Due to growing demand for driving comfort in cars, Air Springs are increasingly being installed in upper mid-range segment. The stiffness of an Air Spring is significantly influenced by its enclosed air volume, larger volumes lead to softer spring systems. The decreasing installation space in modern car axles directly contradicts the demand for a higher level of comfort. Thus, development is faced with the challenge of integrating springs into ever smaller installation spaces. This results in the task of reducing the volume of Air Springs while maintaining the same required stiffness. One solution to make an air spring smaller is to insert an adsorbent. Adsorptive materials such as activated carbon, can bind additional amounts of air in their pores causing the springs to behave as if their effective volume had been increased. This way, softer properties can be achieved without changing the geometric dimensions of the spring. The insertion of adsorbents in Air Springs is relatively new which is why there have been few studies on this topic. Although this technology has been installed in commercially available vehicles, there are no relevant studies in the literature that describe the effectiveness of activated carbon in terms of Air Spring stiffness.
