| Perfect load-distribution |
spring traval per module up to 220mm identical load on all axles less pavement stress |
| Functions | Strengths |
|---|---|
| Brake safety |
load-dependent brake pressure via the load sensing valve valanced braking reduced brake-lining and tyre wear |
| Functions | Strengths |
|---|---|
|
A spring rate accomodated for changing load condition |
no wheel bounce-reduced tyre wear comfort for driver extended lifetime of chassis and opptimum protection of load, chassis ane road under all driving conditions |
• Maintenance Cost Comparison (Leaf and Air)
| Specifications | Leaf suspension | Air suspension |
|---|---|---|
| Suspension |
Abrasion in torque rod bushing Broken leaf spring Deformed alignment |
No abrasion in bushing
(warranty: 3 years) No deformation in alignment |
| Controller | Short lining abrasion period | Extended lining life (1.5 - 2 times) |
| Tires | One-sided abrasion; short tire life |
No one-sided abrasion extended tire life (1.5 - 2 times) |
| 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.
