Abstract
The invention relates to a plunger for a pneumatic spring (1), which is centered by a centering element (8) on an axle body (5) or on a longitudinal link of a vehicle axis. The aim of the invention is to create an assembly consisting of a plunger and centering element that has a small overall height while simultaneously having a secure joining of the centering element and of the axle body. To this end, the invention provides that the plunger has a shaped element on its side facing the centering element.
