Abstract
Description
本願は、2017年5月31日に出願された日本国特願2017-108508号に基づき優先権を主張し、その内容をここに援用する。
左右フロントフォーク3の上部は、ステアリングステム4を介して、車体フレーム5の前端部のヘッドパイプ6に支持されている。ステアリングステム4のトップブリッジ上には、バータイプの操向ハンドル4aが取り付けられている。
左右メインチューブ7の下方には、自動二輪車1の原動機であるパワーユニットPUが懸架されている。パワーユニットPUは、後輪12と例えばチェーン式伝動機構を介して連係されている。
シフトスピンドル31の回動時には、シフトスピンドル31に固定されたシフトアーム31aがシフトドラム36を回動させ、リード溝のパターンに応じてシフトフォーク37を軸方向移動させて、変速ギヤ群24の内の動力伝達可能なギヤ対を切り替える(すなわち、変速段を切り替える。)。
ECU60は、シフトドラム36の回動角から変速段位を検知するドラム角度センサ(ギヤポジションセンサ)41、およびシフトスピンドル31に入力された操作トルクを検知するシフト荷重センサ(トルクセンサ)42からの検知情報、ならびにスロットル開度センサ43、車速センサ44およびエンジン回転数センサ45等からの各種の車両状態検知情報等に基づいて、クラッチアクチュエータ50を作動制御するとともに、点火装置46および燃料噴射装置47を作動制御する。ECU60には、クラッチアクチュエータ50の油圧センサ57,58からの検知情報も入力される。
油圧アクチュエータ51は、駆動源としての電気モータ52(以下、単にモータ52という。)と、モータ52により駆動されるマスターシリンダ51sと、を備えている。
モータ52は、その駆動軸52aに、伝達ギヤ52b、変換機構52cを介してマスターシリンダ51sのピストン51bが連結されている。変換機構52cは、駆動軸52a及び伝達ギヤ52bの回転運動をピストン51bのストローク運動に変換するもので、例えばボールネジ機構が用いられている。
メイン油路54は、マスターシリンダ51s側とスレーブシリンダ28側とを連通するよう形成されている。ソレノイドバルブ56は、メイン油路54を開通又は遮断する。ソレノイドバルブ56は、いわゆるノーマルオープンバルブである。
油圧センサ57,58は、ソレノイドバルブ56を挟んでマスターシリンダ51s側およびスレーブシリンダ28側の作動油の油圧をそれぞれ検出する。
自動二輪車1の停車時(アイドリング時)、ECU60で制御されるモータ52およびソレノイドバルブ56は、ともに電力供給が遮断された状態にある。すなわち、モータ52は停止状態にあり、ソレノイドバルブ56は開弁状態にある。このとき、スレーブシリンダ28側(下流側)はタッチポイント油圧TPより低い低圧状態となり、クラッチ26は非締結状態(切断状態、解放状態)となる。この状態は、図5の領域Aに相当する。
やがて、スレーブシリンダ28側(下流側)の油圧が下限保持油圧LPに達すると、クラッチ26の締結が完了し、エンジン13の駆動力が全て変速機21に伝達される。この状態は、図5の領域Cに相当する。
図5の領域Eのように、下流側の油圧が上限保持油圧HPまで上昇した場合、ソレノイドバルブ56への電力供給を低下させる等により、ソレノイドバルブ56を段階的に開弁状態として、下流側の油圧を上流側へリリーフする。
図6~図11に示すように、油圧バルブユニット53は、バルブボディ53aを備えている。バルブボディ53aは、油圧バルブユニット53の筐体をなし、その内部にメイン油路54およびバイパス油路55が形成されている。
メイン油路54は、主部54m及び立ち上がり流路54vが、ソレノイドバルブ56よりもマスターシリンダ51s側の上流側油路54aとされ、立ち上がり流路54wが、ソレノイドバルブ56よりもスレーブシリンダ28側の下流側油路54bとされている。
また、メイン油路54は、立ち上がり流路54v,54wをなるべく短くし、バンジョー部材62Aからメイン油路54を経てバンジョー部材62Bへと至る油路の長さをなるべく短くしている。これにより、油圧を迅速に伝達し、クラッチ26をレスポンス良く操作することができる。
分岐油路55j,55kは、バイパス油路55の主部55aの両端部と、メイン油路54の主部54mと、を接続するように形成されている。分岐油路55j,55kは、メイン油路54の主部54mから、それぞれメイン油路54に交差する方向に延びている。
バイパス油路55の主部55aの下方には、油圧センサ57,58が上下方向に延びて配置され、油圧センサ57,58の上端部が主部55aに接続されている。バイパス油路55の主部55aはメイン油路54よりも高い位置に配置され、このバイパス油路55の主部55aに向かって分岐油路55j,55kが斜め上方に延びている。このため、バイパス油路55の主部55aの下方に油圧センサ57,58の配置スペースを確保しやすく、油圧バルブユニット53の小型化に寄与している。
図8を併せて参照し、油圧センサ57,58は、バルブボディ53aを車体の所定の取付位置に取り付けた状態で、メイン油路54及びバイパス油路55の主部55aに対して下方に位置するよう設けられている。さらに、油圧センサ57,58は、メイン油路54よりも高い位置に配置されたバイパス油路55の主部55aの下方に位置するよう配置されている。油圧センサ57,58は、その中心軸線C1,C2を、上下方向に向けて配置されている。バイパス油路55の主部55aのバルブボディ53a外側における図11中右方への開放部分はスチールボールの圧入により閉塞されている。ワンウェイバルブ55vは主部55aの開放部分の閉塞前に該開放部分から挿入されている。
図8に示すように、アキュムレータ61は、メイン油路54の主部54mと立ち上がり流路54vとの合流部に接続されている。アキュムレータ61は、ピストン61aと、ピストン61aをメイン油路54側に向かって付勢するコイルバネ61bと、ピストン61a側とメイン油路54とを隔てるダイアフラム61cと、を有している。アキュムレータ61は、メイン油路54の油圧が上昇すると、ダイアフラム61cが押圧される。これにより、ダイアフラム61cを介してピストン61aがコイルバネ61bの弾性力に抗して押し込まれ、アキュムレータ61が油圧を蓄圧する。アキュムレータ61は、メイン油路54の油圧が低下すると、ピストン61aがコイルバネ61bの弾性力によってメイン油路54側に移動し、メイン油路54に作動油を戻して油圧を上昇させ油圧の変動を吸収する。
このようなアキュムレータ61は、油圧センサ57,58と平行に、上下方向に中心軸線C3を有するよう配置されている。
そして、メイン油路54とバイパス油路55の主部55aとを、互いに軸線C4,C5を揃えて配置したことにより、油圧バルブユニット53を小型化するとともに、作動油に混入したエアを、メイン油路54およびバイパス油路55の軸方向の一端側から容易かつ効率よく抜くことができる。また、バイパス油路55の主部55aをメイン油路54と同一高さ又はメイン油路54よりも高い位置に配置したことにより、バイパス油路55のエアを抜きやすくすることができる。
また、油圧センサ57,58とアキュムレータ61とが互いに軸線C1,C2,C3を揃えて配置されているので、この点でも油圧バルブユニット53の小型化を図ることができる。
例えば、油圧バルブユニット53の取付位置は、上記実施形態で例示したものに限らず、適宜他の場所に取り付けることも可能である。
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。
