Truck Air Springs for Extreme Temperatures
Truck Air Springs for Extreme Temperatures
ContiTech has launched Truck Air Springs for Extreme Temperatures. The temperature resistance requirements of air spring systems are becoming increasingly stringent. Extreme temperatures in particular present major challenges for developers and manufacturers. Standard materials do not withstand the extreme stresses. 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 hi-temp air springs for use in high temperatures above zero. With the new air spring, trucks are optimally equipped to operate in temperatures as low as -55°C. In extremely hot regions, the requirements on air springs in commercial vehicles are very different. Higher ambient temperatures and extreme atmospheric effects such as ozone and UV radiation accelerate the wear process. The installation conditions in the vehicle can further intensify this process: In particular, the proximity to the vehicle exhaust system places higher thermal stress on the air springs. Because of this, the wear of the rubber increases enormously, even in moderate climatic conditions. 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 hi-temp 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 hi-temp air spring offers twice the service life of a standard product in extreme temperatures of 80°C.
