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、外方継ぎ手部材と内方継ぎ手部材が、実質上、軸方向に取り付けられ得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、
その内側で、前記外方継ぎ手部材が、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；
その内側で、前記外方継ぎ手部材が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第２停止および案内面を形成し、その第２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；
その内側で、前記ボールケージが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；
継ぎ手の組み立てのために、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ボールケージ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によって達成される。
【０００８】
好都合な実施の形態によれば、前記外方継ぎ手部材の前記軸方向移動面が少なくとも前記第２外方軌道の最も深い領域まで前記第１停止および案内面から軸方向に延びることが提案される。前記軸方向移動面は、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に筒状である。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、外方継ぎ手部材の予め定められた領域内に軸方向に移動されることができる。
【０００９】
内方継ぎ手部材は、ボールがケージに取り付けられかつケージの内側から外方軌道に挿入されるようなボールを許容するように十分に離して外方継ぎ手部材の接続端に向かって押される前にケージに導入される。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。外方継ぎ手部材の内側のケージの軸方向移動通路は、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。
【００１０】
軸方向組み立ては、内方継ぎ手部材が、組み立てのために、外方継ぎ手部材の内部に深く導入されたとき、保持要素の後で、内方継ぎ手部材の接続端に向かって保持要素を移動することによって行われる。外方継ぎ手部材は組み立ての間中保持要素を収容する深くされた内部を形成することができる。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に一体に設けられる第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る。この実施の形態の利点は、継ぎ手ジャーナルの連接運動が内方継ぎ手部材の接続端で外方継ぎ手部材において保持要素によって制限されないということである。
【００１１】
非常に好都合な方法において、ここで記載される型の継ぎ手は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むことができ、その結果として接続の強度は増加されかつ部品の数が減少される。これは、順次、継ぎ手が実質上軸方向に取り付けられるのを許容し、そこに継ぎ手が連接される必要がない。結果として、ケージの窓の周部長さは、また、ケージの強度を増大する、運転の連接角度に必要とされる寸法に制限される。
【００１２】
好適な実施の形態において、保持要素は、外方軌道間に位置決めされながら、ボールケージの球状外面と協働する、個々の指部が取着される厚い板状金属カバーの形で設けられる。一体に形成された基部により、保持要素は軸方向の調整ネジによって基部に軸方向に固定され得る。さらに他の実施の形態によれば、保持要素は、圧縮された状態において、外方継ぎ手部材の基部開口に押し込まれることができかつ半径方向に緊張されない状態において、外方継ぎ手部材の環状縁部に支持される弾力のある環状カラーを含むことができる。
【００１３】
さらに他の実施の形態によれば、保持要素は外方継ぎ手部材の基部開口に軸方向に移動され得る筒状部分を含むことが提案され、前記基部開口は固定リングを挿入するための環状溝を含んでいる。さらに他の好適な実施の形態によれば、保持要素は、外方継ぎ手部材の基部上に弾力的に支持される板ばね状中央領域を備えることができる。
【００１４】
強度のために、外方継ぎ手部材は、その接続端において、一体に形成された基部を備えることができる。原則として、保持要素は内方継ぎ手部材の接続端から外方継ぎ手部材の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る。同じように、ケージと内方継ぎ手部材は内方継ぎ手部材用の接続端から外方継ぎ手部材の開口を通ってのみ外方継ぎ手部材に実質上同軸的に挿入されることができる。
【００１５】
ケージが内方継ぎ手部材用の純粋に筒状の案内面を含むかまたは内方継ぎ手部材の接続端に向いているその側で、ケージが内方に向かって引き込まれているかどうかに依存して、まず、ケージかつ次いで内方継ぎ手部材に関して、または、まず、内方継ぎ手部材に関してかつ次いでケージに関して取り付けられることが必要である。ケージの外面は好ましくは形状において球状である。
【００１６】
とくに好都合な実施の形態によれば、ベアリング手段が前記外方継ぎ手部材上に直接摺動され、前記ベアリング手段が前記内方継ぎ手部材の接続端から二重列ベアリングの形において摺動され、一方、前記外方継ぎ手部材上に突起によって軸方向に固定されている。この方法において、継ぎ手およびホイールハブはベアリングと一体にされる。固定継ぎ手を接続するのに必要とされる部品の数はかくして減少される。緩い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。
【００１７】
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、保持要素および内方継ぎ手部材ならびにケージが、一時的に深く入ることができる内部を含み、そしてボールが取り付けられた後、ケージと保持要素が内方継ぎ手部材の接続端に向かって移動されかつ軸方向に固定されることができる。
【００１８】
好都合な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。
【００１９】
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。
【００２０】
【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を備えた内部１２および反対端に向かって内部１２を閉止する対向基部１４を含んでいる。接続ジャーナル１５は基部１４の端部において外方継ぎ手部材１１上に形成される。外方継ぎ手部材にはこの外方継ぎ手部材の突起４０を介して軸方向に固定される転動接触ベアリング構体１７が位置決めされる。内部１２には、開口１３から現れている一体に形成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。外方継ぎ手部材１１と内方継ぎ手部材２１との間には、ボールケージ３１が位置決めされる。
【００２１】
そのうえ、中央ネジ３７によって軸方向に配置される保持要素３５が内部に挿入される。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。トルク伝達ボール３６１，３６２は内方軌道および外方軌道から形成される軌道対に配置される。ボールケージ３１は球状外面３２および筒状内面３３を含んでいる。ボールはケージ３１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。停止面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、順次、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３８を形成する環状保持要素３５用の内方に筒状の移動面２０を含んでいる。前記第２停止および案内面３８は第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３１を軸方向に保持する。
【００２３】
停止および案内面１８は外方軌道１６によって遮断される。停止および案内面３８は保持要素の個々の指部に設けられ、その指部は外方軌道１６間に達する。このために、保持要素３５は外方継ぎ手部材１１に螺入されるネジ３７によって第１の方向Ｒ1に移動面２０内で軸方向に移動される。
【００２４】
図３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。ネジは基部１４から外され、その結果移動面２０において保持要素３５は右方に向かって移動されている。ケージ３１は、保持要素３５が開口１３から外方継ぎ手部材１１に挿入されるとき外方継ぎ手部材１１の軸方向の移動面１９に既に挿入されている。
【００２５】
ケージ３１を挿入するために、ケージは、まず、横軸のまわりに９０°だけ回転されかつ２つの外方軌道１６の間のウェブを窓３４の１つに通すことによって外方継ぎ手部材に転動されねばならず；転動運動によって、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。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の軸方向の位置は重要ではない。
【００２６】
図４において、内方継ぎ手部材２１は内部１２にさらに軸方向に導入されかつ角度によりそれに対して連接される。ケージ３１は外方継ぎ手部材１１に対してその同軸の位置に保持し続ける。第１のボール３６2はケージ３１の窓３４の１つに内側から開口１３を通って導入されている過程にある。
【００２７】
図５は、ところで、内部１２に深く導入されている内方継ぎ手部材２１により、すべてのボールが取り付けられた、すなわち、それらが内側からケージ窓３４に挿入されかつ外方軌道１６1，１６2に係合することを示している。軸方向の移動面１９内のケージ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、また、第２の方向Ｒ2に右方に向かって移動される保持要素の第２停止および案内面３８に対して軸方向に載置しており、ボールは外方軌道２６1，２６2にすでに部分的に入っている。
【００２８】
左方に向かう第１の方向Ｒ1における内方継ぎ手部材２１の戻り運動の間中内方軌道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、ケージは、案内面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案内面１９内でのケージの軸方向の移動性を説明する必要がある。
【００２９】
図６は、ケージが組み立てのために軸方向に移動された後に、ケージが、ネジ３７が螺入されかつ案内面２０において保持要素３５が、環状の第２停止および案内面３８が第１停止および案内面１８に対してケージを、遊びのない方法において、軸方向に固定するような範囲に左方に向かって第１方向Ｒ1に移動されることによって第１停止および案内面１８に対して再び載置するようにどのようになされたかを示している。内方継ぎ手部材２１はボール３６1，３６2がそれらの関連のボール軌道１６1，２６1，１６2，２６2と接触することができるのに十分離して外方継ぎ手部材１１から引き出された。
【００３０】
図７および図８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備えている。その範囲で、図１の説明が参照される。保持要素３５は−例示されたような取り付けられた状態において−外方継ぎ手部材１１の内方縁部２４上に支持される半径方向に弾力のあるカラー３９を含んでいる。前記内方縁部２４には、軸方向の組み立てのために、半径方向に圧縮されたリング３９をその中に押圧することができる筒状の基部開口２５が追随する。
【００３１】
図９および図１０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備えている。その範囲で、図１の説明が参照される。この場合に、保持要素３５は筒状基部開口２５内に軸方向に移動可能である皿形状の基部部分４２を含んでいる。基部開口２５は固定リング２８がそこに固定されかつ保持要素３５を軸方向に固定するのに役立つ環状溝２７を含んでいる。
【００３２】
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備えている。その範囲で、図１の説明が参照される。図１１および図１２は、保持要素３５が、外方継ぎ手部材１１の基部１４上に弾力的に支持される、半径方向に弾力のある、板ばね状指部４３を含むことによって図１からずれている。
【００３３】
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。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が交互に周部に配置されて設けられる。
【００３４】
８個の軌道対が設けられるならば、第１の軌道対は互いに半径方向に反対に半径方向位置されかつ第２の軌道対は互いに半径方向に反対に配置される。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１１の説明および参照番号が参照される。
【００３５】

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]
An object of the present invention is to provide an opposed track joint in which an outer joint member and an inner joint member can be mounted substantially in the axial direction.
[0007]
[Means for Solving the Problems]
The above objective has the following characteristics:
On the inside thereof, the outer joint member forms an axial movement surface in which the ball cage is axially movable relative to the outer joint member during assembly of the joint;
Inside, the outer joint member forms 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 holding element inserted into the outer joint member forms a second stop and guide surface for the outer surface of the ball cage, the second stop and guide surface facing the first axial direction;
On the inside, the ball cage forms a guide surface in which the spherical outer surface of the inner joint member is movable axially during assembly of the joint;
For assembly of the joint, the retaining element is released from the outer joint member and moved in the second axial direction towards the connecting end of the outer joint member and when the joint is assembled, the retaining element Is moved in the first axial direction towards the connecting end of the inner joint member to axially fix the ball cage in a play-free manner and the retaining element stops against the ball cage And is achieved by a joint of the first mentioned type having an axial support on said outer joint member.
[0008]
According to an advantageous embodiment, it is proposed that the axial movement surface of the outer joint member extends axially from the first stop and guide surface to at least the deepest region 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. For assembly, the cage that is coaxially aligned with the outer joint member can be moved axially into a predetermined region of the outer joint member.
[0009]
Before the inner joint member is pushed towards the connecting end of the outer joint member sufficiently far away to allow the ball to be attached to the cage and inserted into the outer track from the inside of the cage Introduced into the cage. Subsequently, the inner joint member is moved in the opposite direction toward the connecting end of the inner joint member. The axial movement path of the cage inside the outer joint member, together with the highest point of the inner track, the inner joint member
Dimensioned to allow the ball to enter the deepest region of the outer track so that it can be guided through the ball.
[0010]
Axial assembly moves the retaining element after the retaining element toward the connecting end of the inner coupling member when the inner coupling member is introduced deep inside the outer coupling member for assembly. Is done by. The outer joint member can form a deepened interior that receives the retaining element during assembly. The cage and the inner joint member are respectively supported toward the connection end of the inner joint member by a first stop and guide surface provided integrally with the outer joint member. The advantage of this embodiment is that the articulation movement of the joint journal is not limited by the holding element at the outer joint member at the connection end of the inner joint member.
[0011]
In a highly convenient manner, the type of joint described herein can include an inner joint member having an integrally formed joint journal so that the strength of the connection is increased and the number of parts is reduced. Is done. This in turn allows the joint to be mounted substantially axially, without the joint need to be articulated there. As a result, the circumferential length of the cage window is also limited to the dimensions required for the articulation angle of operation, which increases the strength of the cage.
[0012]
In a preferred embodiment, the holding element is provided in the form of a thick plate-like metal cover to which the individual fingers are attached, cooperating with the spherical outer surface of the ball cage while being positioned between the outer tracks. With the integrally formed base, the holding element can be axially fixed to the base by means of an axial adjustment screw. According to yet another embodiment, the retaining element can be pushed into the base opening of the outer joint member in the compressed state and, in the non-radially tensioned state, the annular edge of the outer joint member Can include a resilient annular collar supported on the surface.
[0013]
According to a further embodiment, it is proposed that the holding element comprises a cylindrical part that can be moved axially in the base opening of the outer joint member, said base opening being an annular groove for inserting a fixing ring Is included. According to yet another preferred embodiment, the retaining element can comprise a leaf spring-like central region that is resiliently supported on the base of the outer joint member.
[0014]
For strength, the outer joint member can have an integrally formed base at its connecting end. In principle, the holding element can only be inserted into the outer joint member from the connection end of the inner joint member through the opening of the outer joint member. Similarly, the cage and inner joint member can be inserted substantially coaxially into the outer joint member only from the connection end for the inner joint member through the opening in the outer joint member.
[0015]
Depending on whether the cage is retracted inward on the side where the cage includes a purely cylindrical guide surface for the inner joint member or towards the connecting end of the inner joint member First, it needs to be attached with respect to the cage and then with respect to the inner joint member, or first with respect to the inner joint member and then with respect to the cage. The outer surface of the cage is preferably spherical in shape.
[0016]
According to a particularly advantageous embodiment, bearing means are slid directly on the outer joint member, the bearing means being slid in the form of a double row bearing from the connecting end of the inner joint member, , And are axially fixed by protrusions on the outer joint member. In this way, the joint and wheel hub are integrated with the bearing. The number of parts required to connect the fixed joint is thus reduced. The length of the intermediate shaft leading to the loose 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.
[0017]
The outer joint member is deepened axially towards its connecting end and, for assembly, the retaining element and the inner joint member and the cage include an interior that can be temporarily inserted deeply, and a ball is attached After that, the cage and the retaining element can be moved towards the connecting end of the inner joint member and fixed axially.
[0018]
According to an 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. . 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.
[0019]
Preferred embodiments of the invention are illustrated in the following drawings.
[0020]

The two illustrations of FIGS. 1 and 2 are jointly described below. Outer joint member 11 includes an interior 12 with an opening 13 and an opposing base 14 that closes the interior 12 toward the opposite end. The connection journal 15 is formed on the outer joint member 11 at the end of the base portion 14. A rolling contact bearing assembly 17 fixed in the axial direction is positioned on the outer joint member via the projection 40 of the outer joint member. Arranged in the interior 12 is an inner joint member 21 with an integrally formed shaft journal 22 emerging from the opening 13. A ball cage 31 is positioned between the outer joint member 11 and the inner joint member 21.
[0021]
  In addition, the holding element 35 arranged in the axial direction by the central screw 37 is inserted inside. The joint extends from the joint center to the connection end of the inner joint memberTheFirst direction R1InHeadingEach otherMove away fromFirst outer orbit 161And the first inward track 261Is included. In addition, the joint extends from the center of the joint toward the journal end of the outer joint member.TheSecond direction R2InHeadingEach otherMove away fromSecond outer orbit 162And the second inward orbit 262Is included. Torque transmission ball 361, 362Are arranged in a track pair formed by an inner track and an outer track. The ball cage 31 includes a spherical outer surface 32 and a cylindrical inner surface 33. The ball is held in the window 34 of the cage 31.
[0022]
Due to the spherical outer surface 32, the cage 31 rests on the first stop and guide surface 18 of the outer joint member 11, and the first stop and guide surface 18 has the inner joint member 21 in the first direction R.1To be moved to. A cylindrical axial movement surface 19 follows the stop surface 18 inwardly so that the cage 31 can move in the middle axial direction during assembly. In addition, the outer joint member 11 has the cage 31 in the second direction R in turn.2A cylindrical moving surface 20 is included inwardly for the annular holding element 35 which forms a second stop and guide surface 38 which prevents it from being moved. The second stop and guide surface 38 holds the cage 31 axially in a manner that is free of play relative to the first stop and guide surface 18.
[0023]
The stop and guide surface 18 is interrupted by the outer track 16. Stop and guide surfaces 38 are provided on the individual fingers of the holding element, which fingers reach between the outer tracks 16.

To insert the cage 31, the cage is first rotated by 90 ° about the transverse axis and rolled into the outer joint member by passing the web between the two outer tracks 16 through one of the windows 34. By rolling motion, the cage 31 is then introduced into the interior 12 when it is returned by 90 ° around the transverse axis, resulting in a position as illustrated. By means of the outer joint member 11 and the cage 31 arranged in a coaxial position, the inner joint member 21 with the adjacent axial journal 22 is also already arranged coaxially and partly introduced into the cage 31. The axial position of the cage 31 within the axial movement surface 19 is not critical.
[0026]
In FIG. 4, the inner joint member 21 is further introduced axially into the interior 12 and is connected thereto by an angle. The cage 31 continues to be held at its coaxial position with respect to the outer joint member 11. First ball 362Is in the process of being introduced into one of the windows 34 of the cage 31 through the opening 13 from the inside.
[0027]

This is necessary to account for the axial mobility of the cage within the guide surface 19 in order to assemble the joint.
[0029]
FIG. 6 shows that after the cage has been moved axially for assembly, the cage is screwed with screws 37 and the retaining element 35 on the guide surface 20 is the second stop and the guide surface 38 is the first stop. And the first direction R toward the left in such a range that the cage is fixed axially in a play-free manner with respect to the guide surface 18.1It is shown how it was made to mount again on the first stop and guide surface 18 by being moved to. The inner joint member 21 is a ball 36.1, 362Are their associated ball trajectories 161, 261, 162, 262However, it was pulled out from the outer joint member 11 with sufficient separation.
