Description

【０００１】
【発明の属する技術分野】
この発明は一方向クラッチに関し、特に部品点数を減らして軽量化を図り、コストも低減できる一方向クラッチに関する。
【０００２】
【従来の技術】
一方向クラッチでは、外輪と内輪との間の環状空間に、動力伝達時に楔作用をし、動力遮断時に自由回転を許容する部材としてスプラグが配置される。このスプラグを環状空間の周方向一定間隔に保持するために保持器が用いられ、また、一方向クラッチには通常、係合方向にスプラグを付勢するリボンスプリングやガータスプリング等が同時に組み込まれる。このような一方向クラッチの保持器として、例えば、図６及び図６のＡーＡ矢視断面図である図７に示すように、外輪１１と内輪１２との間にスプラグ１３が周方向一定間隔で配置されるが、これらのスプラグ１３を保持する外側保持器１４と、内側保持器１６とが用いられ、スプリング１５によりスプラグ１３は常に係合方向（楔作用方向）に付勢されて組み込まれている（特許文献１）。この場合、外側保持器１４は、端部に設けたフランジ部１４ｆの外周面が外輪内周面に圧入嵌合され、外輪１１と一体的に（時計方向および反時計方向）一定範囲往復回転するように組み込まれている。

【発明が解決しようとする課題】
上記するように、従来の一方向クラッチでは、二つの保持器が使用される例が多く部品点数も多い。更に、一方向クラッチではこれら二つの保持器に加えてリボンスプリング又はガータスプリングでスプラグを楔作用側へ付勢して組み込まなければならず作業も煩雑である。また、部品点数が多くなると重量も大きくなるという問題がある。一方、図８は、外輪２１と内輪２２との間の環状空間に一つの保持器２４を用いた一方向クラッチであるが、この一つの保持器２４を使用する一方向クラッチでは、軽量化と部品点数の軽減等メリットもあるが、通常一つの保持器２４は、外輪側寄りに組み込まれるため、この図８に示すように、内輪２２を組み込む際、スプラグ２３が傾斜し、内輪２２の外側端部と干渉することが多く、組み込み作業がやりづらいという問題がある。
【０００４】
この発明は、上記する課題に対処するためになされたものであり、一つの保持器を用いて重量軽減を図ると共に、組立時のスプラグの傾斜を防止し組立やすく、部品点数の減少と製作コスト等も低減できる一方向クラッチを提供することを目的としている。
【０００５】
【課題を解決するための手段】
即ち、この発明は上記する課題を解決するために、請求項１に記載の発明は、外輪（１）と内輪（２）との間の環状空間に、外周面を前記外輪内周面に圧接するフランジ部（４ｆ）と周方向にスプラグ（３）を配置するポケット（４ｐ）とを設けた単一の保持器（４）を備えた一方向クラッチにおいて、
前記外輪（１）の片側端部に内径方向へ延設されるフランジ部（１ｆ）を設けると共に、該フランジ部（１ｆ）の内側に、前記内輪（２）外径と対向する内周面（１ｉ）を、且つ該内周面（１ｉ）より径外方へ前記保持器（４）のフランジ部（４ｆ）と同幅の厚さ（ｔ）でスプラグ側に延設される環状凸部（１ｐ）を一体的に設けたことを特徴とするものである。
【０００６】
また、請求項２に記載の発明は、外輪（１）と内輪（２）との間の環状空間に、外周面を前記外輪内周面に圧接するフランジ部（４ｆ）と周方向にスプラグ（３）を配置するポケット（４ｐ）とを設けた単一の保持器を備えた一方向クラッチにおいて、
前記外輪（１）の片側端部に内径方向へ延設されるフランジ部（１ｆ）を設けると共に、該フランジ部（１ｆ）の内側に、前記内輪外径と対向する内周面（１ｉ）を、且つ該内周面（１ｉ）より径外方へ前記保持器フランジ部（４ｆ）と同幅のリング（６）を別体として配置したことを特徴とするものである。
【０００７】
更に、請求項３に記載の発明は、外輪（７）と内輪（２）との間の環状空間に、外周面を前記外輪内周面に圧接するフランジ部（４ｆ）と周方向にスプラグ（３）を配置するポケット（４ｐ）とを設けた単一の保持器を備えた一方向クラッチにおいて、
前記外輪（１）は、片側端部に内径方向へ延設されるフランジ部（８ｆ）を設けたトルクコンバータのステータボス部（８ｂ）に嵌め入れると共に、前記フランジ部（８ｆ）の内側に、前記内輪外径と対向する内周面（８ｉ）を、且つ径外方へ前記保持器のフランジ部と同幅でスプラグ側に延設される環状凸部（８ｐ）を一体的に設けたことを特徴とするものである。
【０００８】
更に、上記請求項４に記載の発明は、外輪（７）と内輪（２）との間の環状空間に、外周面を前記外輪内周面に圧接するフランジ部（４ｆ）と周方向にスプラグ（３）を配置するポケット（４ｐ）とを設けた単一の保持器を備えた一方向クラッチにおいて、
前記外輪（７）は、片側端部に内径方向へ延設されるフランジ部（８ｆ）を設けたトルクコンバータのステータボス部（８ｂ）に嵌め入れ、前記フランジ部（８ｆ）の内側に、前記内輪（２）外径と対向する内周面（８ｉ）を、且つ該内周面（８ｉ）より径外方へ前記保持器フランジ部（４ｆ）と同幅のリング（６）を配置したことを特徴とするものである。
【０００９】
上記各手段によれば、一方向クラッチに一つの保持器を用いた場合で且つ外輪寄りに保持器やスプリングを組みスプラグを配置して内輪を組み入れる場合でも外輪或いはステータのフランジ部に設けた環状凸部やリングの側面でスプラグがが傾斜するのを阻止することができるため、組み込み性が極めて良くなる。
【００１０】
【発明の実施の形態】
以下、この発明の具体的実施の形態について図面を参照ながら説明する。
図１は、この発明の一方向クラッチの軸方向の一部断面図、図２はこの一方向クラッチを構成する外輪の一部斜視図である。
【００１１】
この一方向クラッチは、外輪１と、内輪２との間の環状空間に周方向等間隔に設けたポケット４ｐに、スプラグ３を配置した単一の保持器４と、スプリング５とが配置されて構成されている。この場合、前記外輪１の片側端部には内径方向へ延設されるフランジ部１ｆが設けられている。そして該フランジ部１ｆの内側面には、環状凸部１ｐが一体的に設けられている。また、前記保持器４には、端部はフランジ部４ｆと、周方向にポケット４ｐが形成され、該フランジ部４ｆは外輪１の内周面１ｏに圧入（圧接）され、該外輪１と一体的に動作するようにしてある。更に、スプリング５には、ポケット部５ｐが形成されてスプラグ３が配置され且つ該スプラグ３を楔作用する方向に付勢している。
【００１２】
前記外輪１のフランジ部１ｆの内側面に設けられる環状凸部１ｐは、前記内輪２の外径と対向する内周面１ｉを有し、且つ該内周面より径外方へスプラグ３側に（軸方向に）延設して一体的に設けられている。該環状凸部１ｐの幅ｈは、前記保持器４のフランジ部４ｆの厚みｔと同等であることが望ましい。
【００１３】
図３は、この発明の第２の実施の形態を示す軸方向の一部断面図である。即ち、第１の実施の形態においては、外輪１の片側端部の内径方向へ延設されるフランジ部１ｆの内側面に、環状凸部１ｐを一体的に設けるものである。しかし該環状凸部１ｐを外輪１のフランジ部１ｆの内側面に設けるのではなく、この図３に示すように、該環状凸部１ｐの代わりに同じ内径と外径及び厚さを有するリング６を前記環状凸部１ｐの位置に配置しても良い。このようなリング６を配置しても１つの保持器４を用いた一方向クラッチの組立の際スプラグ３の傾斜を防止して組み込み作業をスムーズに行うことができる。
【００１４】
上記するように、この発明の一方向クラッチは、外輪１の片側端部に内径方向へ延設されるフランジ部１ｆを設けると共に、該フランジ部１ｆの内側に、前記内輪２の外径と対向する内周面１ｉを、且つ該内周面より径外方へ、スプラグ３側に（軸方向に）延設される環状凸部１ｐを一体的に設けるか、或いは該環状凸部１ｐ部分と同一寸法のリング６を配置することを特徴とするものである。この場合、該環状凸部１ｐの厚み或いはリング６の厚みｈは、保持器４に設けたフランジ部４ｆの厚さｔと同等とするものである。しかし、この発明の一方向クラッチは、トルクコンバータのステータに組み込む構成とすることもできる。
【００１５】
図４は、この発明の一方向クラッチの第３の実施の形態を示す図である。即ち、この実施の形態の一方向クラッチでは、前記外輪１の代わりに、通常のものと同様にフランジ部１ｆの無い外輪７を用いてあり、外輪７と、トルクコンバータ用ステータ８と、フランジ部４ｆと周方向にスプラグ配置用ポケット４ｐを設けた保持器４と、スプリング５と、前記保持器４のポケット４ｐに配置されるスプラグ３と、内輪２と、で構成される。前記ステータボス部８ｂには、片側端部に内径方向へ延設されるフランジ部８ｆが設けてあり、該フランジ部８ｆの内側に、前記内輪外径と対向する内周面８ｉを、且つ該内周面８ｉより径外方へ前記保持器４のフランジ部４ｆと同幅でスプラグ３側に（軸方向に）延設される環状凸部８ｐが一体的に設けられている。
【００１６】
上記するように、トルクコンバータにおいて、ステータ８に上記するようにな一方向クラッチを構成すれば、一方向クラッチに一つの保持器４を用いた場合でも組み込み作業に際してスプラグ３が傾斜するのをこの環状凸部８ｐの側面で阻止することができるため、組み込み性が極めて良くなる。
【００１７】
図５は、この発明の第４の実施の形態を示す図である。即ち、第３の実施の形態においては、ステータ８のボス部に外輪７を嵌合させ、該ステータボス部８ｂの片側端部の内径方向へ延設されるフランジ部８ｆの内側面に、環状凸部８ｐを一体的に設けた。しかし該環状凸部８ｐをステータ８のフランジ部８ｆの内側面に一体的に設けるのではなく、この図５に示すように、該環状凸部８ｐの代わりに同じ内径と外径及び厚さを有するリング６をこのステータ８のフランジ部８ｆの環状凸部８ｐの位置に配置しても良い。このようなリング６を配置しても１つの保持器４を用いた一方向クラッチの組立の際スプラグ３の傾斜を防止して内輪等の組み込み作業をスムーズに行うことができる。
【００１８】
【発明の効果】
以上、詳述したように、この発明の一方向クラッチによれば、単一の保持器を用いた場合であっても、保持器やスプリングおよびスプラグを組み込み、更に外輪にこれらを外輪やステータに組み込み、内輪を挿入する場合でもスプラグが干渉しても軸方向に傾斜しなくなり、組み込み作業が極めてスムーズとなる。また、部品点数も少ないのでコストの低減を図り重量も軽減することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a one-way clutch, and more particularly, to a one-way clutch that can be reduced in weight by reducing the number of parts and cost.
[0002]
[Prior art]
In the one-way clutch, a sprag is disposed in the annular space between the outer ring and the inner ring as a member that acts as a wedge when power is transmitted and allows free rotation when power is interrupted. A retainer is used to hold the sprags at regular intervals in the circumferential direction of the annular space, and a one-way clutch usually incorporates a ribbon spring, a garter spring, or the like that urges the sprags in the engagement direction. As such a one-way clutch retainer, for example, as shown in FIG. 7 which is a cross-sectional view taken along the line AA in FIGS. 6 and 6, a sprag 13 is fixed between the outer ring 11 and the inner ring 12 in the circumferential direction. Although arranged at intervals, an outer retainer 14 and an inner retainer 16 for holding these sprags 13 are used, and the sprags 13 are always urged and incorporated in the engagement direction (wedge action direction) by the spring 15. (Patent Document 1). In this case, the outer retainer 14 is press-fitted and fitted with the outer peripheral surface of the flange portion 14f provided at the end thereof to the inner peripheral surface of the outer ring, and reciprocates within a certain range integrally with the outer ring 11 (clockwise and counterclockwise). Built in.

[Problems to be solved by the invention]
As described above, in the conventional one-way clutch, there are many examples in which two cages are used, and the number of parts is also large. Further, in the one-way clutch, the sprags must be urged and incorporated in the wedge action side by a ribbon spring or a garter spring in addition to these two cages, and the work is complicated. There is also a problem that the weight increases as the number of parts increases. On the other hand, FIG. 8 shows a one-way clutch using one retainer 24 in the annular space between the outer ring 21 and the inner ring 22, but the one-way clutch using this one retainer 24 is reduced in weight. Although there is a merit such as a reduction in the number of parts, since one cage 24 is usually assembled closer to the outer ring side, the sprag 23 is inclined when the inner ring 22 is assembled as shown in FIG. There is a problem that it often interferes with the end portion, making it difficult to perform the assembling work.
[0004]
The present invention has been made to cope with the above-mentioned problems, and while reducing the weight by using one cage, it is easy to assemble by preventing the inclination of sprags during assembly, reducing the number of parts and manufacturing cost. It is an object to provide a one-way clutch that can reduce the above.

That is, in the first embodiment, the annular convex portion 1p is integrally provided on the inner surface of the flange portion 1f extending in the inner diameter direction of the one end portion of the outer ring 1. However, the annular convex portion 1p is not provided on the inner surface of the flange portion 1f of the outer ring 1, but a ring 6 having the same inner diameter, outer diameter and thickness is used instead of the annular convex portion 1p as shown in FIG. May be arranged at the position of the annular convex portion 1p. Even when such a ring 6 is arranged, the assembling work can be performed smoothly by preventing the inclination of the sprag 3 during the assembly of the one-way clutch using the single retainer 4.
