Bogie angle altering process for multi-axle truck trailer

摘要

The angle altering process involves having the suspension elements (14, 15, 16) of the individual axles separated from the service circuit. Thus forming independent service circuits. By setting different pressures in these circuits, the required angle of the trailer can be achieved. The suspension system may be pneumatic. The circuit for one of the elements (14) for a separate axle can be connected to a pressurized store air (10). The trailer may have a rigid towbar, the ground clearance of which is adjustable.
