Description

この発明は、風防装置を備えた自動二輪車等の鞍乗り型車両に関する。   The present invention relates to a saddle-ride type vehicle such as a motorcycle provided with a windshield device.

従来、防風効果を得るために車両の前方にスクリーンを備えたものが良く知られている(例えば、特許文献1,2参照。)。
特許文献1によれば、スクリーンの下側に開口部を設けて、その開口部からカウル内側に走行風を導くことにより、スクリーンによる防風効果を得つつ、風切り音の低減を図っている。
また、特許文献2によれば、走行風を車両上方に吹き出すダクトをスクリーンとして用いることにより、スクリーン高さを抑えた上で防風効果を得つつ、かつ別途ダクトによりカウル内側に走行風を導くことで、カウル裏側(後方側)が負圧になることを緩和している。
2. Description of the Related Art Conventionally, it is well known that a screen is provided in front of a vehicle in order to obtain a windproof effect (see, for example, Patent Documents 1 and 2).
According to Patent Document 1, an opening is provided on the lower side of the screen, and wind is guided from the opening to the inside of the cowl, thereby reducing wind noise while obtaining a windproof effect by the screen.
Further, according to Patent Document 2, a duct that blows the traveling wind upwards of the vehicle is used as a screen, so that the wind is prevented while keeping the height of the screen, and the traveling wind is separately guided inside the cowl by the duct. Therefore, the back side (rear side) of the cowl is alleviated from becoming negative pressure.

特開2001−10573号公報JP 2001-10573 A 特開2007−62616号公報JP 2007-62616 A

ところで、カウル裏側の負圧を小さくするためには、スクリーンの裏側でかつ車幅方向中央寄りに走行風を導くと有効である。
しかし、スクリーン用のダクトと負圧補正用のダクトとを共に車幅方向中央寄りに設けると、スクリーン周りの前後厚さが増加し、カウル設計自由度を減少させるという課題がある。一方、各ダクトの入口を車幅方向に並べると、各ダクトの出口を車幅方向中央寄りに配置するために、ダクトを合流させる等の工夫が必要であるが、ダクトの合流地点では乱流や負圧が発生し易く、スクリーン効果を減少させる可能性がある。
By the way, in order to reduce the negative pressure on the back side of the cowl, it is effective to guide the traveling wind on the back side of the screen and closer to the center in the vehicle width direction.
However, if both the screen duct and the negative pressure correcting duct are provided closer to the center in the vehicle width direction, there is a problem that the front and rear thickness around the screen increases and the degree of freedom in designing the cowl decreases. On the other hand, when the inlets of the ducts are arranged in the vehicle width direction, it is necessary to devise measures such as merging the ducts so that the outlets of the ducts are arranged closer to the center in the vehicle width direction. And negative pressure is likely to occur, which may reduce the screen effect.

そこでこの発明は、風防装置を備えた鞍乗り型車両において、スクリーンに複数のダクトを設けた上でスクリーン周りの前後厚さを抑え、かつダクトの合流部分での整流効果を高めることを目的とする。   Therefore, the present invention aims to increase the rectifying effect at the confluence of the ducts in a saddle-ride type vehicle equipped with a windshield device, by providing a plurality of ducts on the screen and suppressing the thickness around the screen. To do.

In the following description, the directions such as front, rear, left and right are the same as those in the vehicle unless otherwise specified. In the figure, the arrow FR indicates the front of the vehicle, the arrow LH indicates the left side of the vehicle, and the arrow UP indicates the upper side of the vehicle.

図1は、この発明の一実施例である低床フロア2を有するスクータ型車両としての自動二輪車(鞍乗り型車両)1を示す。自動二輪車1の前輪3はテレスコピック式のフロントフォーク4に軸支され、該フロントフォーク4はステアリングステム5を介して車体フレーム6前端のヘッドパイプ7に操舵可能に枢支される。車体フレーム6は、ヘッドパイプ7から後下がりに延びた後に屈曲してさらに後上がりに延びるメインパイプ8を有する。ステアリングステム5の上端部には、バー型の操向ハンドル9が取り付けられる。   FIG. 1 shows a motorcycle (saddle-ride type vehicle) 1 as a scooter type vehicle having a low floor 2 according to an embodiment of the present invention. The front wheel 3 of the motorcycle 1 is pivotally supported by a telescopic front fork 4, and the front fork 4 is pivotally supported by a head pipe 7 at the front end of the vehicle body frame 6 via a steering stem 5. The vehicle body frame 6 includes a main pipe 8 that extends from the head pipe 7 to the rear and lower and then bends and extends further to the rear. A bar-type steering handle 9 is attached to the upper end portion of the steering stem 5.

車体フレーム6の後部には、スイングユニット10がその前端側を中心に揺動可能に枢支される。スイングユニット10は、エンジン11及び動力伝達機構12を一体に構成してなり、その後端側の出力軸には駆動輪である後輪13が取り付けられる。スイングユニット10の後端部と車体フレーム6の後端部との間には、緩衝用のリアクッション14が配設される。   A swing unit 10 is pivotally supported at the rear portion of the vehicle body frame 6 so as to be swingable around its front end side. The swing unit 10 comprises an engine 11 and a power transmission mechanism 12 integrally, and a rear wheel 13 as a drive wheel is attached to the output shaft on the rear end side. A shock absorbing rear cushion 14 is disposed between the rear end portion of the swing unit 10 and the rear end portion of the vehicle body frame 6.

車体フレーム6は、主に合成樹脂からなるボディカバー15により覆われる。ボディカバー15は、車体フレーム6の前部をその前方から左右側方に渡って覆うフロントカバー(フロントカウル)16と、該フロントカバー16の下方に連続して車体フレーム6の下部を覆うアンダーカバー17と、車体フレーム6の後部を覆うリアカバー18と、フロントカバー16の後部からアンダーカバー17の上部に渡る部位を覆うフロアカバー19とを主になる。   The body frame 6 is covered with a body cover 15 mainly made of synthetic resin. The body cover 15 includes a front cover (front cowl) 16 that covers the front portion of the body frame 6 from the front to the left and right sides, and an under cover 17 that covers the lower portion of the body frame 6 continuously below the front cover 16. The rear cover 18 that covers the rear part of the vehicle body frame 6 and the floor cover 19 that covers the part extending from the rear part of the front cover 16 to the upper part of the under cover 17 are mainly used.

リアカバー18の上方には、該リアカバー18内の物品収容室(図示略)を開閉可能な乗員(運転者及び後部搭乗者)用のシート20が配設される。シート20の前部に着座した乗員(運転者)Jは、操向ハンドル9の左右グリップ部に手をかけ、フロアカバー19の左右上面に足を載せた運転姿勢をとる。このとき、乗員Jの正面(前方)にはフロントカバー16が位置し、該フロントカバー16が乗員Jへの走行風圧を低減する。なお、図中符号21はフロントカバー16の前端部に配設されるヘッドランプを、符号22はフロントカバー16の左右両側に配設されるサイドミラーをそれぞれ示す。   Above the rear cover 18, a seat 20 for passengers (drivers and rear passengers) that can open and close an article storage chamber (not shown) in the rear cover 18 is disposed. An occupant (driver) J seated on the front portion of the seat 20 puts his hands on the left and right grip portions of the steering handle 9 and takes a driving posture with his feet on the left and right upper surfaces of the floor cover 19. At this time, the front cover 16 is located in front (front) of the occupant J, and the front cover 16 reduces the traveling wind pressure applied to the occupant J. In the figure, reference numeral 21 denotes a headlamp disposed at the front end portion of the front cover 16, and reference numeral 22 denotes side mirrors disposed on the left and right sides of the front cover 16.

フロントカバー16は操向ハンドル9の前方に位置し、その下部は左右幅を広げて操向ハンドル9の左右グリップ周り(乗員Jの前腕周り)への防風効果を高める一方、フロントカバー16の上部は下部に対して比較的左右幅を狭めて乗員Jの正面に立ち上がる(図3,11参照)。このフロントカバー16の上部が、例えばポリカーボネイト等の透明又は半透明の透過性樹脂を主にスクリーン25として構成される。   The front cover 16 is located in front of the steering handle 9, and the lower part of the front cover 16 increases the width of the left and right to increase the windproof effect around the left and right grips of the steering handle 9 (around the forearm of the occupant J). Stands up in front of the occupant J with a relatively narrow left-right width with respect to the lower part (see FIGS. 3 and 11). The upper portion of the front cover 16 is mainly composed of a transparent or translucent transparent resin such as polycarbonate as the screen 25.

図2,3を併せて参照し、スクリーン25は、フロントカバー16の上部における後上がりの外面を形成する板状のフロントスクリーン26と、該フロントスクリーン26の後方に離間して配される板状のリアスクリーン28と、これらフロントスクリーン26及びリアスクリーン28間に配される板状のセンタスクリーン27とを有してなる。   2 and 3, the screen 25 includes a plate-like front screen 26 that forms an outer surface that rises rearward in the upper portion of the front cover 16, and a plate-like shape that is spaced apart from the rear of the front screen 26. The rear screen 28 and a plate-like center screen 27 disposed between the front screen 26 and the rear screen 28 are provided.

このスクリーン25を通じても、乗員Jが車両前方を視認可能であるが、スクリーン25(フロントカバー16)の上縁高さは、乗員Jの前方視界を遮らない程度(胸部高さ程度)とされる。これは、フロントカバー16が車両前方からの走行風を上方に案内する後上がりのエアダクト31を有し、スクリーン高さを抑えた上でその後方の乗員Jへの風防効果を高めているからである。   The occupant J can also visually recognize the front of the vehicle through the screen 25, but the upper edge height of the screen 25 (front cover 16) is set so as not to obstruct the front view of the occupant J (chest height). . This is because the front cover 16 has a rear-up air duct 31 that guides the traveling wind from the front of the vehicle upward, and suppresses the screen height and enhances the windshield effect on the passenger J behind it. is there.

図5を併せて参照し、フロントカバー16におけるスクリーン25を除く部位は、例えばABS等の不透明樹脂からなるカバーインナ51及びインナシェル61を主に構成される。カバーインナ51及びインナシェル61はそれぞれ上下厚さを抑えた扁平状をなし、これらが互いに後上がりに傾斜するように配置され、かつカバーインナ51上にインナシェル61が重なることで、これらが中空のモナカ構造体を形成する。そして、これらカバーインナ51及びインナシェル61の他に、センタスクリーン27及びリアスクリーン28を用いることで、フロントカバー16に複数のエアダクトの空気流路が形成される。   Referring also to FIG. 5, a portion of the front cover 16 excluding the screen 25 mainly includes a cover inner 51 and an inner shell 61 made of an opaque resin such as ABS. The cover inner 51 and the inner shell 61 each have a flat shape with a reduced vertical thickness, are arranged so as to incline toward each other rearward, and the inner shell 61 overlaps the cover inner 51 so that they are hollow. The monaca structure is formed. In addition to the cover inner 51 and the inner shell 61, the center screen 27 and the rear screen 28 are used to form air flow paths of a plurality of air ducts in the front cover 16.

フロントカバー16は、車両前方からの走行風を導いて車両上方へ吹き出す前記エアダクト(以下、第一エアダクトという)31と、前記走行風を導いて車両後方(フロントカバー16後方(裏側)の乗車空間)に吹き出す第二エアダクト32と、フロントスクリーン26の後方(裏側)に形成されて前記走行風を所定の方向へ導く第三エアダクト33とを備える。   The front cover 16 guides the traveling wind from the front of the vehicle and blows it upwards of the vehicle. The front cover 16 guides the traveling wind to the rear of the vehicle (rear side of the front cover 16 (back side)). ) And a third air duct 33 formed behind the front screen 26 to guide the traveling wind in a predetermined direction.

第一エアダクト31は全体的に後上がりに傾斜し、かつ後側(上側)ほど傾斜を急にするように側面視で斜め下後方(車内側)に凸の湾曲状に設けられる。すなわち、第一エアダクト31は、車両外方から見て斜め下後方に凹むように設けられる。   The first air duct 31 is inclined in a rearwardly upward manner and is provided in a convexly curved shape obliquely downward and rearward (inner side of the vehicle) in a side view so that the inclination is steeper toward the rear side (upper side). That is, the first air duct 31 is provided so as to be recessed obliquely downward and rearward when viewed from the outside of the vehicle.

なお、第一エアダクト31の前方に取り付くフロントスクリーン26も全体的に後上がりに傾斜するが、該フロントスクリーン26は後側(上側)ほど傾斜を緩めるように側面視で斜め上前方(車外側)に凸の湾曲状に設けられる。すなわち、フロントスクリーン26は、車両外方から見て斜め上前方に膨出するように設けられる。   Note that the front screen 26 attached to the front of the first air duct 31 is also generally inclined rearwardly upward, but the front screen 26 is obliquely upward and forward (outside of the vehicle) as viewed from the side so that the inclination is reduced toward the rear side (upper side). Are provided in a convex curved shape. That is, the front screen 26 is provided so as to bulge obliquely upward and forward as viewed from the outside of the vehicle.

Referring also to FIG. 13, the left and right communication ports 66 are provided in front of the alignment portion 67 in the inner shell 61 (outside of the upper first air flow path 37 (front side), in the third air duct 33). A left and right second communication port 68 having a slit shape along the front edge is provided.
In addition, a third communication port 69 having a long rectangular shape in the front and rear is formed in the left and right central portion of the rear portion of the inner shell 61. The third communication port 69 has a tapered inner peripheral wall 69 extending from the inner peripheral edge so as to reduce the opening downward.

第三連通口69の上方(上第一空気流路37内)には前記合流部Gが位置し、該合流部Gにおいて左右下第一空気流路36から左右連通口66を介して流入した走行風が互いに斜めに合流することで、この合流部Gの直下位置(第三連通口69の上方位置)では、大気圧に対する負圧(低圧)が生じ易くなると共に、左右の走行風がぶつかるため乱流が発生し易い。   Above the third communication port 69 (in the upper first air flow path 37), the merging portion G is located, and flows into the merging portion G from the left and right lower first air flow channels 36 via the left and right communication ports 66. When the traveling winds merge with each other at an angle, a negative pressure (low pressure) with respect to the atmospheric pressure is likely to be generated at a position directly below the merging portion G (an upper position of the third communication port 69), and the traveling winds on the left and right collide with each other. Therefore, turbulent flow is likely to occur.

しかし、合流部Gの下方に第三連通口69を設けることで、前記負圧が生じたとしても、後第二空気流路41との圧力差により第二エアダクト32内の走行風が合流部G内に吸入され、もって前記負圧が解消されると共に乱流を低減でき、第一エアダクト31内の整流化が図れる。
すなわち、前記負圧の発生による第一エアダクト31内の空気抵抗が抑えられ、第一空気吹き出し口35からの走行風の吹き出しを良好にして高いスクリーン効果が得られる。
However, by providing the third communication port 69 below the merging portion G, even if the negative pressure is generated, the traveling wind in the second air duct 32 is caused by the pressure difference with the rear second air flow path 41. Inhaled into G, the negative pressure is eliminated and turbulence can be reduced, and rectification in the first air duct 31 can be achieved.
That is, the air resistance in the first air duct 31 due to the generation of the negative pressure is suppressed, and the blowing of the traveling wind from the first air blowing port 35 is made good and a high screen effect is obtained.

ここで、第二空気吹き出し口39には可動式のルーバー39aが設けられ(図2,12参照)、第二空気吹き出し口39からの走行風の吹き出し量や吹き出し角度を調整可能である。なお、鍔部81aの下面(第二空気吹き出し口39の直下)には、複数の固定ルーバー81cを有して走行風を斜め下後方に向けて吹き出し可能な第四空気吹き出し口81bが設けられる。   Here, the second air outlet 39 is provided with a movable louver 39a (see FIGS. 2 and 12), and the amount and angle of the blowing air from the second air outlet 39 can be adjusted. A fourth air outlet 81b having a plurality of fixed louvers 81c and capable of blowing the traveling wind diagonally downward and rearward is provided on the lower surface of the flange 81a (just below the second air outlet 39). .

図2,4を参照し、第一エアダクト31の下部(第一湾曲部46)の車外側(内周側)に位置する前壁(湾曲内周壁)は、前記インナシェル61を主に構成され、第一エアダクト31の上部(第一立ち上がり部47)の車外側に位置する前壁は、前記センタスクリーン27を主に構成される。第一エアダクト31の下部前壁は第三エアダクト33の下部後壁でもあり、第一エアダクト31の上部前壁は第三エアダクト33の上部後壁でもある。   2 and 4, the front wall (curved inner peripheral wall) located on the vehicle outer side (inner peripheral side) of the lower portion (first curved portion 46) of the first air duct 31 is mainly composed of the inner shell 61. The front wall located on the vehicle outer side of the upper part (first rising part 47) of the first air duct 31 mainly comprises the center screen 27. The lower front wall of the first air duct 31 is also the lower rear wall of the third air duct 33, and the upper front wall of the first air duct 31 is also the upper rear wall of the third air duct 33.

また、第一エアダクト31の下部の車内側(外周側)に位置する後壁(湾曲外周壁)は、前記カバーインナ51を主に構成され、第一エアダクト31の上部の車内側に位置する後壁は、前記リアスクリーン28を主に構成される。   A rear wall (curved outer peripheral wall) located on the inner side (outer peripheral side) of the lower part of the first air duct 31 is mainly composed of the cover inner 51 and is located on the inner side of the upper part of the first air duct 31. The wall is mainly composed of the rear screen 28.

第一及び第三エアダクト31,33の特に各湾曲部46,48において、前記前壁及び後壁の前面側(各湾曲部46,48の外周側)では、車両前方からの走行風の流れを上方に曲げることから、大気圧に対して高圧になり易いが、前記前壁の後面側(各湾曲部46,48の内周側)では逆に、大気圧に対して低圧(負圧)になり易い。   In the curved portions 46 and 48 of the first and third air ducts 31 and 33, on the front side of the front wall and the rear wall (the outer peripheral side of the curved portions 46 and 48), the flow of traveling wind from the front of the vehicle Since it is bent upward, it tends to be high pressure with respect to atmospheric pressure. However, on the rear side of the front wall (inner peripheral side of each curved portion 46, 48), conversely, it is low pressure (negative pressure) with respect to atmospheric pressure. Easy to be.

しかし、第一エアダクト31の湾曲部46に前記第二連通口68を設けることで、前記負圧が生じたとしても、第三空気流路44との圧力差により第三エアダクト33内の走行風が第一エアダクト31内に吸入され、もって前記負圧が解消される。
これにより、前記負圧の発生による第一エアダクト31内の空気抵抗が抑えられ、第一空気吹き出し口35からの走行風の吹き出しを良好にして高いスクリーン効果が得られる。
However, by providing the second communication port 68 in the curved portion 46 of the first air duct 31, even if the negative pressure is generated, the traveling wind in the third air duct 33 is caused by the pressure difference with the third air flow path 44. Is sucked into the first air duct 31 and the negative pressure is eliminated.
As a result, the air resistance in the first air duct 31 due to the generation of the negative pressure is suppressed, and the blowing of the traveling wind from the first air blowing port 35 is improved, and a high screen effect is obtained.

図5,8,13を参照し、フロントスクリーン26は、その左右中間部が左右方向と略平行な平板状の平坦部26aとされることで、乗員Jから見た車両前方視の歪みを抑える一方、左右両側部が斜め後左右外側に回り込むように湾曲する湾曲部26bとされることで、車両前方からの走行風を左右外側に受け流し易くして乗員Jの肩や上腕周りに対する防風効果を高めている。   Referring to FIGS. 5, 8, and 13, the front screen 26 has a flat middle portion 26 a that is substantially parallel to the left-right direction at the left and right intermediate portions, thereby suppressing distortion of the vehicle front view as viewed from the passenger J. On the other hand, the curved portions 26b that bend so that the left and right sides turn obliquely to the left and right outside can be easily received by the vehicle wind from the front of the vehicle to the left and right sides, thereby providing a windproof effect on the shoulders and upper arms of the occupant J. It is increasing.

図5,8,11を参照し、フロントスクリーン26は、その下部両側がインナシェル61に膨出形成された前記台座部62aにそれぞれ上下一対のビス又はクリップ等を用いて固定され、もってインナシェル61に一体的に支持される。フロントスクリーン26のインナシェル61への取り付け部(台座部62a)周辺は、前記フロントセンターカバー73の両側部により車外側から覆われており、該取り付け部を車外側に露出させずに外観性(意匠性)を良好に保つと共に、フロントスクリーン26上の走行風の流れを阻害し難くしている。   Referring to FIGS. 5, 8, and 11, the front screen 26 is fixed to the pedestal portion 62 a, the lower side of which is bulged from the inner shell 61, using a pair of upper and lower screws or clips, and thus the inner shell. 61 is integrally supported. The periphery of the attachment portion (pedestal portion 62a) of the front screen 26 to the inner shell 61 is covered from the outside of the vehicle by both side portions of the front center cover 73, and the external appearance ( In addition to maintaining good design properties, the flow of the traveling wind on the front screen 26 is hardly inhibited.

フロントスクリーン26の外面に至った走行風は、前述の如く左右外側に受け流されると共に斜め上後方に受け流される。また、第三エアダクト33内に至った走行風は、第三空気吹き出し口43から上方に吹き出される。このような走行風の流れにより、第一空気吹き出し口35から吹き出す走行風によるスクリーン効果が高められる。   The traveling wind reaching the outer surface of the front screen 26 is received on the left and right outer sides as described above, and is also received obliquely upward and rearward. The traveling wind that has reached the inside of the third air duct 33 is blown upward from the third air outlet 43. Due to the flow of the traveling wind, the screen effect by the traveling wind blown from the first air outlet 35 is enhanced.

ところで、フロントスクリーン26の上部は他部品に支持されておらず、このフロントスクリーン26上部の左右両側部(湾曲部26b)の内周面と第一エアダクト31の上部(立ち上がり部47)の角部外面との間には、第三エアダクト33内の走行風の一部を湾曲部26bの内周面に沿って斜め後左右外側に吹き出し可能な開放部(隙間)84が形成される(図12,13参照)。この開放部84から走行風を吹き出すことでも、乗員Jの肩や上腕周りに対する防風効果が高められる。   By the way, the upper part of the front screen 26 is not supported by other parts, and the inner peripheral surface of the left and right side parts (curved part 26b) of the upper part of the front screen 26 and the corner part of the upper part (rise part 47) of the first air duct 31. Between the outer surface, there is formed an open portion (gap) 84 that allows a part of the traveling wind in the third air duct 33 to be blown obliquely rearward and left and right along the inner peripheral surface of the curved portion 26b (FIG. 12). , 13). By blowing the running wind from the opening 84, the windproof effect on the shoulder and upper arm circumference of the occupant J can be enhanced.

以上説明したように、上記実施例における自動二輪車1は、操向ハンドル9の前方にフロントカバー16(風防装置)を備えたものにおいて、前記フロントカバー16には、その前端部かつ車幅方向中心で車両前方に向けて開口して走行風を導く第二空気導入口38と、フロントカバー16の裏側で車両後方に向けて開口する第二空気吹き出し口39と、第二空気導入口38及び第二空気吹き出し口39を連通する第二エアダクト32(圧力調整ダクト)とを備えると共に、前記第二空気導入口38の左右にて車両前方に向けて開口する左右第一空気導入口34と、フロントカバー16の上端部かつ車幅方向中心で車両上方に向けて開口する第一空気吹き出し口35と、左右第一空気導入口34からの空気流路を合流部Gにて合流させて左右第一空気導入口34及び第一空気吹き出し口35を連通する第一エアダクト31とを備え、前記第一エアダクト31の合流部Gの下方に前記第二エアダクト32が配置され、前記合流部Gと第二エアダクト32との間にこれらを連通する第三連通口69が設けられるものである。   As described above, the motorcycle 1 in the above embodiment includes the front cover 16 (windshield device) in front of the steering handle 9, and the front cover 16 has a front end portion and a center in the vehicle width direction. The second air inlet 38 that opens toward the front of the vehicle and guides the traveling wind, the second air outlet 39 that opens toward the rear of the vehicle on the back side of the front cover 16, the second air inlet 38 and the second A second air duct 32 (pressure adjusting duct) that communicates with the two air outlets 39, a left and right first air inlet 34 that opens toward the front of the vehicle on the left and right of the second air inlet 38, and the front A first air blowing port 35 that opens toward the upper side of the vehicle at the upper end portion of the cover 16 and in the center in the vehicle width direction and an air flow path from the left and right first air introduction ports 34 are merged at a merging portion G and left and right. A first air duct 31 communicating with the one air inlet 34 and the first air outlet 35, the second air duct 32 is disposed below the merging portion G of the first air duct 31, and the merging portion G A third communication port 69 is provided between the two air ducts 32 to communicate them.

この構成によれば、第二エアダクト32及び第一エアダクト31の各導入口を左右方向(車幅方向)に並べることで、フロントカバー16の上部(スクリーン25周り)の前後厚さの増大を抑えることができる。
そして、合流部Gと第二エアダクト32との間にこれらを連通する第三連通口69を設けることで、合流部Gに第二エアダクト32内の走行風を導くことができ、合流部Gでの整流効果を高め(負圧の発生による空気抵抗を抑え)、第一空気吹き出し口35からの走行風の吹き出しを良好にしてスクリーン効果を高めることができる。
According to this configuration, by arranging the inlets of the second air duct 32 and the first air duct 31 in the left-right direction (vehicle width direction), an increase in the front-rear thickness of the upper portion of the front cover 16 (around the screen 25) is suppressed. be able to.
And by providing the 3rd communicating port 69 which connects these between the junction G and the 2nd air duct 32, the driving | running | working wind in the 2nd air duct 32 can be guide | induced to the junction G, and the junction G Rectifying effect (suppressing the air resistance due to the generation of negative pressure) can be improved, the running air blown from the first air blowing port 35 can be improved, and the screen effect can be enhanced.

また、上記自動二輪車1は、前記第三連通口69が、前記合流部Gの略中央に配置され、かつ前後方向に長い略矩形状に形成されることで、合流部Gにて左右両側から合流する走行風の流れを効率よく整流させることができる。   Further, in the motorcycle 1, the third communication port 69 is disposed in the approximate center of the merging portion G and is formed in a substantially rectangular shape that is long in the front-rear direction. The flow of the traveling wind that merges can be rectified efficiently.

また、上記自動二輪車1は、前記フロントカバー16の各リアシェル部64,65(中段壁)が前記第一エアダクト31の中間部を横断し、この各リアシェル部64,65には、前記第一エアダクト31の左右第一空気導入口34側の流路(左右下第一空気流路36)と第一空気吹き出し口35側の流路(上第一空気流路37)とを連通する左右連通口66が形成されると共に、前記第三連通口69が形成されるものである。
この構成によれば、フロントカバー16の中段壁に開口を形成して第一エアダクト31の中間部を開通させると共に、該中段壁を第二エアダクト32の上壁部としてこれに第三連通口69を形成することとなり、第一エアダクト31と第二エアダクト32との交差部分を簡素に構成できる。
In the motorcycle 1, the rear shell portions 64 and 65 (middle wall) of the front cover 16 cross the intermediate portion of the first air duct 31, and the rear shell portions 64 and 65 include the first air duct. Left and right communication ports for communicating the flow path on the left and right first air introduction port 34 side (lower left and right first air flow path 36) and the flow path on the first air outlet 35 side (upper first air flow path 37) 66 is formed, and the third communication port 69 is formed.
According to this configuration, an opening is formed in the middle step wall of the front cover 16 to open the middle portion of the first air duct 31, and the middle step wall is used as the upper wall portion of the second air duct 32 to the third communication port 69. Therefore, the intersection of the first air duct 31 and the second air duct 32 can be simply configured.

また、上記自動二輪車1は、前記第一エアダクト31とその前方に離間して設けられるフロントスクリーン26との間に形成される第三エアダクト33と、前記第二空気導入口38の上方にて車両前方に開口して走行風を導く第三空気導入口42とを備え、前記各エアダクト31,33は、それぞれ側面視で斜め下後方に向けて窪んだ湾曲部46,48を有し、これら各湾曲部46,48間には、前記第一エアダクト31の湾曲内周側と前記第三エアダクト33の湾曲外周側とを連通する第二連通口68が設けられるものである。
この構成によれば、各エアダクト31,33の湾曲部46,48では、その湾曲外周側に沿って走行風が流れることから、湾曲外周側は高圧になり易く、湾曲内周側は低圧になり易いため、第二連通口68を介して第一エアダクト31の湾曲内周側と第三エアダクト33の湾曲外周側とを連通することで、少なくとも第一エアダクト31の湾曲内周側の整流効果を高め、第一空気吹き出し口35からの走行風の吹き出しを良好にしてスクリーン効果をより一層高めることができる。
The motorcycle 1 includes a third air duct 33 formed between the first air duct 31 and a front screen 26 provided in front of the first air duct 31 and a second air inlet 38 above the second air inlet 38. The air ducts 31 and 33 each have curved portions 46 and 48 that are recessed obliquely downward and rearward in a side view, respectively. A second communication port 68 is provided between the curved portions 46 and 48 to communicate the curved inner peripheral side of the first air duct 31 and the curved outer peripheral side of the third air duct 33.
According to this configuration, in the curved portions 46 and 48 of the air ducts 31 and 33, since the traveling wind flows along the curved outer peripheral side, the curved outer peripheral side tends to be high pressure, and the curved inner peripheral side becomes low pressure. Therefore, by connecting the curved inner peripheral side of the first air duct 31 and the curved outer peripheral side of the third air duct 33 via the second communication port 68, at least the rectifying effect on the curved inner peripheral side of the first air duct 31 is achieved. The screen effect can be further enhanced by improving the blowing of the running wind from the first air outlet 35.

また、上記自動二輪車1は、前記第二空気吹き出し口39には、吹き出される走行風の方向を変更可能なルーバー39aが設けられることで、フロントカバー16後方の乗員の意思で、フロントカバー16の裏側に導く走行風量等を調整することが可能となり、乗員の選択の自由度を向上させることができる。   Further, in the motorcycle 1, the second air outlet 39 is provided with a louver 39a capable of changing the direction of the running wind to be blown out. It is possible to adjust the amount of traveling airflow guided to the rear side of the vehicle, and to improve the degree of freedom of occupant selection.
