ABSTRACT:
A hydro-pneumatic spring support arrangement, particularly for a vehicle axle with at least one hydraulic spring support cylinder arranged between vehicle chassis and vehicle axle, having a cylinder chamber and a rod end chamber each connected with at least one pressure accumulator and can be selectively connected by valve arrangements with a pressure source and a tank. To influence the ratio of the square of the spring rate to the axle loading and to make the spring rate conform to ballasting, vehicle, or operating conditions, the valve arrangement associated with the rod end chamber is provided with at least one first electromagnetic valve which connects the rod end chamber with the pressure source and is provided with a second electromagnetic valve which connects the rod end chamber with the tank. A pressure sensor is provided, particularly a rod end chamber pressure sensor, the signals of which are utilized for the control of the first and the second electromagnetic valves.
