Abstract
The invention relates to a suspension arrangement (1) for--loading-bearing and resilient wheel support in a motor vehicle, having at least one spring cylinder (2) with a piston (6) which is guided in a cylinder (4) such that it can be moved relative to the latter and which, on one side, has a piston rod (8) guided out of the cylinder (4) in the outward direction. The piston (6) separates, within the cylinder (4), a cylindrical working chamber (12) from an annular chamber (14), which encloses the piston rod (8). On the side of the working chamber (12), in order to generate a load-bearing spring force (F), the piston (6) acts counter to a working pressure (pA) of an elastically compressible, in particular pneumatic spring medium (FM). The piston rod (8) is telescopically variable in length via an additional spring cylinder (16), the additional spring cylinder (16) being subjected at least to a counterpressure (pG; pG1, pG2) of an elastically compressible, in particular pneumatic opposing spring medium (GM).
