Description

【0001】
【産業上の利用分野】
本発明は、例えば二つの部品間を連結する長さ可変の連結部材の結合構造及び結合方法に関する。
【0002】
【従来の技術】
二つの部品の間を連結する二つの連結部材を結合するときに、長さを調整する必要がある場合がある。例えば、自動車のステアリング装置もその一つである。その自動車のステアリング構造の一つを図1を基に説明する。ステアリングホイール81からステアリングシャフト82が延び、ギヤーボックス83の軸に接続する。ギヤーボックス83の軸には2本のロッド1(101)が接続し軸線方向に略対称に延出しており、二本のロッド1(101)の反ギヤーボックス側端部にはボールジョイントが設けられている。ボールジョイントはロッド1(101)と車輪支持体84を連結しており、車輪支持体84は車輪85を支持している。このような構造のステアリング装置ではステアリングホイール81の操作がステアリングシャフト82を介してギヤーボックス83の軸に伝えられる。するとギヤーボックス83内のギヤー(図示せず)が回転し軸が動く。軸の動きはさらに2本のロッド1(101)を介して車輪支持体84に伝えられ、車輪支持体84の動きにより車輪85が方向を転換し運転手の所望の方向へと自動車を移動させることができる。
【0003】
このようなステアリング装置においては、多くの部品が使用されている。そのため組み立てる過程において各部品の寸法公差内の寸法誤差や組付の誤差が集積して大きな誤差が発生するため、その誤差を吸収して調整し、所望の車輪の取付状態を得る必要が生じる。このようなステアリング装置においては、ギヤーボックス83と車輪支持体84を繋ぐ二本のロッド1(101)が各々別体の二本のロッドである第一ロッド11(111)及び第二ロッド51(151)を結合して作られており、その結合状態を調整してロッド1(101)の長さを変更し、ギヤーボックス83と車輪支持体84の間に生じた集積誤差を吸収して所望の車輪の取付状態を得ていた。
【0004】
このようなロッドを形成する第一ロッド111及び第二ロッド151の結合構造を図7を基に説明する。まず車輪支持体84と連結する第一ロッド111について説明する。第一ロッド111は球状の第一球頭部115と第一球頭部115から突出する第一柄部113とからなる第一ボールスタッド112と、第一ボールスタッド112の第一球頭部115を内包する合成樹脂製の第一ベアリング116と、第一ベアリング116を包持する第一ハウジング118とを備える。第一ハウジング118は、ロッド101の軸方向に延出するアーム部121を有する。アーム部121は端部内周に雌螺子部122が形成され、端部外周には略六角形状の第一スパナ掛け部117が形成されている。また、ギヤーボックス83側に配置される第二ロッド151は、球状の第二球頭部155とその第二球頭部155から延出する第二柄部153とを有する第二ボールスタッド152を備える。この第二ボールスタッド152の第二柄部153の反球頭部側には第二雄螺子部154と、第二雄螺子部154より第二球頭部155側に外周面が六角形状となる第二スパナ掛け部157が形成される。また第二ボールスタッド152の第二球頭部155は合成樹脂製の第二ベアリング156に包持され、第二ベアリング156は略カップ形状の第二ハウジング158に保持される。この第二ハウジング158は一方に第二ボールスタッド152の第二柄部153を突出させる開口159を有し、反開口側の底部160からは反球頭部側に延びるハウジング雄螺子部162が形成される。このような構造の第一ロッド111と第二ロッド151は、第一ロッド111の雌螺子部122に第二ロッド151の第二雄螺子部154が螺合し、第二ロッド151の第二雄螺子部154に螺合したナット133が第一ロッド111の雌螺子部122側端部に接した状態で締め付けられて、第一ロッド111と第二ロッド151は相対的に回転不能な状態に結合されていた。
【0005】
上記の如き第一ロッド111と第二ロッド151の結合方法を説明する。まず第一ロッド111の第一ボールスタッド112の第一柄部113と車輪支持体84を結合する。続いて第二ロッド151の第二ハウジング158のハウジング雄螺子部162をギヤーボックス83の軸と結合する。次にナット133を第二ロッド151の第二ボールスタッド152の第二雄螺子部154に適当な位置まで螺合させる。続いて第一ロッド111の雌螺子部122に第二ロッド151の第二雄螺子部154を螺合し、スパナを第二スパナ掛け部157に掛けて第二ロッド151を回転させ、第一ロッド111及び第二ロッド151からなるロッド101の長さを調整後、ナット133をスパナで締め付け側に廻し、ナット133を第一ロッドの雌螺子部122側端部に当接させた状態で更にナット133を締め付けて固定し、第一ロッド111と第二ロッド151を相対的に回転不能な状態としていた。
【0006】
【発明が解決しようとする課題】
車輪支持体84とギヤーボックス83間が所望の長さで連結されると、その状態で第一ロッド111と第二ロッド151を固定するため、第二ロッド151の第二雄螺子部154に螺合したナット133を第一ロッド111の雌螺子部122端面に当接させ、ナット133を締め付けて第一ロッド111と第二ロッド151を相対的に回転不能な状態に結合する。このとき第一ロッド111のアーム121部外周面に形成された第一スパナ掛け部117にスパナを掛けて第一ロッド111を回転不能な状態で固定し、ナット133に別のスパナを掛けて締め付けるという方法が一般的である。しかし、レイアウトの関係で作業者が第一ロッド111にスパナを掛けることが困難な場合がある。そのような場合は第一ロッド111を固定せずにナット133を回転させて締め付けるため、第一ロッド111がナット133に伴って回転してしまい、ロッド101の長さが変わってしまうということがあった。
【0007】
よって、本発明は上記の如き課題を解決し、二部品間を連結する長さ調整可能な二本の連結部材の結合時に、調整後の所望の長さを保持できる結合構造及び結合方法を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明の結合構造は以下の通りである。
【0009】
二部品間を長さ調整可能な構造で連結する二本の部材の結合構造であって、雌螺子部を有する一方部材と、雌螺子部に螺合し、軸方向に切り欠かれた凹部が形成される雄螺子部を有する他方部材と、内側に突出する凸部が雄螺子部の凹部に嵌合し、一部が雌螺子部外周面にかしめ固定される環状のワッシャと、他方部材の雄螺子部に螺合しワッシャと接する状態で一方部材と他方部材とを固定するナットとよりなる。
【0010】
また、本発明の結合方法は以下の通りである。
【0011】
二部品間を長さ調整可能な構造で連結する二本の部材の結合方法であって、他方部材の軸方向に切り欠かれた凹部が形成される雄螺子部の一端端部からナットを螺合し、ついで内側に突出する凸部が形成されるワッシャを、凸部を雄螺子部の凹部に嵌合させた状態で雄螺子部に挿入した後、雄螺子部を一方部材の雌螺子部と螺合して長さ調整を行い、続いてワッシャの一部を雌螺子部外周にかしめて固定した後にナットをワッシャに接した状態に移動させて一方部材と他方部材とを固定する。
【0012】
【実施例】
以下、本発明の実施例を図1乃至図6を基に説明する。
【0013】
図2に示されるのは、先に説明した図1に示されるステアリング装置に使用されるロッド1を構成する本発明の実施例による第一ロッド11と第二ロッド51との結合構造である。車輪支持体84側に配置される第一ロッド11は、球状の第一球頭部15と第一球頭部15から突出し反球頭部側に第一雄螺子部14が形成される第一柄部13とからなる第一ボールスタッド12と、第一ボールスタッド12の第一球頭部15を揺動回動自在に内包し一方に開口する第一ベアリング開口部16aを有する合成樹脂製の第一ベアリング16と、第一ベアリング16を包持する略円筒状の包持部を有する第一ハウジング18とを備える。第一ハウジング18には、一方に第一ボールスタッド12の第一柄部13を突出させる小開口19、他方に端部内周に円盤状の閉止板24がかしめ固定される大開口20と、ロッドの軸方向に延出するアーム部21とを有する。アーム部21は端部内周に雌螺子部22が形成され、雌螺子部22外周面には六角形状の第一スパナ掛け17が形成されている。
【0014】
また、ギヤーボックス83側に配置される第二ロッド51は球状の第二球頭部55とその第二球頭部55から延出する第二柄部53とを有する第二ボールスタッド52を備える。図3に示す如くこの第二ボールスタッド52の第二柄部53の反球頭部側には軸方向に切りかかれた凹部61が形成される第二雄螺子部54と、第二雄螺子部54より第二球頭部55側に外周面が六角形状となる第二スパナ掛け部57が形成される。また第二ボールスタッド52の第二球頭部55は合成樹脂製の第二ベアリング56に包持され、第二ベアリング56は略カップ形状の第二ハウジング58に保持される。この第二ハウジング58は一方に第二ボールスタッド52の第二柄部53を突出させるハウジング開口59を有し反開口側の底部60からは反球頭部側に延びるハウジング雄螺子部62が形成される。
【0015】
続いて上記第一ロッド11と第二ロッド51との結合構造を説明する。第一ロッド11の雌螺子部22には第二ロッド51の第二雄螺子部54が螺合し、図4に示される如く内側に突出する凸部32が形成される環状のワッシャ31が第二雄螺子部54の凹部61に凸部32が嵌合した状態で挿入されており、そのワッシャ31は第一ロッド11の雌螺子部22側端部に接触しワッシャ31の一部34が第一ロッド11の第一スパナ掛け部17にかしめ固定されている。ナット33はワッシャ31に接触した状態で第一ロッド11と第二ロッド51を固定している。
【0016】
続いて上記第一ロッド11と第二ロッド51との結合方法を図を基に説明する。
【0017】
まず、第一ロッド11の第一ボールスタッド12の第一柄部13の第一雄螺子部14を車輪支持体84に結合する。同時に第二ロッド51は第二ハウジング58のハウジング雄螺子部62をギヤーボックス83の軸と結合し、続いて第二ボールスタッド52の第二雄螺子部54の適当な位置までナット33を螺合する。次いで図5に示す如くワッシャ31の凸部32を第二ロッド51の第二雄螺子部54に形成された凹部61に嵌合させた状態でワッシャ31を第二雄螺子部54に挿入する。続いて図6に示す如く第二ロッド51の第二雄螺子部54を第一ロッド11の雌螺子部22に螺合する。このとき第二ロッド51の第二スパナ掛け部57に作業者がスパナを掛けて、ロッド1が車輪を適正な状態に取り付けられるように、第一ロッド11の雌螺子部22と第二ロッド51の第二雄螺子部54の螺合する長さを調整する。そしてロッド1を適正な長さに設定したのち、図6に示す如く第二ロッド51の第二雄螺子部54に挿入されたワッシャ31を移動させて第一ロッド11のアーム21部の雌螺子部22端面23に当接させ、ワッシャ31の一部34を第一ロッド11の第一スパナ掛け部17にかしめ固定する。ここでワッシャ31を第一ロッド11に固定するとともに、ワッシャ31の凸部32が第二ロッド51の第二雄螺子部54に形成された凹部61に嵌合しているので、第一ロッド11と第二ロッド51を相対的に回転不能な状態とする。最後に第二ロッド51の第二雄螺子部54に螺合したナット33をワッシャ31に当接する位置まで移動させて、作業者がスパナをナット33に掛けナット33を回転させて締め付けることにより第二雄螺子部54を押圧する。これは、第二雄螺子部54と雌螺子部22の螺合する各螺子山の間には隙間が生じているためガタツキが発生するが、ナット33により第二雄螺子部54を押圧して各螺子山を一方向に当接させることにより第二雄螺子部54と第一雌螺子部22の螺合状態を強固にしてガタツキをなくし、第一ロッド11と第二ロッド51とを軸方向に対して相対的に移動不能な状態に固定する。これにより第一ロッド11と第二ロッド51の結合が完了する。
【0018】
以上のように本発明の結合方法によれば、第二ロッド51の軸方向に切り欠かれた凹部61が形成される第二雄螺子部54の一端端部からナット33を螺合し、ついで内側に突出する凸部32が形成されるワッシャ31を、凸部32を第二ロッド51の第二雄螺子部54の凹部61に嵌合させた状態でワッシャ31を第二雄螺子部54に挿入した後、第二雄螺子部54を第一ロッド11の雌螺子部22と螺合して長さ調整を行い、続いてワッシャ31の一部34を第一ロッド11の雌螺子部22外周にかしめて固定した後、ナット33をワッシャ31に接した状態に移動させてナット33を回転させて締め付け第一ロッド11と第二ロッド51とを固定するので、第一ロッド11と第二ロッド51が相対的に回転不能な状態で、第一ロッド11と第二ロッド51が軸方向に対して相対的に移動不能な状態にナット33で締め付けることができる。
【0019】
また、本発明の結合構造によれば、雌螺子部22を有する第一ロッド11と、雌螺子部22に螺合し、軸方向に切り欠かれた凹部61が形成される第二雄螺子部54を有する第二ロッド51と、内側に突出する凸部32が第二ロッド51の第二雄螺子部54の凹部61に嵌合し、ワッシャ31の一部34が第一ロッド11の雌螺子部22外周面にかしめ固定される環状のワッシャ31と、第二雄螺子部54に螺合したナット33がワッシャ31と接する状態で第一ロッド11と第二ロッド51とを固定しているので、第一ロッド11と第二ロッド51とが相対的に回転不能な状態で固定された後、第一ロッド11と第二ロッド51とが軸方向に移動不能な状態でナット33により固定されている。
【0020】
尚、上記実施例においては、本発明の結合構造が自動車のステアリング装置に使用されるロッド1に使用されているが、本発明がこの製品に限定されるわけではなく、二つの部品間を連結する複数の連結部材が長さ調整可能である場合に適用される。また、ワッシャ31は一部をかしめ固定されているが、かしめ箇所は一箇所に限定されるわけではない。
【0021】
【発明の効果】
以上のように本発明の結合方法によれば、二部品間を長さ調整可能な構造で連結する二本の部材の結合方法であって、他方部材の軸方向に切り欠かれた凹部が形成される雄螺子部の一端端部からナットを螺合し、ついで内側に突出する凸部が形成されるワッシャを、凸部を雄螺子部の凹部に嵌合させた状態で、雄螺子部を一方部材の雌螺子部と螺合して長さ調整を行い、続いてワッシャの端部の一部を雌螺子部外周にかしめて固定した後にナットをワッシャに接した状態に移動させて一方部材と他方部材とを固定するので、一方部材と他方部材が相対的に回転不能な状態で、一方部材と他方部材が軸方向に対して相対的に移動不能な状態にナットで締め付けることができるので、最後にナットを締め付けて固定するときに一方部材を固定しなくても他方部材が相対的に回転しないので、長さ調整後に長さが変わってしまうことがない。
【0022】
また、本発明の結合構造によれば、二部品間を長さ調整可能な構造で連結する二本の部材の結合構造であって、雌螺子部を有する一方部材と、雌螺子部に螺合し、軸方向に切り欠かれた凹部が形成される雄螺子部を有する他方部材と、内側に突出する凸部が雄螺子部の凹部に嵌合し、一部が前記雌螺子部外周面にかしめ固定される環状のワッシャと、雄螺子部に螺合しワッシャと接する状態で一方部材と他方部材とを固定するナットとよりなるので、一方部材と他方部材とが相対的に回転不能な状態で固定された後、一方部材と他方部材とが軸方向に移動不能な状態でナットにより固定されているため、長さ調整をした後に長さが変わってしまうということがない。
