Oil pan for vehicle engine {Oilpan For Engine Of Vehicle}

The present invention relates to an oil pan for a vehicle engine, and more particularly to an oil pan having a vibration suppression structure for a vehicle engine.

The oil fan for the vehicle engine is fixed to the lower part of the cylinder block of the engine with several bolts. A plug is installed around the bottom of the oil pan to remove the engine oil, and a gasket intervenes between the oil pan and the cylinder block to prevent leakage.

The oil pan is recessed to hold oil and is produced by pressing or drawing steel sheet. The oil pan may be impacted by protrusions when driving on severely curved roads, and is exposed to harsh environments that must absorb engine heat and vibration. Therefore, oil leaks in oil pans are also common.

Increasingly high-quality cars have made continuous efforts to reduce engine noise, and the effort has been the subject of improvement not only for the engine itself but also for its surrounding components. In particular, the oil pan is a thin part and is closely connected to the engine, and is highly influenced by noise and vibration, and serves to transmit it to the outside. Therefore, improvement of the impact resistance, noise, and damping ability of an oil pan is calculated | required.

With respect to the above problems, the present invention has a main object of providing an oil fan for a vehicle engine that can be minimized to the outside by absorbing noise and vibration transmitted from an engine and can improve impact resistance.

The above object, the oil receiving portion having a recessed form consisting of the side plate and the bottom plate; A flange which is in surface contact with the bottom of the cylinder block and is provided with a plurality of bolt holes extending along an edge of the oil receiving portion; An oil pan for a vehicle engine, the plug being configured to discharge engine oil in the bottom plate or the bottom plate;

 The first and second stainless steel plates are joined in two layers by joining the polymer films therebetween;

10 ~ 30mm width, 5 ~ 15mm height, 80 ~ 200mm bottom ribs of different lengths of two or more different lengths of the vehicle engine oil fan, characterized in that formed by protruding upward from the bottom plate of the oil receiving portion Is achieved by.

According to another feature of the present invention, the bottom rib is three and each end is in contact with the side plate located on the opposite side of the plug while the other end is extended toward the plug to form a non-parallel state.

According to still another feature of the present invention, sidewall ribs having a width of 10 to 30 mm and a height of 5 to 15 mm are provided to protrude toward the oil receiving space at the boundary between the side plate and the bottom plate. Here, the side wall rib is installed between the end point where the bottom rib extends and the side plate on which the plug is located.

According to the above configuration, since the material of the oil pan is made of two layers of stainless steel plate and a polymer film is embedded therebetween, the vibration and noise of the inside are transmitted to the outside with a minimum. This is because the polymer plays a role in absorbing vibration and noise. In addition, the case where the oil pan is ruptured or broken by the impact from the outside is minimized. The unique layout of the ribs also leads to a smooth flow of engine oil inside the oil pan, further increasing the rigidity of the oil pan itself.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a perspective view of an oil pan for a vehicle engine according to an embodiment of the present invention, and FIG. 2 is a plan view. 3 is a cross-sectional view taken along line A-A of FIG. 2, and FIG. 4 is a cross-sectional view taken along line B-B of FIG. 5 is a perspective view of an oil pan according to another embodiment of the present invention, and FIG. 6 is a plan view thereof.

First, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The oil fan for a vehicle engine according to an embodiment of the present invention is composed of an oil accommodating part 1, a flange 3, and a plug 5.

The oil accommodating part 1 for providing an oil accommodating space is composed of a side plate 7 and a bottom plate 9 to have a recessed shape. The bottom plate 9 is usually inclined towards the plug 5 in order to allow the engine oil to settle towards the plug 5. The flange 3 may be in surface contact with the bottom surface of the cylinder block and is provided with a plurality of bolt holes 11 extending along the edge of the oil receiving portion 1. The flange 3 may be provided with a gasket seat (not shown) on which the gasket is seated. The planar shape of the oil pan (see FIG. 2) is determined by the order of the engine manufacturer, and is far from the core of the present invention. That is, it may have a planar shape of various shapes as shown in FIG. 2 or 6.

A plug 5 for discharging the engine oil is installed and fixed to the lower side plate 7 or the bottom plate 9 of the oil receiving part 1 by screwing.

In the oil pan according to the present invention, the first and second stainless steel plates 7a and 7b are doubled by joining each other with the polymer film 7c therebetween (see enlarged view of FIG. 3). The polymer film 7c is inherent, and the two-ply oil pan material is supplied from an external supplier. The material of such oil pans is therefore well known.

At least two bottom ribs 13 having a width (W) of 10 to 30 mm, a height (H) of 5 to 15 mm, and a length (L) of 80 to 200 mm are different lengths, and two or more are separated from the bottom plate (9) of the oil receiving portion. It is formed to protrude upward. As shown, the three bottom ribs 13 are provided in different lengths. The length L of the bottom rib 13 is arrange | positioned in balance in the space called the bottom plate 9. The end of the bottom rib 13 is smoothly finished so that no edge is formed.

The bottom ribs 13 extend in a non-parallel state toward the plug 5 while the other end is in contact with the side plate 7 positioned on the opposite side of the plug. Each bottom rib 13 extends in the form of a branch or a radial extension of each finger in the palm of the body.

As shown, the bottom ribs 13 'installed in the middle extend the shortest, which is to secure a flat bottom surface at a predetermined width in the middle of the bottom plate 9. The bottom ribs 9 are provided with a plurality of valleys toward the plug 5 by the bottom ribs 13. According to this, the flow of engine oil is guided to the plug 5 along each valley.

The main function of the bottom ribs 13 is to increase the stiffness of the bottom plate 9 and to attenuate vibrations and noises. In particular, because they extend out of equilibrium with each other, the bottom plate is not bent by a force in any particular direction. In addition, the bottom plate (9) has a waveform of a certain shape and difficult to vibrate to transmit the vibration and noise of the engine to the outside very little.

According to still another feature of the present invention, the side wall ribs 15 having a width W 'of 10 to 30 mm and a height H' of 5 to 15 mm are disposed at the boundary between the side plate 7 and the bottom plate 9. The side wall ribs 15 are provided between the end point where the closest bottom rib 13 "extends and the side plate 7 in which the plug is located. 5) When the engine oil is discharged, it prevents turbulence and smoothes the flow of the engine oil, helping to be discharged quickly.

The side wall ribs 15 function to smooth the flow of the engine oil and increase the rigidity between the side plate 7 and the bottom plate 9. The side wall ribs 15 are preferably located at points adjacent to the plug 5.

Long side grooves are provided on the outer wall of the bottom plate 9 of the oil pan and the outer wall of the side plate 7 by the side wall ribs 15 and the bottom ribs 13 so that the oil pans can be easily installed in the cylinder block. It will act as a handle (or non-slip means). That is, by mounting each finger of the operator in the grooves by the side wall ribs 15 and the bottom ribs 13, it is possible to stably support the oil pan with one hand.

Specifications specifically illustrated above are merely examples and those skilled in the art will be able to make changes that do not deviate significantly from the illustrated ranges, but such changes are within the scope of the present invention.
