Description

【０００１】
【発明の属する技術分野】
本発明は、外方軌道を有する外方継ぎ手部材、内方軌道を有する内方継ぎ手部材、前記外方軌道および前記内方軌道からなっている軌道対に収容されるトルク伝達ボール、および前記ボールが共通平面内に保持されかつ前記ボールが、前記継ぎ手が連接されるとき角度２等分平面上に案内されるケージ窓を有するボールケージを含んでおり；第１外方軌道及び第１内方軌道が、前記内方継ぎ手部材の接続端部に向かって第１軸方向に広がりかつ第１ボールを保持する第１軌道対を形成し；第２外方軌道及び第２内方軌道が、前記外方継ぎ手部材の接続端部に向かって第２軸方向に広がりかつ第２ボールを保持する第２軌道対を形成し；前記角度２等分平面が、継ぎ手が連接されるとき前記外方継ぎ手部材と前記内方継ぎ手部材の軸線間の角度を対称的に分割する平面である、対向軌道継ぎ手の形における等速固定ボール継ぎ手に関するものである。
【０００２】
【従来の技術】
この型の継ぎ手は従来から知られている（例えば、特許文献１参照）。
【０００３】
【特許文献１】
独国特許出願公開第１００６０１１９．７−１２号明細書
【０００４】
【発明が解決しようとする課題】
この型の継ぎ手において、これまでは、ケージの外面が両軸方向において外方継ぎ手部材上に支持体を設けるための球状面を形成しかつケージの内面が軸方向の一方に内方部材を支持するための内方球状面を形成することが提案された。
【０００５】
ケージを軸方向に固定するために、外方継ぎ手部材はケージに軸方向に作用する別個の停止手段を備えている。環状形状において、前記停止手段が外方継ぎ手部材の開口端に固定されるならば、それらは継ぎ手の連接角度を制限し得る。停止手段が外方継ぎ手部材用の接続端に固定されるならば、組み立て後、外方継ぎ手部材に接続されねばならない別個の継ぎ手基部を設ける必要がある。
【０００６】
本発明の目的は、内方継ぎ手部材及び外方継ぎ手部材が相体的に実質上軸方向に整列される状態において組み立てられることができる対向軌道継ぎ手を提供することにある。
【０００７】
【課題を解決するための手段】
上記目的は、以下の特徴、すなわち、前記外方継ぎ手部材が前記内方継ぎ手部材の接続端部に向かって第１開口および前記外方継ぎ手部材の接続端部に向かって第２開口を含んでおり；前記外方継ぎ手部材が、前記外方継ぎ手部材の内側で、前記ボールケージが継ぎ手の組み立ての間中前記外方継ぎ手部材に対して軸方向に移動可能である軸方向移動面を形成し；前記外方継ぎ手部材が、前記外方継ぎ手部材の内側で、前記ボールケージの外面用の第１停止および案内面を形成し、その第１停止および案内面は前記第２軸方向に向かい合っており；前記外方継ぎ手部材に挿入される保持要素が前記ボールケージの外面用の追加の停止および案内面を形成し、その追加の停止および案内面が前記第１軸方向に向かい合っており；前記ボールケージが、前記ボールケージの内側で、前記内方継ぎ手部材の球状外面が継ぎ手の組み立ての間中軸方向に移動可能である案内面を形成し、その案内面が前記内方継ぎ手部材用の第３停止および案内面に変化し、その第３停止および案内面前記第２軸方向に向かって向かい合っており；継ぎ手を組み立てるために、前記保持要素が前記外方継ぎ手部材から解放されかつ前記外方継ぎ手部材の接続端に向かって前記第２軸方向に移動されそして、継ぎ手が組み立てられるとき、前記保持要素が遊びのない方法において前記ボールケージを軸方向に固定するために前記内方継ぎ手部材の前記接続端に向かって前記第１軸方向に移動されそして前記保持要素が前記内方継ぎ手部材に対して停止しかつ前記外方継ぎ手部材上に軸方向に支持されることを有する最初に述べた型の継ぎ手を設けることによって達成される。
【０００８】
組み立てのために、外方継ぎ手部材に対して同軸的に整列されるケージは前記外方継ぎ手部材の接続端に対して予め定めた領域内で軸方向に移動可能でなければならない。ボールが取り付けられた後、内方継ぎ手部材は前記外方継ぎ手部材の接続端から摺動されかつケージに導入され、外方継ぎ手部材内のケージの軸方向の移動通路は、内方軌道の最も高い点とともに、内方継ぎ手部材が、ボールを通って案内されるようにボールが外方軌道の最も深い領域に入ることができるように寸法付けられる。続いて、内方継ぎ手部材はこの内方継ぎ手部材の接続端に向かって反対方向に移動される。軸方向の固定は前記外方継ぎ手部材の接続端から保持要素を挿入することによって行われる。
【０００９】
外方継ぎ手部材は両端において開口を有する連続内部を形成する。ケージおよび内方継ぎ手部材はそれぞれ外方継ぎ手部材と一体であるように製造される第１停止および案内面によって内方継ぎ手部材の接続端に向かって支持され、その利点は、継ぎ手ジャーナルの連接運動が継ぎ手端で外方継ぎ手部材において環状保持要素によって制限されないということである。
【００１０】
好都合な実施の形態によれば、外方継ぎ手部材の軸方向移動面が第１停止および案内面から軸方向に少なくとも第２外方軌道の最も深い点まで延びることが提案される。軸方向の移動面は、好ましくは、軸方向の移動運動の間中遊びのない方法においてケージを案内することができるように内方で筒状である。
【００１１】
保持要素は、好ましくは、筒状スリーブがそれに取着される平らな基部を有する板状金属カバーの形で設けられる。さらに他の実施の形態によれば、保持要素が、外方継ぎ手部材の基部開口に軸方向に移動されることができ、前記第２開口が固定リングを挿入するための環状溝を含んでいることを提案することができる。
【００１２】
原則として、内方継ぎ手部材と保持要素は外方継ぎ手部材の接続端から外方継ぎ手部材の第２開口を通ってのみ外方継ぎ手部材に挿入されることができ、これに反して、ケージは内方継ぎ手部材用の接続から外方継ぎ手部材の第１開口を通ってのみ外方継ぎ手部材に導入されることができる。まず、ケージが、次いでボールが、次いで内方継ぎ手部材が取り付けられねばならない。
【００１３】
第１の可能性によれば、内方継ぎ手部材の球状外面がそれに一体であるように製造されることが提案される。第２の可能性によれば、内方継ぎ手部材は球状外面の中央部分を形成する別個のプラグを含むことが提案される。とくに好都合な方法において、本書で述べられる型の継ぎ手は、接続の強度を増大しかつ部品の数を減少しそして外方継ぎ手部材および内方継ぎ手部分の実質上軸方向の組み立てを許容する、一体に形成された継ぎ手ジャーナルを有する内方継ぎ手部材を含んでおり、継ぎ手が連接される必要はない。
【００１４】
結果として、ケージの窓の周部長さは運転の連接角度に必要とされる寸法に制限されることができ、その結果として、また、ケージの強度が増大される。ボールケージの外面は、好ましくは、球状である。とくに好都合なさらに他の実施の形態によれば、ベアリングが外方継ぎ手部材上に直接摺動され、ベアリングが内方継ぎ手部材の接続端から摺動されかつ外方継ぎ手部材において突起によって軸方向に固定される二重列のベアリングが提案される。
【００１５】
この方法において、継ぎ手とホイールハブはベアリングと一体にされ、固定継ぎ手接続において部品の数はしたがって減少される。突入継ぎ手に通じる中間軸の長さは増大され得る。好都合な支持運動を達成するために、ベアリングの２列のボールは、好ましくは、継ぎ手が整列された状態にあるとき、ボール中心を通って延びる平面の両側に位置決めされる。
【００１６】
外方継ぎ手部材がその接続端に向かって軸方向に深くされかつ組み立てのために、ケージが、一時的に深く入ることができる内部を含み、そしてボールと内方継ぎ手部材が取り付けられた後、ケージと内方継ぎ手部材が内方継ぎ手部材の接続端に向かう方向に移動されかつ保持要素によって軸方向に固定されることができるという特徴である。
【００１７】
さらに好都合な他の実施の形態によれば、第１軌道対が第１軌道対と反対に半径方向に配置されかつ第２軌道対が第２軌道対と反対に半径方向に配置されることが提案される。とくに、第１軌道対および第２軌道対が周部を横切って交互であるように配置されることが提案される。好ましくは、８個の均一に周部に分布された軌道対を有する継ぎ手が提案される。特定された手段はゼロから一定にずれるそれらのボール上の半径方向に対向の軌道対によって印加される結果として生じる制御力を達成する。この方法において、ケージ制御が改善される。
【００１８】
本発明の好適な実施の形態を以下の図面において例示する。
【００１９】
【発明の実施の形態】
図１および図２の２つの例示が以下で共同して説明される。外方継ぎ手部材１１は開口１３および対向する開口１４を備えた内部１２を含んでいる。接続ジャーナル１５は開口１４の側部において外方継ぎ手部材１１上に形成される。外方継ぎ手部材１１の突起４０によって軸方向に固定される転動接触ベアリング構体１７が外方継ぎ手部材１１上に位置決めされる。
【００２０】
そのうえ、それはベアリングにおいてフランジ環４１を識別することができる。内部１２には、開口１３から現れている一体に取着された軸ジャーナル２２を備えた内方継ぎ手部材２１が配置される。ボールケージ３１が外方継ぎ手部材１１と内方継ぎ手部材２１との間に位置決めされる。
【００２１】
そのうえ、中央ネジ３７によって軸方向に負荷される保持要素３５が開口１４に挿入される。継ぎ手は、継ぎ手中心から内方継ぎ手部材の接続端へ延びて第１の方向Ｒ１に向かって互いから遠ざかる第１外方軌道１６１および第１内方軌道２６１を含んでいる。そのうえ、継ぎ手は、継ぎ手中心から外方継ぎ手部材のジャーナル端へ向って延びて第２の方向Ｒ２に向かって互いから遠ざかる第２外方軌道１６２および第２内方軌道２６２を含んでいる。内方軌道および外方軌道から形成される軌道対はトルク伝達ボール３６１，３６２を収容する。ボールケージ３１は球状外面３２および球状の第３停止および案内面３９に変化する部分的に筒状内面３３を含んでいる。ボールはケージの窓３４に保持される。
【００２２】
その球状外面３２によって、ケージ３１は外方継ぎ手部材１１の第１停止および案内面１８に載置し、この第１停止および案内面１８は内方継ぎ手部材２１が第１の方向Ｒ１に移動されるのを阻止する。第１停止および案内面１８には、その内側でケージ３１が組み立ての間中軸方向に移動可能である内方に筒状の軸方向移動面１９が追随する。そのうえ、外方継ぎ手部材１１は、ケージ３１が第２の方向Ｒ２に移動されるのを阻止する第２停止および案内面２０を含んでいる。
【００２３】
内方継ぎ手部材２１は、第１の方向Ｒ１ への移動に対してボールケージ３１の第３停止および案内面３９に支持されかつ第２の方向Ｒ２ への移動に対して保持要素３５の追加の停止および案内面３８に支持される、大きい球状外面２３を含んでいる。保持要素は第１停止および案内面１８に対して軸方向に遊びのない方法において内方継ぎ手部材２１およびケージ３１を保持する。第１停止および案内面１８は外方軌道１６によって遮断される。
【００２４】
図３および図４の２つの例示が以下で共同して説明される。図３および図４は早期組み立て段階における図１による継ぎ手を示している。固定リングおよび保持要素は開口１４にまだ挿入されていない。ケージ３１は外方継ぎ手部材１１の軸方向の移動面１９に既に挿入されている。このために、ケージは、まず、横軸のまわりに９０°だけ回転されかつ次いで２つの外方軌道１６の間のウェブが窓３４の１つに通されることによって外方継ぎ手部材に開口１３から転動され、ケージ３１は次いで横軸のまわりに９０°だけ戻される場合に転動運動によって内部１２に導入され、その結果例示されたような位置を取る。ボール３６は内側から窓３４へと挿入されて保持される。
【００２５】
この同軸位置に配置されている外方継ぎ手部材１１およびケージ３１によって、隣接する軸ジャーナル２２を有する内方継ぎ手部材２１は、また、すでに同軸に配置されかつ部分的にケージ３１に導入される。軸方向の移動面１９内のケージ３１の軸方向の位置は第２停止および案内面２０の範囲まで右方に向かって移動される。
【００２６】
図５および図６の２つの例示が以下で共同して説明される。図５および図６において、内方継ぎ手部材２１は内部１２に向かう方法にさらに軸方向に移動される。ケージ３１は外方継ぎ手部材１１に対するその位置を取り続ける、すなわち、それは第２停止および案内面２０に載置している。
【００２７】
図７および図８の２つの例示は以下で共同して説明される。図７および図８において、内部１２に深く導入されている内方継ぎ手部材により、ボール３１は第２の方向Ｒ２に右方に向かって移動され、かつその球状外面３２によって、外方継ぎ手部材１１の第２停止および案内面２０に対して軸方向に載置しており、ボール３６２は外方軌道１６２の最も深い領域に入っている。
【００２８】
内方継ぎ手部材２１が左方に向かう第１の方向Ｒ１に導入されるとき内方軌道２６２の軌道基部の最も高い点をボールが克服できるように、ケージ３１は、軸方向移動面１９内で、ボール３６２が外方軌道１６２の最も深い点に達することができるような範囲に右方に向かって一時的に移動される必要がある。これは、継ぎ手を組み立てるために外方継ぎ手部材１１の軸方向移動面１９のケージ３１の軸方向の移動性の必要を説明する。
【００２９】
図９および図１０の２つの例示が以下で共同して説明される。図９および図１０は、ケージ３１が組み立てのために必要であるように第２の方向Ｒ２に移動された後に、ケージ３１が、外面３２が環状の第１停止および案内面１８に対して載置されかつ第１停止および案内面１８に対して遊びのない方法においてケージを軸方向に固定するような範囲で第１方向Ｒ１に左方に向かって第２停止および案内面２０から移動されることによって、ケージ３１が再び第１停止および案内面１８に対してどのように載置されるかを示している。内方継ぎ手部材２１はボール３６１，３６２が各々関連のボール軌道１６１，２６１，１６２，２６２と接触することができかつ球状外面２３がボールケージ３１の第３停止および案内面３９に対して載置するような範囲に同一の方向Ｒ１に左方に向かって外方継ぎ手部材１１において移動された。
【００３０】
保持要素３５および固定リング３７を挿入することによって、図１による仕上げ−組み立て継ぎ手が得られる。
【００３１】
図１１および図１２の２つの例示が以下で共同して説明される。図１１および図１２において、図１に示された詳細と同一の詳細が同一の参照番号を付与されている。その範囲で、図１の説明が参照される。内方継ぎ手部材２１は、また、軸ジャーナル２２と一体であるように製造されかつ環状の球状外面２３'を形成する。補完の中央の球状外面２３''を形成するプラグ３０は中央開口２９に挿入された。前記球状外面２３''は保持要素３５と直接接触している。
【００３２】
図１３および図１４の例示は以下で共同して説明される。軸方向図は、外方継ぎ手部材１１、内方継ぎ手部材２１、およびそれらの間の、ボール３６を有するケージ３１を示している。３つのフランジ環１５が外方継ぎ手部材上に形成される。交互に周部に分布された、継ぎ手開口に向かって広くなる第１軌道対１６１，２６１および継ぎ手開口に向かって狭くなる第２軌道対１６２，２６２を識別することができる。
【００３３】
８個の軌道対が設けられるならば、第１の軌道対は互いに対で半径方向に反対に位置決めされかつ第２の軌道対は互いに次いで半径方向に反対に位置決めされる。屈曲された断面平面Ａ−Ａによれば、長手方向断面図は第１軌道対１６１，２６１および第２軌道対１６２，２６２を示している。他の方法では、同一の図２の説明および参照番号が参照される。
【００３４】

BACKGROUND OF THE INVENTION
  The present invention provides an outer joint member having an outer track, an inner joint member having an inner track, a torque transmission ball housed in a track pair including the outer track and the inner track, and the ball Includes a ball cage having a cage window that is held in a common plane and the ball is guided on an angle bisector plane when the joint is articulated.;First outer orbitas well asFirst inward trajectoryBut,Toward the connecting end of the inner joint memberWide in the first axis directionAnd a first track pair holding the first ball; a second outer trackas well asSecond inward trajectoryBut,Toward the connecting end of the outer joint memberWide in the second axis directionThe angle bisection plane symmetrically defines the angle between the axis of the outer joint member and the inner joint member when the joint is articulated. The present invention relates to a constant velocity fixed ball joint in the form of an opposing track joint, which is a plane to be divided.
[0002]
[Prior art]
  This type of joint is conventionally known (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
German Patent Application Publication No. 100601119.7-12
[0004]
[Problems to be solved by the invention]
  In this type of joint, so far, the outer surface of the cage forms a spherical surface for providing a support on the outer joint member in both axial directions, and the inner surface of the cage supports the inner member on one of the axial directions. It has been proposed to form an inner spherical surface for this purpose.
[0005]
  To secure the cage in the axial direction, the outer joint member is provided with a separate stop means acting axially on the cage. In an annular shape, if the stop means are secured to the open end of the outer joint member, they can limit the articulation angle of the joint. If the stop means is secured to the connection end for the outer joint member, it is necessary to provide a separate joint base that must be connected to the outer joint member after assembly.
[0006]
  The purpose of the present invention is to, InsideJoint memberas well asThe outer joint memberphasePhysicallyPracticallyThe object is to provide an opposing track joint that can be assembled in an axially aligned state.
[0007]
[Means for Solving the Problems]
  The object includes the following features: the outer joint member includes a first opening toward the connection end of the inner joint member and a second opening toward the connection end of the outer joint member. There;in frontThe outer joint member isInside the outer joint member,The ball cage forms an axially moving surface that is axially movable relative to the outer joint member during assembly of the joint;in frontThe outer joint member, Inside the outer joint member,Forming a first stop and guide surface for the outer surface of the ball cage, the first stop and guide surface facing the second axial direction; a retaining element inserted into the outer joint member is the ball cage; For the exteriorAdditionalForming stop and guide surface, itsAdditionalThe stop and guide surfaces face each other in the first axial direction;Inside the ball cage,The spherical outer surface of the inner joint member forms a guide surface that is movable in the axial direction during assembly of the joint, and the guide surface is a second surface for the inner joint member.3 stopsChange to stop and guide surface,3 stopsStop and guide surfaces facing towards the second axis; for assembling the joint, the holding element is released from the outer joint member and towards the connecting end of the outer joint member When the coupling is assembled, the retaining element is moved in the first axial direction toward the connecting end of the inner coupling member to axially fix the ball cage in a play-free manner. This is achieved by providing a joint of the first mentioned type that is moved and the holding element stops against the inner joint member and is axially supported on the outer joint member.
[0008]
  For assembly, the cage that is coaxially aligned with the outer joint member must be axially movable within a predetermined area relative to the connecting end of the outer joint member. After the ball is installed, the inner joint member is slid from the connecting end of the outer joint member and introduced into the cage, and the axial movement path of the cage within the outer joint member is the most of the inner track. Along with the high point, the inner joint member is dimensioned to allow the ball to enter the deepest region of the outer track so that it is guided through the ball. Subsequently, the inner joint member is moved in the opposite direction toward the connecting end of the inner joint member. The axial fixing is performed by inserting a holding element from the connecting end of the outer joint member.
[0009]
  The outer joint member forms a continuous interior with openings at both ends. The cage and the inner joint member are each manufactured in one piece with the outer joint member.1 stopSupported by the stop and guide surfaces towards the connecting end of the inner joint member, the advantage is that the articulation movement of the joint journal is not limited by the annular retaining element at the joint end at the outer joint member.
[0010]
  According to an advantageous embodiment, the axial movement surface of the outer joint member is1 stopIt is proposed to extend from the stop and guide surface in the axial direction to at least the deepest point of the second outer track. The axial movement surface is preferably cylindrical inward so that the cage can be guided in a play-free manner during the axial movement movement.
[0011]
  The holding element is preferably provided in the form of a sheet metal cover having a flat base to which the cylindrical sleeve is attached. According to yet another embodiment, the holding element can be moved axially into the base opening of the outer joint member, said second opening including an annular groove for inserting a fixing ring. Can be proposed.
[0012]
  In principle, the inner joint member and the holding element can only be inserted into the outer joint member from the connecting end of the outer joint member through the second opening of the outer joint member, whereas the cage is It can only be introduced into the outer joint member from the connection for the inner joint member through the first opening of the outer joint member. First, the cage, then the ballBut,The inner joint member must then be attached.
[0013]
  According to a first possibility, it is proposed that the spherical outer surface of the inner joint member is manufactured so as to be integral therewith. According to a second possibility, it is proposed that the inner joint member comprises a separate plug forming the central part of the spherical outer surface. In a particularly advantageous manner, the type of joint described herein is an integral piece that increases the strength of the connection and reduces the number of parts and allows for substantially axial assembly of the outer and inner joint parts. And includes an inner joint member having a joint journal formed thereon, and the joint need not be articulated.
[0014]
  As a result, the peripheral length of the cage window can be limited to the dimensions required for the articulation angle of operation, and as a result, the strength of the cage is also increased. The outer surface of the ball cage is preferably spherical. According to yet another particularly advantageous embodiment, the bearing is slid directly on the outer joint member, the bearing is slid from the connecting end of the inner joint member and axially by a protrusion on the outer joint member. A fixed double row bearing is proposed.
[0015]
  In this way, the joint and wheel hub are integrated with the bearing and the number of parts is thus reduced in the fixed joint connection. The length of the intermediate shaft leading to the plunge joint can be increased. In order to achieve a convenient support movement, the two rows of balls in the bearing are preferably positioned on either side of a plane extending through the ball center when the joint is in alignment.
[0016]
  After the outer joint member is deepened axially towards its connecting end and for assembly, the cage includes an interior that can be temporarily deeply inserted, and after the ball and the inner joint member are attached, It is a feature that the cage and the inner joint member can be moved in a direction toward the connection end of the inner joint member and can be fixed in the axial direction by the holding element.
[0017]
  furtherAccording to another advantageous embodiment, it is proposed that the first track pair is arranged radially opposite to the first track pair and the second track pair is arranged radially opposite to the second track pair. Is done. In particular, it is proposed that the first track pair and the second track pair are arranged so as to alternate across the circumference. Preferably, a joint with 8 uniformly distributed circumferentially distributed track pairs is proposed. The identified means achieves the resulting control force applied by a radially opposed pair of trajectories on those balls that deviate from zero. In this way, cage control is improved.
[0018]
  Preferred embodiments of the invention are illustrated in the following drawings.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
  The two illustrations of FIGS. 1 and 2 are jointly described below. Outer joint member 11 is open 13 and oppositeDoAn interior 12 with an opening 14 is included. The connection journal 15 is formed on the outer joint member 11 at the side of the opening 14.
