Description

本発明は、捩り振動低減装置に関し、スペーサの半径方向の摩耗は促進される一方、軸方向の摩耗は促進されないようにしたものである。   The present invention relates to a device for reducing torsional vibrations, wherein the radial wear of the spacer is promoted while the axial wear is not promoted.

自動車には自動変速機を用いるものがあり、該自動変速機にエンジンのトルク変動に起因した捩り振動が伝達されるのを防止するため、捩り振動低減装置が用いられる。   Some automobiles use an automatic transmission, and a torsional vibration reducing device is used to prevent the torsional vibration caused by torque fluctuations of the engine from being transmitted to the automatic transmission.

従来の捩り振動低減装置としては、例えば特許文献1に記載のものが知られている。エンジンのクランクシャフトに一対の入力部材(ドライブプレートおよびサイドプレート)の内周部がボルトを介して結合され、該一対の入力部材の間に回転自在に設けられた出力部材(ドリブンプレート)の外周部がトルクコンバータのコンバータカバーに結合され、一対の入力部材と出力部材とは圧縮ばねにより円周方向に連結されている。   As a conventional torsional vibration reduction device, for example, a device described in Patent Document 1 is known. The inner periphery of a pair of input members (drive plate and side plate) is coupled to the crankshaft of the engine via bolts, and the outer periphery of an output member (driven plate) that is rotatably provided between the pair of input members The part is coupled to the converter cover of the torque converter, and the pair of input member and output member are coupled in the circumferential direction by a compression spring.

一対の入力部材と出力部材とは一対の入力部材の間に配置された軸受を介してセンタリングされ、コンバータカバーと一体に設けられたパイロットボスとクランクシャフトとがパイロットブッシュを介してセンタリングされている。つまり、軸受とパイロットブッシュとは剛性が小さく摩耗し易い樹脂材により構成されているので、これらが摩耗することにより、入力部材と出力部材との軸心が僅かにずれていても、この軸心のずれが吸収される。
特開平08−28628号公報
The pair of input members and the output member are centered via a bearing disposed between the pair of input members, and a pilot boss and a crankshaft provided integrally with the converter cover are centered via a pilot bush. . In other words, since the bearing and the pilot bush are made of a resin material having a small rigidity and easy to wear, even if the shaft centers of the input member and the output member are slightly shifted due to wear, the shaft center is formed. The deviation is absorbed.
Japanese Patent Laid-Open No. 08-28628

ところが、前記軸受と前記パイロットブッシュとを、軸受としてだけではなく、軸方向の樹脂スペーサとして軸方向での部品と部品との位置決めとして機能させようとすると、前記軸受と前記パイロットブッシュとは摩耗し易い樹脂材により構成されているので、摩耗により位置決めの機能が果たせなくなるという課題がある。   However, if the bearing and the pilot bush are to function not only as a bearing but also as an axial resin spacer for positioning parts in the axial direction, the bearing and the pilot bushing are worn. Since it is comprised with the easy resin material, there exists a subject that the function of positioning cannot be performed by abrasion.

また、凹凸状の高面圧接触部としてのセレーション部分では、突起部が摩耗するにつれて摺動面積が増えて面圧が下がっていくため、摩耗速度が途中で遅くなり、所定の時間内に所定量の摩耗が実行されないという課題がある。   In addition, in the serration portion as an uneven high surface pressure contact portion, the sliding area increases and the surface pressure decreases as the projection portion wears, so the wear speed decreases in the middle, and within a predetermined time. There is a problem that a fixed amount of wear is not performed.

そこで本発明は、上記の課題を解決し、樹脂スペーサが径方向で摩耗が促進される一方、軸方向では摩耗が促進されない捩り振動低減装置を提供することを目的とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-described problems and provide a torsional vibration reduction device in which wear of a resin spacer is accelerated in the radial direction but wear is not promoted in the axial direction.

請求項1に係る発明は、クランクシャフトに連結された入力部材と、該入力部材の軸方向隣に該入力部材によりセンタリングされて設けられると共にトランスミッションの入力軸に連結された出力部材と、該出力部材と前記入力部材とを円周方向に連結する弾性部材とを備えた捩り振動低減装置において、
前記出力部材の半径方向内周側に、前記入力部材へ向かって軸方向へ突出して外周面を形成する外周面形成部が形成され、前記出力部材と前記入力部材との軸方向間にスペーサが介装され、該スペーサには、軸方向へ突出する筒部が形成され、該筒部が前記出力部材の前記外周面形成部と前記入力部材の内周面との間に介装され、
あるいは、前記出力部材の半径方向外周側に、前記入力部材へ向かって軸方向へ突出して内周面を形成する内周面形成部が形成され、前記出力部材と前記入力部材との軸方向間にスペーサが介装され、該スペーサには、軸方向へ突出する筒部が形成され、該筒部が前記入力部材の外周面と前記出力部材の前記内周面形成部との間に介装され、
該筒部の内周面と外周面とのうちの前記入力部材または前記出力部材と摺動する面には、摺動により摩耗する摩耗部が形成されていることを特徴とする。
The invention according to claim 1 includes an input member connected to the crankshaft, an output member connected to the input shaft of the transmission and provided in the axial direction next to the input member and centered by the input member, and the output In the torsional vibration reduction device comprising a member and an elastic member that connects the input member in the circumferential direction,
An outer peripheral surface forming portion that protrudes in the axial direction toward the input member and forms an outer peripheral surface is formed on the radially inner peripheral side of the output member, and a spacer is provided between the output member and the input member in the axial direction. A cylindrical portion protruding in the axial direction is formed on the spacer, and the cylindrical portion is interposed between the outer peripheral surface forming portion of the output member and the inner peripheral surface of the input member,
Alternatively, an inner peripheral surface forming portion that protrudes in the axial direction toward the input member to form an inner peripheral surface is formed on the outer peripheral side in the radial direction of the output member, and between the axial direction of the output member and the input member A spacer is formed on the spacer, and a cylindrical portion protruding in the axial direction is formed on the spacer, and the cylindrical portion is interposed between the outer peripheral surface of the input member and the inner peripheral surface forming portion of the output member. And
Of the inner peripheral surface and the outer peripheral surface of the tubular portion, a surface that slides with the input member or the output member is formed with a wear portion that is worn by sliding.

この発明によれば、スペーサは、相対的に回転する入力部材と出力部材との軸方向間に存在し、軸方向での摩耗は少ない。一方、半径方向では、スペーサの筒部が、出力部材の外周面形成部と入力部材の内周面との間または入力部材の外周面と出力部材の内周面形成部との間に介装されており、筒部の内周面と外周面とのうちの入力部材または出力部材と摺動する面には、摺動により摩耗する摩耗部が形成されているので、半径方向での摩耗は促進される。従って、摩耗を促進させて軸心のズレを吸収したい入力部材と出力部材とのセンタリングと、摩耗を促進させることなく入力部材と出力部材との軸方向の位置関係を変えたくない軸方向での位置決めとの相反する作用が行われる。   According to this invention, the spacer exists between the axial direction of the relatively rotating input member and output member, and wear in the axial direction is small. On the other hand, in the radial direction, the cylindrical portion of the spacer is interposed between the outer peripheral surface forming portion of the output member and the inner peripheral surface of the input member, or between the outer peripheral surface of the input member and the inner peripheral surface forming portion of the output member. Since the wear part which wears by sliding is formed in the surface which slides with the input member or the output member of the inner peripheral surface and the outer peripheral surface of the cylindrical part, the wear in the radial direction is Promoted. Therefore, the centering between the input member and the output member that wants to promote wear and absorb the axial misalignment, and the axial position between the input member and the output member that do not want to change without promoting the wear in the axial direction. Opposition to positioning is performed.

請求項2に係る発明は、請求項1に記載の捩り振動低減装置において、前記摩耗部は、前記入力部材または前記出力部材と摺動する摺動部が円周方向へ間欠的に複数形成され面圧が高く構成されていることを特徴とする。   According to a second aspect of the present invention, in the torsional vibration reduction device according to the first aspect, the wear portion includes a plurality of sliding portions that slide with the input member or the output member intermittently in a circumferential direction. It is characterized by a high surface pressure.

この発明によれば、スペーサの筒部の内周面と外周面とのうちの入力部材または出力部材と摺動する面に、複数の摺動部を円周方向へ間欠的に形成し、出力部材または入力部材と摺動する部分の面圧を高くして摩耗部を形成したので、摩耗部の摩耗が促進される。従って、入力部材と出力部材との軸心が僅かにずれていても、軸心のズレを吸収できる。   According to this invention, a plurality of sliding portions are intermittently formed in the circumferential direction on the surface that slides with the input member or the output member of the inner peripheral surface and the outer peripheral surface of the cylindrical portion of the spacer, and the output Since the wear portion is formed by increasing the surface pressure of the portion sliding with the member or the input member, wear of the wear portion is promoted. Therefore, even if the axial center of the input member and the output member is slightly shifted, the shift of the axial center can be absorbed.

請求項3に係る発明は、請求項2に記載の捩り振動低減装置において、前記摺動部は前記筒部の内周面と外周面とに、円周方向に沿って交互に形成されていることを特徴とする。   According to a third aspect of the present invention, in the torsional vibration reducing device according to the second aspect, the sliding portions are alternately formed on the inner peripheral surface and the outer peripheral surface of the cylindrical portion along the circumferential direction. It is characterized by that.

この発明によれば、筒部の内周面と外周面とに円周方向に沿って交互に摺動部を形成したので、スペーサの筒部が半径方向へ撓み易く弾性の性質を有するに至る。従って、スペーサの筒部の摩耗による軸心のズレの吸収に加えて撓みによる軸心のズレの吸収が加わり、軸心のズレの吸収機能が一段と高くなる。なお、筒部の内周面と外周面とに形成される摺動部の一方が入力部材または出力部材に対して摺動しない場合は、当接部となる。   According to the present invention, since the sliding portions are alternately formed along the circumferential direction on the inner peripheral surface and the outer peripheral surface of the cylindrical portion, the cylindrical portion of the spacer is easily bent in the radial direction and has an elastic property. . Therefore, in addition to absorbing the shift of the shaft center due to wear of the cylindrical portion of the spacer, the absorption of the shift of the shaft center due to bending is added, and the function of absorbing the shift of the shaft center is further enhanced. In addition, when one of the sliding parts formed in the inner peripheral surface and outer peripheral surface of a cylinder part does not slide with respect to an input member or an output member, it becomes a contact part.

請求項4に係る発明は、請求項1〜3のいずれかに記載の捩り振動低減装置において、前記入力部材と前記出力部材とのいずれか一方が一対の側板により構成され、他方が該一対の側板の軸方向間に挟まれて相対回転自在な中央板により構成され、前記一対の側板と前記中央板との軸方向間に一対の前記スペーサが介装され、該一対のスペーサの少なくともいずれか一方に、前記筒部が形成されていることを特徴とする。   The invention according to claim 4 is the torsional vibration reduction device according to any one of claims 1 to 3, wherein either the input member or the output member is constituted by a pair of side plates, and the other is the pair of side plates. A center plate sandwiched between axial directions of side plates and relatively rotatable, and a pair of spacers is interposed between the pair of side plates and the central plate in the axial direction, and at least one of the pair of spacers On the other hand, the cylindrical portion is formed.

この発明によれば、入力部材と出力部材とのいずれかが一対の側板によって構成されているので、入力部材と出力部材との軸方向間に配置されるスペーサも一対となる。   According to the present invention, since either the input member or the output member is constituted by a pair of side plates, the spacers disposed between the input member and the output member in the axial direction are also a pair.

請求項1に係る発明によれば、スペーサの筒部の内周面と外周面とのうちの入力部材または出力部材と摺動する面には、摺動により摩耗する摩耗部が形成されているので、半径方向での摩耗は促進される。従って、摩耗を促進させて軸心のズレを吸収したい入力部材と出力部材とのセンタリングと、摩耗を促進させることなく入力部材と出力部材との軸方向の位置関係を変えたくない軸方向での位置決めとの相反する作用を行わせることができる。   According to the invention which concerns on Claim 1, the wear part which wears by sliding is formed in the surface which slides with the input member or the output member of the inner peripheral surface and outer peripheral surface of the cylinder part of a spacer. Therefore, wear in the radial direction is promoted. Therefore, the centering between the input member and the output member that wants to promote wear and absorb the axial misalignment, and the axial position between the input member and the output member that do not want to change without promoting the wear in the axial direction. It is possible to perform an operation opposite to the positioning.

請求項2に係る発明によれば、複数の摺動部を円周方向へ間欠的に形成し、出力部材または入力部材と摺動する部分の面圧を高くして、スペーサの筒部の内周面または外周面に摩耗部を形成したので、摩耗部の摩耗が促進される。従って、入力部材と出力部材との軸心が僅かにずれていても、軸心のズレを吸収できる。   According to the invention of claim 2, a plurality of sliding portions are intermittently formed in the circumferential direction, the surface pressure of the portion sliding with the output member or the input member is increased, and the inside of the cylindrical portion of the spacer Since the wear portion is formed on the peripheral surface or the outer peripheral surface, wear of the wear portion is promoted. Therefore, even if the axial center of the input member and the output member is slightly shifted, the shift of the axial center can be absorbed.

請求項3に係る発明によれば、筒部の内周面と外周面とに円周方向に沿って交互に摺動部を形成したので、スペーサの筒部が半径方向へ撓み易く弾性の性質を有するに至る。従って、スペーサの筒部の摩耗による軸心のズレの吸収に加えて撓みによる軸心のズレの吸収が加わり、軸心のズレの吸収機能が一段と高くなる。   According to the invention of claim 3, since the sliding portions are alternately formed along the circumferential direction on the inner peripheral surface and the outer peripheral surface of the cylindrical portion, the cylindrical portion of the spacer is easily bent in the radial direction and has an elastic property. To have. Therefore, in addition to absorbing the shift of the shaft center due to wear of the cylindrical portion of the spacer, the absorption of the shift of the shaft center due to bending is added, and the function of absorbing the shift of the shaft center is further enhanced.

請求項4に係る発明によれば、入力部材と出力部材とのいずれかが一対の側板によって構成されているので、入力部材と出力部材との軸方向間に配置されるスペーサも一対となる。   According to the fourth aspect of the present invention, since either the input member or the output member is constituted by a pair of side plates, the spacers disposed between the input member and the output member in the axial direction are also a pair.

The parts are connected via a rivet 4. On the other hand, a driven plate 5 is provided as a central plate which is an output member, and the driven plate 5 is disposed between the drive plate 2 and the side plate 3 so as to be relatively rotatable. The driven plate 5 is connected to an input shaft of a transmission (not shown) via an output hub 6 disposed inside the driven plate 5. The driven plate 5 and the output hub 6 are coupled via a plurality of rivets 7.

ドライブプレート2,サイドプレート3とドリブンプレート5とは、弾性部材としてのばね8を介して円周方向に連結されている。即ち、以下のように構成されている。ドライブプレート2,サイドプレート3には円周方向に沿って4つの窓2a,3aが夫々形成され、該窓2a,3aどうしの間に位置する部分には、ばね受け部2b,3bが夫々形成されている。一方、ドリブンプレート5の円周方向でのばね受け部2b,3bと対応する位置には、半径方向外側へ突出するばね受け部5bが形成され、これにより該ばね受け部5bどうしの間に切欠部5aが形成されている。そして、窓2a,窓3a,切欠部5aの部分には一対のばね8が収容されている。   The drive plate 2, the side plate 3, and the driven plate 5 are connected in the circumferential direction via springs 8 as elastic members. That is, it is configured as follows. Four windows 2a and 3a are respectively formed in the drive plate 2 and the side plate 3 along the circumferential direction, and spring receiving portions 2b and 3b are respectively formed in portions located between the windows 2a and 3a. Has been. On the other hand, a spring receiving portion 5b protruding outward in the radial direction is formed at a position corresponding to the spring receiving portions 2b and 3b in the circumferential direction of the driven plate 5, and thereby a notch is formed between the spring receiving portions 5b. Part 5a is formed. A pair of springs 8 is accommodated in the window 2a, the window 3a, and the notch 5a.

該一対のばね8の夫々は、外径寸法の大きな親ばね8aと外径寸法の小さな子ばね8bとから構成されており、親ばね8aの内部に子ばね8bが収容されている。一対のばね8は、フローティングイコライザ9を介して円周方向へ連結されている。該フローティングイコライザ9は、リング状の環状部9aと、該環状部9aから半径方向内側へ突出する連結部9bとにより構成され、該連結部9bが一対のばね8の間に介装されている。   Each of the pair of springs 8 includes a parent spring 8a having a large outer diameter and a child spring 8b having a small outer diameter, and the child spring 8b is accommodated inside the parent spring 8a. The pair of springs 8 are connected in the circumferential direction via a floating equalizer 9. The floating equalizer 9 includes a ring-shaped annular portion 9 a and a connecting portion 9 b that protrudes radially inward from the annular portion 9 a. The connecting portion 9 b is interposed between a pair of springs 8. .

前記ドライブプレート2と前記ドリブンプレート5との間と、サイドプレート3と前記ドリブンプレート5との間には、樹脂スペーサ10が夫々介装されている。該樹脂スペーサ10の形状を図3に示す。該樹脂スペーサ10は板状材を円弧状に繰り抜いた形状のフランジ部10aと、該フランジ部10aの内周側から軸方向へ突出する筒部10bとにより構成されている。該筒部10bの内周面には、摺動により摩耗する摩耗部が形成されている。該摩耗部は、後述する外周面6aと摺動する摺動面10cを有する摺動部10dを、円周方向へ間欠的に複数形成して外周面6aとの面圧を高くしたものである。   Resin spacers 10 are interposed between the drive plate 2 and the driven plate 5 and between the side plate 3 and the driven plate 5, respectively. The shape of the resin spacer 10 is shown in FIG. The resin spacer 10 includes a flange portion 10a having a shape in which a plate-like material is drawn out in an arc shape, and a cylindrical portion 10b protruding in the axial direction from the inner peripheral side of the flange portion 10a. A wear portion that is worn by sliding is formed on the inner peripheral surface of the cylindrical portion 10b. The wear portion is formed by intermittently forming a plurality of sliding portions 10d having a sliding surface 10c that slides with an outer peripheral surface 6a, which will be described later, in the circumferential direction to increase the surface pressure with the outer peripheral surface 6a. .

次に、前記ドリブンプレート5の半径方向内周側に結合した前記出力ハブ6が、前記ドリブンプレート5の軸方向へ突出する外周面形成部として機能する。そして、出力ハブ6の外周面6aと前記サイドプレート3の内周面3cとの間に、前記一対の樹脂スペーサ10の一方の筒部10bが介装されている。前記一対の樹脂スペーサ10をドライブプレート2,サイドプレート3と一体回転させるため、以下のように構成されている。ドライブプレート2,サイドプレート3には円周方向に沿って4つの孔が形成される一方、樹脂スペーサ10のフランジ部10aの外周部には、外周側から4つの切欠部10eが形成され、該切欠部10eと前記4つの孔にストッパボルト11が挿通され、該ストッパボルト11の両端がかしめられている。ストッパボルト11がドリブンプレート5と干渉するのを回避するため、図2(a)に示すように、ストッパボルト11はドリブンプレート5の外周部に形成された前記切欠部5aの内周側に位置している。   Next, the output hub 6 coupled to the radially inner peripheral side of the driven plate 5 functions as an outer peripheral surface forming portion protruding in the axial direction of the driven plate 5. Between the outer peripheral surface 6 a of the output hub 6 and the inner peripheral surface 3 c of the side plate 3, one cylindrical portion 10 b of the pair of resin spacers 10 is interposed. In order to integrally rotate the pair of resin spacers 10 with the drive plate 2 and the side plate 3, the following configuration is provided. While the drive plate 2 and the side plate 3 are formed with four holes along the circumferential direction, the outer peripheral portion of the flange portion 10a of the resin spacer 10 is formed with four notches 10e from the outer peripheral side, Stopper bolts 11 are inserted through the notches 10e and the four holes, and both ends of the stopper bolts 11 are caulked. In order to avoid the stopper bolt 11 from interfering with the driven plate 5, the stopper bolt 11 is positioned on the inner peripheral side of the notch 5 a formed on the outer peripheral portion of the driven plate 5 as shown in FIG. is doing.

この実施の形態では、樹脂スペーサ10がドライブプレート2,サイドプレート3と一体回転するため、筒部10bの内周面が出力ハブ6の外周面6aと摺動する面となり、内周面には摩耗部が形成されている。該摩耗部は、図3(a)に示すように、出力ハブ6の外周面6aに摺動する摺動面10cを有する摺動部10dを、円周方向へ間欠的に複数形成して構成されている。摺動部10dを円周方向に沿って間欠的に形成することにより、出力ハブ6の外周面6aとの面圧を高くし、摺動部10dの摩耗が促進されるようにしたものである。
(作用)
次に、捩り振動低減装置の作用を説明する。
In this embodiment, since the resin spacer 10 rotates integrally with the drive plate 2 and the side plate 3, the inner peripheral surface of the cylindrical portion 10 b becomes a surface that slides with the outer peripheral surface 6 a of the output hub 6. A wear part is formed. As shown in FIG. 3A, the wear portion is formed by intermittently forming a plurality of sliding portions 10d having a sliding surface 10c that slides on the outer peripheral surface 6a of the output hub 6 in the circumferential direction. Has been. By forming the sliding portion 10d intermittently along the circumferential direction, the surface pressure with the outer peripheral surface 6a of the output hub 6 is increased, and the wear of the sliding portion 10d is promoted. .
(Function)
Next, the operation of the torsional vibration reducing device will be described.

エンジンの回転がクランク軸とフライホィールマス1とを介してドライブプレート2,サイドプレート3へ伝わり、ドライブプレート2,サイドプレート3からばね8を介してドリブンプレート5へ伝わる。そして、ドリブンプレート5から出力ハブ6を介して図示しないトルクコンバータのコンバータカバーへ伝わる。ばね8が圧縮されることにより、ドライブプレート2,サイドプレート3とドリブンプレート5との間で相対回転が可能なので、捩り振動が低減される。   The rotation of the engine is transmitted to the drive plate 2 and the side plate 3 through the crankshaft and the flywheel mass 1, and is transmitted from the drive plate 2 and the side plate 3 to the driven plate 5 through the spring 8. Then, it is transmitted from the driven plate 5 to the converter cover of the torque converter (not shown) via the output hub 6. Since the spring 8 is compressed, relative rotation is possible between the drive plate 2, the side plate 3 and the driven plate 5, so that torsional vibration is reduced.

図1に示すように、ドリブンプレート5とドライブプレート2との間と、ドリブンプレート5とサイドプレート3との間には、樹脂スペーサ10が存在し、ドライブプレート2とドリブンプレート5とサイドプレート3との軸方向での相対的な位置決めが行われている。また、樹脂スペーサ10の存在により、相対的に回転するドライブプレート2,サイドプレート3とドリブンプレート5との直接接触が回避され、直接接触による音の発生と摩耗が防止される。ドライブプレート2,サイドプレート3と一体に回転する樹脂スペーサ10に対し、ドリブンプレート5が相対的に回転するので、軸方向については、樹脂スペーサ10のフランジ部10aはドリブンプレート5と摺動して摩耗する。   As shown in FIG. 1, resin spacers 10 exist between the driven plate 5 and the drive plate 2 and between the driven plate 5 and the side plate 3, and the drive plate 2, the driven plate 5, and the side plate 3. Relative positioning in the axial direction is performed. In addition, the presence of the resin spacer 10 avoids direct contact between the drive plate 2 and the side plate 3 and the driven plate 5 that rotate relatively, thereby preventing sound generation and wear due to direct contact. Since the driven plate 5 rotates relative to the resin spacer 10 that rotates integrally with the drive plate 2 and the side plate 3, the flange portion 10 a of the resin spacer 10 slides on the driven plate 5 in the axial direction. Wear.

次に、樹脂スペーサ10の半径方向の摩耗については、以下のようになる。ドリブンプレート5は、サイドプレート3に対して、樹脂スペーサ10の筒部10bを介してセンタリングされている。即ち、ストッパボルト11を介してサイドプレート3と樹脂スペーサ10とが一体回転し、図1中の右側の樹脂スペーサ10の筒部10bの内周面に対し、ドリブンプレート5と一体の出力ハブ6の外周面6aが摺動し、サイドプレート3,樹脂スペーサ10に対してドリブンプレート5が相対的に回転する。   Next, the radial wear of the resin spacer 10 is as follows. The driven plate 5 is centered with respect to the side plate 3 via the cylindrical portion 10 b of the resin spacer 10. That is, the side plate 3 and the resin spacer 10 rotate integrally through the stopper bolt 11, and the output hub 6 integrated with the driven plate 5 with respect to the inner peripheral surface of the cylindrical portion 10 b of the resin spacer 10 on the right side in FIG. , The driven plate 5 rotates relative to the side plate 3 and the resin spacer 10.

ここで、筒部10bの内周面には図3(a)に示すように摺動部10dが円周方向に沿って間欠的に形成されているので、出力ハブ6の外周面6aと摺動する摺動面10cの面圧が大きい。このため、摺動部10dの摩耗の速度は、摺動面10cが円周の全体に亘って存在する場合に比べて大きくなる。従って、樹脂スペーサ10の半径方向については、筒部10bの内周面の全体が摺動する場合よりも摩耗速度が早くなる。このため、サイドプレート3とドリブンプレート5との軸心が相対的に僅かにずれていた場合は、経時使用によって摺動部10dが摩耗し、ミスアライメントが吸収される。   Here, since the sliding portion 10d is intermittently formed along the circumferential direction on the inner peripheral surface of the cylindrical portion 10b as shown in FIG. 3A, it slides on the outer peripheral surface 6a of the output hub 6. The surface pressure of the sliding surface 10c that moves is large. For this reason, the speed of wear of the sliding portion 10d is larger than that when the sliding surface 10c exists over the entire circumference. Therefore, in the radial direction of the resin spacer 10, the wear rate is faster than when the entire inner peripheral surface of the cylindrical portion 10b slides. For this reason, when the axial centers of the side plate 3 and the driven plate 5 are slightly shifted relative to each other, the sliding portion 10d is worn by use over time, and misalignment is absorbed.

つまり、樹脂スペーサ10は、半径方向については摩耗速度が促進されるため軸心のズレを許容できる一方、軸方向については摩耗が促進されることはなく、軸方向での摩耗に対して半径方向での摩耗の速度を増減させることが出来る。摩耗速度の増減は、摺動部10dの円周方向の長さを増減したり、摺動部10dの数を増減したりすることにより、調整できる。また、樹脂スペーサ10としては、軸方向の摩耗が抑制されるように比較的摩耗耐力のある材料を用いるのが好ましく、例えば66ナイロン等が用いられる。   In other words, the resin spacer 10 can tolerate axial misalignment because the wear rate is accelerated in the radial direction, but the wear is not promoted in the axial direction, and the radial direction against the wear in the axial direction. It is possible to increase or decrease the rate of wear at. The increase / decrease in the wear rate can be adjusted by increasing / decreasing the circumferential length of the sliding portion 10d or increasing / decreasing the number of the sliding portions 10d. Further, as the resin spacer 10, it is preferable to use a material having a relatively high wear resistance so that axial wear is suppressed. For example, 66 nylon or the like is used.

この発明によれば、樹脂スペーサ10は、相対的に回転するドライブプレート2,サイドプレート3とドリブンプレート5との軸方向間に存在し、軸方向での摩耗は少ない。一方、半径方向では、樹脂スペーサ10の筒部10bが、ドリブンプレート5に結合された出力ハブ6の外周面6aとサイドプレート3の内周面3cとの間に介装されており、筒部10bの内周面であって出力ハブ6の外周面6aと摺動する面には、摺動により摩耗する摺動部10dが形成されているので、半径方向での摩耗は促進される。従って、摩耗を促進させて軸心のズレを吸収したいドライブプレート2,サイドプレート3とドリブンプレート5とのセンタリングと、摩耗を促進させることなくドライブプレート2,サイドプレート3とドリブンプレート5との軸方向の位置関係を変えたくない軸方向での位置決めとの相反する作用が行われる。   According to this invention, the resin spacer 10 exists between the axial direction of the drive plate 2, the side plate 3, and the driven plate 5 that rotate relatively, and wear in the axial direction is small. On the other hand, in the radial direction, the cylindrical portion 10 b of the resin spacer 10 is interposed between the outer peripheral surface 6 a of the output hub 6 coupled to the driven plate 5 and the inner peripheral surface 3 c of the side plate 3. Since the sliding portion 10d that is worn by sliding is formed on the inner circumferential surface of 10b and the surface that slides with the outer circumferential surface 6a of the output hub 6, wear in the radial direction is promoted. Therefore, the centering of the drive plate 2, the side plate 3 and the driven plate 5 that wants to promote wear and absorb the misalignment of the shaft center, and the shaft of the drive plate 2, the side plate 3 and the driven plate 5 without promoting wear. There is an effect opposite to the positioning in the axial direction in which the positional relationship of the direction is not desired to be changed.

この発明によれば、樹脂スペーサ10の筒部10bの内周面の出力ハブ6の外周面6aと摺動する面に、複数の摺動部10dを円周方向へ間欠的に形成し、出力ハブ6の外周面6aと摺動する部分の面圧を高くして摩耗部を形成したので、摩耗部の摩耗が促進される。従って、ドライブプレート2,サイドプレート3とドリブンプレート5との軸心が僅かにずれていても、軸心のズレを吸収できる。   According to the present invention, a plurality of sliding portions 10d are intermittently formed in the circumferential direction on a surface that slides with the outer peripheral surface 6a of the output hub 6 on the inner peripheral surface of the cylindrical portion 10b of the resin spacer 10 for output. Since the wear portion is formed by increasing the surface pressure of the sliding portion with the outer peripheral surface 6a of the hub 6, the wear of the wear portion is promoted. Therefore, even if the shaft centers of the drive plate 2, the side plate 3, and the driven plate 5 are slightly shifted, the shift of the shaft center can be absorbed.

この発明によれば、入力部材がドライブプレート2とサイドプレート3(一対の側板)によって構成されているので、ドライブプレート2,サイドプレート3とドリブンプレート5との軸方向間に配置される樹脂スペーサ10も一対となる。
(b)実施の形態2
次に、実施の形態2について説明する。なお、実施の形態2は実施の形態1の一部を変更したものなので、実施の形態1と異なる部分のみを説明する。
According to the present invention, since the input member is constituted by the drive plate 2 and the side plate 3 (a pair of side plates), the resin spacer disposed between the drive plate 2, the side plate 3 and the driven plate 5 in the axial direction. 10 is also a pair.
(B) Embodiment 2
Next, a second embodiment will be described. Since the second embodiment is obtained by changing a part of the first embodiment, only parts different from the first embodiment will be described.

実施の形態1の図3では筒部10bの内周面にのみ摺動部10dを形成したが、図4に示すように筒部10bの外周面にもサイドプレート3の内周面3cと摺動する摺動面10fを有する摺動部10gを円周方向へ間欠的に複数形成し、摺動部10dと摺動部10gとが円周方向に沿って交互配置となるようにしてもよい。この場合は、摺動部10gとサイドプレート3の内周面3cとが摺動するように、ストッパボルト11は設けない。   In FIG. 3 of the first embodiment, the sliding portion 10d is formed only on the inner peripheral surface of the cylindrical portion 10b. However, as shown in FIG. 4, the outer peripheral surface of the cylindrical portion 10b also slides with the inner peripheral surface 3c of the side plate 3. A plurality of sliding portions 10g having a sliding surface 10f that moves may be intermittently formed in the circumferential direction so that the sliding portions 10d and the sliding portions 10g are alternately arranged along the circumferential direction. . In this case, the stopper bolt 11 is not provided so that the sliding portion 10g and the inner peripheral surface 3c of the side plate 3 slide.

この発明によれば、筒部10bの内周面と外周面とに円周方向に沿って交互に摺動部10dと摺動部10gとを形成したので、樹脂スペーサ10の筒部10bが半径方向へ撓み易く弾性の性質を有するに至る。従って、樹脂スペーサ10の筒部10bの摩耗による軸心のズレの吸収に加えて弾性の性質による軸心のズレの吸収が加わり、軸心のズレの吸収機能が一段と高くなる。なお、ストッパボルト11を設けて摺動部10gと摺動するサイドプレート3の内周面3cとが摺動しない構成にしてもよい。摺動しない構成にした場合は、摺動部10gは単なる当接部となる。   According to the present invention, since the sliding portions 10d and the sliding portions 10g are alternately formed along the circumferential direction on the inner peripheral surface and the outer peripheral surface of the cylindrical portion 10b, the cylindrical portion 10b of the resin spacer 10 has a radius. It tends to bend in the direction and has an elastic property. Therefore, in addition to the absorption of the shift of the axial center due to the wear of the cylindrical portion 10b of the resin spacer 10, the absorption of the shift of the axial center due to the elastic property is added, and the function of absorbing the shift of the axial center is further enhanced. Note that the stopper bolt 11 may be provided so that the sliding portion 10g and the inner peripheral surface 3c of the side plate 3 that slides do not slide. In the case of a configuration that does not slide, the sliding portion 10g is a simple contact portion.

なお、実施の形態1,2では入力部材を一対の側板により構成する一方、出力部材を中央板により構成したが、入力部材および出力部材を単一の部材によって構成しても良い。また、入力部材を中央板により構成する一方、出力部材を一対の側板により構成してもよい。更に、実施の形態1,2ではスペーサとして樹脂スペーサを用いたが、樹脂に限定せず、他の材質を用いてもよい。また更に、実施の形態1,2では樹脂スペーサの筒部が外周面形成部としての出力ハブの外周面と側板の内周面との間に配置された場合について示したが、中央板の半径方向外周側に軸方向へ突出する内周面形成部を形成した場合は、樹脂スペーサの筒部は側板の外周面と中央板の内周面形成部との間に配置されることになる。また更に、実施の形態1,2では中央板に結合した出力ハブの外周面を外周面形成部として用いたが、中央板の端面に軸方向へ突出する外周面形成部を一体形成し、その外周面を用いてもよい。また更に、実施の形態1,2では一対の樹脂スペーサのうちの一方のみが出力ハブの外周面と摺動するように構成したが、双方が摺動するようにしてもよい。また更に、実施の形態1では筒部の内周面が摺動する面となり、実施の形態1,2では筒部の内周面および外周面が摺動する面となり、摺動する面に摩耗部が形成されているが、筒部の外周面のみを摺動する面にして外周面のみに摩耗部を形成してもよい。また更に、摩耗部は接触部を円周方向へ間欠的に形成した構成に限らず、磨耗しやすい他の材料を貼り付けても良い。   In the first and second embodiments, the input member is constituted by a pair of side plates, while the output member is constituted by a central plate. However, the input member and the output member may be constituted by a single member. Further, the input member may be constituted by a central plate, while the output member may be constituted by a pair of side plates. Furthermore, although resin spacers are used as the spacers in the first and second embodiments, the present invention is not limited to resins, and other materials may be used. Furthermore, in the first and second embodiments, the case where the cylindrical portion of the resin spacer is disposed between the outer peripheral surface of the output hub as the outer peripheral surface forming portion and the inner peripheral surface of the side plate is shown. When the inner peripheral surface forming portion protruding in the axial direction is formed on the outer peripheral side in the direction, the cylindrical portion of the resin spacer is arranged between the outer peripheral surface of the side plate and the inner peripheral surface forming portion of the central plate. Furthermore, in the first and second embodiments, the outer peripheral surface of the output hub coupled to the central plate is used as the outer peripheral surface forming portion, but the outer peripheral surface forming portion protruding in the axial direction is integrally formed on the end surface of the central plate, An outer peripheral surface may be used. In the first and second embodiments, only one of the pair of resin spacers slides on the outer peripheral surface of the output hub, but both may slide. Furthermore, in the first embodiment, the inner peripheral surface of the cylindrical portion is a sliding surface, and in the first and second embodiments, the inner peripheral surface and the outer peripheral surface of the cylindrical portion are sliding surfaces. Although the portion is formed, the wear portion may be formed only on the outer peripheral surface with only the outer peripheral surface of the cylindrical portion sliding. Furthermore, the wear part is not limited to the structure in which the contact part is intermittently formed in the circumferential direction, and other materials that are easily worn may be attached.
