Abstract

One of the major advantages of hydropneumatic suspension systems is the capability to readjust the suspension position after a change of the suspended load, simply by adding or removing hydraulic fluid. This is one of the reasons why a hydropneumatic suspension is virtually always used in combination with a level control. One way to distinguish level control systems is, for example, by the source of energy for the upward leveling (extension of the cylinder). Although most level control systems are connected to an external hydraulic power supply, some systems gain the power from the input side excitations of the suspension itself. All necessary components, namely pump and fluid reservoir, are in this case part of the suspension cylinder. These so called self-pumping systems are particularly used in passenger cars and mostly only partially carry the suspended load in collaboration with a regular mechanical spring.
