Sleeve Type Rolling Lobe Air Springs For Driver's Seats
The working pressure levels between 3 and 7 M pa. So this provides
not only for a comfortable spring characteristic but also for an
infinitely adjustable seat height. The internal pressure is
automatically adapted to the specific weight of the operator by a
height-control valve.
On account of their ergonomic advantage, cab air spring driver's
seats are more or less a standard feature now, not only in buses
and heavy long-distance trucks but increasingly in agricultural and
construction machines such as tractors and wheel loaders and so on.
Air Springs for Cab Suspension
Air Spring Compare With Steel Spring
The advantage that air spring cab suspension has over conventional
steel spring suspension is that of a low natural frequency, which
greatly enhances a commercial vehicle's riding comfort. GUOMAT
sleeve air springs are the type normally used in truck and tractor
cab suspension. Depending on space availability and the design of
add parts, they can set up directly with the vibration damper as
one piece of spring strut or alternatively installed in parallel
arrangement to the dampers.
Warning and Tips
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 maintenance expense.
- 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.
