Semi trailer suspension is a device connecting the trailer frame (girder) and axle. The main function of trailer suspension is to transfer various forces and moments between the frame and the axle, reduce and eliminate the impact load and vibration transmitted from the road to the frame through the axle, and improve the ride comfort of the trailer. Today, we will focus on the types of semi trailer suspension and the functions and characteristics of various accessories.
According to the installation method, semi trailer suspension is divided into front mounted suspension and reverse mounted suspension.
According to the shape, semi Trailer suspension is divided into American suspension, Japanese suspension, German suspension and European suspension.
According to the bearing capacity, semi trailer suspension are 50 shafts, 60 shafts and 70 shafts.
The processing technology is simple and the configuration space is large, accounting for more than 90% of the Chinese market.
Complex processing technology, light load and low market share.
This kind of suspension has a large export volume. At present, there are many orders from Mexico and Argentina.
It belongs to light suspension, and the steel is 510 high-strength steel, which is difficult to process.

The semi trailer suspension model is based on the height from below the frame to the selected suspension spindle.
The model of semi trailer suspension is determined by the design engineer according to the saddle height, wheel diameter and frame height of the main vehicle. The minimum model is 110#; Up to 320#.
Vehicle Master semi trailer suspension is made of steel produced by state-owned enterprises, such as Angang and Handan Iron and steel, and each feed is provided with quality inspection report.Steel quality is guaranteed.
The punching and blanking process of Vehicle Master semi Trailer suspension is completed at one time to ensure the installation size.
All the key bearing pins are welded by automatic welding machine, which not only ensures the welding quality, but also meets the appearance requirements.
Each process has a testing platform to ensure a pass rate of 99%.
Shot blasting and installation eliminate stress and avoid deformation after installing the main vehicle.
During assembly, the platform is used for installation, so that the bottom of the suspension is vertical and flat, so that customers can save time and high welding efficiency during welding assembly.
