Description

Oil suction pipe structure of car

FIELD OF THE INVENTION

The present invention relates to an oil suction pipe structure of a motor vehicle, and more particularly, to a pipe structure in which oil stored in an oil pan mounted under a cylinder block is sucked.

The engine of an automobile causes many parts to rub against each other during rotation, and among these parts, they are often rubbed at high speed under a considerable load. The force used in this friction-producing part is a force that causes a loss in relation to the force obtained in the expansion stroke of the cylinder, and the friction between parts naturally wears out the parts and shortens the life, and overall the overall performance of the engine It causes the deterioration.

Therefore, the engine is equipped with a lubrication device, and its configuration is an oil pan, which is a container for storing engine oil, an oil pump that pumps oil stored in the oil pan to each moving part of the engine, and suction in which oil stored in the oil pan is sucked and moved. And a hydraulic regulator, which is a valve device for adjusting the pressure of the oil pumped from the oil pump to a constant pressure.

Among them, as shown in FIG. 1, the oil pan 1 is a container in which a steel plate or an aluminum plate is pressed, and is bolted to the lower portion of the cylinder block 2 with a gasket. In addition, the oil pan 1 also serves to lower the temperature of the oil by dissipating heat to the outside.

[Prior art]

A conventional oil pan structure which serves as described above is shown in cross section in FIG. As shown, the oil pan 1 in which the oil is stored has an upper portion, and a lower surface thereof is inclined downward from one side, and a portion of the oil pan 1 is deeply recessed to form a recess. That is, oil is stored in the recess. A suction pipe 4, which is a moving passage of oil which is extended upward from the position close to the lower surface of the concave portion and pumped by the oil pump 3, is provided. A mesh body 5 is attached to the lower end of the suction pipe 4 to remove impurities in the oil. The lower end of the suction pipe 4 is located about 5 to 10 mm above the lowest surface of the oil pan 1 in preparation for damage to the oil pan 1 due to an impact during driving.

In addition, a baffle plate (6: baffle plate) for preventing oil from flowing from side to side or up and down by the vibration of the vehicle is provided at the upper portion of the recess. That is, the baffle plate 6 completely closes the upper portion of the concave portion, thereby preventing oil from being introduced to one side by vibration of the vehicle and introducing air into the suction pipe 4.

However, the conventional baffle plate 6 can suppress the up and down flow of oil because the structure only seals the upper portion of the concave portion. However, the structure of the baffle plate 6 is almost impossible to suppress the left and right flow. When it is pulled to one side, the open lower end of the suction pipe 4, which should always be immersed in the oil, is exposed to the outside, and air is likely to penetrate into the suction pipe 4, and the air penetrated into the oil is effective. There is a problem that it interferes with lubrication, and thus seriously damages each part of the engine.

The present invention devised to solve the above problems, an object of the present invention is to improve the structure of the intake pipe to provide an oil intake pipe structure of a vehicle that can easily discharge the air penetrated to the intake pipe by the oil biased to one side. have.

In order to achieve the above object, the present invention, the lower end is located in close proximity to the bottom surface of the oil pan is mounted to the cylinder block is stored oil, the upper end is connected to the oil pump oil suction of the automobile is moved by forced suction In the pipe structure, a cap for storing a predetermined amount of oil is covered to the bottom of the suction pipe is always filled with oil.

The cap is covered with a predetermined distance from the outer circumferential surface of the suction pipe, the lower portion is in close contact with the outer peripheral surface of the suction pipe so as not to leak, the upper portion is in close contact with the outer circumferential surface of the suction pipe and the communication groove is moved in several places Characterized in that formed.

It is preferable that the communication groove is formed in three places.

According to the configuration of the present invention described above, since the oil is always filled in the cap, the lower end of the suction pipe is also immersed in the oil irrespective of the oil level of the oil, thereby preventing external air from penetrating into the suction pipe. .

EXAMPLE

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

3 is a cross-sectional view showing the structure of the oil intake pipe according to the present invention, and FIG. 4 is a cross-sectional view taken along line A-A of FIG. 3 showing that the cap, which is the main part of the present invention, is covered with the intake pipe.

In describing the configuration of the present embodiment, the same parts as in the prior art are omitted in order to avoid duplication of explanation.

As shown in FIG. 3, an inlet pipe 4 is installed in the lower portion of the cylinder block 2 so that oil is forced into the oil pan 1 by driving the oil pump 3. do. The suction pipe 4 has an upper end connected to the oil pump 3, and a lower end thereof is located close to the bottom of the oil pan 1. The lower end of the suction pipe 4 is attached to the mesh body 5 for removing impurities in the oil.

In addition, a baffle plate 6 is installed in the transverse direction in order to prevent a sudden change of oil level in the oil pan 1 to prevent air from penetrating into the suction pipe 4.

Here, in the present invention, in order to ensure that the lower end of the suction pipe 4 is always immersed in the oil, even if the oil is biased to one side by driving of the vehicle, a cap 10 in which a certain amount of oil is always stored is covered.

The cap 10 is covered to be disposed at a predetermined distance from the outer circumferential surface of the suction pipe 4, the lower part is in close contact with the mesh body 5 so that oil does not leak, while the upper part is shown in FIG. Similarly, although in close contact with the outer circumferential surface of the suction pipe 4, the communication groove 11 in which the oil is moved is formed in several places, in this embodiment, three places.

That is, the oil is introduced into the cap 10 through the communication groove 11, and a certain amount is always stored, and even if the oil level of the oil is biased to one side as shown in FIG. 3 due to the vibration during driving of the vehicle. As described above, since the oil in the cap 10 does not leak through the sealed lower portion, the lower end of the suction pipe 4 may always be immersed in oil. Therefore, the situation where air penetrates through the suction pipe 4 can be prevented.

As described above, the present invention covers the lower end of the suction pipe 4 with a cap 10 capable of storing a certain amount of oil at all times, so that even if the oil is biased to one side due to the vibration of the driving, the lower end of the suction pipe 4 is always It can be kept immersed in oil. Therefore, the situation where air penetrates into the suction pipe 4 can be prevented, and smooth lubrication action can be maintained.

In addition, this invention is not limited to said Example, It can variously change and implement in the range which does not deviate from the summary.
