【考案の詳細な説明】
本考案は、例えばエンジンのオイルパンを遮音カバーに
よって覆う遮音構造に使用する遮音用シール部材に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sound insulating seal member used, for example, in a sound insulating structure that covers an engine oil pan with a sound insulating cover.
一般にエンジンのオイルパンはシリンダボデーの下端に
シール部材を介して取付けられているが、シリンダボデ
ーの振動が伝達して大きな騒音を発し、エンジンの主要
騒音源の一つになっていた。Generally, the oil pan of an engine is attached to the lower end of the cylinder body via a sealing member, but the vibration of the cylinder body is transmitted and generates a large amount of noise, making it one of the main noise sources of the engine.
そこでオイルパンの外周を遮音カバによって被覆するこ
とが提案されているが、従来のカバーではシール機能が
不完全で、十分なる遮音効果を得ることができなかった
。Therefore, it has been proposed to cover the outer periphery of the oil pan with a sound insulating cover, but the conventional cover has an incomplete sealing function and cannot provide a sufficient sound insulating effect.
本考案は上記のような従来の遮音カバーの欠点を除去す
るための遮音用シール部材であり、例えばオイルパンか
らの放射音及びオイルパンから遮音カバーへの振動伝播
をきわめて効果的に遮音することができると共に、取付
作業性に優れた遮音用シール部材を提供するものである
。The present invention is a sound insulating seal member that eliminates the drawbacks of the conventional sound insulating cover as described above. It is an object of the present invention to provide a sound insulating seal member which is capable of providing excellent installation workability.
以下にその実施例を図面の第１図及び第２図に従って説
明する。The embodiment will be described below with reference to FIGS. 1 and 2 of the drawings.
１はエンジンのオイルパンでシリンダボデー２の下端に
配設されている。Reference numeral 1 denotes an oil pan of the engine, which is disposed at the lower end of the cylinder body 2.
オイルパンにはその外形形状に対応しその適宜の空隙Ｓ
を設けて遮音カバー３が取付けられている。The oil pan has an appropriate gap S corresponding to its external shape.
A sound insulating cover 3 is attached to the sound insulating cover 3.
４は本案のシール部材で、無端状の弾性材料から戊り、
シール部材本体４ａの中央部に嵌合凹部４１を形威し、
且つその側方にくの字状の伸延する第一リップ４２及び
第二リップ４３を設けて構威し、上記嵌合凹部４１をも
って上記遮音カバー３の上端３１に嵌着せしめ、上記第
一リップ４２、第二リップ４３をもってオイルパン１の
外側周辺に弾性的に当接せしめることができるものであ
る。4 is the sealing member of the present invention, which is hollowed out of an endless elastic material;
A fitting recess 41 is formed in the center of the seal member main body 4a,
Further, a first lip 42 and a second lip 43 extending in a dogleg shape are provided on the sides thereof, and the fitting recess 41 is fitted into the upper end 31 of the sound insulation cover 3, and the first lip 42, the second lip 43 can be brought into elastic contact with the outer periphery of the oil pan 1.
遮音カバー３を支持するための下部ブラケット５は遮音
カバーの外側部に適宜個数取付けられていて、オイルパ
ン１のフランジ１１と共にボルト６によってシリンダボ
デー２に支持された上部ブラケット７に弾性支持部材、
例えばゴム部材８，９を介在せしめてボルト２０によっ
て取付けられている。An appropriate number of lower brackets 5 for supporting the sound insulation cover 3 are attached to the outer side of the sound insulation cover, and an elastic support member is attached to the upper bracket 7 supported on the cylinder body 2 by bolts 6 together with the flange 11 of the oil pan 1.
For example, they are attached by bolts 20 with rubber members 8 and 9 interposed therebetween.
本考案によるシール部材は以上のように構成しているの
で、これを上記のように用いるときはオイルパン１から
遮音カバーへの振動伝播は遮音用シール部材４と空隙Ｓ
とによって完全に遮断されると共に、オイルパン１の外
表面１２から放射音が空隙Ｓより洩れんとしても、上記
シール部材４の第一リップ４２、第二リップ４３によっ
て上記空隙Ｓの上端が２重に封止されているため、上述
のような放射音の漏洩もより確実に防止される。Since the seal member according to the present invention is constructed as described above, when this is used as described above, the vibration propagation from the oil pan 1 to the sound insulation cover is caused by the sound insulation seal member 4 and the air gap S.
Even if the sound radiated from the outer surface 12 of the oil pan 1 does not leak from the gap S, the upper end of the gap S is blocked by the first lip 42 and the second lip 43 of the seal member 4. Since it is heavily sealed, leakage of the radiated sound as described above is more reliably prevented.
更に本考案による２つのリップは前述のように構成され
ているので、シール部材４は全体としての剛性を確保し
ながら比較的やわらかい弾性部材を用いることができ、
前記実施例の場合オイルパン１から遮音カバー３への振
動の伝達を著しく減少させると共に、その減衰効果をも
高めることができる。Furthermore, since the two lips according to the present invention are constructed as described above, the sealing member 4 can be made of a relatively soft elastic member while ensuring overall rigidity.
In the case of the embodiment described above, the transmission of vibrations from the oil pan 1 to the sound insulating cover 3 can be significantly reduced, and the damping effect thereof can also be enhanced.
これによりシール部材４は、遮音カバ−３上端全周に嵌
合させるだけで、即ち無端状のものを１個使用するだけ
で、オイルパン１からの音の洩れおよび伝達を十分抑制
することが可能である。As a result, the seal member 4 can sufficiently suppress leakage and transmission of sound from the oil pan 1 by simply fitting the seal member 4 around the entire upper end of the sound insulating cover 3, that is, by using only one endless seal member. It is possible.
更に本考案の他の効果を前記実施例で説明すると、シー
ル部材４はその嵌合凹部４１が遮音部材３の上端に嵌合
することにより保持されているので、遮音カバー３への
シール部材４の取付作業のみならず、同シール部材４を
上端に保持した状態で遮音カバー３をオイルパン１に取
り付ける作業が容易である。Further, another effect of the present invention will be explained with reference to the above embodiment. Since the sealing member 4 is held by fitting the fitting recess 41 into the upper end of the sound insulating member 3, the sealing member 4 is not attached to the sound insulating cover 3. It is easy not only to attach the sound insulating cover 3 to the oil pan 1 while holding the seal member 4 at the upper end.
即ち、取付のため遮音カバーをオイルパン１に、シール
部材４側から挿入する際、特に２つのリップ４２と４３
、特に下方のリップ４３の働きで、遮音カバー３のオイ
ルパン１に対する位置ずれ（位置の片寄り）が防止され
るので、はＳ゛均等空隙が保持された状態で所定位置に
挿入でき、遮音カバー３のシリンダーボデー２への取付
がきわめて正確、容易となる。That is, when inserting the sound insulation cover into the oil pan 1 from the sealing member 4 side for installation, especially the two lips 42 and 43
In particular, the function of the lower lip 43 prevents the sound insulation cover 3 from shifting relative to the oil pan 1 (shifting of the position), so that the sound insulation cover 3 can be inserted into a predetermined position while maintaining an even gap, and the sound insulation cover 3 is The attachment of the cover 3 to the cylinder body 2 becomes extremely accurate and easy.
しかも挿入方向がシール部材４が遮音カバー３上端によ
り強く嵌合する方向であることもシール部材の外れ防止
上有利である。Furthermore, it is also advantageous for the insertion direction to be a direction in which the seal member 4 is more firmly fitted to the upper end of the sound insulating cover 3 in order to prevent the seal member from coming off.
リップ４３のない場合、横方向の剛性が弱く、前記位置
ずれが生じた状態のまま取付けられる可能性が高い。If there is no lip 43, the rigidity in the lateral direction is weak, and there is a high possibility that it will be installed with the positional deviation as described above.
取り付は状態で空隙Ｓに片寄りが生ずると、遮音カバー
３のシリンダーボデー２への取付部に位置ずれが生じ、
位置合せをしなければならず、作業性が悪化するのみな
らず、遮音カバー３がオイルパン１へ直接接触すること
もあり、かえって異音の発生を招くのである。During installation, if the gap S is biased, the mounting portion of the sound insulating cover 3 to the cylinder body 2 will be misaligned.
This requires alignment, which not only impairs work efficiency, but also causes the sound insulating cover 3 to come into direct contact with the oil pan 1, which may even cause abnormal noise.
また挿入時の前記位置ずれにより、シール部材４が遮音
カバー上端から外れることもあり、この修正をしながら
の作業はきわめて能率が悪い。Furthermore, due to the positional deviation during insertion, the sealing member 4 may come off the upper end of the sound insulating cover, and it is extremely inefficient to work while making corrections.
これに対し本考案による遮音用シール部材は、第一のリ

いった不具合を完全に解消することができ、しかもシー
ル機能を確保し、遮音すべき部材からの音の洩れと伝達
をきわめて効果的に防ぐことができるものである。On the other hand, the sound insulation seal member according to the present invention has the above-mentioned second lip in addition to the first lip, so it completely eliminates the problems such as the occurrence of abnormal noise due to the positional deviation and the deterioration of installation workability. Moreover, the sealing function can be ensured, and the leakage and transmission of sound from the member to be sound-insulated can be extremely effectively prevented.
また、前記実施例ではシリンダボデー２より弾性支持部
材を介して遮音カバー３に振動が伝播されることもない
。Furthermore, in the embodiment described above, vibrations are not transmitted from the cylinder body 2 to the sound insulating cover 3 via the elastic support member.

かも取付作業性に優れたものである。As described above, the sound insulating seal member according to the present invention can very effectively insulate, for example, the sound radiated from the oil pan and the vibration propagation from the oil pan to the sound insulating cover, and has excellent installation workability. .
