Abstract
Description
図4~図6に示すように(適宜、図1~図3も参照)、キャリア3は、一対のスライドピン15、15が挿通される一対のピン挿嵌部10、10と、一対のピン挿嵌部10、10に一体的に連結され、インナ及びアウタパッド4、5をそれぞれ独立して支持するインナ側及びアウタ側支持部11、12とを備えている。一対のピン挿嵌部10、10は、ディスク回転方向に沿って間隔を置いて配置され、共にディスク軸方向に沿ってそれぞれ延びている。各ピン挿嵌部10は、内部にスライドピン15が挿通されるピン穴14を有する有底円筒状に形成される。各ピン挿嵌部10はそのピン穴14の開口側がインナ側を向き、その底部側がアウタ側を向く。各ピン挿嵌部10のインナ側端部のピン穴14の周りには、円筒状のピン穴ボス部16が形成される。ピン穴ボス部16の外径は、ピン挿嵌合部10の外径よりも大径である。各ピン挿嵌部10のアウタ側にアウタ側支持部12が一体的に連結される。各ピン挿嵌部10の、アウタ側支持部12からディスク軸方向に沿ってインナ側に間隔を置いてインナ側支持部11が連結される。
なお、インナ側支持部11が、アウタ側支持部12よりも、そのディスク軸方向に沿う全体的な厚みが厚く形成される。
これに対して、キャリア3に電動モータ57との干渉を避ける逃げ部を形成することが考えられる。しかし、該逃げ部を後工程の機械加工で形成すると、コスト高となる。また、鋳型構造に中子や入子等を採用してアンダーカット処理により逃げ部を一体成形する場合でも、鋳型構造が複雑化して、コスト高となる。
キャリパ6は、キャリパ本体55と、ピストンユニット56と、キャリパ本体55と並ぶように配置される電動モータ57と、ピストンユニット56及び電動モータ57を収容するハウジング58とが一体的に構成される。
キャリパ本体55には、ディスクロータ2の一側に対向して開口する円筒状のシリンダ部60と、シリンダ部60からディスクロータ2を跨いで反対側へ延びる爪部61と、シリンダ部60から外方に延びる一対のキャリパ腕部62、62が一体的に形成される。一対のキャリパ腕部62、62にはそれぞれスライドピン15、15が各固定ナット65、65により固定される。各スライドピン15、15が、キャリア3の各ピン挿嵌部10のピン穴14に軸方向に摺動自在に挿通される。各スライドピン15、15の一端部とキャリア3のピン挿嵌部10、10との間には、スライドピン15、15を覆う伸縮自在な蛇腹部を有するゴム製のピンブーツ66、66が設けられている。シリンダ部60には、ピストンユニット56のピストン70が摺動可能に嵌合される案内ボア68が形成されている。
まず、ブレーキペダル(図示略)の操作による通常の液圧ブレーキとしてのディスクブレーキ1の制動時における作用を説明する。
運転者によりブレーキペダルが踏み込まれると、ブレーキペダルの踏力に応じた液圧がマスタシリンダから液圧回路(共に図示略)を経てキャリパ本体55のシリンダ部60内の液圧室に供給される。これにより、ピストン70がピストンシール(図示略)を弾性変形させながら非制動時の原位置から前進(図11の左方向に移動)してインナパッド4をディスクロータ2に押し付ける。そして、キャリパ本体55は、ピストン70の押圧力の反力によりキャリア3に対して図11における右方向に移動して、爪部61に取り付けられたアウタパッド5をディスクロータ2に押し付ける。この結果、ディスクロータ2が一対のインナ及びアウタパッド4、5により挟みつけられて摩擦力が発生し、ひいては、車両の制動力が発生する。
これにより、キャリア3のインナ側支持部11(一方のインナ側腕部18)に設けた、電動モータ57との干渉を避ける凹部28の部位にアンダーカット部が成形されないので、該凹部28を、アンダーカット処理構造を含まない一対の鋳型50、51によって一体成形することが可能になる。
第1の態様としては、ディスクブレーキは、ロータを挟んで該ロータの軸方向における該ロータの両側に配置される一対のパッドと、前記一対のパッドを支持するキャリアと、を備え、該キャリアは、車両の非回転部に取り付けられるビーム部と、該ビーム部の両端部から前記ロータの径方向に延びる一対の腕部と、該一対の腕部から前記ロータを跨いで延びる一対のピン挿嵌部と、該各ピン挿嵌部の端部にそれぞれ形成され、前記ロータ軸方向に沿って設けられた一対のピン穴と、該ピン穴の周囲に設けられるピン穴ボス部と、を備え、前記一対の腕部のうちの一方において、ディスクと反対側の面に、前記一対の腕部のうちの他方に向かって開口する凹部が形成されている。
第2の態様としては、第1の態様において、前記凹部は、前記一対の腕部のうちの一方において、前記一対のピン穴の中心を結んだ線分に対して垂直となる、該一方側のピン穴ボス部の他方側端部と接する線よりも、該接する線に平行かつ該一方側のピン穴の中心を通る線側へ向かう方向に、鋳抜かれて形成される。
第3の態様としては、第1の態様または第2の態様のいずれかにおいて、前記一対の腕部に対して、前記キャリアの、ロータ軸方向に沿う中心とは反対側に配置される他方側の一対の腕部を備え、前記一対の腕部と、前記他方側の一対の腕部との距離は、前記ビーム部から離れるに従い大きくなっている。
第4の態様としては、第2の態様において、第1の態様乃至第3の態様のいずれかにおいて、前記キャリアは、アンダーカット処理構造を含まない一対の鋳型で成形される。
第5の態様としては、第2の態様において、第1の態様乃至第4の態様のいずれかにおいて、前記凹部は、前記一方の腕部の、他方の腕部との対向面からインナ側の内面に至る範囲に形成される。
第6の態様としては、ロータを挟んで該ロータ軸方向両側に配置される一対のパッドと、前記一対のパッドを支持するキャリアと、を備え、該キャリアは、 車両の非回転部に取り付けられるビーム部と、該ビーム部の両端部から前記ロータの径方向に延びて形成される一対の腕部と、該一対の腕部から前記ロータを跨いで延びるピン挿嵌部と、該各ピン挿嵌部の端部にそれぞれ形成され、ロータ軸方向に沿って穿設される一対のピン穴と、該ピン穴の周囲に設けられるピン穴ボス部と、前記一対の腕部のうちの一方において、前記一対のピン穴の中心を結んだ線分に対して垂直となる、該一方側のピン穴ボス部の他方側端部と接する線よりも、該接する線に平行かつ該一方側のピン穴の中心を通る線側へ向かう方向に凹部を備えるディスクブレーキの製造方法であって、前記キャリアは、前記一対のピン穴の中心を結んだ線分に対して垂直方向に延びる線分が型開閉方向に対して傾斜するように、内部にキャリア相当の製品キャビティを形成した一対の鋳型により成形される。
