Wheel Deformation Deformed wheel Minimal wheel deformation

Airbag

It acts as a spring that supports the vehicle using compressed air.
If air leaks, the rubber stopper equipped inside the airbag supports the load.
In this case, the buffering force is not sufficient. Drive at 20 Km/h or slower and request customer service.

Protection Valve

If the air pressure in the braking air tank reaches 5.3 kgf/ or higher, it supplies air to the air suspension circuit.

Leveling Valve

Reduces the vibration of the axles caused by uneven road surface to stabilize the driving state of the trailer.
Detects changes to the trailer height and increases/decreases the air in the airbag to keep the trailer height constant regardless of load weight.

Shock Absorber

Absorbs vehicle vibration and improves driving performance.

U-bolt

Fastens the welding between the axle and load beam more firmly.
