【考案の詳細な説明】
従来、自動車の排気管をボディに取付ける方法としては
、例えば第１図に示す様にＯリング１をボディ２と排気
管３の各フック４，５に係止して排気管を吊持させてい
る。[Detailed description of the invention] Conventionally, as a method for attaching an automobile exhaust pipe to the body, for example, as shown in FIG. The exhaust pipe is suspended.
この方法ではリングの引っ張り方向のバネレートが高い
から排気管の下方向の動きに対しては拘束力があるもの
の、左右方向・上下方向の動きは殆ど規制できない。In this method, since the spring rate of the ring in the tension direction is high, there is a restraining force against the downward movement of the exhaust pipe, but movement in the horizontal and vertical directions can hardly be restricted.
このため、悪路走行時、急カーブ時等の大挙動時に排気
管がフロアやその他のものに当接し、金属打音・雑音が
生じる。For this reason, when driving on a rough road or making a sharp turn, the exhaust pipe comes into contact with the floor or other objects, producing metal banging and noise.
また従来における他の例としては、第２図に示す様にボ
ディ２側の取付ブラケット６と排気管３側のブラケット

ション性を有する構造のものもあるが、これではゴム８
が大挙動時の振動、衝撃を吸収できる硬質のバネレート
の高いものとなり、アイドリング時及び平常走行時に微
振動が排気管からゴムを介してフロアに伝達される。In addition, as another conventional example, as shown in FIG. 2, a mounting bracket 6 on the body 2 side and a bracket 7 on the exhaust pipe 3 side are vulcanized and bonded via elastic rubber 8 to provide cushioning properties. There is also a structure, but this one has a rubber 8
It has a hard spring rate that can absorb vibrations and shocks during large movements, and slight vibrations are transmitted from the exhaust pipe to the floor through the rubber during idling and normal driving.
また、今日の排気ガス対策により排気管に高温の排気ガ
スが流れ、排気管の管軸方向の熱伸縮量が大となると、
これを吸収できない。Furthermore, due to today's exhaust gas countermeasures, high-temperature exhaust gas flows into the exhaust pipe, and the amount of thermal expansion and contraction in the axial direction of the exhaust pipe becomes large.
I can't absorb this.
更に、排気管からゴム接着部に高温が伝わり、ゴム接着
部が剥離する虞れがあった。Furthermore, there was a risk that high temperature would be transmitted from the exhaust pipe to the rubber bonded portion, causing the rubber bonded portion to peel off.
そこで、排気管を車体に対して摺動自在に支持し、これ
により熱伸縮を吸収するものが一部に提案されているが
、振動の吸収性が悪いと共に、円滑に摺動しない時の不
具合があり、実用化には至っていない。Therefore, some proposals have been made to support the exhaust pipe in a slidable manner relative to the vehicle body, thereby absorbing thermal expansion and contraction, but this has poor vibration absorption properties and causes problems when it does not slide smoothly. However, it has not yet been put into practical use.
本考案は上記の点に鑑みこれを改良したものであって、
その横取を図面にもとづいて説明すると次の通りである
。The present invention is an improvement on the above points,
The usurpation is explained as follows based on the drawing.

挿されているから、次のような作用効果がある。As explained above, this invention is an exhaust pipe support device that supports an exhaust pipe on a vehicle body via an elastic suspension made of an elastic material such as rubber, and the elastic suspension includes a It has three parts, a part and a lower part, in which a plurality of through holes are provided in the upper part in parallel with the exhaust pipe, a gap part is provided in the central part, and at the boundary between the central part and the lower part, Further, downward stopper portions are integrally formed on both sides of the lower surface of the central portion, and both upper side surfaces of a bracket for connecting to the exhaust pipe are integrally hung and suspended at the center of the lower portion. The body is
A base that tightly surrounds the upper surface and both sides of the upper part, and a base that extends from both sides of the base to below the boundary between the center and lower part of the elastic suspension, and that extends on both sides of the center of the elastic suspension. On the other hand, skirt parts on both sides are opposed to each other with an appropriate gap in the lateral direction of the exhaust pipe, and the lower ends of the skirt parts are bent inward to maintain a predetermined gap in the vertical direction with the stopper part of the elastic suspension body. The guide rod, which is attached to the vehicle body in parallel with the exhaust pipe, is slidably inserted into the through hole of the elastic suspension body, which is surrounded by an outer frame that is open at the bottom and consists of opposing locking parts. Because of this, it has the following effects.
先ず、弾性吊持体は、上部、中央部、下部の３部分で構
威し、上部をガイド棒挿通部として上面と両側面を外枠
の基部に密着包囲させである。First, the elastic suspension body consists of three parts: an upper part, a central part, and a lower part, and the upper part is used as a guide rod insertion part, and the upper surface and both sides are closely surrounded by the base of the outer frame.
これによって、弾性吊持体のガイド棒挿通部に形成され
た貫通孔は、変形から保護され、ガイド棒にコゼ等を与
えないため、カラー等を使用しなくても、弾性吊持体の
ガイド棒上での前後方向への摺動を円滑に保持させ得る
。As a result, the through hole formed in the guide rod insertion part of the elastic suspension body is protected from deformation and the guide rod is not curled, so it is possible to guide the elastic suspension body without using a collar or the like. Smooth sliding in the front and rear directions on the rod can be maintained.
また、弾性吊持体の上部を除く中央部と下部とは、外枠
との開枠の範囲内で、上下、左右、前後に自由に弾性変
形でき、アイドリング運転時や通常走行時等に生じる排
気管の比較的軽微な振動を、上記自由変形領域内での弾
性変形によって吸収緩和させ、車体に伝達させない。In addition, the center and lower parts of the elastic suspension body, excluding the upper part, can be freely elastically deformed up and down, left and right, and front and back within the range of the open frame with the outer frame, which may occur during idling or normal driving. Relatively slight vibrations of the exhaust pipe are absorbed and relaxed by elastic deformation within the free deformation region, and are not transmitted to the vehicle body.
特に、弾性吊持体の中央部には空隙が設けであるため、
バネレートが低く（柔軟）、下部中央に挾持垂設される
ブラケットを介して伝達される排気管の振動変位は、弾
性吊持体の中央部の弾性変形により柔軟に吸収緩和され
る。In particular, since there is a gap in the center of the elastic suspension body,
The vibration displacement of the exhaust pipe, which has a low spring rate (flexibility) and is transmitted through the bracket that is suspended and suspended at the center of the lower part, is flexibly absorbed and alleviated by the elastic deformation of the central part of the elastic suspension body.
そして、悪路走行時等の排気管の上下方向の過大変位は
、弾性吊持体の中央部の空隙が圧迫されて上方への過大
変位を弾性材同志の当接により防止し、下方への過大変
位は弾性吊持体のストッパ部が外枠の係止部に当接する
ことにより防止し、弾性吊持体に上下方向の過大変位に
よる亀裂破損が生ずることを、弾性材の当接による衝撃
の吸収緩和作用と、衝突異音の発生抑制作用とによって
静穏かつ無衝撃で防止させることができる。When the exhaust pipe is excessively displaced in the vertical direction when driving on rough roads, the air gap in the center of the elastic suspension member is compressed, and excessive upward displacement is prevented by contact between the elastic members, and the downward movement is prevented. Excessive displacement of the elastic material is prevented by the stopper part of the elastic suspension body coming into contact with the locking part of the outer frame. The impact can be prevented quietly and without impact by absorbing and alleviating the impact caused by contact and suppressing the occurrence of abnormal collision noise.
同様に、急カーブ時等のような排気管の過大な横振れ変
位は、弾性吊持体の中央部両側面が外枠のスカート部内
面に当接することで防止され、この場合も、外枠へ弾性
材が当接するため、衝撃の吸収緩和作用と、衝突異音の
発生抑制作用とによって静穏かつ無衝撃で弾性吊持体の
亀裂発生等が防止される。Similarly, excessive lateral displacement of the exhaust pipe, such as when making a sharp turn, is prevented by the both sides of the central part of the elastic suspension body coming into contact with the inner surface of the skirt part of the outer frame. Since the elastic material comes into contact with the elastic member, cracks and the like in the elastic suspension body are prevented from occurring in a quiet and non-impact manner by absorbing and mitigating the impact and suppressing the occurrence of abnormal collision noise.
特に、排気管の上下及び左右方向の過大変位による弾性
吊持体の外枠への衝撃は、弾性吊持体自身の弾性吸収作

付けたものでなく、弾性吊持体の上部の貫通孔にガイド
棒を挿通して車体に対し、さらに弾性材を介在させた状
態で間接的に支持させであることによって、車体への衝
撃の伝達が一層軽微となる。In particular, the impact on the outer frame of the elastic suspension body due to excessive vertical and horizontal displacement of the exhaust pipe is not only alleviated by the elastic absorption action of the elastic suspension body itself, but also the outer frame itself is By inserting a guide rod into the through hole at the top of the elastic suspension body and indirectly supporting the car body with an elastic material interposed, the shock to the car body can be reduced. The transmission of information becomes even more subtle.
また、急停止や急発進等のような排気管の軸方向の過大
変位も、弾性吊持体がガイド棒上で摺動することで静穏
かつ、無衝撃的に吸収でき、更に、排気管の温度変化に
よる軸方向の膨張・伸縮を弾性吊持体をガイド棒上で摺
動させることで吸収させることができる。In addition, excessive displacement in the axial direction of the exhaust pipe due to sudden stops or sudden starts can be absorbed quietly and without impact by the elastic suspension body sliding on the guide rod. Expansion and contraction in the axial direction due to temperature changes can be absorbed by sliding the elastic suspension body on the guide rod.
更に、また、外枠の下方を開放したから、弾性吊持体か
らブラケットを真下に延長して設けることができ、排気
管を接続するためのブラケットが小型になると共に弾性
吊持体と外枠との組付が容易になる。Furthermore, since the lower part of the outer frame is open, it is possible to extend the bracket directly below from the elastic suspension member, and the bracket for connecting the exhaust pipe becomes smaller, and the elastic suspension member and outer frame Easy to assemble with.
要するに、外枠の下方を開放したから、排気管支持装置
の構造が小型で簡単となり、安価で、かつ、組付作業性
が向上する等の効果がある。In short, since the lower part of the outer frame is opened, the structure of the exhaust pipe support device is small and simple, and it is inexpensive, and the assembly workability is improved.
