Abstract
Description
ここで、クロスパイプは、後輪が支持されるリヤフォークの前端部を揺動自在に支持する左右一対のピボットフレームを連結するものである。
しかし、全ての鞍乗型車両において、燃料タンクやエンジンの吸気系の近傍に配置したキャニスタの近傍にクロスパイプが存在するとは限らず、クロスパイプそのものを備えない場合もあり得る。すると、キャニスタに導入する清浄な大気を確保するために、大気導入管を長くせざるを得ない場合があり、圧力損失の増大、大気導入管の取り回しに手間がかかる等の問題が生じる。また、キャニスタ近傍に専用のチャンバを設けると、部品点数及び組み付け工数が増加してしまう。
上記第三の態様によれば、チャンバ部の上方に向けて開口する開口部に、エアクリーナケースの底部が対向することで、外部から埃や水等の異物がチャンバ部内に侵入するのを防ぐことができる。
上記第四の態様によれば、サブパイプが配置されることで、側壁部の上端部とエアクリーナケースとの間から外部から埃や水等の異物がチャンバ部内に侵入するのを防ぐことができる。
上記第五の態様によれば、リヤフェンダの前部が車体フレームに固定される。したがって、リヤフェンダの前側においてリヤフェンダを車体フレームに締結するための構造が省略できる。その結果、リヤフェンダの取付作業を容易かつ効率的に行うことが可能となる。
上記第六の態様によれば、チャンバ部を有したリヤフェンダと、エアクリーナケースとを、同一の部品であるサブパイプに固定することができる。したがって、チャンバ部とエアクリーナケースとの位置精度を容易に確保することができる。
上記第七の態様によれば、キャニスタを、クランクケースの上側かつシリンダの後方に配置し、チャンバ部を後輪とエンジンの間に配置することで、キャニスタと各部品を接続するパージ管、チャージ管、大気導入管の長さを短くすることができる。
上記第八の態様によれば、サイドスタンドを接地させて鞍乗型車両をサイドスタンド側に傾斜した状態で駐車した場合、チャンバ部において水抜き孔が傾斜方向下方に位置する。したがって、駐車時にチャンバ部から水が抜けやすい。さらに、大気導入管は、チャンバ部において傾斜方向上方に位置するので、チャンバ部内に水が侵入してしまった場合にも、キャニスタに水を吸い込む可能性を抑えることができる。
図1に示すように、本発明の実施形態に係る鞍乗型車両としての自動二輪車1の車体フレーム2は、ヘッドパイプ3と、メインフレーム4と、リヤフレーム5L,5Rと、ダウンフレーム6と、ピボットブラケット7と、サブパイプ8L,8Rと、を備えている。
メインスタンド17Mは、車体フレーム2を直立状態で支持するもので、車体幅方向に間隔を空けた二本一対のスタンド脚17L,17Rを有している。
サイドスタンド17Sは、車体幅方向左側に設けられている。サイドスタンド17Sの先端部を接地させると、自動二輪車1は、車体幅方向左方に傾斜した状態で支持される。
さらに、リヤフレーム5L,5Rには、シート18の下方部分においてリヤフレーム5L,5Rを覆うテールカバー19が支持されている。
自動二輪車1の吸気系は、エアクリーナケース32、吸気ダクト33、燃料供給装置34及びインレットパイプ35で構成される。なお、吸気系では、エアクリーナケース32側からシリンダ27側に向けて吸気が流れる。以下では、吸気の流れにおいて、エアクリーナケース32側を上流側、シリンダ27側を下流側と呼ぶ場合がある。
本実施形態では燃料供給装置34がキャブレタであるが、スロットル弁を有するスロットルボディとインジェクタとで燃料供給装置を構成してもよい。この場合に、インジェクタは、スロットルボディと一体であっても、スロットルボディと別体でこれと離間して配置されるものであってもよい。また、本実施形態では、インレットパイプ35が燃料供給装置34と直接接続されるものであるが、インシュレータを介して接続するものでもよい。
図3~図6に示すように、キャニスタ50は、ゴム系材料等の弾性部材からなる略筒状の保持部材51に挿入されている。保持部材51には、キャニスタ50の径方向外周側に突出するステー挿入部51aが一対形成されている。これらステー挿入部51aに、ピボットブラケット7(図1参照)に固定された不図示の支持ステーが挿入されることで、キャニスタ50は、ピボットブラケット7に取り付けられている。
キャニスタ50のドレインポート50dには、ドレイン管55が接続されている。このドレイン管55は、キャニスタ50から下方に引き出され、ドレイン管55の他端を下方に向けて開放している。
キャニスタ50の大気開放ポート50aには、大気導入管56が接続されている。この大気導入管56の他端56bは、後述するチャンバ部60に接続されている。
図2~図8に示すように、リヤフェンダ61の前端部には、チャンバ部60が形成されている。これにより、チャンバ部60は、エンジン25と後輪WRとの間に配置されている。このチャンバ部60は、リヤフェンダ61において後輪WRに面する泥除け面61fから該後輪WRの外周側に突出するよう設けられている。
図6、図8に示すように、底面部62には、チャンバ部60内に侵入した水等を排出する水抜き孔66が貫通形成されている。
ここで、底面部62は前下がりに傾斜しており、この底面部62において、水抜き孔66は、サイドスタンド17Sが設けられた車体幅方向一方側(左方)の前側に形成されている。また、チャンバ部60において、サイドスタンド17Sが設けられた側とは反対側の車体幅方向他方側(右方)の後側に設けられた接続口64jに、大気導入管56が接続されている。
そして、チャンバ部60において、車体幅方向両側の側方壁部64には、車体幅方向外側に突出する2つの係合爪(係合部)67A,67Bが形成されている。図7、図8に示すように、一方の係合爪67Aは、側方壁部64の上端部から、側方壁部64に直交して車体幅方向外方に向けて突出して形成されている。他方の係合爪67Bは、係合爪67Aよりも車体前方位置に配置されている。係合爪67Bは、側方壁部64の上端部から上方に延出する延出部67cと、延出部67cの上端から車体幅方向外方に向けて突出する爪部67dとから形成されている。図3、図4に示すように、係合爪67Aと係合爪67Bの爪部67dとは、サブパイプ8L,8Rを挟んで一方の側(下面側)及び他方の側(上面側)のそれぞれに沿うよう配置されている。そして、係合爪67Aと係合爪67Bの爪部67dとの間にサブパイプ8L,8Rを嵌め込むことによって、リヤフェンダ61の前端部が、サブパイプ8L,8Rに係合される。すなわち、係合爪67A,67Bが、リヤフェンダ61の前側における係合部として機能する。
ここで、サブパイプ8L,8Rの上面側とエアクリーナケース32の底部32bとの間には、隙間C2が形成されている。さらに、サブパイプ8L,8Rの下面側と側方壁部64の上端部との間にも、隙間C3が形成されている。これら隙間C2,C3を通して、チャンバ部60内に外気を導入できるようになっている。
また、キャニスタ50は、車両制御装置の制御に基づいてCPCV53が開いたときに、キャニスタ50に貯留された蒸発燃料を、吸気系に供給する。これには、シリンダ27内でピストンが動作することによって生じる吸気負圧が利用され、チャンバ部60から大気導入管56を経て導入した大気と、キャニスタ50に貯留された蒸発燃料との混合気が、パージ管52に引き込まれる。パージ管52に引き込まれた蒸発燃料を含む混合気は、自動二輪車1の吸気系のインレットパイプ35からシリンダ27内に引き込まれ、エンジン25で燃焼される。
このようにして、チャンバ部60は、リヤフェンダ61の泥除け面61fの外周側に配置されているので、水や埃の入りにくい空間を確保することができる。このチャンバ部60に大気導入管56を接続することで、大気導入管56を長くするのを回避しつつ、清浄な空気をキャニスタ50に導入することが可能となる。また、リヤフェンダ61にチャンバ部60を一体形成することで、キャニスタ50近傍に専用のチャンバを設ける場合と比べて、部品点数及び組み付け工数の増加を抑えることができる。
このように、チャンバ部60を、上方に開口した形状とすることで、リヤフェンダ61とともにチャンバ部60を樹脂成形する際に脱型がしやすく、リヤフェンダ61の製造を容易に行うことができる。
チャンバ部60の上方に向けて開口する開口部65に、エアクリーナケース32の底部32bが対向することで、外部から埃や水等の異物がチャンバ部60内に侵入するのを防ぐことができる。
サブパイプ8L,8Rが配置されることで、側方壁部64の上端部64uとエアクリーナケース32との間から外部から埃や水等の異物がチャンバ部60内に侵入するのを防ぐことができる。
これにより、リヤフェンダ61の前部が車体フレーム2に固定される。したがって、リヤフェンダ61の前側における車体フレーム2に締結するための構造が省略できる。その結果、リヤフェンダ61の取付作業を容易かつ効率的に行うことが可能となる。
これにより、チャンバ部60を有したリヤフェンダ61と、エアクリーナケース32とを、同一の部品であるサブパイプ8L,8Rに固定することができる。したがって、チャンバ部60とエアクリーナケース32との位置精度を容易に確保することができる。
また、チャンバ部60の開口部65に対向して配置するエンジン補機部品として、例えばバッテリトレイ等、他の部品を採用することも可能であるが、エアクリーナケース32は、他の部品よりも形状の自由度が高い。したがって、エアクリーナケース32の底部32bを、チャンバ部60と形状を合わせやすい。
このように、キャニスタ50を、クランクケース26の上側かつシリンダ27よりも後方に配置し、チャンバ部60を後輪WRとエンジン25の間に配置することで、キャニスタ50と各部品を接続するパージ管52、チャージ管54、大気導入管56の長さを短くすることができる。
これにより、サイドスタンド17Sを接地させて自動二輪車1をサイドスタンド17S側に傾斜した状態で駐車した場合、チャンバ部60において水抜き孔66が傾斜方向下方に位置する。したがって、駐車時に水が抜けやすい。さらに、大気導入管56は、チャンバ部60において傾斜方向上方に位置するので、チャンバ部60内に水が侵入してしまった場合にも、キャニスタ50に水を吸い込む可能性を抑えることができる。
例えば、上記実施形態では、運転者が車体を跨いで乗車する車両全般が含まれ、自動二輪車(原動機付自転車及びスクータ型車両を含む)のみならず、三輪(前一輪かつ後二輪の他に、前二輪かつ後一輪の車両も含む)又は四輪の車両も含まれる。
また、エンジンは単気筒エンジンに限らず、多気筒エンジンに適用してもよい。
そして、上記実施形態における構成は本発明の一例であり、当該発明の要旨を逸脱しない範囲で種々の変更が可能である。
