Rubber air spring can be classified into three categories according to its shape: convoluted type, rolling lobe type and sleeve type. According to its sealing configuration, it can be classified into self- sealed air spring, clamping plates air spring, bead ring air spring and mixed type.
Rubber air spring is a rubber component with flexibility via the condensability of air. It is an elastomer made of polyester cloth layer, inner & outside rubber layer and steel rings after the process of modeling and vulcanization.
• Special surface rubber : protect its body, resist various external environment pollution and play the role of seal;
• High intensity skeleton layer : control tension, load pressure;
• Polarity endothecium rubber : seal indoor compressed air, bear air pressure.
