ラツプとを含むエアクリーナ装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air cleaner device, and more particularly to an air cleaner device including a connecting tube that connects an air cleaner and a carburetor, and a frame trap that removes dust from intake air.
この種の装置において、連結チユーブは一般的

また連結チユーブにおけるエアクリーナチヤンバ
ーとの結合部分においても、剛性がないと同様の
現象が起こることがある。 In this type of device, the connecting tube is generally made of rubber material, so when negative pressure pulsations are applied to the connecting tube, the connecting tube bends and reduces the cross-sectional opening area of the intake passage. There is a risk that the amount will decrease and the output (horsepower) will decrease.
A similar phenomenon may also occur if there is no rigidity at the connection portion of the connecting tube with the air cleaner chamber.

はなかつた。 On the other hand, in an air cleaner device, a frame trap is provided. The flame trap is located inside the air cleaner chamber, but the air cleaner chamber is often a one-piece blow-molded product, and in the case of a blow-molded product, it is larger than the diameter of the opening. It is difficult to store the items, and it is also difficult to secure the stored items.
Therefore, in the past, it was not always easy to install a frame trap inside the air cleaner chamber.
そこで、本発明は連結チユーブの剛性を低コス

とを目的とする。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an air cleaner device in which the rigidity of a connecting tube is increased at low cost, a sufficient amount of intake air can be supplied to a carburetor, and a frame trap can be easily attached. .

いる。 In order to achieve this object, in the air cleaner device according to the present invention, a locking portion is formed on the inner peripheral surface of the connecting tube on the air cleaner side that connects the air cleaner and the carburetor, and a frame trap is disposed within the connecting tube. The outer periphery of the locking member is fixed by being locked by the locking portion.

A vehicle body frame is constituted by one main tube 2 connected to this head pipe 1, left and right down tubes 3, and left and right back stays 4 connected to these tubes 2 and 3.
A fuel tank 5 is installed astride the fuel tank 5.
An in-line four-cylinder engine 6 is disposed below, and four carburetors 7 are arranged linearly in the left-right direction of the vehicle body. An air cleaner 9 is disposed at the rear end of the fuel tank 5 and below the seat 8 located behind it. Air cleaner 9
The filter element 11 separates the interior of the case body 10 into a dirty side and a clean side, a duct 12 that opens at the front of the vehicle body and communicates with the dirty side inside the case body 10, and a filter element 11 that separates the inside of the case body 10 into a dirty side and a clean side. The air cleaner chamber 14 is connected to the clean side and is fastened and fixed to the case body 10 by a band 13, and is fitted into the opening edge of the air cleaner chamber 14 as shown in FIGS. 4A to D. It is connected to the carburetor 7 by two connecting tubes 15, 15.

る。 In FIGS. 4A to 4D, the connecting tube 15 has at least a bifurcated shape on the carburetor connecting side and is integrally molded, for example, from a rubber-like material. Two protrusions 15a, 15b are provided at a predetermined interval on the outer periphery of the connecting tube 15 near the bifurcated part, and these two protrusions 15a, 15b
The opening edge of the air cleaner chamber 14 is closely fitted between the opening edges of the air cleaner chamber 14. After the two branched ends are fitted into the carburetor 7, they are tightened and fixed by a band or the like at the tightening portions 15c and 15d. A groove 1 serving as a locking portion is provided on the inner wall of the connecting tube 15 between the bifurcated portion and the cleaner side opening end over the entire circumference.
5e is formed in this groove 15e, as shown in FIGS.
A frame trap 16 as shown in FIG. 1 is fitted at its outer edge 16a as a reinforcing member to increase the rigidity of the rubber connecting tube 15. In the case of the bifurcated connecting tube 15, the rigidity of the bifurcated portion is particularly low. Therefore, by arranging a reinforcing member (frame trap 16) in the vicinity of the bifurcated portion, the fitting with the air cleaner chamber 14 can be made easier. Not only can this be done reliably, but also a sufficient amount of intake air can be supplied to the carburetor 7 without the connecting tube 15 being bent even if negative pressure pulsations are applied to the connecting tube 15.

きることになる。 In FIGS. 5A to 5D, the frame trap 16
consists of an outer edge 16a and a mesh-shaped trap 16b fixed to the outer edge 16a. Conventionally, the frame trap 16 was disposed within the air cleaner chamber 14, but in the present invention, the frame trap 16 is disposed within the connecting tube 15, and the outer edge 16 greatly disturbs the air flow.
By fitting the groove 6a into the groove 15e, air can flow smoothly in the intake passage from the air cleaner 9 to the carburetor 7. Also,
A blow-molded product is often used for the air cleaner chamber 14, and since the blow-molded product is one piece, it is not possible to store objects larger than the diameter of the opening, and it is also difficult to fix, so conventionally, a frame trap was installed inside the blow chamber. Although it was very difficult to set the frame trap 16 in the connecting tube 15, the frame trap 16 can be set in the air cleaner chamber 14 together with the end of the connecting tube 15.
また、上述の如く、フレームトラツプを、連結

数の削減が達成されている。 Furthermore, as described above, since the frame trap is utilized as a reinforcing member to increase the rigidity of the connecting tube 15, there is no need to provide a dedicated reinforcing member to increase the rigidity of the tube, and the number of parts can be reduced. As a result, costs and assembly man-hours can be reduced.
なお、上記実施例においては、二股形状の連結
チユーブを用いた場合について説明したが、これ
に限定されるものではない。 Note that in the above embodiment, a case has been described in which a bifurcated connecting tube is used, but the present invention is not limited to this.

止部により係止せしめて固定している。 As described in detail above, in the air cleaner device according to the present invention, a locking portion is formed on the inner circumferential surface of the connecting tube on the air cleaner side, and a frame trap is disposed inside the connecting tube so that the outer peripheral edge thereof is connected to the locking portion. It is locked and fixed by the stop part.

いるのである。 Because of this configuration, the frame trap is utilized as a reinforcing member to increase the rigidity of the connecting tube, and therefore there is no need to provide a dedicated reinforcing member to increase the rigidity, reducing the number of parts and reducing costs. This results in a reduction in the number of assembly steps and the number of assembly steps.

る。 In addition, the frame trap, which was conventionally placed as a single unit inside the air cleaner chamber, is placed inside the connecting tube in this way, and the outer periphery, which greatly disturbs the air flow, is fitted into the inside wall of the tube. This makes it possible to prevent disturbances in the intake air flow in the intake passage from the air cleaner to the carburetor. In addition, since an integral blow-molded product is often used as an air cleaner chamber as a whole, it is not always easy to store items larger than the diameter of the opening, and it is also difficult to secure the stored items. It was very difficult to install a frame trap inside the air cleaner chamber, but by installing the frame trap inside the connecting tube as described above,
This can be easily installed in the air cleaner chamber together with the end of the connecting tube.
