The rear wall portion (85d) may be supported by the center frame (20) connected to the frame (94).
- the radiator exhaust structure of the saddle-mounted vehicle is equipped with an exhaust wall behind the radiator that covers the radiator and guides the exhaust air of the radiator to the exhaust port, and the exhaust wall provides a part of the exhaust air of the radiator from the radiator. Since it has an opening that allows the exhaust air to flow upward, the direction of the exhaust air from the radiator can be satisfactorily controlled by allowing a part of the exhaust air from the radiator to flow upward. The heat effect on the radiator can be suppressed. Depending on the layout of the vehicle, it is difficult to provide a large space between the radiator and the exhaust wall, and the exhaust air from the radiator stays between the radiator and the exhaust wall, and around the exhaust wall and the exhaust wall.

- the heat effect on the upper part of the vehicle can be suppressed. For example, it is possible to suppress the influence of heat on the electrical components around the steering wheel.
- the barrier is provided above the lower end of the lamp provided at the front of the vehicle. Therefore, the barrier changes the path of the exhaust air of the radiator above the lower end of the lamp. It is possible to suppress the amount of exhaust air from the radiator that flows through the air.

Abstract
Description
ラジエータを通過した排風は、排風口を介して車体の下方に流れる。
本発明の目的は、ラジエータの排風を良好にコントロールすることが可能な鞍乗り型車両のラジエータ排風構造を提供することにある。
鞍乗り型車両のラジエータ排風構造は、前輪(13)の後方に配置されたラジエータ(66)と、前記ラジエータ(66)を通過した排風を車体下方に排出する排風口(61c)とを備えるスクーター型の鞍乗り型車両のラジエータ排風構造において、前記ラジエータ(66)の後方に、前記ラジエータ(66)を覆って前記ラジエータ(66)の排風を前記排風口(61c)へ導く排風壁(85)を備え、前記排風壁(85)は、前記ラジエータ(66)の排風の一部を前記ラジエータ(66)よりも上方に向けて流すことが可能な開口部(85e)を備えることを特徴とする。
また、上記構成において、前記フロントインナカバー(53)は、上部が下部よりも前方に位置するように傾斜していても良い。
また、上記構成において、前記防壁(143b)は、車両前部に設けられる灯火器(141)の下端よりも上方に設けられていても良い。
また、上記構成において、車体フレーム(11)の前端部を構成するヘッドパイプ(18)からセンターフレーム(20)が下方に延びて前記傾斜壁(61g)の後方に位置する車幅方向に延びるクロスフレーム(94)に接続され、前記センターフレーム(20)に前記後壁部(85d)が支持されていても良い。
車両のレイアウトによっては、ラジエータと排風壁との間に大きな空間を設けることが難しく、ラジエータの排風が、ラジエータと排風壁との間に滞留し、排風壁と排風壁の周囲との隙間等から漏れ出して車体内の後部側などに侵入することがあるが、本発明では、これをラジエータの排風をコントロールすることにより抑制できる。
また、上記構成において、排風壁は、ラジエータの背面に対向する後壁部を備え、後壁部は、排風口の後縁部から上方斜め前方に延びる傾斜壁の後方に配置され、開口部は、傾斜壁よりも上方に配置されるので、ラジエータの排風を車体下方と車体上方とに分けて流すことができる。
図1は、本発明の実施形態の自動二輪車10を示す左側面図である。
自動二輪車10は、車体フレーム11の前端部にフロントフォーク12を介して前輪13が支持され、車体フレーム11の下部にパワーユニット14を介して後輪15が支持されている。
自動二輪車10は、車体フレーム11の上方に配置されたシート16に跨って乗車する鞍乗り型車両である。
ヘッドパイプ18は、車体フレーム11の前端部を構成し、車両側面視で後傾している。左右のダウンフレーム19Aは、ヘッドパイプ18の下部の左右からそれぞれ下方斜め側方に延びている。
パワーユニット14は、左右のロアフレーム19Bの後端部にリンクを介して上下スイング可能に取付けられ、前部を構成するエンジン35と、エンジン35の後部に一体的に設けられた無段変速機36とから構成される。
車体フレーム11を覆う車体カバー46は、フロントカバー51、左右一対のフロントサイドカバー52、フロントインナカバー53、フロアステップ56、左右一対のフロアサイドスカート57、センタカバー58、左右一対のボディサイドカバー59、ハンドルカバー60、アンダーカバー61を備える。
フロアステップ56は、レッグシールド54の下端部から下方及び後方に延びて運転者の足載せとされる。左右のフロアサイドスカート57は、フロアステップ56の左右縁部から下方に延びている。
左右のボディサイドカバー59は、フロアステップ56及びセンタカバー58からシート16の側縁の下方を車体後方に延びている。ハンドルカバー60は、ハンドル31の中央部を覆っている。
アンダーカバー61は、左右のフロアサイドスカート57のそれぞれの下縁の間に配置され、車体下部を下方から覆っている。
左右のダウンフレーム19Aの間にはラジエータ66が配置されている。なお、ダウンフレーム19Aは1本でも良い。
左右のダウンフレーム19Aは、それぞれ下端部に後方に屈曲する屈曲部19Cを備え、左右の屈曲部19C間には、ロア前部クロスフレーム81が渡されている。
左右のダウンフレーム19Aの間であって、ロア前部クロスフレーム81の上方には、ラジエータ66が、鉛直方向に対して後傾するように配置されている。
ラジエータ66を上方、下方、左方、右方及び後方を囲むように、ラジエータ66を通過した排風の方向を規制する排風壁としての排風規制部材85が配置されている。
ラジエータ66の下方のロア前部クロスフレーム81には、アンダーカバー61の前部が係合により固定されている。
排風規制部材85は、上壁部85a、下壁部85b、左右の側壁部85c及び後壁部85dを備え、これらの上壁部85a、下壁部85b、左右の側壁部85c及び後壁部85dによってラジエータ66(図2参照)を覆っている。
アンダーカバー61は、前部に上下に貫通する排風口としての下開口部61cを備える。
側壁61f,61zは、前壁61eよりも上方まで延びている。傾斜後壁61gは、排風規制部材85の一側(右側)の側壁部85cの後縁部が前後に通されるスリット(不図示)を備える。
排風規制部材85の後壁部85dは、アンダーカバー61の傾斜後壁61gの後方に配置され、図4の説明で詳述する開口部としての後開口部85eは、傾斜後壁61gよりも上方に配置されている。
左右のロアフレーム19Bは、上方に凸となるように屈曲するクロスフレームとしてのロア後部クロスフレーム94で接続されている。ロア後部クロスフレーム94は、車幅方向に延び、ロア後部クロスフレーム94の車幅方向中央の最上部94aには、センターフレーム20の下端部が接続されている。ラジエータ66と、排風規制部材85の大部分とは、センターフレーム20の前方に配置されている。
後開口部85eは、傾斜後壁61g(図3参照)より上方に位置し、ラジエータ66の排風の一部をラジエータ66の後方及びラジエータ66よりも上方に向けて流すことが可能である。
上固定部85fの左側の上後壁部85hは、下縁部に、ラジエータ66の吸水口(不図示)が配置される切欠き部85xを備える。
排風規制部材85の上壁部85aは、左右一対の左上壁部85m及び右上壁部85nからなり、左上壁部85m及び右上壁部85nのそれぞれの内側縁部同士が係合される。左上壁部85m及び右上壁部85nは、それぞれの内側縁部に半円状の切欠き部85pが形成され、左右の切欠き部85pによって出来る穴部85qにセンターフレーム20(図4参照)が通される。また、右上壁部85nは、ラジエータ66(図2参照)の注水口(不図示)が通される貫通穴85rを備える。
左右の側壁部85c及び左右の外側延長部85sは、それぞれ縦長のスリット85wが開けられている。スリット85wは、ラジエータ66の両側面に設けられた板状の被取付部(不図示)を通す部分であり、側壁部85c及び外側延長部85sのそれぞれのスリット85wは、車幅方向で重なっている。スリット85wに被取付部が挿入されることで、排風規制部材85を保持することができ、排風規制部材85の振れを抑制できる。
後壁部85dは、下縁部に切欠き部85vが形成され、切欠き部85vに複数のラジエータ配管82が通される。
ラジエータ66の前方にはルーバー111が配置される。ルーバー111は、上下方向に互いに隔てて配置された複数の羽板111aを備え、ラジエータ66に取り入れられる空気の流れの方向を規制する。ここでは、空気の流れを後方斜め下方向に向ける。
フロアステップ56の下方且つアンダーカバー61の上方で、ロア後部クロスフレーム94の後方には電装部品116が配置されている。
傾斜後壁61gは、ロア後部クロスフレーム94の直前を上下に延びる傾斜壁上部61qと、ロア後部クロスフレーム94の下方を後方斜め下方に延びる傾斜壁下部61rと、ロア後部クロスフレーム94の前方で屈曲して傾斜壁上部61q及び傾斜壁下部61rのそれぞれを接続する傾斜壁屈曲部61sとからなる。傾斜壁上部61qの上端61tは、ファンモータ114の後方に位置する。
排風路120は、ロア後部クロスフレーム94及び傾斜後壁61g(詳しくは、傾斜壁下部61r)の下方に配置されている。
排風規制部材85の後壁部85dの下部は、アンダーカバー61の傾斜後壁61g(詳しくは、傾斜壁上部61q)と、センターフレーム20の下部及びロア後部クロスフレーム94との間に配置されている。排風規制部材85の後方にセンターフレーム20が位置するため、排風規制部材85の後方へのずれを防止できる。
車両前部のヘッドパイプ18の周囲には、灯火器としてのヘッドライト141、排風抑制部材143等が配置されている。
排風抑制部材143は、上下方向に延びる壁部143aを備え、壁部143aは、フロントインナカバー53の前面53aに沿って配置されている。壁部143aは、その前面から前方に突出する防壁としての前方延出壁部143bを一体に備える。
なお、前方延出壁部143bは、フロントインナカバー53の前面53aに一体成型されていても良い。
図中に示した符号144は、前方延出壁部143bの下端を通る水平線であり、前方延出壁部143bは、ヘッドライト141の下端141aよりも上方に配置されている。
そして、上昇したラジエータ66の排風は、排風抑制部材143の前方延出壁部143bによって上昇が妨げられるため、矢印Fで示すように、前方延出壁部143bを迂回しながら上昇する。
また、前方延出壁部143bは、ヘッドライト141の下端141aよりも上方に配置されているため、前方延出壁部143bを迂回した排風の一部が車両前方に向かって上昇しても、ヘッドライト141に直接向かうことを防止し、ヘッドライト141への熱影響を抑制することができる。
この構成によれば、ラジエータ66の排風の一部を上方に向けて流すことで、ラジエータ66の排風の方向を良好にコントロールすることができ、電装品等への熱影響を抑制できる。
この構成によれば、後開口部85eから排出されるラジエータ66の排風をフロントインナカバー53に沿って上方に流すことができ、車両前部上部側に配置される電装品等への熱影響を抑制できる。
この構成によれば、より確実にラジエータ66の排風をフロントインナカバー53に沿って上方に流すことができ、車両前部上部側に配置される電装品等への熱影響を抑制できる。
この構成によれば、ラジエータ66の排風の上昇を遅らせることができ、ラジエータ66の排風が上方のハンドル31(図1参照)周りに到達するまでにラジエータ66の排風の温度を下げることができる。これにより、ハンドル31周りの電装品等への熱影響を抑制できる。
この構成によれば、前方延出壁部143bによりヘッドライト141の下端141aよりも上方でラジエータ66の排風の進路を変えて、ヘッドライト141に流れるラジエータ66の排風の量を抑えることができる。
この構成によれば、ラジエータ66の排風を車体下方と車体上方とに分けて流すことができる。これにより、ラジエータ66の排風の方向を良好にコントロールすることができる。
この構成によれば、車体フレーム11の一部を利用して排風規制部材85を支持することができ、特別に排風規制部材85の支持部を設ける必要がない。また、センターフレーム20は、傾斜後壁61gの後方に配置されるため、センターフレーム20によって車体下方へ流れるラジエータ66の排風の流れを妨げることがなく、車体下方にラジエータ66の排風をスムーズに流すことができる。
本発明は、自動二輪車10に適用する場合に限らず、自動二輪車10以外も含む鞍乗り型車両に適用可能である。
