Rolling bellows-air spring for motor vehicle, particularly passenger car, has closure mechanism for air flow opening, which is mounted in partition wall and is electrically switched between open state and closed state

摘要

The rolling bellows-air spring (1) has rolling piston (3), which is connected with an upper part (2) having a partition wall (7) through an air spring bellow (4). The partition wall separates a main air chamber (8) limited by the air spring bellow and the rolling piston from an additional air chamber (9) formed in the upper part. The partition wall has an air flow opening (11) between the main air chamber and the additional air chamber. A closure mechanism for the air flow opening is mounted in the partition wall and is electrically switched between an open state and a closed state.
