916N1 Contitech Bus Suspension Air Bellows 9015 Goodyear V1F21C5 Vihracoastic Air Spring

The air spring in a bus is the core of the suspension system. It uses compressed air to achieve adaptive load-bearing and automatic leveling, significantly improving ride comfort. It enhances vehicle handling stability, provides a kneeling function and ride height adjustment capability, and effectively protects the vehicle structure and components, making it a key intelligent component of modern buses.

Common Troubleshooting

Symptom	Potential Causes	Diagnostic Methods & Corrective Actions
Vehicle Leaning (One Side High, One Side Low)	Height valve linkage stuck or damaged Severe air leak in the corresponding air spring Air line blocked or kinked Faulty height valve	Diagnose: Start the vehicle. Observe if the height valve linkage on the affected side moves normally with body height changes. Listen for audible air leaks. Correct: 1. Lubricate or adjust height valve linkage; 2. Check for leaks on the air spring and lines using soapy water and replace; 3. Inspect and straighten air lines.
Body Will Not Lift (Stays in Kneeled Position)	Air compressor failure/inoperative System pressure too low or major leak Clogged air dryer or multi-circuit valve Main air supply valve closed	Diagnose: Check if the system air pressure gauge is in the normal range. Listen for compressor operation. Check if the air dryer is venting properly. Correct: 1. Repair or replace compressor; 2. Locate and repair major leaks; 3. Replace air dryer or service valve; 4. Open the main air supply valve.
Unstable Vehicle Height	Height valve maladjusted or slow to respond Internal damage to the air spring Intermittent leak in the air system	Diagnose: Test repeatedly on level ground. Observe the response speed of the height valve and the smoothness of air spring inflation/deflation. Correct: 1. Readjust or replace height valve; 2. Inspect air spring for irregular bulges or wear and replace; 3. Tighten all air line connections.
Abnormal Rubbing or Noise During Driving	Air spring rubbing against adjacent components (guard, frame) Air spring surface damaged, cord layer exposed Piston (if equipped) corroded or deformed	Diagnose: Inspect the air spring surface for unusual wear patterns, especially on the sides. Check for correct installation alignment. Correct: 1. Correct the installation position to ensure sufficient clearance; 2. Replace worn or damaged air spring.
Premature Aging or Cracking of Air Spring	Cleaned with inferior chemicals (e.g., gasoline) Prolonged exposure to ozone or extreme weather Long-term corrosion from oil, grease, or solvents	Diagnose: Check the air spring surface for uniform micro-cracks (ozone cracking) or signs of chemical corrosion. Correct: 1. Replace air spring; 2. Avoid cleaning with harmful chemicals; 3. Regularly inspect and clean the air spring surface.
