Abstract
The invention relates to an air-spring system (1), which is at least comprised of a cover (2), a roll-off plunger (3) and air-spring bellows (4) that are made of an elastomeric material and that are in most cases provided with an embedded stabilizing support, the two bellows ends being fastened to the cover and to the roll-off plunger, whereby the air-spring bellows enclose a volume-elastic air chamber while forming two loops (7, 8). The first loop (7) is adapted to glide on the outer wall of the roll-off plunger (3) and the second loop (8) communicates with a roll-off section of the cover (2). The inventive air-spring system (1) is further characterized in that the second loop (8) rests on the cover (2) only on two points (11) and rolls off via said points of support (11) when the angle of the air spring bellows (4) is modified by the deflection and the rebound of the roll-off plunger (3).
