Description

【0001】
【産業上の利用分野】
本発明は、例えば自動車の懸架装置及び操舵装置等に使用されるボールジョイントとアームとの結合構造に関する。
【0002】
【従来の技術】
従来より自動車の懸架装置や操舵装置の連結部は、ボールジョイントとアームとの結合により連結されることが多くあった。このようなボールジョイントとアームとの結合構造には図5に示される如きものがある。ボールジョイント101は、球状の球頭部105と球頭部105から延出する柄部103とを有するボールスタッド102と、ボールスタッド102の球頭部105を揺動回動自在に包持し、一端に開口107を有し、内側に潤滑剤が塗布されている合成樹脂製のベアリング106と、そのベアリング106を内包し一方にその内周からボールスタッド102の柄部103を突出させる小開口109を、他方に大開口110を有するハウジング108と、ハウジング108大開口110端部にかしめ固定される円盤状の閉止板112とを有していた。またアーム131は、円筒部132と円筒部132から軸線垂直方向に延出する延出部133とよりなり、アーム131の円筒部132内周にボールジョイント101のハウジング108が圧入され、更にボールスタッド102の柄部103に他部品(図示せず)が嵌合されて、ボールジョイント101がアーム131と他部品とを連結していた。
【0003】
上記ボールジョイント101に関し、閉止板112のハウジング108への固定状態を詳細に説明する。ハウジング108の内周は、ベアリング106の外周面と略同形状の小径部108aと、小径部108aより大径で大開口110を形成する大径部108cと、小径部108aと大径部108cとを繋いで軸線垂直方向に延びる水平部108bとよりなる。閉止板112はハウジング108の大開口110内周に配置された後、ハウジング108の大径部108cが内側にかしめ成形され、閉止板112が水平部109bにつきあてられた状態でハウジング108の大開口110内周にかしめ固定される。このときベアリング106はハウジング108の小径部108aより軸線方向長が若干長く形成されているため、閉止板112がハウジング108の大開口110内周にかしめ固定されることによりベアリング106がハウジング108の小開口109側に押圧されて若干軸線方向長が短縮され、所定の予圧を受けた状態になっていた。
【0004】
【発明が解決しようとする課題】
上記の如きボールジョイント101において、突発的に軸線方向の大きな荷重がボールジョイント101にかかることがある。そのようなときに、特にその荷重により閉止板112が反球頭部側に押された場合、ハウジング108のかしめ部分が緩み閉止板112が反球頭部側へ移動してハウジング108の水平部108bと閉止板112との間に隙間が生じることがある。すると、ベアリング106がその隙間により軸線方向の移動が可能となるため、ガタが発生するということがあった。また、ベアリング106に所定の予圧がかからなくなるため、ボールスタッド102のトルクが変動してしまうということが考えられる。さらに、ハウジング108の緩んだかしめ部分から潤滑剤が漏出して、ボールスタッド102の球頭部105とベアリング106との間の潤滑性が維持できなくなるということも考えられる。
【0005】
従って、本発明は上記の如き課題を解決し、軸線方向の耐荷重性が高いボールジョイントとアームとの結合構造を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明の構成は以下の通りである。
【0007】
球状の球頭部と球頭部から突出する柄部とよりなるボールスタッドと、ボールスタッドの球頭部を揺動回動自在に包持し、一方に開口を有するベアリングと、ベアリングを内包し、一方にボールスタッドの柄部を突出させる小開口を、他方に大開口を有するハウジングと、ハウジングの大開口を閉塞する閉止板とを有するボールジョイントと、ボールジョイントのハウジングが挿入され、両端に開口を有する円筒部と、円筒部から延びる延出部とを有するアームとの結合構造において、ボールジョイントのハウジングは、大開口側外周につば部が形成され、閉止板はハウジングのつば部に倣った形状のかしめ部を有し、かしめ部は、ハウジングの大開口を塞ぐ閉止板の閉塞部から連続しハウジングの小開口側に延びる中間かしめ部と、中間かしめ部から連続し内側に折曲するかしめテール部とよりなり、かしめ部のかしめテール部はハウジングのつば部とアームの円筒部との間で挟持される。
【0008】
【実施例】
以下、本発明の実施例を図1乃至図4を基に説明する。
【0009】
図1に示されるのは本発明の実施例によるボールジョイント1とアーム31との結合構造である。このボールジョイント1は、球状の球頭部5と球頭部5から突出し反球頭部側端部に螺子部4を有する柄部3とからなるボールスタッド2と、ボールスタッド2の球頭部5を揺動回動自在に内包し一方に開口7を有し、内側に潤滑剤が塗布される合成樹脂製のベアリング6と、ベアリング6を包持する略円筒状のハウジング8とを有する。ハウジング8は、一方にボールスタッド2の柄部3を突出させる小開口9、他方に外側に延出する周状のつば部11が外周に形成された大開口10を有している。閉止板12は外周端部をかしめられることによりハウジング8のつば部11に固定されている。また17はダストカバーで、内側に断面略L字状のL字環20が埋設されたダストカバー小開口部18がボールスタッド2の柄部3外周に、内側に補強環21が埋設されたダストカバー大開口部14がハウジング8の小開口9外周に各々装着される。
【0010】
上記ボールジョイント1の閉止板12について詳細に説明する。閉止板12はハウジング8の大開口9を閉塞しハウジング9のつば部11外径とより若干大径の閉塞部13と、閉塞部13から連続しハウジング8の小開口9側に延出する中間かしめ部15と、中間かしめ部15から連続し内側に延出するかしめテール部16とよりなり、中間かしめ部15とかしめテール部16からかしめ部14が構成される。
【0011】
また、アーム31は、ハウジング8より若干小径の内径を有する円筒部32と、円筒部32から軸線垂直方向に延出する延出部33とよりなる。
【0012】
続いて上記ボールジョイント1の組立方法を図2乃至図3を基に説明する。
【0013】
図2に示されるのは、ボールジョイント1の第一予備組立体1aとかしめ前の予備閉止板12aである。第一予備組立体1aは、ボールスタッド2の球頭部5にベアリング6が嵌装された状態でボールスタッド2の柄部3からハウジング8内へ圧入して組立てられている。予備閉止板12aは、ハウジング8のつば部11外径と略同径の内径が形成される円筒状の壁部14aを備え、一方に閉止板開口15a、他方に閉止板底部である閉塞部13を有する略カップ形状である。この予備閉止板12a内に第一予備組立体1aを配置して、図3に示す如き第二予備組立体1bを組立てる。続いて、この予備閉止板12aの壁部14aの閉止板開口15a側端部をハウジング8のつば部11形状に倣って内側にかしめ成形し、図4に示す如き第三予備組立体1cを組立てる。このとき予備閉止板12aの壁部14aは、閉塞部13から連続して軸線方向に延びる中間かしめ部15と中間かしめ部の閉止板開口15a側端部から内側に折曲するかしめテール部16とからなるかしめ部14に成形され、閉止板12となる。
【0014】
次にこの第三予備組立体1cを、図4に示す如くボールスタッド2の柄部3側からアーム31の円筒部32内に圧入し、第三予備組立体1cとアームと31を連結する。このとき閉止板12のかしめテール部16はアーム31の円筒部32端面に当接し、これにより閉止板12のかしめテール部16はアーム31の円筒部32とハウジング8のつば部11との間に挟持される。最後にダストカバー17をボールスタッド2の柄部3から圧入し、図1に示す如く、小開口部18をボールスタッド2の柄部3外周に、大開口部19をハウジング8の小開口9外周に各々装着して、ボールジョイント1とアーム31との組立ては完了する。
【0015】
よって、上記の如く組立てられるボールジョイント1とアーム31との結合構造によれば、閉止板12のかしめテール部16がハウジング8のつば部11とアーム31の円筒部32との間に挟持されているので、ボールジョイント1の軸線方向に強い荷重がかかっても閉止板12が移動することなく所定の位置に維持される。
【0016】
なお、上記実施例では閉止板13のかしめ成形前の形状は、ハウジング8のつば部11外径と略同径の内径が形成される壁部14aを備え、一方に閉止板開口15a、他方に閉止板底部である閉塞部13を有し、閉塞部13により他方が塞がれる円筒形であったが、その形状に限定されるものではない。つまり、円盤状の閉止板をまずハウジングのつば部の位置から軸線方向ハウジング側に折曲し、その後上記実施例と同様に内側に折曲してもよい。
【0017】
【発明の効果】
以上のように本発明によれば、球状の球頭部と球頭部から突出する柄部とよりなるボールスタッドと、ボールスタッドの球頭部を揺動回動自在に包持し、一方に開口を有するベアリングと、ベアリングを内包し、一方にボールスタッドの柄部を突出させる小開口を、他方に大開口を有するハウジングと、ハウジングの大開口を閉塞する閉止板とよりなるボールジョイントと、ボールジョイントのハウジングが挿入され、両端に開口を有する円筒部と、円筒部から延びる延出部とを有するアームとの結合構造において、ボールジョイントのハウジングは、大開口側外周につば部が形成され、閉止板はハウジングのつば部に倣った形状のかしめ部を有し、かしめ部は、ハウジングの大開口を塞ぐ閉止板の閉塞部から連続しハウジングの小開口側に延びる中間かしめ部と、中間かしめ部から連続し内側に折曲するかしめテール部とよりなり、かしめ部のかしめテール部はハウジングのつば部とアームの円筒部との間で挟持されるので、ボールジョイントの軸線方向に強い荷重がかかっても閉止板が移動することはなく所定の位置に維持されるため、ベアリングが軸線方向に移動することはなく、ガタが発生することがない。また、ベアリングにかかる所定の予圧が変動しないので、トルクが変動することなく品質を維持できる。さらに、潤滑剤が漏出しないので、ボールスタッドの球頭部とベアリングとの間の潤滑性も維持できる。

[Industrial applications]
The present invention relates to a joint structure of a ball joint and an arm used for, for example, a suspension system and a steering system of an automobile.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a connecting portion of a suspension device or a steering device of an automobile has been often connected by connecting a ball joint and an arm. FIG. 5 shows such a joint structure between a ball joint and an arm. The ball joint 101 has a ball stud 102 having a spherical ball head 105 and a handle portion 103 extending from the ball head 105, and a ball head 105 of the ball stud 102 swingably rotatably held. A bearing 106 made of a synthetic resin having an opening 107 at one end and coated with a lubricant on the inside, and a small opening 109 for enclosing the bearing 106 and projecting the handle 103 of the ball stud 102 from the inner periphery of the bearing 106. And a housing 108 having a large opening 110 on the other side, and a disc-shaped closing plate 112 which is fixed by caulking to the end of the large opening 110 of the housing 108. The arm 131 includes a cylindrical portion 132 and an extending portion 133 extending from the cylindrical portion 132 in a direction perpendicular to the axis. The housing 108 of the ball joint 101 is press-fitted into the inner periphery of the cylindrical portion 132 of the arm 131, and furthermore, a ball stud is provided. Other parts (not shown) were fitted to the handle 103 of the 102, and the ball joint 101 connected the arm 131 and the other parts.
[0003]
With respect to the ball joint 101, a fixed state of the closing plate 112 to the housing 108 will be described in detail. The inner periphery of the housing 108 has a small diameter portion 108a having substantially the same shape as the outer peripheral surface of the bearing 106, a large diameter portion 108c having a diameter larger than the small diameter portion 108a and forming a large opening 110, a small diameter portion 108a and a large diameter portion 108c. And a horizontal portion 108b extending in the direction perpendicular to the axis. After the closing plate 112 is arranged on the inner periphery of the large opening 110 of the housing 108, the large diameter portion 108c of the housing 108 is caulked inward, and the large opening of the housing 108 is It is swaged and fixed to the inner circumference of 110. At this time, since the length of the bearing 106 in the axial direction is slightly longer than the small diameter portion 108a of the housing 108, the closing plate 112 is caulked and fixed to the inner periphery of the large opening 110 of the housing 108, so that the bearing 106 is Pressed toward the opening 109, the length in the axial direction was slightly shortened, and a predetermined preload was applied.
[0004]
[Problems to be solved by the invention]
In the ball joint 101 as described above, a large axial load may be suddenly applied to the ball joint 101. In such a case, in particular, when the closing plate 112 is pushed toward the anti-ball head side by the load, the caulking portion of the housing 108 is loosened and the closing plate 112 moves to the anti-ball head side, and the horizontal portion of the housing 108 is moved. There may be a gap between 108b and the closing plate 112. Then, since the bearing 106 can move in the axial direction due to the clearance, play may occur. Further, since the predetermined preload is not applied to the bearing 106, the torque of the ball stud 102 may fluctuate. Further, it is conceivable that the lubricant leaks from the loosely caulked portion of the housing 108, and the lubricity between the ball head 105 of the ball stud 102 and the bearing 106 cannot be maintained.
[0005]
Accordingly, an object of the present invention is to solve the above-described problems and to provide a joint structure of a ball joint and an arm having high axial load resistance.
[0006]
[Means for Solving the Problems]
The configuration of the present invention is as follows.
