摘要： A plunger piston for an air spring. The plunger piston is designed as a hollow body and has a base to which an encircling casing part is indirectly or directly coupled. The plunger piston has, at its cover region which faces away from the base, a connecting edge for a bellows and at least one air passage opening. In order to produce this type of a plunger piston in a simple manner with little structural expenditure, the hollow body of this invention has a pot-shaped lower part which forms the base and the casing part. An upper part is placed onto the lower part and is connected to the lower part in an air-tight fashion, and the upper part has the connecting edge.

摘要： A plunger piston for an air spring. The air spring being active between a component which is to be cushioned by springs, in particular the vehicle frame, and a sprung component, in particular the axle carrier of a motor vehicle. The plunger piston is configured as a hollow piston which is connected to the sprung component at the lower plunger-piston end and to a pneumatic-spring bellows which can be loaded with compressed air at an upper plunger-piston head. The pneumatic-spring bellows is connected on the other side to the component which is cushioned by springs, and rolls on the outside of the plunger-piston skirt during suspension movements. The lower plunger-piston end has an open configuration and has a reinforcing element which encircles the edge region of the opening.
