Rubber air spring
The air spring is filled with compressed gas in a rubber sealed container, and uses the compressibility of the gas to achieve its spring action. The stiffness of this spring is variable, because when the load acting on the spring increases, the gas pressure in the container increases, and the stiffness of the spring increases. On the contrary, when the load decreases, the air pressure in the spring decreases and the stiffness decreases, so it has ideal elastic characteristics.
Air springs are widely used and are irreplaceable in vehicle applications, automation technology, conveyor systems, agricultural machinery, food industry, paper and textile equipment, pantograph drives, sawing machinery, drilling machines and forming press vehicles. The role of. The market has been monopolized by European and American companies, and imported rubber air springs are used in China.
Our company’s rubber air springs have been successfully researched on heavy-duty trucks and have successfully flexed more than 3 million times, exceeding EU standards, and bursting pressure: 28.2 bar, exceeding EU standards: 25 bar.
At present, ContiTech of Germany and Firestone of the United States monopolize the rubber air spring market of more than 90% of domestic OEMs, and the prices are high. The annual domestic production of heavy trucks is more than 1 million, and each main suspension requires 8 sets of rubber air springs. The annual demand is more than 10 million sets. In addition, the old springs are aging and replaced in an average of 3-6 years. The superimposed demand is huge, while the domestic private rubber air The production capacity of spring enterprises is extremely limited (because they cannot meet relevant quality standards).

How is tear resistance
The impact compressive strength increased and exceeded the valley value of about 2 million. At this time, the content increases and the impact compressive strength decreases. This is because the molecular structure chain temporarily blocks its light crystallization effect, so there is a large amorphous region in the biological macromolecule, which can digest and absorb a large impact kinetic energy.
