Lift axle function: OptiTurn
Purpose of this function: To optimise the turning circle of the combination when cornering.
The theoretical wheelbase is shortened in corners by lifting or (partially) relieving the load on
the rear axle. Cornering is detected thanks to the ABS sensors.
This function also works smoothly on vehicles not equipped with lifting axle bellows. In this
case, the rear axle is not lifted, but rather relieved.
When all axles are 100% loaded, the rear axle will not detach from the ground even in the
case of lifting axle bellows. The rear air suspension bellows are vented until the front two
axles are loaded to a maximum of 130%. When fully loaded, the rear axle thus continues
to carry 40% of its maximum load when cornering.
