Abstract
Description
本発明は、上述した事情に鑑みてなされたものであり、吸気口が目立ち難く走行風を取り入れ易い鞍乗り型車両の吸気構造を提供することを目的とする。
鞍乗り型車両の吸気構造は、フロントフォークの間に吸気ダクトを配する鞍乗り型車両の吸気構造であって、前記吸気ダクトは、前方に開口する吸気口を備え、前記フロントフォークの前方には第1の灯火器が配され、前記第1の灯火器は、前記吸気口の外周に沿って延在していることを特徴とする。
この構成によれば、第2の灯火器の凸型形状により走行風を車幅方向に分かれさせて、第2の灯火器の車幅方向の吸気口に取り込ませ易くできる。
図1は、本発明の実施の形態に係る鞍乗り型車両10の側面図である。
鞍乗り型車両10は、車体フレーム11と、車体フレーム11に支持されるパワーユニット12と、前輪13を操舵自在に支持するフロントフォーク14と、後輪15を支持するスイングアーム16と、乗員用のシート17とを備える車両である。
鞍乗り型車両10は、乗員がシート17に跨るようにして着座する車両である。シート17は、車体フレーム11の後部の上方に設けられる。
シート17は、リアフレーム20に支持される。
後輪15は、スイングアーム16の後端部に設けられる車軸15aに支持される。
パワーユニット12は、内燃機関である。パワーユニット12は、クランクケース23と、往復運動するピストンを収容するシリンダー部24とを備える。シリンダー部24の排気ポートには、排気装置25が接続される。
パワーユニット12の出力は、パワーユニット12と後輪15とを接続する駆動力伝達部材によって後輪15に伝達される。
フロントフェンダー26は、フロントフォーク14に取り付けられる。リアフェンダー27及びステップ28は、シート17よりも下方に設けられる。燃料タンク29は、車体フレーム11に支持される。
鞍乗り型車両10は、ヘッドライト40とメーターディスプレイ(メーター装置)50とを備える。ヘッドライト40はヘッドライトステー46を介してフロントフォーク14に支持されている。メーターディスプレイ50はメーターステー56を介してフロントフォーク14に支持されている。
ステアリングシャフト31と、トップブリッジ32と、ボトムブリッジ33と、左右一対のフォークチューブ34とにより、本実施形態のフロントフォーク14が構成される。
本実施形態のヘッドライトステー46は、金属ステーである。ヘッドライトステー46は、ブリッジステー部32Cから下方に延びるセンター部(ステー部分)46Aを有する。センター部46Aは、断面U字形状に形成されている。センター部46Aは、先細っており、正面視では、下端側(先端側)になるほど幅狭になっている。センター部46Aは、側面視では、上方に凸に湾曲して下方に延びている(図2参照)。
固定部46A1は、ブリッジステー部32Cの左右に配置され、それぞれの締結部材71が挿通されて締結部32Fに支持される。センター部46Aの下部には、前方から後方に切り欠かれた形状の灯火器支持部46A3(図3参照)が形成されている。
本実施形態では、サイド部46B、46Cは、センター部46Aの下端に接続される。換言すれば、本実施形態のサイド部46B、46Cは、左側のサイド部46Bと右側のサイド部46Cとの全体で上方が開放された略U字形状(あるいは略C字形状)を形成し、略U字形状(あるいは略C字形状)の開放端となる上端がセンター部46Aの上部後部に左右方向外側から接続されている。
すなわち、正面視において、吸気口61は、左右方向外縁61A1、61B1と、上縁61A2、61B2と、下縁61A3、61B3とにより、少なくとも一部の開口形状が形成されている。
本実施形態のDRL41では、正面視で、ハウジング41Aが、逆U字の帯状に延びる発光部41Cに比べて、各部分で幅広に形成されている。ハウジング41Aは、後方にいく程、幅広に構成されている。ハウジング41Aは、吸気口61側では、後方に進むに連れて吸気口61側に傾斜した壁面を有する。これにより、前方からの走行風がハウジング41Aに案内されて、左右の吸気口61A、61Bに取り込まれ易くなっている。
吸気口61の外周の大部分に目立ち易いDRL41が配されるため、吸気口61を前方に配置しながら、吸気口61を相対的に目立ち難くすることができる。よって、吸気口61が目立ち易い場合に比べて、鞍乗り型車両10の意匠性が向上している。
また、センター部46Aには、DRL41が配置されておらず、DRL41の支持するための切り欠きや締結孔などを設ける必要がなく、センター部46Aの高強度化に寄与することができる。
DRL41とビームライト42とにより、本実施形態のヘッドライト40が構成される。ヘッドライト40は、フロントフォーク14のフォークチューブ34の前方に配置される。
ヘッドライトステー46のサイド部46B、46Cは、断面では湾曲板状に形成されており、車幅方向外側に進むに連れて下方に湾曲している。左右のサイド部46B、46Cには、逆U字湾曲形状の後部ステー(第二のヘッドライトステー)47が支持される。後部ステー47は、サイド部46B、46Cに固定される。後部ステー47は、左右方向に延びる締結部材73でサイド部46B、46Cに固定される(図2、図3など参照)。
これに対して、本実施形態では、ヘッドライト40の前面に吸気口61が形成され、ヘッドライト40およびヘッドライトステー46により、ヘッドライトダクト60が形成されており、効率よく、車体フレーム11側の後部ダクト66に走行風を導くことができる。
上記実施の形態では、車幅方向一対の発光部41D、41Eが、正面視において、吸気口61の下方に配される部分を有したが、吸気口61の下方に代えて吸気口61の上方に配されても良い。
