More About Air Suspension
Suspension builders around the world use Vkntech trailer air springs. Why? Because Vkntech air spring has been advancing air suspension technology for more than 12 years. Our commercial trailer suspensions and air springs are challenged, tested and proven every day on thousands of trailers all over the world.
It's no secret that trailers with air suspensions suffer much less wear and tear than those that ride on steel. They enjoy longer cab and vehicle life, lower operating costs, less downtime and fewer failures of expensive onboard equipment. And when trailers ride better, so does their cargo. Trailers equipped with air suspensions often experience less cargo damage than those with conventional suspensions. Firestone trailer suspension springs enable almost perfect load equalization between axles, so cargo stays put.
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.
