Since 2009, shock absorbers have been supplied alongside another
product, Viking air springs: together, they offer a perfect
combination. Careful balancing of these two components, in fact,
maximises the comfort and safety of the entire suspension system.
Balancing the shock absorber/air spring/steering and suspension set
is essential for softening the impact that tens of thousands of
kilometres of heavy duty driving in all weathers can have on the
vehicle set-up.
Sleeve Type Rolling Lobe Air Springs For Driver's Seats
Air spring driver's seats give the operator's workplace a more
ergonomic and comfortable design, thereby reducing fatigue and
work-related health risks. As a result, Viking Air spring sleeve type cab air springs are used
in commercial vehicle driver's seats. Because of their comfort
construction they can easily be integrated into the seat frame. The
force is transmitted from the seat backing to the air spring
through a control-sleeve lever or a so-called scissors
construction.

Maintenance of the air springs, Vehicle Check-List
Check the air lines and devices of leakage and that
they turns freely.
Check the bellows bearing for damage, correct
fastening, deformation, sharp edges.
Check the shock absorbers for operation and
impermeability as well as tightness and bearing.
Periodically, check nuts and bolts for proper torque.
For specific recommendations see manufacturer's manual.
Check axle suspension, trailing arms and rods for wear.
Check height control valve to see that it is functioning
properly. A properly maintained valve will save unneeded maintenanceexpense.
Routine inspection of all of the above according to
manufacturer's instructions, will extend the life of your vehicle and reduce
your overall maintenance expense.
Air Spring Installation
Before you start installing air springs, make sure you have
all the necessary tools and equipment to perform the repair
safely.
Familiarize yourself with the suspension on which you are
performing the repair by reviewing the manufacturers
service guide.
If you are in doubt about something, ask for assistance from
a qualified suspension specialist, the suspension
manufacturer or the air spring manufacturer; This can save you
a lot of time and aggravation later in the job.
Important tips to remember when installing a new unit
Check levelling valve, linkage and transmission parts for wear
and damage and if necessary replace the damaged parts.
Check that the shock absorber for leakages and take a shock
absorber test. A defective shock absorber must be replaced.
Once the air lines are disconnected, check their entire length
for cracks or other damage. Replace worn parts.
With the air spring removed, other parts of the air
suspension become more accessible. Check for wear or
damage of the frame hangers, trailing arm bushings, torque
rods, the trailing arms and the air spring mounts. When it is
necessary, also replace parts.
Check bearing for air spring bellow for external
damage, deformation, sharp edges and correct fastening.
Before installing the new unit, clean the air spring
mounting plates to ensure proper attachment to the suspension.
Always use new attaching bolts for the installation
and observe the tightening torques. Never use old
bolts, because these can fall out.
Check the linkage of the levelling valve to see that it
is functioning properly. Under load, the linkage should
move from the neutral position up to the intake position. This
lets air into the springs, which brings the arm back to the
neutral position. This lets air into the springs, which brings
the arm back to the neutral position. That opens the
exhaust valve, allowing air to escape until the arm returns to
the neutral position. Then check the driving level.
