Description

【０００１】
【発明の属する技術分野】
本発明はマニュアルトランスミッションなどのトランスミッションの軸内オイル供給構造に関し、特に該構造が備えるオイルカバーに関する。中でも、本発明は、マニュアルトランスミッションの軸内オイル供給構造において、軸端面からオイルを導くオイルカバーに開口部を形成されているものである。
【０００２】
【従来の技術】
図３は、従来例に係るマニュアルトランスミッションの軸内オイル供給構造が備えるオイルカバーの斜視図であって、オイルカバーの形状とオイルの流れを示している。
【０００３】
図３を参照すると、従来例に係るオイルカバー３５は、マニュアルトランスミッションの軸内へオイルを供給するための中央筒部３５ａと、中央筒部３５ａの半径方向外側に配置されマニュアルトランスミッションのハウジングケースに取付けられる環状部４１と、中央筒部３５ａと環状部４１の間に延在して形成されオイルカバー３５の軸方向に沿って突出し、オイルカバー３５の円周方向に沿って１２０度毎に配置された複数の廻り止め（突出部）４０ａ，４０ｂ，４０ｃと、中央筒部３５ａと環状部４１の間に形成されマニュアルトランスミッションの軸回転方向に沿って（オイルカバー３５円周方向に沿って）順に、突出部４０ａ，４０ｂ同士の間に形成された開口部４３、突出部４０ｂ，４０ｃ同士の間に形成された開口部４４、及び突出部４０ｃ，４０ａ同士の間に形成された扇状側板部４２とを有している。
【０００４】
従来例に係るオイルカバー３５においては、オイル流れ３９で示すように、オイルレシーバーからオイルカバー３５の側面（図３中表側）に供給されるオイルが、中央筒部３５ａを通じて、マニュアルトランスミッションの軸内へ供給される。また、マニュアルトランスミッション軸の回転により、開口部４４を通じてオイルカバー３５（扇状側板部４２）の裏側へ吸い込まれるオイル流れ３８と、開口部４３を通じて排出されるオイル流れ３７が発生する。
【０００５】
【発明が解決しようとする課題】
前記従来例に係るマニュアルトランスミッションの軸内オイル供給構造においては、絶えずオイル流れ３８からオイル流れ３７へのオイルループが形成され、中央筒部３５ａからマニュアルトランスミッション軸内へ導入されるオイル流れ３９が非常に少なくなるという問題点がある。
【０００６】
本発明の目的は、トランスミッションの軸内へ効率よくオイルを導入することができるトランスミッションの軸内オイル供給構造を提供することである。
【０００７】
【課題を解決するための手段】
本発明は、第１の視点において、トランスミッションの軸内へオイルを供給するための構造であって、前記トランスミッションのハウジングケース内に装填され、前記トランスミッションの軸端面に隣接して配置される環状のオイルカバーを備え、前記オイルカバーは、前記オイルカバーの中心部に形成され前記軸に形成された軸内油路と連通する中央筒部と、前記中央筒部内に該中央筒部の軸方向に沿って延在して形成された整流板と、前記中央筒部の半径方向外方に形成され前記ハウジングケースに取付けられる環状部と、前記中央筒部と前記環状部の間に延在して該中央筒部と該環状部を接続するよう形成された複数の中間部と、前記中央筒部と前記環状部の間に形成され前記複数の中間部によって仕切られた複数の開口部と、少なくとも一の前記中間部上に該中間部に隣接する前記開口部の前記トランスミッションの軸回転方向に沿って前方に形成され当該開口部を通過したオイル流れを受け止めて前記中央筒部の前記整流板によって仕切られた一側開口に向かって案内する堰とを有することを特徴とするトランスミッションの軸内オイル供給構造を提供する。
【０００８】
本発明のトランスミッションの軸内オイル供給構造によれば、マニュアルトランスミッションの軸回転方向に沿って開口部の前方に堰を形成することによって、ある開口部からオイルカバーの裏側に流れ、別の開口部からオイルカバーの表側に戻るオイルが効率よく受け止められ、中央筒部の開口からトランスミッション軸内に導かれる。また、中央筒部内に整流板を設けることによって、互いに対向する流れ、例えば、一の開口部から中央筒部の開口に向かう一のオイル流れと、他の開口部から中央筒部の開口に向かう他のオイル流れとの間、又は、例えば、オイルレシーバーから中央筒部の開口に向かう一次的なオイル流れと、ある開口部を通過してから中央筒部の開口に向かう二次的なオイル流れとの間に、流れの阻害（乱流）が発生することが防止される。この結果、オイルカバーの中央筒部内には効率よくオイルが導入される。
【０００９】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を説明する。
【００１０】
本発明の好ましい実施の形態において、少なくとも一の前記堰と前記整流板とが前記オイルカバーの半径方向に沿って連続的に形成されている。
【００１１】
本発明の好ましい実施の形態において、前記中央筒部の前記整流板によって仕切られた一側開口に、前記オイルカバーに供給される一次のオイル流れが導入され、同他側開口に、前記一次のオイル流れから派生した前記開口部を通過した二次的なオイル流れ乃至前記堰によって受け止められた二次的なオイル流れが導入される。
【００１２】
本発明のトランスミッションの軸内オイル供給構造は、マニュアルトランスミッションに好適に適用される。
【００１３】
【実施例】
以上説明した本発明の好ましい実施の形態をさらに明確化するために、以下図面を参照して、本発明の一実施例を説明する。
【００１４】
図１は、本発明の一実施例に係るトランスミッションの軸内オイル供給構造を説明するための断面図である。図２は、図１に示したオイルカバー５の部分斜視図である。なお、本発明の一実施例に係るオイルカバーにおいて、図２に図示した部分以外の形状は、図３に示した従来例に係るオイルカバーと同様である。
【００１５】
図１を参照すると、マニュアルトランスミッションの軸１に対してベアリング３のインナレースが圧入されている。軸１には、ベアリング３の抜け止めとして、スナップリング６が係合している。ベアリング３全体は、ハウジングケース４内に挿入され、ハウジングケース４と係合している。ハウジングケース４のスラスト面とベアリング３のスラスト面との間には、オイルカバー５が挿入されている。これにより、オイルカバー５は、マニュアルトランスミッションのハウジングケース４内に装填されている。オイルカバー５は、オイルレシーバ２からオイルカバー５の側面（中央筒部５ａの外周側）へ流れてくるオイルを受け止め、筒部５ａより軸１内へオイルを導入する。
【００１６】
図２を参照すると、オイルカバー５は、トランスミッションのハウジングケース４内に装填され、トランスミッションの軸端面に隣接して配置されている。オイルカバー５は、オイルカバー５の中心部に形成され前記軸に形成された軸内油路と連通する中央筒部５ａと、中央筒部５ａ内に中央筒部５ａの軸方向に沿って延在して形成された整流板５ｄと、中央筒部５ａの半径方向外方に形成されハウジングケース４に取付けられる環状部５ｆと、中央筒部５ａと環状部５ｆの間に延在して中央筒部５ａと環状部５ｆを接続するよう形成された複数の中間部５ｅと、中央筒部５ａと環状部５ｆの間に形成され複数の中間部５ｅによって仕切られた複数の開口部５ｂと、少なくとも一の中間部５ｅ上に中間部５ｅに隣接する開口部５ｂのトランスミッションの軸回転方向前方に形成され当該開口部５ｂを通過したオイル流れを受け止めて中央筒部５ａの整流板５ｄによって仕切られた一側開口に向かって案内する堰５ｃとを有する。環状部５ｆはハウジングケース４とベアリング３の間に挟持される。
【００１７】
次に、オイルカバー５の機能について詳細に説明する。図１及び図２を参照すると、オイルレシーバー２から供給される一次的なオイル流れが、中央筒部５ａの整流板５ｄによって仕切られた一側開口を通じて、マニュアルトランスミッションの軸内油路に導入される。一方、マニュアルトランスミッションの軸１の回転により、オイルカバー５の裏側へ吸い込まれたオイル流れ８は、新たに形成された開口部５ｂ，５ｂを通じてオイルカバー５の表側に戻り、堰５ｃによって受け止められ、中央筒部５ａの整流板５ｄによって仕切られた他側開口に向かうオイル流れ１０が発生する。堰５ｃの作用によって、オイルカバー５の裏側に排出されるオイル流れ７ａの発生が抑制される。整流板５ｄは、一次的なオイル流れ９と、二次的なオイル流れ１０との間に互いの流れの阻害（乱流）を起こさせない。この結果、中央筒部５ａ内には、効率よくオイルが導入される。

Referring to FIG. 1, an inner race of a bearing 3 is press-fitted into a shaft 1 of a manual transmission. A snap ring 6 is engaged with the shaft 1 to prevent the bearing 3 from coming off. The entire bearing 3 is inserted into the housing case 4 and is engaged with the housing case 4. An oil cover 5 is inserted between the thrust surface of the housing case 4 and the thrust surface of the bearing 3. Thereby, the oil cover 5 is loaded in the housing case 4 of the manual transmission. The oil cover 5 receives the oil flowing from the oil receiver 2 to the side surface of the oil cover 5 (the outer peripheral side of the central cylindrical portion 5a), and introduces the oil into the shaft 1 from the cylindrical portion 5a.
[0016]
Referring to FIG. 2, the oil cover 5 is mounted in the housing case 4 of the transmission, and is disposed adjacent to the shaft end face of the transmission. The oil cover 5 is formed at the center of the oil cover 5 and communicates with an in-shaft oil passage formed on the shaft. The oil cover 5 extends in the center cylinder 5a along the axial direction of the center cylinder 5a. A straightening plate 5d formed in the center, an annular portion 5f formed radially outward of the central cylindrical portion 5a and attached to the housing case 4, and a central portion extending between the central cylindrical portion 5a and the annular portion 5f. A plurality of intermediate portions 5e formed to connect the cylindrical portion 5a and the annular portion 5f, a plurality of openings 5b formed between the central cylindrical portion 5a and the annular portion 5f and partitioned by the plurality of intermediate portions 5e; At least one intermediate portion 5e is formed forward of the opening 5b adjacent to the intermediate portion 5e in the axial rotation direction of the transmission, receives the oil flow passing through the opening 5b, and is partitioned by the rectifying plate 5d of the central cylindrical portion 5a.
