Variable steering concept
with „active rear-wheel
steering“
Axles 3, 4 and 5 incorporated into active rear-wheel steering
system; 5 steering methods can be preselected as fixed
programs (P):
P1: On-road steering
Axles 1 and 2 are steered mechanically from the steering
wheel, with hydraulic power assistance. Axles 3, 4 and 5 are
steered actively by a speed-dependent method according to
the front wheel lock angle. Above 30 km/h, axles 3 and 4 are
returned to the straight-ahead position and fixed. Above
60 km/h, axle 5 is also fixed in the straight-ahead position.
The change in steering lock angle according to road speed
results in precise, stable driving road behavior at higher speeds,
reduced tire abrasion and much-improved maneuverability
P2: All-wheel steering
Axles 3, 4 and 5, depending on the wheel lock angle of axle 1,
are turned by means of the steering wheel so that the smallest
turning-circle radius can be obtained
P3: Crabwise steering
Axles 3, 4 and 5 are turned into the same direction as axles 1
and 2 by means of the steering wheel
P4: Steering without superstructure
projection when turning
Axles 3, 4 and 5 are turned in accordance with the wheel lock
angle at axle 1, so that the rear of the vehicle does not project
when cornering
P5: Independent rear-axle steering
Axles 1 and 2 are turned by the steering wheel, axles 3, 4 and 5
are steered independent of the lock angle at 1 and 2 by
pushbuttons; at the same time the lock angle at axle 3 is
adapted to suit the actual situation
• A failure in the rear-axle steering shuts it down; the rear axles
are set to the straight-ahead position by centering rams
• Two independent hydraulic circuits with wheel-driven
and engine-driven hydraulic pumps for the maximum
level of safety
• Two independent control processors (by way of existing
input/output modules) and diversified sensor system
• The entire know-how for the active rear-wheel steering
comes from Liebherr
