Abstract
A springing system for a vehicle has a hydraulic actuator and a storage element which holds hydraulic fluid. The system is constructed as a gas accumulator with a holding chamber for the hydraulic fluid and a separate gas chamber, and communicates with the actuator via a connecting line. In order to construct a hydropneumatic springing system for vehicles with a largely linear spring behavior up to complete relief of the load, a further storage element is connected to the actuator via a connecting line and is constructed as an elastomeric accumulator.
