ABSTRACT:
DESCRIPTION
The invention relates to a pneumatic suspension system consisting of
at least one bellows made of elastomer material and provided with reinforcement linings, if need be;
a cover comprising a lower zone, on which the upper end of the bellows is secured by means of a clamping ring or the like, a median zone, and an upper zone which is connected at the same time with a connecting component, in particular with a structural component integral with the body of the vehicle; as well as
a pneumatic piston, on which the bottom end of the bellows is secured by means of a clamping ring or the like as well, with the pneumatic bellows being capable of rolling off on the outer wall of said piston.
Such a pneumatic suspension system is described, for example in published document DE-A-36 43 073.
Based on the prior art of a pneumatic suspension system outlined above, the present problem is to elastically support the milling forces generated in connection with the elastic movement of pneumatic bellows, and to isolate such forces from the body of the vehicle or other structural components in such a way that the driving comfort is enhanced.
Now, said problem is solved according to the characterizing part of patent claim
1
in that
the pneumatic suspension system is equipped with a pleated structure bearing extending around the pneumatic cover in the form of a ring within its median zone, whereby the rolling pleat developing within the zone of the top end of the pneumatic bellows is elastically supported on said pleated structure bearing, and whereby the pleated structure bearing is in turn supported on a structural component, the latter being a part element of the pneumatic cover, a connecting component, or an additional structural component.
Useful embodiments of the pneumatic suspension system as defined by the invention are specified in claims
