The various types of trailer suspension encompass bogie suspension, air suspension, and mechanical suspension. The majority of semi-trailers are equipped with mechanical suspension systems, integrated with leaf springs for optimal performance. Nevertheless, the air suspension trailer boasts superior shock absorption capabilities and is presently the preferred choice for transporting delicate precision instruments and hazardous materials. The focus of this article lies on the air suspension system employed in trailers.
For better handling:
The air suspension system can adjust the stiffness and damping coefficient of the suspension in real time according to the driving state of the vehicle and the operational needs of the driver, so that the vehicle is more stable and accurate in the control. At high speeds or sharp turns, the air suspension can provide better support, allowing the driver to better control the vehicle and improve driving safety.
Adapt to diverse road conditions and load requirements:
By adjusting the air pressure, the air suspension system can achieve stepless adjustment of the suspension stiffness, so as to better adapt to diverse road conditions and load requirements. During load or driving, the air suspension automatically adjusts the suspension height and damping coefficient to maintain body balance and stability.
Extend vehicle life:
The air suspension system can effectively reduce the turbulence and vibration of the vehicle, and reduce the wear and damage of various components of the vehicle. In complex and changeable driving conditions, the air suspension can provide a more stable and safe driving environment for the vehicle, thereby extending the service life of the vehicle.
Improve safety performance:
The air suspension system can quickly absorb impact energy during emergency braking or collision, reducing injuries to passengers. At the same time, by adjusting the height of the body and the suspension stiffness, the air suspension can also improve the wind resistance of the vehicle at high speed, reducing the risk of rollover.
Reduce maintenance costs:
Air suspension systems reduce vehicle maintenance costs by reducing wear and damage to electrical, air conditioning, exhaust systems, axle, body and chassis components. At the same time, due to the relatively complex structure of the air suspension system, its high reliability and long life also reduce the need for frequent replacement parts.
To sum up, air suspension, with its unique advantages and wide application prospects, is playing an increasingly important role in the automotive industry. With the continuous progress of technology and the gradual reduction of costs, the air suspension system is expected to be applied and promoted on more models.
