Description

Bellows pipe structure of oil strainer

The present invention relates to the structure of the corrugated pipe of the oil strainer, in particular to suppress excessive deformation of the corrugated pipe to block the rapid movement of the enclosure to prevent the enclosure from colliding with other parts, even if the external impact is filled inside The present invention relates to a corrugated pipe structure of an oil strainer capable of expecting an effect of increasing durability by absorbing and buffering a shock.

5 shows a conventional oil strainer,

The front end of the corrugated pipe (2) is connected to the oil pump (1), the lower end of the corrugated pipe (2) is provided with a housing (4) having a filter net (3) is installed, the lower portion of the housing (4) roller (5) The rail 6 is formed on the top of the bottom plate of the oil pan 7 in which the corrugated pipe 2 is installed.

In the conventional oil strainer configured as described above, when an inclination occurs in the oil pan 7 due to the vehicle traveling on a non-sloped road, the housing 4 coupled to the lower end of the corrugated pipe 2 is formed by the roller 5. The oil is pumped through the housing 4 while being moved along the rail 6 formed on the bottom surface and directed to one side of the oil pan.

However, the corrugated pipe applied to the conventional oil strainer has a problem in that the corrugated pipe is shaken by the vibration and frequently collides with the oil pan, and at the same time, a strong noise is generated when the corrugated pipe and the oil pan collide with each other. Therefore, the problem that the oil pressure to be pumped drops as the pipe friction increases when the oil is inhaled.

Therefore, the present invention for solving the above problems to form a spiral outer wall of the corrugated pipe by staggering the spirally bent shape of the shape, to form an inner wall to have a predetermined distance with the outer wall, and acts as a damper between the outer wall and the inner wall By filling the fluid to prevent the excessive deformation of the corrugated pipe to block the rapid movement of the enclosure to prevent the enclosure from colliding with other parts, even if the external impact is applied to the fluid filled inside to absorb the shock The purpose of the present invention is to provide a corrugated pipe structure of an oil strainer that can be expected to have an effect of increasing durability by cushioning.

The present invention for achieving the above object,

An outer wall which is coupled to staggered staggered with each other in a 'ㄹ' shape and is formed to be contracted and tensioned by movement of the steel;

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 4.

In the description of the present invention, the same components as in the prior art will be denoted by the same reference numerals to avoid redundant description.

The corrugated pipe of the present invention has a roller (5) formed on the lower side to connect the housing (4) capable of rolling movement to the oil pump (1) in response to the inclination of the oil pan (7) is an oil pan ( 7) It is to allow the oil to be pumped through the enclosure (4) to move to one side while moving inside.

The corrugated pipe is composed of an outer wall 10 and an inner wall 12, the outer wall 10 is coupled to each other to cross a plurality of steel 11 formed in the cross-section 'L' shape as shown in FIG. The outer wall 10 is configured to be contracted and tensioned by the movement of the steel (11).

The inner wall 12 is formed as a soft material that can bend in response to the movement of the outer wall 10.

A fluid 13 having a viscosity is filled between the inner wall 12 and the outer wall 10 to allow the fluid 13 to absorb an impact applied from the outside.

On the other hand, between the outer wall 10 and the inner wall 12, a plurality of diaphragm 14 capable of shrinkage in a plurality of places is formed.

The diaphragm 14 is formed in four places to cross the outer wall 10 and the inner wall 12, as shown in FIG. 2, and several orifices 15 are formed in the middle of each diaphragm 14, and this orifice is formed. The flow of fluid 13 is restricted through 15.

Referring to the operation of the present invention configured as described above is as follows.

When the oil pan 7 is tilted as the vehicle travels the slope, the housing 4 moves in the direction in which the oil pan 7 is inclined, and the outer wall 10 of the wrinkle tube is moved by the movement of the housing 4. ) And a pressure change occurs between the inner wall 12.

That is, when the housing 4 is moved to the right side in the drawing as shown in FIG. 4, pressure is applied to the outer wall 10 of the corrugated pipe in the A direction, and the steel 11 in the A direction contracts and becomes dense, and vice versa. Steel 11 in the direction is tensioned so that the corrugated pipe is bent along the direction of movement of the enclosure (4).

In addition, at this time, as the pressure is applied to the corrugated pipe in the A direction, the fluid 13 of the high pressure portion moves to the low pressure portion through the orifice 15 to allow the outer wall 10 to be bent, and the orifice ( Since the 15) acts as a resistance to the movement of the fluid 13, it is possible to prevent the bending of the corrugated pipe and the oil pan by preventing the sudden bending of the corrugated pipe.

In addition, the fluid 13 serves as a damper for buffering an external shock applied to the corrugated pipe.

That is, when the external shock is applied to the corrugated pipe, the vibration caused by the shock is absorbed by the fluid 13 filled in the outer wall 10 and the inner wall 12, and thus the vibration of the corrugated pipe due to the vibration can be significantly reduced. Will be.

In addition, since there is no bending in the inner wall 12 of the corrugated pipe applied in the present invention, friction does not act on the oil to be pumped, thereby reducing hydraulic loss during oil pumping, thereby smoothly supplying oil to each friction part of the engine. .

As described above, the present invention forms the outer wall of the corrugated pipe by staggering the spirally bent steels alternately, and forms an inner wall to have a predetermined distance from the outer wall, and serves as a damper between the outer wall and the inner wall. By filling the, it prevents excessive deformation of the corrugated pipe to block the rapid movement of the enclosure to prevent the enclosure from colliding with other parts, and even if an external shock is applied, the fluid filled inside absorbs the shock and cushions the durability. The effect of providing the corrugated pipe structure of the oil strainer can be expected to expect this increased effect.
