The temperature resistance requirements of air spring systems are becoming increasingly stringent. Extreme temperatures in particular present major challenges for developers and manufacturers. Extremes impose high requirements on vehicle components. Standard materials do not withstand the extreme stresses. For this reason, ContiTech Air Spring Systems has brought two new types of air spring onto the market for its customers in commercial vehicle original equipment: air springs from the Arktis series for use in especially cold areas and high-temperature air springs for use in high temperatures above zero.
ContiTech has developed a cold-resistant air spring for semi-trucks. The key basis for the cold-resistant air springs is the special rubber compound used. ?Conventional air springs lose their elasticity at low sub-zero temperatures and can develop leaks,? explained, Diethelm Bauch, Head of Commercial Vehicle Original Equipment at ContiTech Air Spring Systems. ?This is why we developed a compound and put it through rigorous testing in the cold chamber. With the new air spring, trucks are optimally equipped to operate in temperatures as low as -55-?C,? he added.
To slow down the process and guarantee a long service life even in high temperatures, ContiTech has developed an air spring for high-temperature applications - the high-temperature air spring. It is based on a compound comprising chloroprene rubber (CR) as the main component and is marked with the symbol of a sun. ?Tests in a climate chamber have shown that the new high-temperature air spring offers twice the service life of a standard product in extreme temperatures of 80-?C,? said Bauch.
