3.2.10 TURNING INTERLOCK HYDRAULIC SYSTEM

The hook trailer is equipped with a passively steered rear steering axle. This solution

facilitates manoeuvring the vehicle, improves stability while driving on turns, reduces

disadvantageous forces in suspension system and chassis which occur while turning.

Consequently, the wear of tyres is reduced and it is easier to drive the tractor with a trailer.

While reversing, the rear axle steering knuckles should be locked. Otherwise, the trailer will

tend to turn in an uncontrolled manner to the left or to the right. The hydraulic system of the

interlock is supplied by the tractor's external hydraulic system through the hydraulic conduits

(2) which are connected to the sockets of a single section of the tractor's hydraulic system by

means of quick couplers (3). The axle is locked by withdrawing or extending the hydraulic

cylinders rods (1). Shock absorber (4) ensures stability of the steering axle and reduces its

excessive vibrations.
