper plate surface portions to each other. Fixed to the side The stopper member and the pair of side plate portions of the stopper member are connected to each other, and fixed to a corner to be reinforced configured between at least one of the stopper plate surface portions and each of the pair of side plate portions. And a reinforcing member disposed so as to cover at least a part of the in-cylinder space of the stopper member as viewed from the stopper axis direction along the cylinder axis of the stopper member, and one of the vibration generating unit and the vibration receiving unit. A leg member that is fixed and connects the outer mounting member and one of the vibration generating portion and the vibration receiving portion;

上記構成の防振装置用ブラケットでは、振動入力による弾性体の弾性変形により、内側取付部材と外側取付部材とが所定量以上相対移動すると、ストッパ部材のストッパ板面部に当接されることにより内側取付部材の筒軸方向の移動が規制される。ストッパ板面部へ当接される部材は、内側取付部材自体であってもよいし、内側取付部材に固定された別部材であってもよい。   In the vibration isolator bracket having the above-described configuration, when the inner mounting member and the outer mounting member move relative to each other by a predetermined amount due to elastic deformation of the elastic body due to vibration input, the inner side is brought into contact with the stopper plate surface portion of the stopper member. The movement of the mounting member in the cylinder axis direction is restricted. The member brought into contact with the stopper plate surface portion may be the inner mounting member itself or another member fixed to the inner mounting member.

本発明のストッパ部材は、筒状に形成されているため、曲げ加工により簡易に形成することができる。一方、ストッパ部材には、当該当接時における衝撃荷重を受けるため、強度が求められる。特に、ストッパ部材の筒状が倒れるような変形が生じないように強度を出す必要がある。そこで、本発明では、補強部材を用いてストッパ部材の強度を補強している。補強部材は、一対の側面板部同士を連結すると共に、ストッパ板面部の少なくとも一方と一対の側面板部の各々の間に構成される被補強角部に固定されている。そして、ストッパ部材の筒軸に沿ったストッパ軸方向からみて、ストッパ部材の筒内空間の少なくとも一部を覆うように配置されている。このように、補強部材を設けることにより、ストッパ部材の筒状が倒れ込む変形を抑制することができると共に、一対の側面板部同士の連結が強化されて筒状が偏平となるような変形も抑制することができる。   Since the stopper member of the present invention is formed in a cylindrical shape, it can be easily formed by bending. On the other hand, since the stopper member receives an impact load at the time of the contact, strength is required. In particular, it is necessary to increase the strength so that the stopper member does not deform so as to collapse. Therefore, in the present invention, the strength of the stopper member is reinforced using the reinforcing member. The reinforcing member connects the pair of side plate portions to each other, and is fixed to a reinforced corner portion formed between at least one of the stopper plate surface portions and each of the pair of side plate portions. And it is arrange | positioned so that at least one part of the in-cylinder space of a stopper member may be covered seeing from the stopper axial direction along the cylinder shaft of a stopper member.

次に、本実施形態に係る防振装置１０の作用を説明する。   Next, the operation of the vibration isolator 10 according to this embodiment will be described.

防振装置１０では、エンジン又は車体側から振動が入力されると、吸振主体である弾性体１８が弾性変形する。この弾性変形により、入力された振動が、減衰吸収される。   In the vibration isolator 10, when vibration is input from the engine or the vehicle body side, the elastic body 18 which is the main vibration absorber is elastically deformed. Due to this elastic deformation, the input vibration is attenuated and absorbed.

また防振装置１０では、エンジンから比較的低い周波数域の振動、例えばシェイク振動等が入力されると、弾性体１８の弾性変形により主液室３４の内容積が拡縮し、この主液室３４の拡縮に伴って、主液室３４と副液室３６との間で、液体がオリフィス２２を通して相互に流通する。このとき、オリフィス２２内で液柱共振が生じ、この液柱共振等により、防振効果、制振効果を得ることができる。   Further, in the vibration isolator 10, when vibration in a relatively low frequency range, such as shake vibration, is input from the engine, the internal volume of the main liquid chamber 34 expands and contracts due to elastic deformation of the elastic body 18. With the expansion / contraction, the liquid flows between the main liquid chamber 34 and the sub liquid chamber 36 through the orifice 22. At this time, a liquid column resonance occurs in the orifice 22, and a vibration isolation effect and a vibration suppression effect can be obtained by the liquid column resonance or the like.

一方、エンジンから比較的高い周波数域の振動、例えばアイドル振動等が入力されると、オリフィス２２に目詰まりが発生する。この時には、メンブラン２４が、主液室３４内の容積を拡縮するように弾性変形する。これにより、主液室３４内の液圧上昇が抑制され、動的ばね定数の上昇を抑制できるので、高い周波数域の振動も効果的に吸収することができる。   On the other hand, when vibration in a relatively high frequency range, such as idle vibration, is input from the engine, the orifice 22 is clogged. At this time, the membrane 24 is elastically deformed so as to expand and contract the volume in the main liquid chamber 34. As a result, an increase in the hydraulic pressure in the main liquid chamber 34 is suppressed and an increase in the dynamic spring constant can be suppressed, so that vibrations in a high frequency range can also be effectively absorbed.

また、エンジンまたは車体から大振幅の振動が入力した場合には、図５に示すように、ストッパアーム５０の下ゴム部５４Ｂがストッパ板面部４１Ｂに当たり、ストッパアーム５０と外側取付部材１６との間の相対移動が規制される。続いて、ストッパアーム５０は、リバウンドにより、図５の二点鎖線で示すように、上ゴム部５４Ａがストッパ板面部４１Ａに当たり、ストッパアーム５０と外側取付部材１６との間の相対移動が規制される。   When a large amplitude vibration is input from the engine or the vehicle body, the lower rubber portion 54B of the stopper arm 50 hits the stopper plate surface portion 41B as shown in FIG. Relative movement is restricted. Subsequently, as shown by a two-dot chain line in FIG. 5, the stopper arm 50 is rebounded so that the upper rubber portion 54 </ b> A hits the stopper plate surface portion 41 </ b> A and relative movement between the stopper arm 50 and the outer mounting member 16 is restricted. The

このとき、ストッパ部材４２に大きな衝撃が加わった場合でも、補強部材６０によりストッパ部材４２が補強されているので、曲げ加工により形成されたストッパ部材４２の変形を抑制することができる。   At this time, even when a large impact is applied to the stopper member 42, since the stopper member 42 is reinforced by the reinforcing member 60, the deformation of the stopper member 42 formed by bending can be suppressed.

なお、本実施形態では、補強本体部６２の外周に張出部６２Ｆを形成したが、張出部６２Ｆは必ずしも必要ではなく、補強本体部６２の外周縁がストッパ部材４２の端面に配置されていてもよい。本実施形態では、張出部６２Ｆを形成しているので、ストッパ部材４２の強度をより高くすることができる。   In this embodiment, the overhang 62F is formed on the outer periphery of the reinforcing main body 62. However, the overhang 62F is not always necessary, and the outer peripheral edge of the reinforcing main body 62 is disposed on the end surface of the stopper member 42. May be. In this embodiment, since the overhang | projection part 62F is formed, the intensity | strength of the stopper member 42 can be made higher.

また、本実施形態では、補強部材６０がステー連結部６４を有し、補強本体部６２とステー連結部６４を一体的に形成した例について説明したが、ステー連結部６４は別体としてもよい。本実施形態のように、補強本体部６２とステー連結部６４を一体的に形成することにより、補強部材６０がストッパ部材４２の補強機能と車体への連結機能を兼ね備えることができ、部品点数を増加させることなく、ストッパ部材４２の補強を行うことができる。   In the present embodiment, the example in which the reinforcing member 60 has the stay connecting portion 64 and the reinforcing main body portion 62 and the stay connecting portion 64 are integrally formed has been described. However, the stay connecting portion 64 may be a separate body. . By integrally forming the reinforcing main body 62 and the stay connecting portion 64 as in this embodiment, the reinforcing member 60 can have both the reinforcing function of the stopper member 42 and the connecting function to the vehicle body, and the number of parts can be reduced. The stopper member 42 can be reinforced without increasing it.

また、本実施形態では、補強部材６０の補強本体部６２をストッパ部材４２の端面に固定したが、必ずしも端面に固定する必要はなく、図６に示すように、筒内に補強本体部６２を固定してもよい。この場合には、補強本体部６２の外周端面をストッパ部材４２の内周面に溶接する。   In this embodiment, the reinforcing main body 62 of the reinforcing member 60 is fixed to the end surface of the stopper member 42. However, the reinforcing main body 62 is not necessarily fixed to the end surface, and as shown in FIG. It may be fixed. In this case, the outer peripheral end surface of the reinforcing main body 62 is welded to the inner peripheral surface of the stopper member 42.

また、本実施形態では、補強本体部６２は、板面をストッパ部材４２の突出部４１Ｃが形成されている側の開口（筒内空間）の略上半分（ストッパ板面部４１Ａ側）を覆うように配置したが、図７に示すように、板面をストッパ部材４２の突出部４１Ｃが形成されている側の開口（筒内空間）の略下半分（ストッパ板面部４１Ｂ側）が覆われるように配置してもよい。   Further, in the present embodiment, the reinforcing main body 62 covers the plate surface to cover the substantially upper half (the stopper plate surface portion 41A side) of the opening (in-cylinder space) on the side where the protruding portion 41C of the stopper member 42 is formed. However, as shown in FIG. 7, the plate surface is covered with the substantially lower half (stopper plate surface portion 41B side) of the opening (in-cylinder space) on the side where the protruding portion 41C of the stopper member 42 is formed. You may arrange in.
