【０００６】
【発明が解決しようとする課題】
しかしながら、従来のスタビライザ、特に、一体形スタビライザは、Ｕ字状の所望の形状に曲げることが困難である。一方、分割形スタビライザは、中空状のトーション部材２１Ａの一端とＩ形断面のアーム部材２１Ｂ，２１の一端との結合が難しく、しかも、その結合部が破損し易いという問題点があった。
【０００７】
したがって、本発明の目的は、所望の形状に簡単に組み立てることができ、しかも軽量化にすることができ、耐久性を大幅に向上することができる分割形スタビライザを提供するものである。
【０００８】
【課題を解決するための手段】
本発明に係る分割形スタビライザは、車両の横方向に延び、両端部にそれぞれ連結部材の取付け部を固定した中空状のトーション部材と、車両の縦方向に延び、一方の端部に締付部材の取付け部を固定し、他方の端部に目玉部材の取付け部を固定した２本の中空状のアーム部材と、ゴムなどで作成した円筒状の応力緩和材とを備え、上記締付部材の結合部と上記連結部材のリング状嵌合部との間に上記応力緩和材を設けて連結し、全体的にＵ字状に形成した分割形スタビライザにおいて、上記連結部材のリング状嵌合部につづみ状透穴を形成し、このつづみ状透穴に上記応力緩和材が圧入され、上記応力緩和材の中心穴には上記締付部材の結合部が挿入され、上記応力緩和材にはプレストレスが与えられているものである。
【０００９】
【発明の実施の形態】
図１は本発明に係る分割形スタビライザの一実施例を示す平面図であり、図２は図１の一部詳細な断面図であり、図３は図１に示す分割形スタビライザの分解した平面図であり、図４は図１のアーム部材の詳細を示す側面断面図である。図１〜図４において、２５は中空状のトーション部材であり、このトーション部材２５は車両の横方向に配置される。２６，２７は連結部材であり、この連結部材２６，２７はそれぞれリング状嵌合部２６Ａ，２７Ａと取付け部２６Ｂ，２７Ｂから構成され、このリング状嵌合部２６Ａ，２６Ｂにはつづみ状透穴２８（図３参照）が形成されている。また、この取付け部２６Ｂ，２７Ｂはそれぞれトーション部材２５の端部に溶接２９により固定される。３０，３１は中空状のアーム部材であり、このアーム部材３０，３１は車両の縦方向に配置される。
【００１０】
３２，３３は締付を保持する締付部材であり、この締付部材３２，３３はそれぞれ結合部３２Ａ，３３Ａ（図２，図３，図４参照）と取付け部３２Ｂ，３３Ｂから構成され、この結合部３２Ａ，３３Ａ（図２，図３，図４参照）にはネジ穴（図２，図３，図４参照）を設けている。また、この取付け部３２Ｂ，３３Ｂはそれぞれアーム部材３０，３１の一方の端部に溶接２９により固定される。３４，３５は目玉部材であり、この目玉部材３４，３５はそれぞれリング状車体側嵌合部３４Ａ，３５Ａと取付け部３４Ｂ，３５Ｂから構成され、このリング状車体側嵌合部３４Ａ，３５Ａには円筒状透穴３６（図３，図４参照）が形成されており、この円筒状透穴３６（図３，図４参照）には図示せぬ振動吸収部材を介して車体１（図５，図６参照）に固定される。また、取付け部３４Ｂ，３５Ｂはそれぞれアーム部材３０，３１の他方の端部に溶接２９により固定される。３７，３８はゴム、ウレタンなどの応力緩和材であり、この応力緩和材３７，３８は、たとえば円筒状に形成される。３９Ａ，３９Ｂは当金、４０Ａ，４０Ｂは締付けネジである。
【００１１】
なお、この応力緩和材３７，３８は、連結部材２６のリング状嵌合部２６Ａのつづみ状透穴２８に圧入されている状態では、その断面形状を図２に示すように、両端部分の圧縮は小さいが、中間（中心）部分の圧縮は順次、高く形成され、つづみ状になる。
そして、目玉部材３４，３５に上下方向の荷重Ｐ１（図１参照）がかかったときの捩りモーメント（上下方向の荷重Ｐ１（図１参照）×アーム部材３０，３１の長さ）によっても、つづみ状に圧縮された応力緩和材３７，３８は、充分に耐え、トーション部材２５に捩り力を発生させる強度を有するものである。
また、目玉部材３４，３５に横方向の荷重Ｐ２（図１参照）がかかったときの曲げモーメント（横方向の荷重Ｐ２（図１参照）×アーム部材３０，３１の長さ（図１参照））によって、締結部材３２，３３に発生する応力を、つづみ状に圧縮された応力緩和材３７，３８が減少させるような、適当な硬度（たとえば、ショワー硬度が８５度以上）を有する。
【００１２】
次に、上記構成の分割形スタビライザの組立て工程について簡単に説明する。まず、アーム部材３０の一方の端部に目玉部材３４の取付け部３４Ｂをたとえば溶接２９によって取り付けると共に、アーム部材３０の他方の端部に締付部材３２の取付け部３２Ｂを、たとえば溶接２９によって取り付ける。同様に、アーム部材３１の一方の端部に目玉部材３５の取付け部３５Ｂをたとえば溶接２９によって取り付けると共に、アーム部材３１の他方の端部に締付金具３３の取付け部３３Ｂを、たとえば溶接２９によって取り付ける。また、トーション部材２５の一方の端部に連結部材２６の取付け部２６Ｂをたとえば溶接２９によって取り付ける。同様に、トーション部材２５の他方の端部に連結部材２７の取付け部２７Ｂをたとえば溶接２９によって取り付ける。
【００１３】
次に、応力緩和材３７の中心穴に締付部材３２の結合部３２Ａを挿入し、この結合部３２Ａにこの応力緩和材３７を取り付ける。同様に、応力緩和材３７の中心穴に締付金具３３の結合部３２Ａを挿入し、この結合部３２Ａに応力緩和材３８を取り付ける。そして、上記トーション部材２５の一方の端部に取り付けた連結部材２６のリング状嵌合部２６Ａのつづみ状透穴２８にこの応力緩和材３７を圧入し、当金３９Ａを介して締付ねじ４０Ａを結合部３２Ａのねじ穴にねじ込んで固定する。同様に、上記トーション部材２５の他方の端部に取り付けた連結部材２７のリング状嵌合部２７Ａのつづみ状透穴２８にこの応力緩和材３８を圧入し、当金３９Ｂを介して締付ねじ４０Ｂを結合部３３Ａのねじ穴にねじ込んで固定する。このため、応力緩和材３７，３８は、それぞれリング状嵌合部２６Ａ，２７Ａのつづみ状透穴２８，２８により、プレストレスを与えることができる。
【００１４】
このように構成した分割形スタビライザは、目玉部材３４，３５に上下方向の荷重、および／あるいは横方向の荷重がかかったとき、連結部材２６、応力緩和材３７、締付部材３２から構成される結合部、および連結部材２７、応力緩和材３８、締付部材３３から構成される結合部は、確実に、トーション部材２５に捩り力を発生させることができ、スタビライザ効果を発揮することができる。
なお、従来の一体形スタビライザおよび本発明の分割形スタビライザ（ただし、応力緩和材３７，３８の硬度を９０度とした場合）について、応力解析（ばね定数、アーム部の最大曲げ応力、トーション部の最大捩り応力）をした結果は、表１の通りである。

また、トーション部材２５を直線状に形成したが、これに限定するものではなく、任意な形状に曲げ加工してもよいことはもちろんである。
また、溶接２９により取付けたが、これに限定せず、圧入してもよいことはもちろんである。
【００１７】
【発明の効果】
以上詳細に説明したように、本発明に係る分割形スタビライザによれば、所望の形状に簡単に組み立てることができ、しかも軽量にすることができる。
さらに、トーション部材の両端にそれぞれ固定した連結部材の端部とアーム部材の端部に固定した締付部材の端部との結合部には、ゴムなどの応力緩和材がプレストレスの状態で介在しているため、トーション部材に確実に、捩り力を発生させることができ、スタビライザ効果を発揮することができる。しかも、耐久性を大幅に向上させることができるなどの効果がある。

Next, the coupling portion 32A of the tightening member 32 is inserted into the center hole of the stress relaxation material 37, and the stress relaxation material 37 is attached to the coupling portion 32A. Similarly, the coupling portion 32A of the fastening bracket 33 is inserted into the center hole of the stress relaxation material 37, and the stress relaxation material 38 is attached to the coupling portion 32A. Then, the stress relieving material 37 is press-fitted into the continuous through hole 28 of the ring-shaped fitting portion 26A of the connecting member 26 attached to one end portion of the torsion member 25, and a tightening screw is inserted through the metal 39A. 40A is screwed into the screw hole of the coupling portion 32A and fixed. Similarly, the stress relieving material 38 is press-fitted into the joint-shaped through hole 28 of the ring-shaped fitting portion 27A of the connecting member 27 attached to the other end of the torsion member 25, and tightened via the abutment 39B. The screw 40B is screwed into the screw hole of the coupling portion 33A and fixed. For this reason, the stress relaxation materials 37 and 38 can give prestress by the joint-like through-holes 28 and 28 of the ring-shaped fitting portions 26A and 27A, respectively.
[0014]
The divided stabilizer configured as described above includes the connecting member 26, the stress relieving material 37, and the tightening member 32 when a vertical load and / or a lateral load is applied to the eyeball members 34 and 35. The coupling portion, and the coupling portion including the coupling member 27, the stress relaxation member 38, and the tightening member 33 can surely generate a torsional force on the torsion member 25, and can exhibit a stabilizer effect.
It should be noted that stress analysis (spring constant, maximum bending stress of the arm portion, torsional portion of the torsional portion of the conventional integrated stabilizer and the split-type stabilizer of the present invention (when the hardness of the stress relaxation members 37 and 38 is 90 degrees). The results of the maximum torsional stress are shown in Table 1.

Further, although the torsion member 25 is formed in a straight line shape, the present invention is not limited to this, and it is needless to say that the torsion member 25 may be bent into an arbitrary shape.
Moreover, although it attached by welding 29, it is needless to say that it is not limited to this and may be press-fitted.
[0017]
【The invention's effect】
As described above in detail, according to the split stabilizer according to the present invention, it can be easily assembled into a desired shape and can be reduced in weight.
Further, a stress relaxation material such as rubber is interposed in a prestressed state at the joint between the end of the connecting member fixed to both ends of the torsion member and the end of the fastening member fixed to the end of the arm member. Therefore, a torsional force can be reliably generated in the torsion member, and a stabilizer effect can be exhibited. Moreover, there is an effect that the durability can be greatly improved.
