■When vulcanized or used as a product, the reinforcing cord (11) will shift as shown in Figure 2 due to the tension and compression of the air spring. During compression, it shifts from figure (a) to figure (C)).
即ち従来にあっては下記のような問題点がある。That is, the conventional method has the following problems.

性としては引張強さ200 Kglol以」二静的剪断
弾性率10〜3000 Kglolの範囲である。As shown in FIG. 3, the present invention is an air spring made solely from a liquid material that becomes an elastomer by crosslinking the air spring body (1). The physical properties of the ex-1-mer after crosslinking include a tensile strength of 200 kgl or more and a static shear modulus of 10 to 3000 kgl.
その製造方法は次のように行なう。気泡を除いた液状材
料を金型に注型し、架橋させた後脱型する。The manufacturing method is as follows. The liquid material from which air bubbles have been removed is poured into a mold, crosslinked, and then removed from the mold.
上記気泡の除去は常温であるいは加熱しながら減圧上放
置、三本ペイントロール通し等を行なうことにより出来

なお補強用コードを持たないゴムだけの空気ばねは実際
の製品には存在しない。というのは従来使用されていた
ゴムでは弾性率、および強度が低すぎるためである。Note that air springs made of only rubber without reinforcing cords do not exist in actual products. This is because the elastic modulus and strength of conventionally used rubbers are too low.
