Description

[Detailed Description of the Invention] The present invention relates to an air cleaner device for a motorcycle, and more particularly to a mounting and housing structure for an element disposed in an air cleaner case of an air cleaner device.

For example, in the element mounting and housing structure of an air cleaner device for motorcycles,
As described in Publication No. 11659, positioning is performed by fitting the inner circumferential surface of a cylindrical element into an outlet port formed protruding inside the air cleaner case. By covering the element with a lid, both end surfaces of the element are held between the lid and the air cleaner case, thereby positioning and fixing the element to the air cleaner case.

On the other hand, in some air cleaner devices for motorcycles, the axis of the element is arranged to face the traveling direction of the vehicle. In such an air cleaner device, the flow path of filtered air to the vaporizer can be configured as straight as possible, and the efficiency of air flowing into the vaporizer can be improved.

By the way, in the element mounting and housing structure of the conventional air cleaner device described above, the element is positioned in the outlet port that is protruded inside the air cleaner case, so the element cannot slide along its axis. If you do not do this, you will not be able to attach or detach it to the air cleaner case. Therefore, in order to improve the air inflow efficiency of this conventional air cleaner device, when the axis of the element is arranged along the traveling direction of the vehicle as described above, the air cleaner case of the vehicle is Space for attaching and detaching the element must be secured at the front or rear, making it impossible to effectively utilize the space in the vehicle.

The present invention was developed in view of the above-mentioned conventional problems, and is intended to improve the effective use of vehicle space in an air cleaner device for motorcycles in which the axis of the cylindrical element is oriented in the direction of vehicle travel. The purpose of the present invention is to provide an air cleaner device for a motorcycle equipped with an element mounting and accommodating structure that allows for the installation and storage of elements. The housing hole is removably provided with a lid that closes the housing hole, and the air cleaner case and the lid are each provided with a presser portion that comes into contact with a circumferential surface of the element, and the element is held in the presser portions. Thus, it is clamped and positioned and fixed inside the air cleaner case.

Hereinafter, one embodiment of the air cleaner device for a motorcycle according to the present invention will be described in detail.

1, 2, and 3 are partially cutaway top views showing an air cleaner device according to the present invention, respectively;
FIG. 2 is an AA sectional view and a partially cutaway side view thereof.

The air cleaner case 20 of this air cleaner device 1 consists of a lower case 21 that covers the bottom of the air cleaner case, and an upper case 23 that fits into a recess 22 formed at the upper peripheral end of the lower case. , this Atsupah case 2
A receiving hole 24 for the element 30 is formed in the upper part of the air cleaner case 20 and opens upwardly of the air cleaner case 20 (FIG. 2). This accommodation hole 24 is
A protrusion 25 is provided at the peripheral edge of the opening, into which a lid 40 is fitted. The lid body 40 is further attached and fixed to the upper case 23 at both side portions 41, 41 by attachment screws 50, and closes the accommodation hole 24 (FIGS. 1 and 3). The above-mentioned upper case 23 and lower case 21 are integrally connected by a fastening means such as a mounting screw (not shown) (FIG. 3).

On the other hand, the bottom surface 26 of the lower case 21
At the front and rear ends (Fig. 2), a pair of presser steps 27,
28 (pressing portion) is formed to protrude, and further, pressing pieces 43 and 44 (pressing portions) are formed to protrude from the front and rear ends of the ceiling surface 42 of the lid body 40 (FIG. 2). Note that these presser step portions 27 and 28 and presser pieces 43 and 44 are respectively formed at positions facing each other when the accommodation hole 24 is closed with the lid body 40. In addition, the surface of these pressing parts is
As shown in FIG. 3, when an element 30 having a cylindrical shape is arranged with its axis facing the direction of travel of the vehicle, the circumferential surfaces 3 of both ends of the element 30
1 and 32 are formed in an arcuate shape to press and hold them.

A pair of air cleaner duct tubes 60 for sucking air are fitted and supported at the rear of the lower case 21 in the air cleaner case 20 (FIGS. 1 and 3), and at the front of the lower case 21. An outlet port 29 is integrally formed with the lower case (the first
Fig. 2). This outlet port 29 is
The rear surface 8 of the chamber 80 is connected to the rear surface 8 of the chamber 80 via the connecting tube 70 fitted into the outlet port.
1, and the front surface 8 of this chamber 80
Four air cleaner connecting tubes 90 each connected to an inlet port of a carburetor (not shown) are fitted into and supported by 2.

Therefore, as shown in FIG. 1, the air sucked into the air cleaner case 20 from the air cleaner duct tube 60 in the direction of arrow B is filtered by the element 30 and then flows through the outlet port 29. After the air is fed into the chamber 80 as shown by the arrow C and the disturbance in the intake flow velocity of the air is corrected within the chamber, the air is further fed into the air cleaner connecting tube 9 as shown by the arrow d.
0 to the carburetor inlet port. In addition, the reference numeral 100 in FIGS. 1 and 2
1 is a connecting tube band, 110 is a breather pipe, and 120 is a drain pipe.

According to such an air cleaner device 1, in order to take out the element 30 from the air cleaner case 20, use the mounting screws 50 shown in FIGS. 1 and 3.
, and move the lid body 40 upward as shown by the dashed line in FIG. 2 to open the accommodation hole 24.
Thereafter, the element 30 may be removed from the air cleaner case 20 by moving it upward (above with respect to the vehicle) as shown by arrow E. Further, in order to accommodate the element 30, the circumferential surface of the element 30 may be placed on the holding steps 27 and 28, and then the above-mentioned operation may be performed in reverse. At this time, the element 30 can be positioned and fixed with respect to the air cleaner case 20 by covering the air cleaner case 20 with the lid 40, so that the holding steps 27, 28 and the holding pieces 43, 44 press and hold the circumferential surface of the element 30. It will be done automatically by doing.

In the above embodiment, the air cleaner case 20 is divided into two parts, the lower case 21 and the upper case 23, which are formed separately. However, the present invention is of course not limited to the above embodiment. , the lower case 21 and the upper case 23 may be formed integrally.

As described above, the present invention is configured such that the air cleaner element of the air cleaner device, whose axis is oriented toward the direction of travel of the vehicle, can be attached and detached from above the vehicle. There is no need to provide a space for installing and removing the cleaner element, and the space in the vehicle can be used effectively. Furthermore, since the element of the air cleaner device is held at its circumferential surface by the holding portion provided on the lid body and the air cleaner case, and is positioned and fixed within the air cleaner case, the element can be easily configured. The element can be held securely, and maintenance and inspection work can be facilitated.
