Description

【０００１】
【産業上の利用分野】
本発明は主として、自動車用のエンジン冷却水冷却用ラジエータの樹脂製タンクであって、内部にオイルクーラが挿入され、タンク外面からそのオイルクーラにオイルパイプが接続されるものに関する。
【０００２】
【従来の技術】
ラジエータの出口側のタンク内には、自動変速機用オイルを冷却するオイルクーラが内装されている。従来のオイルクーラの取付構造は、図９に示すものであった。これは、オイルクーラ２の両端部にオイル出口用の一対のボス部が突設され、それに整合してタンク本体１の側壁に一対の貫通孔が形成されていた。そして、そのボス部を貫通孔に液密に挿入し、そこに夫々オイルパイプ５，９の端部を接続していた。そして、一方のオイルパイプ５はタンク本体１の外面に沿って曲折して、他方のオイルパイプ９の近傍に導かれ、そのオイルパイプ５の適宜位置が取付金具22によってタンク本体１に締結固定されていた。このように両オイルパイプ５，９の開口端を近接させるのは、図示しない一対のオイルホースを近接して配置し、それらと両オイルパイプ５，９とを合理的に接続する必要性からである。
【０００３】
また、オイルパイプ５を取付金具22によってタンク本体１に固定する代わりに、図１０の如く、タンク本体１に側面Ｕ字状の把持用突部23を一体に形成したものも提案されている。これは、合成樹脂製のタンク本体１と一体の材料からなり、少なくと先端部が弾性的に拡縮できるものであって、その出入口部が中心直径よりも小さく形成されている。
【０００４】
【発明が解決しようとする課題】
図９に示すように一方のオイルパイプ５をタンク本体１の外面に沿って曲折し、その適宜位置を取付金具22により、タンク本体１の外面に締結固定する場合、その取付工数が多くなると共に部品点数が多くなり、その分だけラジエータの製造コストが上昇する。
また図１０の如く、把持用突部23をタンク本体１と一体成形し、その先端の出入口部を中心直径より小に形成したものにおいては、オイルパイプ５の装着時に把持用突部23の先端部を破損し易い欠点がある。また、把持用突部23の成形が面倒である。即ち、先端開口部が縮小しているため、タンク本体１の長手方向そって長く出入する中子用の棒材を金型に組み込む必要があり、金型の製造コストが高くなる欠点がある。
しかも、その移動軌跡上には他の突出物を成形することができない。
そこで本発明は、それらの欠点を取除いたオイルクーラ内蔵ラジエータの樹脂製タンクを提供することを課題とする。
【０００５】
【課題を解決するための手段】
請求項１に記載の本発明は、一方が開口された細長いに箱状の樹脂製のタンク本体１に、細長いオイルクーラ２が内蔵されると共に、
そのオイルクーラ２のオイル出入口に整合して、タンク本体１の側壁に長手方向に離間し一対のオイルパイプの接続孔３，４が貫通し、
その一方の接続孔３に一端を接続したオイルパイプ５が、他方の接続孔４に向けてその側壁外面に沿って案内されたオイルクーラ内蔵ラジエータの樹脂製タンクにおいて、
前記他方の接続孔４の近傍で、前記長手方向に僅かに離間して、オイルパイプ５の外面把持用の一対のフック状の第１係止部６および第２係止部７が前記側壁外面に一体に突設成形され、
第１係止部６はそのフック状の開口側がタンク本体１の底面側に向き、第２係止部７のフック状の開口側はそれと逆向きに配置され、
たことを特徴とするオイルクーラ内蔵ラジエータの樹脂製タンクである。

前記第１係止部６および第２係止部７と、前記一方の接続孔３との間に、前記オイルパイプ５の外周把持用の第３係止部８が前記側壁外面に一体に突設成形され、
その第３係止部８は、その把持面が略断面半円状でその開口側が側壁外面の外向き方向と同一に向けられたオイルクーラ内蔵ラジエータの樹脂製タンクである。
請求項３に記載の本発明は、請求項２において、
第３係止部８の略断面半円状の把持面の上縁側または下縁側が前記側壁外面に直交する外側方向に延在されたオイルクーラ内蔵ラジエータの樹脂製タンクである。
【０００７】
【発明の実施の形態】
次に、図面に基づいて本発明の実施の形態につき説明する。

【０００９】
このようなタンク本体１の外面には図１に示す如く、一対の第１係止部６，第２係止部７が近接して樹脂材で一体に突設形成されると共に、それと接続孔３との中間部に第３係止部８が同様に樹脂材で一体に突設形成されている。第１係止部６，第２係止部７は、図５に示す如く接続孔４の近傍にあって、タンク本体１の長手方向に僅かに離間して、夫々図１の如く、フック状に形成され、第１係止部６はそのフック状の開口側がタンク本体１の底面側に向き、第２係止部７はそれとは逆向きに配置されている。そして、第３係止部８は、第１係止部６と接続孔３との中間位置にあって、横断面の内周がほぼ半円形であって、その内周面がタンク本体１の外向きに形成されている。そして、内周面の上縁部は、僅かに外方へ延在されている。なお、第１係止部６，第２係止部７並びに第３係止部８の円弧状把持面の内周直径は、ほぼオイルパイプ５の外周直径に整合する。
【００１０】
また、第１係止部６，第２係止部７の先端部対向側面は、図１の如く互いに逆向きに傾斜した傾斜面24に形成されている。このようにしてなる第１係止部６，第２係止部７，第３係止部８にオイルパイプ５を把持させるには、図２〜図４の如く装着する。このときタンク本体１内には、オイルクーラ２が挿入され、その両端部に突設された短い筒状のボス部が接続孔３に挿入される。そして、その両端部が一例として図８の如くナット13によって締結固定されている。次いで、図２の如く、両端部が僅かに曲折形成され、その一方の端部に中空ボルト11が嵌着されたオイルパイプ５の他端部を第１係止部６と第２係止部７との間に挿入する。次いで、図３および図４の如くオイルパイプ５全体を左回転して、夫々の係止部のＵ字溝内に嵌入する。そして、中空ボルト11をオイルクーラ２のボス部に整合させ、両者間を螺着締結すればよい。
【００１１】
【発明の作用・効果】
本発明のオイルクーラ内蔵ラジエータの樹脂製タンクは、その側壁外面にオイルパイプ把持用の一対のフック状の第１係止部６，第２係止部７が一体に突設形成され、第１係止部６はそのフック状の開口側がタンク本体１の底面側に向き、第２係止部７はそのフック状の開口側がそれとは逆向きに配置されているから、その一対の第１係止部６，第２係止部７によってオイルパイプ５を確実に把持することができる。しかも第１係止部６，第２係止部７の開口側は、タンク本体１の射出成形の際の、雄金型と雌金型との金型分割方向に一致しているため、それらの一体成形が容易となる。
【００１２】
請求項２に記載の本発明は、第３係止部８を設けてオイルパイプ５の外周の一部を把持するようにしたから、更にオイルパイプ５を確実に把持することができる。
