<p>The assembly has a pneumatic spring system with pneumatic spring assemblies (5, 6) that are arranged on top of a frame (2). An emergency spring arrangement (9) includes hydraulic chambers (11) with variable volume, and is designed in such a way that prop-up height is increased by feeding hydraulic fluid to the chambers and reduced by squeezing the hydraulic fluid out of the chambers. The chambers are connected with one another through an interconnecting line (12) at a hydraulic circuit, so that transportation of the hydraulic fluid is achieved between the chambers.</p> |
