Suspension system

It is a suspension system for a agricultural or construction sector pending vehicle (10) described. The suspension system (22) comprises two hydraulic cylinders (18, 20) having a frame (12) opposite to an axle (14, 16) of the vehicle (10) are supported, wherein the hydraulic cylinder (18, 20) in a cross-connect (34, 48, 38, 46) to each other hydraulically are connected, so that a piston-side chamber (26, 28) of a Hydraulic cylinder (18, 20) to the piston rod side chamber (32, 30) of the other hydraulic cylinder (18, 20) is connected, and vice versa, in each case a hydraulic cylinder (18, 20) associated Hydraulic accumulator (36, 40), a hydraulic source (112), a hydraulic tank (88), a control valve means (24, 24 '), an electronic Control unit (107) electrically switchable on-off valves (42, 44, 50, 52) in the cross connection (34, 48, 38, 46) between the Hydraulic accumulators (36, 40) and the hydraulic cylinders (18, 20) are arranged, and first and second supply line (124, 138), the said control valve means (24, 24 ') with the cross-connect (34, 48, 38, 46) connect. To activate a suspension state in critical vehicle conditions to avoid, it is proposed that means for the detection and Compensation of load conditions of the vehicle (10) are provided in the suspension system (22).
