本考案は遮音構造としたエンジンのオイルパン
に関するものである。[Detailed Description of the Invention] The present invention relates to an engine oil pan having a sound insulating structure.
エンジンのシリンダブロツクの下部に装着され
るオイルパンは、比較的肉厚が薄く、エンジン騒
音が外部に漏れる部分の一つとなつている。 The oil pan, which is attached to the bottom of the engine's cylinder block, has a relatively thin wall and is one of the parts through which engine noise leaks to the outside.
このため、従来、第1図に縦断正面図で示した
ように、オイルパン1の側壁部2から底部3まで
の全体を、底部4aを有する遮音カバー4によつ
て覆うようにしたものがある。 For this reason, conventionally, as shown in a vertical front view in FIG. 1, there is a system in which the entire oil pan 1 from the side wall 2 to the bottom 3 is covered with a sound insulating cover 4 having a bottom 4a. .
このように、底部4aを有する遮音カバー4が

を溶接等により取付けなければならない。 In this way, in the oil pan to which the sound insulating cover 4 having the bottom portion 4a is attached, after the sound insulating cover 4 is attached, the sound insulating cover 4 is passed through an appropriate portion of the side wall portion 2 near the bottom portion 3 of the oil pan 1. Base 6 of gauge guide 5 for oil level gauge 5a
must be attached by welding, etc.
しかしながら、遮音カバー4をオイルパン1に

孔4bを通して溶接作業を行わなければならず、
その作業は極めて困難性を伴うと共にその仕上が
りも著しく不良なものにならざるを得なかつた。 However, when attaching the base 6 of the gauge guide 5 by welding or the like after the sound insulation cover 4 is attached to the oil pan 1, welding work must be performed through the through hole 4b of the sound insulation cover 4.
The work was extremely difficult and the finished product was extremely poor.

の基部を取付ける際は、前述の底部4aを有する
遮音カバー4と同様の不具合を有する。 Furthermore, in Japanese Utility Model Application Publication No. 50-126807, the lower end of the oil pan is open so that a part of the bottom of the oil pan is directly cooled by the outside air, and the sides of the oil pan are covered with soundproof plates placed with a gap between them. This disclosure discloses an oil pan for a vehicle engine that is surrounded by an oil pan, but there is no description regarding the installation of a gauge guide, and according to the embodiment, the soundproof plate extends downward to near the bottom of the oil pan. Therefore, when attaching the base of the gauge guide, there is a problem similar to that of the sound insulating cover 4 having the bottom portion 4a described above.
本考案は上述の点に鑑み、遮音カバーによるオ
イルパンからのエンジン騒音の遮断を十分に達成
しつゝ、遮音カバー及びゲージガイドの取付けを
容易にしたエンジンのオイルパンを提供するもの
である。 In view of the above-mentioned points, the present invention provides an oil pan for an engine in which the sound insulation cover sufficiently blocks engine noise from the oil pan, and the sound insulation cover and the gauge guide can be easily attached.

エンジンのオイルパンにある。 The gist is that an oil pan boss having a height less than the depth of the recess is provided in a recess formed in the side wall of the oil pan, and a gap is provided between the oil pan boss and the outer peripheral surface of the side wall. The oil pan of the engine is provided with a sound insulating cover extending downward to the vicinity of the boss, and a base of a gauge guide is attached to the oil pan boss.
つぎに、図面を参照しながら本考案の1実施例

る。 Next, one embodiment of the present invention will be described with reference to the drawings. As shown in a longitudinal sectional front view in FIG. A recess 8 is formed having a width into which the base 19 of the gauge guide 18 for the oil level gauge 18a and the oil pan boss 9 can be inserted.

13aを介して取付けられる。 The outer periphery of the side wall 2 of the oil pan 1 with the oil pan boss 9 welded into the recess 8 has a lower end facing near the installation part of the oil pan boss 9 to which the base 19 of the gauge guide 18 is attached, and an upper end. The sound insulating cover 12 has a height facing the mounting flange 13 on the cylinder block side or a position close to its reinforcing member 13a, and has sound insulating seals 14 and 15 made of an elastic material such as rubber on the upper and lower ends, respectively. It is fitted to the flange 13 of the oil pan 1 through an elastic support member 16 which is fitted with a gap from the bottom 3 directions of the pan 1 and is disposed on the outer periphery of the sound insulating cover 12 at an appropriate interval. It is attached via the reinforcing member 13a.

することにより取付けられる。 After installing the sound insulation cover 12, the base 19 of the gauge guide 18 is inserted into the oil passage 1.
The oil pan boss 9 is attached by screwing a hollow bolt 11 having a diameter of 0 and a communication hole 11a to the threaded portion 9a of the oil pan boss 9.

たオイルパンが得られる。 In the engine oil pan of the present invention constructed and assembled as described above, a sealed sound insulation space is obtained between the outer peripheral surface of the side wall portion 2 of the oil pan 1 and the sound insulation cover 12, and a sound insulation space is also provided. An oil pan is obtained in which only the bottom portion 3, where the oil 7 is always reserved, and the side wall portion 2a adjacent thereto are exposed below the vicinity of the installation portion of the oil pan boss 9 where the lower end of the cover 12 faces.

で、次のような効果がある。 As described above, in the engine oil pan according to the present invention, an oil pan boss having a height equal to or less than the depth of the recess is provided in the recess formed in the side wall of the oil pan, and the oil pan boss has a height equal to or lower than the depth of the recess. Since a sound insulating cover is provided with a gap therebetween and extends downward to the vicinity of the oil pan boss, and the base of the gauge guide is attached to the oil pan boss, the following effects can be obtained.
即ち、オイルパンボスがオイルパンの側壁部よ
り外方に突出することがないので、遮音カバーの
底部方向からの嵌合、組付けがきわめて容易に行
い得る。 That is, since the oil pan boss does not protrude outward from the side wall of the oil pan, fitting and assembling the sound insulating cover from the bottom direction can be performed extremely easily.
更に、ゲージガイドの基部の取付けは、従来の
有底4a遮音カバーと異なり、遮音カバーに設け

がある。 Furthermore, unlike the conventional bottomed 4a sound insulation cover, there is no need to install the base of the gauge guide through the opening 4b provided in the sound insulation cover.
After the sound insulating cover is installed, it can be directly attached to the side wall of the oil pan, which has the effect of making it extremely easy to attach the base of the gauge guide.

ができるなど優れた利点を有する。 In addition, noise during engine operation tends to leak from inside the oil pan 1 to the outside through the side wall 2, but the sound insulation cover 12 and sound insulation seals 14 and 15 prevent it from leaking, while the oil 7 inside the main body 1 attenuates it. Since the bottom part 3 and the side wall part 2a exposed in the vicinity of the bottom part 3 and the side wall part 2a exposed in the vicinity only leak into the outside noise as extremely small noise, the leakage of noise during engine operation is also kept to an extremely small noise that hardly poses a problem in practical use. Moreover, since the bottom part is not covered with a sound insulating cover, it has excellent advantages such as increasing ground clearance and increasing the cooling effect of the oil pan.
