Abstract
Pneumatic spring, comprising a spring bellows acting as a rolling bellows, whereby the spring bellows borders a spring chamber filled with gas under pressure. The gas is supplied to the spring chamber by means of a pressure connection, whereby the spring bellows is connected on one hand to an axially-movable outer tube, and on the other hand via a roll-off tube. The roll-off tube is engaged with a spring bracket, and the roll-off tube, together with a mounting device on the spring bracket, forms a locking connection which locking connection defines the axial position of the roll-off tube.
