Air-spring assembly

An air spring assembly comprising:

• (a) an air spring bellows made of elastomer material that encloses an air spring inner chamber having an elastic volume;
• (b) air spring cover on which the one end of the air spring bellows is secured;
• (c) an air spring piston comprising
• (i) a face area arranged opposite the air spring cover;
• (ii) a piston edge defining the face area on the outer side, whereby the other end of the air spring bellows is turned inside out over the edge of the piston and merges into a mostly thickened fastening zone, which in turn is secured in a clamping manner on the air spring piston within the face area of the latter by means of a tying element;
• (iii) a lateral roll-off surface on which the air spring bellows is capable of rolling off, forming a rolling fold;
• (iv) a base area;
• and
• (d) a buffer that is arranged within the face area of the air spring piston;
• wherein the tying element for tying the air spring bellows to the air spring piston and the buffer in the form of a securing and buffering combination system are one single structural component made from an elastomeric or plastic material;
• and
• wherein with respect to the base area of the air spring piston, the height (H) of the piston edge is smaller than the height (H′) of the edge of the fastening zone of air spring bellows facing the air siring inner chamber.
