Pneumatic suspension and dampening device

The upper cover (13) of the first air spring (4) is connected by a rod (14) to the lower rolling-seal piston (8) of the second air spring (5). This rod is located concentrically inside the two working chambers (6, 7) of the air springs (4, 5), and passes through the cover (12) of the second air spring (5). This (5) is guided within a hollow cylinder (9), through which it is solidly connected to the wheel suspension system.
