Abstract
The invention relates to a pneumatic-suspension assembly, consisting of at least one pair of pneumatic-suspension bellows (2), a cover (5) comprising a first connection area (6), a rolling piston and an external guide (10). The inventive pneumatic-suspension assembly is characterized in that a continuous pleated bearing (11) connects the cover (5) to the external guide (10) and surrounds the pneumatic suspension bellows (2), whereby the pleased bearing comprises the following components: a first retaining part (13), which is fixed together with the corresponding end of the bellows (12) to the cover (5) in the first connection area (6); a second retaining part (14), which encompasses at least one partial area of the outer surface of the eternal guide (10); and a system of pleats (1), which is located between the first and second retaining part (13, 14) and which comprises at least a first and a second pleat (15, 16) that run towards the interior of the assembly, forming at least one contraction (17). The pneumatic suspension bellows (2) are adapted to the contour of contraction and a supporting ring (18) sits inside the contraction
