Patent ID: 7055831

Claim:
A hydropneumatic, level-regulated axle suspension for front and rear axles on vehicles, comprising: two double-acting hydraulic suspension cylinders, whose cylinder spaces are each connected to a first pressure accumulator and whose annuli on a piston side are connected to a second pressure accumulator, wherein the axle suspension for the front axle ( 39 ) and the rear axle ( 40 ) is designed as a reversible double-function axle suspension, so that each axle ( 39 , 40 ) is switchable (i) as an oscillating axle in a cylinder transverse combination in which the cylinder spaces on a given axle communicate and the annuli on the same axle communicate, or (ii) as a stabilizing axle in a cross combination in which the cylinder space of each cylinder on a given axle communicates with the annulus of the other cylinder on the same axle; wherein the rear axle of the vehicle is switched as the stabilizing axle and the front axle of the vehicle is switched as an oscillating axle when there is a lower axle load on the front axle of the vehicle, and the rear axle is switched as an oscillating axle and the front axle of the vehicle is switched as the stabilizing axle when there is a lower axle load on the rear axle of the vehicle.
