Abstract: A pneumatic suspension system comprising: a pneumatic suspension bellows made of an elastomeric material which encloses an air chamber whose volume varies, with an embedded strengthening support; a pressure reservoir having an outer diameter on which one end of the pneumatic suspension bellows is fastened by a clamping ring; and a pneumatic suspension piston having an outer diameter on which the other end of the pneumatic suspension bellows is also fastened by a clamping ring, and having a roll-off piston on whose outer wall the pneumatic suspension bellows can roll off while forming a first rolling fold. The pressure reservoir has a contoured roll-off surface outside of the first fastening area. The roll-off surface is provided for a second rolling fold which rests against the roll-off surface and can roll off in a limited manner compared to the first rolling fold.

Abstract: The invention relates to a pneumatic spring system, comprising at least the following components, namely air-spring bellows, an air-spring cover, an air-spring piston and an external guide. The inventive pneumatic spring system is characterized in that the external guide consists of a plastic material with a solid support embedded therein.

Abstract: The invention relates to a pneumatic spring arrangement consisting of at least the following components: pneumatic spring bellows, a pneumatic spring cover, a pneumatic spring piston and a vibration damper having a container pipe and a piston rod. The inventive pneumatic spring arrangement is characterized in that the pneumatic spring piston is provided with an integrated clamping lock which consists of an outer ring body and an inner ring body. The bodies can be plugged into one another. The outer ring body comprises a collar and at least one spring arm which is provided with a barb. The inner ring body comprises an outer ring and an inner ring which are connected to each other in such a way that at least one plug aperture is provided for receiving the barb of the spring arm in a catching manner.

Abstract: The invention relates to a pneumatic suspension system comprised of at least the following pneumatic suspension components, namely of: (a) a pneumatic suspension bellows made of an elastomeric material which encloses an air chamber whose volume varies, and provided, for the most part, with an embedded strengthening support; (b) a pressure reservoir comprising a first fastening area with an outer diameter on which one end of the pneumatic suspension bellows is fastened by means of a clamping ring, whereby the outer diameter includes the clamping ring, and; (c) a pneumatic suspension piston comprising a second fastening area with an outer diameter on which the other end of the pneumatic suspension bellows is also fastened by means of a clamping ring, whereby the outer diameter also includes the clamping ring, as well as comprising a roll-off piston with an outer diameter on whose outer wall the pneumatic suspension bellows can roll off while forming a first rolling fold.

Abstract: A strut with an air-filled cushion and comprising a bellows (1) that rolls down over a surface (3), a hydraulic dashpot accommodated inside the bellows or surface, a piston rod (5) that travels in and out of the dashpot, and an upper and lower closing and fastening component provided with seals, whereby the seals are O rings. The object is a simple approach to sealing the interface between the closing and fastening components and the dashpot that will still allow a reliable seal by means of O rings. Each O ring (9 & 10) is accordingly accommodated in a recess both radially and axially open at one side in the upper component, rests radially against the lower component, and is fixed and/or tensioned axially by a ring (14) fastened to the upper component or by a disk (12).

Abstract: A composite fiber reinforced plastic frame is provided wherein a core material at least partially formed from the continuous wrapping of roved layers of glass fiber impregnated with a catalyzed thermosetting resin within a corrosion resistant liner and the frame is reinforced at the corners.
