この発明は、コイルスプリングの改良に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in coil springs.
コイルスプリングは、自動車の懸架装置などに用いられ
ている。Coil springs are used in automobile suspension systems and the like.
従来のコイルスプリングは、断面が円形の主として特殊
鋼製の丸棒を熱間処理によりコイル状に巻いて作ってい
た。Conventional coil springs are made by hot-treating a round bar made of special steel and winding it into a coil with a circular cross section.
そのような既存の技術においては、コイルスプリングの

コイルスプリングの長さが長くなると、これを自動車の
懸架装置に利用した場合に、次のような欠点が生じた。In such existing technology, in order to ensure the amplitude of the coil spring (referring to the difference between the length in the unloaded state and the length in the most compressed state; the same applies hereinafter) to a certain length, the following is necessary. The unloaded length of the coil spring is required as expressed by the formula: z1=nd+J, J=(
nl ) △ When the length of the l-pitch open-lid coil spring becomes longer when the coil spring is not loaded, the following drawbacks occur when this coil spring is used in an automobile suspension system.
１、コイルスプリングの支持点が高くなって懸架性が不
安定になるとともに、伸縮が助長さへピッチング、ロー
リング等の揺れを大きくする。1. The support point of the coil spring becomes high, making the suspension unstable, and the expansion and contraction increases pitching, rolling, and other shaking.
２、弾発によるスプリング自体の移動質量が大きくなる
ため、慣性力の発生が大きくなり、スプリングの動きが
緩慢・鈍重で、振動を敏しょうに吸収できない。2. Since the mass of the spring itself that moves due to the rebound increases, the generation of inertial force increases, making the spring movement slow and heavy, and vibrations cannot be absorbed quickly.
３、スプリングを保持するための軸その他の部材が長大
化し、車体重量を大きくする。3. The shaft and other members for holding the spring become longer, increasing the weight of the vehicle.
これらの欠点は、さ小なものとして看過できない程、大

欠陥は、急ブレーキ又は急カーブの際、進行方向又は回
転方向の外側へ必要以上にのめり込む現象となって現れ
る。それは従って車の安全性や乗り心地にも関連する。These shortcomings are too significant to be overlooked as trivial. That is, the first point and the second point are related to driving performance, and this tendency becomes particularly noticeable when driving at high speeds, when driving on curves, or when driving on rough roads. Among other things, this defect appears as a phenomenon in which the vehicle falls more than necessary to the outside in the direction of travel or rotation during sudden braking or sharp turns. It therefore also relates to vehicle safety and ride comfort.
また、第３点については、自動車の燃料消費量の低減上
の最大課題である車体重量の軽減に抵触する。Moreover, regarding the third point, it conflicts with the reduction of vehicle weight, which is the most important issue in reducing fuel consumption of automobiles.
この発明は、そのような従来のコイルスプリングの欠点

、この発明のコイルスプリングは、その素材の断面をだ
円又はそれに近い形状にしたものである。The present invention solves the drawbacks of such conventional coil springs. To explain this with reference to the drawings, the coil spring of the present invention has a material whose cross section is an ellipse or a shape close to an ellipse.

2: Non-negative vertical width of the coil spring of the present invention (minor axis of an ellipse or a shape close to it) S: Amplitude of the coil spring △S: Lid pitch opening when the coil spring is not loaded. The length tl) of the coil spring of the present invention and the length t2) of the coil spring of the present invention are determined by the number of turns (11) of the coil spring, the amplitude (S) of the coil spring, and the length of the coil spring when no load is applied. 1
Under the condition that the open lids (ΔS) of the pitches are all equal, the following relationship occurs.
ｔ２−１＋ ＝ ｎ （ｄ−ｂ ）
つまり、本発明のコイルスプリングは、従来のコイルス
プリングよりその長さをｎ（ｄ−ｂ）だけ短くすること
ができる。t2-1+ = n (d-b) In other words, the length of the coil spring of the present invention can be made shorter by n(d-b) than the conventional coil spring.
勿論、そのような素材の形状変更（断面を円からだ円又

さをｎ（ｄ−１））だけ短くすることができることを証
明する。Of course, even when changing the shape of the material (from a circle to an oval or a shape close to it), the strength of the spring must not be changed. This can be solved without any problems by making it equal to the area of the circle and the ellipse or a shape close to it. There is a relationship d>b between them, which proves that the length of the coil spring of the present invention can be made shorter by n(d-1)) than the conventional coil spring.
このようにしてこの発明のコイルスプリングはこれを自
動車の懸架装置に用いた場合に、次のような効果がある
。Thus, the coil spring of the present invention has the following effects when used in an automobile suspension system.
１、コイルスプリングの支持点が低くなって懸架性が安
定化するとともに、伸縮がかなり抑制されて、ピッチン
グ・ローリング等の揺れを減少する。1. The support point of the coil spring is lowered, making the suspension more stable, and expansion and contraction are considerably suppressed, reducing vibrations such as pitching and rolling.
２、弾発によるスプリング自体の移動質量が小さくなる
ため、慣性力の発生が小さくなり、スプリングの動きが
迅速・軽快で、振動を敏しょうに吸収する。2. Since the mass of the spring itself that moves due to the rebound is reduced, the generation of inertial force is reduced, and the spring moves quickly and lightly, absorbing vibrations quickly.
３、スプリングを保持するための軸その他の部材が短小
化し、車重を軽くする。3. The shaft and other members for holding the springs are shortened and the weight of the vehicle is reduced.
それらの特質によって、この発明は、車の走行性能殊に
高速走行、曲線走行及び悪路走行等のそれを改善すると
ともに、従来の欠陥であった急ブレーキ又は急カーブの

力少なくし、走行時の安全性及び乗心地を高め、併せて
燃料消費量の低減に効果がある。Due to these characteristics, the present invention improves the driving performance of a vehicle, especially in high speed driving, curve driving, rough road driving, etc., and also improves the driving direction or direction during sudden braking or sharp curves, which was a conventional defect. This is effective in minimizing the possibility of the vehicle turning outward in the direction of rotation, increasing safety and ride comfort during driving, and reducing fuel consumption.
