Abstract:
A pneumatic suspension system (1) consisting of at least the following components,a pot-shaped pneumatic suspension cover (2) having a damping bearing (14) integrated in its core area; a pneumatic suspension piston (3) comprising a face area (4) located opposite the pneumatic suspension cover (2); a lateral roll-off surface (5); and an end zone (6) that is removed farthest from the face area (4); a pneumatic suspension bellows (7, 7â€²) made of elastomer material, which bellows connects the pneumatic suspension cover (2) and the pneumatic suspension piston (3) with each other with the use of fastening means, and encloses an interior space (9) of the pneumatic suspension system with an elastic volume, whereby the pneumatic suspension bellows is capable of rolling off on the roll-off surface (5) of the pneumatic suspension piston (3) with formation of a first pneumatic suspension loop (8), and whereby, furthermore, the pneumatic suspension is provided with an embedded reinforcement in the form of an axial bellows (7) or a cross-layered bellows (7â€²), whereby an external guide (10) is present when an axial bellows is employed; a vibration damper (11) comprising a container tube (12) that is surrounded by the pneumatic suspension piston (3) at least by sections and has a lateral tie-up zone forming jointly with the end zone (6) of the pneumatic suspension piston (3) a sealing joint (16), a piston rod (13) connected with the core area of the pneumatic suspension cover (2) and the damper bearing (14) in a fixed manner, said piston rod immersing in the container tube (12) in a sliding manner; and a chassis tie-up (19) with tie-up points (20, 21) for the tie-up to the container tube (12) of the vibration damper (11), and to the chassis; and an articulated component (22, 22â€²) is mounted on the pneumatic suspension cover (2) within the closer proximity (A) of the tie-up of the pneumatic suspension bellows (7, 7â€²), said articulated component allowing swivel movements specifically with formation of a second pneumatic suspension loop substantially extending in the radial direction.
