Description

【０００１】
【発明の属する技術分野】
この発明は自動２輪車のエアクリーナ装置に関する。
【０００２】
【従来の技術】
自動２輪車のエアクリーナは、後輪等の跳ね上げた水や泥が吸入ダクトへ入り込まないように配慮する必要があり、例えば、実公昭５６−３５４２２号には、後輪用のリヤフェンダの前部を十分長く前方へのばし、ここにエアクリーナを設けることによりリヤフェンダの前端部で吸入ダクトの遮蔽を行うようにしている。
【０００３】
【発明が解決しようとする課題】
吸入ダクトに水や泥が侵入しないようにするためには、何らかの遮蔽物を設ける必要があり、上記従来例では、リヤフェンダの前方延出部がこれに相当する。しかしこのようにすると、部品点数や重量が増大するので、このような特別の遮蔽物を不要にする構造が望まれる。特に前半側が省略された形式のリヤフェンダを採用した場合、水や泥がエアクリーナへかかり易くなるので、このような配慮が切望される。本願は係る要請を満たすものである。
【０００４】
【課題を解決するための手段】
上記課題を解決するため本願に係る自動２輪車のエアクリーナ装置に関する第１の発明は、車体フレームを、前後方向に配設されたメインパイプと、メインパイプの後端部から下方へ延びるセンターパイプと、このセンターパイプの上部から後方へ延出するシートレールと、このシートレールとセンターパイプの下部とを斜めに結ぶリヤパイプとで構成し、リヤフェンダを後輪上方へその略後半部分側だけを覆うように設け、後輪及びリヤパイプの前方かつ車体の左右方向一側面にエアクリーナを設けた自動２輪車において、
エアクリーナケースの開口部を覆いかつ吸入ダクトが取付けられたエアクリーナケースカバーと、エアクリーナケースカバーのさらに外側から吸入ダクトを覆う外カバーを設け、エアクリーナケースカバーの一部を前記開口部の縁よりも後方へ延出させその後端部をリヤパイプに当接させて、後輪の跳ね上げる水や泥に対する吸入ダクトの遮蔽部としたことを特徴とする。
【０００５】
第２の発明は、上記第１の発明において、エアクリーナケースカバーのさらに外側から吸入ダクトを覆う外カバーを設けるとともに、この外カバーを車体フレームへ着脱自在に取付け、かつ車体フレームと外カバーの間に吸入ダクトへ外気を導入するための間隙を設けたことを特徴とする。
【０００６】
【発明の効果】
第１の発明によれば、リヤフェンダを後輪の略後半側だけを覆うように設けても、後輪で跳ね上げられた水や泥が前方のエアクリーナへ多量にかかるようになるが、エアクリーナケースカバーの一部を上方及び後方へ延長して遮蔽部としたので、水や泥が吸入ダクトへ入りにくくなる。
【０００７】
その結果、遮蔽部として専用の別部材を用いることなく、エアクリーナケースカバーの一部を使って簡単かつ安価にできる。また、リヤフェンダを後半側のみとして従来の約半分にしても、エアクリーナの性能に影響なく、それだけ車体重量を軽量にできる。
【０００８】
第２の発明によれば、外カバーを設けて吸入ダクトを覆ったので、吸入ダクトに対する水や泥の侵入を防止できる。しかも、外カバーを取付ける車体フレームとの間に間隙を設けたので、この間隙から外気を吸入ダクトへ導入できる。
【０００９】
【発明の実施の形態】
以下、図面に基づいて一実施例を説明する。
図１は図４の１−１線断面図、図２は同２−２線断面図、図３は実施例のエアクリーナを取付けた自動２輪車の車体要部側面図、図４は外カバーの取付状態を車体側面側から拡大して示す図、図５は同部を車体前方から示す図、図６は図４の６−６線拡大断面図である。
【００１０】
まず、図３により本実施例のエアクリーナを設けた自動２輪車の概要を説明する。この自動２輪車の車体フレームは、車体中心に沿って一本で配設されたメインパイプ１と、その後端部から左右へ別れて下方へ延びるセンターパイプ２と、センターパイプ２の上部から左右一対で後方へ延出するシートレール３と、センターパイプ２の下部とシートレール３の中間部を斜めに連結する左右一対のリヤパイプ４とで構成される。
【００１１】
センターパイプ２、シートレール３及びリヤパイプ４で囲まれた側面視三角形状の空間内にはエアクリーナ５が配置され、前部をコンチューブ（図示省略）を介して気化器と１０と結合し、後部はシートレール３へ締結され、上部は一部がシートレール３へ下方から当てつけ、下部はクッションラバー３５を介してオイルタンク３６の上に乗るようにして車体フレーム側へ支持されている。
【００１２】
このエアクリーナ５は外カバー６を有し、センターパイプ２へ取付けられるとともに（詳細後述）、後端部に設けられた突起７をエアクリーナ本体側の差し込み部８へ差し込み結合し、かつこの係合部よりやや前方位置でキーロック９により本体側へロックされる。
【００１３】
エアクリーナ５で浄化された清浄空気は、前方の気化器１０へ供給され、ここで混合気となりエンジン１１の吸気ポートへ吸入される。
【００１４】
メインパイプ１の上方には燃料タンク１２が支持され、シートレール３の上方にはシート１３が支持される。さらに、シートレール３の後端部にはリヤフェンダ１４が取付けられている。
【００１５】
このリヤフェンダ１４は、下方にある後輪１５の上方にてその略後半分側のみを覆うよう設けられ、その前端部はシート１３の後端部下方へ重なっている。エアクリーナ５は後輪１５の前方に近接して位置する。
【００１６】
次に、図１，図２及び図４により、エアクリーナの詳細構造を説明する。エアクリーナ５はエアクリーナケース２０を備え、その内部に設けた筒形のエアクリーナエレメント２１により、ダーティルーム２２とクリーンルーム２３に分離している。
【００１７】
クリーンルーム２３は気化器１０へ接続するとともに、ダーティルーム２２は吸入ダクト２４から外気を吸入するようになっている。
【００１８】
吸入ダクト２４は、エアクリーナケース２０の開口部を閉塞するエアクリーナケースカバー２５に取付けられており、エアクリーナケースカバー２５でエアクリーナケース２０を閉じるとき、同時にダーティルーム２２内へ一端部が臨む。
【００１９】
エアクリーナケースカバー２５のうち、後部側にはエアクリーナケース２０よりも長く後方へ延出する遮蔽部２６が設けられ、その後端部はリヤパイプ４に当接し、後輪１５の駆動回転により前方へ跳ね飛ばされる水や泥が吸入ダクト２４の開口部へ到達しないようにしている。
【００２０】
また、エアクリーナケースカバー２５のうち上部側にも、上方へ延出してシートレール３へ当接する遮蔽部２７が一体に設けられ（図２）、エアクリーナ５上方から水や泥が吸入ダクト２４側へ侵入しにくくなっている。
【００２１】
さらに、吸入ダクト２４の上方を覆うように外側方へ延出する棚状部２８も一体に形成され、この上に工具類２８ａを支持できるようになっている。
【００２２】
さらに、吸入ダクト２４の周囲はエアクリーナケースカバー２５とは別体の外カバー６によって覆われている。外カバー６の前端部及び上端部は、センターパイプ２及びシートレール３の側面上に重なり、かつセンターパイプ２及びシートレール３との間に間隙２９が形成され、ここから外気を吸入ダクト２４の開口端へ導入するようになっている。
【００２３】
但し、前端部側では、エアクリーナケース２０とセンターパイプ２の間にも間隙が形成され、ここからも外気を導入できるようになっている。
【００２４】
なお、外カバー６の後端部は、リヤパイプ４と重ならず、その前方側で遮蔽部２６近くまで内方へ入り込んでいる。図４中の符号５ａはエアークリーナケース２０の後部に設けられたリブであり、シートレール３のステー３ａへ締結されている。また５ｂはエアークリーナケース２０と一体に上方へ突出して形成されたリブであり、上端部がシートレール３の下面へ当接する。
【００２５】
次に、外カバー６の取付構造を説明する。図５及び図６に示すように、センターパイプ２の側面には線状部材３０が上下方向へ長く配設され、その中間部を溶接等で取付けられ、その上下部分はセンターパイプ２から浮き上がった係止部３１になっている。
【００２６】
一方、外カバー６の前端部内側上下には、先端が後方へ曲げ返されたフック３２が一体に形成され、係止部３１へ前方から係合するようになっている。
【００２７】
そこで、フック３２を係止部３１の前方位置となるように外カバー６を車体側方へ被せ、外カバー６全体を後方へずらせば、フック３２が係止部３１へ係合し、、外カバー６の前端部がセンターパイプ２側へ係止される。
【００２８】
続いて、外カバー６の後端部に車体内方へ向かって突出するように一体に設けられた差し込み突起７を、予めエアクリーナケース２０側へ一体に設けられている取付部８のグロメットへ差し込めば、外カバー６の後端部側もエアクリーナケース２０へ係止される。
【００２９】
その後、図５に示すように、キーロック９をキー３３で操作すれば、外カバー６をエアクリーナケース２０側へロックできる。但し、閉じるときはキー操作不要でロックし、開くときのみキー操作するようにしてもよい。
【００３０】
また、外カバー６を開くときは図６に示すようにフック３２が係止部３１へ係合し、これを軸として外カバー６が回動可能になっている。
【００３１】
次に、本実施例の作用を説明する。図１及び図２に示すように、後輪１５が駆動回転すると、水や泥３５が前方へ跳ね飛ばされが、この水や泥３５は遮蔽部２６及び遮蔽部２７により吸入ダクト２４の開口部へ到達しにくくなっている。
【００３２】
このため、エアクリーナエレメント２１の目詰まりが生じにくくなり、耐久性を向上できる。しかも、リヤフェンダ１４を後輪１５の略後半部側のみを覆うようにすることにより、本来エアクリーナ５へかかる水や泥３５の量が多くなるにもかかわらず、これらを有効に阻止できる。
【００３３】
なお、吸入ダクト２４に対する水や泥３５の侵入阻止は外カバー６によっても実現されている。
【００３４】
また、この遮蔽部２６、２７をエアクリーナケースカバー２５と一体に形成することにより、特別な専用部材を設けないで済むので、部品点数を削減でき、エアクリーナ５単体で構成できるため、自由度も高くなる。そのうえ、リヤフェンダ１４を従来の略半分程度にしてもよいので、車体重量の軽量化に貢献できる。
【００３５】
さらに、外カバー６の前端部をセンターパイプ２に取付けた線状部材３０を介して係合により取付けることができ、この線状部材３０は単純な線材を所定形状に折り曲げてセンターパイプ２へ溶接するだけで簡単に構成でき、かつ係合構造が簡単になる。

BACKGROUND OF THE INVENTION
The present invention relates to an air cleaner device for a motorcycle.
[0002]
[Prior art]
For an air cleaner for a motorcycle, it is necessary to take into consideration that water and mud splashed up from the rear wheel and the like do not enter the suction duct. For example, in Japanese Utility Model Publication No. 56-35422, a front fender for rear wheels is provided. The part is extended forward sufficiently long and an air cleaner is provided here to shield the suction duct at the front end of the rear fender.
[0003]
[Problems to be solved by the invention]
In order to prevent water and mud from entering the suction duct, it is necessary to provide some sort of shielding. In the above-described conventional example, the front extension portion of the rear fender corresponds to this. However, if this is done, the number of parts and the weight increase, so a structure that eliminates the need for such a special shield is desired. In particular, when a rear fender of the type in which the first half side is omitted is adopted, water and mud are easily applied to the air cleaner. The present application satisfies this requirement.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, a first invention relating to an air cleaner device for a motorcycle according to the present application includes: a main pipe disposed in a front-rear direction; a center pipe extending downward from a rear end portion of the main pipe; The center rail is composed of a seat rail that extends rearward from the upper part of the center pipe and a rear pipe that obliquely connects the seat rail and the lower part of the center pipe, and the rear fender is provided so as to cover only the rear half of the rear wheel. In a motorcycle provided with an air cleaner in front of the rear wheel and the rear pipe and on one side surface of the vehicle body in the left-right direction,
An air cleaner case cover that covers the opening of the air cleaner case and to which the suction duct is attached, and an outer cover that covers the suction duct from the outside of the air cleaner case cover are provided, and a part of the air cleaner case cover is located behind the edge of the opening. The rear end of the rear pipe is brought into contact with the rear pipe, and the suction duct is shielded against the water and mud splashing up the rear wheel.
[0005]
According to a second invention, in the first invention, an outer cover for covering the suction duct is provided from the outer side of the air cleaner case cover, the outer cover is detachably attached to the body frame, and between the body frame and the outer cover. Is provided with a gap for introducing outside air into the suction duct.
[0006]
【The invention's effect】
According to the first aspect of the invention, even if the rear fender is provided so as to cover only the rear half of the rear wheel, a large amount of water and mud splashed by the rear wheel are applied to the front air cleaner. Since a part of the cover is extended upward and rearward to form a shielding part, it is difficult for water and mud to enter the suction duct.
[0007]
As a result, it is possible to easily and inexpensively use a part of the air cleaner case cover without using a dedicated separate member as the shielding portion. Moreover, even if the rear fender is only on the rear side and is about half that of the conventional one, the weight of the vehicle body can be reduced by that amount without affecting the performance of the air cleaner.
[0008]
According to the second invention, since the outer cover is provided to cover the suction duct, water and mud can be prevented from entering the suction duct. In addition, since a gap is provided between the vehicle body frame to which the outer cover is attached, outside air can be introduced into the suction duct from this gap.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment will be described below with reference to the drawings.

FIG. 5 is an enlarged view from the side of the vehicle body, FIG. 5 is a view showing the same portion from the front of the vehicle body, and FIG.
[0010]
First, the outline of the motorcycle provided with the air cleaner of this embodiment will be described with reference to FIG. The body frame of the motorcycle includes a main pipe 1 that is arranged along the center of the body, a center pipe 2 that extends from the rear end to the left and right, and a pair of left and right from the upper part of the center pipe 2. The seat rail 3 extends rearward, and a pair of left and right rear pipes 4 that obliquely connect a lower portion of the center pipe 2 and an intermediate portion of the seat rail 3.
[0011]
An air cleaner 5 is arranged in a triangular space surrounded by the center pipe 2, the seat rail 3, and the rear pipe 4, and the front part is connected to the carburetor 10 via a contube (not shown), and the rear part is Fastened to the seat rail 3, a part of the upper part is applied to the seat rail 3 from below, and the lower part is supported on the body frame side so as to ride on the oil tank 36 via the cushion rubber 35.
[0012]
This air cleaner 5 has an outer cover 6 and is attached to the center pipe 2 (details will be described later), and a projection 7 provided at the rear end portion is inserted and connected to an insertion portion 8 on the air cleaner body side, and from this engagement portion It is locked to the main body by a key lock 9 at a slightly forward position.
[0013]
The clean air purified by the air cleaner 5 is supplied to the front carburetor 10, where it is mixed and sucked into the intake port of the engine 11.
[0014]
A fuel tank 12 is supported above the main pipe 1, and a seat 13 is supported above the seat rail 3. Further, a rear fender 14 is attached to the rear end portion of the seat rail 3.
[0015]
The rear fender 14 is provided so as to cover only the substantially rear half side above the rear wheel 15 located below, and the front end thereof overlaps the rear end of the seat 13. The air cleaner 5 is located close to the front of the rear wheel 15.
[0016]
Next, the detailed structure of the air cleaner will be described with reference to FIGS. The air cleaner 5 includes an air cleaner case 20 and is separated into a dirty room 22 and a clean room 23 by a cylindrical air cleaner element 21 provided therein.
[0017]
The clean room 23 is connected to the vaporizer 10, and the dirty room 22 sucks outside air from the suction duct 24.
[0018]
The suction duct 24 is attached to an air cleaner case cover 25 that closes an opening of the air cleaner case 20. When the air cleaner case 20 is closed by the air cleaner case cover 25, one end portion faces the dirty room 22 at the same time.
[0019]
The air cleaner case cover 25 is provided with a shielding portion 26 that extends rearward longer than the air cleaner case 20 on the rear side, the rear end portion abuts against the rear pipe 4, and jumps forward by the driving rotation of the rear wheel 15. Water or mud is prevented from reaching the opening of the suction duct 24.
[0020]
Further, a shielding portion 27 that extends upward and contacts the seat rail 3 is integrally provided on the upper side of the air cleaner case cover 25 (FIG. 2), and water and mud from the upper side of the air cleaner 5 to the suction duct 24 side. It is hard to penetrate.
[0021]
Further, a shelf-like portion 28 that extends outward so as to cover the upper portion of the suction duct 24 is integrally formed, and the tools 28a can be supported thereon.
[0022]
Furthermore, the periphery of the suction duct 24 is covered with an outer cover 6 that is separate from the air cleaner case cover 25. The front end portion and the upper end portion of the outer cover 6 overlap the side surfaces of the center pipe 2 and the seat rail 3, and a gap 29 is formed between the center pipe 2 and the seat rail 3. To be introduced.
[0023]
However, on the front end side, a gap is also formed between the air cleaner case 20 and the center pipe 2 so that outside air can be introduced also from here.
[0024]
Note that the rear end portion of the outer cover 6 does not overlap the rear pipe 4 and enters inward to the vicinity of the shielding portion 26 on the front side thereof. Reference numeral 5 a in FIG. 4 is a rib provided at the rear portion of the air cleaner case 20, and is fastened to the stay 3 a of the seat rail 3. Reference numeral 5b denotes a rib formed so as to protrude upward integrally with the air cleaner case 20, and the upper end of the rib contacts the lower surface of the seat rail 3.
[0025]
Next, the mounting structure of the outer cover 6 will be described. As shown in FIGS. 5 and 6, a linear member 30 is vertically disposed on the side surface of the center pipe 2, and an intermediate portion thereof is attached by welding or the like, and the upper and lower portions are raised from the center pipe 2. It is part 31.
[0026]
On the other hand, hooks 32 whose front ends are bent back are formed integrally on the upper and lower sides of the front end portion of the outer cover 6 so as to be engaged with the locking portion 31 from the front.
[0027]
Therefore, if the outer cover 6 is covered to the side of the vehicle body so that the hook 32 is positioned in front of the locking portion 31 and the entire outer cover 6 is shifted rearward, the hook 32 engages with the locking portion 31 and The front end portion of the cover 6 is locked to the center pipe 2 side.
[0028]
Subsequently, the insertion protrusion 7 that is integrally provided at the rear end of the outer cover 6 so as to protrude inward of the vehicle body is inserted into the grommet of the attachment portion 8 that is integrally provided in advance on the air cleaner case 20 side. For example, the rear end side of the outer cover 6 is also locked to the air cleaner case 20.
[0029]
Thereafter, as shown in FIG. 5, the outer cover 6 can be locked to the air cleaner case 20 side by operating the key lock 9 with the key 33. However, the key operation may be locked without closing when closing, and the key operation may be performed only when opening.
[0030]
When the outer cover 6 is opened, as shown in FIG. 6, the hook 32 engages with the locking portion 31, and the outer cover 6 can be rotated about this.
[0031]
Next, the operation of this embodiment will be described. As shown in FIGS. 1 and 2, when the rear wheel 15 is driven and rotated, water and mud 35 are splashed forward, and the water and mud 35 are opened by the shielding part 26 and the shielding part 27 in the opening portion of the suction duct 24. It is difficult to reach.
[0032]
For this reason, the air cleaner element 21 is less likely to be clogged, and durability can be improved. In addition, by covering the rear fender 14 only on the substantially rear half side of the rear wheel 15, even though the amount of water and mud 35 originally applied to the air cleaner 5 increases, these can be effectively prevented.
[0033]
It should be noted that water and mud 35 are prevented from entering the suction duct 24 by the outer cover 6.
[0034]
Further, by forming the shielding portions 26 and 27 integrally with the air cleaner case cover 25, it is not necessary to provide a special dedicated member. Therefore, the number of parts can be reduced, and the air cleaner 5 can be configured as a single unit. Become. In addition, since the rear fender 14 may be about half of the conventional size, it can contribute to a reduction in the weight of the vehicle body.
[0035]
Further, the front end portion of the outer cover 6 can be attached by engagement via a linear member 30 attached to the center pipe 2, and the linear member 30 is simply bent into a predetermined shape and welded to the center pipe 2. And can be easily configured, and the engagement structure is simplified.
