ABSTRACT OF THE DISCLOSURE A control circuit for controlling the hydraulic suspension system of an articulated vehicle having a first pair of hydraulic cylinders operatively connected between a drive axle and a tractor frame to control vertical bounce movement of the axle, and a second pair of hydraulic cylinders operatively connected between a tractor and a trailer portion of the articulated vehicle for controlling relative roll movement therebetween. A first valve system directs hydraulic fluid under a first pressure to the head ends of the hydraulic cylinders for supporting the weight of the vehicle and load, and to dampen the bounce motion of the drive wheels and the relative roll motion between the tractor and trailer portions of the articulated vehicle. A gas precharged accumulator and a plurality of flow restrictors disposed in this portion of the circuit, control the spring and viscous damping rates of the cylinders. A pressure reducer communicates hydraulic fluid under n second pressure, lower than the first pressure, to the rod ends of the hydraulic cylinders and to a second gas precharged accumulator. The second gas precharged accumulator functions to insure that the rod ends of the hydraulic cylinders remain oil filled, which allows double action of the cylinders and provides cushioning for the rebound portion of the system.
