Description

本発明は、動力伝達装置に用いられるクラッチ又はブレーキの摩擦板用芯板又はメイティングプレートに関する。   The present invention relates to a core plate or mating plate for a friction plate of a clutch or brake used in a power transmission device.

動力伝達装置に用いられる摩擦板は、通常、環状の鋼板に摩擦材を接着したものであり、摩擦板のメイティングプレートは、通常、環状の鋼板からなる。
図１は、従来の湿式摩擦係合装置の軸方向断面図である。
図１において、湿式摩擦係合装置１は、ピストンＰがドラムＤ内の摩擦板３、メイティングプレート４を押圧した際、係合状態になって回転力を伝達し、また、ピストンＰが摩擦板３、メイティングプレート４から離れた際に解放状態になって回転力の伝達を断つようになっている（例えば、特許文献１参照。）。 A friction plate used in a power transmission device is usually a ring-shaped steel plate bonded with a friction material, and a mating plate of the friction plate is usually made of an annular steel plate.
FIG. 1 is an axial sectional view of a conventional wet friction engagement device.
In FIG. 1, when the piston P presses the friction plate 3 and the mating plate 4 in the drum D, the wet friction engagement device 1 enters an engaged state and transmits a rotational force. When the plate 3 and the mating plate 4 are separated from each other, they are in a released state to cut off the transmission of the rotational force (see, for example, Patent Document 1).

摩擦板３又はメイティングプレート４は、通常、鋼板を環状に打抜いたものである。
なお、一般に、厚さ３ｍｍ未満の鋼板を薄板、厚さ３ｍｍ以上６ｍｍ未満を中板、６ｍｍ以上を厚板と呼んでいる。 The friction plate 3 or the mating plate 4 is usually formed by punching a steel plate in an annular shape.
In general, a steel plate having a thickness of less than 3 mm is called a thin plate, a thickness of 3 mm or more and less than 6 mm is called a middle plate, and a thickness of 6 mm or more is called a thick plate.

摩擦板又はメイティングプレートには相手スプラインと噛合わせるための歯形が必要であるので、その製造方法としては、鋼板を環状に打抜き加工する際、歯形も同時にプレス打抜きするか、又は、鋼板を環状にプレス打抜きした後、歯形を切削加工して形成することになる。   Since the friction plate or mating plate requires a tooth profile for meshing with the mating spline, the manufacturing method is that when the steel plate is punched into a ring, the tooth profile is also stamped at the same time, or the steel plate is After press punching, the tooth profile is formed by cutting.

なお、摩擦板又はメイティングプレートではないが、複数の金属板を積層して、金属板の板厚よりも大きな厚みを有するようにしたトルク伝達部品の製造方法が、特許文献２に開示されている。
この特許文献２では、複数の金属板を積層した状態で、嵌合用の凸部と貫通孔（又は凹部）を嵌合させて一体化することにより、金属板自体の板厚よりも大きな厚みを有するトルク伝達部品を構成することができるとされている。 Although not a friction plate or mating plate, Patent Document 2 discloses a method for manufacturing a torque transmission component in which a plurality of metal plates are stacked to have a thickness larger than the plate thickness of the metal plates. Yes.
In this patent document 2, in the state which laminated | stacked the several metal plate, the thickness larger than the plate | board thickness of metal plate itself is obtained by fitting and integrating the convex part for fitting, and a through-hole (or recessed part). It is supposed that the torque transmission component which has can be comprised.

特許第３６５３２９５号公報Japanese Patent No. 36553295 特開平１０−１４１３８２号公報JP-A-10-141382

上述した鋼板をプレス打抜きして環状の摩擦板又はメイティングプレートを得る場合、素材である鋼板の材料利用率が最大でも３５％内外にしかならず、残りの材料が無駄になる。材料利用率を上げるために小径内部を再利用することが考えられるが、それは、材質、板厚等が必要とされる仕様に合致する場合に限られ、限定的となり、材料利用率を上げることは容易ではない。
また、大型の鋼板をプレス打抜きで得ようとすると、打抜き荷重の大きなプレス機を必要とし、設備投資が増すという問題があった。 When the above-described steel plate is press-punched to obtain an annular friction plate or mating plate, the material utilization rate of the steel plate as a raw material is only 35% at the maximum, and the remaining material is wasted. It is conceivable to reuse the inside of the small diameter in order to increase the material utilization rate, but this is limited to cases where the material, plate thickness, etc. meet the required specifications, and it will be limited and increase the material utilization rate. Is not easy.
In addition, when trying to obtain a large steel plate by press punching, a press machine having a large punching load is required, resulting in an increase in capital investment.

特許文献２のトルク伝達部品の製造方法では、金属板に設けられた嵌合用の凸部と貫通孔（又は凹部）を嵌合させる構成であるため、プレス打抜き以外の工程が増えるばかりでなく、積層された製品の表面には、必然的に、穴ができてしまう問題がある。   In the method of manufacturing the torque transmission component of Patent Document 2, since the fitting convex portion provided in the metal plate and the through hole (or concave portion) are fitted, not only the processes other than the press punching increase, There is a problem that holes are inevitably formed on the surface of the laminated product.

そこで、本発明は、前記課題を解決した、クラッチ又はブレーキの摩擦板用芯板又はメイティングプレートを提供することを目的とする。   Therefore, an object of the present invention is to provide a core plate or mating plate for a friction plate of a clutch or a brake that solves the above-mentioned problems.

本発明は、プレス打抜きされた複数枚の要素鋼板がろう付接合されたことを特徴とするクラッチ又はブレーキの摩擦板用芯板又はメイティングプレートにより、前記課題を解決した。   The present invention has solved the above problems by using a core plate or mating plate for a friction plate of a clutch or brake, wherein a plurality of press-punched element steel plates are brazed and joined.

本発明によれば、プレス打抜きされた複数枚の要素鋼板をろう付接合することによってクラッチ又はブレーキの摩擦板用芯板又はメイティングプレートを得ることができるので、強度面等においては従来と遜色がないものでありながら、大幅に製造コストを低減させることができる。   According to the present invention, a core plate or mating plate for a friction plate of a clutch or a brake can be obtained by brazing and joining a plurality of press-punched element steel plates. Although there is no such thing, the manufacturing cost can be greatly reduced.

以下、図２を参照して、本発明の第１実施形態を説明する。
図２は本発明の第１実施形態のクラッチ又はブレーキの摩擦板用芯板又はメイティングプレート（以下、単に「プレート」ということがある。）１０の斜視図である。 The first embodiment of the present invention will be described below with reference to FIG.
FIG. 2 is a perspective view of a friction plate core plate or mating plate (hereinafter simply referred to as “plate”) 10 of the clutch or brake of the first embodiment of the present invention.

図２において、プレート１０は、２数の要素鋼板１２がろう付け接合６０によって接合されたものである。
要素鋼板１２は、３枚以上にすることもある。 In FIG. 2, the plate 10 is obtained by joining two element steel plates 12 by brazing joint 60.
There may be three or more element steel plates 12.

本発明の第１実施形態のプレートの製造工程は次に説明する第２実施形態とほぼ同じであるから、そこで説明する。   The manufacturing process of the plate of the first embodiment of the present invention is almost the same as that of the second embodiment described below, and will be described there.

次に、本発明の第２実施形態を図３〜８を参照して説明する。
図３は本発明の第２実施形態のクラッチ又はブレーキの摩擦板用芯板又はメイティングプレート１００の斜視図である。 Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 3 is a perspective view of the friction plate core plate or mating plate 100 of the clutch or brake according to the second embodiment of the present invention.

図４はプレス打抜き工程におけるセグメント２０，３０を示す図で、図５が、これらのセグメント２０，３０を、環状をなすように組合せた状態を示す斜視図である。   FIG. 4 is a diagram showing the segments 20 and 30 in the press punching process, and FIG. 5 is a perspective view showing a state in which these segments 20 and 30 are combined so as to form an annular shape.

図３においても、プレート１００は、２枚の要素鋼板１２０がろう付け接合６０によって接合されてなる。
まず、図４に示すように、板状鋼板素材Ｍから、内歯歯形を有するセグメント２０，３０をプレス打抜きする。 Also in FIG. 3, the plate 100 is formed by joining two element steel plates 120 by brazing joint 60.
First, as shown in FIG. 4, the segments 20 and 30 having an internal tooth profile are press-punched from the plate-shaped steel plate material M.

この例では、セグメント２０，３０は、要素鋼板１２０が周方向に４分割された形状である。なお、周方向に分割する数は複数枚であるが、接合部において、だれ面とばり面を組合せるために、偶数が好ましい。
打抜き加工によって得られたセグメント２０，３０は、図５に示すように、環状に組合されて一枚の要素鋼板１２０となる。
なお、歯形は、要素鋼板１２０の内周にある場合と、外周にある場合とがあり、歯形の底の弧状のほぼ中央で組合されるようにする。 In this example, the segments 20 and 30 have a shape in which the element steel plate 120 is divided into four in the circumferential direction. In addition, although the number divided | segmented into the circumferential direction is multiple pieces, in order to combine a bevel surface and a flash surface in a junction part, an even number is preferable.
As shown in FIG. 5, the segments 20 and 30 obtained by the punching process are combined into an annular shape to form one elemental steel plate 120.
Note that the tooth profile may be on the inner periphery or the outer periphery of the element steel plate 120, and is combined at the substantially arcuate center of the bottom of the tooth profile.

セグメント２０，３０の両端には、隣合うセグメントの結合度を高めるためにジグソーパズルにあるような雌形継手部２２，３２と雄形継手部２４，３４をそれぞれ形成する。
なお、図４にあるように、雌形継手部２２，３２と雄形継手部２４，３４が互い違いの関係になるように配置するのは、後で説明するように、図７に示すように、継手部の雄形と雌形の結合度を高めるために打抜いたセグメントの表裏を逆にするので、その際、雄形と雌形が自動的に隣合うようにするためである。 Female joint portions 22 and 32 and male joint portions 24 and 34 as in a jigsaw puzzle are formed at both ends of the segments 20 and 30, respectively, in order to increase the degree of coupling between adjacent segments.
As shown in FIG. 7, as will be described later, the female joint portions 22, 32 and the male joint portions 24, 34 are arranged in an alternating relationship as shown in FIG. This is because the front and back of the punched segments are reversed in order to increase the degree of coupling between the male and female joints, so that the male and female shapes are automatically adjacent to each other.

プレス打抜きされたセグメント２０，３０は、図５のように、雌形継手部２２，３２と雄形継手部２４，３４が、ジグソーパズルのように互いに嵌合されて一枚の要素板１２０にされる。   As shown in FIG. 5, the press punched segments 20 and 30 are formed into a single element plate 120 by fitting female joint portions 22 and 32 and male joint portions 24 and 34 together like a jigsaw puzzle. The

次に、積層工程において、図６に示す組合せ治具５０が使用される。下板５６には、外側位置出しジグ５２と内側歯合わせジグ５４が４組設置されている。   Next, in the stacking step, a combination jig 50 shown in FIG. 6 is used. The lower plate 56 is provided with four sets of an outer positioning jig 52 and an inner tooth alignment jig 54.

なお、一般的に、プレスによる打抜き加工においては、パンチと金型との間に或る隙間が設定されるため、打抜かれた板には、上側に「だれ」が、下側に「ばり」が形成され、上側のほうが、若干、側面方向に出っ張った断面形状になることが避けられない。
そこで、セグメント２０，３０を環状に組合せる際、図７に示すように、プレス打抜き時に発生するだれＤが隣合うセグメント２０，３０で対向しないように、表裏を逆にして組合せるものとする。こうすることによって、セグメント２０，３０間の隙間を小さくし、結合度を高めることができる。 In general, in a punching process using a press, a certain gap is set between the punch and the die, so that the “cut” is on the upper side and the “burr” is on the lower side of the punched plate. It is inevitable that the upper portion has a slightly cross-sectional shape protruding in the side surface direction.
Therefore, when the segments 20 and 30 are combined in an annular shape, as shown in FIG. 7, the front and back are combined so that nobody D generated during press punching is opposed to the adjacent segments 20 and 30. . By doing so, the gap between the segments 20 and 30 can be reduced and the degree of coupling can be increased.

以上のようにして構成された図５の要素鋼板１２０を図６の最下部に配置し、ドーナツ形で箔状の、又は粉状のろう材（図示せず。）をその上に載せ、その上に、さらに、もう一組の要素鋼板１２０を重ねる。
要素鋼板１２０を３枚使用する場合は、上記のように、ろう材を載せ、その上に、さらに、もう一組の要素鋼板１２０を載せる作業を繰返す。 The element steel plate 120 of FIG. 5 configured as described above is placed at the bottom of FIG. 6, and a doughnut-shaped, foil-like or powdery brazing material (not shown) is placed thereon, Further, another set of element steel plates 120 is further stacked.
When three elemental steel plates 120 are used, as described above, the operation of placing the brazing material and placing another set of elemental steel plates 120 thereon is repeated.

なお、環状に組合された要素鋼板１２０を積層する際は、上下に隣合う要素鋼板１２０のセグメント２０，３０が連結された部分の位相を各要素鋼板１２０毎にずらす。   In addition, when laminating | stacking the element steel plate 120 combined in cyclic | annular form, the phase of the part where the segments 20 and 30 of the element steel plate 120 adjacent to the upper and lower sides was connected is shifted for every element steel plate 120. FIG.

以上の工程を所定の回数繰返し、所定の枚数を重ねた後、内側歯合わせジグ５４により、積層された要素鋼板１２０間の歯のずれを補正する。   The above steps are repeated a predetermined number of times, and after a predetermined number of sheets are stacked, the tooth misalignment between the laminated element steel plates 120 is corrected by the inner tooth alignment jig 54.

その後、図８に示すように、組合せ治具５０の下板５６に対して、上板５８をスタッドボルトＢとナットＮによって締付ける。なお、好ましくは、ナットＮと上板５８の間に、耐熱性の皿ばね等の弾性体５９を配する。   Thereafter, as shown in FIG. 8, the upper plate 58 is tightened with the stud bolt B and the nut N against the lower plate 56 of the combination jig 50. Preferably, an elastic body 59 such as a heat-resistant disc spring is disposed between the nut N and the upper plate 58.

次に、熱処理工程において、積層された要素鋼板１２０とろう材のセットを加熱炉（図示せず。）に投入し、ろう材が溶融する温度域で加熱する（プレステンパ）。
なお、加熱炉に同時に投入される要素鋼板１２０の数量は、加熱炉の内部容積に応じて適宜に定めることができる。また、要素鋼板１２０は、外側位置出しジグ５２と内側歯合わせジグ５４を設置したまま加熱炉に投入することもできるが、好ましくは、これらのジグは外してから加熱炉に投入する。 Next, in the heat treatment step, the set of the laminated element steel plates 120 and the brazing material is put into a heating furnace (not shown) and heated in a temperature range where the brazing material melts (press tempering).
In addition, the quantity of the element steel plates 120 thrown into a heating furnace simultaneously can be determined suitably according to the internal volume of a heating furnace. The element steel plate 120 can also be put into the heating furnace with the outer positioning jig 52 and the inner toothing jig 54 installed, but preferably, these jigs are put into the heating furnace after being removed.

その後、適切な保持時間・冷却時間を経ることにより、図３のように完成されたプレート１００を得ることができる。その後、ギヤシェーパで歯形の仕上げ加工を施す。   Thereafter, the plate 100 completed as shown in FIG. 3 can be obtained through appropriate holding time and cooling time. Thereafter, the tooth shape is finished with a gear shaper.
