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 intake air of an engine.

[0002]

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

As shown in FIGS. 5 and 6, the radial seal type has an air inlet 2 and an air outlet 3 and is a cylindrical element 20a to be loaded into an air cleaner body 1 which is sealed by a cover (not shown). A seal member 21a is provided on one end face located on the air outlet side to abut against the outer peripheral face of the seal tube 5 formed on the air outlet 3, and the other end face located on the cover side is pressed by the cover, whereby the seal is formed. 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 sealing structure of the element is different between the pressure seal type and the radial seal type, the air cleaner bodies for loading the elements are dedicated to each other and are not interchangeable. In particular, in recent years, air cleaners for large and medium sized commercial vehicles have been shifting to radial seal type due to weight reduction and the like. However, since the seal structure is significantly different, the element must also correspond to a 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 a radial seal type air cleaner body.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problem, and has a structure in which an air cleaner body having an air inlet and an air outlet is sealed in a cover. A cylindrical element, provided with a sealing member abutting on 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 mounted on the other end face located on the cover side .
Front with radial seal air cleaner body on end plate
Pressing with the protrusion provided at the center of the cover
The seal member is attached to the side wall of the air cleaner body and the seal.
Press the center cap, which is pressure bonded to the outer surface of the tube.
In a sealed air cleaner body, the sealing member
The tightening bolt that contacts the side wall of the air cleaner body
And a central hole into which the cover is detachably fitted .

[0006]

According to the above construction, when the radial seal type air cleaner body is loaded, the element is inserted in a state where the center cap is fitted in the center hole of the end face plate at the other end face located on the cover side, and the center cap is fixed by the cover. Press and seal with the seal member. When loading into a pressure seal type air cleaner body, remove the center cap, pass the center bolt through the center hole of the end face plate, tighten with a nut, seal with a seal member, and use either the radial seal type or the pressure seal type. This enables compatibility with the air cleaner body.

[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 closed by a cover 6. 7 is a tubular 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 at one end face located on the side of the air outlet 3 and in contact with the side wall 4 of the air cleaner body 1 and the outer peripheral face of the seal tube 5. The center cap 11 is detachably fitted in the center hole of the end face plate 10 at the other end face located on the cover 6 side.

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

When loading the air cleaner body of the pressure seal type, the center cap 11 is removed,
As shown in FIG. 3, a center bolt 23 is passed through a center hole of the end face plate 10, and is tightened with a nut 24, and is sealed by a seal member 8 which comes into contact with the side wall 4 of the air cleaner body 1.

Accordingly, when the element 7 according to the present invention is mounted on a radial seal type air cleaner body, the center cap 11 is fitted in the center hole of the end face plate 10 and the pressure seal type air cleaner body is also mounted. end Remove the center cap 11 in the case of loading
Insert the center bolt 23 through the center hole of the face plate
By fixing the air cleaner body with the air cleaner body 24, the air cleaner body is compatible with any type of air cleaner body.

[0012]

According to the present invention as described above, according to the present invention, Jer
Air cleaner element that can be installed in both radial seal type and pressure seal type air cleaner bodies with different seal types.
Has the advantage that it can provide
