Patent attributes
An air spring strut including an air spring and a damper for springing and damping vibrations of a motor vehicle chassis, the air spring strut being clamped between the body and the chassis of the motor vehicle, including an elastomer air spring bellows clamped between an air spring cover and an air spring rolling piston in an air-tight manner, and which rolls on the air spring rolling piston while forming a rolling fold; an outer guide surrounds the air spring bellows in a sleeve-like manner; a bellows protects the rolling fold from accumulating dirt and is fixed to an outer guide end facing away from the air spring cover; and a vent ventilates a space surrounded by the bellows. The vent has ventilation openings on a bellows end facing the chassis, and additional ventilation openings in the bellows for facilitating air flow within the bellows in the direction of the chassis.
