Abstract

A mating plate (20) of a wet-type friction engagement device is composed of more than four axially split annular plates having spline teeth (26). In each of two intermediate plates (22, 22), radially inwardly opened slits (23) and radially outwardly opened slits (24) are alternately formed in the circumferential direction with each of the slits extending beyond the radially center of the slit. When the two intermediate plates (22, 22) are superposed on each other so that they are phase-aligned with each other with the inwardly opened slits (23) and the outwardly opened slits (24) displaced from each other, an oil path running from the radially inside to the outside is formed because of the presence of superposing portions (25). The outer plates (21, 21) having no slits are placed on both outer sides of the intermediate plates (22, 22) having the slits. The intermediate plates (22, 22) having the slits can be simply produced by press punching.

1 0は、 第 4図に示すように、 油圧作動式ピストン 1 1と、 交互に配列されてピ ストン 1 1によって互いに係合させられる複数枚の湿式摩擦板 1 2及びメイテ ィングプレート 1 3とを有してなる。 As shown in FIG. 4, 10 is a hydraulically actuated piston 11, a plurality of wet friction plates 12 2 and mating plates 13 that are alternately arranged and engaged with each other by a piston 11. It has.
湿式摩擦板 1 2は、 フエノール樹脂を含浸 '硬化させた紙等からなる摩擦材 1 5を、金属基材からなるコアプレート 1 4に接着することにより製造されること が多い。  The wet friction plate 12 is often manufactured by adhering a friction material 15 made of paper or the like impregnated and cured with a phenol resin to a core plate 14 made of a metal substrate.
メイティングプレート 1 3は、エンジンからの駆動力を伝達すると同時に摩擦 によって発生する熱を吸収する機能を担っており、 通常、 鋼板を環状に打抜いて 製造される。  The mating plate 13 has a function of transmitting driving force from the engine and absorbing heat generated by friction, and is usually manufactured by punching a steel plate in an annular shape.
このようなメイティングプレートの熱吸収能力を向上させるため、特開 2 0 0 2 - 5 4 6 5 3号公報は、 メイティングプレートに、 潤滑油の油溝を設けること を提案している。  In order to improve the heat absorption capability of such a mating plate, Japanese Patent Application Laid-Open No. 2000-0 5 46 65 3 proposes providing a lubricating oil groove in the mating plate.
この油溝の設け方としては、 メイティングプレート自体に径方向の貫通孔を設 けることと、表面に断面がコ字状の油溝を設けたメイティングプレートを油溝を 設けないメイティングプレートで覆って一組のメイティングプレートとするこ とにより、 径方向に貫通する孔を形成するものが開示されている。  The oil groove is provided by providing a through-hole in the radial direction in the mating plate itself, or a mating plate having an oil groove having a U-shaped cross section on the surface, and no oil groove. And a pair of mating plates are formed so as to form a hole penetrating in the radial direction.
発明の開示  Disclosure of the invention
しかし、 このような油溝の設け方であると、 薄板状の鋼板にその厚さの範囲内 で孔を開けたり、表面に断面がコ字状の油溝を切削加工したりしなければならな いため、 製造工程が複雑になり、 コストの上昇を招く問題があった。  However, with such an oil groove, it is necessary to make a hole in a thin steel plate within the thickness range, or to cut an oil groove having a U-shaped cross section on the surface. As a result, the manufacturing process becomes complicated, leading to an increase in cost.
そこで、 本発明は、 製造コストの上昇を来さないで、 径方向の油路を具えたメ ィティングプレートを提供することを目的とする。 本発明は、 Therefore, an object of the present invention is to provide a meeting plate having a radial oil passage without increasing the manufacturing cost. The present invention

The two intermediate plates have slits 開 く that open in the radial direction, alternately in the circumferential direction, and radially outward. A slit that opens in the direction is formed beyond the radial center position,

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
以下、 第 1図及至第 3図を参照して、 本発明の実施形態を説明する。 なお、 第 1図は、 本発明を適用した湿式摩擦係合装置の部分断面図、 第 2図はスリット入 り中間板の部分正面図、 第 3図は、 2枚のスリット入り中間板を位相合わせした ものの油路を透視して見た正面図である。  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 is a partial sectional view of a wet friction engagement device to which the present invention is applied, FIG. 2 is a partial front view of an intermediate plate with slits, and FIG. 3 is a phase diagram of two slit intermediate plates. It is the front view seen through the oil path of what was put together.
第 2図において、 スリット入り中間板 2 2には、 円周方向に見て互い違いに、 径方向内向きに開くスリット 2 3と径方向外向きに開くスリット 2 4が径方向 の中心位置を越えて形成されている。 この実施形態では、 径方向内向きに開くス リット 2 3と径方向外向きに開くスリツト 2 4は各 1 5個ずつ全部で 3 0個、 円 周方向に 1 2度おきに形成されている。但し、 これは一例に過ぎないことは言う までもない。  In FIG. 2, the slit intermediate plate 2 2 has a slit 2 3 that opens radially inward and a slit 2 4 that opens radially outward as seen in the circumferential direction, which exceeds the center position in the radial direction. Is formed. In this embodiment, the slits 2 3 opening inward in the radial direction and slits 2 4 opening outward in the radial direction are formed in a total of 30 pieces of 15 each, and every 12 degrees in the circumferential direction. . However, it goes without saying that this is only an example.
スプライン用の外歯 2 6は、 隣合うスリット 2 3 , 2 4に挟まれるように、 円 周方向に 1 2度おきに設けられている。 これも一例に過ぎないことは言うまでも ない。 The spline external teeth 2 6 are circled so that they are sandwiched between the adjacent slits 2 3 and 2 4. It is provided every 12 degrees in the circumferential direction. It goes without saying that this is only an example.
なお、 スプライン用の外歯 2 6は、 内歯 （図示せず。） となる場合もある。 このスリット入り中間板 2 2を 2枚重ねて、 内向きに開くスリット 2 3と外向 きに開くスリット 2 4が径方向に重なるように位相合わせをすると、第 3図に示 すように、 両スリッ卜の間に重複部分 2 5ができる。  The spline external teeth 26 may be internal teeth (not shown). When the two intermediate plates 2 2 with slits are stacked and phased so that the slits 2 3 that open inward and the slits 2 4 that open outwards overlap in the radial direction, as shown in FIG. Overlaps 25 are created between the slips.
2枚の中間板 2 2 , 2 2の外側に重ねる一対の外板 2 1， 2 1の正面図は示し ていないが、 その形状は、 スリット入り中間板 2 2からスリットをなくしたもの に相当する。  Although the front view of the pair of outer plates 2 1 and 2 1 that overlap the outside of the two intermediate plates 2 2 and 2 2 is not shown, the shape is equivalent to the slit-less intermediate plate 2 2 with no slits To do.
潤滑油は、遠心力により湿式摩擦係合装置 1 0 0の軸芯から径方向外側へ流れ るため、 まず、 潤滑油はスリット 2 3からメイティングプレート 2 0内に入り、 重複部分 2 5からスリット 2 4へと流れ、 外へ排出される。 このように、 潤滑油 は、 メイティングプレート 2 0内の油路を通ることから、 効率よく、 摩擦によつ て発生した熱を吸収 ·排出することが可能となる。  Since the lubricating oil flows radially outward from the axial center of the wet friction engagement device 100 by centrifugal force, first, the lubricating oil enters the mating plate 20 through the slit 23, and from the overlapping portion 25. It flows to slit 2 4 and is discharged outside. In this way, since the lubricating oil passes through the oil passage in the mating plate 20, it becomes possible to efficiently absorb and discharge heat generated by friction.
メイティングプレート 2 0は、 2枚のスリット入り中間板 2 2， 2 2をスリツ 卜の入っていない一対の外板 2 1， 2 1で挟むというサンドイッチ構造になって おり、 結局、 4枚の板で一単位のメイティングプレート 2 0を構成することにな る。 これらの 4枚の板は、 スプラインによって回転が阻止されているから、 ろう 付け等の方法により接合 ·一体化する必要はなく、 軸方向に自由に動いて差支え ない。  The mating plate 20 has a sandwich structure in which the two intermediate plates 2 2 and 2 2 with slits are sandwiched between a pair of outer plates 2 1 and 2 1 without slits. One unit of mating plate 20 is made up of plates. Since these four plates are prevented from rotating by the spline, they do not need to be joined and integrated by a method such as brazing, and may move freely in the axial direction.
なお、 外板 2 1， 2 1の数は、 一対 2枚に限ることはなく、 必要に応じて増や すことができる。 請求項 1において、 「4枚以上」 と記載したのは、 その趣旨で ある。  The number of outer plates 2 1 and 2 1 is not limited to a pair of two but can be increased as necessary. In Claim 1, “4 or more” is the purpose.
スリツト入り中間板 2 2は、 プレス打抜きの一回の工程で製造することができ、 切削加工の必要はない。 但し、 ばり取りのような後工程や、 平面出しのような標 準的工程は必要になることもある。  The slit-filled intermediate plate 22 can be manufactured in a single press punching process, and does not require cutting. However, post-processing such as deburring and standard processes such as leveling may be required.
以上説明したように、 本発明によれば、 製造コストの上昇を招くことなく、 熱 吸収効果の優れたメイティングプレートを得ることができる。  As described above, according to the present invention, a mating plate having an excellent heat absorption effect can be obtained without causing an increase in manufacturing cost.
産業上の利用可能性 本発明によれば、 孔開けや溝の切削というコス卜のかかる工程を必要とせず、 プレス打抜きによって、径方向の油路を具えたメイティングプレートを得ること ができるので、 低コストで、 熱吸収能力に優れたメイティングプレートを製造す ることができる。 Industrial applicability According to the present invention, it is possible to obtain a mating plate having a radial oil passage by press punching without requiring a costly process such as drilling or cutting a groove. A mating plate with excellent absorption capacity can be manufactured.
