Self-Energizing Hydropneumatic Levelling Systems 780052

New hydropneumatic levelling systems with single and twin chambers are presented for application in almost all vehicle makes and types. They are self-energizing and convert the relative movement between axle and body to the advantage of height adjustment. The internal pump work must be understood as load dependent damping, optimizing the settings in relation to load-dependent gas spring rates. It is shown that the units can be designed for similar body frequency within a wide range of payloads.This essay will assist in solving the problems of soft vehicle suspensions with large load differences.
