Spring device for a vehicle

suspension means (1) to a load-bearing and resilient wheel support in a motor vehicle, comprising at least one spring cylinder (2) in a cylinder (4) movable relative piston guided (6), on one side of the one from the cylinder (4) outwardly guided piston rod (8), wherein the piston (6) within the cylinder (4) a cylindrical working chamber (12) by a piston rod (8) enclosing the annular space (14) separates, and wherein the piston (6) on the side of the working space (12) bearing for generating a load supporting spring force (F) against a working pressure (pA) An elastically compressible, in particular pneumatic spring medium (FM) acts, characterized in that the piston rod (8) over a Additional spring cylinder (16) is telescopically variable in length, the Additional spring cylinder (16) with at least one counter-pressure (pG; pG1, pG2) A resiliently compressible, in particular is acted pneumatic opposing spring medium (GM).
