Description

本発明は、車両の自動変速機等におけるオイルパイプ配管構造に関する。   The present invention relates to an oil pipe piping structure in an automatic transmission or the like of a vehicle.

車両用の自動変速機では、潤滑や摩擦締結装置のピストン駆動用としてオイルポンプからのオイルを種々の必要部位へ供給するため、変速機ケースおよびこれに取り付けられるコントロールバルブボディ内に孔を形成し、あるいは変速機ケースとコントロールバルブボディの合わせ面に溝を形成して、油路としている。
しかし、油路形成部位の制約によっては長い距離区間に渡る経路を孔や溝で通すことができない場合があり、この場合には例えば特開２００６−７０９１２号公報に示されるように、離間した位置に開口する２つの油路間をオイルパイプで接続することが行われる。 In an automatic transmission for a vehicle, a hole is formed in a transmission case and a control valve body attached to the transmission case in order to supply oil from an oil pump to various necessary parts for driving a piston of a lubrication or friction fastening device. Alternatively, a groove is formed in the mating surface of the transmission case and the control valve body to form an oil passage.
However, depending on the restriction of the oil passage formation site, there may be a case where a route over a long distance section cannot be passed through a hole or a groove. In this case, as shown in, for example, Japanese Patent Application Laid-Open No. 2006-70912, the separated positions The two oil passages that are open to each other are connected by an oil pipe.

特開２００６−７０９１２号公報JP 2006-70912 A

特開２００６−７０９１２号公報に示された配管では、オイルパイプで接続する潤滑用の２つの油路が変速機ケース（ハウジング）の軸方向端板に形成されて、互いに平行で同方向に開口している。そして、油路の開口端に挿し込まれるオイルパイプの両端も本体部から同方向に曲げられて互いに平行に形成され、オイルパイプの両端を同時に両油路に挿入することが可能となっている。
２つの油路を接続した状態では、オイルパイプの両端は油路の開口面から所定量が外方に延びて、オイルパイプの本体部も油路が開口する軸方向端板から軸方向に突き出た位置となる。 In the piping disclosed in Japanese Patent Application Laid-Open No. 2006-70912, two oil passages for lubrication connected by an oil pipe are formed in an axial end plate of a transmission case (housing) and are opened in parallel and in the same direction. doing. And both ends of the oil pipe inserted into the opening end of the oil passage are also bent in the same direction from the main body portion and formed in parallel to each other, and both ends of the oil pipe can be simultaneously inserted into both oil passages. .
In the state where two oil passages are connected, both ends of the oil pipe extend outward by a predetermined amount from the opening surface of the oil passage, and the main body of the oil pipe also protrudes axially from the axial end plate where the oil passage opens. It becomes the position.

ところが、オイルパイプが油路の開口面から突き出た位置となることが他の部材との干渉などの理由で許されない場合には、２つの油路を同方向に開口させて、両端を同方向に延ばしたオイルパイプを挿し込む構造は採用できない。
この場合には、他の部材との干渉がない面に油路を開口する必要があり、その結果、オイルパイプで接続すべき２つの油路は互いに異なる向きに開口させることとなる。
例えば２つの油路が互いに対向する面に開口する場合、両油路内に挿し込まれるオイルパイプの両端間の距離は対向する開口面間の距離よりも当然に長くなる。しかしながら、一般に銅など金属製のオイルパイプは一旦形状が決まると弾性部材とは異なり変形の自由度が極めて小さいので、撓ませて油路に挿入することは実際には困難であった。
この問題はオイルパイプの両端を挿入しようとする油路が互いに対向する面に開口、すなわち逆方向に開口する場合だけでなく、互いに異なる方向に開口していればいずれも同様に生じるため、オイルパイプを含むオイル供給系はその適用範囲が限られていた。 However, when the oil pipe is not allowed to protrude from the opening surface of the oil passage due to interference with other members, the two oil passages are opened in the same direction, and both ends are in the same direction. It is not possible to adopt a structure that inserts an oil pipe extended to
In this case, it is necessary to open the oil passage on a surface that does not interfere with other members. As a result, the two oil passages to be connected by the oil pipe are opened in different directions.
For example, when two oil passages open to surfaces facing each other, the distance between both ends of the oil pipe inserted into both oil passages is naturally longer than the distance between the opposing opening surfaces. However, in general, once the shape of a metal oil pipe such as copper is determined, unlike an elastic member, the degree of freedom of deformation is extremely small, so it is actually difficult to bend it into the oil passage.
This problem occurs not only when the oil passages into which both ends of the oil pipe are to be inserted are opened on opposite surfaces, that is, in opposite directions, but also when they are opened in different directions. The oil supply system including the pipe has a limited range of application.

したがって本発明は、２つの油路が互いに異なる方向に開口していても、オイルパイプを作業性良く組み付けられるオイルパイプ配管構造を提供することを目的とする。   Therefore, an object of the present invention is to provide an oil pipe piping structure in which an oil pipe can be assembled with good workability even if two oil passages are opened in different directions.

このため本発明は、変速機におけるオイル供給側とオイル受け側の間をオイルパイプで接続するオイルパイプ配管構造であって、オイルパイプが、オイル供給側の部位に形成された第１のパイプ挿通孔に一端が挿し込まれる第１パイプと、オイル受け側の部位に形成された第２のパイプ挿通孔に一端が挿し込まれる第２パイプとからなり、第１パイプの他端および第２パイプの他端の一方が他方の管内に挿し込まれて嵌合連結部を形成しているものとした。   For this reason, the present invention is an oil pipe piping structure in which an oil pipe is connected between an oil supply side and an oil receiving side in a transmission, and the oil pipe is formed in a first pipe insertion formed in a portion on the oil supply side. A first pipe having one end inserted into the hole, and a second pipe having one end inserted into a second pipe insertion hole formed at a site on the oil receiving side, the other end of the first pipe and the second pipe One of the other ends is inserted into the other tube to form a fitting connection portion.

本発明によれば、第１のパイプ挿通孔と第２のパイプ挿通孔が油路形成ブロック２０と油路形成ブロック３０の互いに対向する壁面に開口するなど異なる方向に開口していても、第１パイプと第２パイプをスライドさせることによりオイルパイプを作業性良く確実に組み付けることができる。   According to the present invention, even if the first pipe insertion hole and the second pipe insertion hole are opened in different directions such as opening on the mutually opposing wall surfaces of the oil passage forming block 20 and the oil passage forming block 30, By sliding the first pipe and the second pipe, the oil pipe can be reliably assembled with good workability.

以下、本発明の実施の形態について説明する。
図１は本発明が適用される自動変速機の変速機ケース１０を下方から見た図である。
変速機ケース１０の周縁は閉じたフランジ１１で囲まれ、不図示のオイルパンの取り付け面となるフランジ面１１ａにはオイルパンを取り付けるためのネジ孔１２が所定間隔で設けられている。
なお、後述するオイルパイプ５の取り付け作業は変速機ケース１０を上下反転させてフランジ面１１ａを上にした状態で行うので、図１は当該作業時状態における上面図となる。以下の説明では作業時状態に基づいてフランジ１１側を上方として説明する。 Embodiments of the present invention will be described below.
FIG. 1 is a view of a transmission case 10 of an automatic transmission to which the present invention is applied as viewed from below.
The periphery of the transmission case 10 is surrounded by a closed flange 11, and screw holes 12 for attaching the oil pan are provided at predetermined intervals on a flange surface 11 a serving as an oil pan attachment surface (not shown).
Note that the oil pipe 5 mounting operation described later is performed with the transmission case 10 turned upside down and the flange surface 11a facing upward, so FIG. 1 is a top view of the working state. In the following description, the flange 11 side is described as the upper side based on the working state.

変速機ケース１０は図１における左側を前方、右側を後方とし、前後軸ＣＬを軸心とする部分円筒状の隔壁１４がフランジ面１１ａより下方において上方（紙面手前側）に膨らんでおり、隔壁１４の下側（紙面奥側）にギアや摩擦締結装置のドラム、クラッチ板など変速機構の回転体を収容する回転体収容空間Ｓが形成されている。（後掲の図２、図３参照）
隔壁１４からは油路形成ブロック２０、３０が立ち上がっている。油路形成ブロック２０、３０の上面２１、３１は変速機ケース１０に取り付けられる不図示のコントロールバルブボディとの合わせ面となっており、これらの上面２１、３１にコントロールバルブボディの油路と連通しあるいは連通しないように配置された複数の油路（孔、溝）が開口している。
とくに、前方の油路形成ブロック２０には不図示のオイルポンプの出力側に連通する油路（溝）２３が設けられている。 The transmission case 10 has a partially cylindrical partition wall 14 with the left side in FIG. 1 as the front and the right side as the rear and the front and rear shafts CL as the center, and bulges upward (on the front side of the page) below the flange surface 11a. A rotating body housing space S for housing a rotating body of a speed change mechanism such as a gear, a drum of a friction fastening device, and a clutch plate is formed below 14 (back side in the drawing). (See Figures 2 and 3 below)
From the partition wall 14, oil passage forming blocks 20 and 30 are raised. Upper surfaces 21 and 31 of the oil passage forming blocks 20 and 30 are mating surfaces with a control valve body (not shown) attached to the transmission case 10, and the upper surfaces 21 and 31 communicate with the oil passages of the control valve body. However, a plurality of oil passages (holes, grooves) arranged so as not to communicate with each other are opened.
In particular, an oil passage (groove) 23 communicating with the output side of an oil pump (not shown) is provided in the front oil passage forming block 20.

油路形成ブロック２０、３０の上面２１、３１はフランジ面１１ａよりも低い位置にある。
隔壁１４には油路形成ブロック２０と後方の油路形成ブロック３０の間に、回転体収容空間Ｓとオイルパン側とを連通する窓部１５が開口している。
変速機ケース１０における隔壁１４と右側の側壁１３との間には補強リブ１６（１６ａ、１６ｂ、１６ｃ）が設けられている。
図２は図１におけるＡ−Ａ部の拡大断面図で、補強リブ１６ａを示す。ただし、フランジ面１１ａを上にして示している。
補強リブ１６ａはその上縁が側壁１３の傾斜部に沿って下方へ延びたあと、その下底部がフランジ面１１ａと平行に延びて隔壁１４に達して終わっている。他の補強リブ１６ｂ、１６ｃも同様である。 The upper surfaces 21 and 31 of the oil passage forming blocks 20 and 30 are at a position lower than the flange surface 11a.
In the partition wall 14, a window portion 15 is provided between the oil passage forming block 20 and the rear oil passage forming block 30 so as to communicate the rotating body accommodation space S and the oil pan side.
Reinforcing ribs 16 (16a, 16b, 16c) are provided between the partition wall 14 and the right side wall 13 in the transmission case 10.
FIG. 2 is an enlarged cross-sectional view of the AA portion in FIG. 1 and shows the reinforcing rib 16a. However, the flange surface 11a is shown upward.
The reinforcing rib 16a has its upper edge extending downward along the inclined portion of the side wall 13, and then its lower bottom portion extends in parallel with the flange surface 11a to reach the partition wall 14. The same applies to the other reinforcing ribs 16b and 16c.

実施の形態は、上述した既存の変速機ケース１０をベースにして、回転体収容空間Ｓの後部にとくに積極的にクラッチ板部へのオイル供給を要する不図示の摩擦締結装置を配置した機種を構成するため、変速機ケース１０の前部から後部へオイルを供給する後述のオイルパイプ５を追加的に配管するものである。
このため、後方の油路形成ブロック３０には、その上面３１から回転体収容空間Ｓに向けた孔を形成して、回転体収容空間Ｓの後部に配置される摩擦締結装置のクラッチ板潤滑部に連通する油路３３としている。そして、この油路３３と前方の油路形成ブロック２０の油路２３とをオイルパイプ５で接続する。 The embodiment is based on the existing transmission case 10 described above, and a model in which a friction fastening device (not shown) that needs to actively supply oil to the clutch plate portion is arranged in the rear portion of the rotating body housing space S is arranged. In order to configure, an oil pipe 5 to be described later for supplying oil from the front part to the rear part of the transmission case 10 is additionally provided.
For this reason, the rear oil passage forming block 30 is formed with a hole from its upper surface 31 toward the rotating body accommodation space S, and is disposed at the rear part of the rotating body accommodation space S. The oil passage 33 communicates with the oil passage 33. The oil passage 33 and the oil passage 23 of the oil passage forming block 20 in front are connected by the oil pipe 5.

図３は図１におけるＢ−Ｂ部の断面図で、前側の油路形成ブロック２０の油路２３等を示す。
油路形成ブロック２０には油路（溝）２３の底部に向けて後上方から斜めにパイプ挿通孔２５が形成され、油路２３と連通させてある。
パイプ挿通孔２５は後側の油路形成ブロック３０と対向する後壁面２２ｂに開口し、図１の平面図において前後軸ＣＬと平行で、図３の断面図においてフランジ面１１ａに対する傾斜角度を３０°としてある。
パイプ挿通孔２５が斜めに形成されているのは、孔あけドリルの把持部が隔壁１４や補強リブ１６と干渉するためにフランジ面１１ａと平行に加工できないためである。 3 is a cross-sectional view taken along the line BB in FIG. 1 and shows the oil passage 23 and the like of the front oil passage forming block 20.
In the oil passage forming block 20, a pipe insertion hole 25 is formed obliquely from the rear upper direction toward the bottom of the oil passage (groove) 23, and communicates with the oil passage 23.
The pipe insertion hole 25 opens to the rear wall surface 22b facing the rear oil passage forming block 30, and is parallel to the front / rear axis CL in the plan view of FIG. 1, and has an inclination angle of 30 with respect to the flange surface 11a in the sectional view of FIG. It is as °.
The reason why the pipe insertion hole 25 is formed obliquely is that the gripping portion of the drilling drill interferes with the partition wall 14 and the reinforcing rib 16 and cannot be processed in parallel with the flange surface 11a.

図４は図１におけるＣ−Ｃ部の拡大断面図で、油路形成ブロック３０の油路３３を示す。
油路形成ブロック３０には油路３３を横切るようにフランジ面１１ａと平行なパイプ挿通孔３５が形成され、油路３３と連通させるとともに、前側の油路形成ブロック２０と対向する前壁面３２ａから後壁面３２ｂまで貫通して開口させてある。
なお、パイプ挿通孔３５の形成は、変速機ケース１０鋳造時に後端壁１８に形成されている抜き孔１９を通して、外方からのドリル加工により行う。 FIG. 4 is an enlarged cross-sectional view of the CC section in FIG. 1 and shows the oil passage 33 of the oil passage forming block 30.
A pipe insertion hole 35 parallel to the flange surface 11 a is formed in the oil passage forming block 30 so as to cross the oil passage 33, and communicates with the oil passage 33 and from the front wall surface 32 a facing the front oil passage forming block 20. The rear wall surface 32b is penetrated and opened.
The pipe insertion hole 35 is formed by drilling from the outside through the through hole 19 formed in the rear end wall 18 when the transmission case 10 is cast.

なお、補強リブ１６ａと補強リブ１６ｂの間に配置された支持ボス４０ｂは窓部１５に隣接しているので、側壁１３との間にリブ１７を備えている。 As shown in FIG. 1, along the right side wall 13 of the transmission case 10, support bosses 40 a, 40 b, and 40 c for supporting the oil pipe 5 are provided using protrusions from the partition wall 14.
FIG. 5 is an enlarged cross-sectional view of a DD portion in FIG. 1 and shows a support boss 40a. However, the flange surface 11a is shown upward.
As shown in FIG. 5, the support boss 40a disposed between the oil passage forming block 20 on the front side and the reinforcing rib 16a includes a rib 17 extending left and right between the side wall 13 and the inclined partition wall 14. The same applies to the support boss 40c at the rear end of the transmission case 10.
Since the support boss 40b disposed between the reinforcing rib 16a and the reinforcing rib 16b is adjacent to the window portion 15, the rib 17 is provided between the side wall 13 and the supporting boss 40b.

第２パイプ６０の長尺部６１を第１パイプ５０の長尺部５３に挿入した状態で、挿入部６３をその貫通孔６４が油路形成ブロック３０の油路３３（図１参照）に整合する位置までパイプ挿通孔３５に挿し込んだとき、ブラケット６６、６９の取り付け部６７ａ、６７ｂが支持ボス４０ｃ、４０ｄの上端面４１ｃ、４１ｄに着座するとともに、各取り付け部６７ａ、６７ｂの孔６８が支持ボス４０ｃ、４０ｄのネジ孔４２に整合するように設定される。 In the plan view of (a), the bracket 66 extends obliquely rearward perpendicularly to the extending direction of the intermediate region 62b, and is provided with a hole 68 through which the bolt 7 passes through the mounting portion 67a parallel to the flange surface 11a.
In the plan view, the bracket 69 is also provided with a hole 68 that extends perpendicularly to the extending direction of the intermediate region 62d, that is, rearward, and penetrates the bolt 7 in the mounting portion 67b parallel to the flange surface 11a.
With the elongated portion 61 of the second pipe 60 inserted into the elongated portion 53 of the first pipe 50, the insertion portion 63 is aligned with the oil passage 33 (see FIG. 1) of the oil passage forming block 30.

It is set to be located outward (rear).
As will be described later, the long portion 61 of the second pipe 60 is inserted into the long portion 53 of the first pipe 50. The radial gap between the inner diameter of the region of length G and the outer diameter of the region of a predetermined length H from the front end of the long portion 61 to the vicinity of the connecting portion with the intermediate portion 62 is set to be 0.01 mm or more. It is.

つぎに、オイルパイプ５の組み付け要領について説明する。
まず、第１パイプ５０の長尺部５３に第２パイプ６０の長尺部６１をその根元近くまで挿入して、両パイプ５０、６０を仮連結する。両長尺部５３、６１間の径方向間隙は最小でも０．０１ｍｍあるので、滑らかに相互スライド可能である。
これにより、オイルパイプ５は変速機ケース１０内の前後の油路形成ブロック２０、３０間に落とし込んで取り扱うことができる。 Next, the procedure for assembling the oil pipe 5 will be described.
First, the long portion 61 of the second pipe 60 is inserted to the long portion 53 of the first pipe 50 to the vicinity thereof, and both the pipes 50 and 60 are temporarily connected. Since the radial gap between the long portions 53 and 61 is at least 0.01 mm, they can be slid smoothly.
As a result, the oil pipe 5 can be handled by being dropped between the front and rear oil passage forming blocks 20 and 30 in the transmission case 10.

次に、第１パイプ５０の長尺部５３を変速機ケース１０のフランジ面１１ａと平行に保持しながら、第１パイプ５０の挿入部５１を前側の油路形成ブロック２０のパイプ挿通孔２５に斜めに挿し込む。パイプ挿通孔２５と挿入部５１間の径方向間隙は最小でも０．０２ｍｍあるので、斜め方向でも滑らかに挿し込み可能である。   Next, while holding the long portion 53 of the first pipe 50 parallel to the flange surface 11a of the transmission case 10, the insertion portion 51 of the first pipe 50 is inserted into the pipe insertion hole 25 of the oil passage forming block 20 on the front side. Insert it diagonally. Since the radial gap between the pipe insertion hole 25 and the insertion portion 51 is at least 0.02 mm, it can be smoothly inserted even in an oblique direction.

図９は第１パイプ５０の挿入部５１が油路形成ブロック２０のパイプ挿通孔２５に挿し込まれた状態を示す平面図である。
図１０は挿入部５１が挿し込まれたパイプ挿通孔２５に沿う断面を含む側面図である。
挿入部５１がパイプ挿通孔２５に所定量挿し込まれると、第１パイプ５０のブラケット５４、５８（の取り付け部５６ａ、５６ｂ）が支持ボス４０ａ、４０ｂに着座するので、ボルト７でブラケット５４、５８を支持ボス４０ａ、４０ｂに緩めに仮止めする。 FIG. 9 is a plan view showing a state where the insertion portion 51 of the first pipe 50 is inserted into the pipe insertion hole 25 of the oil passage forming block 20.
FIG. 10 is a side view including a cross section along the pipe insertion hole 25 into which the insertion portion 51 is inserted.
When the insertion portion 51 is inserted into the pipe insertion hole 25 by a predetermined amount, the brackets 54 and 58 (attachment portions 56a and 56b) of the first pipe 50 are seated on the support bosses 40a and 40b. 58 is temporarily fixed loosely to the support bosses 40a and 40b.

つぎに、第２パイプ６０をスライドさせてその長尺部６１を第１パイプ５０の長尺部５３から後方に引き出して、第２パイプ６０の挿入部６３を後側の油路形成ブロック３０のパイプ挿通孔３５に挿し込む。
パイプ挿通孔３５と挿入部６３間の径方向間隙は最小でも０．０１ｍｍあるので、滑らかに挿し込み可能である。 Next, the second pipe 60 is slid and the long portion 61 is pulled backward from the long portion 53 of the first pipe 50, and the insertion portion 63 of the second pipe 60 is moved to the rear oil passage forming block 30. Insert into the pipe insertion hole 35.
Since the radial gap between the pipe insertion hole 35 and the insertion portion 63 is at least 0.01 mm, it can be smoothly inserted.

挿入部６３の挿し込みに従ってブラケット６６、６９の取り付け部６７ａ、６７ｂが滑りながら支持ボス４０ｃ、４０ｄに着座するので、取り付け部６７ａ、６７ｂの孔６８が支持ボス４０ｃ、４０ｄのネジ孔４２に整合したところで、ボルト７をネジ孔４２に締め込んでブラケット６６、６９を支持ボス４０ｃ、４０ｄに固定する。
なお、第１パイプ５０の長尺部５３と第２パイプ６０の長尺部６１の長さは、挿入部６３をパイプ挿通孔３５に挿し込み後の状態においても、第１パイプ５０の長尺部５３内への挿入状態を保持して嵌合連結部Ｗを形成しているように設定されている。 Since the attachment portions 67a and 67b of the brackets 66 and 69 slide on the support bosses 40c and 40d as the insertion portion 63 is inserted, the holes 68 of the attachment portions 67a and 67b are aligned with the screw holes 42 of the support bosses 40c and 40d. The bolt 7 is then tightened into the screw hole 42 to fix the brackets 66 and 69 to the support bosses 40c and 40d.
Note that the length of the long portion 53 of the first pipe 50 and the length of the long portion 61 of the second pipe 60 are the same as those of the first pipe 50 even after the insertion portion 63 is inserted into the pipe insertion hole 35. It is set so that the fitting connection portion W is formed while the insertion state into the portion 53 is maintained.

これにより、パイプ挿通孔３５に沿う断面図である図１１に示すように、挿入部６３の貫通孔６４油路形成ブロック３０の油路３３に整合し、第２パイプ６０内と油路３３とが連通する。貫通孔６４は図中クラッチ板潤滑部に連通する下方に向いて開口している。
最後に第１パイプ５０のブラケット５４、５８を仮止めしていたボルト７を締め込んで、支持ボス４０ａ、４０ｂに固定することにより、オイルパイプ５の組み付け作業を完了する。
なお、油路形成ブロック３０の上面３１における油路３３の開口は当該油路形成ブロック上面３１に当接して重ねられるコントロールバルブボディによって閉じられる。 Thereby, as shown in FIG. 11 which is a cross-sectional view along the pipe insertion hole 35, it is aligned with the oil passage 33 of the through hole 64 oil passage forming block 30 of the insertion portion 63, and the inside of the second pipe 60 and the oil passage 33 are aligned. Communicate. The through hole 64 opens downward in communication with the clutch plate lubricating portion in the figure.
Finally, the bolt 7 that temporarily holds the brackets 54 and 58 of the first pipe 50 is tightened and fixed to the support bosses 40a and 40b, thereby completing the assembling work of the oil pipe 5.
The opening of the oil passage 33 on the upper surface 31 of the oil passage forming block 30 is closed by a control valve body that is in contact with and overlaps the upper surface 31 of the oil passage forming block.

図１２は以上のように組み付けられたオイルパイプ５の配管状態を示す平面図である。
これにより、オイルポンプの出力側に連通する油路２３が設けられた前方の油路形成ブロック２０とクラッチ板潤滑部に連通する油路３３が設けられた後方の油路形成ブロック３０の間がオイルパイプ５で接続され、他の経路ではオイル供給が困難なクラッチ板潤滑部であってもオイルポンプからの十分なオイルが供給される。
また、図１１に示されるように、第２パイプ６０の挿入部６３の後端が封止部６５として閉じられているので、パイプ挿通孔３５の後壁面３２ｂにおける開口部を別部品のプラグ等で塞ぐ必要がない。 FIG. 12 is a plan view showing a piping state of the oil pipe 5 assembled as described above.
As a result, the gap between the front oil passage forming block 20 provided with the oil passage 23 communicating with the output side of the oil pump and the rear oil passage forming block 30 provided with the oil passage 33 communicating with the clutch plate lubricating portion is established. Even if it is a clutch plate lubrication part which is connected by the oil pipe 5 and is difficult to supply oil in other paths, sufficient oil is supplied from the oil pump.
Further, as shown in FIG. 11, since the rear end of the insertion portion 63 of the second pipe 60 is closed as a sealing portion 65, the opening portion in the rear wall surface 32b of the pipe insertion hole 35 is plugged as a separate part. There is no need to close with.

なお、オイルパイプ５の各部位のサイズ（組み付け状態の長尺部５３と長尺部６１の嵌合領域における長尺部５３の内径と長尺部６１の外径、パイプ挿通孔２５の内径と挿入部５１の外径、パイプ挿通孔３５の内径と挿入部６３の外径）については、各部位で滑らかなスライドあるいは挿し込みを確保する観点での径方向間隙の最小値を例示したが、各径の公差はオイルの径方向間隙からの漏れを考慮して設定される。
オイル漏れ量は所定の油圧の下で挿し込み部分の径方向間隙によって変化するので、径方向間隙を決定づけるパイプ径の公差によってオイル漏れを規制する。もちろん、嵌合連結部Ｗなど挿し込み部分の長さが大きいほど漏れに対する抵抗も大きくなるので、オイルパイプ５の配管環境の中では所定範囲に制約されるが公差で規定した径方向間隙部分の長さも考慮する。 The size of each part of the oil pipe 5 (the inner diameter of the elongated portion 53 and the outer diameter of the elongated portion 61 in the fitting region of the elongated portion 53 and the elongated portion 61 in the assembled state, the inner diameter of the pipe insertion hole 25, As for the outer diameter of the insertion portion 51, the inner diameter of the pipe insertion hole 35, and the outer diameter of the insertion portion 63), the minimum value of the radial gap in terms of ensuring smooth sliding or insertion at each part is illustrated. The tolerance of each diameter is set in consideration of leakage from the radial gap of oil.
Since the amount of oil leakage varies depending on the radial gap of the insertion portion under a predetermined oil pressure, the oil leakage is regulated by the tolerance of the pipe diameter that determines the radial gap. Of course, the greater the length of the insertion portion such as the fitting connection portion W, the greater the resistance to leakage. Therefore, in the piping environment of the oil pipe 5, the radial gap portion defined by the tolerance is limited to a predetermined range. Consider length.

具体的には、オイル漏れは長尺部５３、６１間の嵌合連結部Ｗ、挿入部５１と油路形成ブロック２０のパイプ挿通孔２５間、および挿入部６３と油路形成ブロック３０のパイプ挿通孔３５間の３箇所に生じるので、３箇所のそれぞれにおける径方向間隙が各部位の公差による最大のときでも、オイルポンプから油路形成ブロック２０の油路２３に供給される所定のオイル量から上記３箇所のオイル漏れ量を減じた値がクラッチ板潤滑部への必要オイル量より低くならないように、各公差を設定すればよい。
以上を換言すれば、各部位のサイズの公差は組み付けの際のスライド容易性と組み付け後のオイル漏れ量規制が両立するように設定されるが、概ね径方向間隙が最大０．３ｍｍ以下となるようにするのが好ましい。 Specifically, the oil leakage is caused by the fitting connection portion W between the long portions 53 and 61, between the insertion portion 51 and the pipe insertion hole 25 of the oil passage forming block 20, and the pipe of the insertion portion 63 and the oil passage formation block 30. Since it occurs at three locations between the insertion holes 35, a predetermined amount of oil supplied from the oil pump to the oil passage 23 of the oil passage formation block 20 even when the radial gap at each of the three locations is the maximum due to the tolerance of each portion. Each tolerance may be set so that the value obtained by subtracting the oil leakage amount at the three locations from the above does not become lower than the required oil amount to the clutch plate lubricating portion.
In other words, the tolerance of the size of each part is set so that the ease of sliding during assembly and the regulation of the amount of oil leakage after assembly are compatible, but the radial clearance is generally at most 0.3 mm or less. It is preferable to do so.

本実施の形態では、油路形成ブロック２０が発明におけるオイル供給側の部位、および第１の油路形成ブロックに該当し、油路形成ブロック３０がオイル受け側の部位、および第２の油路形成ブロックに該当する。クラッチ板潤滑部がオイル必要部位に該当する。

Corresponds to the building block. The clutch plate lubrication part corresponds to the oil required part.

Further, the insertion portion 51 corresponds to one end of the first pipe, the long portion 53 is the other end of the first pipe, the insertion portion 63 is one end of the second pipe, and the long portion 61 is the other end of the second pipe. It corresponds to each end.

実施の形態は以上のように構成され、それぞれ変速機ケースの隔壁に形成されてオイルポンプの出力側に連通する油路２３を備えるオイル供給側の油路形成ブロック２０と、クラッチ板潤滑部側に連通する油路３３を備えるオイル受け側の油路形成ブロック３０との間を接続するオイルパイプ５が、油路形成ブロック２０に形成されたパイプ挿通孔２５に一端の挿入部５１が挿し込まれる第１パイプ５０と、油路形成ブロック３０に形成されたパイプ挿通孔３５に一端の挿入部６３が挿し込まれる第２パイプ６０とからなり、第１パイプ５０の他端の長尺部５３の管内に第２パイプ６０の他端の長尺部６１が挿し込まれて嵌合連結部Ｗを形成しているものとしたので、パイプ挿通孔２５とパイプ挿通孔３５が油路形成ブロック２０と油路形成ブロック３０の互いに対向する壁面に開口していても、第１パイプ５０と第２パイプ６０をスライドさせることによりオイルパイプ５を作業性良く確実に組み付けることができる。（請求項１、２および５に対応する効果）   The embodiment is configured as described above, and the oil passage forming block 20 on the oil supply side including the oil passage 23 formed in the partition wall of the transmission case and communicating with the output side of the oil pump, and the clutch plate lubricating portion side The oil pipe 5 connecting between the oil receiving side oil passage forming block 30 provided with the oil passage 33 communicating with the oil passage 33 is inserted into the pipe insertion hole 25 formed in the oil passage forming block 20 at one end. The first pipe 50 and the second pipe 60 into which the insertion portion 63 at one end is inserted into the pipe insertion hole 35 formed in the oil passage forming block 30, and the long portion 53 at the other end of the first pipe 50. Since the elongated portion 61 at the other end of the second pipe 60 is inserted into the pipe to form the fitting connection portion W, the pipe insertion hole 25 and the pipe insertion hole 35 are formed by the oil passage forming block 20. And oil passage formation Be opened in opposing walls of the lock 30, the oil pipe 5 can be assembled reliably good workability by sliding the first pipe 50 and the second pipe 60. (Effects corresponding to claims 1, 2 and 5)

油路形成ブロック３０のパイプ挿通孔３５は第２パイプ６０の挿入部６３の挿し込み側とは反対側の後壁面からの貫通孔加工により形成し、挿入部６３の管壁にはパイプ挿通孔３５が接続するクラッチ板潤滑部側に連通する油路３３に整合する貫通孔６４を形成するとともに、挿入部６３の先端にはその管内と外部とを遮断する封止部６５を設けているので、第２パイプ６０はその貫通孔６４を通じて油路３３と連通する一方、油路形成ブロック３０の後壁面におけるパイプ挿通孔３５の開口を塞ぐプラグ等の部品を不要としている。（請求項３に対応する効果）
また、封止部６５は、挿入部６３の管壁を径方向一方の側から他方の側へ断面円弧状に押し潰して形成してあるので、その外周面は挿入部６３の前部の断面内に収まり、パイプ挿通孔３５への挿入に支障を生じない。（請求項４に対応する効果） The pipe insertion hole 35 of the oil passage forming block 30 is formed by through-hole processing from the rear wall surface opposite to the insertion side of the insertion portion 63 of the second pipe 60, and the pipe insertion hole is formed in the tube wall of the insertion portion 63. Since a through hole 64 is formed in alignment with the oil passage 33 communicating with the clutch plate lubrication portion side to which 35 is connected, and a sealing portion 65 is provided at the distal end of the insertion portion 63 to block the inside of the pipe from the outside. The second pipe 60 communicates with the oil passage 33 through the through-hole 64, while eliminating the need for parts such as a plug for closing the opening of the pipe insertion hole 35 on the rear wall surface of the oil passage forming block 30. (Effects corresponding to claim 3)
Further, since the sealing portion 65 is formed by crushing the tube wall of the insertion portion 63 from one side in the radial direction to the other side in a circular arc shape, the outer peripheral surface thereof is a cross section of the front portion of the insertion portion 63. It fits in and does not hinder the insertion into the pipe insertion hole 35. (Effects corresponding to claim 4)

なお、実施の形態は、既存の変速機ケースをベースにして新たな変速機を構成する例で、限定された支持ボス４０の形成位置に対応して第１パイプ５０の長尺部５３に２つのブラケット５４、５８を備えるものとしたので、当該長尺部５３を根元近くまで第２パイプ６０に挿し込むことができず、結果として第１パイプ５０を太径、第２パイプ６０を細径としたが、変速機ケース１０を新規設計する場合には支持ボス４０の新たな配置設定により、オイルの上流となる前側の第１パイプ５０を細径とし、下流側となる第２パイプ６０を太径とすることができる。これによれば、両パイプ５０、６０の長尺部間の径方向間隙がオイルの流れに向かって開口しないので、当該径方向間隙からのオイル漏れが低減する。   The embodiment is an example in which a new transmission is configured based on an existing transmission case, and the length of the elongated portion 53 of the first pipe 50 is set to 2 corresponding to the limited formation position of the support boss 40. Since the two brackets 54 and 58 are provided, the long portion 53 cannot be inserted into the second pipe 60 to the vicinity of the root, and as a result, the first pipe 50 has a large diameter and the second pipe 60 has a small diameter. However, when the transmission case 10 is newly designed, the first pipe 50 on the front side, which is upstream of the oil, has a small diameter and the second pipe 60, which is on the downstream side, is changed by a new arrangement setting of the support boss 40. The diameter can be large. According to this, since the radial gap between the long portions of the pipes 50 and 60 does not open toward the oil flow, oil leakage from the radial gap is reduced.

実施の形態におけるオイルパイプ５（第１パイプ５０、第２パイプ６０）の形状やサイズに係る数値はあくまでも例示であり、変速機の機種や実際の変速機ケースの形態に応じて適宜に変更可能である。
また、パイプ挿通孔２５とパイプ挿通孔３５は油路形成ブロック２０と油路形成ブロック３０の互いに対向する後壁面２２ｂと前壁面３２ａに開口するものとしたが、本発明はこれに限定されず、例えば一方の油路形成ブロック２０のパイプ挿通孔２５がその後壁面２２ｂに開口し、他方の油路形成ブロック３０のパイプ挿通孔３５が上記後壁面２２ｂとは対向しない側壁面３２ｃに開口する場合にも、スライド可能な嵌合連結部を有することによりオイルパイプ５の両端を各パイプ挿通孔２５、３５に挿し込んで接続することができる。 The numerical values related to the shape and size of the oil pipe 5 (first pipe 50, second pipe 60) in the embodiment are merely examples, and can be changed as appropriate according to the type of transmission and the form of the actual transmission case. It is.
Moreover, although the pipe insertion hole 25 and the pipe insertion hole 35 shall open to the back wall surface 22b and the front wall surface 32a which the oil path formation block 20 and the oil path formation block 30 mutually oppose, this invention is not limited to this. For example, when the pipe insertion hole 25 of one oil passage forming block 20 is subsequently opened in the wall surface 22b, and the pipe insertion hole 35 of the other oil passage formation block 30 is opened in the side wall surface 32c not facing the rear wall surface 22b. In addition, by having a slidable fitting connection portion, both ends of the oil pipe 5 can be inserted and connected to the pipe insertion holes 25 and 35.

油路形成ブロック３０のパイプ挿通孔３５を第２パイプ６０の挿入部６３が挿し込まれる側とは反対の外部からの貫通孔加工により形成する一方、第２パイプ６０の挿入部６３後端を押し潰して封止部６５とすることにより、貫通孔加工による挿入部６３挿し込み側と反対側の不要孔を塞ぐプラグを不要としたが、これは第２パイプ６０が接続する下流側の油路形成ブロック３０に限らず、上流側の油路形成ブロック２０のパイプ挿通孔２５も、油路形成ブロック２０の形態によっては第１パイプ５０の挿入部５１が挿し込まれる側とは反対側の前壁面２２ａからの貫通孔加工により形成することができ、この場合にも第１パイプ５０の挿入部５１前端を押し潰して同様の封止部とすることにより、不要孔を塞ぐプラグ等を省略することができる。   The pipe insertion hole 35 of the oil passage forming block 30 is formed by the through hole processing from the outside opposite to the side where the insertion part 63 of the second pipe 60 is inserted, while the rear end of the insertion part 63 of the second pipe 60 is formed. By crushing to form the sealing portion 65, the plug that closes the unnecessary hole on the side opposite to the insertion portion 63 insertion side by the through-hole processing is unnecessary, but this is a downstream oil to which the second pipe 60 is connected. Depending on the form of the oil passage forming block 20, the pipe insertion hole 25 of the upstream oil passage forming block 20 is not limited to the side on which the insertion portion 51 of the first pipe 50 is inserted. It can be formed by through-hole processing from the front wall surface 22a. In this case as well, the front end of the insertion portion 51 of the first pipe 50 is crushed to form a similar sealing portion, thereby omitting plugs that close unnecessary holes. To be able to That.

また、実施の形態はオイル必要部位（オイル受け側）が回転体収容空間Ｓの後部に配置される摩擦締結装置のクラッチ板潤滑部である場合を例として説明したが、本発明はこれに限定されず、その他摩擦締結装置のピストン駆動部（シリンダ）などオイル供給が求められる任意の部位をオイル必要部位とする場合にも適用される。
なお、本発明は、互いに異なる方向に開口する２つの油路を接続する場合にとくに有効であるが、互いに平行で同方向に開口する２つの油路を接続する場合にも問題なく適用することができる。 Further, although the embodiment has been described by taking as an example the case where the oil required portion (oil receiving side) is the clutch plate lubricating portion of the frictional fastening device disposed at the rear portion of the rotating body accommodation space S, the present invention is limited to this. However, the present invention is also applied to a case where an oil-required part is used as an arbitrary part for which oil supply is required, such as a piston driving unit (cylinder) of a friction fastening device.
The present invention is particularly effective when connecting two oil passages that open in different directions, but can also be applied without problems when connecting two oil passages that are parallel and open in the same direction. Can do.
