Pneumatic spring unit for e.g. passenger car, has covering fastened at external periphery and outside upper rolling region of spring rolling bellows by clamping ring, which produces circulating constriction at spring rolling bellows
The spring unit (1) has a rotationally symmetric protective covering (9) formed with a flexible wall in a longitudinal direction of the spring unit. The covering is fastened at an external periphery of a pneumatic spring lid (3). The lid surrounds pneumatic spring rolling bellows (2) over a part of length. The protective covering with a lid-far end is fastened at the external periphery and outside an upper rolling region of the spring rolling bellows by a clamping ring (10). The clamping ring produces a circulating constriction (11) at the spring rolling bellows.
