Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner element for filtering engine intake air.

[0002]

2. Description of the Related Art There are two types of air cleaner elements for filtering intake air of an engine, which are a pressure seal type and a radial seal type in an air cleaner body. As shown in FIGS. 3 and 4, the pressure-seal type has an air inlet 2 and an air outlet 3, and is provided on the air outlet side of a cylindrical element 20 to be loaded into an air cleaner body 1 which is sealed by a cover (not shown). A seal member 21 that comes into contact with the side wall 1a of the air cleaner body 1 is provided on one end face located, and a center bolt 23 is passed through a center hole of an end face plate 22 on the other end face located on the cover side and tightened with a nut 24. This is a structure in which 21 is pressure-bonded to the side wall of the air cleaner body 1.

As shown in FIGS. 5 and 6, the radial seal type has a cylindrical element 20a which has an air inlet 2 and an air outlet 3 and is mounted in an air cleaner body 1 which is sealed by a cover (not shown). A seal member 21a that abuts the outer peripheral surface of the seal tube 5 formed at the air outlet 3 is provided on one end surface located on the air outlet side, and the other end surface located on the cover side is pressed by the cover to seal. This is a structure in which the member 21a is pressure-bonded to the outer peripheral surface of the seal tube 5.

[0004]

As described above, since the pressure seal type and the radial seal type have different sealing structures of the elements, the air cleaner bodies for loading the elements are dedicated to each other and are not compatible with each other. In particular, in recent years, air cleaners for large and medium-sized commercial vehicles are shifting to the radial seal type due to weight reduction, etc., but since the sealing structure is drastically different, the element must also correspond to the pressure seal type air cleaner body. However, in order to adopt the radial seal type, there is a disadvantage that the pressure seal type air cleaner body must be changed to the radial seal type air cleaner body.

[0005]

DISCLOSURE OF THE INVENTION The present invention is provided to solve the above problems, and the structure thereof is to be loaded into an air cleaner body which has an air inlet and an air outlet and is sealed by a cover. A cylindrical element, provided with a seal member that abuts the side wall of the air cleaner body and the outer peripheral surface of the seal tube on one end face located on the air outlet side, and a center member in the center hole of the end face plate on the other end face located on the cover side. The cap is detachably fitted.

[0006]

With the above construction, when the air cleaner body of the radial seal type is to be loaded, the element is inserted with the center cap fitted in the center hole of the end face plate of the other end face located on the cover side, and the center cap is attached by the cover. Press and seal with the sealing member. Also, when mounting on a pressure seal type air cleaner body, remove the center cap, insert the center bolt through the center hole of the end plate and tighten it with a nut, and seal with a seal member, either a radial seal type or a pressure seal type. It is also compatible with air cleaner bodies.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is an air cleaner body,
It has an air inlet 2 and an air outlet 3 and is sealed by a cover 6. Reference numeral 7 is a cylindrical element according to the present invention.

As shown in FIG. 2, the element 7 according to the present invention is provided with a seal member 8 which abuts the side wall 4 of the air cleaner body 1 and the outer peripheral surface of the seal tube 5 on one end surface located on the air outlet 3 side. This is a structure in which a center cap 11 is detachably fitted in a center hole of an end face plate 10 on the other end face located on the cover 6 side.

Since the present invention has the above-described structure, when it is mounted in a radial seal type air cleaner body, as shown in FIG. 1, a center hole is formed in the center hole of the end face plate 10 on the other end face located on the cover 6 side. Insert the element with the cap 11 fitted, and insert the protrusion 1 at the center of the cover 6.
2 presses the center cap 11 to attach the seal member 8 to the side wall 4 of the air cleaner body 1 and the seal tube 5.
Seal by pressure-bonding to the outer peripheral surface of.

When the air cleaner body of the pressure seal type is to be mounted, the center cap 11 is removed,
As shown in FIG. 3, the center bolt 23 is penetrated through the center hole of the end face plate 10 and tightened with the nut 24, and sealing is performed by the seal member 8 that abuts the side wall 4 of the air cleaner body 1.

Therefore, the element 7 according to the present invention is in a state where the center cap 11 is fitted when it is mounted in a radial seal type air cleaner body, and when it is mounted in a pressure seal type air cleaner body. By removing 11, it is compatible with any type of air cleaner body.

[0012]

As described above, according to the present invention, the one end surface located on the air outlet side is provided with the seal member that abuts the side wall of the air cleaner body and the outer peripheral surface of the seal tube, and the other end surface located on the cover side is provided. Due to the structure in which the center cap is removably fitted in the center hole of the end plate, it has the advantage of being compatible with both radial seal type and pressure seal type air cleaner bodies with different seal structures. are doing.
