For HINO Suspension Air Spring

HINO Truck Suspension Air Spring Shock Absorber
In the suspension system of HINO (Hino) trucks, air spring shock absorber (air suspension system) is one of its key components, mainly used to improve driving smoothness, protect cargo and chassis, and adapt to different load requirements

1. Functions of air spring shock absorber
Load adaptation: By adjusting the air pressure in the airbag, it automatically adapts to different loads and keeps the height of the vehicle body stable.

Damping and noise reduction: Compared with leaf springs, air springs can more effectively absorb road impacts and reduce vibration and noise.

Protect cargo: Especially suitable for the transportation of precision instruments, fragile goods and other vibration-sensitive cargo.

Extend chassis life: Reduce damage to the frame and components caused by road impact.

2. Common models of HINO truck air suspension
Some models of HINO's medium and heavy trucks (such as 300 series, 500 series, 700 series) can be equipped with optional or standard air suspension, for example:

HINO 700 (flagship heavy truck): commonly used in long-distance logistics and cold chain transportation, high-end models are equipped with air suspension.

HINO Profia (Japanese market model): Some models offer rear axle air suspension options.

3. Composition of air spring shock absorbers
Air airbag: made of rubber composite material, bears pressure and adjusts height.

Shock absorber (damper): cooperates with the airbag to control the rebound and compression speed.

Height valve: automatically adjusts the airbag inflation and deflation to maintain the set height.

Air tank & compressor: provides a compressed air source (shared with the brake system for some models).

Control system: can manually or automatically adjust the suspension hardness and height.

4. Common Problems and Maintenance
Airbag rupture: Aging, foreign body puncture or overload may cause air leakage, and surface cracks need to be checked regularly.

Air leakage failure: Check the air pipe joint and the sealing of the height valve.

Shock absorber failure: If the vehicle shakes more severely, it may be due to shock absorber oil leakage or valve body damage.

Height abnormality: It may be caused by height valve failure or insufficient air pressure.

Maintenance suggestions:

Clean the airbag surface regularly to prevent corrosive substances from remaining.

Check the sealing of the air pressure system to avoid airbag collapse after long-term parking.

Replace aging parts according to the manufacturer's manual (the general airbag life is about 5-8 years, depending on the use environment).
