What is air spring suspension?

Air suspension is used in place of conventional steel springs in heavy vehicle applications such as buses and trucks, and in some passenger cars. It is widely used on semi trailers and trains (primarily passenger trains).

The purpose of air suspension is to provide a smooth, constant ride quality, but in some cases is used for sports suspension. Modern electronically controlled systems in automobiles and light trucks almost always feature self-leveling along with raising and lowering functions. Although traditionally called air bags or air bellows, the correct term is air spring (although these terms are also used to describe just the rubber bellows element with its end plates).

Truck

• The weight of a truck, and therefore its axle load, fluctuates greatly depending on the payload at any given moment. To meet the resulting suspension requirements, virtually all commercial vehicle manufacturers now employ air springs.
• In providing for level control, air springs also guarantee that the vehicle body maintains a constant road clearance. This, in turn, ensures safe driving regardless of the loading conditions.
• The vehicle body can also be raised or lowered by means of air springs actuated via optional auxiliary manual controls. This is of particular use for adjusting the vehicle body height to the level of a ramp or in placing an interchangeable platform.

Focus On Quality

Viking Air spring is proud to be IATF16949 certified, which marks organizations committed to following a quality management system with several standards. These standards encompass every aspect of our business—from professional employee development and customer service to product design and manufacturing.

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

1. Before you start installing air springs, make sure you have all the necessary tools and equipment to perform the repair safely.
2. Familiarize yourself with the suspension on which you are performing the repair by reviewing the manufacturers service guide.
3. 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.
