It has been conventional practice to connect the lower arm L and suspension member S through a bush-like rubber shock absorber. It has a structure in which rubber is interposed between the cylinders, and the vibration-proofing function is supported by the rubber, and the inner cylinder and outer cylinder function to maintain mechanical strength. In order to increase the fitting force with the member, it is generally made of a metal material such as iron, and is press-fitted into the through hole of the mating member with a large pressing force and fixed.
ところが、ゴム緩衝体が相手側結合部材の貫通
孔から抜け落ちないようにするには1000〜1200Kg
もの高圧力で行わなければ金属相互間の摩擦力を
保つことができないという問題があつた。 However, in order to prevent the rubber buffer from falling out of the through hole of the mating member, it requires 1000 to 1200 kg.
There was a problem in that the frictional force between the metals could not be maintained unless it was performed under extremely high pressure.
また、これよりも軽い力で圧入しようとすれ

る。 As described above, the present invention was developed in view of the fact that conventional rubber shock absorbers have various problems and still no improvement has been seen. The outer cylinder is made of hard synthetic resin, an outward facing flange is provided at the opposite end of the cylindrical body, and a maximum outer diameter part is provided between the central part of the cylindrical body and this outward facing flange, and is characterized by a configuration in which it is formed into a tapered cylinder whose outer diameter slightly decreases from the maximum outer diameter portion toward the outward flange side, and thus,
The elasticity and wedge action created by the press-fitting of the tapered cylindrical portion are sufficient to prevent it from coming off.

なつている。 The rubber cushioning body 1 comprises an inner cylinder 5 through which an attachment member such as a bolt (not shown) is inserted, an outer cylinder 3 which concentrically surrounds the inner cylinder 5 and is fitted onto a support member 2 which is attached to a connecting member such as a suspension arm, and an elastic material 4 such as rubber which is interposed between the two cylinders 5, 3 and integrated with them.
内筒５は金属を素材として一定外径の筒体に形

とする筒体の反挿入側端部に外向き鍔６を縁設せ
しめている。 The inner cylinder 5 is made of metal and formed into a cylindrical body of a fixed outer diameter, while the outer cylinder 3 is made of hard synthetic resin and has an outward flange 6 formed on the end opposite the insertion side.

形成している。 The outer cylinder 3 further includes a central part of the cylinder body and an outward facing collar 6.
A maximum outer diameter portion 3b is provided between the outer diameter portion 3b and a tapered cylindrical portion 3a whose outer diameter slightly decreases from the maximum outer diameter portion 3b toward the outward facing collar 6 side. Also,
The outer diameter of the insertion side cylindrical portion 3c is made smaller than the other portions.
この場合、前記テーパ筒部３ａは例えば1/50程

成樹脂が選定されるものである。 Note that the synthetic resin that is the material of the outer cylinder 3 includes polyamide resin (6 nylon, 66 nylon,
(nylon MXD6, etc.), polyester resin (polyethylene terephthalate, polybutylene terephthalate), polyphenylene sulfide resin, polyimide resin, polyamideimide resin, polyether sulfone resin, polycarbonate resin, polyacetal resin, modified polyphenylene oxide resin,
Polyarylate resins are preferred, and mixtures thereof are also preferred. The above-mentioned various synthetic resins were selected from the viewpoint that this resin needs to be a synthetic resin that can satisfy the condition of having sufficient rebound elasticity at the pressed part of the outer cylinder 3 against radial pressure after molding. It is something that
なお、上記外筒３は上記各合成樹脂の単一構造

に、対向する両側壁部２ａ，２ｂの所定位置に、
前記外筒３のテーパ筒部３ａと挿入側筒部３ｃと
をそれぞれ圧嵌挿し得る孔７ａと７ｂとを各々穿
設して有している。 For the rubber shock absorber 1 having the above-described structure, the support member 2 that supports the rubber shock absorber 1 corresponds to the lower arm L shown in FIG. The material is made of steel, for example, and as shown in FIGS.
Holes 7a and 7b are formed into which the tapered cylindrical portion 3a and the insertion side cylindrical portion 3c of the outer cylinder 3 can be press-fitted, respectively.

筒３を圧嵌入した場合に、テーパ筒部３ａと挿入
側筒部３ｃとがそれ等の許容弾性限界内で縮径し
て各孔７ａ，７ｂに嵌合し得るようになつてい
る。 The holes 7a, 7b correspond to the respective cylindrical portions 3a, 3c.
The diameter of the hole is slightly smaller than that of the cylinder, and when the outer cylinder 3 is press-fitted, the diameter of the tapered cylinder part 3a and the insertion side cylinder part 3c is reduced within their allowable elastic limits. It is designed so that it can be fitted into each hole 7a, 7b.
上述の構成になる支持装置はゴム緩衝体１と支
持部材２とを、外筒３、両孔７ａ，７ｂ間の嵌合
によつて一体化されるが、その際、両方の筒部３
ａ，３ｃが対応する各孔７ａ，７ｂ内で弾性を存
し縮径しているので、それ等接触面での摩擦力は
相当に大であつて、これがゴム緩衝体の抜け落ち
に対し防止効果を奏する。 In the support device configured as described above, the rubber buffer body 1 and the support member 2 are integrated by fitting between the outer cylinder 3 and both holes 7a and 7b.
Since the holes a and 3c have elasticity and are reduced in diameter within the corresponding holes 7a and 7b, the frictional force at their contact surfaces is quite large, and this has the effect of preventing the rubber buffer from falling off. play.
なお、この場合の圧嵌入に要する力は外筒が金
属製である従来のゴム緩衝体が1000〜1200Kgを要
していたのに対して、これと同等の抜け落ち防止
機能を発揮させるには約800Kgであり、かつ抜け
落ちに要する力は1000〜1200Kgとなることが実験
により確認された。 In addition, in this case, the force required for press-fitting was 1000 to 1200 kg for conventional rubber shock absorbers whose outer cylinders were made of metal, but in order to achieve the same ability to prevent falling out, it required approximately 1000 to 1200 kg. 800Kg, and it was confirmed through experiments that the force required to fall off was 1000-1200Kg.
この抜け落ち防止効果は、前述する摩擦力の増
強によるだけでなく、最大外径部３ｂが縮小して
前記孔７ａを通り抜けた後に原形に復する結果、
孔７ａの径よりも大きくなつて掛合作用をなすと
共に、テーパ筒部３ａの楔作用により該テーパ筒
部３ａと、前記外向き鍔６とで孔７ａを挟みつけ
る現象とが相俟つて抜け落ち防止に対しより有効
に作用しているからと考えられる。 This falling-off prevention effect is achieved not only by the aforementioned increase in frictional force, but also by the fact that the maximum outer diameter portion 3b shrinks and returns to its original shape after passing through the hole 7a.
The hole 7a becomes larger than the diameter of the hole 7a and acts as an engaging action, and the wedge action of the tapered cylindrical portion 3a causes the hole 7a to be sandwiched between the tapered cylindrical portion 3a and the outward facing flange 6, thereby preventing the hole 7a from falling out. This is thought to be because it acts more effectively on
本考案は叙上の構成ならびに作用を有するもの
であつて、ゴム緩衝体１の外筒３を硬質合成樹脂
から形成しているので、従来の鋼製に比して成型
が容易であるし、軽量化がはかれると共に防錆に
すぐれた性能を発揮する。 The present invention has the above-mentioned structure and function, and since the outer cylinder 3 of the rubber shock absorber 1 is made of hard synthetic resin, it is easier to mold than conventional steel. It is lightweight and exhibits excellent rust prevention performance.
しかも硬質合成樹脂の持つ弾性を利用している
ので、取付時の圧入力を鋼鉄製外筒を有する従来
のものよりも軽減することが可能で作業が簡単に
行える。 Moreover, since it utilizes the elasticity of hard synthetic resin, the pressing force during installation can be reduced compared to conventional products with a steel outer cylinder, making the work easier.
また、前述するように摩擦力および外向き鍔６
寄りのテーパ筒部分３ａが有する楔作用と、外向
き鍔６との協動により成される挟持作用が相乗的
に働く結果、より一層抜け難くなる効果が奏され
る。 In addition, as mentioned above, the frictional force and the outward flange 6
As a result of the wedge action of the tapered cylindrical portion 3a on the side and the clamping action achieved by cooperation with the outward facing collar 6 acting synergistically, the effect of making it even more difficult to come off is achieved.
