CLASS had another silver medal winner at Agritechnica with their optimising electronic hydraulic positive steering for trailer axles.
In positively steered axle systems, the steered axles of the trailer are steered in a predetermined (fixed) ratio depending on the steering angle of the tractor.
If the basic setting of the system is selected such that the positively steered axles only carry out relatively small steering movements in relation to the steering angle of the tractor, this has positive results for driving stability at fast speeds, but negative consequences for manoeuvrability of the tractor-trailer train.
The tyres are subject to stronger wear in the tight bend. CLASS now offers speed dependent automatic adjustment of the positive steering.
This is adapted optimally and completely automatically to the driving situation. The system always selects the optimal compromise between manoeuvrability and driving stability.
In any tight bends, the driver is given a warning by the articulation angle assistant using an acoustic bell before any collision occurs between the tractor and the trailer drawbar.
