【発明の属する技術分野】
本発明は、車両のアクスルにおける転向角調整用ストッパボルトの取付構造に関し、特に、転向角調整用ストッパボルトの着脱用工具の使用性等を向上する技術に関する。
【0002】
【従来の技術】
従来、車両のアクスル、例えば、フロントアクスルは、図6に示すように、アクスル本体1の両端部に、互いにタイロッドアーム2を介して連結される左右のナックル3(右のみ図示)が夫々キングピン4を軸として回動可能に連結され、一方のナックル3に固定されるステアリングアーム5の動きによって該ナックル3による車輪の転向動作が行われる構成となっている。
【0003】
このようなフロントアクスルにおいて、図7に示すように、車輪の転向角を調整する機構として、ナックル3の所定の位置にねじ嵌合され、その頭部がアクスル本体1の両端部のキングピン4が貫通支持されるボス部1A外周面の所定の位置の近傍位置に臨まされる転向角調整用ストッパボルト6と、前記ボス部1A外周面の所定の位置に形成されて、ナックル3の転向動作時に、所定の転向角で前記ストッパボルト6頭部が係止可能な突起部7と、を設けるようにし、転向角調整用ストッパボルト6のねじ嵌合位置の調整による、その頭部の突起部7に対する位置調整によって、転向角を調整するようにしたものがある。
【0004】
尚、ナックル3には、その基部と先端部とが軸受8,9を介してホイール10が取り付けられるハブ11が回転自由に支持され、基部側の軸受8端面と、ナックル3の転向角調整用ストッパボルト6がねじ嵌合されるねじ孔12が形成されたフランジ部3Aとの間にリテーナ13(図8及び図9参照)が介装されている。
【0005】
【発明が解決しようとする課題】
しかしながら、かかる従来の構成にあっては、転向角調整用ストッパボルト6の頭部がボス部1A外周面の所定の位置の近傍位置に臨まされ、しかも、転向角調整用ストッパボルト6は、ナックル3中心軸に対して平行な軸に沿って配置されているため、その頭部の外周面がボス部1A外周面に極めて近接している。
【0006】
このような構成では、転向角調整用ストッパボルト6のねじ嵌合位置の調整時において、図10に示すように、該転向角調整用ストッパボルト6を調整したねじ嵌合位置で固定するナット14を緩めたり締めたする眼鏡レンチ等の工具15の先端部を、転向角調整用ストッパボルト6の頭部とボス部1A外周面との間の狭い隙間を通す必要があり、この際には、眼鏡レンチ等の工具15の先端部がボス部1A外周面と干渉するのが避けられず、眼鏡レンチ等の工具15の使用に苦慮し、実際には、転向角調整用ストッパボルト6のねじ嵌合位置の調整ができず、転向角調整が不可能であると言った問題点がある。
【0007】
このような問題を解決するべく、図10に示すように、ボス部1Aの外周面を削って(削り部16)、転向角調整用ストッパボルト6の頭部とボス部1A外周面との間の隙間を大きくするようなことが考えられるが、これでは、ボス部1Aの肉厚が薄くなり、ボス部1Aの強度低下を来し、採用できない。
【0008】
本発明は、以上のような従来の実情に鑑みてなされたもので、転向角調整用ストッパボルトの取付構造の改良により、転向角調整用ストッパボルトのねじ嵌合位置の調整が容易に行え、転向角の調整が容易にでき、しかも、ボス部の強度低下等の問題もない等の利点を有する車両のアクスルにおける転向角調整用ストッパボルトの取付構造を提供することを目的とする。
【0009】
【課題を解決するための手段】
上記の目的を達成するため、請求項1に係る発明は、アクスル本体の両端部に、互いにタイロッドアームを介して連結される左右のナックルが夫々キングピンを軸として回動可能に連結され、一方のナックルに固定されるステアリングアームの動きによって該ナックルによる車輪の転向動作が行われる構成であって、前記ナックルの所定の位置にねじ嵌合され、その頭部がアクスル本体の両端部のキングピンが貫通支持されるボス部外周面の所定の位置の近傍位置に臨まされる転向角調整用ストッパボルトと、前記ボス部外周面の所定の位置に形成されて、ナックルの転向動作時に、所定の転向角で前記ストッパボルト頭部が係止可能な突起部と、を設けてなる車両のアクスルにおいて、前記転向角調整用ストッパボルトを、夫々その頭部の外周面が前記ボス部外周面から所定距離離間するように、ナックル中心軸に対して傾斜する軸に沿って配置すると共に、前記ナックルには、その基部と先端部とが軸受を介してホイールが取り付けられるハブが回転自由に支持され、基部側の軸受端面と、ナックルの転向角調整用ストッパボルトがねじ嵌合されるねじ孔が形成されたフランジ部との間にリテーナが介装され、引き抜きボルトを、前記ねじ孔にねじ嵌合して、その先端部を前記リテーナに押し付けつつ、ねじ込むことにより、リテーナと軸受をナックルから引き抜くようにした車両のアクスルにおいては、前記リテーナの引き抜きボルト先端部面が当接する面を、該引き抜きボルトのナックル中心軸に対して傾斜した中心軸と略直角な面であって該引き抜きボルト先端部面と略平行な面に形成したことを特徴とする。
【0010】
請求項2に係る発明は、
前記突起部のストッパボルト頭部が係止される面を、該係止状態のときのストッパボルトの中心軸と略直交する面に形成したことを特徴とする。
【0012】
次に、かかる本発明の作用について説明する。
請求項1に係る発明において、転向角調整用ストッパボルトの頭部がアクスル本体の両端部のキングピンが貫通支持されるボス部外周面の所定の位置の近傍位置に臨まされているものの、転向角調整用ストッパボルトは、ナックル中心軸に対して傾斜する軸に沿って配置され、その頭部の外周面がボス部外周面から所定距離離間している。
【0013】
このような構成では、転向角調整用ストッパボルトのねじ嵌合位置の調整時において、該転向角調整用ストッパボルトを調整したねじ嵌合位置で固定するナットを緩めたり締めたする眼鏡レンチ等の工具の先端部を、転向角調整用ストッパボルトの頭部とボス部外周面との間の隙間を通す場合、眼鏡レンチ等の工具の先端部がボス部外周面と干渉するのが避けられ、眼鏡レンチ等の工具の使用に苦慮することがなく、転向角調整用ストッパボルトのねじ嵌合位置の調整が容易に行えるようになり、転向角の調整が可能となる。また、リテーナの引き抜きボルト先端部面が当接する面を、該引き抜きボルトの中心軸と略直角な面であって該引き抜きボルト先端部面と略平行な面に形成することにより、引き抜きボルトを、ナックル中心軸に対して傾斜する軸に沿って配置したことによって、該引き抜きボルトの先端部面が傾斜していても、リテーナ面に適正に当接する。
【0014】
請求項2に係る発明において、突起部のストッパボルト頭部が係止される面を、該係止状態のときのストッパボルトの中心軸と略直交する面に形成すれば、ストッパボルト頭部が突起部に係止されたとき、ストッパボル頭部が突起部に略直角に当たり、両者の係止状態が適正になされ、転向角の規制が適正になされる。
【0016】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。
先ず、本発明の一実施形態を図1及び図2に基づいて説明する。
【0017】
尚、これらの図において、図7及び図10と同一要素のものには同一符号を付して説明を簡単にする。
車輪の転向角を調整する機構として、ナックル3の所定の位置にねじ嵌合され、その頭部がアクスル本体の両端部のキングピンが貫通支持されるボス部1A外周面の所定の位置の近傍位置に臨まされる転向角調整用ストッパボルト6と、前記ボス部1A外周面の所定の位置に形成されて、ナックル3の転向動作時に、所定の転向角で前記ストッパボルト6頭部が係止可能な突起部7と、を設けるようにした構成は従来と同様である。
【0018】
ここの本発明においては、転向角調整用ストッパボルト6を、夫々その頭部の外周面がボス部1A外周面から所定距離離間するように、ナックル3中心軸に対して傾斜する軸に沿って配置するようにしている。
【0019】
この場合、前記突起部7のストッパボルト6頭部が係止される面7Aを、該係止状態のときのストッパボルト6の中心軸と略直交する面に形成するのが好ましい(図2参照)。
【0020】
かかる構成によれば、転向角調整用ストッパボルト6の頭部がアクスル本体の両端部のキングピンが貫通支持されるボス部1A外周面の所定の位置の近傍位置に臨まされているものの、転向角調整用ストッパボルト6は、ナックル3中心軸に対して傾斜する軸に沿って配置され、その頭部の外周面がボス部1A外周面から所定距離離間している。
【0021】
このような構成では、転向角調整用ストッパボルト6のねじ嵌合位置の調整時において、該転向角調整用ストッパボルト6を調整したねじ嵌合位置で固定するナット14を緩めたり締めたする眼鏡レンチ等の工具15(図10参照)の先端部を、転向角調整用ストッパボルト6の頭部とボス部1A外周面との間の隙間を通す場合、眼鏡レンチ等の工具15の先端部がボス部1A外周面と干渉するのが避けられ、眼鏡レンチ等の工具15の使用に苦慮することがなく、転向角調整用ストッパボルト6のねじ嵌合位置の調整が容易に行えるようになり、転向角の調整が可能となる。
【0022】
尚、転向角調整用ストッパボルト6の頭部の外周面とボス部1A外周面との間の前述した「所定距離」とは、眼鏡レンチ等の工具15の先端部がボス部1A外周面と干渉せずに、転向角調整用ストッパボルト6の頭部とボス部1A外周面との間を通過できる距離である。
【0023】
又、かかる構成によれば、ボス部1Aの外周面を削って、転向角調整用ストッパボルト6の頭部とボス部1A外周面との間の隙間を大きくする必要もなく、ボス部1Aの強度低下の問題もない。
【0024】
更に、突起部7のストッパボルト6頭部が係止される面7Aを、該係止状態のときのストッパボルト6の中心軸と略直交する面に形成すれば、ストッパボルト6頭部が突起部7に係止されたとき、ストッパボル6頭部が突起部7に略直角に当たり、両者の係止状態が適正になされ、転向角の規制が適正になされる。
【0025】
因みに、転向角調整用ストッパボルト6を、ナックル3中心軸に対して傾斜する軸に沿って配置したときに、従来のままの突起部7では、ストッパボルト6頭部が突起部7に係止されたとき、ストッパボル6頭部が突起部7に略直角に当たらず、両者の係止状態が適正になされないため、転向角の規制が適正になされなくなる。
【0026】
ここで、リテーナ18と軸受8(一方のみ図示)をナックル3から引き抜く方法として、図3に示すように、引き抜きボルト17を、ねじ孔12にねじ嵌合して、その先端部を前記リテーナ18に押し付けつつ、ねじ込むことにより、リテーナ18と軸受8をナックル3から引き抜く方法が採られている。
【0027】
この場合、転向角調整用ストッパボルト6用のねじ孔12を、ナックル3中心軸に対して傾斜する軸に沿って配置したことによって、このねじ孔12にねじ嵌合される引き抜きボルト17の先端部面はリテーナ18面に適正に当接せず、上記の引き抜き作用がスムーズに行われない。
【0028】
従って、本構成では、図4及び図5にも示すように、リテーナ18の引き抜きボルト17先端部面が当接する面18Aを、該引き抜きボルト17の中心軸と略直角な面であって該引き抜きボルト17先端部面と略平行な面に形成する。
【0029】
この場合、リテーナ18の面全体を上記の面に形成するのではなく、リテーナ18の引き抜きボルト17先端部面が当接する側の面に形成した環状の溝18Bの内面を引き抜きボルト17の中心軸と略直角な面であって該ストッパボルト17先端部面と略平行な面18Aにする。
【0030】
このような環状の溝18Bを設けて、リテーナ18の引き抜きボルト17先端部面が当接する面を、該引き抜きボルト17の中心軸と略直角な面であって該引き抜きボルト先端部面と略平行な面18Aに形成するようにした結果、ナックル3のフランジ部3Aが当たるリテーナ18の面を該フランジ部3Aの面と平行に維持でき、フランジ部3Aによるリテーナ18の押さえ固定が適正に行われ、上記の引き抜きボルト17による引き抜き作用がスムーズに行われる。
【0031】
【発明の効果】
以上説明したように、請求項1に係る発明によれば、転向角調整用ストッパボルトのねじ嵌合位置の調整時において、眼鏡レンチ等の工具の先端部がボス部外周面と干渉するのが避けられ、眼鏡レンチ等の工具の使用に苦慮することがなく、転向角調整用ストッパボルトのねじ嵌合位置の調整が容易に行えるようになり、転向角の調整が可能となると共に、ボス部の外周面を削って、転向角調整用ストッパボルトの頭部とボス部外周面との間の隙間を大きくする必要もなく、ボス部の強度低下の問題もない。また、リテーナの引き抜きボルト先端部面が当接する面を、該ストッパボルトの中心軸と略直角な面であって該引き抜きボルト先端部面と略平行な面に形成するようにしたから、引き抜きボルトの先端部面が傾斜していても、リテーナ面に適正に当接して、引き抜きボルトによる引き抜き作用がスムーズに行われる。
【0032】
請求項2に係る発明によれば、突起部のストッパボルト頭部が係止される面を、該ストッパボルトの中心軸と略直交する面に形成するようにしたから、転向角の規制が適正になされる。

[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, an embodiment of the present invention will be described with reference to FIGS.
[0017]
In these drawings, the same elements as those in FIGS. 7 and 10 are denoted by the same reference numerals to simplify the description.
As a mechanism for adjusting the turning angle of the wheel, a position near the predetermined position on the outer peripheral surface of the boss portion 1A, which is screwed into a predetermined position of the knuckle 3 and whose head is supported by the king pins at both ends of the axle body. Is formed at a predetermined position on the outer peripheral surface of the boss portion 1A so that the head of the stopper bolt 6 can be locked at a predetermined turning angle when the knuckle 3 is turned. The structure in which the projections 7 are provided is the same as that of the conventional art.
[0018]
In the present invention, the turning angle adjusting stopper bolt 6 is moved along an axis inclined with respect to the central axis of the knuckle 3 so that the outer peripheral surface of the head is separated from the outer peripheral surface of the boss portion 1A by a predetermined distance. I try to arrange it.
[0019]
In this case, the surface 7A on which the head of the stopper bolt 6 of the protrusion 7 is locked is preferably formed on a surface substantially orthogonal to the central axis of the stopper bolt 6 in the locked state (see FIG. 2). ).
[0020]
According to this configuration, although the head of the turning angle adjusting stopper bolt 6 faces the position near the predetermined position on the outer peripheral surface of the boss portion 1A through which the king pins at both ends of the axle body are supported, the turning angle The adjustment stopper bolt 6 is disposed along an axis inclined with respect to the central axis of the knuckle 3, and the outer peripheral surface of the head is separated from the outer peripheral surface of the boss part 1 </ b> A by a predetermined distance.
[0021]
In such a configuration, at the time of adjustment of the screw fitting position of the turning angle adjusting stopper bolt 6 and Ri tightened or loosened nut 14 screwed fitting position adjusting the turning angle adjusting stopper bolt 6 When passing the tip of the tool 15 such as a spectacle wrench (see FIG. 10) through the gap between the head of the turning angle adjusting stopper bolt 6 and the outer peripheral surface of the boss 1A, the tip of the tool 15 such as a spectacle wrench Can be prevented from interfering with the outer peripheral surface of the boss portion 1A, and the screw fitting position of the turning angle adjusting stopper bolt 6 can be easily adjusted without difficulty in using the tool 15 such as a spectacle wrench. The turning angle can be adjusted.
[0022]
The above-mentioned “predetermined distance” between the outer peripheral surface of the head of the turning angle adjusting stopper bolt 6 and the outer peripheral surface of the boss portion 1A is the tip of the tool 15 such as a spectacle wrench and the outer peripheral surface of the boss portion 1A. This is the distance that can pass between the head of the turning angle adjusting stopper bolt 6 and the outer peripheral surface of the boss portion 1A without interference.
[0023]
Further, according to such a configuration, it is not necessary to scrape the outer peripheral surface of the boss portion 1A to increase the gap between the head of the turning angle adjusting stopper bolt 6 and the outer peripheral surface of the boss portion 1A. There is no problem of strength reduction.
[0024]
Furthermore, if the surface 7A on which the stopper bolt 6 head of the protrusion 7 is locked is formed on a surface substantially orthogonal to the central axis of the stopper bolt 6 in the locked state, the stopper bolt 6 head protrudes. When locked to the portion 7, the stopper bolt 6 head hits the projection 7 at a substantially right angle so that the locked state of both is made appropriate and the turning angle is properly controlled.
[0025]
Incidentally, when the turning angle adjusting stopper bolt 6 is arranged along the axis inclined with respect to the central axis of the knuckle 3, the stopper bolt 6 head is locked to the protruding portion 7 in the conventional protruding portion 7. When this is done, the head of the stopper bolt 6 does not hit the projection 7 at a substantially right angle, and the locking state of the two is not properly performed, so that the turning angle is not properly regulated.
[0026]
Here, as a method of pulling out the retainer 18 and the bearing 8 (only one is shown) from the knuckle 3, as shown in FIG. 3, a pull-out bolt 17 is screw-fitted into the screw hole 12, and the tip end portion of the retainer 18 is fitted. The retainer 18 and the bearing 8 are pulled out from the knuckle 3 by being screwed in while being pressed.
[0027]
In this case, by disposing the screw hole 12 for the turning angle adjusting stopper bolt 6 along the axis inclined with respect to the central axis of the knuckle 3, the tip of the extraction bolt 17 screwed into the screw hole 12. The part surface does not properly abut on the retainer 18 surface, and the above-described extraction operation is not performed smoothly.
[0028]
