Abstract:
The invention concerns a hydropneumatic vehicle suspension, especially for vehicles in which high axle-load differences occur. To adapt the hydropneumatic suspension to high axle-load differences, the hydropneumatic actuators (7, 8) are designed as double-acting hydraulic cylinders of which the head spaces (5, 6) are connected with a first reservoir (12) and the cylinder spaces (22, 23), on the piston-rod side, are connected with a reservoir (24). The pressure in the second reservoir (24) is controlled by a control valve (18) as a function of the pressure in the first reservoir (12). The solution according to the invention is specially suited for use in agricultural vehicles.
