An hydropneumatic spring unit for the suspension systems of heavy vehicles such as armoured vehicles comprises a piston 5 which is connected by a rod 11 to a swinging axle, not shown, and which works in an hydraulic cylinder 8<11> in communication, through a spring-loaded ring valve 3<11> and ducts 4<11>, with two pressure accumulators 8, 8<1>, each of which contains a compressible medium, e.g. air which is separated from the incompressible hydraulic medium, e.g. oil, by an extensible element such as a diaphragm, or hood 7 and which are disposed one on each side of the cylinder 8<11>. The pressure accumulators 8, 8<11> and the cylinder 811 are closed at their upper ends by heavy screw-in covers 1<1>, 1, the cover 1 accommodating the spring-loaded valve 3 and having a vent screw 2 and the covers 1<1> each screwing down on to a closure member in which the corresponding duct 4 is formed. The hoods 7, which carry light metal discs 14, to prevent them from being sucked into the ducts 4, may be replaced by resilient bags of air. The bottom of the cylinder 8<11> extends into a protective casing 10, a protective covering 16 enclosing the spring unit.
