Suspension Hydraulics

Each axle has two (2) hydraulic cylinders (Figure 16) to transfer the load from the frame to the axle . The axles are attached to
the frame by four (4) parallel links, two (2) on each side of each axle, which stabilize the axles and do not support any weight .
The hydraulic cylinders on the left side are connected together as are the hydraulic cylinders on the right side (Figure 17) .
This allows the left side suspension to carry 50% of the weight and the right side suspension to carry the remaining 50% of the
weight .
On each side, the base end of the cylinders are hydraulically connected to each other . The base end of the left side suspension
cylinders DO NOT connect to the base end of the right side suspension cylinders . Once each circuit is charged, the circuit
is closed . With the left side cylinders connected to each other and the right side cylinders connected to each other (Figure
18), the hydraulic fluid can flow from one cylinder base to the other on the same side . This allows for the load to equalize and
permit the axles to move up or down to negotiate ground variations and field approaches . The fast hydraulic fluid flow between
cylinders assures each tire carries the same load as the next without spikes .
The rod ends of all suspension cylinders are connected to a low pressure source to keep them full for seal lubrication . Once
filled, the valve is closed (Figure 19) .
