Functionality of the rear air spring

The component allows automatic adjustment of the vehicle height as the rear load changes, via the pneumatic system connected to a compressor and control valves.

Main functions:

• Absorption of vertical stresses
• Adjustment of ground clearance according to load
• Improvement of chassis stability under heavy transport conditions
• Reduction of vibrations transmitted to the cargo area and occupants

The efficiency of the air spring is crucial for handling, safety and comfort, especially in commercial vehicles used intensively.

• Wear of the upper or lower mounting points
• Failure of the internal sealing ring
• Ingress of dust or moisture into the spring body

Typical symptoms:

• Rear end lower on one side
• Feeling of instability while driving
• Hissing air noises in the rear area
• Activation of the suspension warning light (where fitted)

These symptoms indicate the need for inspection and possible replacement of the component.
