Claim Text:
1. An air spring assembly for a motor vehicle, comprising an air spring, an air spring bellows, an air spring cover, and a rolling piston, wherein the air spring bellows is a tubular rolling bellows, wherein the air spring bellows is arranged concentrically about a central longitudinal axis of the air spring, between the air spring cover and the rolling piston, wherein the air spring bellows has a first partial air spring bellows and a second partial air spring bellows, wherein the first partial air spring bellows partially encloses an air volume at the end of the air spring on the cover side, wherein the second partial air spring bellows encloses an air volume at the end of the air spring on a rolling piston side, wherein the first partial air spring bellows has a first embedded textile reinforcement, wherein the second partial air spring bellows has a second embedded textile reinforcement, wherein the first textile reinforcement has first reinforcing threads, a preferred axis of which extends parallel or nearly parallel to the axis of the central longitudinal axis of the air spring, wherein the second textile reinforcement has second reinforcing threads, a first preferred axis of which extends obliquely to the longitudinal axis of the air spring and a second preferred axis of which extends obliquely to the longitudinal axis of the air spring, wherein the first and the second preferred axis are at an angle to each other, wherein the air spring bellows includes three separate areas arranged in an axial direction of the air spring bellows, a first area of the three areas including the first partial air spring bellows and not the second partial air spring bellows, a second area of the three areas including both the first partial air spring bellows and the second partial air spring bellows arranged in overlapping fashion in a radial direction of the air spring bellows, and a third area of the three areas including the second partial air spring bellows and not the first partial air spring bellows, and wherein the first partial air spring bellows has an elastically deformable counterholder on an innermost surface thereof, wherein the first partial air spring bellows has a system of folds, wherein the system of folds comprises at least two folds, wherein the at least two folds have two apex lines and a common trough line when viewed from the central longitudinal axis of the air spring, wherein the system of folds comprises a constriction of the first partial air spring bellows to form the one trough line, wherein the constriction is designed to accommodate a ring or a cord bandage, wherein the constriction is designed in such a way that the ring can be accommodated positively in the axial direction, and wherein the elastically deformable counterholder is positioned at the at least one trough line of the system of folds, wherein the counterholder is designed to accommodate the ring positively.
