The double U-bellows pneumatic spring (2) consists of a cover fastened to the chassis of the vehicle and to which is attached an upper roll piston (6) and a lower roll piston (8) installed with variable spacing in relation to it. One end of a respective double U-bellows is clamped pressure tight on the lower end of the upper roll piston and on the upper end of the lower roll piston. In the region of the upper bellows fold (10a) between the upper roll piston and U-bellows use is made of a foam component (16) to act as a dirt trap. |
