Description

本発明は伝動用チェーンやベルトの弛みを防止するテンショナー装置であって、限られた小空間に取付け出来るように循環するチェーンやベルトの内側空間にテンショナーを配置したテンショナー装置に関するものである。   The present invention relates to a tensioner device that prevents slack of a transmission chain and a belt, and relates to a tensioner device in which a tensioner is disposed in an inner space of a circulating chain or belt so that it can be attached to a limited small space.

スプロケットに巻き掛けられて動力を伝達する場合、複数のリンクが繋がれて構成するチェーンは、各リンクの連結部が摩耗して伸びを発生する。自動二輪車用の後輪を駆動するように外に露出して巻き掛けられるローラチェーンであるならば、スプロケットの位置を調整することで伸びに対処することが出来るが、エンジン内部に使用されるタイミングチェーンのような場合には、テンショナーが取付けられていて、伸びに伴うチェーンのバタ付き及びバタ付きに伴う過張力を防止している。   When power is transmitted by being wound around a sprocket, a chain formed by connecting a plurality of links wears at a connecting portion of each link and generates elongation. If it is a roller chain that is exposed and wound around to drive the rear wheel of a motorcycle, it is possible to cope with the elongation by adjusting the position of the sprocket. In the case of a chain, a tensioner is attached to prevent the chain from being stretched due to elongation and the overtension associated with the butter.

図４は従来の一般的なテンショナーを示しているが、ハウジング(イ)と、該ハウジング(イ)にはプランジャー(ロ)が摺動可能に設けられ、外部から作動油(ハ)が油室(ニ)へ送り込まれることで、油室(ニ)に内蔵しているコイルバネ(ホ)を介して上記プランジャー(ロ)が突出する。従って、軸(ナ)を中心として揺動するテンショナレバー(ラ)を押し上げて弛んだチェーン(ヘ)には適度な張力が付与され、逆にチェーン(ヘ)に大きな張力が作用する際には、チェックバルブが閉じてプランジャー(ロ)の後退を阻止する。このようにチェーン(ヘ)は適度な張力が常に作用する状態に置かれる。   FIG. 4 shows a conventional general tensioner. A housing (A) and a plunger (B) are slidably provided in the housing (A), and hydraulic oil (C) is supplied from outside. By being fed into the chamber (d), the plunger (b) protrudes through a coil spring (e) built in the oil chamber (d). Therefore, a moderate tension is applied to the chain (f) slackened by pushing up the tensioner lever (ra) that swings about the shaft (na), and conversely when a large tension acts on the chain (f). The check valve closes to prevent the plunger (b) from moving backward. In this way, the chain (f) is placed in a state where a moderate tension is always applied.

ところで、上記テンショナーはスプロケットに巻き掛けられて循環する環状チェーンに囲まれた空間の外に配置されて突出するプランジャー(ロ)によってテンショナレバー(ラ)を押圧している。すなわち、テンショナーは一般に外置き形態として構成されているが、循環する環状チェーンの外に配置することでスペース的な問題が発生する。すなわち、スペース的にはチェーンで囲まれた内側に配置して、テンショナレバー(ラ)を内側へ引くような構造とする方が好都合となる。   By the way, the tensioner presses the tensioner lever (ra) by a plunger (b) that is disposed outside the space surrounded by the annular chain that wraps around the sprocket and circulates. In other words, the tensioner is generally configured as an external configuration, but a space problem occurs when the tensioner is arranged outside the circulating annular chain. That is, in terms of space, it is more convenient to arrange the tensioner lever (ra) inward by arranging it inside the chain.

ところで、従来のテンショナーにおいて、チェーンで囲まれた内側に配置した内置き型式のテンショナーとして、特開昭５７−１５９９０４号に係る「ＤＯＨＣ型内燃機関における動弁カム軸駆動用伝動帯の緊張装置」、特開昭５７−１４０９５３号に係る「伝動チェーンの緊張装置」、特開昭「内燃機関における動弁カム軸駆動用伝動帯の緊張装置」、実開昭５８−８９６３７号にかかる「無端回送体テンショナー機構」、特開平１０−３０６９４号に係る「液圧テンショナ装置」などが知られている。   By the way, in the conventional tensioner, as an in-place type tensioner arranged inside surrounded by a chain, “a tensioning device for a transmission valve shaft for driving a valve camshaft in a DOHC type internal combustion engine” according to Japanese Patent Laid-Open No. 57-159904 “Transmission chain tensioning device” according to Japanese Patent Laid-Open No. 57-140953, “Tensioning device of transmission band for driving valve shaft in internal combustion engine”, “Endless forwarding” according to Japanese Utility Model Laid-Open No. 58-89637 A “body tensioner mechanism”, a “hydraulic tensioner device” according to Japanese Patent Laid-Open No. 10-30694, and the like are known.

ところで、従来の内置き型テンショナー装置は、外置き型テンショナー装置に比較してスペース的な利点はあるが、テンショナーと環状チェーンの外側に配置されるテンショナレバーを繋ぐ作動レバーが必要と成る。従って、全体としての構造は複雑化し、その分重量は重くなる。そして、上記作動レバーはチェーンの両側に設ける場合と片側に設ける場合があり、片側作動レバーとする場合には力のアンバランスに基づく曲げモーメントが発生し、強度及び剛性を高くする必要がある。一方、チェーン両側に作動レバーを設ける場合には取付けが面倒となる。すなわち、エンジンブロック側の小さなスペースに作動レバーを配置しなくてはならない。
特開２００１−１８２７９０号に係る「内燃機関のチェーンテンショナ装置」 By the way, the conventional internal tensioner device has a space advantage as compared with the external tensioner device, but an operation lever that connects the tensioner and the tensioner lever arranged outside the annular chain is required. Therefore, the structure as a whole becomes complicated, and the weight increases accordingly. The actuating lever may be provided on both sides of the chain or on one side. When the actuating lever is provided on one side, a bending moment based on an unbalance of force is generated, and it is necessary to increase strength and rigidity. On the other hand, when operating levers are provided on both sides of the chain, the installation is troublesome. In other words, the operating lever must be arranged in a small space on the engine block side.
"Chain tensioner device for internal combustion engine" according to Japanese Patent Application Laid-Open No. 2001-182790

このように、従来の内置き型テンショナー装置には上記のごとき問題がある。本発明が解決しようとする課題はこれら問題点であり、チェーンの片側に作動レバーを容易に配置することが出来、しかも強度及び剛性の高い作動レバーを備えたテンショナー装置を提供する。   As described above, the conventional internal tensioner device has the above-described problems. The problem to be solved by the present invention is these problems, and provides a tensioner device in which an operating lever can be easily arranged on one side of a chain and has an operating lever with high strength and rigidity.

本発明に係る内置き型テンショナー装置は、作動レバーを介してテンショナレバーをチェーンに押圧する構造としている。作動レバーは概略「く」字形を成すと共にチェーンの片側に配置されて、テンショナレバーとテンショナーのプランジャーを連結している。すなわち、テンショナレバーに作動レバーの一方端が固定され、他方端はテンショナーのプランジャーと係合可能とし、プランジャーが突出することで作動レバーの係合部に当り、そしてテンションレバーが揺動してチェーンを緊張させることが出来る。上記作動レバーを構成する両アームの交差角は９０°以上の概略「く」形と成っている。   The internal tensioner device according to the present invention has a structure in which the tensioner lever is pressed against the chain via the operation lever. The actuating lever has a generally "<" shape and is disposed on one side of the chain to connect the tensioner lever and the plunger of the tensioner. That is, one end of the operating lever is fixed to the tensioner lever, the other end is engageable with the plunger of the tensioner, the plunger protrudes to hit the engaging portion of the operating lever, and the tension lever swings. Can tension the chain. The crossing angle of both arms constituting the actuating lever has a general “<” shape of 90 ° or more.

ここで、作動レバーとテンショナレバーとの接合部には弾性体パッドが使用されている為に衝撃が吸収され、接触部での打音が防止される。又、テンショナレバー及び作動レバーの揺動運動にてテンショナーのプランジャー先端との接触角度が変化する為に、作動レバーの他方端に取着している係合パットの係合面を滑らかな円弧面としている。さらに、作動レバーの形状は概略「く」形であるが、各アームの断面軸線を傾斜させて、変形と曲げ応力とを小さくすることにより、作動レバーの断面積を小さくし、軽量化を図っている。   Here, since an elastic pad is used at the joint between the actuating lever and the tensioner lever, the impact is absorbed and the hitting sound at the contact portion is prevented. In addition, since the contact angle with the tip of the tensioner plunger is changed by the swinging movement of the tensioner lever and the operating lever, the engaging surface of the engaging pad attached to the other end of the operating lever has a smooth circular arc. It is a surface. Furthermore, the shape of the actuating lever is roughly “<”, but the cross-sectional area of each arm is inclined to reduce deformation and bending stress, thereby reducing the cross-sectional area of the actuating lever and reducing the weight. ing.

本発明に係る内置き型テンショナー装置は、複数のスプロケットに巻き掛けられた環状チェーンの内側に取付けられるために、全体スペースの縮小を図ることが出来る。そして、環状チェーンの内側にあるテンショナーとテンショナレバーを連結する作動レバーは概略「く」形を成し、チェーンの片側に配置されることで、その取付けが簡単である。   Since the internal tensioner device according to the present invention is attached to the inside of an annular chain wound around a plurality of sprockets, the entire space can be reduced. The operation lever that connects the tensioner and the tensioner lever on the inner side of the annular chain has a generally "<" shape and is arranged on one side of the chain, so that the mounting thereof is easy.

又、作動レバーの一方端となるテンショナレバーとの接合部には弾性体パッドが取付けられている為に、衝撃力及び衝撃音の発生を防止でき、作動レバーの他方端に取着している係合パットは凸状円弧の係合面を形成している為に、テンショナレバーが揺動しても、テンショナーのプランジャー先端と係合して押圧力をチェーンに作用することが出来る。   In addition, since an elastic pad is attached to the joint with the tensioner lever that is one end of the operating lever, it is possible to prevent the generation of impact force and impact sound, and it is attached to the other end of the operating lever. Since the engagement pad forms a convex arcuate engagement surface, even if the tensioner lever swings, the engagement pad can engage with the tip of the plunger of the tensioner to apply a pressing force to the chain.

そして、概略「く」形の作動レバーは９０°以上の交差角を持った両アームを有し、アーム先端には弾性体パッドの取着部と係合パッドの係合部を垂直に屈曲して設けている。取着部の取付け面及び係合部の取付け面は各アームの断面主軸に対して傾斜していて、その為にアームの断面二次モーメントは大きくなり、発生する応力及び撓み変形は小さくなり、軽量化を図ることが出来る。以下、本発明に係る実施例を図面に基づいて詳細に説明する。   The generally "<" shaped actuating lever has both arms with an angle of 90 [deg.] Or more, and an elastic pad attaching part and an engaging pad engaging part are bent vertically at the arm tip. Provided. The attachment surface of the attachment portion and the attachment surface of the engagement portion are inclined with respect to the cross-section principal axis of each arm, and therefore the cross-sectional secondary moment of the arm is increased, and the generated stress and deformation are reduced. The weight can be reduced. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

図１はテンショナー９、及びテンショナレバー８を装着した本発明のテンショナー装置の実施例を表している。カム軸３ａ，３ｂを回転する為のスプロケット２ａ，２ｂ、オイルポンプ軸４を回転駆動するスプロケット５、クランク軸６に取着されているスプロケット７にはタイミングチェーン１は巻き掛けられ、そして、該タイミングチェーン１の伸びに基づく弛みを防止する為に、テンショナレバー８がアーム支軸１２を基点として揺動可能に取付けられている。   FIG. 1 shows an embodiment of a tensioner device of the present invention equipped with a tensioner 9 and a tensioner lever 8. The timing chain 1 is wound around the sprockets 2a and 2b for rotating the camshafts 3a and 3b, the sprocket 5 for rotationally driving the oil pump shaft 4, and the sprocket 7 attached to the crankshaft 6. In order to prevent loosening due to the elongation of the timing chain 1, the tensioner lever 8 is attached so as to be swingable around the arm support shaft 12.

該テンショナレバー８は弓形に湾曲していて、環状のタイミングチェーン１の外側に位置し、該タイミングチェーン１に押圧されて弛みが防止される。そして、上記各スプロケット２ａ，２ｂ，５，７に巻き掛けられているタイミングチェーン１の内側にはテンショナー９が取付けられ、該テンショナー９のプランジャー１０が突出することで、作動レバー１１を介してテンショナレバー８を揺動することが出来る。   The tensioner lever 8 is curved in an arcuate shape and is located outside the annular timing chain 1 and is pressed by the timing chain 1 to prevent loosening. A tensioner 9 is attached to the inside of the timing chain 1 wound around each of the sprockets 2a, 2b, 5 and 7, and the plunger 10 of the tensioner 9 protrudes, via the operation lever 11. The tensioner lever 8 can be swung.

上記作動レバー１１は概略「く」形を成し、その一端はテンショナレバー８の先端部にネジ止めにて取着されている。そして、他端はテンショナー９のプランジャー１０の先端が当るように係合可能とし、揺動しても係合するように湾曲面となっている。すなわち、テンショナレバー８はアーム支軸１２を中心として揺動し、同じく作動レバー１１もアーム支軸１２を中心に揺動する。プランジャー１０の先端は作動レバー１１が揺動した場合であっても、係合するように滑らかな凸状曲面を形成している。   The actuating lever 11 has a generally "<" shape, and one end thereof is attached to the tip of the tensioner lever 8 with screws. The other end can be engaged so that the tip of the plunger 10 of the tensioner 9 can be brought into contact, and has a curved surface so that it can be engaged even if it swings. That is, the tensioner lever 8 swings about the arm support shaft 12, and the operation lever 11 also swings about the arm support shaft 12. The tip of the plunger 10 forms a smooth convex curved surface so as to engage even when the operating lever 11 is swung.

図２は作動レバー１１を単独で表している。該作動レバー１１はその形状を概略「く」形とし、一方端には取着部１３が垂直に屈曲して形成され、他方端には係合部１４が垂直に屈曲して形成されている。取着部１３には２個の止ネジ穴１５ａ，１５ｂが貫通して設けられ、該取着部１３はテンショナレバー８に取付けられる弾性体パッド１６にネジ止めされる。すなわち、作動レバー１１はテンショナレバー８に弾性体パッド１６を介して取付けられる。   FIG. 2 shows the actuating lever 11 alone. The actuating lever 11 has a generally "<" shape, and is formed with a mounting portion 13 bent vertically at one end and an engaging portion 14 bent vertically at the other end. . Two fixing screw holes 15 a and 15 b are provided through the attachment portion 13, and the attachment portion 13 is screwed to an elastic pad 16 attached to the tensioner lever 8. That is, the operation lever 11 is attached to the tensioner lever 8 via the elastic pad 16.

そして、他方端の係合部１４には係合パッド１７が取付けられている。係合パッド１７は係合部１４に貫通した穴１８に嵌合すると共に、クリップリング１９にて止着される。図３(ａ)はテンショナレバー８に取付けられる弾性体パッド１６の具体例であり、２個のネジ穴２０ａ，２０ｂが設けられ、そしてテンショナレバー１１に係止する係止片２１ａ，２１ｂを有している。両係止片２１ａ，２１ｂを介して弾性体パッド１６はテンショナレバー８に係止して取付けられ、この弾性体パッド１６に設けているネジ穴２０ａ，２０ｂに作動レバー１１の取着部１３がネジ止めされる。   An engagement pad 17 is attached to the engagement portion 14 at the other end. The engagement pad 17 is fitted in a hole 18 penetrating the engagement portion 14 and is fixed by a clip ring 19. FIG. 3A is a specific example of the elastic pad 16 attached to the tensioner lever 8. Two screw holes 20 a and 20 b are provided, and locking pieces 21 a and 21 b that are locked to the tensioner lever 11 are provided. doing. The elastic pad 16 is fixedly attached to the tensioner lever 8 through both the locking pieces 21a and 21b, and the attachment portion 13 of the operating lever 11 is installed in the screw holes 20a and 20b provided in the elastic pad 16. Screwed.

図３(ｂ)は係合パッド１７を示す具体例であり、嵌合片２２が延びていて、先端部には溝２３を有している。そこで、嵌合片２２は作動レバー１１の他方端に設けた係合部１４の穴１８に嵌合し、外れないように溝２３にはクリップリング１９が嵌められる。そして、該係合パッド１７にはテンショナー９のプランジャー１０が突出して係合する為の係合面２４が形成されている。   FIG. 3B is a specific example showing the engagement pad 17, in which the fitting piece 22 extends and has a groove 23 at the tip. Therefore, the fitting piece 22 is fitted into the hole 18 of the engaging portion 14 provided at the other end of the operating lever 11, and the clip ring 19 is fitted into the groove 23 so as not to come off. The engagement pad 17 is formed with an engagement surface 24 for projecting and engaging the plunger 10 of the tensioner 9.

該係合面２４は滑らかな凸状面を成し、両側には縁２５ａ，２５ｂが突出して形成されている。該係合面２４にはテンショナー９のプランジャー１０が当って押圧され、係合部１４に作用する負荷Ｐはアーム支軸１２を基点とする時計方向のモーメントが発生し、テンショナレバー８は時計方向に揺動してタイミングチェーン１が弛まないように押圧する。   The engaging surface 24 forms a smooth convex surface, and edges 25a and 25b protrude from both sides. The plunger 10 of the tensioner 9 hits against the engaging surface 24 and is pressed, and the load P acting on the engaging portion 14 generates a moment in the clockwise direction with the arm support shaft 12 as a base point. The timing chain 1 is pressed so as not to loosen by swinging in the direction.

作動レバー１１はテンショナレバー８と共にアーム支軸１２を中心に揺動することでプランジャー先端との接触位置が変化するが、係合パッド１７の係合面２４は滑らかな凸状に湾曲している為、テンショナレバー１１の揺動位置に関わりなく係合する。   The operating lever 11 swings around the arm support shaft 12 together with the tensioner lever 8 to change the contact position with the plunger tip, but the engaging surface 24 of the engaging pad 17 is curved into a smooth convex shape. Therefore, the tensioner lever 11 is engaged regardless of the swinging position.

ところで、図１におけるＸ寸法＞Ｙ寸法と成っていて、テンショナーの反力が増大する比率を小さくしている。又、Ｒ2＜Ｒ1とすることで、テンショナーのプランジャー１０のストロークが小さくなり、該テンショナーは小型化される。 By the way, X dimension> Y dimension in FIG. 1 is satisfied, and the ratio at which the reaction force of the tensioner increases is reduced. Further, by satisfying R 2 <R 1 , the stroke of the plunger 10 of the tensioner is reduced, and the tensioner is miniaturized.

作動レバー１１は図２に示すように概略「く」形を成し、頂部から両方へ延びる２本のアーム２６ａ，２６ｂを有している。そして、該アーム２６ａの先端に取着部１３が垂直に屈曲して設けられ、アーム２６ｂの先端には係合部１４が垂直に屈曲して設けられている。そして取着部１３の取付け面２７に対してアーム２６ａの断面主軸は傾斜している。同じく、係合部１４の取付け面２７に対してアーム２６ｂの断面主軸は傾斜している。   As shown in FIG. 2, the actuating lever 11 has a generally "<" shape and has two arms 26a and 26b extending from the top to both sides. The attachment portion 13 is vertically bent at the tip of the arm 26a, and the engagement portion 14 is vertically bent at the tip of the arm 26b. The cross-sectional principal axis of the arm 26 a is inclined with respect to the mounting surface 27 of the attachment portion 13. Similarly, the cross-sectional principal axis of the arm 26b is inclined with respect to the mounting surface 27 of the engaging portion 14.

従って、両アーム２６ａ，２６ｂの交差角を９０°とすることで傾斜しない場合に比べてアームの断面二次モーメントは大きくなり、結果的に、発生する応力及び撓みは小さくなる。同じ応力であるならば、アーム断面を小さくして軽量化を図ることが可能となる。   Therefore, by setting the crossing angle between the arms 26a and 26b to 90 °, the secondary moment of section of the arm is increased as compared with the case where the arms are not inclined, and as a result, the generated stress and deflection are reduced. If the stresses are the same, the arm cross section can be reduced to reduce the weight.
