Abstract:
A pneumatic spring system comprising:(a) a pneumatic spring cover, (b) a pneumatic spring piston comprising: (i) a face area arranged opposite said pneumatic spring cover; (ii) a lateral roll-off surface; and (iii) an end zone on an end of said piston farthest removed from the face area; (c) a pneumatic spring bellows connecting said pneumatic spring cover and said pneumatic spring piston with each other; (d) a vibration damper comprising: (i) a container tube; and (ii) a piston rod connected with a core area of said pneumatic spring cover and slidably immersible in the container tube; (e) at least one backpack module projecting sideways beyond an outer periphery of the end zone of said pneumatic spring piston and arranged laterally on the container tube to form with the container tube a maximum outer diameter; (f) a protective sleeve comprising (i) a fold-shaped center part; (ii) a first connection area having a first inside diameter, said first connection area being secured to a portion of the pneumatic spring system other than said pneumatic spring piston or said vibration damper; and (iii) a second connection area having a second inside diameter, said second connection area being connected with the end zone of the pneumatic spring piston or the container tube or both, being located between the backpack module and the first connection area, and not being rotation-symmetrical with respect to a center axis of said protective sleeve; wherein said first and second inside diameters have a size so that said protective sleeve can be pushed over said backpack module, the excess clear space within said second circumferential direction, with formation of a maximum inside diameter connection area can be filled with an adapter element in a compensating manner, and the adapter element can be closed by a closing system to form a ring-shaped structure extending around the end zone of the pneumatic spring piston or the container tube or both.
