On vehicles with close axles, self-steering guarantees vehicle
stability and improves manoeuvring.
However, being ready to follow bends is conditioned by weight, speed
and type of tyres used. In particular, highly deformable, strongly
adhering low pressure tyres, fitted to new farm machinery, means
that self-steering reacts late so the vehicle can have difficulty
re-aligning its wheels, with driving, road-holding and abnormal
tread wear problems.
With the new, patented ADR self-steering axles, these problems
belong to the past: steering sensitivity adapts to the wheels and
resolves problems linked to low pressure tyres.
The heart of innovation is the articulation joint: new geometry and
mechanical conception.
The special inclination means it uses vehicle weight and wheel
diameter as “motors” to control reactions and make sure that
self-steering is always “made-to-measure” for the application it is
used on.
Besides innovative geometry, this exceptional sensitivity comes from
new generation materials, mechanical precision and careful assembly.
The ADR self-steering range, from 7 to 16 tons per axle, makes this
important technological innovation available for manufacturers of
all trailer types, both agricultural and industrial.
The possibility to equip these self-steerers with all the ADR brake
range makes them even more versatile and means axle and suspension
groups can be made for all needs.
