EVEN (Qingdao Guoxiang Yiwen Rubber Technology Co., Ltd.) supplies high-performance reversible style (rolling lobe) air springs for bus and coach chassis suspension systems. Engineered with specialty rubber and the world-first "Liquid Gold" material, our reversible sleeve air springs deliver ultra-long fatigue durability and wear resistance for city buses, intercity coaches and high-end passenger transport applications.
Key Features
Structural topology optimization - optimized material distribution reduces stress concentration; modular segmentation with reinforced end sections and a flexible central buffer achieves the ideal balance of lightweight and strength.
Specialty rubber + "Liquid Gold" material - the world-first liquid-phase mixing compound delivers ultra-long fatigue durability and wear resistance.
Ultra-strong bonding technology - advanced rubber-to-cord adhesion improves bonding performance by 30%-50% compared with conventional products.
Advanced manufacturing - produced on a fully automatic winding production line with precise calendering, processing and adhesion control, ensuring consistent quality.
Full lifecycle traceability - every air spring is traceable from raw material to finished product through the Eco-Rubber Cloud system with MES, WMS and ERP integration.
Rigorous testing - each product passes 80°C and -40°C vertical durability tests and 1/4 suspension durability tests (inflation pressure 0.7 MPa, amplitude ±50 mm, frequency 2.5 Hz, per GB/T13061).
Applications
