The suspension system of a semi-trailer is an important component of the semi-trailer, mainly composed of parts such as elastic elements, guiding devices, and shock absorbers.
| Function | - Buffering and shock absorption: Through elastic elements such as leaf springs and air springs, it mitigates the impacts and vibrations generated due to uneven roads during the vehicle's driving process, ensuring the smooth transportation of goods. At the same time, it reduces the damage to the vehicle's components. |
| - Force transmission and distribution: Reasonably transmits and distributes the vehicle's vertical load, driving force, braking force, and lateral force, etc., to the axle, ensuring the vehicle's driving stability and maneuverability. | |
| - Maintaining the vehicle's posture: The guiding device can keep the correct relative position between the axle and the frame. In situations such as when the vehicle is turning, braking, and accelerating, it prevents abnormal swinging and displacement of the axle, maintaining the vehicle's normal driving posture. | |
| Types | - Leaf spring suspension: It is composed of multiple spring leaves of unequal lengths stacked together. It has a simple structure, low cost, high reliability, and can bear a large load, which is widely used in some traditional semi-trailers. However, its shock absorption performance is relatively poor, and the driving comfort of the vehicle is not ideal. |
| - Air suspension: It uses air springs to achieve buffering and shock absorption, and changes the stiffness of the suspension and the height of the vehicle by adjusting the air pressure in the air springs. The air suspension has good shock absorption performance, which can improve the smoothness and comfort of the vehicle's driving. It can also automatically adjust the vehicle body height according to the weight of the goods to ensure the best driving posture of the vehicle, and is widely used in high-end semi-trailers. | |
| Development trend | With the continuous improvement of the logistics industry's requirements for transportation efficiency and cargo safety, the suspension system of semi-trailers is developing towards intelligence, lightweight, and high reliability. For example, some new types of suspension systems are equipped with electronic control devices, which can monitor the vehicle's driving status and road conditions in real time, and automatically adjust the parameters of the suspension to provide the best shock absorption effect and driving stability. At the same time, the use of new materials and optimized designs can reduce the weight of the suspension system on the premise of ensuring its performance, improving the vehicle's loading capacity and fuel economy. |
| Leaf Spring Suspension | - Number of leaf spring plates: For example, a 10-piece leaf spring. Generally, the more the number of plates, the stronger the load-bearing capacity. |
| - Specifications of leaf springs: Including thickness, width, and length, etc. For instance, a leaf spring of 13×90mm - 106 groups (with a thickness of 13mm). The greater the thickness and width, the higher the stiffness and load-bearing capacity of the suspension. | |
| - Thickness of the bracket side plate: Common ones are 6mm, 8mm, etc. The greater the thickness, the higher the strength and stability of the bracket. | |
| - Thickness of the equalizing beam side plate: There are various options such as 12mm, 14mm, 16mm, etc., which affect the load-bearing capacity and anti-deformation ability of the equalizing beam. | |
| - Width of the equalizing beam: Such as 90mm, 120mm, etc. When the width is larger, it can distribute the load better and improve the stability of the suspension. | |
| Air Suspension | - Model: Different models are suitable for different vehicle types and load requirements. For example, the shengda air suspension system has models like SD 10t, SD 12t, SD 13t, etc. |
| - Installation weight: For example, the installation weight of SD 10t ranges from 475 to 511kg, that of SD 12t ranges from 528 to 567kg, and that of SD13t ranges from 568 to 612kg. | |
| - Load capacity of the suspension/axle system: It determines the maximum load that the suspension can bear. For example, the SD 10t can bear up to 10t, the SD 12t can bear up to 12t, and the SD 13t can bear up to 13.6t | |
| - Ride height: The ride height of the HSDS series is between 355 and 580mm, which can be adjusted according to the vehicle's driving status and the weight of the goods | |
| In addition | - both the leaf spring suspension and the air suspension have some common parameters, such as the number of axles, which are commonly two axles, three axles, etc.; tire specifications, such as 11.00R20, 12R22.5, etc. The size and type of tires will affect the vehicle's load-bearing capacity and driving performance. |
