The present invention relates to a vehicle air cleaner, and more particularly, is mounted and supported by a bearing inside the air cleaner so that the element can be rotated in the same direction by the suction air rotating around the bone, It relates to a vehicle air cleaner is installed along the iron core up and down.

Generally, automobiles are classified into passenger cars, buses, and trucks according to their type, but even the same type of vehicles, gasoline vehicles using gasoline as fuel, diesel vehicles using diesel fuel, and LPG using LPG as fuel Sometimes classified as a vehicle.

In addition, a vehicle such as a bus or truck mainly used for business purposes according to the purpose of use of the vehicle is called a commercial vehicle in comparison with a passenger vehicle.

Commercial vehicles that mainly use diesel engines are not required to inhale the mixture of fuel and air into the cylinder, but to ignite the fuel by injecting the fuel through a high-pressure injection nozzle while injecting outside air into the cylinder and compressing it at high pressure. Get power.

At this time, since the intake air contains dust or fine foreign matters contained in the atmosphere, it is necessary to supply these dusts or foreign substances in a filtered state when supplying them into the cylinder.                         

For example, in a truck, the air supplied to the engine is sucked into the vehicle through the intake duct assembly, purged in the air cleaner, and then supplied to the engine. It is designed to filter dust or foreign matter through.

6 is a schematic diagram of a conventional air cleaner internal structure, in which a dry air cleaner 10 for a commercial vehicle is shown.

As shown, in the center of the inner space formed by the cylindrical body 11, the upper cover 12 mounted on the top of the body 11, the lower cover 13 mounted on the bottom of the body 11 An element 14 for filtering foreign matter and water is mounted, and an air inlet 15 is formed in the lower part of the body 11 for air suction, and the upper cover 12 is connected to allow air to enter the engine. The outlet 16 is formed to be in communication with the internal space of the element (14).

In addition, in order to lower the suction pressure and increase the engine output, an air guide 17 is installed inside the body 11 to allow centrifugal force to act on the air sucked into the air inlet 15. The air sucked through the air guide 17 rotates around the element 14 and passes through the element.

However, the conventional air cleaner made as described above has the following problems.

First, since the element 14 is fixed even when the centrifugal force acts on the sucked air, as shown in FIG. 7A, even when the air rotates, the element 14 collides with the element 14 to generate airflow resistance and vortex at the end of the element feather. As a result, suction power is not greatly improved.

In addition, even if the air rotates outside the element 14, when passing through the element, the rotational force is greatly reduced inside the element due to the resistance upon passing.

As shown in FIGS. 7A and 7B, the deformation of the element 14 occurs in the rotational direction due to the rotation of the outside air, the element outer surface contraction occurs, and the bone gap becomes narrow as the element collar end contracts. Of course, problems arise in contact with each other.

Therefore, the present invention is invented to solve the above problems, the element is installed so as to be rotatable by the intake air, the iron core is installed at the outer end of the element, eliminating the deformation and crushing of the element, and The same airflow resistance and vortex are eliminated, and the iron core acts as a mass by the centrifugal force generated during rotation, maintaining the outer posture of the element and expanding the bone gap of the element and preventing the double end end contact. It is an object of the present invention to provide an element for a vehicle in which the suction area is increased, thereby reducing the suction pressure and improving the engine power.

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

According to an aspect of the present invention, there is provided a vehicle air cleaner configured to filter internally and sucked air therethrough after rotating the element.

The element is mounted and supported by a bearing inside the air cleaner so that the element can be rotated in the same direction by the intake air rotating around the core, and iron cores are attached to the end of each valley of the element up and down along the valley.

In particular, the element,

Rotating support is integrally coupled to the upper and lower ends, and is mounted in such a manner that each boss portion protruding from the air cleaner upper cover and the lower cover is fitted into the inner circumference of the rotatable support. It is characterized in that the mounting is supported by a bearing installed between.

In addition, it is characterized in that a plurality of blades for receiving the rotational force of the air sucked in the outer circumference of the support.

In addition, the iron core is characterized in that the adhesive is installed on the inner end of each valley of the element.

In addition, the iron core is characterized in that the insertion is fixed between the two layers of non-woven fabric or lingu that constitutes the element at each end of the bone.

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

1 is a longitudinal cross-sectional view showing the internal configuration of a vehicle air cleaner according to the present invention, Figure 2 is a perspective view showing an element with an iron core in the present invention, Figure 3 is an element with an iron core in the present invention Is a cross-sectional view taken along the line 'A-A' in FIG.

4A and 4B are cross-sectional views of elements according to embodiments in which the iron core is attached in the present invention, and FIG. 5 is a view for explaining the effects of the present invention.

In the air cleaner 10a of the present invention, reference numeral 15 denotes an air inlet through which air is sucked, and reference numeral 17 denotes an air guide installed in the air inlet 15 to allow the sucked air to rotate outside the element 14. Reference numeral 16 denotes a discharge port installed in the center of the upper cover 12 and positioned in communication with the internal space of the element 14.

First, in the air cleaner 10a according to the present invention, rotary supports 18a and 18b having a plurality of blades 19 for rotating the elements are integrally installed at the upper and lower ends of the elements 14 embedded therein. .

The element 14 is installed in the center of the inner space of the air cleaner 10a, the upper end and the lower end are fitted to each of the bosses 12a and 13a protruding from the upper cover 12 and the lower cover 13, more specifically, the upper end. Rotating supports 18a and 18b integrally fixed to the lower end and the lower end are fitted into and coupled to the bosses 12a and 13a, and between the inner circumference of the rotatable supports 18a and 18b and the outer periphery of the bosses 12a and 13a. The bearings 21a and 21b are provided.

As a result, when the air sucked into the inlet 15 is rotated circumferentially around the element 14 by the air guide 17, the respective rotary supports 18a and 18b and the element 14 by the sucked air. ) Rotates integrally in the same direction as the rotational direction of the air, wherein the blades 19 of each of the rotary supports 18a and 18b receive the rotational force of the sucked air, so that the rotary supports 18a and 18b and the element ( 14) can be rotated more smoothly.

Here, even without the blade 19, the element 14 is supported and installed by the rotary support (18a, 18b) including the bearing (21a, 21b) can be sufficiently rotated by the rotation of the air, but in order to increase the rotational force It is preferable to install the blade 19.

As such, when the element 14 rotates in the same direction as air, the rotational speed of the element is substantially equal to the rotational speed of the intake air, and the airflow resistance and vortex as in the prior art are eliminated. It passes through the element 14, which in turn lowers the suction pressure so that the engine output can be improved.

On the other hand, in the present invention, the iron core 22 capable of functioning as a mass body is attached to the inner end of each valley 14b in the element 14.

The iron core 22 is installed to be long along each bone in the element 14 up and down direction, wherein the method of attaching the iron core 22 to the iron core 22 as shown in FIG. 4A in each bone portion 14b. The method of directly attaching the nonwoven fabric or sheet 14a constituting (14) using an adhesive or inserting and fixing the iron core 22 between two layers of the nonwoven fabric or sheet 14a as shown in FIG. Available.

Hereinafter, the operation state and the effect of the air cleaner according to the present invention will be described.                     

First, when the air is sucked through the inlet port 15 in the air cleaner 10a of the present invention as described above, the air is rotated outside the element 14 while passing through the air guide 17, this rotating air Rotate the upper and lower rotary support (18a, 18b) through the blade 19, so that the entire element 14 is rotated in the rotational direction of the air.

When the element 14 is rotated in this manner, the rotational speed of the element 14 is substantially equal to the rotational speed of the intake air, eliminating the deformation and distortion of the element, and the generation of airflow resistance and vortex as in the prior art Disappears and the intake air naturally passes through the element.

In addition, the iron core 22 installed at the end of each bone portion 14b of the element 14 acts as a mass by the centrifugal force generated during rotation, maintaining the element outer posture and expansion, and the bone gap of the element is extended and doubled The tip end contact is prevented, and the suction area is increased, thereby reducing the suction pressure and improving the engine power.

As described above, according to the air cleaner for a vehicle according to the present invention, the element is installed to be rotatable by intake air, and the rotational speed of the element is substantially equal to the rotational speed of the intake air. No distortion, no airflow resistance and vortex generation as in the prior art, and the intake air naturally passes through the element.                     

In addition, due to the centrifugal force generated during rotation, the iron core installed at the outer end of the element serves as a mass body, thereby maintaining the element's outer posture and expansion, and extending the bone gap of the element and preventing the double urge end contact, and increasing the suction area. Therefore, the suction inlet pressure is reduced and the engine output is improved.

In addition, in the case of commercial vehicles, unlike the passenger car, the air cleaner is exposed to the outside, and the nonwoven fabric or margin is always exposed to moisture. Thus, the wet and dry phenomenon is repeated, and the nonwoven fabric is easily deformed by the suction resistance of the air. There was a disadvantage that the suction negative pressure is increased, this problem can be solved.

In addition, when the engine rotates at high rpm, the element is more inflated and the rotational speed is increased to increase the amount of air required at high rpm, thereby increasing vehicle acceleration and responsiveness.

In addition, even if water is introduced there is an effect to disperse the water particles to the cover surface by the centrifugal force.
