CONSTITUTION: The coupling case such as an oil fan(300) comprises a fluid storage container coupled with plural other components including a skirt(330) of a cylinder block and an oil pump housing, and grooves(310) are formed along a coupling line(350) on T-shaped joint portions(360) contacting the coupling line between the skirt and the oil pump housing so as to allow liquid phase gaskets to be applied thereon.

Description

Coupling case of fluid storage container {A CONSTITUENT CASE OF A LIQUID RESERVOIR}

The present invention relates to a coupling case of a fluid storage container, and more particularly, to a coupling case of a fluid storage container in which a groove is formed so that no leakage of fluid occurs at a portion engaging with a plurality of components.

As is well known, a plurality of fluids, such as oil, are used for lubrication and operation of hydraulic actuating elements, and a plurality of cases (hereinafter referred to as 'coupled cases') for storing the fluid are formed.

For example, an oil pan is coupled to the cylinder block at the bottom of the engine to store engine oil that is circulated for lubrication and cooling of the engine.

When such a coupling case is combined with other components for storing fluid, it is usually fixed by bolts and is usually joined through a gasket made of paper, rubber, or other material.

Grooves are usually formed on the mating surface of the bonding case with other components to apply a liquid gasket to increase the sealing effect.

1 is a view illustrating an oil pan at a lower portion of an engine as an example of a coupling case in which the groove is formed.

As shown in FIG. 1, when the oil pan 100 is coupled to the engine, a skirt 130 of the cylinder block 135 of the engine and an oil pump housing 140 attached to the side of the cylinder block are provided. Coupling with a plurality of structures, a bolt hole for the coupling is formed in a predetermined position of the coupling surface (120).

The groove 110 is formed to be bent at the central portion of the coupling surface 120 of the oil pan 100 to contain the liquid gasket for the sealing effect by the coupling, the shape of the groove 110 is It is as shown in FIG. 2 which is AA sectional drawing of 1.

However, the oil pump housing 140 and the skirt 130 of the cylinder block are joined as separate components, and the joining surface forms a predetermined joining line with respect to the joining surface 120 of the oil pan 100. A coupling portion 160 (hereinafter referred to as a 'T-joint') is formed between the coupling line and the coupling surface of the oil pan.

By the way, the T-joint 170 part by the coupling of the oil pump housing 140 and the skirt 130 of the cylinder block may be formed in the stepped portion of the joint member, in many cases the T-joint 170 part Oil leakage is occurring.

Accordingly, the present invention has been made to solve such a problem, and an object of the present invention is to provide a coupling case of a fluid storage container in which a groove is formed so that no leakage of fluid occurs at the T-joint site.

1 is a view illustrating an oil pan of a lower part of an engine as an example of a coupling case according to the related art in which grooves are formed.

2 is a cross-sectional view taken along the line A-A of FIG.

3 is a block diagram of a coupling case of a fluid storage container according to an embodiment of the present invention.

4 is a cross-sectional view taken along line B-B in FIG. 3.

In order to achieve the above object, the coupling case of the fluid storage container according to the present invention,

In the coupling case formed with a groove (groove) to be coupled to a plurality of other components to form a storage container for storing the fluid, the coupling portion for coupling with the plurality of other components to apply a liquid gasket,

A groove is formed in the T-joint portion coupled to the plurality of other components along a connection line between the plurality of other components.

For example, the coupling case may be an oil pan for storing oil at the lower part of the engine, and the T-joint may be formed by a coupling line between the cylinder block and the oil pump housing.

As another example, the coupling case may be an oil pump housing coupled over a cylinder block and a skirt coupled to the cylinder block, and the T-joint may be formed by a coupling line between the cylinder block and the skirt. .

Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram of a coupling case of a fluid storage container according to an embodiment of the present invention.

The coupling case according to the embodiment of the present invention shown in FIG. 3 illustrates an oil pan for storing oil at the bottom of the engine.

As shown in FIG. 3, the oil pan 300 is coupled to the skirt 330 of the cylinder block and the oil pump housing 340, and on the coupling surface 320, the skirt 330 and the oil pump housing. A groove 310 is formed along the bond line 350 at a portion of the T-joint 360 that is in contact with the bond line 350 with the 340.

4 is a cross-sectional view taken along line B-B of FIG. 3 to show the shape of the groove 310 formed along the joining line.

As shown in FIG. 4, a groove 310 is formed on the coupling surface 320 of the T-joint 360 at a predetermined length along the coupling line 350.

3 and 4 illustrate an oil pan coupled to a combination of the skirt 330 of the cylinder block and the oil pump housing 340, wherein the oil pan has an oil pan having grooves formed along the joining line at the T-joint portion. However, as another example, the coupling case is a cylinder block 335 and the oil pump housing 340 coupled over the skirt 330 coupled to the cylinder block 335, the plurality of other components The cylinder block 335 and the skirt 330 can be used.

Although the preferred embodiment of the coupling case of the fluid storage container of the present invention has been described above, the present invention is not limited to the above embodiment, and those skilled in the art to which the present invention pertains from the embodiment of the present invention. It includes all changes in the range which are easily changed by and deemed to be equal.

According to the embodiment of the present invention, when the fluid is circulated in the assembly of the plurality of components, the fluid can be effectively prevented from leaking at the joining points of the three or more components constituting the assembly.
