  • Air spring for vehicles
    Patent number: 9278597
    Abstract: An air spring for a vehicle with a lifting function includes an upper rolling piston and a lower rolling piston disposed opposite to each other. A rolling bellows encloses a compressed air space and has double rolling folds. The pressure effective surfaces of the rolling folds are coordinated with each other in such a manner that, during dynamic spring operation of the air spring over a predetermined spring travel, the pressure effective surface of the rolling fold on the lower rolling piston is larger than the pressure effective surface of the rolling fold on the upper rolling piston.
    Type: Grant
