Core Role and Peterbilt Model Adaptability
AIRSUSTECH air spring model 1T0378 is a core component of rear axle air suspension designed for Peterbilt American long-head trucks (especially for main models such as 579/567/389). Its role goes beyond basic shock absorption and is directly related to vehicle stability, load efficiency and operating costs.
1. Dynamic load support
Load range:
A single spring can support 4.5~7 tons (pressure level needs to be selected according to the rear axle configuration), covering Peterbilt common working conditions:
Light load (container transportation): air pressure 0.6MPa
Heavy load (ore/wood): air pressure 0.9~1.2MPa
Adaptive leveling:
Linked with Peterbilt original height valve (such as Wabco 432020) to keep the height of the cargo compartment constant from the ground and avoid cargo tilting.
2. Improve driving safety
Problem: 1: High-speed rollover tendency
Solution: Lower the center of gravity + enhance lateral support, reduce the roll angle by 35%
Problem 2: Long wheelbase curve drag
Solution: Independent airbag pressure compensation on the rear axle to prevent the tire from leaving the ground
Problem 3: Leaf spring break risk
Solution: No metal fatigue, the precursor of rubber layer break is chronic air leakage
3. Protect key components
Extend the life of the axle: Reduce the impact of the drive axle gear (compared with the leaf spring vibration attenuation rate ↑60%)
Tire protection: Evenly distribute the ground pressure and reduce eccentric wear (tire life ↑20%)
