Description

この発明は、動力の伝達と遮断の切り換えに用いられる回転伝達装置に関するものである。   The present invention relates to a rotation transmission device used for switching between power transmission and cutoff.

ＦＲベースの４輪駆動車において、補助駆動輪としての前輪に駆動力の伝達と遮断とを行なう回転伝達装置として、特許文献１に記載されたものが従来から知られている。   In an FR-based four-wheel drive vehicle, a rotation transmission device described in Patent Document 1 is conventionally known as a rotation transmission device that transmits and blocks driving force to a front wheel as an auxiliary driving wheel.

上記特許文献１に記載された回転伝達装置においては、入力軸にカムリングを取付け、そのカムリングとその外側に設けられた外輪の相互間に２方向クラッチと、電磁クラッチとを組込み、上記電磁クラッチにより２方向クラッチのオン、オフを制御し、その２方向クラッチのオンによりカムリングと外輪とを結合して、入力軸の回転トルクを外輪に伝達し、その外輪の回転トルクを前輪に伝えるようにしている。   In the rotation transmission device described in Patent Document 1, a cam ring is attached to an input shaft, a two-way clutch and an electromagnetic clutch are assembled between the cam ring and an outer ring provided outside the cam ring, and the electromagnetic clutch The on / off of the two-way clutch is controlled, the cam ring and the outer ring are coupled by turning on the two-way clutch, the rotational torque of the input shaft is transmitted to the outer ring, and the rotational torque of the outer ring is transmitted to the front wheel. Yes.

ここで、２方向クラッチは、外輪の内周に円筒面を形成し、カムリングの外周には上記円筒面との間でくさび形空間を形成する複数のカム面を周方向に間隔をおいて設け、各カム面と円筒面間にローラを組込み、そのローラを保持器により保持して、カムリングに対する保持器の相対回転によりローラを円筒面およびカム面に係合させるようにしている。また、カムリングと保持器の相互間にスイッチばねを組込み、上記カムリングと保持器の相対回転によりスイッチばねを弾性変形させ、その復元弾性によってローラが係合解除される中立位置に保持器を復帰回転させるようにしている。   Here, the two-way clutch has a cylindrical surface formed on the inner periphery of the outer ring, and a plurality of cam surfaces that form a wedge-shaped space between the outer periphery of the cam ring and the cylindrical surface. A roller is incorporated between each cam surface and the cylindrical surface, the roller is held by a cage, and the roller is engaged with the cylindrical surface and the cam surface by relative rotation of the cage with respect to the cam ring. Also, a switch spring is incorporated between the cam ring and the cage, the switch spring is elastically deformed by the relative rotation of the cam ring and the cage, and the cage is returned to the neutral position where the roller is disengaged by its restoring elasticity. I try to let them.

一方、電磁クラッチは、保持器に対して回り止めされ、かつ軸方向に移動可能に支持されたアーマチュアと、外輪に嵌合されてアーマチュアと軸方向で対向するロータと、そのロータに対向配置された電磁石とを有し、上記電磁石の電磁コイルに対する通電によりアーマチュアをロータに吸着して保持器に前記スイッチばねのばね力を超えるスイッチトルクを負荷し、保持器とカムリングの相対回転により、ローラを円筒面およびカム面に係合させるようにしている。   On the other hand, the electromagnetic clutch is secured to the retainer and supported so as to be movable in the axial direction, a rotor fitted to the outer ring and opposed to the armature in the axial direction, and opposed to the rotor. The magnet is attracted to the rotor by energizing the electromagnetic coil of the electromagnet, and the cage is loaded with a switch torque exceeding the spring force of the switch spring, and the roller is rotated by the relative rotation of the cage and the cam ring. It is made to engage with a cylindrical surface and a cam surface.

上記の構成から成る電磁クラッチにおいて、保持器に対してアーマチュアを回り止めし、かつ、軸方向に移動可能とするため、保持器とアーマチュアの連結に図１４（Ｉ）に示す連結構造を採用する場合が多くなっている。   In the electromagnetic clutch having the above-described configuration, the connection structure shown in FIG. 14 (I) is employed for connection between the retainer and the armature in order to prevent the armature from rotating with respect to the retainer and to be movable in the axial direction. There are many cases.

上記連結構造は、保持器４０の端部内にコネクティングプレート４１を嵌合し、そのコネクティングプレート４１の外周に形成された係合片４２を保持器４０の端部に設けられた切欠部４３に嵌合してコネクティングプレート４１を回り止めし、このコネクティングプレート４１の係合片４２をアーマチュア４４に形成された係合孔４５に挿入して、アーマチュア４４を回り止めし、かつ軸方向に移動自在としている。   In the connecting structure, the connecting plate 41 is fitted into the end of the cage 40, and the engaging piece 42 formed on the outer periphery of the connecting plate 41 is fitted into the notch 43 provided at the end of the cage 40. Accordingly, the connecting plate 41 is prevented from rotating, and the engaging piece 42 of the connecting plate 41 is inserted into the engaging hole 45 formed in the armature 44 to prevent the armature 44 from rotating and to be movable in the axial direction. Yes.

なお、図１４（Ｉ）に示す４６はカムリングを示し、また、４７はアーマチュア４４に対向したロータ、４８はロータ４７に対向した電磁石を示す。
特開平１０−２１１８２８号公報 In FIG. 14I, 46 indicates a cam ring, 47 indicates a rotor facing the armature 44, and 48 indicates an electromagnet facing the rotor 47.
Japanese Patent Laid-Open No. 10-211828

ところで、図１４（Ｉ）に示す連結構造を採用した従来の回転伝達装置においては、各部品の寸法公差が最も悪い状態で係合片４２の先端がロータ４７の摩擦面に接触しないようにする必要があるため、係合片４２はある一定以上長くすることはできない。   By the way, in the conventional rotation transmission device employing the connection structure shown in FIG. 14 (I), the tip of the engagement piece 42 is prevented from coming into contact with the friction surface of the rotor 47 with the dimensional tolerance of each component being the worst. Since it is necessary, the engagement piece 42 cannot be longer than a certain length.

このため、電磁石４８の電磁コイルに対する通電によって図１４（II）に示すように、ロータ４７にアーマチュア４４を吸着すると、係合片４２と係合孔４５の接触長さＬが短くなり、接触面積が減少する状態で保持器４０にスイッチトルクが負荷されるため、係合片４２と係合孔４５の接触面での面圧が高く、上記接触面で摩耗や破損が発生するおそれがある。   For this reason, when the armature 44 is attracted to the rotor 47 by energizing the electromagnetic coil of the electromagnet 48 as shown in FIG. 14 (II), the contact length L between the engagement piece 42 and the engagement hole 45 is shortened. Since the switch torque is applied to the cage 40 in a state in which the contact pressure decreases, the contact pressure between the contact surfaces of the engagement pieces 42 and the engagement holes 45 is high, and the contact surfaces may be worn or damaged.

なお、保持器４０に対してアーマチュア４４を回り止めし、かつ軸方向に移動可能とするため、図１４（Ｉ）に示すコネクティングプレート４１を省略し、保持器の端面に係合片を設け、その係合片をアーマチュアに形成された係合孔に挿入するようにした連結構造も従来から知られているが、この場合も図１４（Ｉ）に示す連結構造と同様に、アーマチュアの吸着状態での係合片と係合孔の接触長さが短く、接触面での摩耗や破損が発生するおそれがあった。   In order to prevent the armature 44 from rotating with respect to the cage 40 and to be movable in the axial direction, the connecting plate 41 shown in FIG. 14 (I) is omitted, and an engagement piece is provided on the end surface of the cage. A connecting structure in which the engaging piece is inserted into an engaging hole formed in the armature is also known in the past. In this case as well, as in the connecting structure shown in FIG. In this case, the contact length between the engagement piece and the engagement hole is short, and there is a possibility that the contact surface may be worn or damaged.

この発明の課題は、保持器に対して電磁クラッチのアーマチュアを回り止めし、かつ軸方向に移動可能とした回転伝達装置において、保持器にスイッチトルクを伝達する接触部での摩耗や破損を防止することである。   An object of the present invention is to prevent wear and breakage at a contact portion that transmits switch torque to a cage in a rotation transmission device that prevents the armature of an electromagnetic clutch from rotating with respect to the cage and is movable in an axial direction. It is to be.

電磁石２４は固定部材Ａに支持されてロータガイド５内に配置され、その電磁石２４の電磁コイル２４ａに対する通電によりアーマチュア２２はロータ２３に吸着されるようになっている。   The electromagnet 24 is supported by the fixing member A and disposed in the rotor guide 5, and the armature 22 is attracted to the rotor 23 by energizing the electromagnetic coil 24 a of the electromagnet 24.

第１の実施形態で示す回転伝達装置は上記の構造から成り、電磁石２４の電磁コイル２４ａに対する通電の遮断状態では、２方向クラッチ１０の係合子１３はスイッチばね１６によって円筒面１１およびカム面１２に対して係合解除された中立位置に保持されている。   The rotation transmission device shown in the first embodiment has the above-described structure. When the energization of the electromagnet 24 to the electromagnetic coil 24a is interrupted, the engagement element 13 of the two-way clutch 10 is switched by the switch spring 16 to the cylindrical surface 11 and the cam surface 12. Is held in the neutral position released from engagement.

このため、内輪１が回転しても、その回転は外輪２に伝達されない。このとき、内輪１と保持器１４の相互間にはスイッチばね１６が組込まれているため、内輪１と共に保持器１４が回転し、また、保持器１４に回り止めされたコネクティングプレート２１を介して保持器１４の回転はアーマチュア２２に伝達され、アーマチュア２２も回転する。   For this reason, even if the inner ring 1 rotates, the rotation is not transmitted to the outer ring 2. At this time, since the switch spring 16 is incorporated between the inner ring 1 and the retainer 14, the retainer 14 rotates together with the inner ring 1, and via a connecting plate 21 that is prevented from rotating around the retainer 14. The rotation of the cage 14 is transmitted to the armature 22, and the armature 22 also rotates.

内輪１の回転状態において、電磁クラッチ２０の電磁コイル２４ａに通電すると、アーマチュア２２に吸引力が付与され、アーマチュア２２はロータ２３に向けて移動してロータ２３に吸着される。その吸着面に作用する摩擦抵抗はアーマチュア２２の回転抵抗となり保持器１４にスイッチトルクが作用して内輪１と保持器１４とが相対回転する。その回転によって係合子１３は円筒面１１およびカム面１２に係合し、内輪１の回転が外輪２に伝達される。   When the electromagnetic coil 24 a of the electromagnetic clutch 20 is energized while the inner ring 1 is rotating, an attractive force is applied to the armature 22, and the armature 22 moves toward the rotor 23 and is attracted to the rotor 23. The frictional resistance acting on the attracting surface becomes the rotational resistance of the armature 22 and a switch torque acts on the retainer 14 so that the inner ring 1 and the retainer 14 rotate relative to each other. By the rotation, the engaging element 13 is engaged with the cylindrical surface 11 and the cam surface 12, and the rotation of the inner ring 1 is transmitted to the outer ring 2.

また、内輪１と保持器１４の相対回転により、図２に示すスイッチばね１６が弾性変形する。   Further, the switch spring 16 shown in FIG. 2 is elastically deformed by the relative rotation of the inner ring 1 and the cage 14.

このため、電磁コイル２４ａに対する通電を遮断すると、スイッチばね１６のばね力により保持器１４が回転され、係合子１３は円筒面１１およびカム面１２に対して係合解除される中立位置に戻され、内輪１から外輪２への回転伝達が遮断される。   Therefore, when the energization to the electromagnetic coil 24 a is interrupted, the retainer 14 is rotated by the spring force of the switch spring 16, and the engagement element 13 is returned to the neutral position where the engagement with the cylindrical surface 11 and the cam surface 12 is released. The rotation transmission from the inner ring 1 to the outer ring 2 is interrupted.

第１の実施形態における回転伝達装置においては、図２、図５および図６に示すように、アーマチュア２２に形成された係合孔２６の両側部にコネクティングプレート２１に向けて延びる突出部２７を形成しているため、電磁コイル２４ａに対する通電により、アーマチュア２２がロータ２３側に移動して、図６に示すようにロータ２３に吸着され、係合孔２６と係合片２５の接触部から保持器１４にスイッチトルクが伝達されるとき、係合片２５と係合孔２６の接触部での接触面積の減少はない。このため、係合片２５と係合孔２６の接触部での面圧は一定に保持されることになり、上記接触部での摩耗や破損を防止することができる。   In the rotation transmission device in the first embodiment, as shown in FIGS. 2, 5, and 6, protrusions 27 extending toward the connecting plate 21 are formed on both sides of the engagement hole 26 formed in the armature 22. Therefore, the armature 22 moves to the rotor 23 side by energization of the electromagnetic coil 24a, and is attracted to the rotor 23 as shown in FIG. 6, and is held from the contact portion between the engagement hole 26 and the engagement piece 25. When the switch torque is transmitted to the device 14, there is no reduction in the contact area at the contact portion between the engagement piece 25 and the engagement hole 26. For this reason, the surface pressure at the contact portion between the engagement piece 25 and the engagement hole 26 is kept constant, and wear and breakage at the contact portion can be prevented.

ここで、図５および図６では、突出部２７として折曲片から成るものを示したが、突出部２７はこれに限定されるものではない。例えば、図７に示すように、係合孔２６の両側部をアーマチュア２２の厚み範囲内でプレスによる半抜きを行なって突起を形成し、その突起を突出部２７としてもよい。   Here, in FIG. 5 and FIG. 6, the protrusion 27 is composed of a bent piece, but the protrusion 27 is not limited to this. For example, as shown in FIG. 7, the projections 27 may be formed by projecting the both sides of the engagement hole 26 by half-pressing with a press within the thickness range of the armature 22.

突起から成る突出部２７においても、係合片２５と係合孔２６の接触部での接触面積の減少を防止し、上記接触部での摩耗や破損を防止することができる。   Also in the protruding portion 27 made of a protrusion, it is possible to prevent the contact area at the contact portion between the engagement piece 25 and the engagement hole 26 from being reduced, and to prevent wear and breakage at the contact portion.

図８および図９は、この発明に係る回転伝達装置の第２の実施形態を示す。この実施形態では、ロータ２３のアーマチュア２２が接触する摩擦面に、アーマチュア２２の係合孔２６と対応して環状の案内溝２９を形成し、上記係合孔２６に挿入された係合片２５を、その先端部が上記案内溝２９に挿入される長さとした点、および図２に示す突出部２７を省略している点で第１の実施形態で示す回転伝達装置と相違している。   8 and 9 show a second embodiment of the rotation transmission device according to the present invention. In this embodiment, an annular guide groove 29 corresponding to the engagement hole 26 of the armature 22 is formed on the friction surface with which the armature 22 of the rotor 23 contacts, and the engagement piece 25 inserted into the engagement hole 26. Is different from the rotation transmission device shown in the first embodiment in that the tip portion is a length inserted into the guide groove 29 and the protrusion 27 shown in FIG. 2 is omitted.

このため、第１の実施形態で示す回転伝達装置と同一の部品には同一符号を付して説明を省略する。   For this reason, the same code | symbol is attached | subjected to the components same as the rotation transmission apparatus shown in 1st Embodiment, and description is abbreviate | omitted.

第２の実施形態で示すように、ロータ２３に案内溝２９を形成し、コネクティングプレート２１に形成された係合片２５をその先端部が上記案内溝２９に挿入される長さとすることにより、アーマチュア２２がロータ２３に向けて移動してロータ２３に吸着され、保持器１４にスイッチトルクが負荷される場合に、係合片２５と係合孔２６の接触部における接触面積が減少するのを防止することができ、上記接触部での摩耗および破損を防止することができる。   As shown in the second embodiment, the guide groove 29 is formed in the rotor 23, and the engagement piece 25 formed in the connecting plate 21 is set to a length that allows the tip portion to be inserted into the guide groove 29. When the armature 22 moves toward the rotor 23 and is attracted to the rotor 23 and a switch torque is applied to the retainer 14, the contact area at the contact portion between the engagement piece 25 and the engagement hole 26 is reduced. It is possible to prevent wear and breakage at the contact portion.

図１０乃至図１２は、この発明に係る回転伝達装置の第３の実施形態を示す。この実施形態では、保持器１４の端面には複数の係合片３０を設け、各係合片３０をアーマチュア２２に形成された係合孔２６に挿入している点および図１に示すコネクティングプレート２１に代えて押え板３１を保持器１４の端部内に挿入し、その押え板３１を内輪１の端部外周に取付けた止め輪３２により軸方向に非可動に支持してスイッチばね１６を押えるようにしている点で第１の実施形態で示す回転伝達装置と相違している。   10 to 12 show a third embodiment of the rotation transmission device according to the present invention. In this embodiment, a plurality of engagement pieces 30 are provided on the end face of the cage 14, and each engagement piece 30 is inserted into an engagement hole 26 formed in the armature 22, and the connecting plate shown in FIG. Instead of 21, a presser plate 31 is inserted into the end of the retainer 14, and the presser plate 31 is supported in a non-movable manner in the axial direction by a retaining ring 32 attached to the outer periphery of the end of the inner ring 1 to press the switch spring 16. This is different from the rotation transmission device shown in the first embodiment.

このため、第１の実施形態で示す回転伝達装置と同一の部品には同一符号を付して説明を省略する。   For this reason, the same code | symbol is attached | subjected to the components same as the rotation transmission apparatus shown in 1st Embodiment, and description is abbreviate | omitted.

第３の実施形態で示すように、保持器１４の端面に係合片３０を形成し、その係合片３０をアーマチュア２２に形成された係合孔２６に挿入することによって、アーマチュア２２を保持器１４に対して回り止めし、かつ軸方向に移動可能とすることができ、第１の実施形態で示すコネクティングプレート２１を省略することができる。   As shown in the third embodiment, the armature 22 is held by forming the engagement piece 30 on the end face of the retainer 14 and inserting the engagement piece 30 into the engagement hole 26 formed in the armature 22. It can be prevented from rotating with respect to the container 14 and can be moved in the axial direction, and the connecting plate 21 shown in the first embodiment can be omitted.

また、保持器１４の端部内に嵌合されたコネクティングプレート２１に係合片２５を形成する場合、保持器１４の端面によって後退位置が規制されるアーマチュア２２の係合孔２６と係合片２５の相対的な位置は部品の加工誤差や公差によってバラツキが大きくなり、突出部２７の突出長さを大きくとる必要があるが、第３の実施形態で示すように、保持器１４の端面に係合片３０を形成すると、アーマチュア２２の係合孔２６と係合片３０の相対的な位置のバラツキを小さくすることができる。   Further, when the engagement piece 25 is formed on the connecting plate 21 fitted in the end portion of the cage 14, the engagement hole 26 and the engagement piece 25 of the armature 22 whose retreat position is regulated by the end surface of the cage 14. The relative positions of the protrusions 27 vary greatly due to processing errors and tolerances of the parts, and it is necessary to increase the protrusion length of the protrusion 27. However, as shown in the third embodiment, the relative position of the protrusion 14 depends on the end face of the cage 14. When the joining piece 30 is formed, variation in the relative positions of the engaging hole 26 of the armature 22 and the engaging piece 30 can be reduced.

このため、係合孔２６の両側にプレスの半抜きによって突出部２７を形成する場合に、その突出部２７の突出量を少なくすることができ、コストの低減を図ることができる。   For this reason, when the protrusions 27 are formed on both sides of the engagement hole 26 by half-pressing the press, the protrusion amount of the protrusions 27 can be reduced, and the cost can be reduced.

図１３は、この発明に係る回転伝達装置の第４の実施形態を示す。この実施形態では、ロータ２３のアーマチュア２２が接触する摩擦面に、アーマチュア２２の係合孔２６と対応して環状の案内溝３３を形成し、上記係合孔２６に挿入された係合片３０を、その先端部が上記案内溝２９に挿入される長さとした点、および図１１に示す突出部２７を省略している点で図１１に示す第３の実施形態の回転伝達装置と相違している。   FIG. 13 shows a fourth embodiment of the rotation transmission device according to the present invention. In this embodiment, an annular guide groove 33 corresponding to the engagement hole 26 of the armature 22 is formed on the friction surface with which the armature 22 of the rotor 23 contacts, and the engagement piece 30 inserted into the engagement hole 26. Is different from the rotation transmission device of the third embodiment shown in FIG. 11 in that the tip portion is a length inserted into the guide groove 29 and the protrusion 27 shown in FIG. 11 is omitted. ing.

このため、第３の実施形態で示す回転伝達装置と同一の部品には同一符号を付して説明を省略する。   For this reason, the same components as those in the rotation transmission device shown in the third embodiment are denoted by the same reference numerals and description thereof is omitted.

第４の実施形態に示す回転伝達装置においても、図８に示すコネクティングプレート２１を省略することができるため、コストの低減を図ることができる。   Also in the rotation transmission device shown in the fourth embodiment, since the connecting plate 21 shown in FIG. 8 can be omitted, the cost can be reduced.

第１の実施形態乃至第４の実施形態では、外輪２の内周に円筒面１１を形成し、内輪１の外周にカム面１２を形成したが、上記とは逆に、内輪１の外周に円筒面を形成し、外輪２の内周にカム面を形成してもよい。この場合、外輪２と保持器１４の相互間にスイッチばねを組込むと共に、ロータ２３を内輪１に接続される軸に取付けるようにする。   In the first embodiment to the fourth embodiment, the cylindrical surface 11 is formed on the inner periphery of the outer ring 2 and the cam surface 12 is formed on the outer periphery of the inner ring 1. On the contrary, on the outer periphery of the inner ring 1. A cylindrical surface may be formed, and a cam surface may be formed on the inner periphery of the outer ring 2. In this case, a switch spring is incorporated between the outer ring 2 and the cage 14 and the rotor 23 is attached to a shaft connected to the inner ring 1.

In this case, a cylindrical surface is formed on the outer periphery of the inner ring and the inner periphery of the outer ring, the sprags incorporated between the two cylindrical surfaces are held by cages with different diameters, and the cage on the small diameter side is fixed to the inner ring, A switch spring that holds the sprag in a neutral position is incorporated between the radial cage and the inner ring.
