Technological progress has been made after material innovation.

The main components of the electronically controlled air shock absorber are rubber air spring, shock absorber and solenoid valve. The design life of rubber partis 5 years. How to solve the durability and service life of the shock absorber is the technical point that the technical department has been tackling, and the floating piston of the shock absorber is the key component.

After the demonstration and a large numberof tests, we have made a major technical breakthrough in the floating piston process of the shock absorber, so as to improve the service life of the electric control air shock absorber, solve the key and difficult problems, and increase the service life of the shock absorber to more than 3 million times.
