Function

Cylinder chamber Z8 in the master cylinder (2) is pressurized by the front axle steering (1) and moves the piston rod of the master cylinder (2) to the left. The hydraulic fluid is forced out of cylinder chamber Z2 towards the centering cylinder (3).

This pressurizes cylinder chamber Z5 in the centering cylinder (3) at steering angles greater than 5°.

This causes the piston rod of the centering cylinder (3) to move to the right and the trailing axle is steered to the right.
