Abstract

The invention relates to a pneumatic spring arrangement (1) comprising at least the following components, namely a pneumatic spring lid (2), a pneumatic spring piston (3), pneumatic spring bellows (7), a vibration damper (11) with a rucksack module (14; e.g. an ADS module) and a protective collar (17) with a first connection area (B; inside diameter D1) and a second connection area (B′; inside diameter D2). The inventive pneumatic spring arrangement is characterized in that the inside diameters (D1 , D2) of the first (B) and the second (B′) connection area pertaining to the protective collar (17) have a size so that the protective collar can be slid over the ruck sack module (14). The excess free space within the second connection area (B′) of the protective collar (17) can be filled with an adapter element (18) in a compensating manner. The adapter element (18) can be closed to from ring-shaped formation by means of a closing system and thus encompasses the end area (6) of the pneumatic spring piston (3). The novel protective collar (17) with the adapter element (18) can be used as a tire gaiter as well as a series collar.
