Abstract
Description
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共に、擬似的な操作反力がブレーキペダルPに付与される。
本実施形態の初動装置A1は、前記の各種部品を図2の基体10の内部あるいは外部に組み付けると共に、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及び圧力センサ7、8)をハウジング20で覆うことによって形成されている。
図3及び図4に示すように、配管接続部15は、管取付座となる部位であり、基体10の前面部30に形成されている。平坦面からなる基体10の前面部30には、二つの出力ポート(複数のポート)15a、15bと、二つの入力ポート(複数のポート)15c、15dとが略ハの字状に配置されている。また、二つの出力ポート15a、15b間の離間距離は、二つの入力ポート15c、15d間の離間距離よりも小さく設定されている。出力ポート15a、15bには、液圧制御装置A3に至る管材Ha、Hb(図1参照)が接続され、入力ポート15c、15dには、モータシリンダ装置A2に至る管材Hc、Hd(図1参照)が接続される。
