Description

【０００１】
【発明の属する技術分野】
本発明は、棒材の外周にずれ止め部材をフランジ状に組み付けて固定部材と干渉させるようにすることで該棒材の軸線方向への移動を規制するための棒材のずれ防止構造に関し、特に車両用懸架装置のスタビライザに用いるのに適した棒材のずれ防止構造に関するものである。
【０００２】
【従来の技術】
例えば、車両に用いられる所謂アンチロールバーのようなスタビライザにあっては、両端が湾曲してＵ字状をなす棒材（スタビライザ）の中央部分の両湾曲部寄りを車体に支持し、湾曲部の先端を懸架アームに保持するものがある。上記車体への支持は、スタビライザに巻装したゴムブシュをＵ字状をなすステイで包み込み、このステイをボルト等で車体に固定するのが一般的である。
【０００３】
【発明が解決しようとする課題】
しかしながら、車両走行中に於て車両の横方向、即ちスタビライザの中央部分に於ける軸線方向の力が該スタビライザに入力されると、その大きさによってはゴムブシュ及びステイでは抑えることができず、ゴムブシュの変形量が大きくなって他部品と干渉して異音を発生したり、スタビライザの両湾曲部の先端のリンクに損傷を与えることが懸念されるのみでなく、スタビライザ自体の耐久性や信頼性あるいは乗り心地にも影響する。
【０００４】
そこで、例えばスタビライザの上記ゴムブシュに隣接する位置に、金属ワッシャを環装してかしめ、ゴムブシュの軸線方向への変形を抑制するスタビライザの横ずれ防止構造が提案されているが、スタビライザ端部からワッシャを挿入する必要があり、組み付け作業性が悪いと共にかしめ部の表面には塗装が付かないことから耐食性に問題がある。
【０００５】
また、金属ワッシャに代えて両端にフランジを有する別のゴムブシュを装着し、この別のゴムブシュにクリップバンドを嵌装して締め付け、固定し、ゴムブシュの軸線方向への変形を抑制するものも提案されているが、上記別のゴムブシュやクリップバンドを手作業で組み付けなければならず、組み付け作業性が悪いばかりでなく、横方向の荷重を受けたとき、横ずれに耐え得る少なくとも２キロニュートン（ＫＮ）の強度が必ずしも得られず、上記別のゴムブシュも変形し、ずれが発生してストッパとして機能が得難いという問題があった。
【０００６】
更に、実開平４−１３３９０７号公報には、その端部同士を互いに結合させた状態でスタビライザの外周に圧接する環状をなすような２つの半環状部を有し、スタビライザの外周に環溝を形成し、この溝に入り込むように半環状部を合わせ、これをゴムブシュにて覆ったものが開示されている。
【０００７】
この構造によれば、ゴムブシュの横ずれは防止できるもののスタビライザの外周に環溝を形成することで、該環溝部分に応力が集中し、スタビライザの捻り強度が低下するばかりでなく、トーションバーとしての作用が損なわれることが考えられる。云うまでもなくスタビライザを太くしても必ずしも所望のばね作用が得られるものではなく、逆に重量化・大型化することが懸念される。
【０００８】
尚、上記した問題はスタビライザに限らず、軸線方向へのずれを防止することが望まれる棒材の支持構造に云えるものである。
【０００９】
本発明は上記した従来技術の問題点に鑑みなされたものであり、その目的は、簡単な構造にて棒材の横ずれを確実に防止でき、自動組立も容易であり、しかも十分な耐久性、強度を有する棒材のずれ防止構造を提供することにある。
【００１０】
【課題を解決するための手段】
上記した目的は、本発明によれば、棒材の外周に、その端部同士を互いに結合させた状態で圧接するずれ止め部材をフランジ状に組み付けて固定部材と干渉させるようにすることで該棒材の軸線方向への移動を規制するための棒材のずれ防止構造であって、前記ずれ止め部材２０が、前記棒材（スタビライザ１）を囲繞せずに前記端部同士を互いに結合させると、その内周輪郭の形状が楕円、台形及び多角形のうちから選択される形状をなし、かつその円周方向中間部に径方向外向きに突出するＵ字状の遊び部２０ａが形成されており、前記棒材を囲繞して前記端部同士を互いに結合させると、曲げ変形してその内周面が前記棒材の外周に圧接するようになっており、かつ前記棒材の外周面と前記ずれ止め部材の内周面との間に滑り止め用微粒子（研削用ト粒１２）を介在させることを特徴とする棒材のずれ防止構造を提供することにより達成される。
【００１１】
【発明の実施の形態】
以下に、本発明の好適な一実施形態を添付の図を参照して詳細に説明する。
【００１２】
図１は本発明の適用対象の一例である自動車のスタビライザの構造を示す斜視図である。両端が湾曲してＵ字状をなすスタビライザ１の中央部分の両湾曲部寄りには、ゴムブシュ２、３が設けられ、このゴムブシュ２、３がＵ字状をなすステイ４、５により図示されない車体下部に支持されている。また、湾曲部の先端は懸架アーム７、８にゴムブシュ等を介して保持されている。また、スタビライザ１のゴムブシュ２、３に隣接する位置には、アルミニウム材からなり、フランジ状をなすずれ止め部材１０、１１が環着している。
【００１３】
図１の要部を拡大して見た図２に示すように、ずれ止め部材１０は、２つの半環状部材１０ａ、１０ｂを結合してなる。半環状部材１０ａ、１０ｂの対応する両端部には互いに嵌合する係合部１３ａと対応係合部１３ｂとが形成されている。これら係合部１３ａは頭部と首部とを有し、対応係合部１３ｂの凹部にこの頭部を嵌め込むことにより互いに係合して環状のずれ止め部材１０をなし、この状態を維持するようになる。
【００１４】
２つの半環状部材１０ａ、１０ｂは単に結合した状態ではスタビライザ１よりも小径であるが、図３（ａ）の状態から半環状部材１０ａ、１０ｂをスタビライザ１を挟むように整合させ、図３（ｂ）の状態とし、更に外周から加圧する（かしめる）ことにより塑性変形させ、かつスタビライザ１の外周面に各半環状部材１０ａ、１０ｂの内周面を圧接させ、係合部１３ａと対応係合部１３ｂとを嵌合させ、図２の状態に結合させる。
【００１５】
ここで、各半環状部材１０ａ、１０ｂの内周面、即ちずれ止め部材１０の内周面には予め滑り止め用微粒子としての研削用ト粒１２がその全面に塗布されている。この研削用ト粒１２が、スタビライザ１の外周面にずれ止め部材１０の内周面が圧接する際に両面に食い込み、両者が強固に固定される。この研削用ト粒１２としては、ＪＩＳＲ６１１の人造研削材にその規格が定められたアルミナ質研削材や炭化けい素質研削材等が適している。これらアルミナ質研削材等、単体では塗布した状態を維持し難い滑り止め用微粒子を用いる場合、一液の速乾性など作業性に優れた接着剤を混ぜて塗布し、表面に接着することにより作業途中での脱落等が防止でき、その作業性が向上する。
【００１６】
尚、ずれ止め部材１１の構造はについてはずれ止め部材１０と同様であるのでその詳細な説明を省略する。
【００１７】
これらずれ止め部材１０、１１により、スタビライザ１に横方向、即ちスタビライザ１の中央部の軸線方向への力が加わったとき、ゴムブシュ２やステイ３がこのずれ止め部材１０、１１に当接して横ずれが防止される。
【００１８】
図４は、本発明による棒材のずれ防止構造の一例を示すずれ止め部材２０の側面図である。この構造では、組み付け前のずれ止め部材２０は１部品からなり、略Ｃ字状をなしている。その中間部には、Ｕ字状の遊び部２０ａが形成されている。また、互いに対応する端部には上記同様な係合部と対応係合部とが形成されている。従って、ずれ止め部材２０を１種類の板金加工により容易に得られるのみでなく、部品の管理も容易になる。
【００１９】
このずれ止め部材２０をスタビライザ１に環装し、上記同様に外周から加圧する（かしめる）ことにより、Ｕ字状の遊び部２０ａが伸び、係合部と対応係合部とが嵌合し、スタビライザ１にずれ止め部材２０が固定される。それ以外の構造は、上記構成と同様であり、ずれ止め部材２０の内周面とスタビライザ１の外周面との間に研削用ト粒が介在し、両面に食い込み、両者が強固に固定される点も同様である。
【００２０】
尚、上記各実施形態では、棒材として自動車のスタビライザを挙げたがこれに限定されるものではなく、軸線方向へのずれを防止することが望まれる棒材の支持構造全てに適用可能であることは云うまでもない。例えば、棒材としては中実、中空の何れでも良く、その材料も鉄、非鉄金属、プラスチック等どのようなものでも良い。
【００２１】
上記図２、３に示した形態では、組み付け前のずれ止め部材の端面形状が円形をなすものについて述べたが、本発明においては、棒材を囲繞せずに端部同士を互いに結合させると、その端面形状（内周輪郭）が楕円、台形及び多角形のうちから選択される形状をなすものとした。その際、上記図２、３に示したものでは加圧する（かしめる）ことにより塑性変形させ、即ち材料の伸びにより、スタビライザの外周面にずれ止め部材の内周面を圧接させ、係合部と対応係合部とを嵌合させたが、材料の伸びに期待した変形は高い加圧力を必要とする。そこで本発明は、組み付け前のずれ止め部材の形状を楕円、台形、多角形などとし、その全長とスタビライザの外周長とを略一致させ、曲げ変形と滑り止め用微粒子がスタビライザの外周面及びずれ止め部材の内周面に食い込む変形とでスタビライザの外周面にずれ止め部材の内周面を圧接させ、係合部と対応係合部とを嵌合させれば、加圧力を低くすることが可能となる。
【００２２】
更に、上記各実施形態では、ずれ止め部材の材料としてアルミニウム材を例に挙げたが、軟鋼、硬質プラスチック、強化プラスチック等を用いても良い。例えば、軟鋼製のずれ止め部材を鉄製の棒材に取り付ける場合、ずれ止め部材に、鉄よりイオン化傾向の大きい亜鉛塗装をすることにより棒材の錆の発生を抑制することができる。そして、この亜鉛塗料に滑り止め用微粒子を混入しても良い。また、ブラスチック類をずれ止め部材として用いる場合、棒材にずれ止め部材を熱融着させるが、熱融着の前または後にずれ止め部材を外周から加圧して滑り止め用微粒子を棒材に食い込ませると良い。
【００２３】
【実施例】
スタビライザφ３０の横ずれ防止構造として、アルミニウム材からなる一対の半環状部材を結合するずれ止め部材を用い、その板厚を４ｍｍ、幅を１７ｍｍとしたものを用いた。また、研削用ト粒としてはアルミナ質研削材を用いた。この板厚、板幅、研削用ト粒の粒度、組み付け前の各半環状部材の寸法は横ずれ圧力、仕様を考慮して変えることができる。例えば、研削用ト粒としてのアルミナ質研削材の粒度は、ＪＩＳＲ６１１に定められる粗粒４６番から１２０番の範囲で、要求されるずれ荷重強度に対し満足できる結果を示した。粒度がこれ以上荒くなれば装着する棒材表面の塗装膜に過大な傷を与える恐れがあり、逆に細かくなれば強度が低下することから、この粒度範囲がスタビライザの横ずれ防止構造としては適切な使用条件となる。
【００２４】
ここで、要求されるずれ止め強度が、スタビライザ側の仕様によって変わる場合は、塗布する上記アルミナ質研削材等の滑り止め用微粒子の量を加減することにより適切なずれ止め強度を得ることができる。このときの管理は、ずれ止め部材内周面の全表面積と滑り止め用微粒子の塗布面積との比によって行うことができる。
【００２５】
図５に、この構造による横ずれ荷重−変位の関係を測定したものを示す。このグラフにより、この構造が充分な横ずれ強度を有し、基準の２ＫＮを大きく上回っていることがわかる。尚、アルミナ質研削材に代えて炭化けい素質研削材を滑り止め用微粒子として用いても同様な結果が得られる。
【００２６】
【発明の効果】
以上の説明により明らかなように、本発明の棒材のずれ防止構造によれば、棒材を囲繞するように端部同士を互いに結合させて棒材の外周に圧接させることにより環状のずれ止め部材とし、かつ棒材の外周面とずれ止め部材の内周面との間に滑り止め用微粒子を介在させるという簡単な構造をもって、ずれ止め部材が強固に棒材に固定され、棒材の軸線方向へのずれを確実に防止でき、また充分な耐久性及び強度を得ることができ、しかも自動組立が容易になる。

BACKGROUND OF THE INVENTION
The present invention relates to a rod slip prevention structure for restricting movement of the rod in the axial direction by assembling a stopper member on the outer periphery of the rod in a flange shape so as to interfere with the fixing member, More particularly, the present invention relates to a structure for preventing the shift of a bar material suitable for use in a stabilizer of a suspension device for a vehicle.
[0002]
[Prior art]
For example, in a stabilizer such as a so-called anti-roll bar used in a vehicle, both sides of the center portion of a bar material (stabilizer) that is curved at both ends are supported by the vehicle body, There is one that holds the tip of the arm on the suspension arm. The support to the vehicle body is generally performed by wrapping a rubber bush wound around a stabilizer with a U-shaped stay and fixing the stay to the vehicle body with a bolt or the like.
[0003]
[Problems to be solved by the invention]
However, when a lateral force of the vehicle, that is, an axial force at the center portion of the stabilizer is input to the stabilizer while the vehicle is running, depending on the magnitude of the force, the rubber bush and the stay cannot be suppressed. Not only is there a concern that the amount of deformation will increase and interfere with other parts to generate abnormal noise, or damage to the links at the ends of both curved parts of the stabilizer, but also the durability and reliability of the stabilizer itself. It also affects the ride comfort.
[0004]
Therefore, for example, a stabilizer lateral slip prevention structure that suppresses deformation in the axial direction of the rubber bushing by attaching a metal washer to the position adjacent to the rubber bushing of the stabilizer has been proposed, but the washer is attached from the end of the stabilizer. There is a problem in corrosion resistance because it is necessary to insert, the assembly workability is poor and the surface of the caulking portion is not coated.
[0005]
In addition, another rubber bush having flanges at both ends instead of a metal washer is mounted, and a clip band is fitted to this rubber bush to be tightened and fixed to suppress deformation of the rubber bush in the axial direction. However, the above-mentioned other rubber bushes and clip bands must be assembled by hand, and the assembly workability is not only poor, but also at least 2 kilonewtons (KN) that can withstand lateral displacement when subjected to lateral loads. However, there is a problem in that the above-mentioned another rubber bush is also deformed and a deviation occurs, making it difficult to obtain a function as a stopper.
[0006]
Furthermore, Japanese Utility Model Laid-Open No. 4-133907 has two semi-annular portions that form an annular shape that presses against the outer periphery of the stabilizer in a state where the ends thereof are coupled to each other, and an annular groove is formed on the outer periphery of the stabilizer. It is disclosed that a semi-annular portion is formed so as to enter the groove and covered with a rubber bush.
[0007]
According to this structure, although the lateral displacement of the rubber bush can be prevented, by forming an annular groove on the outer periphery of the stabilizer, stress is concentrated on the annular groove portion, not only reducing the torsional strength of the stabilizer, but also as a torsion bar. It is conceivable that the action is impaired. Needless to say, even if the stabilizer is thickened, a desired spring action is not always obtained, and there is a concern that the weight and size of the stabilizer may be increased.
[0008]
The above-described problem is not limited to the stabilizer, but can be said to be a support structure for a bar material that is desired to prevent displacement in the axial direction.
[0009]
The present invention has been made in view of the above-described problems of the prior art, and its purpose is to reliably prevent the lateral displacement of the bar with a simple structure, easy to assemble automatically, and sufficient durability, An object of the present invention is to provide a structure for preventing the deviation of a bar having strength.
[0010]
[Means for Solving the Problems]
According to the present invention, the above-described object is achieved by assembling, in a flange shape, an anti-slip member that is press-contacted to the outer periphery of the bar member in a state where the ends are coupled to each other, thereby causing interference with the fixing member. A structure for preventing a shift of a bar for restricting the movement of the bar in the axial direction, wherein the shift preventing member 20 connects the ends to each other without surrounding the bar (stabilizer 1) . And the shape of the inner peripheral contour is a shape selected from an ellipse, a trapezoid, and a polygon, and a U-shaped play portion 20a projecting radially outward is formed at the circumferential intermediate portion. And when the ends are joined to each other by surrounding the bar , the inner peripheral surface thereof is pressed against the outer periphery of the bar by bending deformation, and the outer peripheral surface of the bar Between the inner surface of the stopper member and the slip prevention member Is achieved by providing a displacement prevention structure of bars, characterized in that an intervening child (grinding preparative particle 12).
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0012]
Figure 1 is a perspective view showing a structure of a is vehicle stabilizer an example of application of the present invention. Rubber bushes 2 and 3 are provided near both curved portions of the central portion of the stabilizer 1 which is curved at both ends to form a U-shape. The rubber bushes 2 and 3 are not shown by the U-shaped stays 4 and 5. Supported at the bottom. Further, the distal end of the curved portion is held by the suspension arms 7 and 8 via rubber bushes or the like. Further, at positions adjacent to the rubber bushes 2 and 3 of the stabilizer 1, there are ring-fitted anti-slip members 10 and 11 made of an aluminum material and forming a flange shape.
[0013]
As shown in FIG. 2 in which the main part of FIG. 1 is enlarged, the slip prevention member 10 is formed by joining two semi-annular members 10a and 10b. Engaging portions 13a and corresponding engaging portions 13b that are fitted to each other are formed at both corresponding ends of the semi-annular members 10a and 10b. These engaging portions 13a have a head portion and a neck portion, and are engaged with each other by fitting the head portion into a recess of the corresponding engaging portion 13b to form an annular detent member 10 and maintain this state. It becomes like this.
[0014]
The two semi-annular members 10a and 10b are smaller in diameter than the stabilizer 1 in the combined state, but the semi-annular members 10a and 10b are aligned so as to sandwich the stabilizer 1 from the state of FIG. b), and further plastically deforming by pressurizing (caulking) from the outer periphery, and the inner peripheral surfaces of the semi-annular members 10a and 10b are brought into pressure contact with the outer peripheral surface of the stabilizer 1 to correspond to the engaging portion 13a. The joining portion 13b is fitted and joined to the state shown in FIG.
[0015]
Here, grinding grains 12 as anti-slip particles are applied to the entire inner circumferential surfaces of the semi-annular members 10a and 10b, that is, the inner circumferential surface of the displacement preventing member 10, in advance. The grinding grains 12 bite into both surfaces when the inner peripheral surface of the stopper member 10 comes into pressure contact with the outer peripheral surface of the stabilizer 1, and both are firmly fixed. As the grinding grains 12, alumina-based abrasives, silicon carbide abrasives, etc., whose standards are defined as JIS R611 artificial abrasives are suitable. When using non-slip particles such as these alumina-based abrasives that are difficult to maintain when applied alone, work by adhering to the surface by mixing and applying an adhesive that excels in workability, such as quick drying of a single solution. Dropping in the middle can be prevented, and the workability is improved.
[0016]
Since the structure of the stopper member 11 is the same as that of the stopper member 10, the detailed description thereof is omitted.
[0017]
When the force in the lateral direction, that is, the axial direction of the central portion of the stabilizer 1 is applied to the stabilizer 1 by these displacement preventing members 10, 11, the rubber bush 2 and the stay 3 abut against the displacement preventing members 10, 11 and are laterally displaced. Is prevented.
[0018]
FIG. 4 is a side view of the displacement preventing member 20 showing an example of the rod displacement preventing structure according to the present invention. In this structure, the anti-slip member 20 before assembly consists of one part and has a substantially C-shape. A U-shaped play portion 20a is formed at the intermediate portion. In addition, the end portions corresponding to each other are formed with the same engaging portion and the corresponding engaging portion as described above. Therefore, not only the slip prevention member 20 can be easily obtained by one type of sheet metal processing, but also the management of the parts is facilitated.
[0019]
By mounting the slip prevention member 20 on the stabilizer 1 and pressurizing (caulking) from the outer periphery in the same manner as described above, the U-shaped play portion 20a extends, and the engaging portion and the corresponding engaging portion are fitted. The slip prevention member 20 is fixed to the stabilizer 1. The rest of the structure is the same as that described above, and grinding grains are interposed between the inner peripheral surface of the anti-slip member 20 and the outer peripheral surface of the stabilizer 1, bite into both surfaces, and both are firmly fixed. The same applies to the point.
[0020]
In each of the above embodiments, an automobile stabilizer is used as the bar. However, the present invention is not limited to this, and the present invention can be applied to all bar support structures that are desired to prevent displacement in the axial direction. Needless to say. For example, the bar may be solid or hollow, and the material may be any material such as iron, non-ferrous metal, plastic, or the like.
[0021]
In the embodiment shown in FIGS. 2 and 3 described above, the shape of the end face of the slip prevention member before assembly is circular. However, in the present invention, when the end portions are joined to each other without surrounding the bar material, The end face shape (inner peripheral contour) is a shape selected from an ellipse, a trapezoid and a polygon. At that time, in the case shown in FIGS. 2 and 3, the inner peripheral surface of the anti-slipping member is pressed against the outer peripheral surface of the stabilizer by the plastic deformation by pressurizing (caulking), that is, by the elongation of the material. However, the deformation expected for the elongation of the material requires high pressure. In view of this, the present invention is designed so that the shape of the anti-slip member before assembly is an ellipse, trapezoid, polygon, etc., and the overall length of the anti-slip member and the outer peripheral length of the stabilizer are substantially the same. If the inner peripheral surface of the anti-slip member is brought into pressure contact with the outer peripheral surface of the stabilizer by deformation that bites into the inner peripheral surface of the stopper member, and the engaging portion and the corresponding engaging portion are fitted, the applied pressure can be lowered. It becomes possible.
[0022]
Further, in each of the above-described embodiments, the aluminum material is taken as an example of the material of the slip prevention member. However, mild steel, hard plastic, reinforced plastic, or the like may be used. For example, when attaching a non-slipping member made of mild steel to an iron bar, the rusting of the bar can be suppressed by coating the anti-slipping member with zinc, which has a higher ionization tendency than iron. And you may mix the anti-slip | skid microparticles | fine-particles in this zinc coating material. Also, when using plastics as a slip-preventing member, the slip-preventing member is heat-sealed to the rod, but the anti-slip particles are applied to the rod by pressurizing the slip-preventing member from the outer periphery before or after heat-sealing. It is good to make it bite.
[0023]
【Example】
As a structure for preventing the lateral displacement of the stabilizer φ30, a displacement preventing member for joining a pair of semi-annular members made of an aluminum material, having a plate thickness of 4 mm and a width of 17 mm was used. In addition, an alumina abrasive was used as the grinding grain. The plate thickness, plate width, grain size of the grinding grains, and dimensions of each semi-annular member before assembly can be changed in consideration of lateral displacement pressure and specifications. For example, the particle size of the alumina abrasive as the grinding grain was in the range of coarse particles # 46 to # 120 defined in JIS R611, and showed satisfactory results with respect to the required deviation load strength. If the particle size becomes rougher than this, the coating film on the surface of the rod material to be mounted may be excessively scratched, and conversely, if it becomes finer, the strength will decrease, so this particle size range is suitable as a structure for preventing lateral deviation of the stabilizer. It becomes a use condition.
[0024]
Here, when the required anti-slipping strength varies depending on the specifications on the stabilizer side, an appropriate anti-slipping strength can be obtained by adjusting the amount of anti-slip fine particles such as the alumina-based abrasive to be applied. . The management at this time can be performed by the ratio between the total surface area of the inner peripheral surface of the slip prevention member and the application area of the anti-slip fine particles.
[0025]
FIG. 5 shows a measurement of the lateral load-displacement relationship of this structure. From this graph, it can be seen that this structure has sufficient lateral deviation strength, which is much higher than the standard 2KN. Similar results can be obtained by using a silicon carbide abrasive as the non-slip particles instead of the alumina abrasive.
[0026]
【The invention's effect】
As is apparent from the above description, according to the rod-slip prevention structure of the present invention, the annular slip stopper is formed by joining the ends to each other so as to surround the rod and press-contacting the outer periphery of the rod. and member, and with a simple structure called Ru is interposed fine particles for preventing slippage between the inner peripheral surface of the outer peripheral surface and the displacement preventing member of the bar, the displacement preventing member is secured to firmly bars, bars Can be reliably prevented from shifting in the axial direction, sufficient durability and strength can be obtained, and automatic assembly is facilitated.
