Why are Renault Trucks Cabs Equipped with Air Springs and Shock Absorbers?

1. Significantly Improved Driving Comfort
Excellent Shock Absorption: Air springs absorb road bumps and vibrations using compressed air. Compared to traditional steel springs or rubber shock absorbers, they more effectively isolate high-frequency vibrations (such as gravel roads) and low-frequency oscillations (such as potholes), reducing driver fatigue.

2. Protecting Driver Health
Long-term exposure to severe vibration can cause spinal and joint injuries or chronic fatigue in professional drivers. Air springs reduce these health risks by reducing vibration transmitted to the cab, thus complying with occupational health and safety standards.

3. Enhanced Driving Safety
Stable Control: Reduced cab oscillation improves driver control precision, especially during emergency steering or braking, preventing vibration-induced misoperation.

Stable Vision: A stable cab ensures the driver's field of vision is unobstructed by bumps, improving driving safety.

4. Extended Vehicle Component Life
Reduced vibration transmission not only protects the driver but also reduces mechanical stress on components such as the cab structure, electronic equipment, and instrumentation, reducing wear and failure rates, and lowering maintenance costs.
