本考案はエンジンのクランクケース下端にオイルパンを
弾性的に装着し、オイルパンから発生する騒音を防止す
るための支持装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for elastically mounting an oil pan on the lower end of an engine crankcase to prevent noise generated from the oil pan.
第１図によってこの種の支持装置の従来例を説明する。A conventional example of this type of support device will be explained with reference to FIG.
１はエンジンのクランクケース、２はオイルパンでその
上端にはフランジ２ａが形成されている。1 is an engine crankcase, 2 is an oil pan, and a flange 2a is formed at the upper end thereof.
このフランジ２ａの周囲には内側面にスリブ１−３を有
するゴム等の弾性部材４が嵌合され、そしてこの弾性部
材４が断面り字状のリテーナ５によりクランクケース１
の下端にボルト６で固着されている。An elastic member 4 made of rubber or the like having sleeves 1-3 on the inner surface is fitted around this flange 2a, and this elastic member 4 is attached to the crankcase 1 by a retainer 5 having an angular cross section.
It is fixed to the lower end of the body with a bolt 6.
以上のようにオイルパン２の弾性支持装置は、クランク
ケース１からの振動を弾性部材４によって遮断し、オイ
ルパン２が振動されることによって発生する騒音を防止
するものである。As described above, the elastic support device for the oil pan 2 uses the elastic member 4 to block vibrations from the crankcase 1, thereby preventing noise generated when the oil pan 2 is vibrated.
しかしながら、弾性部材４は振動の伝達を防止するとと
もに密封性を確保する必要がある。However, the elastic member 4 needs to prevent transmission of vibrations and ensure sealing performance.
振動の伝達は弾性部材の変形による剛性を低下させれば
良いが、剛性を低下させるためシール面４ａの間隔１を
大きくすると面圧が低下し、オイルが洩れてしまうこと
になる。Transmission of vibrations can be achieved by reducing the rigidity due to deformation of the elastic member, but if the interval 1 between the seal surfaces 4a is increased in order to reduce the rigidity, the surface pressure will decrease and oil will leak.
また逆に密封性を向上するためシール面の面圧を上昇さ
せると、弾性部材の内部変形量が大きくなり、剛性が上
がってしまい振動の減衰効果が低下することになる。On the other hand, if the surface pressure of the sealing surface is increased in order to improve the sealing performance, the amount of internal deformation of the elastic member will increase, the rigidity will increase, and the vibration damping effect will decrease.
したがって、上述のような支持装置にあってもクランク
ケース１からの振動は十分に遮断し切れない欠点を有し
ていた。Therefore, even with the above-mentioned support device, vibrations from the crankcase 1 cannot be sufficiently isolated.
ところで、オイルパン２から発生する騒音は、その側面
２ｂが矢印に示す左右方向に振動されて発生するもので
、これは、リテーナ５の側面５ａからの振動が弾性部材
４内を通過し、フランジ２ａの端部に伝達されて、オイ
ルパン２の側面２ｂに左右方向の振動を与えることによ
るものであることがわかった。By the way, the noise generated from the oil pan 2 is caused by the side surfaces 2b of the oil pan being vibrated in the left and right directions shown by the arrows. It has been found that this is due to vibrations being transmitted to the ends of oil pan 2a and imparting horizontal vibrations to side surfaces 2b of oil pan 2.
本考案は上述の点より考えられたもので、密封性を低下
させることなく、クランクケースがらオイルパンへの振
動の伝達を遮断するオイルパンの弾性支持装置を提供す
ることを目的とし、その要旨はオイルパンの７ランジが
嵌合する弾性部材の溝内に拡大中空部を形成し、該オイ
ルパンのフランジ端部が該拡大中空部にあるようにした
ことにある。The present invention was conceived in view of the above points, and its purpose is to provide an elastic support device for an oil pan that blocks transmission of vibration from the crankcase to the oil pan without reducing sealing performance. An enlarged hollow part is formed in the groove of the elastic member into which the seven flanges of the oil pan fit, and the flange end of the oil pan is located in the enlarged hollow part.
以下図示の一実施例について説明する。An example illustrated in the drawings will be described below.
第２図において、７は一体構造の弾性部材４のスリット
３に連続して形成された拡大中空部でオイルパン２つの
フランジ２ａの全周に互って形成されている。In FIG. 2, reference numeral 7 denotes an enlarged hollow portion formed continuously with the slit 3 of the elastic member 4 having an integral structure, and is formed alternately around the entire circumference of the flanges 2a of the two oil pans.
８，９は弾性部材４のシール面４ａと外周面に設けられ
た凹部である。8 and 9 are recesses provided on the sealing surface 4a and the outer peripheral surface of the elastic member 4.
１０は弾性部材４の内周面に設けられたリブでオイルパ
ン２の側面に当接させることによりオイルパンの左右方
向の位置決めを行う。Reference numeral 10 denotes a rib provided on the inner peripheral surface of the elastic member 4, which positions the oil pan in the left-right direction by bringing it into contact with the side surface of the oil pan 2.
また、拡大中空部７と凹部８，９によって形成された弾
性部材４の薄肉部４ｂは外側方向の位置決めを行うもの
である。Further, the thin portion 4b of the elastic member 4 formed by the enlarged hollow portion 7 and the recesses 8 and 9 is used for positioning in the outward direction.
尚、上記実施例では弾性部材４に拡大中空部７、凹部８
，９を設けたが、第３図に示す如く、拡大中空部７′の
みとすることもできる。In the above embodiment, the elastic member 4 has an enlarged hollow part 7 and a recessed part 8.
, 9 are provided, but it is also possible to provide only the enlarged hollow portion 7' as shown in FIG.
本考案は以上のように構成したので、弾性部材の左右方
向のばね定数が小さくなり同方向の振動減衰効果が大き
くなる。Since the present invention is constructed as described above, the spring constant of the elastic member in the left-right direction becomes small, and the vibration damping effect in the same direction becomes large.
即ち、オイルパンフランジの端部はスリットより、これ
に通ずる拡大中空部に弾性部材に接することなくあるよ
うにしたので、クランクケースの左右方向の振動に伴う
リテーナ側面からの振動は、オイルパンフランジの端部
に直接伝達されることはなく、しかもオイルパンのフラ
ンジ部は、拡大中空部の形成により、左右方向のバネ定
数の小さくなった弾性部材に支持されるので、同方向の
振動を著しく減衰させることができる。In other words, since the end of the oil pan flange is located in the enlarged hollow part leading to the slit without contacting the elastic member, vibration from the side surface of the retainer due to left-right vibration of the crankcase is absorbed by the oil pan flange. Moreover, the flange of the oil pan is supported by an elastic member with a small spring constant in the left and right directions due to the formation of an enlarged hollow part, so vibrations in the same direction are significantly reduced. It can be attenuated.
更に、中空部をもたない同一高さの弾性部材に比べ本考
案の弾性部材におけるオイルパンがら弾性部材の周囲又

クランクケースと弾性部材上面の接触面、およびオイル

方向の総合的なシール面圧は大きく変化しないので、密
封性の低下を軽減できる等の効果を有する。Furthermore, compared to an elastic member of the same height that does not have a hollow part, the elastic member of the present invention has a better sealing performance against oil leakage from the oil pan around the elastic member or through the slit.
The overall longitudinal sealing surface pressure of the contact surface between the crankcase and the upper surface of the elastic member, and the contact surface between the upper surface of the oil pan flange and the slit portion of the elastic member does not change significantly, so the reduction in sealing performance can be reduced. has.
