Abstract
Description
ここで、部品としては、電磁弁や圧力センサ、電磁弁を制御する制御装置(電子制御ユニット)、機械部品等が挙げられる。
また、蓋部材の外形が周壁部の開口の中心に対して点対称形状に形成されているので、第1欠損部と第2欠損部とで面積が異なっていても、蓋部材の組付時に方向性を生じることがなく、蓋部材の組付性がよい。
つまり、エンジンルーム内には、構造物として、ブレーキ関係の装置だけではなく、駆動源(エンジンおよび/または走行モータ)、トランスミッション、ラジエータ等の冷却系、低圧バッテリなど各種の装置が搭載されるため、必然的に大きな空スペース(設置スペース)を確保することが難しくなる。しかし、本発明のようにマスタシリンダ装置に備わるハウジングの省スペース化が図られているので、狭くてレイアウトの制約の大きいエンジンルーム内において、クリアランスを確保しつつ周辺の構造物や周辺機器に近付けてハウジングを配置することができ、マスタシリンダ装置を好適に配置することができる。
つまり、マスタシリンダ装置に備わるハウジングの省スペース化が図られているので、狭くてレイアウトの制約の大きいエンジンルーム内において、クリアランスを確保しつつ周辺の構造物や周辺機器に近付けてハウジングを配置することができ、マスタシリンダ装置を好適に配置することができる。
電動モータは、図示せぬ電子制御ユニットからの信号に基づいて作動する。駆動力伝達部は、電動モータの回転動力を進退運動に変換したうえでスレーブピストンに伝達する。スレーブピストンは、電動モータの駆動力を受けてスレーブシリンダ内を摺動し、スレーブシリンダ内のブレーキ液を加圧する。
モータシリンダ装置A2で発生したブレーキ液圧は、管材Hc,Hdを介してマスタシリンダ装置A1に入力され、連絡液圧路9c,9dおよび管材Ha,Hbを介して液圧制御装置A3に入力される。リザーバには、メインリザーバ(図示略)から延びるホースが接続される。
車両用ブレーキシステムAが正常に機能する正常時には、常開型遮断弁4,5が弁閉状態となり、常閉型遮断弁6が弁開状態となる。かかる状態でブレーキペダルPを操作すると、マスタシリンダ1で発生したブレーキ液圧は、ホイールシリンダWに伝達されずにストロークシミュレータ2に伝達され、ピストン2aが変位することにより、ブレーキペダルPのストロークが許容されるとともに、擬似的な操作反力がブレーキペダルPに付与される。
図示せぬ電子制御ユニットは、モータシリンダ装置A2から出力されたブレーキ液圧(圧力センサ7で検知されたブレーキ液圧)とマスタシリンダ1から出力されたブレーキ液圧(圧力センサ8で検知されたブレーキ液圧)とを対比し、その対比結果に基づいて電動モータの回転数等を制御する。
本実施形態のマスタシリンダ装置A1は、図2(a)(b)の基体10の内部あるいは外部に前記の各種部品を組み付けるとともに、電気によって作動する電気部品(常開型遮断弁4,5、常閉型遮断弁6および圧力センサ7,8(図1参照)をハウジング20で覆うことによって形成されている。なお、ハウジング20内には、機械部品等が収納されてもよい。
リザーバユニオンポートは、円筒状を呈しており、その底面から第一シリンダ穴11aに向かって延びる孔を介して第一シリンダ穴11aと連通している。リザーバユニオンポートには、リザーバ3の下部に突設された図示しない給液口が接続され、リザーバユニオンポートの上端には、リザーバ3の容器本体が載置される。
ハウジング本体21は、図3に示すように、フランジ部22と、フランジ部22に立設された周壁部23と、周壁部23の周壁面から突設されたコネクタ部としての2つのコネクタ24,25と、を有している。
開口縁234は、蓋部材30の外形に対応した形状とされている。
蓋部材30は、2組の対向する2辺で形成される四角形(一点鎖線で図示した長方形)に内接する外形を有している。蓋部材30は、この四角形の2組の対角のうちの一方の対角を同じ大きさで欠損させてなる一対の第1欠損部32,32、および他方の対角を同じ大きさで欠損させてなる一対の第2欠損部33,33を有している。第1欠損部32,32および第2欠損部33,33は、ともに三角形状を呈している。
第1傾斜縁302,302は、隣接する直線縁301,301同士を繋いでおり、互いに平行である。第2傾斜縁303,303は、隣接する直線縁301,301同士を繋いでおり、互いに平行である。
なお、第1欠損部32(第1傾斜縁302)、第2欠損部33(第2傾斜縁303)の辺の長さは、第1欠損部32(第1傾斜縁302)の方が長くなっており、第1欠損部32は、第2欠損部33よりも面積(欠損量)が大きくなっている。
ここで、後記するようにマスタシリンダ装置A1は、図8(a)に示すように、エンジンルームER内において基体10の前側を車両の前側へ向けて搭載されるようになっており、これにより、一方の第1傾斜縁302は、基体10の前側下部に形成されるようになっている。つまり、一方の第1傾斜縁302は、エンジンルームER内において、構造物や周辺機器Mが存在し易いスペースに向けて配置されるようになっている。
なお、前側上部の第2欠損部33にネジ挿通孔27の中心が位置することが望ましく、さらに望ましくは、ネジ挿通孔27の全体が第2欠損部33に位置するとよい。
ここで、1つの第1傾斜縁302に形成されている凹部30bの数は2個であり、また、1つの第2傾斜縁303に形成されている凹部30bの数は1個である。つまり、第1欠損部32に面する周縁に設けられる凹部30bの数は、第2欠損部33に面する周縁に設けられる凹部30bの数よりも多くなっている。
なお、4つの直線縁301には、それぞれ4個の凹部30bが設けられている。
また、蓋部材30の裏面における周縁の内側には、図4(b)に示すように、周縁部に沿う溶着部34が膨出形成されている。溶着部34の内側には、周溝30eが形成されている。
4つの直線縁部231は、蓋部材30の直線縁301にそれぞれ対応しており、第1傾斜縁部232,232は、蓋部材30の第1傾斜縁302,302に対応しており、また、第2傾斜縁部233,233は、蓋部材30の第2傾斜縁303,303に対応している。
開口縁234は平らな面とされており、蓋部材30の裏面の溶着部34が当接して溶着される。なお、開口縁234の外周縁には、周リブ235が形成されている。
これにより、フランジ部22に近い側において、コイル等の比較的大径の部品も周壁部23の内側に好適に収容することが可能となっている(図7(b)参照)。また、開口21aに近い側において、周壁部23の下部が内側にオフセットされているので、周壁部23の下部周りの省スペース化を図ることができる。
そして、第1欠損部32(図4(a)参照)に近い側(上下方向下側)に設けられる一方のコネクタ25は、他方のコネクタ24よりも周壁部23からの突出量が小さくなっている。
また、コネクタ25は、図7(a)に示すように、前方から見た形状においても、コネクタ24より小さくなっている。
なお、構造物や周辺機器Mとしては、エンジンに備わる電動機やその他の構造物、例えば、ブレーキ関係の装置だけではなく、トランスミッション、ラジエータ等の冷却系、低圧バッテリなど各種の装置が挙げられる。このような構造物や周辺機器Mに対しても、ハウジング20を近付けて配置することができる。
また、第1欠損部32に形成されている凹部30bの数は、第2欠損部33,33に形成されている凹部30bの数よりも多いので、特に、第1欠損部32,32および第2欠損部33,33において反りや歪みが生じるのを好適に防止することができ、蓋部材30の密閉性を高めることができる。
