Automatic speed-independent adjustment of the steered axle with Claas

In forced-steering axle systems, the guided axles of the trailer are steered according to the tractor's steering angle, following a previously set ratio.

When the system is set up so that the forced-steering axles make only a slight steering movement relative to the tractor's steering angle, this is very positive for driving stability at high speed on the one hand, but all the more negative for the maneuverability of the combination or for tires that slip heavily in tight turns.

When the steering angle of the forced-steering axles is larger, maneuverability is improved, at the expense of driving stability.

The Claas solution now offers automatic, speed-independent adjustment of the forced-steering axle. It is thus adjusted completely autonomously to the current driving situation. Related operating errors are therefore avoided, as the system always selects the optimal compromise between maneuverability and driving stability.

In addition, when driving in tight turns, the driver is warned by an acoustic signal from the articulation angle assistant before a possible collision between the tractor and the trailer drawbar.
