An air spring with an air spring rolling bellows made of elastomer material with reinforcing layers embedded within the rolling bellows wall, the air spring being clamped in between a sprung and an unsprung mass, wherein the rolling bellows comprises, within its wall at a first bellows end, a tubular or cylindrical wall reinforcement which extends in a longitudinal direction of the rolling bellows and which is formed in addition to the reinforcing layers, said wall reinforcement extending over an end-side partial length of the rolling bellows and imparting such a dimensional stability to the rolling bellows there that, during operation, the rolling bellows rolls, by way of its wall parts located outside of the additional wall reinforcement, on the outer side of the end-side partial length, with the formation of a rolling fold.

Air spring having an air spring rolling bellows of elastomer material, wherein the air spring is clamped in between a sprung and unsprung mass, and the rolling bellows has at a first bellows end an air spring piston which is pot-shaped or tubular with walls which extend in the longitudinal direction of the rolling bellows and on which the rolling bellows rolls in operation with the formation of a rolling fold, wherein, starting from the first bellows end, the air spring piston extends axially over a partial length of the rolling bellows in the direction of the second bellows end and is designed as a sleeve which outwardly encloses the rolling bellows over the partial length, the part of the rolling bellows that extends beyond the partial length rolling on the outer surface of said sleeve in operation with the formation of the rolling fold.

Razvoj zračne vzmeti je močno povezan s kupčevimi in aplikacijskimi zahtevami, ki so vedno strožje. Vedno bolj pogosto se pri razvoju zračne vzmeti soočamo z neugodnimi kinematičnimi zahtevami, ki pri nekaterih obstoječih rešitvah predstavljajo problem snemanja gumenega meha iz odvalnega valja, kar onemogoči delovanje zračne vzmeti. Za ta namen smo predstavili in ovrednotili nove koncepte za rešitev tega problema, kjer smo ocenili, da je koncept zavihovanja odvalnega valja še najboljši. V programskem paketu Abaqus smo zato ta koncept simulirali, analizirali in ga primerjali z obstoječo rešitvijo. Izvedli smo simulacijo potrebne izvlečne sile in izbrane kinematike gibanja zračne vzmeti. Rezultate simulacij smo podprli tudi z eksperimenti na prototipnih vzorcih, kar potrjuje uspešnost simulacije in analize.
