ANNEX 2
INSTRUCTIONS FOR THE PASSIVE SUSPENSION OF AN
Axle (closed circuit)
1- PRESENTATION OF THE SYSTEM
All axles are equipped with an independent damping system that are
said to be with passive or closed circuit suspension.
.
The circuit is completely independent of the tractor. The suspension is
set once and for all (even though it is changed occasionally). The adjustment is
made so that an optimal displacement is supported. The cylinder movement being
200 mm, the optimal displacement is ± 100 mm.
The user cannot correct the height of his vehicle on the move.
2- OPERATING PRINCIPLE
The system is composed mainly of the following components:
4 suspension cylinders for a vehicle with 2 axles (6 for a 3-axled
vehicle)
1 hydraulic suspension control block
2 piston accumulators
